I found the human heart empty and insipid everywhere except in books. - Jean-Paul Sartre

وقتی که آدم هیچ کاری انجام نمی دهد گمان می کند که مسئول همه کارهاست
(گوشه نشینان آلتونا)

You see, I'm fond of teasing, it's
a second nature with me — and I'm used to teasing myself. Plaguing myself, if you prefer; I don't tease nicely.

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.
