Remedies for Crime.--The remedies for crime are dealt with by the subsidiary science of penology, which may be regarded as a branch of scientific philanthropy. We can only direct the student's attention here to the vast literature on the subject and remark that the cure for crime consists not in some social panacea or in social revolution, but in dealing with the causes of crime so as to prevent the existence of the criminal class. In a general way, we have already indicated in discussing the remedies for poverty and pauperism what the steps must be to eradicate crime. In order practically to wipe out crime in society, as we have already said, three things are necessary. First, every individual must have a good birth; that is, heredity must be controlled so that only those who are physically and mentally sound are allowed to marry and reproduce. The difficulties of doing this we have already noted. Second, every individual must have a good training, both at home and at school, so as to adjust him properly to the social life. His education must fit him to take his place among other men, make him able to take care of himself, and to help others; and make him, in every possible way, acquainted with the social inheritance of the race. Last but not least, just social conditions must be provided. Everything in the social environment must be carefully looked after in order to insure the best development of the individual and to prevent his environment from being in any way a drawback to him. These things, if it were possible to bring them about, would wipe out crime, or, at least, minimize it to the lowest terms. Of course, this cannot be done in a generation, perhaps not in many generations, but it is evident that the problem of crime is in no way an insoluble problem in human society. With time and care and scientific knowledge, crime, as well as poverty and pauperism, could be wiped out.
