“ As we have seen, for human reality, to be is to choose oneself ; nothing comes to it either from the outside or from within which it can receive or accept . Without any help whatsoever, it is entirely abandoned to the intolerable necessity of making itself be—down to the slightest detail. Thus freedom is not a being; it is the being of man— i.e ., his nothingness of being. ”
 Jean-Paul Sartre, Being and Nothingness (1943). copy citation
