The text discusses Georges Canguilhem's theory of health and shows the influence of Friedrich Nietzsche on his work and the possible parallels in the concept of health, such as the emphasis on the individuality of the ill person and the transcendence of mere physiological and scientific symptoms when talking about health. The text works primarily with Canguilhem's Writings on Medicine and Knowledge of Life and Nietzsche's The Gay Science and Ecce Homo.
