William James

“Those thoughts are truth which guide us to beneficial interaction with sensible particulars as they occur, whether they copy these in advance or not.”

“Truth lives, in fact, for the most part on a credit system. Our thoughts and beliefs pass, so long as nothing challenges them, just as bank-notes pass so long as nobody refuses them.”

“Truth is what works.”

“We have to live today by what truth we can get today and be ready tomorrow to call it falsehood.”

“Individuality is founded in feeling and the recesses of feeling, the darker, blinder strata of character, are the only places in the world in which we catch real fact in the making, and directly perceive how events happen, and how work is actually done.”

“Whatever universe a professor believes in must at any rate be a universe that lends itself to lengthy discourse. A universe definable in two sentences is something for which the professorial intellect has no use. No faith in anything of that cheap kind!”
