If anything is endemic to Wyoming it is wind. This big room of space is swept out daily, leaving a bone yard of fossils, agates, and carcasses in every stage of decay. Though it was water that initially shaped the state, wind is the meticulous gardener, raising dust and pruning the sage.

Perhaps despair is the only human sin.

I thought: to be tough is to be fragile; to be tender is to be truly fierce.

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.

A black-crowned night heron stood on an apron of wet sand, looking across the channel. The feather plume at the back of his head lifted in a faint breeze. Out there the channel churned its cyclonic eddies counterclockwise. Schools of anchovies, halibut, and sea bass came and went: silver flashes, small storms that well up from the inside of the sea but are short-lived, like lightning.

Finally, the lessons of impermanence taught me this: loss constitutes an odd kind of fullness; despair empties out into an unquenchable appetite for life.

There is nothing in nature that can't be taken as a sign of both mortality and invigoration.
