It covers the treatment of the social sciences under a system of natural law.

Scholars such as Albertus Magnus and Thomas Aquinas interpreted and systematized Aristotle's works in accordance with Catholic theology.

During this time Thomas Aquinas began to study under Albertus.

Albert devoted the last tractatus of De Bono to a theory of justice and natural law.

The Summa Theologiae or Summa Theologica, often referred to simply as the Summa, is the best-known work of Thomas Aquinas (1225–1274), a scholastic theologian and Doctor of the Church.

An author of more than 60 books, he helped to revive Thomas Aquinas for modern times, and was influential in the development and drafting of the Universal Declaration of Human Rights.

The concept of positive law is distinct from "natural law", which comprises inherent rights, conferred not by act of legislation but by "God, nature, or reason."

Thomas Aquinas conflated man-made law (lex humana) and positive law (lex posita or ius positivum).

Among the Scholastics who relied on the classical concept of reason for the development of their doctrines, none were more influential than Saint Thomas Aquinas, who put this concept at the heart of his Natural Law.

Scholastic theologians and philosophers such as the Dominican priest Thomas Aquinas studied and taught at these studia.

Positive ecclesiastical laws, based directly or indirectly upon immutable divine law or natural law, derive formal authority in the case of universal laws from promulgation by the supreme legislator—the Supreme Pontiff—who possesses the totality of legislative, executive and judicial power in his person, while particular laws derive formal authority from promulgation by a legislator inferior to the supreme legislator, whether an ordinary or a delegated legislator.

Prudence was considered by the ancient Greeks and later on by Christian philosophers, most notably Thomas Aquinas, as the cause, measure and form of all virtues.

The Christian understanding of the world includes the existence of God, the natural law and moral implications of human actions.

Medieval Christianity assumed the existence of three kinds of laws: divine law, natural law, and man-made law.

In Thomas Aquinas's Treatise on Law, divine law comes only from revelation or scripture, hence biblical law, and is necessary for human salvation.
