The right to agree with others is not a problem in any society; it is the right to disagree that is crucial. It is the institution of private property that protects and implements the right to disagree - and thus keeps the road open to man's most valuable attribute: the creative mind.

[T]he only real moral crime that one man can commit against another is the attempt to create, by his words or actions, an impression of the contradictory, the impossible, the irrational, and thus shake the concept of rationality in his victim.

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.

The right to life means that a man has the right to support his life by his own work (on any economic level, as high as his ability will carry him); it does not mean that others must provide him with the necessities of life.

The Middle Ages were an era of mysticism, ruled by blind faith and blind obedience to the dogma that faith is superior to reason. The Renaissance was specifically the rebirth of reason, the liberation of man's mind, the triumph of rationality over mysticism - a faltering, incomplete, but impassioned triumph that led to the birth of science, of individualism, of freedom.

The man who refuses to judge, who neither agrees nor disagrees, who declares that there are no absolutes and believes that he escapes responsibility, is the man responsible for all the blood that is now spilled in the world

The man who speaks to you of sacrifice, speaks of slaves and masters. And intends to be the master.

...if men are to be ruled, then the enemy is reason.

The purpose of man's life...is to become an abject zombie who serves a purpose he does not know, for reasons he is not to question.
