Robert Hare has delivered a fascinating insight into the terrifying world of the psychopath. Without Conscience is aimed at the layperson, as opposed to the academic, and is pitched perfectly. It is detailed enough to properly explain and simple enough to be intelligible to the average reader. A concise background to the condition sets the scene before the main traits of the psychopath are revealed and explained along with pertinent anecdotes to demonstrate how these traits operate in practice. Hare also explores psychopathy in children and young adults, charting their development to adulthood as well as the pernicious influence of non-criminal psychopaths in the workplace. This book is of particular importance because it brings the danger of psychopaths to the everyday reader who may well suffer at their hands in future, if they have not already. It appears that the public are largely ignorant to the extent of the threat posed by psychopaths because of ignorance to what a psychopath is, how many of them are out there and their incredible ability to appear to be what they are not. Hare provides some strategies to combat the effect of psychopaths at close hand. While less than cast-iron (due to the nature of the disorder, not Hare’s writing) they might provide some assistance to people trying to cope with, or escape from one. Hare goes on to mention how research is developing strategies to limit the negative behaviour of psychopaths. I look forward to reading the results in years to come. A highly recommended read for anyone looking for a beginners insight to psychopathy or has been victimised by a psychopath.
