Despite their aura of self-containment and apparent closure the instit
utions built to confine people diagnosed as 'mentally deficient' or 'f
eebleminded' were closely connected to broader social structures. A re
cent paper presenting involuntary sterilization almost exclusively as
an internal control measure attempts to sever this relationship. Yet t
he encoding of eugenic forces both within and beyond the asylum wall r
einforces the idea that, far from being institutionally disconnected f
rom modern society, the custodial asylum represents one of its most po
werful archetypes.
