Edward de Bono on the interaction between creativity and logic:
…every valuable, creative idea will always be logical in hindsight. If an idea were not logical in hindsight, then we would never be able to appreciate the value of the idea. The idea would remain valueless. So we are only able to appreciate those creative ideas that are indeed logical in hindsight. Then we go on to say — as we have been doing for 2,400 years — that if an idea is logical in hindsight, then better logic should have found it in the first place. So we try to teach more logic instead of taking creativity seriously.
Or as James says, “That’s Common Sense You Didn’t Have 6 Months Ago.“
