The Effects of Solitary Confinement on Perception

There is a philosopher that I know at Harvard called Ian Corbin, who has done some nice work on this recently. And essentially what we see is that after people are in solitary confinement for a certain amount of time, they start to lose things that we think are attributable to like full autonomy or individuality. We have cases where someone will stab themselves, and they won't know that the arm that they stabbed is their own. They don't experience it as their own body. It seems to me that kind of thing is pretty strong confirmation for the degree to which when we're paying attention to what is a human being, you do have to go down to sociality as a very essential feature.
