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

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

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

Nature is immovable.

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

Nature never breaks her own laws.

A garden must be looked into, and dressed as the body.
