“The scientist has to take 95 per cent of his subject on trust. He has to because he can't possibly do all the experiments, therefore he has to take on trust the experiments all his colleagues and predecessors have done. Whereas a mathematician doesn't have to take anything on trust. Any theorem that's proved, he doesn't believe it, really, until he goes through the proof himself, and therefore he knows his whole subject from scratch. He's absolutely 100 per cent certain of it. And that gives him an extraordinary conviction of certainty, and an arrogance that scientists don't have.”

“There is nothing in the nature of a miracle that should render it incredible:;: its credibility depends upon the nature of the evidence by which it is supported. An event of extreme probability will not necessarily command our belief unless upon a sufficiency of proof; and so an event which we may regard as highly improbable may command our belief if it is sustained by sufficient evidence. So that the credibility or incredibility of an event does not rest upon the nature of the event itself, but depends upon the nature and sufficiency of the proof which sustains it.”

“If my interlocutor desires to convince me that Jupiter has inhabitants, and that his description of them is accurate, it is for him to bring forward evidence in support of his contention. The burden of proof evidently lies on him; it is not for me to prove that no such beings exist before my non-belief is justified, but for him to prove that they do exist before my belief can be fairly claimed. Similarly, it is for the affirmer of God's existence to bring evidence in support of his affirmation; the burden of proof lies on him.”

“The source of Pyrrhonism comes from failing to distinguish between a demonstration, a proof and a probability. A demonstration supposes that the contradictory idea is impossible; a proof of fact is where all the reasons lead to belief, without there being any pretext for doubt; a probability is where the reasons for belief are stronger than those for doubting.”
