What objectivity and the study of philosophy requires is not an 'open mind,' but an active mind - a mind able and eagerly willing to examine ideas, but to examine them criticially.

Congress shall make no law abridging the freedom of production and trade.

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

Collectivism, as an intellectual power and a moral ideal, is dead. But freedom and individualism, and their political expression, capitalism, have not yet been discovered.

If capitalism had never existed, any honest humanitarian should have been struggling to invent it. But when you see men struggling to evade its existence, to misrepresent its nature, and to destroy its last remnants - you maybe sure that whatever their motives, love of man is not one of them.

You have been called selfish for the courage of acting on your own judgement and bearing sole responsibility for your own life. You have been called arrogant for your independent mind. You have been called cruel for your unyielding integrity. You have been calle anti social for the vision that made you venture upon undiscovered roads.

I'm not brave enough to be a coward; I see the consequences too clearly.
