We are all assumed, these days, to reside at one extreme of the opinion spectrum, or another. We are pro-abortion or anti-abortion. We are free traders or protectionists. We are pro-private sector or pro-government. We are feminists or chauvinists. But in the real world, few of us hold these extreme views. There is instead a spectrum of opinion.

It's not easy to cut through a human head with a hacksaw.

The truth is, almost nobody wants to experience real nature. What people want is to spend a week or two in a cabin in the woods, with screens on the windows. They want a simplified life for a while, without all their stuff. Or a nice river rafting trip for a few days, with somebody else doing the cooking. Nobody wants to go back to nature in any real way, and nobody does. It's all talk.

All human behavior has a reason. All behavior is solving a problem.

Cut off from direct experience, cut off from our own feelings and sometimes our own sensations, we are only too ready to adopt a viewpoint or perspective that is handed to us, and is not our own.

The fact that the patients were complex human beings with a rich life beyond the hospital never really sank into the consciousness of the residents. Because they had no rich lives beyond the hospital, they assumed no one else did, either. In the end, what they lacked was not medical knowledge but ordinary life experience.

For our own species, evolution occurs mostly through our behavior. We innovate new behavior to adapt.
