There has never been a book like this before. Not only is The Tyranny of Ambiguity an engaging story, the author proposes a system which forms a basis for the complete understanding of human behaviour. It is a major advance in human understanding.

The book begins with accounts of a series of experiments into basic mating strategies which took place on the streets of Amsterdam. The narrative is alternated by theoretical sections as the theories, such as a breakdown of the costs and benefits of sex, develop from the experimental evidence.

Many psychological phenomena are detailed but one given particular attention is neurosis, defined in this system as the condition which arises when one stimulus evokes two or more responses. The analysis displays a refreshing clarity, far surpassing historical attempts to detail this essential mechanism.
