I cannot better give Professor Prins’s opinion upon the subject of my work than by quoting what he says in his book, “Criminalité et répression”, and especially in his first chapter entitled “De la criminalité en général. Des classes criminelles. Des délinquants d’accident et des délinquants de profession.” There we read: “There exists no abstract type of a moral man, nor of a guilty man; crime is not an individual phenomenon, but a social phenomenon. Criminality proceeds from the very elements of humanity itself; it is not transcendent, but immanent; we can see in it a sort of degeneration of the social organism.” [179] There is an environment favorable to moral health, where the tendency to crime is almost wholly lacking; there is a social environment where the atmosphere is corrupt, where unwholesome elements are heaped up, where the most vigorous perish, where criminality spreads like the mould in the dunghill; the tendency toward crime there is formidable, and we can say in this sense that it is a social fact with a social cause, and that it is in intimate connection with a given social organization. Let us consider our own epoch for a moment. A century of progress and refinement is a century of vices; the increasing complexity of our mechanism creates, with new temptations, new occasions of falling. The car of civilization, like that of Juggernaut, destroys many of those who throw themselves under its wheels. The world has enormous appetites that it cannot satisfy: sensuality, greed of gain, a taste for and facility in speculation; the contrast between great wealth and extreme poverty; the brutal necessities of the struggle for existence in the face of the concentration of property and of capital; the defects of the industrial organization, which abandons the proletariat to chance, keeps no watch over apprenticeship, and leaves the child of the working-man to the excitations of the streets and the promiscuity of the workshop, and finally sharpens everywhere the obscure instincts of animalism; all this recoils upon criminality with deplorable certainty. How far wrong we should be in such an environment simply to contrast the delinquent with the honest man! It is two social states that are contrasted; the one is based upon comfortable means, sociability, mutual protection, useful work, and thrift; the other upon poverty, isolation, egoism, and unproductive labor. And in the great urban agglomerations, pauperism, mendicity and vagrancy, idleness, the spirit of adventure, prostitution, the dissipation of strength, everything, in short, naturally concurs in developing social anemia.
