There are no contradictions. If you find one, check your premises.

There is only one source of authentic self-confidence: reason.

There is no affirmation without the one who affirms. in this sense, everything to which you grant your love is yours

For they have nothing to fight me with, save the brute force of their numbers. I have my mind.

If a man speculates on what 'society' should do for the poor, he accepts thereby the collectivist premise that men's lives belong to society and that he, as a member of society, has the right to dispose of them...that psychological confession reveals the enormity of the extent to which altruism erodes men's capacity to grasp the concept of rights or the value of an individual life.

[Altruism] is a moral system which holds that man has no right to exist for his own sake, that service to others is the sole justification of his existence, and that self-sacrifice is his highest moral duty, value and virtue. This is the moral base of collectivism, of all dictatorships.

The symbol of all relationships among such men, the moral symbol of respect for human beings, is the trader. We, who live by values, not by loot, are traders, both in matter and in spirit. A trader is a man who earns what he gets and does not give or take the undeserved.
