Concerning praise and blame I have spoken in III. xxix. note: the time has now come to treat of the remaining terms. But I must first say a few words concerning man in the state of nature and in society.

Every man exists by sovereign natural right, and, consequently, by sovereign natural right performs those actions which follow from the necessity of his own nature; therefore by sovereign natural right every man judges what is good and what is bad, takes care of his own advantage according to his own disposition (IV. xix. and IV. xx.), avenges the wrongs done to him (III. xl. Coroll. ii.), and endeavours to preserve that which he loves and to destroy that which he hates (III. xxviii.). Now, if men lived under the guidance of reason, everyone would remain in possession of this his right, without any injury being done to his neighbour (IV. xxxv. Coroll. i.). But seeing that they are a prey to their emotions, which far surpass human power or virtue (IV. vi.), they are often drawn in different directions, and being at variance one with another (IV. xxxiii. xxxiv.), stand in need of mutual help (IV. xxxv. note). Wherefore, in order that men may live together in harmony, and may aid one another, it is necessary that they should forego their natural right, and, for the sake of security, refrain from all actions which can injure their fellow—men. The way in which this end can be obtained, so that men who are necessarily a prey to their emotions (IV. iv. Coroll.), inconstant, and diverse, should be able to render each other mutually secure, and feel mutual trust, is evident from IV. vii. and III. xxxix. It is there shown, that an emotion can only be restrained by an emotion stronger than, and contrary to itself, and that men avoid inflicting injury through fear of incurring a greater injury themselves.

On this law society can be established, so long as it keeps in its own hand the right, possessed by everyone, of avenging injury, and pronouncing on good and evil; and provided it also possesses the power to lay down a general rule of conduct, and to pass laws sanctioned, not by reason, which is powerless in restraining emotion, but by threats (IV. xvii. note). Such a society established with laws and the power of preserving itself is called a State, while those who live under its protection are called citizens. We may readily understand that there is in the state of nature nothing, which by universal consent is pronounced good or bad; for in the state of nature everyone thinks solely of his own advantage, and according to his disposition, with reference only to his individual advantage, decides what is good or bad, being bound by no law to anyone besides himself.

In the state of nature, therefore, sin is inconceivable; it can only exist in a state, where good and evil are pronounced on by common consent, and where everyone is bound to obey the State authority. Sin, then, is nothing else but disobedience, which is therefore punished by the right of the State only. Obedience, on the other hand, is set down as merit, inasmuch as a man is thought worthy of merit, if he takes delight in the advantages which a State provides.

Again, in the state of nature, no one is by common consent master of anything, nor is there anything in nature, which can be said to belong to one man rather than another: all things are common to all. Hence, in the state of nature, we can conceive no wish to render to every man his own, or to deprive a man of that which belongs to him; in other words, there is nothing in the state of nature answering to justice and injustice. Such ideas are only possible in a social state, when it is decreed by common consent what belongs to one man and what to another.

From all these considerations it is evident, that justice and injustice, sin and merit, are extrinsic ideas, and not attributes which display the nature of the mind. But I have said enough.

PROP. XXXVIII. Whatsoever disposes the human body, so as to render it capable of being affected in an increased number of ways, or of affecting external bodies in an increased number of ways, is useful to man; and is so, in proportion as the body is thereby rendered more capable of being affected or affecting other bodies in an increased number of ways; contrariwise, whatsoever renders the body less capable in this respect is hurtful to man.

Proof.—Whatsoever thus increases the capabilities of the body increases also the mind's capability of perception (II. xiv.); therefore, whatsoever thus disposes the body and thus renders it capable, is necessarily good or useful (IV. xxvi. xxvii.); and is so in proportion to the extent to which it can render the body capable; contrariwise (II. xiv., IV. xxvi. xxvii.), it is hurtful, if it renders the body in this respect less capable. Q.E.D.

PROP. XXXIX. Whatsoever brings about the preservation of the proportion of motion and rest, which the parts of the human body mutually possess, is good; contrariwise, whatsoever causes a change in such proportion is bad.

Proof.—The human body needs many other bodies for its preservation (II. Post. iv.). But that which constitutes the specific reality (forma) of a human body is, that its parts communicate their several motions one to another in a certain fixed proportion (Def. before Lemma iv. after II. xiii.). Therefore, whatsoever brings about the preservation of the proportion between motion and rest, which the parts of the human body mutually possess, preserves the specific reality of the human body, and consequently renders the human body capable of being affected in many ways and of affecting external bodies in many ways; consequently it is good (by the last Prop.). Again, whatsoever brings about a change in the aforesaid proportion causes the human body to assume another specific character, in other words (see Preface to this Part towards the end, though the point is indeed self—evident), to be destroyed, and consequently totally incapable of being affected in an increased numbers of ways; therefore it is bad. Q.E.D.

Note.—The extent to which such causes can injure or be of service to the mind will be explained in the Fifth Part. But I would here remark that I consider that a body undergoes death, when the proportion of motion and rest which obtained mutually among its several parts is changed. For I do not venture to deny that a human body, while keeping the circulation of the blood and other properties, wherein the life of a body is thought to consist, may none the less be changed into another nature totally different from its own. There is no reason, which compels me to maintain that a body does not die, unless it becomes a corpse; nay, experience would seem to point to the opposite conclusion. It sometimes happens, that a man undergoes such changes, that I should hardly call him the same. As I have heard tell of a certain Spanish poet, who had been seized with sickness, and though he recovered therefrom yet remained so oblivious of his past life, that he would not believe the plays and tragedies he had written to be his own: indeed, he might have been taken for a grown—up child, if he had also forgotten his native tongue. If this instance seems incredible, what shall we say of infants? A man of ripe age deems their nature so unlike his own, that he can only be persuaded that he too has been an infant by the analogy of other men. However, I prefer to leave such questions undiscussed, lest I should give ground to the superstitious for raising new issues.

PROP. XL. Whatsoever conduces to man's social life, or causes men to live together in harmony, is useful, whereas whatsoever brings discord into a State is bad.

Proof.—For whatsoever causes men to live together in harmony also causes them to live according to reason (IV. xxxv.), and is therefore (IV. xxvi. xxvii.) good, and (for the same reason) whatsoever brings about discord is bad. Q.E.D.

PROP. XLI. Pleasure in itself is not bad but good: contrariwise, pain in itself is bad.

Proof.—Pleasure (III. xi. and note) is emotion, whereby the body's power of activity is increased or helped; pain is emotion, whereby the body's power of activity is diminished or checked; therefore (IV. xxxviii.) pleasure in itself is good, &c. Q.E.D.

PROP. XLII. Mirth cannot be excessive, but is always good; contrariwise, Melancholy is always bad.

Proof.—Mirth (see its Def. in III. xi. note) is pleasure, which, in so far as it is referred to the body, consists in all parts of the body being affected equally: that is (III. xi.), the body's power of activity is increased or aided in such a manner, that the several parts maintain their former proportion of motion and rest; therefore Mirth is always good (IV. xxxix.), and cannot be excessive. But Melancholy (see its Def. in the same note to III. xi.) is pain, which, in so far as it is referred to the body, consists in the absolute decrease or hindrance of the body's power of activity; therefore (IV. xxxviii.) it is always bad. Q.E.D.

PROP. XLIII. Stimulation may be excessive and bad; on the other hand, grief may be good, in so far as stimulation or pleasure is bad.

Proof.—Localized pleasure or stimulation (titillatio) is pleasure, which, in so far as it is referred to the body, consists in one or some of its parts being affected more than the rest (see its Definition, III. xi. note); the power of this emotion may be sufficient to overcome other actions of the body (IV. vi.), and may remain obstinately fixed therein, thus rendering it incapable of being affected in a variety of other ways: therefore (IV. xxxviii.) it may be bad. Again, grief, which is pain, cannot as such be good (IV. xli.). But, as its force and increase is defined by the power of an external cause compared with our own (IV. v.), we can conceive infinite degrees and modes of strength in this emotion (IV. iii.); we can, therefore, conceive it as capable of restraining stimulation, and preventing its becoming excessive, and hindering the body's capabilities; thus, to this extent, it will be good. Q.E.D.

PROP. XLIV. Love and desire may be excessive.

Proof.—Love is pleasure, accompanied by the idea of an external cause (Def. of Emotions, vi.); therefore stimulation, accompanied by the idea of an external cause is love (III. xi. note); hence love maybe excessive. Again, the strength of desire varies in proportion to the emotion from which it arises (III. xxxvii.). Now emotion may overcome all the rest of men's actions (IV. vi.); so, therefore, can desire, which arises from the same emotion, overcome all other desires, and become excessive, as we showed in the last proposition concerning stimulation.

Note.—Mirth, which I have stated to be good, can be conceived more easily than it can be observed. For the emotions, whereby we are daily assailed, are generally referred to some part of the body which is affected more than the rest; hence the emotions are generally excessive, and so fix the mind in the contemplation of one object, that it is unable to think of others; and although men, as a rule, are a prey to many emotions—and very few are found who are always assailed by one and the same—yet there are cases, where one and the same emotion remains obstinately fixed. We sometimes see men so absorbed in one object, that, although it be not present, they think they have it before them; when this is the case with a man who is not asleep, we say he is delirious or mad; nor are those persons who are inflamed with love, and who dream all night and all day about nothing but their mistress, or some woman, considered as less mad, for they are made objects of ridicule. But when a miser thinks of nothing but gain or money, or when an ambitious man thinks of nothing but glory, they are not reckoned to be mad, because they are generally harmful, and are thought worthy of being hated. But, in reality, Avarice, Ambition, Lust, &c., are species of madness, though they may not be reckoned among diseases.

