Most executives, many scientists, and almost all business school gradu — 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."

"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."

"I think there is a danger with young people of being dependent in the sense that they dont acquire any identity or self-image of themselves as thinkers. They just go and look it up or they just chat with someone. In other words, relying on something rather than saying: "Okay, Ive got the information, how do I create value from it?"

"Instead of striving to be right at high cost, it will be more appropriate to be flexible and plural at a lower cost. If you cannot accurately predict the future then you must flexibly be prepared to deal with various possible futures."

"Lateral thinking is closely related to insight, creativity and humour. All four processes have the same basis. But whereas insight, creativity and humour can only be prayed for, lateral thinking is a more deliberate process. It is as definite a way of using the mind as logical thinking — but a very different way."

"Unhappiness is best defined as the difference between our talents and our expectations."

"We have created a wealthy society with tens of millions of talented, resourceful individuals who play virtually no role whatsoever as citizens. Bringing these people in — with their networks of influence, their knowledge, and their resources — is the key to creating the capacity for shared intelligence that we need to solve our problems."

"As in respect of the first wonder we are all on the same level, how comes it that the philosophic mind should, in all ages, be the privilege of a few? The most obvious reason is this: The wonder takes place before the period of reflection, and (with the great mass of mankind) long before the individual is capable of directing his attention freely and consciously to the feeling, or even to its exciting causes. Surprise (the form and dress which the wonder of ignorance usually puts on) is worn away, if not precluded, by custom and familiarity."

"The dualistic philosophy reigned supreme in Europe, dominating the development of Western science. But with the advent of atomic physics, findings based on demonstrable experiment were seen to negate the dualistic theory, and the trend of thought since then has been back to the monistic conception of the ancient Taoists."

"Under the rule of a repressive whole, liberty can be made into a powerful instrument of domination. The range of choice open to the individual is not the decisive factor in determining the degree of human freedom, but what can be chosen and what is chosen by the individual."

"All economic activity is carried out through time. Every individual economic process occupies a certain time, and all linkages between economic processes necessarily involve longer or shorter periods of time."

"I believe that the main lesson which our generation has learnt is that we must find a new limit for the activities of government, a limit which leaves ample scope for sensible experimentation but which secures the freedom of the individual as the mainspring of all social and political activity. The whole purpose of these lectures has been to suggest that we can find such a limit if we are willing to revive and develop the ancient ideal of the Rule of Law."
