Creative thinking — in terms of idea creativity — is not a mystical talent. It is a skill that can be practised and nurtured. You can never tell how … - Edward de Bono

Lateral thinking... is the process of using information to bring about creativity and insight restructuring. Lateral thinking can be learned, practised and used. It is possible to acquire skill in it just as it is possible to acquire skill in mathematics.

What happened was, 2,400 years ago, the Greek Gang of Three, by whom I mean Aristotle, Plato and Socrates, started to think based on analysis, judgment and knowledge. At the same time, church people, who ran the schools and universities, wanted logic to prove the heretics wrong. As a result, design and perceptual thinking was never developed. People assumed philosophers were doing it and so they blocked anyone else from doing it. But philosophers were not. Philosophers may look out at the world from a stained-glass window, but after a while they stop looking at the world and start looking at the stained glass.

Studies have shown that 90% of error in thinking is due to error in perception. If you can change your perception, you can change your emotion and this can lead to new ideas.
