In recent decades ideological battles have raged over how the history of psychiatry should be interpreted. Should the emergence of psychiatry in the late 18th century be seen as the triumph of the Enlightenment, ushering in a rational approach to mental illness and overturning the primitive and often barbaric ideas of previous eras? Or should the rise of psychiatry be seen in a more sinister light? Does it represent the extension of the state into the lives of its citizens, controlling and policing the disaffected and discontented? Are psychiatrists benign humanitarians or agents of oppression? Should the historical narrative be one of progress, as psychiatry steadily extends its knowledge of mental illness and develops more and more effective therapy? Or is the reverse true: has the advent of psychiatry been a calamity for the mad?
