““Shorter believes that psychosomatic illnesses (such as leg paralysis at the turn of the twentieth century or multiple personality disorder at the turn of the twenty-first) are examples of the unconscious mind attempting to speak in a language of emotional distress that will be understood in its time. People at a given moment in history in need of expressing their psychological suffering have a limited number of symptoms to choose from—a “symptom pool,” as he calls it. When someone unconsciously latches onto a behavior in the symptom pool, he or she is doing so for a very specific reason: the person is taking troubling emotions and internal conflicts that are often indistinct or frustratingly beyond expression and distilling them into a symptom or behavior that is a culturally recognized signal of suffering.””
