I felt myself in a solitude so frightful that I contemplated suicide. What held me back was the idea that no one, absolutely no one, would be moved by my death, that I would be even more alone in death than in life.
Jean-Paul SartreHe walked on in silence, the solitary sound of his footsteps echoing in his head, as in a deserted street, at dawn. His solitude was so complete, beneath a lovely sky as mellow and serene as a good conscience, amid that busy throng, that he was amazed at his own existence; he must be somebody else's nightmare, and whoever it was would certainly awaken soon.
Jean-Paul SartreOne can ask why the I has to appear in the cogito {Descartesโ argument โI 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.
