Thus, we can set up point number one: the good of an individual or a group of individuals requires that it be taken as an absolute end of our action; but we are not authorized to decide upon this end a priori. The fact is that no behavior is ever authorized to begin with, and one of the concrete consequences of existentialist ethics is the rejection of all the previous justifications which might be drawn from the civilization, the age, and the culture; it is the rejection of every principle of authority.
Existentialism does require a lot of responsibility, almost like anarchy.