PROP. XLV. Hatred can never be good.

Proof.—When we hate a man, we endeavour to destroy him (III. xxxix.), that is (IV. xxxvii.), we endeavour to do something that is bad. Therefore, &c. Q.E.D.

N.B. Here, and in what follows, I mean by hatred only hatred towards men.

Corollary I.—Envy, derision, contempt, anger, revenge, and other emotions attributable to hatred, or arising therefrom, are bad; this is evident from III. xxxix. and IV. xxxvii.

Corollary II.—Whatsoever we desire from motives of hatred is base, and in a State unjust. This also is evident from III. xxxix., and from the definitions of baseness and injustice in IV. xxxvii. note.

Note.—Between derision (which I have in Coroll. I. stated to be bad) and laughter I recognize a great difference. For laughter, as also jocularity, is merely pleasure; therefore, so long as it be not excessive, it is in itself good (IV. xli.). Assuredly nothing forbids man to enjoy himself, save grim and gloomy superstition. For why is it more lawful to satiate one's hunger and thirst than to drive away one's melancholy? I reason, and have convinced myself as follows: No deity, nor anyone else, save the envious, takes pleasure in my infirmity and discomfort, nor sets down to my virtue the tears, sobs, fear, and the like, which axe signs of infirmity of spirit; on the contrary, the greater the pleasure wherewith we are affected, the greater the perfection whereto we pass; in other words, the more must we necessarily partake of the divine nature. Therefore, to make use of what comes in our way, and to enjoy it as much as possible (not to the point of satiety, for that would not be enjoyment) is the part of a wise man. I say it is the part of a wise man to refresh and recreate himself with moderate and pleasant food and drink, and also with perfumes, with the soft beauty of growing plants, with dress, with music, with many sports, with theatres, and the like, such as every man may make use of without injury to his neighbour. For the human body is composed of very numerous parts, of diverse nature, which continually stand in need of fresh and varied nourishment, so that the whole body may be equally capable of performing all the actions, which follow from the necessity of its own nature; and, consequently, so that the mind may also be equally capable of understanding many things simultaneously. This way of life, then, agrees best with our principles, and also with general practice; therefore, if there be any question of another plan, the plan we have mentioned is the best, and in every way to be commended. There is no need for me to set forth the matter more clearly or in more detail.

PROP. XLVI. He, who lives under the guidance of reason, endeavours, as far as possible, to render back love, or kindness, for other men's hatred, anger, contempt, &c., towards him.

Proof.—All emotions of hatred are bad (IV. xlv. Coroll. i.); therefore he who lives under the guidance of reason will endeavour, as far as possible, to avoid being assailed by such emotions (IV. xix.); consequently, he will also endeavour to prevent others being so assailed (IV. xxxvii.). But hatred is increased by being reciprocated, and can be quenched by love (III. xliii.), so that hatred may pass into love (III. xliv.); therefore he who lives under the guidance of reason will endeavour to repay hatred with love, that is, with kindness. Q.E.D.

Note.—He who chooses to avenge wrongs with hatred is assuredly wretched. But he, who strives to conquer hatred with love, fights his battle in joy and confidence; he withstands many as easily as one, and has very little need of fortune's aid. Those whom he vanquishes yield joyfully, not through failure, but through increase in their powers; all these consequences follow so plainly from the mere definitions of love and understanding, that I have no need to prove them in detail.

PROP. XLVII. Emotions of hope and fear cannot be in themselves good.

Proof.—Emotions of hope and fear cannot exist without pain. For fear is pain (Def. of the Emotions, xiii.), and hope (Def. of the Emotions, Explanation xii. and xiii.) cannot exist without fear; therefore (IV. xli.) these emotions cannot be good in themselves, but only in so far as they can restrain excessive pleasure (IV. xliii.). Q.E.D.

Note.—We may add, that these emotions show defective knowledge and an absence of power in the mind; for the same reason confidence, despair, joy, and disappointment are signs of a want of mental power. For although confidence and joy are pleasurable emotions, they nevertheless imply a preceding pain, namely, hope and fear. Wherefore the more we endeavour to be guided by reason, the less do we depend on hope; we endeavour to free ourselves from fear, and, as far as we can, to dominate fortune, directing our actions by the sure counsels of wisdom.

PROP. XLVIII. The emotions of over—esteem and disparagement are always bad.

Proof.—These emotions (see Def. of the Emotions, xxi. xxii.) are repugnant to reason; and are therefore (IV. xxvi. xxvii.) bad. Q.E.D.

PROP. XLIX. Over—esteem is apt to render its object proud.

Proof.—If we see that any one rates us too highly, for love's sake, we are apt to become elated (III. xli.), or to be pleasurably affected (Def. of the Emotions, xxx.); the good which we hear of ourselves we readily believe (III. xxv.); and therefore, for love's sake, rate ourselves too highly; in other words, we are apt to become proud. Q.E.D.

PROP. L. Pity, in a man who lives under the guidance of reason, is in itself bad and useless.

Proof.—Pity (Def. of the Emotions, xviii.) is a pain, and therefore (IV. xli.) is in itself bad. The good effect which follows, namely, our endeavour to free the object of our pity from misery, is an action which we desire to do solely at the dictation of reason (IV. xxxvii.); only at the dictation of reason are we able to perform any action, which we know for certain to be good (IV. xxvii.); thus, in a man who lives under the guidance of reason, pity in itself is useless and bad. Q.E.D.

Note.—He who rightly realizes, that all things follow from the necessity of the divine nature, and come to pass in accordance with the eternal laws and rules of nature, will not find anything worthy of hatred, derision, or contempt, nor will he bestow pity on anything, but to the utmost extent of human virtue he will endeavour to do well, as the saying is, and to rejoice. We may add, that he, who is easily touched with compassion, and is moved by another's sorrow or tears, often does something which he afterwards regrets; partly because we can never be sure that an action caused by emotion is good, partly because we are easily deceived by false tears. I am in this place expressly speaking of a man living under the guidance of reason. He who is moved to help others neither by reason nor by compassion, is rightly styled inhuman, for (III. xxvii.) he seems unlike a man.

PROP. LI. Approval is not repugnant to reason, but can agree therewith and arise therefrom.

Proof.—Approval is love towards one who has done good to another (Def. of the Emotions, xix.); therefore it may be referred to the mind, in so far as the latter is active (III. lix.), that is (III. iii.), in so far as it understands; therefore, it is in agreement with reason, &c. Q.E.D.

Another Proof.—He, who lives under the guidance of reason, desires for others the good which he seeks for himself (IV. xxxvii.); wherefore from seeing someone doing good to his fellow his own endeavour to do good is aided; in other words, he will feel pleasure (III. xi. note) accompanied by the idea of the benefactor. Therefore he approves of him. Q.E.D.

Note.—Indignation as we defined it (Def. of the Emotions, xx.) is necessarily evil (IV. xlv.); we may, however, remark that, when the sovereign power for the sake of preserving peace punishes a citizen who has injured another, it should not be said to be indignant with the criminal, for it is not incited by hatred to ruin him, it is led by a sense of duty to punish him.

PROP. LII. Self—approval may arise from reason, and that which arises from reason is the highest possible.

Proof.—Self—approval is pleasure arising from a man's contemplation of himself and his own power of action (Def. of the Emotions, xxv.). But a man's true power of action or virtue is reason herself (III. iii.), as the said man clearly and distinctly contemplates her (II. xl. xliii.); therefore self—approval arises from reason. Again, when a man is contemplating himself, he only perceived clearly and distinctly or adequately, such things as follow from his power of action (III. Def. ii.), that is (III. iii.), from his power of understanding; therefore in such contemplation alone does the highest possible self—approval arise. Q.E.D.

Note.—Self—approval is in reality the highest object for which we can hope. For (as we showed in IV. xxv.) no one endeavours to preserve his being for the sake of any ulterior object, and, as this approval is more and more fostered and strengthened by praise (III. liii. Coroll.), and on the contrary (III. lv. Coroll.) is more and more disturbed by blame, fame becomes the most powerful of incitements to action, and life under disgrace is almost unendurable.

PROP. LIII. Humility is not a virtue, or does not arise from reason.

Proof.—Humility is pain arising from a man's contemplation of his own infirmities (Def. of the Emotions, xxvi.). But, in so far as a man knows himself by true reason, he is assumed to understand his essence, that is, his power (III. vii.). Wherefore, if a man in self—contemplation perceives any infirmity in himself, it is not by virtue of his understanding himself, but (III. lv.) by virtue of his power of activity being checked. But, if we assume that a man perceives his own infirmity by virtue of understanding something stronger than himself, by the knowledge of which he determines his own power of activity, this is the same as saying that we conceive that a man understands himself distinctly (IV. xxvi.), because[14] his power of activity is aided. Wherefore humility, or the pain which arises from a man's contemplation of his own infirmity, does not arise from the contemplation or reason, and is not a virtue but a passion. Q.E.D.

[14] Land reads: "Quod ipsius agendi potentia juvatur"—which I have translated above. He suggests as alternative readings to 'quod', 'quo' (= whereby) and 'quodque' (= and that).

PROP. LIV. Repentance is not a virtue, or does not arise from reason; but he who repents of an action is doubly wretched or infirm.

Proof.—The first part of this proposition is proved like the foregoing one. The second part is proved from the mere definition of the emotion in question (Def. of the Emotions, xxvii.). For the man allows himself to be overcome, first, by evil desires; secondly, by pain.

