One-fifth of the people are against everything all the time.

The great enemy of truth is very often not the lie--deliberate, contrived and dishonest--but the myth--persistent, persuasive and unrealistic. Too often we hold fast to the cliches of our forebears. We subject all facts to a prefabricated set of interpretations. We enjoy the comfort of opinion without the discomfort of thought.

[Commencement Address at Yale University, June 11 1962]

Too often we... enjoy the comfort of opinion without the discomfort of thought.

Facts are cheels that winna ding, An' downs be disputed.

The purpose of life is to contribute in some way to making things better.
