What qualifies someone as mentally ill? The standard for diagnosis is the Diagnostic and Statistical Manual of Mental Disorders (DSM), which just released a 5th edition in 2013 -- but just how objective is it? This episode of Rationally Speaking features Dr. Jerome Wakefield, psychiatrist, PhD in philosophy, and author of "The Loss of Sadness: How Psychiatry Transformed Normal Sorrow into Depressive Disorder." Julia, Massimo and Jerome talk about the arbitrariness of the DSM and the controversies around the boundaries of various mental disorders, including depression and sexual fetishes.
