Scar tissue has no character. It's not like skin. It doesn't show age or illness or pallor or tan. It has no pores, no hair, no wrinkles. It's like a slip cover. It shields and disguises what's beneath. That's why we grow it; we have something to hide.

Light like this does not exist, but we wish it did. We wish the sun could make us young and beautiful, we wish our clothes could glisten and ripple against our skins, most of all, we wish that everyone we knew could be brightened simply by our looking at them, as are the maid with the letter and the soldier with the hat.

For nearly a century the psychoanalysts have been writing op-ed pieces about the workings of a country they've never traveled to, a place that, like China, has been off-limits. Suddenly, the country has opened its borders and is crawling with foreign correspondents, neurobiologists are filing ten stories a week, filled with new data. These two groups of writers, however, don't seem to read each other's work. That's because the analysts are writing about a country they call Mind and the neuroscientists are reporting from a country they call Brain.

Was everybody seeing this stuff and acting as though they weren't? Was insanity just a matter of dropping the act?

Are you crazy? It's a common phrase, I know. But it means something particular to me: the tunnels, the security screens, the plastic forks, the shimmering, ever-shifting borderline that like all boundaries beckons and asks to be crossed. I do not want to cross it again.

This clarity made me able to behave normally, which posed some interesting questions. Was everybody seeing this stuff and acting as though they weren't? Was insanity just a matter of dropping the act? If some people didn't see these things, what was the matter with them? Were they blind or something? These questions had me unsettled.

I think many people kill themselves simply to stop the debate about whether they will or they won't.
