“Our friend Dirac has a creed; and the main tenet of that creed is: There is no God, and Dirac is his prophet.”

“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.'}”

“Different creeds are but different paths to reach the same God.”

“There is no God but one God and Art is his revealer; that’s my creed and I'll follow it to the end, to a hotter place than Pittsburgh if need be.”

“To hate man and worship God seems to be the sum of all the creeds.”

“Dirac found that the ratio of the electric force to the gravitational force of an electron-proton pair is roughly equal to the ratio of the age of the universe to the time it takes light to traverse an atom.”
