Nothing is so convenient as a decisive argument ... which must at least silence the most arrogant bigotry and superstition, and free us from their impertinent solicitations. I flatter myself, that I have discovered an argument ... which, if just, will, with the wise and learned, be an everlasting check to all kinds of superstitious delusion, and consequently, will be useful as long as the world endures. For so long, I presume, will the accounts of miracles and prodigies be found in all history, sacred and profane.

We may well ask, What causes induce us to believe in the existence of body? but 'tis vain to ask. Whether there be body or not? That is a point which we must take for granted in all our reasonings.

I have no kindness for you, and know you have as little for me. I will not, therefore, take any pains upon your account . . . Here then I leave you to labor alone; you treat me in the same manner. The seasons change, and both of us lose our harvests for want of mutual confidence and security.

When I think of God, when I think of him as existent, and when I believe him to be existent, my idea of him neither increases nordiminishes. But as it is certain there is a great difference betwixt the simple conception of the existence of an object, and the belief of it, and as this difference lies not in the parts or composition of the idea which we conceive; it follows, that it must lie in the manner in which we conceive it.

When men are most sure and arrogant they are commonly most mistaken, giving views to passion without that proper deliberation which alone can secure them from the grossest absurdities.
