P. J. Cornish. "Marriage, Slavery, and Natural Rights in the Political Thought of Aquinas." The Review of Politics 60, no. 3 (1998): 545-62.

Recent scholarship has demonstrated that the language of subjective natural rights can be found in a wide variety of medieval juristic and scholastic texts. This is part of a general trend in the study of political ideas that stresses the continuity between medieval and modern political values. However, many leading scholars of medieval political ideas maintain that no language of subjective natural rights can be found in Aquinas’s political writings, based as they are on a famous objective definition of right (jus) as the object of justice (justitia). Other scholars argue that Aquinas’s notion of subjective rights is peripheral to his political philosophy. The essay argues that Aquinas, while commenting on canon law texts, explicitly posits a subjective natural right to marry, based on the natural equality and natural liberty of all human beings. This can be seen by his claim that a slave may contract marriage, even without the consent of the master. This is one example of an instance in which Aquinas refers to specific legal issues in order to explicate his understanding of liberty and right. For Aquinas there are certain areas of liberty or mastery (dominium) that are exempt from all human authority, and wherein a person has rights to decide how to pursue natural human goods.
