The Divided Self, by Ronald Laing
As mentioned, the neurodiversity movement also draws on antipsychiatry and the C/S/X, including radical strands such as Mad Pride and its appropriation of traditionally derogatory terms such as “psycho,” “crazy,” and “nut.” These movements wish to deconstruct stereotyped and stigmatizing representations in science, medicine, and public culture at large (Rowland 2015). While they developed as “revolts from below” (Crossley 1998), they historically followed the “revolt from above” that began within professional psychiatry with Robert Laing and David Cooper in the United Kingdom, Thomas Szasz in the United States, and Franco Basaglia in Italy. Laing’s The Divided Self was published in 1960, Cooper’s Psychiatry and AntiPsychiatry in 1967, and the first C/S/X, the Mental Patients’ Union, appeared in Britain in 1973.
Please beware that, though it is written Robert in the book by Vidal and Ortega, the author's actual name is Ronald David Laing — oops! There is a TV documentary about him, called Did You Used to Be R.D. Laing?, linked below. Enjoy!
