Thomas Szasz speaks (Part 2 of 2)

In 1961 maverick psychiatrist and libertarian Professor Thomas Szasz published his controversial and influential epic, The Myth of Mental Illness. Half a century later he maintains we live in a therapeutic state—a 'pharmacracy'—and that psychiatry is a 'pseudoscientific racket'. On the eve of his 89th birthday he joins Natasha Mitchell in conversation. Next week, psychiatrists respond.
