The reasons are obvious enough: the prisoners are kept in unnatural, isolated conditions, their every activity is so strictly regulated and supervised that they have no opportunity to develop a sense
of individual responsibility, they are
deprived of any
real opportunity to
learn to live as members
of society, their only companions are other criminals, some
of whom are bound to be quite vicious, their sex life must be unnatural, psychiatric treatment is very limited, if non ‑ existent, and employment is limited and stereotyped.
