The Philosophy of Spinoza by Benedictus de Spinoza (e textbook reader .txt) 📕

now to show what it is which reason prescribes to us, which emotions agree with the rules of human reason, and which, on the contrary, are opposed to these rules. Before, however, I begin to demonstrate these things by our full method, I should like briefly to set forth here these dictates of reason, in order that what I have in my mind about them may be easily comprehended by all.

Since reason demands nothing which is opposed to Nature, it demands, therefore, that every person should love himself, should seek his own profit—what is truly profitable to him—should desire everything that really leads man to greater perfection, and absolutely that every one should endeavor, as far as in him lies, to preserve his own being. This is all true as necessarily as that the whole is greater than its part. Again, since virtue means nothing but acting according to the laws of our own nature, and since no one endeavors to preserve his being except in accordance with the laws of his own nature, it follows: Firstly, That the foundation of virtue is that endeavor itself to preserve our own being, and that happiness consists in this—that a man can preserve his own being. Secondly, It follows that virtue is to be desired for its own sake, nor is there anything more excellent or more useful to us than virtue, for the sake of which virtue ought to be desired. Thirdly, It follows that all persons who kill themselves are impotent in mind, and have been thoroughly overcome by external causes opposed to their nature.

Again, we can never free ourselves from the need of something outside us for the preservation of our being, and we can never live in such a manner as to have no intercourse with objects which are outside us. Indeed, so far as the mind is concerned, our intellect would be less perfect if the mind were alone, and understood nothing but itself. There are many things, therefore, outside us which are useful to us, and which, therefore, are to be sought. Of all these, none more excellent can be discovered than those which exactly agree with our nature. If, for example, two individuals of exactly the same nature are joined together, they make up a single individual, doubly stronger than each alone. Nothing, therefore, is more useful to man than man. Men can desire, I say, nothing more excellent for the preservation of their being than that all should so agree at every point that the minds and bodies of all should form, as it were, one mind and one body; that all should together endeavor as much as possible to preserve their being, and that all should together seek the common good of all. From this it follows that men who are governed by reason—that is to say, men who, under the guidance of reason, seek their own profit—desire nothing for themselves which they do not desire for other men, and that, therefore, they are just, faithful, and honorable.

These are those dictates of reason which I purposed briefly to set forth before commencing their demonstration by a fuller method, in order that, if possible, I might win the attention of those who believe that this principle—that every one is bound to seek his own profit—is the foundation of impiety, and not of virtue and piety.

The Essence of Virtue I

According to the laws of his own nature each person necessarily desires that which he considers to be good, and avoids that which he considers to be evil.

The more each person strives and is able to seek his own profit, that is to say, to preserve his being, the more virtue does he possess; on the other hand, in so far as each person neglects his own profit, that is to say, neglects to preserve his own being, is he impotent.

No one, therefore, unless defeated by external causes and those which are contrary to his nature, neglects to seek his own profit or preserve his being. No one, I say, refuses food or kills himself from a necessity of his nature, but only when forced by external causes. The compulsion may be exercised in many ways. A man kills himself under compulsion by another when that other turns the right hand, with which the man had by chance laid hold of a sword, and compels him to direct the sword against his own heart; or the command of a tyrant may compel a man, as it did Seneca, to open his own veins, that is to say, he may desire to avoid a greater evil by a less. External and hidden causes also may so dispose his imagination and may so affect his body as to cause it to put on another nature contrary to that which it had at first, and one whose idea cannot exist in the mind; but a very little reflection will show that it is as impossible that a man, from the necessity of his nature, should endeavor not to exist, or to be changed into some other form, as it is that something should be begotten from nothing.

The endeavor after self-preservation is the essence itself of a thing. If, therefore, any virtue could be conceived prior to this of self-preservation, the essence itself of the thing would be conceived as prior to itself, which (as is self-evident) is absurd.

The endeavor after self-preservation is the primary and only foundation of virtue. For prior to this principle no other can be conceived, and without it no virtue can be conceived.

No one endeavors to preserve his own being for the sake of another object. For if a man endeavored to preserve his being for the sake of any other object, this object would then become the primary foundation of virtue (as is self-evident), which is an absurdity.

