Book excerpt: Psychoanalysis and Toileting is an accessible book that delineates and interprets the psychological meanings of defecating and urinating in everyday life. Paul Marcus’ work gives the clinician an in-depth view of an activity that every patient and practitioner engage in and shows how not dealing with toileting in its wide range of social and practical contexts leaves out a huge aspect of the patient’s everyday experience. Drawing from psychoanalytic theory and practice, the author discusses such subjects as constipation, diarrhea and irritable bowel syndrome, adult female incontinence, toilet cursing, public toilet graffiti and toilet humor. The book also considers the personal meaning of urinating and defecating as seen in men suffering from an enlarged prostate, in ‘excremental assault’ in the Nazi concentration camps, and in dreaming. Marcus considers not only what is typically negative about these experiences, but what can be seen as positive in terms of growth and development for the ordinary person. The book is illustrated throughout with clinical vignettes and observations taken from the author’s private practice. Psychoanalysis and Toileting will be a key text for psychoanalysts and psychoanalytic psychotherapists in practice and in training. It will also be relevant to other mental health practitioners.
