'...we can be nothing without playing at being. "If I am a café waiter... this can be only in the mode of not being one." And that is true. If I could be a café waiter, I should suddely constitute myself as a contingent block of identity. And that I am not. This contingent being in-itself always escapes me. But in order that I may freely give a meaning to the obligations which my state involves, then in one sense at the heart of the for-itself, as a perpetually evanescent totality, being-in-itself must be given as the evanescent contingency of my situation.' - From Being and Nothingness (1943)
