Every man builds his world in his own image; he has the power to choose, but no power to escape the necessity of choice. If he abdicates his power, he abdicates the status of man, and the grinding chaos of the irrational is what he achieves as his sphere of existenceโby his own choice.
Ayn RandThere must be only three supreme values which govern a person's life: Reason, Purpose, and Self-esteem. Reason, as his only tool of knowledge--Purpose, as his choice of the happiness which that tool must proceed to achieve--Self-esteem, as his inviolate certainty that his mind is competent to think and his person is worthy of happiness, which means: is worthy of living. These three values imply and require all of man's virtues, and all his virtues pertain to the relation of existence and consciousness: rationality, independence, integrity, honesty, justice, productiveness, pride.
Ayn RandValue is that which one acts to gain and/or keep. Virtue is the act by which one aims and/or keeps it.
