For how, otherwise than metaphysically, are we to account for even the smallest offering of alms made with absolutely no other object than that of lessening the want which afflicts a fellow-creature? Such an act is only conceivable, only possible, in so far as the giver =knows= that it is his very self which stands before him, clad in the garments of suffering; in other words, so far as he recognises the essential part of his own being, under a form not his =own=.[10] It now becomes apparent, why in the foregoing part I have called Compassion the great mystery of Ethics. He, who goes to meet death for his fatherland, has freed himself from the illusion which limits a man's existence to his own person. Such a one has broken the fetters of the _principium individuationis_. In his widened, enlightened nature he embraces all his countrymen, and in them lives on and on. Nay, he reaches forward to, and merges himself in the generations yet unborn, for whom he works; and he regards death as a wink of the eyelids, so momentary that it does not interrupt the sight. We may here sum up the characteristics of the two human types above indicated. To the Egoist all other people are uniformly and intrinsically strangers. In point of fact, he considers nothing to be truly real, except his own person, and regards the rest of mankind practically as troops of phantoms, to whom he assigns merely a relative existence, so far as they may be instruments to serve, or barriers to obstruct, his purposes; the result being an immeasurable difference, a vast gulf between =his ego= on the one side, and the =non-ego= on the other. In a word, he lives exclusively centred in his own individuality, and on his death-day he sees all reality, indeed the whole world, coming to an end along with himself.[11] Whereas the Altruist discerns in all other persons, nay, in every living thing, his own entity, and feels therefore that his being is commingled, is identical with the being of whatever is alive. By death he loses only a small part of himself. Patting off the narrow limitations of the individual, he passes into the larger life of all mankind, in whom he always recognised, and, recognising, loved, his very self; and the illusion of Time and Space, which separated his consciousness from that of others, vanishes. These two opposite modes of viewing the world are probably the chief, though not indeed the sole cause of the difference we find between very good and exceptionally bad men, as to the manner in which they meet their last hour.
