"Human-reality is free because it is not enough . It is free because it is perpetually wrenched away from itself and because it has been separated by a nothingness from what it is and what it will be. It is free, finally, because its present being is itself a nothingness in the form of the "reflection-reflecting." Man is free because he is not himself but presence to himself. The being which is what it is cannot be free. Freedom is precisely the nothingness which is made-to-be at the heart of man and which forces human-reality to make itself instead of to be . 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." —Sartre, Being and Nothingness
