Tyler Cowen argues in a TED talk (~15 min) that stories pervade our mental lives. He thinks they are a major source of cognitive biases and, on the margin, we should be more suspicious of them - especially simple stories. Here's an interesting quote about the meta-level:
What story do you take away from Tyler Cowen? ...Another possibility is you might tell a story of rebirth. You might say, "I used to think too much in terms of stories, but then I heard Tyler Cowen, and now I think less in terms of stories". ...You could also tell a story of deep tragedy. "This guy Tyler Cowen came and he told us not to think in terms of stories, but all he could do was tell us stories about how other people think too much in terms of stories."
I cannot make any strong statements about how my preferences would change if I learned for sure that I definitely cannot exert any permanent effect on reality. The question does not interest me. Also, the current me does not sympathize with any hypothetical me who is stuck in a reality on which he cannot exert any permanent effect. He is a non-person to me. (Yeah, I can be pretty callous towards future versions of myself. But it is not like I can rescue him from his (hypothetical) predicament.)
Finally, and this is nothing personal, Doug, but I will probably not take the time to answer future questions from you on this subject because I have resolved to stop trying to convert anyone to any particular moral position or system of valuing things, and this question I just answered pulled me back into that frame of mind for a couple of hours.
No problem. I was just confused because "avoid pain" seems to be a goal built into most neurologically intact people at a fairly basic level (even lizard brains try to avoid pain), and that, in that context, seeing someone say that they don't care to avoid transient pain strikes me as an extremely bizarre thing to say.
