The day should come when all of the forms of life... will stand before the court - the pileated woodpecker as well as the coyote and bear, the lemmings as well as the trout in the streams.

Naturalists, like poets, are born and then made only by years of painstaking observation.

To the great tree-loving fraternity we belong. We love trees with universal and unfeigned love, and all things that do grow under them or around them - the whole leaf and root tribe. Not alone when they are in their glory, but in whatever state they are - in leaf, or rimed with frost, or powdered with snow, or crystal-sheathed in ice, or in severe outline stripped and bare against a November sky - we love them.

When you get into the whole field of exploring, probably 90 percent of the kinds of organisms, plants, animals and especially microorganisms and tiny invertebrate animals are unknown. Then you realize that we live on a relatively unexplored plan.

In traditional societies, nature was seen as one’s wife, but the modern West turned it into a prostitute.

The more you go on, the less you need people standing between you and the animal and the camera waving their arms about.
