The concept of logical thinking is selection and this is brought about by the processes of acceptance and rejection. Rejection is the basis of logical thinking.

The rejection process is incorporated in the concept of the negative. The negative is a judgement device. It is the means whereby one rejects certain arrangements of information. The negative is used to carry out judgement and to indicate rejection. The concept of the negative is crystallized into a definite language tool. This language tool consists of the words no and not. Once one learns the function and use of these words one has learned how to use logical thinking. The whole concept of logical thinking is concentrated in the use of this language tool. Logic could be said to be the management of NO.
Edward de Bono
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.
Edward de Bono
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.
Edward de Bono
Every time one combines and records facts in accordance with established logical processes, the creative aspect of thinking is concerned only with the selection of the data and the process to be employed, and the manipulation thereafter is repetitive in nature and hence a fit matter to be relegated to the machines.
Vannevar Bush
Gradually I began to intellectually reject some of the delusionally influenced lines of thinking which had been characteristic of my orientation. This began, most recognizably, with the rejection of politically-oriented thinking as essentially a hopeless waste of intellectual effort.
