These different systems may be reduced to a single one, which is called the ethics of sentiment.

It is not difficult to show the difference which separates these ethics from those of egoism. Egoism is the exclusive love of self, is the thoughtful and permanent search for our own pleasure and our own well-being.

What is there more opposed to interest than benevolence? In benevolence, far from wishing others well by reason of our interest, we will voluntarily risk something, we will make some sacrifice in order to serve an honest man who has coined our heart. If even in this sacrifice the soul feels a pleasure, this pleasure is only the involuntary accompaniment of sentiment, it is not the end proposed,—we feel it without having sought it. It is, indeed, permitted the soul to taste this pleasure, for it is nature herself that attaches it to benevolence.

Sympathy, like benevolence, is related to another than ourselves,—our interest is not its starting-point. The soul is so constituted that it is capable of suffering on account of the sufferings of an enemy. That a man does a noble action, although it opposes our interests, awakens in us a certain sympathy for that action and its author.

The attempt has been made to explain the compassion with which the suffering of one of our fellow-men inspires us by the fear that we have of feeling it in our turn. But the unhappiness for which we feel compassion, is often so far from us and threatens us so little, that it would be absurd to fear it. Doubtless, that sympathy may have existence it is necessary to experience suffering,—non ignara mali. For how do you suppose that I can be sensible to evils of which I form to myself no idea? But that is only the condition of sympathy. It is not at all necessary to conclude that it is only a remembrance of our own ills or the fear of ills to come.

No recurrence to ourselves can account for sympathy. In the first place, it is involuntary, like antipathy. Then it cannot be supposed that we sympathize with any one in order to win his benevolence; for he who is its object often knows not what we feel. What benevolence are we seeking, when we sympathize with men that we have never seen, that we never shall see, with men that are no more?

Egoism admits all pleasures; it repels none; it may, if it is enlightened, if it has become delicate and refined, recommend, as more durable and less alloyed, the pleasures of sentiment. The ethics of sentiment would then be confounded with those of egoism, if they should prescribe obedience to sentiment for the pleasure that we find in it. There would, then, be no disinterestedness in it,—the individual would be the centre and sole end of all his actions. But such is not the case. The charm of the pleasures of conscience comes from the very fact that we are forgetful of self in the action that has produced them. So if nature has joined to sympathy and benevolence a true enjoyment, it is on condition that these sentiments remain as they are, pure and disinterested; you must only think of the object of your sympathy and benevolence in order that benevolence and sympathy may receive their recompense in the pleasure which they give. Otherwise, this pleasure no longer has its reason for existence, and it is wanting as soon as it sought for itself. No metamorphose of interest can produce a pleasure attached to disinterestedness alone.

The ethics of egoism are only a perpetual falsehood,—they preserve the names consecrated by ethics, but they abolish ethics themselves; they deceive humanity by speaking to humanity its own language, concealing under this borrowed language a radical opposition to all the instincts, to all the ideas that form the treasure of mankind. On the contrary, if sentiment is not the good itself, it is its faithful companion and useful auxiliary. It is as it were the sign of the presence of the good, and renders the accomplishment of it more easy. We always have sophisms at our disposal, in order to persuade ourselves that our true interest is to satisfy present passion; but sophism has less influence over the mind when the mind is in some sort defended by the heart. Nothing is, therefore, more salutary than to excite and preserve in the soul those noble sentiments that lift us above the slavery of personal interest. The habit of participating in the sentiments of virtuous men disposes us to act like them. To cultivate in ourselves benevolence and sympathy is to fertilize the source of charity and love, is to nourish and develop the germ of generosity and devotion.

It is seen that we render sincere homage to the ethics of sentiment. These ethics are true,—only they are not sufficient for themselves; they need a principle which authorizes them.

I act well, and I feel on account of it an internal satisfaction: I do evil, and feel remorse on account of it. These two sentiments do not qualify the act that I have just done, since they follow it. Would it be possible for us to feel any internal satisfaction for having acted well if we did not judge that we had acted well?—any remorse for having done evil, if we did not judge that we had done evil? At the same time that we do such or such an act, a natural and instinctive judgment characterizes it, and it is in consequence of this judgment that our sensibility is moved. Sentiment is not this primitive and immediate judgment; far from forming the basis of the idea of the good, it supposes it. It is manifestly a vicious circle to derive the knowledge of the good from that which would not exist without this knowledge.[204]
