John Adams on religion

I must study politics and war that my sons may have liberty to study mathematics and philosophy. My sons ought to study mathematics and philosophy, geography, natural history, naval architecture, navigation, commerce and agriculture in order to give their children a right to study painting, poetry, music, architecture, statuary, tapestry, and porcelain.

We’re in a war, dammit! We’re going to have to offend somebody!

It must be felt that there is no national security but in the nation’s humble acknowledged dependence upon God and His overruling providence.

The Bible is not my book, and Christianity is not my religion. I could never give assent to the long, complicated statements of Christian dogma.

Abraham Lincoln1809–1865

• Christianity

A man’s ethical behavior should be based effectually on sympathy, education, and social ties; no religious basis is necessary. Man would indeed be in a poor way if he had to be restrained by fear of punishment and hope of reward after death.

Albert Einstein1879–1955Religion and Science (1930)

• Morality

The most ridiculous concept ever perpetrated by Homo Sapiens is that the Lord God of Creation, Shaper and Ruler of the Universes, wants the sacharrine adoration of his creations, that he can be persuaded by their prayers, and becomes petulant if he does not recieve this flattery. Yet this ridiculous notion, without one real shred of evidence to bolster it, has gone on to found one of the oldest, largest and least productive industries in history.

Robert A. Heinlein1907–1988
