The very aim and end of our institutions is just this: that we may think what we like and say what we think.

There are one-story intellects, two-story intellects, and three-story intellects with skylights. All fact collectors with no aim beyond their facts are one-story men. Two-story men compare reason and generalize, using labors of the fact collectors

I think that, as life is action and passion, it is required of a man that he should share the passion and action of his time at peril of being judged not to have lived.

I think that we should be eternally vigilant against attempts to check the expression of opinions that we loathe and believe to be fraught with death, unless they so imminently threaten immediate interference with the lawful and pressing purposes of the law that an immediate check is required to save the country.

It's faith in something and enthusiasm for something that makes a life worth living.

Men do not quit playing because they grow old; they grow old because they quit playing.
