I like William James.

"James considered pragmatism to be both a method for analyzing philosophic problems and a theory of truth. He also saw it as an extension of the empiricist attitude in that it turned away from abstract theory and fixed or absolute principles and toward concrete facts, actions, and relative principles. James considered philosophies to be expressions of personal temperament and developed a correlation between "tough-minded" and "tender-minded" temperaments and empiricist and rationalist positions in philosophy. Theories, he felt, are "instruments" that humans use to solve problems and should be judged in terms of their "cash value" or practical consequences for human conduct."

"The test of a theory, belief, doctrine, must be its effect upon us, its practical consequences -- the pragmatic test: whatever works is true. The possession of truth is not an in itself but a preliminary means to vital satisfaction. Knowledge is an instrument for the sake of life, existing as practical utility. True ideas are those we can assimilate, validate, corroborate, and verify. Truth is not, therefore, useful because it is true; it is true because it is useful."

"A government that robs Peter to pay Paul can always depend on the support of Paul."
-- George Bernard Shaw

"What you risk reveals what you value."
-- Jeanette Winterson

The sons of Hermes love to play,
And only do their best when they
Are told they oughtn't;
Apollo's children never shrink
From boring jobs but have to think
Their work important.

- W. H. Auden, Under Which Lyre