No one can desire to be happy, to act well and live well, who does not at the same time desire to be, to act, and to live, that is to say, actually to exist.

II

To act absolutely in conformity with virtue is nothing but acting according to the laws of our own proper nature. But only in so far as we understand do we act. Therefore, to act in conformity with virtue is nothing but acting, living, and preserving our being as reason directs, and doing so from the ground of seeking our own profit.[30]

In so far as a man is determined to action because he has inadequate ideas he suffers, that is to say, he does something which through his essence alone cannot be perceived, that is to say, which does not follow from his virtue. But in so far as he is determined to any action because he understands, he acts, that is to say he does something which is perceived through his essence alone, or which adequately follows from his virtue.

The Highest Virtue of Reason

All efforts which we make through reason are nothing but efforts to understand, and the mind, in so far as it uses reason, adjudges nothing as profitable to itself excepting that which conduces to understanding.

The mind, in so far as it reasons, desires nothing but to understand, nor does it adjudge anything to be profitable to itself excepting what conduces to understanding. But the mind possesses no certitude, unless in so far as it possesses adequate ideas, or in so far as it reasons. We do not know, therefore, that anything is certainly good, excepting that which actually conduces to understanding, and, on the other hand, we do not know that anything is evil excepting that which can hinder us from understanding.

The highest thing which the mind can understand is God, that is to say, Being absolutely infinite, and without whom nothing can be nor can be conceived, and therefore that which is chiefly profitable to the mind, or which is the highest good of the mind, is the knowledge of God. Again, the mind acts only in so far as it understands and only in so far can it be absolutely said to act in conformity with virtue. To understand, therefore, is the absolute virtue of the mind. But the highest thing which the mind can understand is God (as we have already demonstrated), and therefore the highest virtue of the mind is to understand or know God.

THE MORAL VALUE OF THE EMOTIONS I General Principles

That which so disposes the human body that it can be affected in many ways, or which renders it capable of affecting external bodies in many ways, is profitable to man, and is more profitable in proportion as by its means the body becomes better fitted to be affected in many ways, and to affect other bodies; on the other hand, that thing is injurious which renders the body less fitted to affect or be affected.

Whatever is effective to preserve the proportion of motion and rest which the parts of the human body bear to each other is good, and, on the contrary, that is evil which causes the parts of the human body to have a different proportion of motion and rest to each other.

In what degree these things may injure or profit the mind will be explained below. Here I observe merely that I understand the body to die when its parts are so disposed as to acquire a different proportion of motion and rest to each other. For I dare not deny that the human body, though the circulation of the blood and the other things by means of which it is thought to live be preserved, may, nevertheless, be changed into another nature altogether different from its own. No reason compels me to affirm that the body never dies unless it is changed into a corpse. Experience, indeed, seems to teach the contrary. It happens sometimes that a man undergoes such changes that he cannot very well be said to be the same man, as was the case with a certain Spanish poet of whom I have heard, who was seized with an illness, and although he recovered, remained, nevertheless, so oblivious of his past life that he did not believe the tales and tragedies he had composed were his own, and he might, indeed, have been taken for a grown-up child if he had also forgotten his native tongue. But if this seems incredible, what shall we say of children? The man of mature years believes the nature of children to be so different from his own, that it would be impossible to persuade him he had ever been a child, if he did not conjecture regarding himself from what he sees of others. But in order to avoid giving to the superstitious matter for new questions, I prefer to go no farther in the discussion of these matters.

II Value of Joy and Sorrow

Joy is an emotion by which the body's power of action is increased or assisted. Sorrow, on the other hand, is an emotion by which the body's power of action is lessened or restrained, and therefore joy is not directly evil, but good; sorrow, on the other hand, is directly evil.

III The Good Emotions

Cheerfulness is joy, which, in so far as it is related to the body, consists in this, that all the parts of the body are equally affected, that is to say, the body's power of action is increased or assisted, so that all the parts acquire the same proportion of motion and rest to each other. Cheerfulness, therefore, is always good, and can never be excessive. But melancholy is sorrow, which, in so far as it is related to the body consists in this, that the body's power of action is absolutely lessened or restrained, and melancholy, therefore, is always evil.

Pleasurable excitement is joy, which,
