Imagine a society that subjects people to conditions that make
them terribly unhappy then gives them the drugs to take away
their unhappiness. Science fiction It is already happening to
some extent in our own society. Instead of removing the
conditions that make people depressed modern society gives them
antidepressant drugs. In effect antidepressants are a means of
modifying an individual's internal state in such a way as to
enable him to tolerate social conditions that he would otherwise
find intolerable.