Note.—As men seldom live under the guidance of reason, these two emotions, namely, Humility and Repentance, as also Hope and Fear, bring more good than harm; hence, as we must sin, we had better sin in that direction. For, if all men who are a prey to emotion were all equally proud, they would shrink from nothing, and would fear nothing; how then could they be joined and linked together in bonds of union? The crowd plays the tyrant, when it is not in fear; hence we need not wonder that the prophets, who consulted the good, not of a few, but of all, so strenuously commended Humility, Repentance, and Reverence. Indeed those who are a prey to these emotions may be led much more easily than others to live under the guidance of reason, that is, to become free and to enjoy the life of the blessed.

PROP. LV. Extreme pride or dejection indicates extreme ignorance of self.

Proof.—This is evident from Def. of the Emotions, xxviii. and xxix.

PROP. LVI. Extreme pride or dejection indicates extreme infirmity of spirit.

Proof.—The first foundation of virtue is self—preservation (IV. xxii. Coroll.) under the guidance of reason (IV. xxiv.). He, therefore, who is ignorant of himself, is ignorant of the foundation of all virtues, and consequently of all virtues. Again, to act virtuously is merely to act under the guidance of reason (IV. xxiv.): now he, that acts under the guidance of reason, must necessarily know that he so acts (II. xliii.). Therefore he who is in extreme ignorance of himself, and consequently of all virtues, acts least in obedience to virtue; in other words (IV. Def. viii.), is most infirm of spirit. Thus extreme pride or dejection indicates extreme infirmity of spirit. Q.E.D.

Corollary.—Hence it most clearly follows, that the proud and the dejected specially fall a prey to the emotions.

Note.—Yet dejection can be more easily corrected than pride; for the latter being a pleasurable emotion, and the former a painful emotion, the pleasurable is stronger than the painful (IV. xviii.).

PROP. LVII. The proud man delights in the company of flatterers and parasites, but hates the company of the high—minded.

Proof.—Pride is pleasure arising from a man's over estimation of himself (Def. of the Emotions, xxviii. and vi.); this estimation the proud man will endeavour to foster by all the means in his power (III. xiii. note); he will therefore delight in the company of flatterers and parasites (whose character is too well known to need definition here), and will avoid the company of high—minded men, who value him according to his deserts. Q.E.D.

Note.—It would be too long a task to enumerate here all the evil results of pride, inasmuch as the proud are a prey to all the emotions, though to none of them less than to love and pity. I cannot, however, pass over in silence the fact, that a man may be called proud from his underestimation of other people; and, therefore, pride in this sense may be defined as pleasure arising from the false opinion, whereby a man may consider himself superior to his fellows. The dejection, which is the opposite quality to this sort of pride, may be defined as pain arising from the false opinion, whereby a man may think himself inferior to his fellows. Such being the ease, we can easily see that a proud man is necessarily envious (III. xli. note), and only takes pleasure in the company, who fool his weak mind to the top of his bent, and make him insane instead of merely foolish.

Though dejection is the emotion contrary to pride, yet is the dejected man very near akin to the proud man. For, inasmuch as his pain arises from a comparison between his own infirmity and other men's power or virtue, it will be removed, or, in other words, he will feel pleasure, if his imagination be occupied in contemplating other men's faults; whence arises the proverb, "The unhappy are comforted by finding fellow—sufferers." Contrariwise, he will be the more pained in proportion as he thinks himself inferior to others; hence none are so prone to envy as the dejected, they are specially keen in observing men's actions, with a view to fault—finding rather than correction, in order to reserve their praises for dejection, and to glory therein, though all the time with a dejected air. These effects follow as necessarily from the said emotion, as it follows from the nature of a triangle, that the three angles are equal to two right angles. I have already said that I call these and similar emotions bad, solely in respect to what is useful to man. The laws of nature have regard to nature's general order, whereof man is but a part. I mention this, in passing, lest any should think that I have wished to set forth the faults and irrational deeds of men rather than the nature and properties of things. For, as I said in the preface to the third Part, I regard human emotions and their properties as on the same footing with other natural phenomena. Assuredly human emotions indicate the power and ingenuity, of nature, if not of human nature, quite as fully as other things which we admire, and which we delight to contemplate. But I pass on to note those qualities in the emotions, which bring advantage to man, or inflict injury upon him.

PROP. LVIII. Honour (gloria) is not repugnant to reason, but may arise therefrom.

Proof.—This is evident from Def. of the Emotions, xxx., and also from the definition of an honourable man (IV. xxxvii. note. i.).

Note—Empty honour, as it is styled, is self—approval, fostered only by the good opinion of the populace; when this good opinion ceases there ceases also the self—approval, in other words, the highest object of each man's love (IV. lii. note); consequently, he whose honour is rooted in popular approval must, day by day, anxiously strive, act, and scheme in order to retain his reputation. For the populace is variable and inconstant, so that, if a reputation be not kept up, it quickly withers away. Everyone wishes to catch popular applause for himself, and readily represses the fame of others. The object of the strife being estimated as the greatest of all goods, each combatant is seized with a fierce desire to put down his rivals in every possible way, till he who at last comes out victorious is more proud of having done harm to others than of having done good to himself. This sort of honour, then, is really empty, being nothing.

The points to note concerning shame may easily be inferred from what was said on the subject of mercy and repentance. I will only add that shame, like compassion, though not a virtue, is yet good, in so far as it shows, that the feeler of shame is really imbued with the desire to live honourably; in the same way as suffering is good, as showing that the injured part is not mortified. Therefore, though a man who feels shame is sorrowful, he is yet more perfect than he, who is shameless, and has no desire to live honourably.

Such are the points which I undertook to remark upon concerning the emotions of pleasure and pain; as for the desires, they are good or bad according as they spring from good or evil emotions. But all, in so far as they are engendered in us by emotions wherein the mind is passive, are blind (as is evident from what was said in IV. xliv. note), and would be useless, if men could easily, be induced to live by the guidance of reason only, as I will now briefly, show.

PROP. LIX. To all the actions, whereto we are determined by emotion wherein the mind is passive; we can be determined without emotion by reason.

Proof.—To act rationally, is nothing else (III. iii. and Def. ii.) but to perform those actions, which follow from the necessity, of our nature considered in itself alone. But pain is bad, in so far as it diminishes or checks the power of action (IV. xli.); wherefore we cannot by pain be determined to any action, which we should be unable to perform under the guidance of reason. Again, pleasure is bad only in so far as it hinders a man's capability for action (IV. xli. xliii.); therefore to this extent we could not be determined by it to any action, which we could not perform under the guidance of reason. Lastly, pleasure, in so far as it is good, is in harmony with reason (for it consists in the fact that a man's capability for action is increased or aided); nor is the mind passive therein, except in so far as a man's power of action is not increased to the extent of affording him an adequate conception of himself and his actions (III. iii., and note).

Wherefore, if a man who is pleasurably affected be brought to such a state of perfection, that he gains an adequate conception of himself and his own actions, he will be equally, nay more, capable of those actions, to which he is determined by emotion wherein the mind is passive. But all emotions are attributable to pleasure, to pain, or to desire (Def. of the Emotions, iv. explanation); and desire (Def. of the Emotions, i.) is nothing else but the attempt to act; therefore, to all actions, &c. Q.E.D.

Another Proof.—A given action is called bad, in so far as it arises from one being affected by hatred or any evil emotion. But no action, considered in itself alone, is either good or bad (as we pointed out in the preface to Pt. IV.), one and the same action being sometimes good, sometimes bad; wherefore to the action which is sometimes bad, or arises from some evil emotion, we may be led by reason (IV. xix.). Q.E.D.

Note.—An example will put this point in a clearer light. The action of striking, in so far as it is considered physically, and in so far as we merely look to the fact that a man raises his arm, clenches his fist, and moves his whole arm violently downwards, is a virtue or excellence which is conceived as proper to the structure of the human body. If, then, a man, moved by anger or hatred, is led to clench his fist or to move his arm, this result takes place (as we showed in Pt. II.), because one and the same action can be associated with various mental images of things; therefore we may be determined to the performance of one and the same action by confused ideas, or by clear and distinct ideas. Hence it is evident that every desire which springs from emotion, wherein the mind is passive, would become useless, if men could be guided by reason. Let us now see why desire which arises from emotion, wherein the mind is passive, is called by us blind.

PROP. LX. Desire arising from a pleasure or pain, that is not attributable to the whole body, but only to one or certain parts thereof, is without utility in respect to a man as a whole.

Proof.—Let it be assumed, for instance, that A, a part of a body, is so strengthened by some external cause, that it prevails over the remaining parts (IV. vi.). This part will not endeavour to do away with its own powers, in order that the other parts of the body may perform its office; for this it would be necessary for it to have a force or power of doing away with its own powers, which (III. vi.) is absurd. The said part, and, consequently, the mind also, will endeavour to preserve its condition. Wherefore desire arising from a pleasure of the kind aforesaid has no utility in reference to a man as a whole. If it be assumed, on the other hand, that the part, A, be checked so that the remaining parts prevail, it may be proved in the same manner that desire arising from pain has no utility in respect to a man as a whole. Q.E.D.

Note.—As pleasure is generally (IV. xliv. note) attributed to one part of the body, we generally desire to preserve our being with out taking into consideration our health as a whole: to which it may be added, that the desires which have most hold over us (IV. ix.) take account of the present and not of the future.

PROP. LXI. Desire which springs from reason cannot be excessive.

Proof.—Desire (Def. of the Emotions, i.) considered absolutely is the actual essence of man, in so far as it is conceived as in any way determined to a particular activity by some given modification of itself. Hence desire, which arises from reason, that is (III. iii.), which is engendered in us in so far as we act, is the actual essence or nature of man, in so far as it is conceived as determined to such activities as are adequately conceived through man's essence only (III. Def. ii.). Now, if such desire could be excessive, human nature considered in itself alone would be able to exceed itself, or would be able to do more than it can, a manifest contradiction. Therefore, such desire cannot be excessive. Q.E.D.

