That may sound philosophical or even religious, but we really have to think like this at the dawn of genetic engineering. The practical applications are immense. We are beginning to engineer our very selves, to see our subjective ways of framing reality and being in the world as modular objects to be manufactured and enhanced. In the next century, it's going to be bootstrapping big time for the human species as we see ourselves as an image in our own collective mind, an image to be designed and executed. Not exactly a computer program, but something very like.
Subjectivity is hardwired into our brains.
But think about this. A patient with a brain disorder was being probed with electric needles. Doctors were hoping to locate areas of the brain that were the source of her seizures. I remembered a friend experimenting with hallucinogens. He couldn't stop laughing at the spectacle of role-playing human beings acting as if their social masks were real.
