Thirty-nine educated middle-class residents of Patna, India, were interview
ed about a vignette describing the behaviour of a seemingly mad man or woma
n. The interview explored their representations of traditional healing meth
ods and of modern psychiatric notions. Besides explanations for mental illn
ess and madness, the interviews also covered the reaction of families and n
eighbours to such phenomena. Respondents thought of different causes depend
ing on the context, ranging from frustrated desires, shock and heredity to
spirit possession. The majority's spontaneous preference for modern psychia
tric treatment often co-exists with a faith in traditional healing. This fa
ith is strengthened by their family's traditional preference. The results a
re discussed as an example of a process of modernization of common sense in
which popularized scientific notions become anchored in the traditional se
tting of social structure and family life. The newly acquired knowledge for
ms a loosely organized social representation confronting a strongly objecti
fied cultural representation of traditional thinking.
