Will and the Motility of Others

What, for notably Sartre and Levinas, plainly distinguishes the Look or the Face from other phenomena are elements of animation. Thus, the positing of the existence of another entails the attribution of Motility to an entity, i. e. of self-activation, just as does the ascription of a 'soul' to any fauna. But, Motility is Will. Hence, in at least those cases, the ground of the positing of the existence of others is their presumed possession of Will.
