When we wish to correct with advantage, and to show another that he errs, we must notice from what side he views the matter, for on that side it is usually true, and admit that truth to him, but reveal to him the side on which it is false. He is satisfied with that, for he sees that he was not mistaken, and that he only failed to see all sides. Now, no one is offended at not seeing everything; but one does not like to be mistaken, and that perhaps arises from the fact that man naturally cannot see everything, and that naturally he cannot err in the side he looks at, since the perceptions of our senses are always true.

The whole visible world is only an imperceptible atom in the ample bosom of nature. No idea approaches it.

It is an infinite sphere, the centre of which is everywhere, the circumference nowhere. [30] In short it is the greatest sensible mark of the almighty power of God, that imagination loses itself in that thought.
