If and when this is not so, then the question of weal and woe which incites to, or deters from, every action contemplated, can only relate to the agent himself; whence its performance, or non-performance is entirely egoistic, and without moral value. But if what I do is to take place solely on account of some one else; then it follows that =his= weal and woe must directly constitute =my= motive; just is, ordinarily, =my own= weal and woe form it. This narrows the limits of our problem, which may now be stated as follows: How is it possible that another's weal and woe should influence my will directly, that is, exactly in the same way as otherwise my own move it? How can that which affects another for good or bad become my immediate motive, and actually sometimes assume such importance that it more or less supplants my own interests, which are, as a rule, the single source of the incentives that appeal to me? Obviously, only because that other person becomes the ultimate object of my will, precisely as usually I myself am that object; in other words, because I directly desire weal, and not woe, for him, just as habitually I do for myself. This, however, necessarily implies that I suffer with him, and feel his woe, exactly as in most cases I feel only mine, and therefore desire his weal as immediately as at other times I desire only my own. But, for this to be possible, I must in some way or other be =identified= with him; that is, the =difference= between myself and him, which is the precise _raison d'être_ of my Egoism, must be =removed=, at least to a certain extent. Now, since I do not live in his skin, there remains only the knowledge, that is, the mental picture, I have of him, as the possible means whereby I can so far identify myself with him, that my action declares the difference to be practically effaced. The process here analysed is not a dream, a fancy floating in the air; it is perfectly real, and by no means infrequent. It is, what we see every day,--the phaenomenon of =Compassion=; in other words, the direct participation, independent of all ulterior considerations, in the sufferings of another, leading to sympathetic assistance in the effort to prevent or remove them; whereon in the last resort all satisfaction and all well-being and happiness depend. It is this Compassion alone which is the real basis of all =voluntary= justice and all =genuine= loving-kindness. Only so far as an action springs therefrom, has it moral value; and all conduct that proceeds from any other motive whatever has none. When once compassion is stirred within me, by another's pain, then his weal and woe go straight to my heart, exactly in the same way, if not always to the same degree, as otherwise I feel only my own. Consequently the difference between myself and him is no longer an absolute one.
