ABSTRACT
When we say that man chooses himself, not only do we mean that each of us must choose himself, but also that in choosing himself, he is choosing for all men. In fact, in creating the man each of us wills ourselves to be, there is not a single one of our actions that does not at the same time create an image of man as we think he ought to be. […] If, moreover, existence precedes essence and we will to exist at the same time as we fashion our image, that image is valid for all and for our whole era. Our responsibility is thus much greater than we might have supposed, because it concerns all mankind.
