Lateral thinking is concerned not with playing with the existing pieces but with seeking to change those very pieces. It is concerned with the perception part of thinking. This is where we organise the external world into the pieces we can then 'process'.
Edward de BonoIn a sense, words are encyclopedias of ignorance because they freeze perceptions at one moment in history and then insist we continue to use these frozen perceptions when we should be doing better.
Edward de BonoThis new meta-system is very much in favor of the self, but a self that is based on a proper sense of dignity, not on an inflated ego. A person who dare not admit he is wrong inflates his ego but weakens his self.