PROP. LXII. In so far as the mind conceives a thing under the dictates of reason, it is affected equally, whether the idea be of a thing future, past, or present.

Proof.—Whatsoever the mind conceives under the guidance of reason, it conceives under the form of eternity or necessity (II. xliv. Coroll. ii.), and is therefore affected with the same certitude (II. xliii. and note). Wherefore, whether the thing be present, past, or future, the mind conceives it under the same necessity and is affected with the same certitude; and whether the idea be of something present, past, or future, it will in all cases be equally true (II. xli.); that is, it will always possess the same properties of an adequate idea (II. Def. iv.); therefore, in so far as the mind conceives things under the dictates of reason, it is affected in the same manner, whether the idea be of a thing future, past, or present. Q.E.D.

Note.—If we could possess an adequate knowledge of the duration of things, and could determine by reason their periods of existence, we should contemplate things future with the same emotion as things present; and the mind would desire as though it were present the good which it conceived as future; consequently it would necessarily neglect a lesser good in the present for the sake of a greater good in the future, and would in no wise desire that which is good in the present but a source of evil in the future, as we shall presently show. However, we can have but a very inadequate knowledge of the duration of things (II. xxxi.); and the periods of their existence (II. xliv. note.) we can only determine by imagination, which is not so powerfully affected by the future as by the present. Hence such true knowledge of good and evil as we possess is merely abstract or general, and the judgment which we pass on the order of things and the connection of causes, with a view to determining what is good or bad for us in the present, is rather imaginary than real. Therefore it is nothing wonderful, if the desire arising from such knowledge of good and evil, in so far as it looks on into the future, be more readily checked than the desire of things which are agreeable at the present time. (Cf. IV. xvi.)

PROP. LXIII. He who is led by fear, and does good in order to escape evil, is not led by reason.

Proof.—All the emotions which are attributable to the mind as active, or in other words to reason, are emotions of pleasure and desire (III. lix.); therefore, he who is led by fear, and does good in order to escape evil, is not led by reason.

Note.—Superstitions persons, who know better how to rail at vice than how to teach virtue, and who strive not to guide men by reason, but so to restrain them that they would rather escape evil than love virtue, have no other aim but to make others as wretched as themselves; wherefore it is nothing wonderful, if they be generally troublesome and odious to their fellow—men.

Corollary.—Under desire which springs from reason, we seek good directly, and shun evil indirectly.

Proof.—Desire which springs from reason can only spring from a pleasurable emotion, wherein the mind is not passive (III. lix.), in other words, from a pleasure which cannot be excessive (IV. lxi.), and not from pain; wherefore this desire springs from the knowledge of good, not of evil (IV. viii.); hence under the guidance of reason we seek good directly and only by implication shun evil. Q.E.D.

Note.—This Corollary may be illustrated by the example of a sick and a healthy man. The sick man through fear of death eats what he naturally shrinks from, but the healthy man takes pleasure in his food, and thus gets a better enjoyment out of life, than if he were in fear of death, and desired directly to avoid it. So a judge, who condemns a criminal to death, not from hatred or anger but from love of the public well—being, is guided solely by reason.

PROP. LXIV. The knowledge of evil is an inadequate knowledge.

Proof.—The knowledge of evil (IV. viii.) is pain, in so far as we are conscious thereof. Now pain is the transition to a lesser perfection (Def. of the Emotions, iii.) and therefore cannot be understood through man's nature (III. vi., and vii.); therefore it is a passive state (III. Def. ii.) which (III. iii.) depends on inadequate ideas; consequently the knowledge thereof (II. xxix.), namely, the knowledge of evil, is inadequate. Q.E.D.

Corollary.—Hence it follows that, if the human mind possessed only adequate ideas, it would form no conception of evil.

PROP. LXV. Under the guidance of reason we should pursue the greater of two goods and the lesser of two evils.

Proof.—A good which prevents our enjoyment of a greater good is in reality an evil; for we apply the terms good and bad to things, in so far as we compare them one with another (see preface to this Part); therefore, evil is in reality a lesser good; hence under the guidance of reason we seek or pursue only the greater good and the lesser evil. Q.E.D.

Corollary.—We may, under the guidance of reason, pursue the lesser evil as though it were the greater good, and we may shun the lesser good, which would be the cause of the greater evil. For the evil, which is here called the lesser, is really good, and the lesser good is really evil, wherefore we may seek the former and shun the latter. Q.E.D.

PROP. LXVI. We may, under the guidance of reason, seek a greater good in the future in preference to a lesser good in the present, and we may seek a lesser evil in the present in preference to a greater evil in the future.[15]

[15] "Maltim praesens minus prae majori futuro." (Van Vloten). Bruder reads: "Malum praesens minus, quod causa est faturi alicujus mali." The last word of the latter is an obvious misprint, and is corrected by the Dutch translator into "majoris boni." (Pollock, p. 268, note.)

Proof.—If the mind could have an adequate knowledge of things future, it would be affected towards what is future in the same way as towards what is present (IV. lxii.); wherefore, looking merely to reason, as in this proposition we are assumed to do, there is no difference, whether the greater good or evil be assumed as present, or assumed as future; hence (IV. lxv.) we may seek a greater good in the future in preference to a lesser good in the present, &c. Q.E.D.

Corollary.—We may, under the guidance of reason, seek a lesser evil in the present, because it is the cause of a greater good in the future, and we may shun a lesser good in the present, because it is the cause of a greater evil in the future. This Corollary is related to the foregoing Proposition as the Corollary to IV. lxv. is related to the said IV. lxv.

Note.—If these statements be compared with what we have pointed out concerning the strength of the emotions in this Part up to Prop. xviii., we shall readily see the difference between a man, who is led solely by emotion or opinion, and a man, who is led by reason. The former, whether will or no, performs actions whereof he is utterly ignorant; the latter is his own master and only performs such actions, as he knows are of primary importance in life, and therefore chiefly desires; wherefore I call the former a slave, and the latter a free man, concerning whose disposition and manner of life it will be well to make a few observations.

PROP. LXVII. A free man thinks of death least of all things; and his wisdom is a meditation not of death but of life.

Proof.—A free man is one who lives under the guidance of reason, who is not led by fear (IV. lxiii.), but who directly desires that which is good (IV. lxiii. Coroll.), in other words (IV. xxiv.), who strives to act, to live, and to preserve his being on the basis of seeking his own true advantage; wherefore such an one thinks of nothing less than of death, but his wisdom is a meditation of life. Q.E.D.

PROP. LXVIII. If men were born free, they would, so long as they remained free, form no conception of good and evil.

Proof.—I call free him who is led solely by reason; he, therefore, who is born free, and who remains free, has only adequate ideas; therefore (IV. lxiv. Coroll.) he has no conception of evil, or consequently (good and evil being correlative) of good. Q.E.D.

Note.—It is evident, from IV. iv., that the hypothesis of this Proposition is false and inconceivable, except in so far as we look solely to the nature of man, or rather to God; not in so far as the latter is infinite, but only in so far as he is the cause of man's existence.

This, and other matters which we have already proved, seem to have been signifieded by Moses in the history of the first man. For in that narrative no other power of God is conceived, save that whereby he created man, that is the power wherewith he provided solely for man's advantage; it is stated that God forbade man, being free, to eat of the tree of the knowledge of good and evil, and that, as soon as man should have eaten of it, he would straightway fear death rather than desire to live. Further, it is written that when man had found a wife, who was in entire harmony with his nature, he knew that there could be nothing in nature which could be more useful to him; but that after he believed the beasts to be like himself, he straightway began to imitate their emotions (III. xxvii.), and to lose his freedom; this freedom was afterwards recovered by the patriarchs, led by the spirit of Christ; that is, by the idea of God, whereon alone it depends, that man may be free, and desire for others the good which he desires for himself, as we have shown above (IV. xxxvii.).

PROP. LXIX. The virtue of a free man is seen to be as great, when it declines dangers, as when it overcomes them.

Proof.—Emotion can only be checked or removed by an emotion contrary to itself, and possessing more power in restraining emotion (IV. vii.). But blind daring and fear are emotions, which can be conceived as equally great (IV. v. and iii.): hence, no less virtue or firmness is required in checking daring than in checking fear (III. lix. note); in other words (Def. of the Emotions, xl. and xli.), the free man shows as much virtue, when he declines dangers, as when he strives to overcome them. Q.E.D.

Corollary.—The free man is as courageous in timely retreat as in combat; or, a free man shows equal courage or presence of mind, whether he elect to give battle or to retreat.

Note.—What courage (animositas) is, and what I mean thereby, I explained in III. lix. note. By danger I mean everything, which can give rise to any evil, such as pain, hatred, discord, &c.

PROP. LXX. The free man, who lives among the ignorant, strives, as far as he can, to avoid receiving favours from them.

Proof.—Everyone judges what is good according to his disposition (III. xxxix. note); wherefore an ignorant man, who has conferred a benefit on another, puts his own estimate upon it, and, if it appears to be estimated less highly by the receiver, will feel pain (III. xlii.). But the free man only desires to join other men to him in friendship (IV. xxxvii.), not repaying their benefits with others reckoned as of like value, but guiding himself and others by the free decision of reason, and doing only such things as he knows to be of primary importance. Therefore the free man, lest he should become hateful to the ignorant, or follow their desires rather than reason, will endeavour, as far as he can, to avoid receiving their favours.

