Thank you very, very much Thosp.

So lets see if I have this straight.
Basically Sartre is saying, to be a truly free human being you must come to the realization that you are the collective of all human beings.

Isn't that kind of like someone who said,....... I shall not be free until the last living soul on earth is free.

Or like Schindler, from Schinler's List who suffered from the haunting fact that he could have saved just one more.
Just wondering
