I like to bounce back and forth between the really practical and the really theoretical when discussing prison policy. Something that definitely falls on the extremely theoretical end are centuries old and centuries long changes in penal practices. In the 18th century, and execution might have ended something like this:
After two or three attempts, the executioner Samson and he who had used the pincers each drew out a knife from his pocket and cut the body at the thighs instead of severing the legs at the joints; the four horses gave a tug and carried off the two thighs after them, namely, that of the right side first, the other following; then the same was done to the arms, the shoulders, the arm-pits and the four limbs; the flesh had to be cut almost to the bone, the horses pulling hard carried off the right arm first and the other afterwards.
Read the whole thing, it’s pretty great. In any case, an execution was a grisly spectacle in the public square, and also something resembling must-see TV for people in the town. Just a hundred years later, things were much more civilized and orderly. By the late 19th century, a criminal was either detained and segregated, or detained, segregated and put to work:
Art. 20. Work. At a quarter to six in the summer, a quarter to seven in winter, the prisoners go down into the courtyard where they must wash their hands and faces, and receive their first ration of bread. Immediately afterwards, they form into work-teams and go off to work, which must begin at six in summer and seven in winter.
(Foucault details a whole routine that prisoners had to go through during the day). As Foucault states, there was a change in the mentality accompanying punishment, which marched along in tandem with advances in the justice system such as the addition of jury trials, and additional due process:
And yet the fact remains that a few decades saw the disappearance of the tortured, dismembered, amputated body, symbolically branded on face or shoulder, exposed alive or dead to public view. The body as the major target of penal repression disappeared.
This also in many ways signified the turn from a deterrence/retribution model to a rehabilitation/segregation model. But was this driven by some underlying change in the barbarian nature of humanity, or simple logistics? In the 18th century it would have been impossible and counterproductive to facilitate productive or segregatory punishment for the tens of thousands of people who committed crimes. Better to either execute them or scare the shit out of them and let them go.
By the 19th century, you could transport, keep track of, and lodge thousands of people in little cities.
Once it becomes an option to not have to rip people limb from limb, that option becomes pretty appealing and societies tend to change their thinking along with that. The whole idea of retribution in the form of killing people appears “barbaric” and we’re looking at segregation and rehabilitation as the right things to do.
But now that a lot of the arguments for deterrence appear to have fallen by the wayside, and as a society we’re loathe to admit that we are actually using segregation (because it’s inefficient and stupid), where is the balance between humanity and barbarianism in the whole deterrence thing? Deterrence seems to be a primary and acceptable argument for super long sentences and also the death penalty. Maybe the way to go here is to look to the past and make things less humane. Or, with the awfulness of prison conditions at the moment, are we already heading that way?
