The Homunculus

steveSteve Higgins is a psychology graduate student at an online university. He hopes that the three weeks and $29.95 that he is spending on his Ph.D. will get him a job at a Tier 1 research university. Do online universities have postdocs? Ok...just kidding, Steve is a real graduate student at a real school.

I heard about this years ago in a psychology class. There was a specific example of two very disparate things shown to the two different eyes. I wish I could remember the example, because at the end when the person tested was asked why the hand drew one thing but he said another with his voice, he gave a completely rational explanation as to why his hand might have drawn something that didn't seem to fit.

What the neuroscientist here describes as the last step that has to generate a consistent theory of what's going on in our mind is what I call the "bullshit generator," that tries to rationalize why all the product of all our vaguely independent subsystems or agents are "really" consistently after all. "Really, I'm an individual!"

This makes me wonder what other people would do if they were presented with the dilemma of either one condition or another to live with. If a doctor said to you that you have a life threatening condition, would you be willing to live as this man does instead? I'm sure it would be tremendously confusing for him.
