It is from the Bible that man has learned cruelty, rapine, and murder; for the belief of a cruel God makes a cruel man.

I believe in one God, and no more; and I hope for happiness beyond this life. I believe in the equality of humans; and I believe that religious duties consist in doing justice, loving mercy, and endeavoring to make our fellow creatures happy.

When the tongue or the pen is let loose in a frenzy of passion, it is the man, and not the subject, that becomes exhausted.

Toleration is not the opposite of intoleration, but it is the counterfeit of it. Both are despotisms. The one assumes to itself the right of withholding liberty of conscience, and the other of granting it. The one is the pope, armed with fire and fagot, and the other is the pope selling or granting indulgences.

The only idea man can affix to the name of God, is that of a first cause, the cause of all things. And, incomprehensibly difficult as it is for a man to conceive what a first cause is, he arrives at the belief of it, from the tenfold greater difficulty of disbelieving it. It is difficult beyond description to conceive that space can have no end; but it is more difficult to conceive an end. It is difficult beyond the power of man to conceive an eternal duration of what we call time; but it is more impossible to conceive a time when there shall be no time.

...the individuals themselves, each in his own personal and sovereign right, entered into a compact with each other to produce a government: and this is the only mode in which governments have a right to arise, and the only principle on which they have a right to exist.

I call not upon a few, but upon all: not on this state or that state, but on every state; up and help us; lay your shoulders to the wheel; better have too much force than too little, when so great an object is at stake.
