Thomas, Gordon. Journey into Madness: Medical Torture and the Mind Controllers. London: Corgi, 1989. Print.
"What remains for me the most disturbing aspect of my investigation is that even as I write, and later when it is read, there are physicians who continue to participate in torture. Nothing I had researched before could have prepared me for the dark reality of doctors who set out to deliberately destroy minds and bodies they were trained to heal. The realization that physicians are part of a killing machine provokes a special horror."