Note.—I say, as far as he can. For though men be ignorant, yet are they men, and in cases of necessity could afford us human aid, the most excellent of all things: therefore it is often necessary to accept favours from them, and consequently to repay such favours in kind; we must, therefore, exercise caution in declining favours, lest we should have the appearance of despising those who bestow them, or of being, from avaricious motives, unwilling to requite them, and so give ground for offence by the very fact of striving to avoid it. Thus, in declining favours, we must look to the requirements of utility and courtesy.

PROP. LXXI. Only free men are thoroughly grateful one to another.

Proof.—Only free men are thoroughly useful one to another, and associated among themselves by the closest necessity of friendship (IV. xxxv., and Coroll. i.), only such men endeavour, with mutual zeal of love, to confer benefits on each other (IV. xxxvii.), and, therefore, only they are thoroughly grateful one to another. Q.E.D.

Note.—The goodwill, which men who are led by blind desire have for one another, is generally a bargaining or enticement, rather than pure goodwill. Moreover, ingratitude is not an emotion. Yet it is base, inasmuch as it generally shows, that a man is affected by excessive hatred, anger, pride, avarice, &c. He who, by reason of his folly, knows not how to return benefits, is not ungrateful, much less he who is not gained over by the gifts of a courtesan to serve her lust, or by a thief to conceal his thefts, or by any similar persons. Contrariwise, such an one shows a constant mind, inasmuch as he cannot by any gifts be corrupted, to his own or the general hurt.

PROP. LXXII. The free man never acts fraudulently, but always in good faith.

Proof.—If it be asked: What should a man's conduct be in a case where he could by breaking faith free himself from the danger of present death? Would not his plan of self—preservation completely persuade him to deceive? This may be answered by pointing out that, if reason persuaded him to act thus, it would persuade all men to act in a similar manner, in which case reason would persuade men not to agree in good faith to unite their forces, or to have laws in common, that is, not to have any general laws, which is absurd.

PROP. LXXIII. The man, who is guided by reason, is more free in a State, where he lives under a general system of law, than in solitude, where he is independent.

Proof.—The man, who is guided by reason, does not obey through fear (IV. lxiii.): but, in so far as he endeavours to preserve his being according to the dictates of reason, that is (IV. lxvi. note), in so far as he endeavours to live in freedom, he desires to order his life according to the general good (IV. xxxvii.), and, consequently (as we showed in IV. xxxvii. note. ii.), to live according to the laws of his country. Therefore the free man, in order to enjoy greater freedom, desires to possess the general rights of citizenship. Q.E.D.

Note.—These and similar observations, which we have made on man's true freedom, may be referred to strength, that is, to courage and nobility of character (III. lix. note). I do not think it worth while to prove separately all the properties of strength; much less need I show, that he that is strong hates no man, is angry with no man, envies no man, is indignant with no man, despises no man, and least of all things is proud. These propositions, and all that relate to the true way of life and religion, are easily proved from IV. xxxvii. and IV. xlvi.; namely, that hatred should be overcome with love, and that every man should desire for others the good which he seeks for himself. We may also repeat what we drew attention to in the note to IV. l., and in other places; namely, that the strong man has ever first in his thoughts, that all things follow from the necessity of the divine nature; so that whatsoever he deems to be hurtful and evil, and whatsoever, accordingly, seems to him impious, horrible, unjust, and base, assumes that appearance owing to his own disordered, fragmentary, and confused view of the universe. Wherefore he strives before all things to conceive things as they really are, and to remove the hindrances to true knowledge, such as are hatred, anger, envy, derision, pride, and similar emotions, which I have mentioned above. Thus he endeavours, as we said before, as far as in him lies, to do good, and to go on his way rejoicing. How far human virtue is capable of attaining to such a condition, and what its powers may be, I will prove in the following Part.

APPENDIX.

What have said in this Part concerning the right way of life has not been arranged, so as to admit of being seen at one view, but has been set forth piece—meal, according as I thought each Proposition could most readily be deduced from what preceded it. I propose, therefore, to rearrange my remarks and to bring them under leading heads.

I. All our endeavours or desires so follow from the necessity of our nature, that they can be understood either through it alone, as their proximate cause, or by virtue of our being a part of nature, which cannot be adequately conceived through itself without other individuals.

II. Desires, which follow from our nature in such a manner, that they can be understood through it alone, are those which are referred to the mind, in so far as the latter is conceived to consist of adequate ideas: the remaining desires are only referred to the mind, in so far as it conceives things inadequately, and their force and increase are generally defined not by the power of man, but by the power of things external to us: wherefore the former are rightly called actions, the latter passions, for the former always indicate our power, the latter, on the other hand, show our infirmity and fragmentary knowledge.

III. Our actions, that is, those desires which are defined by man's power or reason, are always good. The rest may be either good or bad.

IV. Thus in life it is before all things useful to perfect the understanding, or reason, as far as we can, and in this alone man's highest happiness or blessedness consists, indeed blessedness is nothing else but the contentment of spirit, which arises from the intuitive knowledge of God: now, to perfect the understanding is nothing else but to understand God, God's attributes, and the actions which follow from the necessity of his nature. Wherefore of a man, who is led by reason, the ultimate aim or highest desire, whereby he seeks to govern all his fellows, is that whereby he is brought to the adequate conception of himself and of all things within the scope of his intelligence.

V. Therefore, without intelligence there is not rational life: and things are only good, in so far as they aid man in his enjoyment of the intellectual life, which is defined by intelligence. Contrariwise, whatsoever things hinder man's perfecting of his reason, and capability to enjoy the rational life, are alone called evil.

VI. As all things whereof man is the efficient cause are necessarily good, no evil can befall man except through external causes; namely, by virtue of man being a part of universal nature, whose laws human nature is compelled to obey, and to conform to in almost infinite ways.

VII. It is impossible, that man should not be a part of nature, or that he should not follow her general order; but if he be thrown among individuals whose nature is in harmony with his own, his power of action will thereby be aided and fostered, whereas, if he be thrown among such as are but very little in harmony with his nature, he will hardly be able to accommodate himself to them without undergoing a great change himself.

VIII. Whatsoever in nature we deem to be evil, or to be capable of injuring our faculty for existing and enjoying the rational life, we may endeavour to remove in whatever way seems safest to us; on the other hand, whatsoever we deem to be good or useful for preserving our being, and enabling us to enjoy the rational life, we may appropriate to our use and employ as we think best. Everyone without exception may, by sovereign right of nature, do whatsoever he thinks will advance his own interest.

IX. Nothing can be in more harmony with the nature of any given thing than other individuals of the same species; therefore (cf. vii.) for man in the preservation of his being and the enjoyment of the rational life there is nothing more useful than his fellow—man who is led by reason. Further, as we know not anything among individual things which is more excellent than a man led by reason, no man can better display the power of his skill and disposition, than in so training men, that they come at last to live under the dominion of their own reason.

X. In so far as men are influenced by envy or any kind of hatred, one towards another, they are at variance, and are therefore to be feared in proportion, as they are more powerful than their fellows.

XI. Yet minds are not conquered by force, but by love and high—mindedness.

XII. It is before all things useful to men to associate their ways of life, to bind themselves together with such bonds as they think most fitted to gather them all into unity, and generally to do whatsoever serves to strengthen friendship.

XIII. But for this there is need of skill and watchfulness. For men are diverse (seeing that those who live under the guidance of reason are few), yet are they generally envious and more prone to revenge than to sympathy. No small force of character is therefore required to take everyone as he is, and to restrain one's self from imitating the emotions of others. But those who carp at mankind, and are more skilled in railing at vice than in instilling virtue, and who break rather than strengthen men's dispositions, are hurtful both to themselves and others. Thus many from too great impatience of spirit, or from misguided religious zeal, have preferred to live among brutes rather than among men; as boys or youths, who cannot peaceably endure the chidings of their parents, will enlist as soldiers and choose the hardships of war and the despotic discipline in preference to the comforts of home and the admonitions of their father: suffering any burden to be put upon them, so long as they may spite their parents.

XIV. Therefore, although men are generally governed in everything by their own lusts, yet their association in common brings many more advantages than drawbacks. Wherefore it is better to bear patiently the wrongs they may do us, and to strive to promote whatsoever serves to bring about harmony and friendship.

XV. Those things, which beget harmony, are such as are attributable to justice, equity, and honourable living. For men brook ill not only what is unjust or iniquitous, but also what is reckoned disgraceful, or that a man should slight the received customs of their society. For winning love those qualities are especially necessary which have regard to religion and piety (cf. IV. xxxvii. notes. i. ii.; xlvi. note; and lxxiii. note).

XVI. Further, harmony is often the result of fear: but such harmony is insecure. Further, fear arises from infirmity of spirit, and moreover belongs not to the exercise of reason: the same is true of compassion, though this latter seems to bear a certain resemblance to piety.

XVII. Men are also gained over by liberality, especially such as have not the means to buy what is necessary to sustain life. However, to give aid to every poor man is far beyond the power and the advantage of any private person. For the riches of any private person are wholly inadequate to meet such a call. Again, an individual man's resources of character are too limited for him to be able to make all men his friends. Hence providing for the poor is a duty, which falls on the State as a whole, and has regard only to the general advantage.

XVIII. In accepting favours, and in returning gratitude our duty must be wholly different (cf. IV. lxx. note; lxxi. note).

XIX. Again, meretricious love, that is, the lust of generation arising from bodily beauty, and generally every sort of love, which owns anything save freedom of soul as its cause, readily passes into hate; unless indeed, what is worse, it is a species of madness; and then it promotes discord rather than harmony (cf. III. xxxi. Coroll.).

XX. As concerning marriage, it is certain that this is in harmony with reason, if the desire for physical union be not engendered solely by bodily beauty, but also by the desire to beget children and to train them up wisely; and moreover, if the love of both, to wit, of the man and of the woman, is not caused by bodily beauty only, but also by freedom of soul.

