Hadot shows how the schools, trends, and ideas of ancient Greek and Roman philosophy strove to transform the individual's mode of perceiving and being in the world. For the ancients, philosophical theory and the philosophical way of life were inseparably linked. Hadot asks us to consider whether and how this connection might be reestablished today.
