Proof is sufficient evidence or argument for the truth of a proposition.


  • "I refuse to prove that I exist," says God, "for proof denies faith, and without faith, I am nothing."
    "Oh," says man, "but the Babel fish is a dead give-away, isn't it? It proves You exist, and so therefore You don't."
    "Oh, I hadn't thought of that," says God, who promptly vanishes in a puff of logic.
    "Ah, that was easy," says man, and for an encore goes on to prove that black is white, and gets killed on the next zebra crossing.
    Most leading theologians claim that this argument is a load of dingo's kidneys.
  • PROOF, n. Evidence having a shade more of plausibility than of unlikelihood. The testimony of two credible witnesses as opposed to that of only one.
A very great deal more truth can become known than can be proven. ~ Richard Feynman

  • For when one's proofs are aptly chosen,
    Four are as valid as four dozen.

    • Anonymous maxim, widely used since at least the early 19th century (e.g. The Classical Journal , Vol. 40 (1829), p. 312).
