True solace is finding none, which is to say, it is everywhere.

Honesty is stronger medicine than sympathy, which may console but often conceals.

The retreat and disappearance of glaciers—there are only 160,000 left—means we're burning libraries and damaging the planet, possibly beyond repair. Bit by bit, glacier by glacier, rib by rib, we're living the Fall.

History is not truth versus falsehoods, but a mixture of both, a mélange of tendencies, reactions, dreams, errors, and power plays. What's important is what we make of it; its moral use. By writing history, we can widen readers' thinking and deepen their sympathies in every direction. Perhaps history should show us not how to control the world, but how to enlarge, deepen, and discipline ourselves.

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.

Perhaps despair is the only human sin.
