Napoleon, when hearing about Laplace's latest book, said, 'M. Laplace, they tell me you have written this large book on the system of the universe, and have never even mentioned its creator.' Laplace responds, 'Je n'avais pas besoin de cette hypothèse-là. (I had no need of that hypothesis.)
[When asked by a student if he believes in any gods] Oh, no. Absolutely not... The biggest advantage to believing in God is you don't have to understand anything, no physics, no biology. I wanted to understand.
Es gibt keinen Gott und Dirac ist sein Prophet. (There is no God and Dirac is his Prophet.) {A remark made during the Fifth Solvay International Conference (October 1927), after a discussion of the religious views of various physicists, at which all the participants laughed, including Dirac, as quoted in Teil und das Ganze (1969), by Werner Heisenberg, p. 119; it is an ironic play on the Muslim statement of faith, the Shahada, often translated: 'There is no god but Allah, and Muhammad is his Prophet.'}
[Religious belief is] outmoded and ridiculous. [Belief in gods was a] worn out but once useful crutch in mankind's journey towards truth. We consider the time has come for that crutch to be abandoned. It is a vacuous answer... To say that 'God made the world' is simply a more or less sophisticated way of saying that we don't understand how the universe originated. A god, in so far as it is anything, is an admission of ignorance. Religion utterly failed to provide an explanation of the biosphere other than that 'God made it all'. Then Darwin thundered over the horizon and in a few decades of observation and thought . . . arrived at an answer. I regard teaching religion as purveying lies. I came here today to de-corrupt you all.
For God to prove himself on demand, physically, would be a grave disappointment, and the strongest Christians should be considerably grateful that he chooses not to do so. The skeptic endlessly demands proof, yet God refuses to insult the true intelligence of man, the '6th sense', the chief quality, the acumen which distinguishes man from the rest of creation, faith.
