Humour is by far the most significant activity of the human brain. - Edward de Bono

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 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.

The concept of lateral thinking is insight restructuring and this is brought about through the rearrangement of information. Rearrangement is the basis of lateral thinking and rearrangement means escape from the rigid patterns established by experience. The rearrangement process is incorporated in the concept of the (re) laxative. The laxative is a rearranging device. It is the means whereby one can escape from established patterns and create new ones. The laxative allows the arrangement of information in new ways from which new patterns can arise. The concept of the laxative is crystallized into a definite language tool. This language tool is PO. Once one learns the function and use of PO one has learned how to use lateral thinking. The whole concept of lateral thinking is concentrated in the use of this language tool. Lateral thinking could be said to be the management of PO just as logical thinking is the management of NO.
