It is quite beyond me how anyone can believe God speaks to us in books and stories. If the world does not directly reveal to us our relationship to it, if our hearts fail to tell us what we owe ourselves and others, we shall assuredly not learn it from books, which are at best designed but to give names to our errors.

Nothing is more consonant with Nature than that she puts into operation in the smallest detail that which she intends as a whole.

Is not the core of nature in the heart of man?

Enjoy when you can, and endure when you must.

There is nothing in life so irrational, that good sense and chance may not set it to rights; nothing so rational, that folly and chance may not utterly confound it.
