"Space and Time! Two minor omissions that no one is likely to notice." — Neal Stephenson

"Though you, and most other Fellows of the Royal Society, are true Christians, and believers in Free Will, the very doctrines and methods that the Royal Society has promulgated have caused many to question the existence of God. ... As so much of civilization is rooted in those beliefs, this strikes me as one way in which our System of the World might be set up wrongly and thus self-doomed."

"But I'd have you know that my Stupidity and my Skepticism are two sides of the same coin, and are of a very particular kind, which is carefully thought out. ... The imbalance between the grand mysteries of the Universe as opposed to our own feeble faculties, leads us to set very modest expectations as to what we shall and shan't be able to understand--and makes us passing suspicious of anyone who propounds dogma or seems to phant'sy he has got it all figured out.

"Pray explain how it is that there may be such a thing as free will, and a spirit that may do as it pleases, unbound by the Mathematick laws of our Mechanical Philosophy."

"The mechanical world decays. Counterpoised against this tendency to decline must be some creative principle: the active seed--the Subtile Spirit."
