Others who have posted reviews of this book are certainly correct in their assessment -- it's engaging, harrowing, enlightening, etc. HOWEVER, nobody has addressed the actual CAUSE of Schreber's insanity which, of course, is key to the reading of his memoir. The patient in most cases, and certainly in this case, is unable to tell us matter-of-factly what is troubling him. Instead, he tells us of his dreams or his imaginings, or his horrible delusions. It is then the psychiatrist who untangles the web. I can't recommend highly enough, as a companion to Schreber's memoir, the book "Soul Murder: Persecution in the Family," written by the psychiatrist Morton Schatzman. The book is now out of print, but can still be found used. Instead of describing the book,I'll quote from the jacket flap: "Daniel Paul Schreber (1842-1911), an eminent German judge, went mad at the age of 42, recovered, and eight and a half years later, went mad again. It is uncertain if he was ever fully sane, in the ordinary social sense, again. His father, Daniel Gottlieb Moritz Schreber (1808-1861), who supervised his son's upbringing, was a leading German physician and pedagogue, whose studies and writings on child rearing techniques strongly influenced his practices during his life and long after his death. The father thought his age to be morally "soft" and "decayed" owing mainly to laxity in educating and disciplining children at home and school. He proposed to "battle" the "weakness" of his era with an elaborate system aimed at making children obedient and subject to adults. He expected that following his precepts would lead to a better society and "race." The father applied these same basic principals in raising his own children, including Daniel Paul and another son, Daniel Gustav, the elder, who also went mad and committed suicide in his thirties. Psychiatrists consider the case of the former, Daniel Paul, as the classic model of paranoia and schizophrenia, but even Freud and Bleuler (in their analyses of the son's illness) failed to link the strange experiences of Daniel Paul, for which he was thought mad, to his father's totalitarian child-rearing practices. In "Soul Murder," Morton Schatzman does just that -- connects the father's methods with the elements of the son's experience, and vice versa. This is done through a detailed analysis and comparison of Daniel Paul's "Memoirs of My Nervous Illness," a diary written during his second, long confinement, with his father's published and widely read writings on child rearing. The result is a startling and profoundly disturbing study of the nature and origin of mental illness -- a book that calls into question the value of classical models for defining mental illness and suggests the directions that the search for new models might take. As such, the author's findings touch on many domains: education, psychiatry, religion, sociology, politics -- the micro-politics of child-rearing and family life and their relation to the macro-politics of larger human groups." For me, this book shed a great light on "Memoirs of My Nervous Illness." In reading the other reviews, I get the sense that some people have concluded that Daniel (the son) "simply went mad," or "something went wrong," when the truth is that his father was a border-line personality and one sadistic man who inflicted his own brand of insanity on his children. If only we had something to document the father's childhood . . .
