Psychoanalytic process, as Eugene Mahon envisions it, is an odyssey through the mind of each of his analysands, the many children and adults he has treated over the forty years of his analytic practice. The painted guinea pigs of the title refer to three-year old children mourning their school pet. "Who painted him?" a child asked when a replacement pet of a slightly different colour arrived in the school a few days after the death of the original pet, as if the dead can return from the grave after a paint job. This book is full of arresting images like this as the author explores many of the most basic, fundamental concepts of psychoanalysis such as repression, insight, transference, play, child analysis, working through, dreams within dreams, jokes, puns, parapraxes, as well as the uncanny in dreams, screen memories, symptom, character and Freud's discovery of the Oedipus complex. This book is a highly original, creative psychoanalytic odyssey, a most intriguing psychological voyage you will not want to disembark from.
