Man has a single basic choice: to think or not, and that is the gauge of his virtue. Moral perfection is an unbreached rationality-not the degree of your intelligence, but the full and relentless use of your mind, not the extent of your knowledge, but the acceptance of reason as an absolute.

A culture is made — or destroyed — by its articulate voices.

The uncontested absurdities of today are the accepted slogans of tomorrow.

And here, over the portals of my fort, I shall cut in the stone the word which is to be my beacon and my banner. The word which will not die should we all perish in battle. The word which can never die on this earth, for it is the heart of it and the meaning and the glory. The sacred word: EGO

Some day, the world will discover that, without thought, there can be no love.

Live and act within the limit of your knowledge and keep expanding it to the limit of your life. Redeem your mind from the hockshops of authority. Accept the fact that you are not omniscient, but playing a zombie will not give you omniscience-that your mind is fallible, but becoming mindless will not make you infallible-that an error made on your own is safer than ten truths accepted on faith, because the first leaves you the means to correct it, but the second destroys your capacity to distinguish truth from error.

So long as men desire to live together, no man may initiate the use of physical force against others. . . . When a man attempts to deal with me by force, I answer him by force. It is only as retaliation that force may be used and only against the man who starts its use. No, I do not share his evil or sink to his concept of morality: I merely grant him his choice, destruction, the only destruction he had the right to choose: his own.
