Ayn Rand identified the three principle virtues of man as Reason, Purpose, and Self-Esteem.
The first of these virtues, Reason, refers to the fact that Reason is the ONLY source of knowledge available to man. Divine revelation, feelings, astrology, etc. do not reveal knowledge in the sense of revealing a truth about the world we live in. While some might intuit a truth, it can only be known as true if it passes the test of Reason.
The second of these virtues, Purpose, refers to man's choice of the kind of happiness a person chooses to pursue.
The third of these virtues, Self-Esteem, means having confidence that man's mind is competent to think and that he is worthy of happiness.
