(1) For the purpose of easier comprehension I have simplified the above presentation of compassion as the sole source of truly moral actions, by intentionally leaving out of consideration the incentive of Malice, which while it is equally useless to the self as compassion, makes the pain of others its ultimate purpose. We are now, however, in a position, by including it, to state the above proof more completely, and rigorously, as follows:—
There are only three fundamental springs of human conduct, and all possible motives arise from one or other of these. They are:
(a) Egoism; which desires the weal of the self, and is limitless.
(b) Malice; which desires the woe of others, and may develop to the utmost cruelty.
(c) Compassion; which desires the weal of others, and may rise to nobleness and magnanimity.
Every human act is referable to one of these springs; although two of them may work together. Now, as we have assumed that actions of moral worth are in point of fact realities; it follows that they also must proceed from one of these primal sources. But, by the eighth axiom, they cannot arise from the first, and still less from the second; since all conduct springing from the latter is morally worthless, while the offshoots of the former are in part neither good nor bad in themselves. Hence they must have their origin in the third incentive; and this will be established a posteriori in the sequel.
(2) Direct sympathy with another is limited to his sufferings, and is not immediately awakened by his well-being: the latter per se leaves us indifferent. J. J. Rousseau in his Émile (Bk. IV.) expresses the same view: "Première maxime: il n'est pas dans le cœur humain, de se mettre à la place des gens, qui sont plus heureux que nous, mais seulement de ceux, qui sont plus à plaindre,"[1] etc.
The reason of this is that pain or suffering, which includes all want, privation, need, indeed every wish, is positive, and works directly on the consciousness. Whereas the nature of satisfaction, of enjoyment, of happiness, and the like, consists solely in the fact that a hardship is done away with, a pain lulled: whence their effect is negative. We thus see why need or desire is the condition of every pleasure. Plato understood this well enough, and only excepted sweet odours, and intellectual enjoyment. (De Rep., IX., p. 264 sq., edit. Bipont.)[2] And Voltaire says: "Il n'est pas de vrais plaisirs, qu'avec de vrais besoins."[3] Pain, then, is positive, and makes itself known by itself: satisfaction or pleasure is negative—simply the removal of the former. This principle explains the fact that only the suffering, the want, the danger, the helplessness of another awakens our sympathy directly and as such. The lucky or contented man, as such, leaves us indifferent—in reality because his state is negative; he is without pain, indigence, or distress. We may of course take pleasure in the success, the well-being, the enjoyment of others: but if we do, it is a secondary pleasure, and caused by our having previously sorrowed over their sufferings and privations. Or else we share the joy and happiness of a man, not as such, but because, and in so far as, he is our child, father, friend, relation, servant, subject, etc. In a word, the good fortune, or pleasure of another, purely as such, does not arouse in us the same direct sympathy as is certainly elicited by his misfortune, privation, or misery, purely as such. If even on our own behalf it is only suffering (under which must be reckoned all wants, needs, wishes, and even ennui) that stirs our activity; and if contentment and prosperity fill us with indolence and lazy repose; why should it not be the same when others are concerned? For (as we have seen) our sympathy rests on an identification of ourselves with them. Indeed, the sight of success and enjoyment, purely as such, is very apt to raise the envy, to which every man is prone, and which has its place among the antimoral forces enumerated above.
In connection with the exposition of Compassion here given, as the coming into play of motives directly occasioned by another's calamity, I take the opportunity of condemning the mistake of Cassina,[4] which has been so often repeated. His view is that compassion arises from a sudden hallucination, which makes us put ourselves in the place of the sufferer, and then imagine that we are undergoing his pain in own own person. This is not in the least the case. The conviction never leaves us for a moment that he is the sufferer, not we; and it is precisely in his person, not in ours, that we feel the distress which afflicts us. We suffer with him, and therefore in him; we feel his trouble as his, and are not under the delusion that it is ours; indeed, the happier we are, the greater the contrast between our own state and his, the more we are open to the promptings of Compassion. The explanation of the possibility of this extraordinary phaenomenon is, however, not so easy; nor is it to be reached by the path of pure psychology, as Cassina supposed. The key can be furnished by Metaphysics alone; and this I shall attempt to give in the last Part of the present treatise.
