[Bloom's] most important point is that humans are “born essentialists”. We see everything as possessing “an underlying reality or true nature that one cannot observe directly, and it this hidden nature that really matters”. This is obviously true of people. If I disguise myself, you will not think I have become another person. And in Capgras Syndrome — in which sufferers become convinced that their closest friends and loved ones have been replaced by imposters — it is clear that the mere sight of a person is not enough. Some awareness of an inner essence is also needed.
