Opinions are not to be learned by rote, like the letters of an alphabet, or the words of a dictionary. They are conclusions to be formed, and formed by each individual in the sacred and free citadel of the mind, and there enshrined beyond the arm of law to reach, or force to shake; ay! and beyond the right of impertinent curiosity to violate, or presumptuous arrogance to threaten.

Do not confound noise with fame. The man who is remembered, is not always honored.

I shall say, that I feel myself virtuous, because my soul is at rest.

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.

The sciences have ever been the surest guides to virtue.

it is not that religion is merely useless, it is mischievous. It is mischievous by its idle terrors; it is mischievous by its false morality; it is mischievous by its hypocrisy; by its fanaticism; by its dogmatism; by its threats; by its hopes; by its promises.

Credulity is always ridiculous.
