Morality pertains only to the sphere of man's free will - only to those actions which are open to his choice.
Ayn RandOne can study what exists and how consciousness functions; but one cannot analyze (or “prove”) existence as such, or consciousness as such. These are irreducible primaries. (An attempt to “prove” them is self-contradict ory: it is an attempt to “prove” existence by means of nonexistence, and consciousness by means of unconsciousness .)
