“There is nothing divine about morality, it is a purely human affair.”

“The presumption of divine intervention in human affairs violates my sense of an orderly and comprehensible universe.”

“Human affairs are not governed ultimately by historical events, fate, or chance, but by God...Divine purpose moving steadily from beginning to end.”

“Human affairs are so obscure and various that nothing can be clearly known.”

“We proclaim human intelligence to be morally valuable per se because we are human. If we were birds, we would proclaim the ability to fly as morally valuable per se. If we were fish, we would proclaim the ability to live underwater as morally valuable per se. But apart from our obviously self-interested proclamations, there is nothing morally valuable per se about human intelligence.”

“Remember that there is nothing stable in human affairs; therefore avoid undue elation in prosperity, or undue depression in adversity.”
