[T]he existentialist description of life as meaningless does not imply that there is no reason to live. It implies that there is no invariant, objectively defensible reason to live. Individuals are free to act on the basis of the values that feel valid for them in the specific context in which they find themselves. Thus, far from being a call for individuals to give up on life, existentialism is a call for individuals to live passionately out of their own personal values.
