Happiness is not something you have in your hands; it's something you carry in your heart. Happiness is one thing that multiplies by division. Happiness is that peculiar sensation you acquire when you are too busy to be miserable. Happiness is that state of consciousness which proceeds from the achievement of one's values.

Civilization is the process of setting man free from men.

In the name of the values that keep you alive, do not let your vision of man be distorted by the ugly, the cowardly, the mindless in those who have never achieved his title. Do not lose your knowledge that man’s proper estate is an upright posture, an intransigent mind and a step that travels unlimited roads.

I don’t approve of religion.

To deal with men by force is as impractical as to deal with nature by persuasion.

All "public interest' legislation (and any distribution of money taken by force from some men for the unearned benefit of others) comes down ultimately to the grant of an undefined undefinable, non-objective, arbitrary power to some government officials. The worst aspect of it is not that such a power can be used dishonestly, but that it cannot be used honestly. The wisest man in the world, with the purest integrity, cannot find a criterion for the just, equitable, rational application of an unjust, inequitable, irrational principle.

The entire history of science is a progression of exploded fallacies.
