Vertical thinking is selection by exclusion. One works within a frame of reference and throws out what is not relevant. With lateral thinking one realizes that a pattern cannot be restructured from within itself but only as the result of some outside influence. So one welcomes outside influences for their provocative action. The more irrelevant such influences are the more chance there is of altering the established pattern. To look only for things that are relevant means perpetuating the current pattern.

Rightness is what matters in vertical thinking. Richness is what matters in lateral thinking. Vertical thinking selects a pathway by excluding other pathways. Lateral drinking does not select but seeks to open up other pathways. With vertical thinking one selects the most promising approach to a problem, the best way of looking at a situation. With lateral thinking one generates as many alternative approaches as one can.
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
Some communities will be abandoned, others will struggle along, others will split, others will flourish, gain members, and be duplicated elsewhere. Each community must win and hold the voluntary adherence of its members. No pattern is imposed on everyone, and the result will be one pattern if and only if everyone voluntarily chooses to live in accordance with that pattern of community.
Robert Nozick
It becomes bars! The outside pattern, I mean, and the women behind it is as plain as can be. I didn't realize for a long time what the thing was that showed behind, that dim sub-pattern, but now I am quite sure it is a woman. By daylight she is subdued, quiet. I fancy it is the pattern that keeps her so still.
Charlotte Perkins Gilman
A pattern has an integrity independent of the medium by virtue of which you have received the information that it exists. Each of the chemical elements is a pattern integrity. Each individual is a pattern integrity. The pattern integrity of the human individual is evolutionary and not static.
