I know I haven't been able to post often here, as life has been incredibly busy, so I feel a little guilty that this would be one of my first posts in quite awhile, but, c'est la vie!
I enjoyed this exchange and appreciate the research you have put in, but my only quibble with this is setting up science as in the manner you have here. We have to remember that science only provides enough information in the sense that we can observe that something happens with enough frequency and order to declare it reliably accurate.
Not an absolute truth or known.
Forgive my quibbling as well, as it's not personal, but Scientism is something that can easily creep into our search for pleasure (nay, all stated end goals of various philosophical schools) if we let it.
It does. The science shows everyone IS a psychological hedonist , and the science is what is empirically known. He or she may deny the science, like a creationist denying evolution, but that's what's actually true.
