It's probably easier to see the madness in others. Not so easy to see it in ourselves. Although if we were honest with ourselves, we could document our own endless string of little madnesses in detail. I was recently sitting at a table with a confirmed looney, and two other folks. Four of us. And really we represented a spectrum of madness.
How closely do you want to look? How deeply do you want to probe? Logic, and reason, and common sense? These things seem skin-deep. Get past the surface calm and you will find a boiling cauldron of wildness.
The "confirmed looney," lives in the local nuthouse. He knows he is considered to be a madman. But sitting at that table over a cup of java, he seemed reasonable, funny, interesting. My other two companions? They seemed like the crazy ones. And as for me? I know I've got some irrationalities that totally consume me.
Who spins out? Who gets violent? Who stops being able to maintain? Is it all luck and circumstance? How many slings and arrows push one into the crazy column? I sat at that table thinking about craziness and the things that make us crazy. No clear lines. A spectrum, a rainbow!