XXI. Furthermore, flattery begets harmony; but only by means of the vile offence of slavishness or treachery. None are more readily taken with flattery than the proud, who wish to be first, but are not.

XXII. There is in abasement a spurious appearance of piety and religion. Although abasement is the opposite to pride, yet is he that abases himself most akin to the proud (IV. lvii. note).

XXIII. Shame also brings about harmony, but only in such matters as cannot be hid. Further, as shame is a species of pain, it does not concern the exercise of reason.

XXIV. The remaining emotions of pain towards men are directly opposed to justice, equity, honour, piety, and religion; and, although indignation seems to bear a certain resemblance to equity, yet is life but lawless, where every man may pass judgment on another's deeds, and vindicate his own or other men's rights.

XXV. Correctness of conduct (modestia), that is, the desire of pleasing men which is determined by reason, is attributable to piety (as we said in IV. xxxvii. note. i.). But, if it spring from emotion, it is ambition, or the desire whereby, men, under the false cloak of piety, generally stir up discords and seditions. For he who desires to aid his fellows either in word or in deed, so that they may together enjoy the highest good, he, I say, will before all things strive to win them over with love: not to draw them into admiration, so that a system may be called after his name, nor to give any cause for envy. Further, in his conversation he will shrink from talking of men's faults, and will be careful to speak but sparingly of human infirmity: but he will dwell at length on human virtue or power, and the way whereby it may be perfected. Thus will men be stirred not by fear, nor by aversion, but only by the emotion of joy, to endeavour, so far as in them lies, to live in obedience to reason.

XXVI. Besides men, we know of no particular thing in nature in whose mind we may rejoice, and whom we can associate with ourselves in friendship or any sort of fellowship; therefore, whatsoever there be in nature besides man, a regard for our advantage does not call on us to preserve, but to preserve or destroy according to its various capabilities, and to adapt to our use as best we may.

XXVII. The advantage which we derive from things external to us, besides the experience and knowledge which we acquire from observing them, and from recombining their elements in different forms, is principally the preservation of the body; from this point of view, those things are most useful which can so feed and nourish the body, that all its parts may rightly fulfil their functions. For, in proportion as the body is capable of being affected in a greater variety of ways, and of affecting external bodies in a great number of ways, so much the more is the mind capable of thinking (IV. xxxviii., xxxix.). But there seem to be very few things of this kind in nature; wherefore for the due nourishment of the body we must use many foods of diverse nature. For the human body is composed of very many parts of different nature, which stand in continual need of varied nourishment, so that the whole body may be equally capable of doing everything that can follow from its own nature, and consequently that the mind also may be equally capable of forming many perceptions.

XXVIII. Now for providing these nourishments the strength of each individual would hardly suffice, if men did not lend one another mutual aid. But money has furnished us with a token for everything: hence it is with the notion of money, that the mind of the multitude is chiefly engrossed: nay, it can hardly conceive any kind of pleasure, which is not accompanied with the idea of money as cause.

XXIX. This result is the fault only of those, who seek money, not from poverty or to supply their necessary wants, but because they have learned the arts of gain, wherewith they bring themselves to great splendour. Certainly they nourish their bodies, according to custom, but scantily, believing that they lose as much of their wealth as they spend on the preservation of their body. But they who know the true use of money, and who fix the measure of wealth solely with regard to their actual needs, live content with little.

XXX. As, therefore, those things are good which assist the various parts of the body, and enable them to perform their functions; and as pleasure consists in an increase of, or aid to, man's power, in so far as he is composed of mind and body; it follows that all those things which bring pleasure are good. But seeing that things do not work with the object of giving us pleasure, and that their power of action is not tempered to suit our advantage, and, lastly, that pleasure is generally referred to one part of the body more than to the other parts; therefore most emotions of pleasure (unless reason and watchfulness be at hand), and consequently the desires arising therefrom, may become excessive. Moreover we may add that emotion leads us to pay most regard to what is agreeable in the present, nor can we estimate what is future with emotions equally vivid. (IV. xliv. note, and lx. note.)

XXXI. Superstition, on the other hand, seems to account as good all that brings pain, and as bad all that brings pleasure. However, as we said above (IV. xlv. note), none but the envious take delight in my infirmity and trouble. For the greater the pleasure whereby we are affected, the greater is the perfection whereto we pass, and consequently the more do we partake of the divine nature: no pleasure can ever be evil, which is regulated by a true regard for our advantage. But contrariwise he, who is led by fear and does good only to avoid evil, is not guided by reason.

XXXII. But human power is extremely limited, and is infinitely surpassed by the power of external causes; we have not, therefore, an absolute power of shaping to our use those things which are without us. Nevertheless, we shall bear with an equal mind all that happens to us in contravention to the claims of our own advantage, so long as we are conscious, that we have done our duty, and that the power which we possess is not sufficient to enable us to protect ourselves completely; remembering that we are a part of universal nature, and that we follow her order. If we have a clear and distinct understanding of this, that part of our nature which is defined by intelligence, in other words the better part of ourselves, will assuredly acquiesce in what befalls us, and in such acquiescence will endeavour to persist. For, in so far as we are intelligent beings, we cannot desire anything save that which is necessary, nor yield absolute acquiescence to anything, save to that which is true: wherefore, in so far as we have a right understanding of these things, the endeavour of the better part of ourselves is in harmony with the order of nature as a whole.



PART V:

Of the Power of the Understanding, or of Human Freedom

PREFACE



At length I pass to the remaining portion of my Ethics, which is concerned with the way leading to freedom. I shall therefore treat therein of the power of the reason, showing how far the reason can control the emotions, and what is the nature of Mental Freedom or Blessedness; we shall then be able to see, how much more powerful the wise man is than the ignorant. It is no part of my design to point out the method and means whereby the understanding may be perfected, nor to show the skill whereby the body may be so tended, as to be capable of the due performance of its functions. The latter question lies in the province of Medicine, the former in the province of Logic. Here, therefore, I repeat, I shall treat only of the power of the mind, or of reason; and I shall mainly show the extent and nature of its dominion over the emotions, for their control and moderation. That we do not possess absolute dominion over them, I have already shown. Yet the Stoics have thought, that the emotions depended absolutely on our will, and that we could absolutely govern them. But these philosophers were compelled, by the protest of experience, not from their own principles, to confess, that no slight practice and zeal is needed to control and moderate them: and this someone endeavoured to illustrate by the example (if I remember rightly) of two dogs, the one a house—dog and the other a hunting—dog. For by long training it could be brought about, that the house—dog should become accustomed to hunt, and the hunting—dog to cease from running after hares. To this opinion Descartes not a little inclines. For he maintained, that the soul or mind is specially united to a particular part of the brain, namely, to that part called the pineal gland, by the aid of which the mind is enabled to feel all the movements which are set going in the body, and also external objects, and which the mind by a simple act of volition can put in motion in various ways. He asserted, that this gland is so suspended in the midst of the brain, that it could be moved by the slightest motion of the animal spirits: further, that this gland is suspended in the midst of the brain in as many different manners, as the animal spirits can impinge thereon; and, again, that as many different marks are impressed on the said gland, as there are different external objects which impel the animal spirits towards it; whence it follows, that if the will of the soul suspends the gland in a position, wherein it has already been suspended once before by the animal spirits driven in one way or another, the gland in its turn reacts on the said spirits, driving and determining them to the condition wherein they were, when repulsed before by a similar position of the gland. He further asserted, that every act of mental volition is united in nature to a certain given motion of the gland. For instance, whenever anyone desires to look at a remote object, the act of volition causes the pupil of the eye to dilate, whereas, if the person in question had only thought of the dilatation of the pupil, the mere wish to dilate it would not have brought about the result, inasmuch as the motion of the gland, which serves to impel the animal spirits towards the optic nerve in a way which would dilate or contract the pupil, is not associated in nature with the wish to dilate or contract the pupil, but with the wish to look at remote or very near objects. Lastly, he maintained that, although every motion of the aforesaid gland seems to have been united by nature to one particular thought out of the whole number of our thoughts from the very beginning of our life, yet it can nevertheless become through habituation associated with other thoughts; this he endeavours to prove in the Passions de l'ame, I.50. He thence concludes, that there is no soul so weak, that it cannot, under proper direction, acquire absolute power over its passions. For passions as defined by him are "perceptions, or feelings, or disturbances of the soul, which are referred to the soul as species, and which (mark the expression) are produced, preserved, and strengthened through some movement of the spirits." (Passions de l'ame, I.27). But, seeing that we can join any motion of the gland, or consequently of the spirits, to any volition, the determination of the will depends entirely on our own powers; if, therefore, we determine our will with sure and firm decisions in the direction to which we wish our actions to tend, and associate the motions of the passions which we wish to acquire with the said decisions, we shall acquire an absolute dominion over our passions. Such is the doctrine of this illustrious philosopher (in so far as I gather it from his own words); it is one which, had it been less ingenious, I could hardly believe to have proceeded from so great a man. Indeed, I am lost in wonder, that a philosopher, who had stoutly asserted, that he would draw no conclusions which do not follow from self—evident premisses, and would affirm nothing which he did not clearly and distinctly perceive, and who had so often taken to task the scholastics for wishing to explain obscurities through occult qualities, could maintain a hypothesis, beside which occult qualities are commonplace. What does he understand, I ask, by the union of the mind and the body? What clear and distinct conception has he got of thought in most intimate union with a certain particle of extended matter? Truly I should like him to explain this union through its proximate cause. But he had so distinct a conception of mind being distinct from body, that he could not assign any particular cause of the union between the two, or of the mind itself, but was obliged to have recourse to the cause of the whole universe, that is to God. Further, I should much like to know, what degree of motion the mind can impart to this pineal gland, and with what force can it hold it suspended? For I am in ignorance, whether this gland can be agitated more slowly or more quickly by the mind than by the animal spirits, and whether the motions of the passions, which we have closely united with firm decisions, cannot be again disjoined therefrom by physical causes; in which case it would follow that, although the mind firmly intended to face a given danger, and had united to this decision the motions of boldness, yet at the sight of the danger the gland might become suspended in a way, which would preclude the mind thinking of anything except running away. In truth, as there is no common standard of volition and motion, so is there no comparison possible between the powers of the mind and the power or strength of the body; consequently the strength of one cannot in any wise be determined by the strength of the other. We may also add, that there is no gland discoverable in the midst of the brain, so placed that it can thus easily be set in motion in so many ways, and also that all the nerves are not prolonged so far as the cavities of the brain. Lastly, I omit all the assertions which he makes concerning the will and its freedom, inasmuch as I have abundantly proved that his premisses are false. Therefore, since the power of the mind, as I have shown above, is defined by the understanding only, we shall determine solely by the knowledge of the mind the remedies against the emotions, which I believe all have had experience of, but do not accurately observe or distinctly see, and from the same basis we shall deduce all those conclusions, which have regard to the mind's blessedness.

