The Book of Taboo is perhaps the best known of Alan Watts' books. In it, the author explores an unrecognized, but quite strong taboo - our conspiracy of silence around knowledge of who or what we really are. This is an attempt to answer the question: if our sense of ourselves as a separate ego in a bag of leather is an illusion that corresponds neither to the latest discoveries of Western science nor to the experimental philosophy-religion of the East, then what is our true nature? Immersing the reader in the atmosphere contemplative philosophy and giving a modern twist to ancient teachings, the author offers him a psychological way of realizing that that indefinable idea-feeling that we call “I” is in fact the source and foundation of the Universe.
