I wish from my Heart, I coud avoid concluding, that since Morality, according to your Opinion as well as mine, is determin'd merely by Sentiment, it regards only human Nature & human Life. This has been often urg'd against you, & the Consequences are very momentous.

All the philosophy … in the world, and all the religion, which is nothing but a species of philosophy, will never be able to carry us beyond the usual course of experience, or give us measures of conduct and behaviour different from those which are furnished by reflections on common life. No new fact can ever be inferred from the religious hypothesis; no event foreseen or foretold; no reward or punishment expected or dreaded, beyond what is already known by practice and observation.

What Danger can ever come from ingenious Reasoning & Enquiry? The worst speculative Sceptic ever I knew, was a much better man than the best superstitious Devotee & Bigot.

Where the moral sense is entire, there must be a sense of religion; and if a man who has no sense of religion live decently in society, he is more indebted for his conduct to good temper than to sound morals.

The enemies of Religion are awake; let not her friends sleep.
