SECT.  IX.  A Particular Examination of Nature.

After these comparisons, about which I only desire the reader to consult himself, without any argumentation, I think it is high time to enter into a detail of Nature.  I do not pretend to penetrate through the whole; who is able to do it?  Neither do I pretend to enter into any physical discussion.  Such way of reasoning requires a certain deep knowledge, which abundance of men of wit and sense never acquired; and, therefore, I will offer nothing to them but the simple prospect of the face of Nature.  I will entertain them with nothing but what everybody knows, and which requires only a little calm and serious attention.
