Choosing this or that is to affirm at the same time the value of what we choose because we can never choose evil. We always choose the good, and nothing can be good for any of us unless it is a good for all. 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.
- Jean-Paul Sartre (Existentialism is a Humanism)
