Will and the Existence of Others

The question of 'the existence of others' is typically classified as a cognitive problem, i. e. as a possible fact requiring methodical grounding. Even for Levinas, for whom it is the fundamental problem of Ethics, that existence is given as a phenomenological datum, i. e. the Face of an other. In contrast, for both Aristotle and Kant, the existence of another is a practical problem, i. e. posited in the treatment of another as the same kind of 'Self' that one is. The shortcoming of such an analogy is that it assimilates an other to oneself. In contrast, in Will, the principle of indefinite Diversification, one comports oneself toward an other qua irreducibly other, i. e. what it posits is the existence of a truly 'other'.
