There 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.

I know not if this earth on which I stand is the core of the universe or if it is but a speck of dust lost in eternity. I know not and I care not. For I know what happiness is possible to me on earth. And my happiness needs no higher aim to vindicate it. My happiness is not the means to any end. It is the end. It is its own goal. It is its own purpose.

What is man? He's just a collection of chemicals with delusions of grandeur.
