This dissertation studies how seventeenth-century English occult philosophy and magical practice approached, apprehended, and attempted to affect the emotions. It analyses how these early modern people used magic to map, manipulate, and manage emotionality: how the classical elements and humoural theory were used to build up profiles of temperament and emotional proclivities; how divination was used to diagnose particular passional states, relationships, and processes; how ritual and sorcery was used to provoke and galvanise these imbalances and their consequent effects on body, mind, soul, and personal volition; and how magical objects, regimen, and regulatory practices were deployed to constrain and ameliorate passional imbalances.
