“Being established in my life, buttressed by my thinking nature, fastened down in this transcendental field which was opened for me by my first perception, and in which all absence is merely the obverse of a presence, all silence a modality of the being of sound, I enjoy a sort of ubiquity and theoretical eternity, I feel destined to move in a flow of endless life, neither the beginning nor the end of which I can experience in thought, since it is my living self who think of them, and since thus my life always precedes and survives itself.”

“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.”

“But the spectacle perceived does not partake of pure being. Taken exactly as I see it, it is a moment of my individual history, and since sensation is a reconstitution, it pre-supposes in me sediments left behind by some previous constitution, so that I am, as a sentient subject, a repository stocked with natural powers at which I am the first to be filled with wonder.”

“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 though them, all the rest.”

“The perception of other people and the intersubjective world is problematic only for adults. The child lives in a world which he unhesitatingly believes accessible to all around him. He has no awares of himself or of others as private subjectives, nor does he suspect that all of us, himself included, are limited to one certain point of view of the world. That is why he subjects neither his thoughts, in which he believes as they present themselves, to any sort of criticism. He has no knowledge of points of view. For him men are empty heads turned towards one single, self-evident world where everything takes place, even dreams, which are, he thinks, in his room, and even thinking, since it is not distinct from words.”

“The world is... the natural setting of, and field for, all my thoughts and all my explicit perceptions. Truth does not inhabit only the inner man, or more accurately, there is no inner man, man is in the world, and only in the world does he know himself. ”

“Humanity is not an aggregate of individuals, a community of thinkers, each of whom is guaranteed from the outset to be able to reach agreement with the others because all participate in the same thinking essence. Nor, of course, is it a single Being in which the multiplicity of individuals are dissolved and into which these individuals are destined to be reabsorbed. As a matter of principle, humanity is precarious: each person can only believe what he recognizes to be true internally and, at the same time, nobody thinks or makes up his mind without already being caught up in certain relationships with others, which leads him to opt for a particular set of opinions. Everyone is alone and yet nobody can do without other people, not just because they are useful (which is not in dispute here) but also when it comes to happiness.”
