'Jaap van Ginneken is a major voice in political psychology. This book richly documents how leaders are inevitably corrupted by power, proving Lord Acton's saying that 'great men are almost always bad men'. If we need great men for their greatness, we must hence always guard against their darkness'. -Dick Pels, former Professor of Sociology & Communications, Brunel University, UK ...

But there is still a huge reluctance from the powerful to admit that there can be an inner intoxication which they do not control. Millions of pounds are spent on researching risk factors in banking and business with complicated models and statistical analysis. What is missing is a large contribution from the biological and social sciences. This book written by a psychologist has the virtue of being written in an attractive, arresting style with compelling case histories.' - Lord David Owen, former British Foreign Secrtary 'Whenever a new book by Jaap van Ginneken gets into my hands, it completely messes up my work schedule - as I am captivated as soon as I open it. With this topical book it was the same again. Recommended!'. - Pieter J. van Strien, former Professor of Psychology, Groningen University, the Netherlands Show Less
