  1. 1. The Measure Of Multitude

    Population in Medieval Thought

    A study of how medieval Europeans conceptualized population—how many people there should be and why—tracing debates among theologians, canon lawyers, physicians, and civic writers about marriage, sex, fertility, celibacy, contraception, and heresy. Drawing on pastoral manuals, scholastic treatises, and civic records, it shows how ideas about the value and risks of the “multitude” shaped moral teaching, social policy, and responses to scarcity, war, and epidemic from the High Middle Ages into the later medieval period.
