We find not only the unsocial, the negatively unfit, those whom society puts away with pity in its heart; there are also the antisocial, the class whom we usually designate as criminals.

These persons, like the others, are variations; but they seem to be variations in quite another way.

They do not represent lack on the intellectual side always or alone, but on the moral side, on the social side, as such.

The least we can say of the criminals is that they tend, by heredity or by evil example, to violate the rules which society has seen fit to lay down for the general security of men living together in the enjoyment of the social heritage.

So far, then, they are factors of disintegration, of destruction; enemies of the social progress which proceeds from generation to generation by just this process of social inheritance.
So society says to the criminal also: "You must perish." We kill off the worst, imprison the bad for life, attempt to reform the rest.
They, too, then, are excluded from the heritage of the past.
So our lines of eligibility get more and more narrowly drawn.
