To hold, as man’s sin, a fact not open to his choice is a mockery of morality. To hold man’s nature as his sin is a mockery of nature. 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. To destroy morality, nature, justice and reason by means of a single concept is a feat of evil hardly to be matched. Yet that is the root of your code.It's from John Galt's Speech in Atlas Shrugged (also reprinted in The New Intellectual).
The passage on Original Sin in Galt's Speech covers several paragraphs - this quote is just part of one of them.
