The readers of my _Ethics_ know that with me the ultimate foundation of morality is the truth which in the _Vedas_ and the _Vedanta_ receives its expression in the established, mystical formula, _Tat twam asi (This is thyself_), which is spoken with reference to every living thing, be it man or beast, and is called the _Mahavakya_, the great word. Actions which proceed in accordance with this principle, such as those of the philanthropist, may indeed be regarded as the beginning of mysticism. Every benefit rendered with a pure intention proclaims that the man who exercises it acts in direct conflict with the world of appearance; for he recognises himself as identical with another individual, who exists in complete separation from him. Accordingly, all disinterested kindness is inexplicable; it is a mystery; and hence in order to explain it a man has to resort to all sorts of fictions. When Kant had demolished all other arguments for theism, he admitted one only, that it gave the best interpretation and solution of such mysterious actions, and of all others like them. He therefore allowed it to stand as a presumption unsusceptible indeed of theoretical proof, but valid from a practical point of view. I may, however, express my doubts whether he was quite serious about it. For to make morality rest on theism is really to reduce morality to egoism; although the English, it is true, as also the lowest classes of society with us, do not perceive the possibility of any other foundation for it.
