Onus Of Proof Quotes

God is an hypothesis, and, as such, stands in need of proof: the onus probandi rests on the theist.

The Oracle pursued a logical course of confuting theism, and leaving 'a-theism' the negative result. It did not, in the absurd terms of common religious propaganda, 'deny the existence of God.' It affirmed that God was a term for an existence imagined by man in terms of his own personality and irreducible to any tenable definition. It did not even affirm that 'there are no Gods'; it insisted that the onus of proof as to any God lay with the theist, who could give none compatible with his definitions.

The onus of proof rests with him who negates, just as it rests with him who affirms. Propositions, negative or affirmative, if not self-evident, necessarily require proof. Negating without possessing knowledge is, in effect, making a statement based on no knowledge

[There is] a widespread approach to ideas which Objectivism repudiates altogether: agnosticism. I mean this term in a sense which applies to the question of God, but to many other issues also, such as extra-sensory perception or the claim that the stars influence man’s destiny. In regard to all such claims, the agnostic is the type who says, “I can’t prove these claims are true, but you can’t prove they are false, so the only proper conclusion is: I don’t know; no one knows; no one can know one way or the other.” The agnostic viewpoint poses as fair, impartial, and balanced. See how many fallacies you can find in it. Here are a few obvious ones: First, the agnostic allows the arbitrary into the realm of human cognition. He treats arbitrary claims as ideas proper to consider, discuss, evaluate—and then he regretfully says, “I don’t know,” instead of dismissing the arbitrary out of hand. Second, the onus-of-proof issue: the agnostic demands proof of a negative in a context where there is no evidence for the positive. “It’s up to you,” he says, “to prove that the fourth moon of Jupiter did not cause your sex life and that it was not a result of your previous incarnation as the Pharaoh of Egypt.” Third, the agnostic says, “Maybe these things will one day be proved.” In other words, he asserts possibilities or hypotheses with no jot of evidential basis. The agnostic miscalculates. He thinks he is avoiding any position that will antagonize anybody. In fact, he is taking a position which is much more irrational than that of a man who takes a definite but mistaken stand on a given issue, because the agnostic treats arbitrary claims as meriting cognitive consideration and epistemological respect. He treats the arbitrary as on a par with the rational and evidentially supported. So he is the ultimate epistemological egalitarian: he equates the groundless and the proved. As such, he is an epistemological destroyer. The agnostic thinks that he is not taking any stand at all and therefore that he is safe, secure, invulnerable to attack. The fact is that his view is one of the falsest—and most cowardly—stands there can be.

God is an hypothesis, and, as such, stands in need of proof: the onus probandi [burden of proof] rests on the theist. —Percy Bysshe Shelley

The onus of proof rests with him who negates, just as it rests with him who affirms. Propositions, negative or affirmative, if not self-evident, necessarily require proof. Negating without possessing knowledge is, in effect, making a statement based on no knowledge.
