On the Law in General is a single chapter of Girolamo Zanchi's Tractatus de Redemptione, part of what has been called an unfinished Protestant "summa" akin to that of Thomas Aquinas. In this selection Zanchi examines the relationship of the natural law to human law, church tradition, custom, divine laws, and the Mosaic law, offering a rigorous analysis of the nature of law in general, constituting a seminal work in early modern political and legal theory.
