Who would set a limit to the mind of man? Who would dare assert that we know all there is to be known?

But of all other stupendous inventions, what sublimity of mind must have been his who conceived how to communicate his most secret thoughts to any other person, though very far distant, either in time or place? And with no greater difficulty than the various arrangement of two dozen little signs upon paper? Let this be the seal of all the admirable inventions of man.

They know that it is human nature to take up causes whereby a man may oppress his neighbor, no matter how unjustly... Hence they have had no trouble in finding men who would preach the damnability and heresy of the new doctrine from the very pulpit..

The nature of the human mind is such that unless it is stimulated by images of things acting upon it from without, all remembrance of them passes easily away.

I have never met a man so ignorant that I couldn't learn something from him.

Nature is relentless and unchangeable, and it is indifferent as to whether its hidden reasons and actions are understandable to man or not.
