Few quotations from Karl Marx's writings demonstrate more clearly how low one can sink into a theoretical pit in order to explain the existence of crimes, criminality, and a penal system from the perspective of the state. Taken literally and transferred onto the field of the history of confinement in general, Marx's aperçu would mean not only that the criminal produced the prison, but that the patient created the hospital and the mentally ill invented the insane asylum. Being a trained jurist, Marx of course had a theory on crime and criminality, but it tended to be explicit only in areas such as property law, whereas the lower classes- les gens sans feu et sans aveu, the classes dangereuses, or the Lumpenproletariat - were nothing more than aberrant proletarians who had sunk into what Marx called the bohème. He even speaks of “this passive rot of the lowest strata of the old society” and predicts that, at best, this part of society has a tendency to form an alliance with reactionaries.
