Superman, according to Nietzsche has reached a state of being where he is no longer affected by "pity, suffering, tolerence of the weak, the power of the soul over the body, the belief in an afterlife, the corruption of modern values." Superman is constantly changing and in a state of rebirth and growth. He determines what is good and what is evil, not allowing religion or society to determine these things for him. The Superman finds his happiness in this way. He uses a reason that is independent of the modern values of society or religion. He determines his own values. This creation of his own values gives him joy, and in order for the Superman to cope with a changing world, the Superman must constantly change. This constant state of change is a constant source of joy, leaving little or no room for suffering. The Superman does not believe in an afterlife or the power of the soul over the body because he does not believe in religion and has no proof of an afterlife or a God. Therefore, he makes the most out of this life, not depending on a reward in Heaven or a punishment in Hell for what he has done on Earth. The Superman does not pity or tolerate the weak. He feels that human compassion is the greatest weakness of all, because it allows the weak to restrict the growth of the strong. In Thus Spake Zarathustra, Nietzsche, through Zarathustra, says "I teach you the overman. Man is something that shall be overcome [surpassed]. What have you done to overcome [surpass] him? All beings so far have created something beyond themselves; and do you want to be the ebb of this great flood and even go back to the beasts rather than overcome man? What is the ape to man? A laughingstock or a painful embarrassment. And man shall be just that for the overman: a laughingstock or a painful embarrassment..."
