The relationship between Marx and ethics is often alluded to and rarely explored. In the academic fraternity he is basically considered as a social thinker and has been rarely acknowledged as a moral philosopher. He wrote about very little on ethics. Yet we can establish his ideas as the most influential foundation on ethics in the modern world. Marxist ethics wants to realize the humanistic ideals and to free itself of all kinds of exploitation through communist in nature. It generalizes the principles of communist morality formulated by the working people in the process of building a new society. Marxist ethics develops new and better relations among people that man is to man a friend, a brother. It is against all kinds of alienation of man from man.
