"He grew up in this way. He became enamored of the philosophy of Nietzsche. Your Honor, I have read almost everything that Nietzsche ever wrote. He was a man of a wonderful intellect; the most original philosopher of the last century. Nietzsche believed that some time the superman would be born, that evolution was working toward the superman. He wrote one book, Beyond Good and Evil, which was a criticism of all moral codes as the world understands them; a treatise holding that the intelligent man is beyond good and evil, that the laws for good and the laws for evil do not apply to those who approach the superman. He wrote on the will to power. Nathan Leopold is not the only boy who has read Nietzsche. He may be the only one who was influenced in the way that he was influenced."
