Yeah. It reminds me of questions like what if, 5 seconds from now, I will be Britney Spears?. I'm a little unclear on exactly what parts of "you" continue into the next incarnation (metaphors like "a lamp lighting another lamp" are not very precise)---I think you don't get memories, but you do get mental habits and inclinations?
I could imagine a Less Wronger taking the position that "supposing for the sake of argument that everything in Buddhist metaphysics is correct, the similarities between two reincarnations are not great enough to preserve your personal identity in the philosophical/moral/my-utility-function sense. So you have no reason to care more about your future incarnation than about any other person".
Furthermore, I could also imagine a Buddhist making that argument. Two recurring themes seem to be that it's bad to focus on what you want, and that in fact you should abandon the idea that there is a "you" that wants things. If you follow that advice it seems you should not care about what will happen to "your" reincarnation in particular.
I'm afraid I haven't properly designed the Muggles Studies course I introduced at my local Harry Potter fan club. Last Sunday we finally had our second class (after wasted months of insistence and delays), and I introduced some very basic descriptions of common biases, while of course emphasizing the need to detect them in ourselves before trying to detect them in other people. At some point, which I didn't completely notice, the discussion changed from an explanation of the attribution bias into a series of multicultural examples in favor of moral relativity. I honestly don't know how that happened, but as more and more attendants voiced their comments, I started to fear someone would irreversibly damage the lessons I was trying to teach. They basically stopped short of calling the scientific method a cultural construct, at which point I'm sure I would have snapped. I don't know what to make of this. Some part of me tries to encourage me and make me put more effort into showing these people the need for more reductionism in their worldview, but another part of me just wants to give them up as hopeless postmodernists. What should I do?