AXIOMS.

I. If two contrary actions be started in the same subject, a change must necessarily take place, either in both, or in one of the two, and continue until they cease to be contrary.

II. The power of an effect is defined by the power of its cause, in so far as its essence is explained or defined by the essence of its cause.

(This axiom is evident from III. vii.)

PROPOSITIONS.

PROP. I. Even as thoughts and the ideas of things are arranged and associated in the mind, so are the modifications of body or the images of things precisely in the same way arranged and associated in the body.

Proof.—The order and connection of ideas is the same (II. vii.) as the order and connection of things, and vice versa the order and connection of things is the same (II. vi. Coroll. and vii.) as the order and connection of ideas. Wherefore, even as the order and connection of ideas in the mind takes place according to the order and association of modifications of the body (II. xviii.), so vice versa (III. ii.) the order and connection of modifications of the body takes place in accordance with the manner, in which thoughts and the ideas of things are arranged and associated in the mind. Q.E.D.

PROP. II. If we remove a disturbance of the spirit, or emotion, from the thought of an external cause, and unite it to other thoughts, then will the love or hatred towards that external cause, and also the vacillations of spirit which arise from these emotions, be destroyed.

Proof.—That, which constitutes the reality of love or hatred, is pleasure or pain, accompanied by the idea of an external cause (Def. of the Emotions, vi. vii.); wherefore, when this cause is removed, the reality of love or hatred is removed with it; therefore these emotions and those which arise therefrom are destroyed. Q.E.D.

PROP. III. An emotion, which is a passion, ceases to be a passion, as soon as we form a clear and distinct idea thereof.

Proof.—An emotion, which is a passion, is a confused idea (by the general Def. of the Emotions). If, therefore, we form a clear and distinct idea of a given emotion, that idea will only be distinguished from the emotion, in so far as it is referred to the mind only, by reason (II. xxi., and note); therefore (III. iii.), the emotion will cease to be a passion. Q.E.D.

Corollary—An emotion therefore becomes more under our control, and the mind is less passive in respect to it, in proportion as it is more known to us.

PROP. IV. There is no modification of the body, whereof we cannot form some clear and distinct conception.

Proof.—Properties which are common to all things can only be conceived adequately (II. xxxviii.); therefore (II. xii. and Lemma ii. after II. xiii.) there is no modification of the body, whereof we cannot form some clear and distinct conception. Q.E.D.

Corollary.—Hence it follows that there is no emotion, whereof we cannot form some clear and distinct conception. For an emotion is the idea of a modification of the body (by the general Def. of the Emotions), and must therefore (by the preceding Prop.) involve some clear and distinct conception.

Note.—Seeing that there is nothing which is not followed by an effect (I. xxxvi.), and that we clearly and distinctly understand whatever follows from an idea, which in us is adequate (II. xl.), it follows that everyone has the power of clearly and distinctly understanding himself and his emotions, if not absolutely, at any rate in part, and consequently of bringing it about, that he should become less subject to them. To attain this result, therefore, we must chiefly direct our efforts to acquiring, as far as possible, a clear and distinct knowledge of every emotion, in order that the mind may thus, through emotion, be determined to think of those things which it clearly and distinctly perceives, and wherein it fully acquiesces: and thus that the emotion itself may be separated from the thought of an external cause, and may be associated with true thoughts; whence it will come to pass, not only that love, hatred, &c. will be destroyed (V. ii.), but also that the appetites or desires, which are wont to arise from such emotion, will become incapable of being excessive (IV. lxi.). For it must be especially remarked, that the appetite through which a man is said to be active, and that through which he is said to be passive is one and the same. For instance, we have shown that human nature is so constituted, that everyone desires his fellow—men to live after his own fashion (III. xxxi. note); in a man, who is not guided by reason, this appetite is a passion which is called ambition, and does not greatly differ from pride; whereas in a man, who lives by the dictates of reason, it is an activity or virtue which is called piety (IV. xxxvii. note. i. and second proof). In like manner all appetites or desires are only passions, in so far as they spring from inadequate ideas; the same results are accredited to virtue, when they are aroused or generated by adequate ideas. For all desires, whereby we are determined to any given action, may arise as much from adequate as from inadequate ideas (IV. lix.). Than this remedy for the emotions (to return to the point from which I started), which consists in a true knowledge thereof, nothing more excellent, being within our power, can be devised. For the mind has no other power save that of thinking and of forming adequate ideas, as we have shown above (III. iii.).

PROP. V. An emotion towards a thing, which we conceive simply, and not as necessary, or as contingent, or as possible, is, other conditions being equal, greater than any other emotion.

Proof.—An emotion towards a thing, which we conceive to be free, is greater than one towards what we conceive to be necessary (III. xlix.), and, consequently, still greater than one towards what we conceive as possible, or contingent (IV. xi.). But to conceive a thing as free can be nothing else than to conceive it simply, while we are in ignorance of the causes whereby it has been determined to action (II. xxxv. note); therefore, an emotion towards a thing which we conceive simply is, other conditions being equal, greater than one, which we feel towards what is necessary, possible, or contingent, and, consequently, it is the greatest of all. Q.E.D.

PROP. VI. The mind has greater power over the emotions and is less subject thereto, in so far as it understands all things as necessary.

Proof.—The mind understands all things to be necessary (I. xxix.) and to be determined to existence and operation by an infinite chain of causes; therefore (by the foregoing Proposition), it thus far brings it about, that it is less subject to the emotions arising therefrom, and (III. xlviii.) feels less emotion towards the things themselves. Q.E.D.

Note.—The more this knowledge, that things are necessary, is applied to particular things, which we conceive more distinctly and vividly, the greater is the power of the mind over the emotions, as experience also testifies. For we see, that the pain arising from the loss of any good is mitigated, as soon as the man who has lost it perceives, that it could not by any means have been preserved. So also we see that no one pities an infant, because it cannot speak, walk, or reason, or lastly, because it passes so many years, as it were, in unconsciousness. Whereas, if most people were born full—grown and only one here and there as an infant, everyone would pity the infants; because infancy would not then be looked on as a state natural and necessary, but as a fault or delinquency in Nature; and we may note several other instances of the same sort.

PROP. VII. Emotions which are aroused or spring from reason, if we take account of time, are stronger than those, which are attributable to particular objects that we regard as absent.

Proof.—We do not regard a thing as absent, by reason of the emotion wherewith we conceive it, but by reason of the body, being affected by another emotion excluding the existence of the said thing (II. xvii.). Wherefore, the emotion, which is referred to the thing which we regard as absent, is not of a nature to overcome the rest of a man's activities and power (IV. vi.), but is, on the contrary, of a nature to be in some sort controlled by the emotions, which exclude the existence of its external cause (IV. ix.). But an emotion which springs from reason is necessarily referred to the common properties of things (see the def. of reason in II. xl. note. ii.), which we always regard as present (for there can be nothing to exclude their present existence), and which we always conceive in the same manner (II. xxxviii.). Wherefore an emotion of this kind always remains the same; and consequently (V. Ax. i.) emotions, which are contrary thereto and are not kept going by their external causes, will be obliged to adapt themselves to it more and more, until they are no longer contrary to it; to this extent the emotion which springs from reason is more powerful. Q.E.D.

PROP. VIII. An emotion is stronger in proportion to the number of simultaneous concurrent causes whereby it is aroused.

Proof.—Many simultaneous causes are more powerful than a few (III. vii.): therefore (IV. v.), in proportion to the increased number of simultaneous causes whereby it is aroused, an emotion becomes stronger. Q.E.D.

Note—This proposition is also evident from V. Ax. ii.

PROP. IX. An emotion, which is attributable to many and diverse causes which the mind regards as simultaneous with the emotion itself, is less hurtful, and we are less subject thereto and less affected towards each of its causes, than if it were a different and equally powerful emotion attributable to fewer causes or to a single cause.

Proof.—An emotion is only bad or hurtful, in so far as it hinders the mind from being able to think (IV. xxvi. xxvii.); therefore, an emotion, whereby the mind is determined to the contemplation of several things at once, is less hurtful than another equally powerful emotion, which so engrosses the mind in the single contemplation of a few objects or of one, that it is unable to think of anything else; this was our first point. Again, as the mind's essence, in other words, its power (III. vii.), consists solely in thought (II. xi.), the mind is less passive in respect to an emotion, which causes it to think of several things at once, than in regard to an equally strong emotion, which keeps it engrossed in the contemplation of a few or of a single object: this was our second point. Lastly, this emotion (III. xlviii.), in so far as it is attributable to several causes, is less powerful in regard to each of them. Q.E.D.

