But even a course of systematic instruction in the principles of conduct, no matter by what sanctions these principles are inculcated, will not avail much unless they are to some extent practised in the home.  And this will never be the case so long as women are demoralised by the hard conditions of industrial life, and unfitted for the duties of motherhood before beginning to undertake them.

In addition to this, no State will ever get rid of the criminal problem unless its population is composed of healthy and vigorous citizens.  Very often crime is but the offspring of degeneracy and disease.  A diseased and degenerate population, no matter how favourably circumstanced in other respects, will always produce a plentiful crop of criminals.  Stunted and decrepit faculties, whether physical or mental, either vitiate the character, or unfit the combatant for the battle of life.  In both cases the result is in general the same, namely, a career of crime.

As to the best method of dealing with the actual criminal, the first thing to be done is to know what sort of a person you are dealing with.  He must be carefully studied at first hand.  At present too much attention is bestowed on theoretical discussions respecting the various kinds of crime and punishment, while hardly any account is taken of the persons who commit the crime and require the punishment.  Yet this is the most important point of all; the other is trivial in comparison with it.  If crime is to be dealt with in a rational manner and not on mere a priori grounds, our minds must be enlightened on such questions as the following:  What is the Criminal?  What are the chief causes which have made him such?  How are these causes to be got rid of or neutralised?  What is the effect of this or that kind of punishment?  These are the momentous problems; in comparison with these, all fine-spun definitions respecting the difference between one crime and another are mere dust in the balance.  There can be little doubt that a neglect of those considerations on the part of many magistrates and judges, is at the root of the capricious sentences so often passed upon criminals.  The effects of this neglect result in the passing of sentences of too great severity on first offenders and the young; and of too much leniency on hardened and habitual criminals.  Leniency, says Grotius, should be exercised with discernment, otherwise it is not a virtue, but a weakness and a scandal.

When imprisonment has to be resorted to, it must be made a genuine punishment if it is to exercise any effect as a deterrent.  The moment a prison is made a comfortable place to live in, it becomes useless as a safeguard against the criminal classes.  This is a fundamental principle.  But punishment, although an essential part of imprisonment, is not its only purpose.  Imprisonment should also be a preparation for liberty.  If a convicted man is as unfit for social life at the expiration of his
