There is not a sprig of grass that shoots uninteresting to me.

Drive out nature with a pitchfork, and she will always come back. 

God writes the Gospel not in the Bible alone, but on trees and flowers and clouds and stars.

Nature’s rules have no exceptions.

We never are definitely right; we can only be sure we are wrong.

A tree’s a tree. How many more do you need to look at?

I always think of nature as a great spectacle, somewhat resembling the opera.
