TGGP: why are you opposed to the idea that we may want to retain parts of pain?
If we could get rid of the ‘painfulness’ of pain, and keep the informative part of pain, that’d be ideal. With no pain at all, we’re in the situation of someone with nerve damage who might lose a limb to gangrene when she accidentally damages something but doesn’t notice it. (Anyone for The Chronicles of Thomas Covenant, the Unbeliever?)
Painless pain isn’t all that strange an idea:
’The second pain pathway is a much more recent scientific discovery. It runs parallel to the sensory pathway, but isn’t necessarily rooted in signals from the body. The breakthrough came when neurologists discovered a group of people who, after a brain injury, were no longer bothered by pain. They still felt the pain, and could accurately describe its location and intensity, but didn’t seem to mind it at all. The agony wasn’t agonizing.
This strange condition—it’s known as pain asymbolia—results from damage to a specific subset of brain areas, like the amygdala, insula and anterior cingulate cortex, that are involved in the processing of emotions. As a result, these people are missing the negative feelings that normally accompany our painful sensations. Their muted response to bodily injury demonstrates that it is our feelings about pain—and not the pain sensation itself—that make the experience of pain so awful. Take away the emotion and a stubbed toe isn’t so bad.′ http://scienceblogs.com/cortex/2009/01/back_pain.php
Brandon: If we’re still discussing possible failures, I’d like to chuck in one of my own.
They didn’t know that they were looking for a better theory.
The students in this story have the incredible advantage that they are starting from a wrong theory and know this for certain, and not merely suspect or hold as a general philosophy-of-science principle ‘there’s probably a better theory than the current one’. This gives them several things psychologically: 1) the willingness to scrap painfully won insights and theories in favor of something new and 2) saves them from spending all their time and effort patching up the old theory.
I know in the past when I’ve tried my hand at problems (logic puzzles come to mind) that I am far more motivated and effective when I am assured that there is in fact a correct answer than when I am unsure the question is even answerable.
