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

If people think Nature is their friend, then they sure don’t need an enemy.

Men argue, nature acts.

Nature’s rules have no exceptions.

Animals are such agreeable friends—they ask no questions, they pass no criticisms.

The temple bell stops but I still hear the sound coming out of the flowers.

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

Nature never breaks her own laws.

Those things are better which are perfected by nature than those which are finished by art.

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

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

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

Animals hear about death for the first time when they die.
