A man's life belongs to him - and the good is that he lives it. A man is a rational being. Only through reason can he determine what he values and by what actions he can achieve those values in his life. Man can use his consciousness to identify the laws of nature and the truth of the world around him. He can choose to live as a man.
Man is a being of volitional consciousness.
But he can only survive in this subhuman form in the event and to the extent that there are other men who create wealth and are willing to grant him something for nothing. Man exists on earth. The nature of earth and man exhibit certain natural laws, which determine what values are proper to the life of a man. If your goal is life on earth as a man then you must use your faculty of reason to achieve it. Man's life on earth is conditional.
