Man—every man—is an end in himself, not a means to the ends of others; he must live for his own sake, neither sacrificing himself to others nor sacrificing others to himself; he must work for his rational self-interest, with the achievement of his own happiness as the highest moral purpose of his life.
Ayn RandMan has been called a rational being, but rationality is a matter of choice... Man has to be a man-by choice; he has to hold his life as a value-by choice; he has to learn to sustain it-by choice; he has to discover the values it requires and practice his virtues by choice. A code of values accepted by choice is a code of morality.
Ayn RandThe moral justification of capitalism does not lie in the altruist claim that it represents the best way to achieve 'the common good.' It is true that capitalism does -- if that catch-phrase has any meaning -- but this is merely a secondary consequence. The moral justification for capitalism lies in the fact that it is the only system consonant with man's rational nature, that it protects man's survival qua man, and that its ruling principle is: justice
