I never walked through the streets of any city with as much satisfaction as those of Philadelphia. The neatness and cleanliness of all animate and inanimate things, houses, pavements, and citizens, is not to be surpassed.

No man can see his own prejudices.

Of the thousands who have paid homage to virtue, barely one has thought to inspect the pedestal on which it stands.

Moral truth, resting entirely upon the ascertained consequences of actions, supposes a process of observation and reasoning.

Persecution for opinion is the master vice of society.

We are on the earth, and they tell us of heaven; we are human beings, and they tell us of angels and devils; we are matter, and they tell us of spirit; we have five senses whereby to admit truths, and a reasoning faculty by which to build our belief upon them; and they tell us of dreams dreamed thousands of years ago, which our experience flatly contradicts.

Religion may be defined thus: a belief in, and homage rendered to, existences unseen and causes unknown.
