On the Theories on Usury

"On the Theories on Usury" by John Batteridge Pearson, published in 1876, examines the historical and theological perspectives on usury—the practice of charging interest on loans—during the period 1100-1400. Pearson explores how ecclesiastical and secular authorities in Europe adopted or enforced various theories on usury, comparing them with the provisions of Mosaic Law. The book provides insights into the moral, legal, and economic implications of usury in medieval society.
