But though every created thing is, in this sense, a mystery, the word mystery cannot be applied to moral truth, any more than obscurity can be applied to light. ... Mystery is the antagonist of truth. It is a fog of human invention, that obscures truth, and represents it in distortion. Truth never envelops itself in mystery, and the mystery in which it is at any time enveloped is the work of its antagonist, and never of itself.

The Creation speaks a universal language, independent of human speech or human language, multiplied and various as they be. It is an ever-existing original, which every man can read. It cannot be forged; it cannot be counterfeited; it cannot be lost; it cannot be altered; it cannot be suppressed. It does not depend upon the will of man whether it shall be published or not; it publishes itself from one end of the earth to the other. It preaches to all nations and to all worlds; and this Word of God reveals to man all that is necessary for man to know of God.

All the tales of miracles, with which the Old and New Testament are filled, are fit only for impostors to preach and fools to believe.

I draw my idea of the form of government from a principle in nature, which no art can overturn, viz. that the more simple any thing is, the less liable it is to be disordered; and the easier repaired when disordered.

It is never to be expected in a revolution that every man is to change his opinion at the same moment. There never yet was any truth or any principle so irresistibly obvious that all men believed it at once. Time and reason must cooperate with each other to the final establishment of any principle; and therefore those who may happen to be first convinced have not a right to persecute others, on whom conviction operates more slowly. The moral principle of revolutions is to instruct, not to destroy.

The Allwise Creator hath been dishonored by being made the author of fable and the human mind degraded by believing it.

As property, honestly obtained, is best secured by an equality of rights, so ill-gotten property depends for protection on a monopoly of rights. He who has robbed another of his property, will next endeavor to disarm him of his rights, to secure that property; for when the robber becomes the legislator he believes himself secure.
