Wonderland by Steven Johnson
Visible in these perplexed diagnoses is a new way of thinking about the psyche. Diseases of the mind did not have to be rooted in some biological deformity, as the phrenologists had contended; nor was it attributable to some abstract “lesion of the will”; nor was it tied to basic biological realities like menstruation or masturbation. Instead, the root cause of the disorder was to be found somewhere else: in the lived history of social and economic change. Modern life itself could make you sick.
