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
"everything in the garden to be lovely." 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.
