“One can ask why the I has to appear in the cogito {Descartes’ argument “I think therefore I am.}, since the cogito, if used rightly, is the awareness of pure consciousness, not directed at any fact or action. In fact the I is not necessary here, since it is never united directly to consciousness. One can even imagine a pure and self-aware consciousness which thinks of itself as impersonal spontaneity.”

“The consciousness that says 'I am' is not the consciousness that thinks.”

“I am beginning to believe that nothing can ever be proved. These are honest hypotheses which take the facts into account: but I sense so definitely that they come from me, and that they are simply a way of unifying my own knowledge. Not a glimmer comes from Rollebon's side. Slow, lazy, sulky, the facts adapt themselves to the rigour of the order I wish to give them; but it remains outside of them. I have the feeling of doing a work of pure imagination.”

“I am. I am, I exist, I think, therefore I am; I am because I think, why do I think? I don't want to think any more, I am because I think that I don't want to be, I think that I . . . because . . . ugh!”

“I am never any one of my attitudes, any one of my actions”

“Consciousness is a being the nature of which is to be conscious of the nothingness of its being.”

“My thought is me: that's why I can't stop. I exist because I think… and I can't stop myself from thinking. At this very moment - it's frightful - if I exist, it is because I am horrified at existing. I am the one who pulls myself from the nothingness to which I aspire.”
