The Other is a concrete particular condition, not a formal category, of self-awareness

Evidence

Consciousness is consciousness of something. This means that transcendence is the constitutive structure of consciousness; that is, that consciousness is born supported by a being which is not itself. This is what we call the ontological proof. … Not only does pure subjectivity, if initially given, fail to transcend itself to posit the objective; a “pure” subjectivity disappears. What can properly be called subjectivity is consciousness (of) consciousness. But this consciousness (of being) consciousness must be qualified in some way, and it can be qualified only as revealing intuition or it is nothing. Now a revealing intuition implies something revealed. Absolute subjectivity can be established only in the face of something revealed; immanence can be defined only within the apprehension of a transcendent. … It is not a question of showing that the phenomena of inner sense imply the existence of objective spatial phenomena, but that consciousness implies in its being a non-conscious and transphenomenal being. … To say that consciousness is consciousness of something is to say that it must produce itself as a revealed-revelation of a being which is not it and which gives itself as already existing when consciousness reveals it. — Jean-Paul Sartre, Being and Nothingness, 151 (#expands, via linked claim)
