In this volume Professor Ferri, a distinguished member of the Italian Parliament, deals with the conditions which produce the criminal population, and with the methods by which this anti-social section of the community may be diminished.  He divides the causes of crime into two great classes, individual and social.  The individual causes consist of physical and mental defects; the social causes consist of social disadvantages of every description.  His view is that the true remedy against crime is to remove individual defects and social disadvantages where it is possible to remove them.  He shows that punishment has comparatively little effect in this direction, and is apt to divert attention from the true remedy—­the individual and social amelioration of the population as a whole.
