In the past, when people had psychological problems, neuroscientists would often wrongly jump to the conclusion that something in the persons past was to blame. Nowadays, scientists know more than ever about the growing field of neuroscience. According to recent statistics, over 90 percent of the neuroscientists who ever lived are living now, and more has been accomplished in the field during the past twenty years than the past two hundred. Until recently, the brain could only be studied under extreme situations of illness when symptoms readily appeared. The public lacked interest in matters of the mind, which made neuroscience a difficult field to research.
The legacy of René Descartes' notorious dualism of mind and body extends far beyond academia into everyday thinking: "These athletes are prepared both mentally and physically," and "There's nothing wrong with your body--it's all in your mind." Even among those of us who have battled Descartes' vision, there has been a powerful tendency to treat the mind (that is to say, the brain) as the body's boss, the pilot of the ship.
