Lateral thinking : creativity step by step
(Book)

"This book is intended for use both at home and at school. At school the emphasis has traditionally always been on vertical thinking which is effective but incomplete. This book is about lateral thinking which is the process of using information to bring about creativity and insight restructuring. Lateral thinking can be learned, practiced and used. It is impossible to acquire skill in it just as it is possible to acquire skill in mathematics."--From back cover.
