To believe in the existence of sentient beings is to take into account their feelings, to believe that they have feelings, which may persist when I am not aware of them. A real belief, again, implies that, at the moment of belief, I have representative sensations or emotions corresponding to those which imply the actual presence of the object. To take sentience into account is to sympathize, to feel with. The only condition necessary for the sympathy to exist, and to be capable, therefore, of becoming a motive, is that I should really believe in the object, and hence have representative feelings. Systematically to ignore these relations is to act as I should act if I were an egoist in the extremest sense and held that there were no consciousness in the world except my own. But really to carry out this principle is to be an idiot; for an essential part of the world as interesting to me is constituted by the feelings of other conscious agents, and I can ignore their existence only at the cost of losing all the intelligence which distinguishes me from the lower animals. It is true that this vicarious sympathy, this pain at another's pain, may result in our simply getting rid of our own pain by going away from the sufferer, removing him, or dismissing him from our mind; as a fact, these methods are often pursued. But in many cases, such a course is impossible without the renunciation, at the same time, of many pleasures. If a man is to live with his friends, he must share their joys and sorrows; the choice is not between a particular pain and its absence, but involves the whole question of the renunciation of companionship. Emotions are inevitable, whether sympathetic or not, in proportion, not simply to the pain and pleasure at the moment, but to the intensity and degree in which they form part of the world of the individual,--the world constituted, not by mere sensations, but by the whole system of thoughts and emotions sustained by the framework of perception. The existence of pure malignity must, it is true, be admitted; it may be partly explained as love of the "sensational," the novel; the full explanation must be left to the psychologist. Sympathy is the natural and fundamental fact. If intellectual progress carried with it inferior sociability, it would tend to be eliminated; the world would be to the stupid; it must carry with it something which counterbalances the anti-social tendency. Reason is that which enables a human being to take account of future, as well as present pleasures. The working of the instincts or feelings, which dictates conduct, approximately coincides with the prevision as to the maximum of happiness obtainable by the agent; normally, it is prudent to be virtuous; and the sympathetic motives, so to speak, always develop within the framework provided by the other motives. To become reasonable is to act on general principles, and to act consistently; and this
