'Stress', 'burnout', 'mental overload': the twentieth and twenty-first centuries have witnessed an unrelenting expansion of the meaning of fatigue. The tentacles of exhaustion insinuated themselves into every aspect of our lives, from the workplace to the home, from our relationships with friends and family to the most intimate aspects of our lives. All around us are the signs of a 'burnout society', a society in which fatigue has become the norm. How did this happen? This pioneering book explores the rich and little-known history of fatigue from the Middle Ages to the present. Vigarello shows that our understanding of fatigue, the words used to describe it and the symptoms and explanations of it, have varied greatly over time, reflecting changing social mores and broader aspects of social and political life. He argues that the increased autonomy of people in Western societies (whether genuine or assumed), the positing of a more individualized self and the ever expanding ideal of independence and freedom have made it ever more difficult for us to withstand anything that constrains or limits us. This painful contradiction causes weariness as well as dissatisfaction. Fatigue spreads and becomes stronger, imperceptibly permeating everything, seeping into ordinary moments and unexpected places. Ranging from the history of war, religion and work to the history of the body, the senses and intimacy, this history of fatigue shows how something that seems permanently centred in our bodies has, over the course of centuries, also been ingrained in our minds, in the end affecting the innermost aspects of the self.
