Knowra Thomism Thomism Thomism is the philosophical and theological tradition based on Thomas Aquinas’s teachings. It integrates Aristotelian philosophy with Christian doctrine, especially in metaphysics, ethics, and theology.
Thomas Aquinas : A medieval Dominican philosopher and theologian whose writings shaped Catholic theology and Western philosophy. His works supply Thomism’s central arguments and principles.
Act and potency : A metaphysical distinction between what is realized and what has the capacity to be realized. Aquinas uses it to explain change without reducing change to mere illusion or creation from nothing.
Albertus Magnus : A thirteenth-century Dominican scholar who studied and taught Aristotelian philosophy and was Thomas Aquinas’s teacher. His teaching helped prepare the intellectual setting in which Aquinas developed his synthesis.
Augustinianism : A Christian intellectual tradition shaped by Augustine, emphasizing divine illumination, grace, and the inward life of the soul. Its emphases differ from Thomism’s systematic use of Aristotelian philosophy.
Thomistic ethics : An ethical framework grounded in Aquinas’s account of human nature, virtue, practical reason, and the natural law. It applies Thomist metaphysics to judgments about action and human flourishing.
Aristotelianism : A philosophical tradition deriving from Aristotle’s works on logic, nature, metaphysics, and ethics. Aquinas adapted Aristotelian concepts to explain Christian doctrine.
Essence and existence : A distinction between what a thing is and the fact that it exists. Thomists treat their composition in creatures as central to dependence on God.
Latin translations of Aristotle : Medieval translations that made Aristotle’s works available to Latin-speaking scholars, often through Arabic or Greek intermediaries. They brought the Aristotelian corpus into the debates Aquinas addressed.
Scotism : The philosophical and theological tradition based on the writings of John Duns Scotus. Its accounts of univocity, individuation, and divine freedom offer influential alternatives to Thomist positions.
Virtue ethics : An approach to ethics that centers on virtues, character, and the cultivation of a flourishing life. Aquinas’s account of moral formation connects Thomism to a major tradition in contemporary ethics.
