Famous quotes containing the words knowledge and/or proofs:
“Integrity without knowledge is weak and useless, and knowledge without integrity is dangerous and dreadful.”
—Samuel Johnson (1709–1784)
“To invent without scruple a new principle to every new phenomenon, instead of adapting it to the old; to overload our hypothesis with a variety of this kind, are certain proofs that none of these principles is the just one, and that we only desire, by a number of falsehoods, to cover our ignorance of the truth.”
—David Hume (1711–1776)
