True reflection presents me to myself not as idle and inaccessible subjectivity, but as identical with my presence in the world and to others, as I am now realizing it: I am all that I see, I am an intersubjective field, not despite my body and historical situation, but, on the contrary, by being this body and this situation, and through them, all the rest.

All thought of something is at the same time self-consciousness [...] At the root of all our experiences and all our reflections, we find [...] a being which immediately recognises itself, [...] and which knows its own existence, not by observation and as a given fact, nor by inference from any idea of itself, but through direct contact with that existence. Self-consciousness is the very being of mind in action.
