How Pleasure Works. The book offers ample evidence that pleasure is not just a question of nerve endings, but of background beliefs. What you believe can alter how something feels, tastes, sounds. For example, believing that you're hearing a million dollar Stradivarius played by a top violinist will make most people enjoy the music more. So this occurs to me (and occurred to me many times before I read Bloom). Take music like Handel's Messiah. Is it more enjoyable for believers, considering that they really do exult in the Messiah's birth, and non-believers don't? Or do believers and non-believers enjoy it equally? Take the poll, top right.
