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

When you have only two pennies left in the world, buy a loaf of bread with one, and a lily with the other.

Nature’s rules have no exceptions.

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

Nature resolves everything into its component elements, but annihilates nothing.

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

Nature is the art of God.
