This is one of the best books I have read. It does not describe the mind in neurochemical or psychological terms, but hits the spot by providing a simple model of how the mind works. From that model, De Bono provides insight on how memory, learning, attention, 'pig-headedness' and insight can occur. He shows how the brain stores information and experience efficiently, but also shows how those storage units can become rules unto themselves, thereby inhibiting further clear thinking. He then describes lateral thinking, as a means of disrupting the learnt rigid patterns that can make people blind to the simplest of ideas. It is curious that this work is not more extensively discussed in texts on psychology. Those texts often describe research on how certain neurons in the brain become selected through use, but do not take the simple step back to this original work by De Bono. Another interesting interpretation of the De Bono work is provided in Cookson's book 'Our wild niche', where he coins the word mindrules (similar to De Bono's d-lines). Mindrules are experience learnt instincts, and have wider connotations for human ecology and adjustment to various niches, both natural and artificial. I recommend you buy the Mechanism of Mind. Then you will almost see how the cogs in your own mind turn. awilliams73@hotmail.com
