The title that the authors have chosen for this book, The Causes and Cures of Criminality, suggests that it may be just another book specu- lating on the sociological evils that need to be put right for "e;everything in the garden to be lovely."e; If this is the expectation, the reader could not be more mistaken. The recurrent theme, in fact, is a strong accent on psychological experiments. Both authors have tackled the theoretical and practical side of crime through an exhaustive literature review of past experi- mental work. Hans J. Eysenck has concentrated on the constitutional and biological theory of criminality, whereas Gisli Gudjonsson has con- cerned himself more with a review of ongoing research into therapy and possible prevention of antisocial behavior. Part I goes into considerable detail on the causes of criminality, stressing much of the strangely neglected area of individual differences in personality. Research studies point to a very heavy involvement of heredity in the causation of criminality, but the authors are careful to acknowledge that much can be done environmentally to discourage a life of crime once those persons who are at risk have been identified.
