Of all the tyrannies that affect mankind, tyranny in religion is the worst

Tyranny, like hell, is not easily conquered; yet we have this consolation with us, that the harder the conflict, the more glorious the triumph. What we obtain too cheap, we esteem too lightly: it is dearness only that gives every thing its value.

The trade of governing has always been monopolized by the most ignorant and the most rascally individuals of mankind.

The world is my country, all mankind are my brethren, and to do good is my religion.

Whenever we read the obscene stories, the voluptuous debaucheries, the cruel and torturous executions, the unrelenting vindictiveness, with which more than half the Bible is filled, it would be more consistent that we called it the word of a demon, than the word of God. It is a history of wickedness, that has served to corrupt and brutalize mankind; and, for my part, I sincerely detest it, as I detest everything that is cruel.

Reason and Ignorance, the opposites of each other, influence the great bulk of mankind. If either of these can be rendered sufficiently extensive in a country, the machinery of Government goes easily on. Reason obeys itself; and Ignorance submits to whatever is dictated to it.
