There is no society in human history that ever suffered because its people became too reasonable.

No atrocity was ever committed because people were being too reasonable, too skeptical, or too independently minded.

No civilization, including Plato's, has ever been destroyed because its citizens learned too much.

No people could despise its own language, customs, and institutions and hope to avoid national death.

Sanity doesn’t suffer, ever.

Nobody...ought to be punished for religious opinions.

No one ever lost money underestimating the intelligence of the American public.

In religious matters a traveller loses nothing by civility.

Preservation of one's own culture does not require contempt or disrespect for other cultures.

There's no such thing as being too respectful of other people's traditions.

In no case is there a loss of personal existence to deplore. Nor will there ever be.

Truth suffers no loss if a vehement youth fails in finding it, in the same way that virtue and religion suffer no detriment if a criminal denies them.

An appeal to the reason of the people has never been known to fail in the long run.

I know no religion that destroys courtesy, civility, and kindness.
