Knowledge is power. The real test of knowledge is not whether it is true but whether it empowers us. Scientists usually assume that no theory is 100% correct. Truth, consequently, is a poor test for knowledge. The real test is utility. A theory that enables us to do new things constitutes knowledge.

Truth is a naked and open daylight, that does not show the masques, and mummeries, and triumphs of the world, half so stately and daintily as candle-lights. . . A mixture of a lie doth ever add pleasure

The inquiry of truth, which is the love-making, or the wooing of it, the knowledge of truth, which is the presence of it, and the belief of truth, which is the enjoying of it, is the sovereign good of human nature.

Truth is a naked and open daylight

Truth is so hard to tell, it sometimes needs fiction to make it plausible.

No pleasure is comparable to the standing upon the vantage-ground of truth.
