Laing is a psychoanalyst who "is engaged in research on schizophrenia and on the family at Tavistock Institute of Human Relations, London," while his collaborator, Cooper, "is a psychiatrist at Shenley Hospital, Hertfordshire, concerned with research on families and on groups." Both men are strongly impressed by the importance of Sartre's most recent major works: Saint Genet, Search for a Method, and Critique de la Raison Dialectique, which they see as major landmarks in modern intellectual history. Sartre, they say, is.
