All that's known is this: there is no central processor, no single computer. Nothing that simple. Millions of neurons process information simultaneously and in parallel, not linearly, but the actual chemistry and electrical properties of that integrative process are still being mapped. Even so, it seems odd that during the evolution of brain circuitry and thinking, the ability to understand itself did not get wired in. Such built-in innocence seems like a terrible oversight.

Everything in nature invites us constantly to be what we are.

Ritual which could entail a wedding or brushing one's teeth goes in the direction of life. Through it we reconcile our barbed solitude with rushing, irreducible conditions of life.

Survival is as much a matter of grace as fight. The expression, 'grace under pressure' implies the attainment of equanimity and equilibrium. The fundamental durability of the human body surprises us because the pain can be so intense - yet pain is often transient and hides the tremendous effforts the body is engaged in to heal itself.

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.

The fog lifted in the evening and a blue-black band at the horizon marked the end of the sea and the beginning of thought. Where does a beginning begin when nothing has gone on before?

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.
