If Camus and Sartre resemble each other in this area, it is because it is impossible to “solve” the dilemma of the realization that “one cannot define existence as necessity,” or that “there is absolutely no more reason for existing.” Since both thinkers conclude that we must continue to live, both are pushed to logical contradiction: both have to furnish non-arbitrary or necessary reasons for continuing to live in an arbitrary or non-necessary world.
