solitude of the ego

is the notion that rather than being a human being within the world, I am the ego that places the world in question.

Owing to this epoche human solitude has become something radically different: it has become transcendental solitude, the solitude of the Ego. As Ego I am for myself not a human being within the world that is in being... rather, I am the ego that places the world in question regarding its entire being, and hence too regarding its being in this way or that. (Husserl 1931: 5-6)
