Interesting premise, but the way Bloom tries to draw in the reader with a discussion on cannibalism was a little unsettling to start off with. The ideas were interesting but repetitive. The concepts (basically, that objects and pleasures have non-physical essences that we humans care about) as well as the supporting studies Bloom described (such as those about children and intuitive essentialism) made this worth reading, but the quality of writing made it a bit of a drag.
