Lateral thinking (横向思维)，first described by Edward de Bono in 1967, is just a few years older than Edwards son. You might imagine that Caspar was raised to be an adventurous thinker, but the de Bono name was so famous, Caspars parents worried that any time he would say something bright at school, his teachers might snap (不耐烦地说), 'Where do you get that idea from?' 'We had to be careful and not overdo it,' Edward admits. Now Caspar is at Oxford—which once looked unlikely because he is also slightly dyslexic (诵读困难). In fact, when he was applying to Oxford, none of his school teachers thought he had a chance. 'So then we did several thinking sessions,' his father says, 'using my techniques and, when he went up for the exam, he did extremely well. ' Soon after, Edward de Bono decided to write his latest book, Teach Your Child How to Think, in which he transforms the thinking skills he developed for brainstorming businessmen into informal exercises for parents and children to share. Thinking is traditionally regarded as something executed in a logical sequence, and everybody knows that children arent very logical. So isnt it an uphill battle, trying to teach them to think? 'You know,' Edward de Bono says, 'if you examine peoples thinking, it is quite unusual to find faults of logic. But the faults of perception are huge! Often we think ineffectively because we take too limited a view. ' Teach Your Child How to Think offers lessons in perception improvement, of clearly seeing the implications of something you are saying and of exploring the alternatives. What is true about Caspar?
