R. D. Laing

Ronald David Laing (7 October 1927 - 23 August 1989), was a Scottish psychiatrist who wrote extensively on mental illness - in particular, the experience of psychosis. Laing's views on the causes and treatment of serious mental disfunction, greatly influenced by existential philosophy, ran counter to the psychiatric orthodoxy of the day by taking the expressed feelings of the individual patient or client as valid descriptions of lived experience rather than simply as symptoms of some separate or underlying disorder. Often associated with the anti-psychiatry movement, he himself rejected the label as such, as did certain others critical of conventional psychiatry at the time
