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
