There is but one honest limit to the rights of a sentient being; it is where they touch the rights of another sentient being.

Credulity is always a ridiculous, often a dangerous failing: it has made of many a clever man, a fool; and of many a good man, a knave.

The world is full of religion, and full of misery and crime.

It is in vain that we would circumscribe the power of one half of our race, and that half by far the most important and influential. If they exert it not for good, they will for evil; if they advance not knowledge, they will perpetuate ignorance. Let women stand where they may in the scale of improvement, their position decides that of the race.

He who lives in the single exercise of his mental faculties, however usefully or curiously directed, is equally an imperfect animal with the man who knows only the exercise of muscles.

Credulity is always ridiculous.

How prone we are to come to the consideration of every question with heads and hearts pre-occupied! How prone to shrink from any opinion, however reasonable, if it be opposed to any, however unreasonable, of our own! How disposed are we to judge, in anger, those who call upon us to think, and encourage us to enquire! To question our prejudices seems nothing less than sacrilege; to break the chains of our ignorance, nothing short of impiety!
