What Flaubert refers to as the “mélancholies du voyage” is like the sadness I feel as one season departs and another arrives.

Love life first, then march through the gates of each season; go inside nature and develop the discipline to stop destructive behavior; learn tenderness toward experience, then make decisions based on creating biological wealth that includes all people, animals, cultures, currencies, languages, and the living things as yet undiscovered; listen to the truth the land will tell you; act accordingly.

Thirty years ago, my sister, Gale (so named because a gale hit Boston Harbor the night she was born), some friends and I stole a boat in the middle of the night and sailed it out of the Santa Barbara harbor. Suddenly we were becalmed and the current began pushing us toward the breakwall. With no running lights and no power, we were dead in the water. Out of that darkness a steel hull appeared: it was the local Coast Guard cutter. My father, stern-faced and displeased, stood in the bow.

To trace the history of a river . . . is to trace the history of the soul, the history of the mind descending and arising in the body.

A tree is an aerial garden, a botanical migration from the sea, from those earliest plants, the seaweeds; it is a purchase on crumbled rock, on ground. The human, standing, is only a different upsweep and articulation of cells. How treelike we are, how human the tree.

I like to think of the landscape not as a fixed place but as a path that is unwinding before my eyes, under my feet. To see and know a place is a contemplative act. It means emptying our minds and letting what is there, in all its mulitplicity and endless variety, come in.

The truest art I would strive for in any work would be to give the page the same qualities as earth: weather would land on it harshly; light would elucidate the most difficult truths; wind would sweep away obtuse padding.
