I consider Paine our greatest political thinker. As we have not advanced, and perhaps never shall advance, beyond the Declaration and Constitution, so Paine has had no successors who extended his principles. Although the present generation knows little of Paine's writings, and although he has almost no influence upon contemporary thought, Americans of the future will justly appraise his work. I am certain of it.
Truth is governed by natural laws and cannot be denied. Paine spoke truth with a peculiarly clear and forceful ring. Therefore time must balance the scales.
