Pierre Hadot

Pierre Hadot (1922–2010) was a French philosopher and historian of philosophy who profoundly reshaped modern interpretations of ancient thought. A leading specialist of Stoicism, Neoplatonism, and early Christianity, he argued that ancient philosophy was not primarily a system of abstract theories but a way of life, grounded in spiritual exercises aimed at transforming perception, judgment, and one’s entire mode of being. In influential works such as Philosophy as a Way of Life and The Inner Citadel, devoted to Marcus Aurelius, Hadot highlights the practical, ethical, and existential dimensions of ancient philosophy, challenging purely academic or theoretical readings.
