If you're interested in learning what the brain does without having to memorize lists of neurotransmitters and sections of neo-cortex, this is the book for you. De Bono is a genius at making a complex subject completely accessible to the average reader. For example, he avoids involved anatomical terminology altogether by using the metaphor of an octopus in place of a neuron. Learning how the brain works by imagining a beach full of glowing, smelly octopuses is a more efficient mnemonic device than a dry, "scientific" treatment. The rest of the book addresses the problems we humans have in trying to deal with everything "logically" without real logical tools, and thinking that everything can be "solved" through language, analysis, and confrontation. My way of thinking was enriched by De Bono's introduction of paradox, humor, and intuition to provoke creative thinking. And he takes on more than a few of philosophy's sacred cows while he's at it. The idea of "catchment" as a model of our automatic compartmentalization of new data is alone worth the price of the book.
