The opinions of men are not the object of civil government, nor under its jurisdiction.

[The purpose of a written constitution is] to bind up the several branches of government by certain laws, which, when they transgress, their acts shall become nullities; to render unnecessary an appeal to the people, or in other words a rebellion, on every infraction of their rights, on the peril that their acquiescence shall be construed into an intention to surrender those rights.

I tremble for my country when I reflect that God is just: that his justice cannot sleep forever: that, considering numbers, nature, and natural means only, a revolution of the wheel of fortune, an exchange of situation, is among possible events: that it may become probable by supernatural interference!

When I hear another express an opinion which is not mine, I say to myself, he has a right to his opinion, as I to mine. Why should I question it?

Errors of opinion may be tolerated where reason is left free to combat it.
