I crave and seek a natural explanation of all phenomena upon this earth, but the word 'natural' to me implies more than mere chemistry and physics. The birth of a baby and the blooming of a flower are natural events, but the laboratory methods forever fail to give us the key to the secret of either.

Without the emotion of the beautiful, the sublime, the mysterious, there is no art, no religion, no literature.

The love of nature is a different thing from the love of science, though the two may go together.
