I hold it certain that to open the doors of truth and to fortify the habit of testing everything by reason are the most effectual manacles we can rivet on the hands of our successors to prevent their manacling the people with their own consent.

Millions of innocent men, women and children, since the introduction of Christianity, have been burnt, tortured, fined and imprisoned; yet we have not advanced one inch towards uniformity. What has been the effect of coercion? To make one half the world fools, and the other half hypocrites. To support roguery and error all over the earth.

Even in Europe a change has sensibly taken place in the mind of man. Science has liberated the ideas of those who read and reflect, and the American example has kindled feelings of right in the people. An insurrection has consequently begun of science talents and courage against rank and birth, which have fallen into contempt. It has failed in its first effort, because the mobs of the cities, the instrument used for its accomplishment, debased by ignorance, poverty and vice, could not be restrained to rational action.

Conquest is not in our principles. It is inconsistent with our government.
