The Age of Reason

To My Fellow-Citizens of the United States of America: I PUT the following work under your protection. It contains my opinions upon Religion. You will do me the justice to remember, that I have always strenuously supported the Right of every Man to his own opinion, however different that opinion might be to mine. He who denies to another this right, makes a slave of himself to his present opinion, because he precludes himself the right of changing it.

The most formidable weapon against errors of every kind is Reason. I have never used any other, and I trust I never shall.

Your affectionate friend and fellow-citizen,

Thomas Paine
Luxembourg, 8th Pluviose,
Second Year of the French Republic, one and indivisible.
January 27, O. S. 1794.
