The period in French prison practice treated in this volume is one of transition between the end of the Old Régime and the beginning of the New. It presents first a view of the prisons of the period immediately following the Revolution, and concludes with the consideration of a great model penitentiary, which may be said to be the “last word” in the purely physical aspects of the whole question, while its very perfection of structure and equipment gives rise to important moral questions, which must dominate the future of prison conduct. Throughout the first half of the nineteenth century the combat with the great army of depredators was unceasingly waged by the champions of law and order in France, to whom in the long run victory chiefly inclined. As yet none of the new views held by prison reformers in other countries had made any progress in France. No ideas of combining coercion with persuasion, of going beyond deterrence by attempting reformation by exhortation; of curing the wrong-doer and weaning him from his evil practices, when once more sent out into the world, obtained in French penology. At that earlier date all the old methods, worked by the same machinery, still prevailed and were, as ever, ineffective in checking crime. An active, and for the most part intelligent police was indefatigable in the pursuit of offenders, who, when caught and sentenced travelled the old beaten track, passing from prison to prison, making long halts at the bagnes and concluding their persistent trespasses upon the guillotine, but that was all. French prisons long lagged behind advanced practices abroad, not only in respect of their structural fitness and physical condition, but also in the measure in which the method of conducting them effected the morals of those who passed through them. When the question was at last presented, it was considered with the logical thoroughness and carried out with the administrative efficiency characteristic of the French government, when impressed with the necessity for action in any given line. The question for the French prison authorities—as indeed it is the question of questions for the prison government of all nations—is now: “What can be and shall be done for the reform of the convict rather than for his mere repression and punishment?” The material aspects of the French prison system have attained almost to perfection. These, as well as the moral aspects of the subject, which that very physical perfection inevitably presents, it is the purpose of this volume to consider.
