This chapter is based on my research into the phenomenology of space and time in schizophrenia, at the time when I worked in the Cassel Hospital, Richmond, England. It was in 1959 that I was given the opportunity of working as a senior medical officer in a hospital for neurotic and borderline patients. The colleagues who introduced me to this hospital were Donald W. Winnicott and Malcolm Pines, my consultant, who put me in touch with the medical director, Thomas Main; all of these practitioners knew of my work with autistic children and, in particular, with adult schizophrenic patients, and they allowed me to undertake the treatment of some borderline psychotic inmates.
