When men are brought face to face with their opponents, forced to listen and learn and mend their ideas, they cease to be children and savages and begin to live like civilized men. Then only is freedom a reality, when men may voice their opinions because they must examine their opinions.

We must protect the right of our opponents to speak because we must hear what they have to say.

In a free society the state does not administer the affairs of men. It administers justice among men who conduct their own affairs.

The essential discovery of maturity has little if anything to do with information about the names, the locations, and the sequence of facts; it is the acquiring of a different sense of life, a different kind of intuition about the nature of things.

It requires wisdom to understand wisdom: the music is nothing if the audience is deaf.

We are told about the world before we see it. We imagine most things before we experience them. And those preconceptions, unless education has made us acutely aware, govern deeply the whole process of perception.

Creative ideas come to the intuitive person who can face up to the insecurity of looking beyond the obvious.
