Only nature

"This confirmed me in my resolve to keep to Nature alone in future. Only Nature has inexhaustible riches, and only Nature creates a great artist." - Goethe, The Sorrows of Young Werther (Penguin classic, p.32)

Turner wanting future generations to know nature through his work.

Pollock's somewhat defiant declaration: "I am nature" (made in response to a query if he worked from nature). In the context of Dante's statement that art is the child of nature, and thus the grandchild of God, Pollock seems blasphemous. In the context of the Origin of Species, he seems merely accurate.
