Couples are jigsaw puzzles that hang together by touching in just enough points. They're never total fits or misfits. In time, a pair invents its own commonwealth, complete with anthems, rituals, and lingos-a cult of two with fallible gods.

We're dabbling in eugenics all the time, breeding ideal crops to replace less aesthetic or nutritious or hardy varieties; leveling forests to graze cattle or erect shopping malls and condos; planting groves of a few familiar trees that homeowners and industries prefer.

Though most of us don't hunt, our eyes are still the great monopolists of our senses. To taste or touch your enemy or your food, you have to be unnervingly close to it. To smell or hear it, you can risk being further off. But vision can rush through the fields and up the mountains, travel across time, country, and parsecs of outer space, and collect bushel baskets of information as it goes. Animals that hear high frequencies better than we do

Poetry is an act of distillation. It takes contingency samples, is selective. It telescopes time. It focuses what most often floods past us in a polite blur.

In our heart we know that life loves life. Yet we feast on some of the other life-forms with which we share our planet; we kill to live. Taste is what carries us across that rocky moral terrain, what makes the horror palatable, and the paradox we could not defend by reason melts into a jungle of sweet temptations.

We tend to think of memories as monuments we once forged and may find intact beneath the weedy growth of years. But, in a real sense, memories are tied to and describe the present. Formed in an idiosyncratic way when they happened, they're also true to the moment of recall, including how you feel, all you've experienced, and new values, passions, and vulnerability. One never steps into the same stream of consciousness twice.
