Abstract
This essay is a reappraisal of Pierre Hadot's concept of spiritual exercises in response to recent criticisms of his work. The author argues that contrary to the claims of his critics, Hadot articulates a compelling argument that spiritual exercises that employ imaginative, rhetorical, and cognitive techniques are both necessary for and successful at producing a subject in which reason is integrated into human character. Such exercises are critical for overcoming the effects of habit, as a result of which everyday conduct resists rational control, and Hadot provides a nuanced account of how particular practices affect different aspects of emotion, behavior, and thought. The concept of spiritual exercises remains a viable component of theoretical frameworks for the study of religious ethics, though the author concludes that Hadot's position on habit and its role in ethical practice requires further investigation.
