Abstract: As a complete man's call for ego from the bottom of his heart, Erich Fromm's humanistic conscience is an autonomic morality which truly discards restraint and suppression. Having Inherited Nietzsche, freud and Marx's traditions, he made an original analysis on such controversial problems as man's essence and the relationship between passion, instinct and reason. The theory sheds some new light upon such theoretical questions as moral autonomy and practical problems as lose morality.
