introduction to the study of criminal questions in general. In spite
of all the attention these questions have hitherto received and are
now receiving, crime still remains one of the most perplexing and
obstinate of social problems. It is much more formidable than
pauperism, and almost as costly. A social system which has to try
hundreds of thousands of offenders annually before the criminal courts
is in a very imperfect condition; the causes which lead to this state
of things deserve careful consideration from all who take an interest
in social welfare.

In the following pages I have endeavoured to show that crime is a more
complicated phenomenon than is generally supposed. When society will
be able to stamp it out is a question it would be extremely hard to
answer. If it ever does so, it will not be the work of one generation
but of many, and it will not be effected by the application of any
single specific.

Punishment alone will never succeed in putting an end to crime.
Punishment will and does hold crime to a certain extent in check, but
it will never transform the delinquent population into honest
citizens, for the simple reason that it can only strike at the
full-fledged criminal and not at the causes which have made him so.
Economic prosperity, however widely diffused, will not extinguish
crime. Many people imagine that all the evils afflicting society
spring from want, but this is only partially true. A small number of
crimes are probably due to sheer lack of food, but it has to be borne
in mind that crime would still remain an evil of enormous magnitude
even if there were no such calamities as destitution and distress. As
a matter of fact easy circumstances have less influence on conduct
than is generally believed; prosperity generates criminal inclinations