PROP. X. So long as we are not assailed by emotions contrary to our nature, we have the power of arranging and associating the modifications of our body according to the intellectual order.

Proof.—The emotions, which are contrary to our nature, that is (IV. xxx.), which are bad, are bad in so far as they impede the mind from understanding (IV. xxvii.). So long, therefore, as we are not assailed by emotions contrary to our nature, the mind's power, whereby it endeavours to understand things (IV. xxvi.), is not impeded, and therefore it is able to form clear and distinct ideas and to deduce them one from another (II. xl. note. ii. and II. xlvii. note); consequently we have in such cases the power of arranging and associating the modifications of the body according to the intellectual order. Q.E.D.

Note.—By this power of rightly arranging and associating the bodily modifications we can guard ourselves from being easily affected by evil emotions. For (V. vii.) a greater force is needed for controlling the emotions, when they are arranged and associated according to the intellectual order, than when they, are uncertain and unsettled. The best we can do, therefore, so long as we do not possess a perfect knowledge of our emotions, is to frame a system of right conduct, or fixed practical precepts, to commit it to memory, and to apply it forthwith[16] to the particular circumstances which now and again meet us in life, so that our imagination may become fully imbued therewith, and that it may be always ready to our hand. For instance, we have laid down among the rules of life (IV. xlvi. and note), that hatred should be overcome with love or high—mindedness, and not required with hatred in return. Now, that this precept of reason may be always ready to our hand in time of need, we should often think over and reflect upon the wrongs generally committed by men, and in what manner and way they may be best warded off by high—mindedness: we shall thus associate the idea of wrong with the idea of this precept, which accordingly will always be ready for use when a wrong is done to us (II. xviii.). If we keep also in readiness the notion of our true advantage, and of the good which follows from mutual friendships, and common fellowships; further, if we remember that complete acquiescence is the result of the right way of life ( IV. lii.), and that men, no less than everything else, act by the necessity of their nature: in such case I say the wrong, or the hatred, which commonly arises therefrom, will engross a very small part of our imagination and will be easily overcome; or, if the anger which springs from a grievous wrong be not overcome easily, it will nevertheless be overcome, though not without a spiritual conflict, far sooner than if we had not thus reflected on the subject beforehand. As is indeed evident from V. vi. vii. viii. We should, in the same way, reflect on courage as a means of overcoming fear; the ordinary dangers of life should frequently be brought to mind and imagined, together with the means whereby through readiness of resource and strength of mind we can avoid and overcome them. But we must note, that in arranging our thoughts and conceptions we should always bear in mind that which is good in every individual thing (IV. lxiii. Coroll. and III. lix.), in order that we may always be determined to action by an emotion of pleasure. For instance, if a man sees that he is too keen in the pursuit of honour, let him think over its right use, the end for which it should be pursued, and the means whereby he may attain it. Let him not think of its misuse, and its emptiness, and the fickleness of mankind, and the like, whereof no man thinks except through a morbidness of disposition; with thoughts like these do the most ambitious most torment themselves, when they despair of gaining the distinctions they hanker after, and in thus giving vent to their anger would fain appear wise. Wherefore it is certain that those, who cry out the loudest against the misuse of honour and the vanity of the world, are those who most greedily covet it. This is not peculiar to the ambitious, but is common to all who are ill—used by fortune, and who are infirm in spirit. For a poor man also, who is miserly, will talk incessantly of the misuse of wealth and of the vices of the rich; whereby he merely torments himself, and shows the world that he is intolerant, not only of his own poverty, but also of other people's riches. So, again, those who have been ill received by a woman they love think of nothing but the inconstancy, treachery, and other stock faults of the fair sex; all of which they consign to oblivion, directly they are again taken into favour by their sweetheart. Thus he who would govern his emotions and appetite solely by the love of freedom strives, as far as he can, to gain a knowledge of the virtues and their causes, and to fill his spirit with the joy which arises from the true knowledge of them: he will in no wise desire to dwell on men's faults, or to carp at his fellows, or to revel in a false show of freedom. Whosoever will diligently observe and practise these precepts (which indeed are not difficult) will verily, in a short space of time, be able, for the most part, to direct his actions according to the commandments of reason.

[16] Continuo. Rendered "constantly" by Mr. Pollock on the ground that the classical meaning of the word does not suit the context.

PROP. XI. In proportion as a mental image is referred to more objects, so is it more frequent, or more often vivid, and occupies the mind more.

Proof.—In proportion as a mental image or an emotion is referred to more objects, so are there more causes whereby it can be aroused and fostered, all of which (by hypothesis) the mind contemplates simultaneously in association with the given emotion; therefore the emotion is more frequent, or is more often in full vigour, and (V. viii.) occupies the mind more. Q.E.D.

PROP. XII. The mental images of things are more easily associated with the images referred to things which we clearly and distinctly understand, than with others.

Proof.—Things, which we clearly and distinctly understand, are either the common properties of things or deductions therefrom (see definition of Reason, II. xl. note ii.), and are consequently (by the last Prop.) more often aroused in us. Wherefore it may more readily happen, that we should contemplate other things in conjunction with these than in conjunction with something else, and consequently (II. xviii.) that the images of the said things should be more often associated with the images of these than with the images of something else. Q.E.D.

PROP. XIII. A mental image is more often vivid, in proportion as it is associated with a greater number of other images.

Proof.—In proportion as an image is associated with a greater number of other images, so (II. xviii.) are there more causes whereby it can be aroused. Q.E.D.

PROP. XIV. The mind can bring it about, that all bodily modifications or images of things may be referred to the idea of God.

Proof.—There is no modification of the body, whereof the mind may not form some clear and distinct conception (V. iv.); wherefore it can bring it about, that they should all be referred to the idea of God (I. xv.). Q.E.D.

PROP. XV. He who clearly and distinctly understands himself and his emotions loves God, and so much the more in proportion as he more understands himself and his emotions.

Proof.—He who clearly and distinctly understands himself and his emotions feels pleasure (III. liii.), and this pleasure is (by the last Prop.) accompanied by the idea of God; therefore (Def. of the Emotions, vi.) such an one loves God, and (for the same reason) so much the more in proportion as he more understands himself and his emotions. Q.E.D.

PROP. XVI. This love towards God must hold the chief place in the mind.

Proof.—For this love is associated with all the modifications of the body (V. xiv.) and is fostered by them all (V. xv.); therefore (V. xi.), it must hold the chief place in the mind. Q.E.D.

PROP. XVII. God is without passions, neither is he affected by any emotion of pleasure or pain.

Proof.—All ideas, in so far as they are referred to God, are true (II. xxxii.), that is (II. Def. iv.) adequate; and therefore (by the general Def. of the Emotions) God is without passions. Again, God cannot pass either to a greater or to a lesser perfection (I. xx. Coroll. ii.); therefore (by Def. of the Emotions, ii. iii.) he is not affected by any emotion of pleasure or pain.

Corollary.—Strictly speaking, God does not love or hate anyone. For God (by the foregoing Prop.) is not affected by any emotion of pleasure or pain, consequently (Def. of the Emotions, vi. vii.) he does not love or hate anyone.

PROP. XVIII. No one can hate God.

Proof.—The idea of God which is in us is adequate and perfect (II. xlvi. xlvii.); wherefore, in so far as we contemplate God, we are active (III. iii.); consequently (III. lix.) there can be no pain accompanied by the idea of God, in other words (Def. of the Emotions, vii.), no one can hate God. Q.E.D.

Corollary.—Love towards God cannot be turned into hate.

Note.—It may be objected that, as we understand God as the cause of all things, we by that very fact regard God as the cause of pain. But I make answer, that, in so far as we understand the causes of pain, it to that extent (V. iii.) ceases to be a passion, that is, it ceases to be pain (III. lix.); therefore, in so far as we understand God to be the cause of pain, we to that extent feel pleasure.

PROP. XIX. He, who loves God, cannot endeavour that God should love him in return.

Proof.—For, if a man should so endeavour, he would desire (V. xvii. Coroll.) that God, whom he loves, should not be God, and consequently he would desire to feel pain (III. xix.); which is absurd (III. xxviii.). Therefore, he who loves God, &c. Q.E.D.

PROP. XX. This love towards God cannot be stained by the emotion of envy or jealousy: contrariwise, it is the more fostered, in proportion as we conceive a greater number of men to be joined to God by the same bond of love.

Proof.—This love towards God is the highest good which we can seek for under the guidance of reason (IV. xxviii.), it is common to all men (IV. xxxvi.), and we desire that all should rejoice therein (IV. xxxvii.); therefore (Def. of the Emotions, xxiii.), it cannot be stained by the emotion envy, nor by the emotion of jealousy (V. xviii. see definition of Jealousy, III. xxxv. note); but, contrariwise, it must needs be the more fostered, in proportion as we conceive a greater number of men to rejoice therein. Q.E.D.

Note.—We can in the same way show, that there is no emotion directly contrary to this love, whereby this love can be destroyed; therefore we may conclude, that this love towards God is the most constant of all the emotions, and that, in so far as it is referred to the body, it cannot be destroyed, unless the body be destroyed also. As to its nature, in so far as it is referred to the mind only, we shall presently inquire.

I have now gone through all the remedies against the emotions, or all that the mind, considered in itself alone, can do against them. Whence it appears that the mind's power over the emotions consists:——
