Ayn Rand, Atlas Shrugged

Your moral code begins by damning man as evil, then demands that he practice a good which it defines as impossible for him to practice…It demands that he starts, not with a standard of value, but with a standard of evil, which is himself, by means of which he is then to define the good: the good is that which he is not. A sin without volition is a slap at morality and an isolent contradiction in terms: that which is outside the possibility of choice is outside the province of morality. If man is evil by birth, he has no will, no power to change it; if he has no will, he can be neither good nor evil; a robot is amoral. To hold a man’s sin, a fact not open to his choice is a mockery of morality…To punish him for a crime he committed before he was born is a mockery of justice. To hold him guilty in a matter where no innocence exists is a mockery of reason. (The) myth decleares that he ate the fruit of the tree of knowledge-he acquired a mind and became a rational being. It was the knowledge of good and evil-he became a moral being…The evils for which they damn him are reasn, morality, creativeness, joy-all the cardinal values of his existence….the essence of his nature as a man. Whatever he was- that robot in the Garden of Eden, who existed without mind, without values, without labor, without love- he was not a man.
