History knows no scruples and no hesitation. Inert and unerring, she flows towards her goal. At every bend in her course she leaves the mud which she carries and the corpses of the drowned.

Space-ships and time machines are no escape from the human condition. Let Othello subject Desdemona to a lie-detector test; his jealousy will still blind him to the evidence. Let Oedipus triumph over gravity; he won't triumph over his fate.

Two half truths do not make a truth.

History knows no scruples and no hesitation. Inert and unnering flows towards her goal. History knows herway. She makes no mistakes.

The inner censor of the mind of the true believer completes the work of the public censor; his self-discipline is as tyrannical as the obedience imposed by the regime; he terrorizes his own conscience into submission;he carries his private Iron Curtain inside his skull, to protect his illusions against the intrusion of reality.

The principle mark of genius is not perfection but originality, the opening of new frontiers.

As modern physics started with the Newtonian revolution, so modern philosophy starts with what one might call the Cartesian Catastrophe. The catastrophe consisted in the splitting up of the world into the realms of matter and mind, and the identification of 'mind' with conscious thinking. The result of this identification was the shallow rationalism of l' esprit Cartesien, and an impoverishment of psychology which it took three centuries to remedy even in part.
