Overview

Defining Thomism

Thomism represents the philosophical and theological tradition stemming from the extensive work and thought of Thomas Aquinas (c. 1225โ€“1274), a Dominican friar, philosopher, and Doctor of the Church. It serves as a central reference point for Catholic philosophy and theology, influencing its doctrines and structure.

Aquinas' Legacy

Aquinas' philosophical contributions are notably found in his commentaries on Aristotle and his disputed questions. Theologically, his monumental work, the Summa Theologica, remains a cornerstone of medieval theology and continues to shape Catholic thought. His emphasis on accepting truth regardless of its source is a defining characteristic.

Foundational Principles

Central to Thomism is the belief in the knowability of the world as it is, aligning with philosophical realism. Aquinas integrated Aristotelian metaphysics and terminology, while also incorporating Neoplatonic principles, particularly the idea of participation in being and goodness. This synthesis forms the bedrock of his comprehensive system.

Metaphysics

Axioms of Being

Aquinas identified the principle of non-contradiction and the principle of causality as fundamental axioms of ontology. He posited that any being not contradicting these laws could theoretically exist, including incorporeal entities. This framework underpins his understanding of reality.

Modes of Predication

Thomism distinguishes three modes of predication: univocal (same meaning), analogical (partially same meaning), and equivocal (different meanings). Analogy is crucial for discussing God, as finite language can only approximate divine attributes. This approach allows for meaningful discourse about the transcendent.

Essence and Existence

A core Thomistic concept is the distinction between essence ("whatness") and existence ("is"). A being is defined as "an essence that exists." Aquinas further categorizes existence into essential (substantial) and accidental. Being itself possesses transcendental properties like oneness, truth, and goodness.

Causality

The Four Causes

Following Aristotle, Aquinas articulated four causes essential for understanding any being: the material cause (what it's made of), the formal cause (its essence or form), the efficient cause (what brings it into being), and the final cause (its purpose or end).

The First Cause

Aquinas argued against an infinite regress of causality, asserting the necessity of a First Cause. This uncaused cause, which continuously sustains existence, is identified as God. The chain of causality cannot be infinite; it must originate from a necessary, self-existent being.

Purpose and End

The final cause, or purpose, is integral to Thomistic thought. All things strive towards a final end, and this inherent purpose defines their goodness. Evil, conversely, is understood not as a positive entity but as a privation or lack of good, a defect in purpose or being.

Goodness

The Nature of Good

In Thomism, "the good" is defined as that which all things strive for. Every entity, by virtue of its existence and function, possesses a degree of goodness. This perspective aligns with the Aristotelian concept of teleology, where everything has an inherent purpose.

Evil as Privation

Echoing Augustine, Aquinas defines evil not as a positive force but as privatio boni โ€“ the absence or lack of good. Evil arises from a defect in being or purpose, rather than being a distinct ontological category. This understanding addresses the problem of evil within a framework of divine goodness.

God as Essential Goodness

As the ultimate end of all creation, God is considered goodness itself. Love, defined as wishing the good of another, finds its ultimate expression in leading others towards God. This theological perspective underscores the divine nature as the source and embodiment of all goodness.

The Divine

The Five Ways

Aquinas presented five rational arguments for God's existence, known as the quinque viae: the argument from motion (Unmoved Mover), from efficient causality (First Cause), from contingency (Necessary Being), from degree (Argument from Degree), and from design (Teleological Argument).

Divine Attributes

God's existence is identical to His essence. He is described as perfect, infinite, omnipotent, omniscient, immutable, eternal, and pure actuality (actus purus). These attributes reflect His transcendent and absolute nature, distinct from all created reality.

Analogical Knowledge

Due to God's infinite nature, human knowledge of Him is necessarily analogical. We can understand aspects of God through His creation (general revelation) and scripture (special revelation), but always in a manner that finite minds can grasp, using figurative language to convey spiritual truths.

Anthropology

Rational Animal

Thomism defines humans as "rational animals," emphasizing both our biological nature and our capacity for reason. This definition highlights the integration of the physical and intellectual aspects of human existence.

The Soul as Form

The soul is understood as the substantial form of living beings. Aquinas distinguishes between vegetative souls (plants), sensitive souls (animals), and intellectual souls (humans), which possess rationality and immortality. The soul animates and informs the body, constituting a unified substance.

Mind and Sensation

Human knowledge originates from sensory experience. The mind processes sensory data through imagination (phantasms) and intellect, abstracting universal concepts. This epistemological foundation underscores the importance of empirical observation in acquiring knowledge.

Ethics

Happiness and Virtue

Happiness, defined as the operation according to perfect virtue, is the ultimate human good. Virtue itself is a stable, good habit that guides actions and reactions. Thomistic ethics emphasizes the cultivation of virtuous character for achieving fulfillment.

Cardinal and Theological Virtues

The cardinal virtuesโ€”prudence, temperance, justice, and fortitudeโ€”are natural and universally applicable. These are complemented by the supernatural theological virtues: faith, hope, and charity, which orient the soul directly towards God.

Moral Action

Determining the morality of an action requires considering both circumstances and intention. Thomism utilizes the principle of double effect, justifying actions with good primary effects even if a negative secondary effect is foreseen, provided the good outweighs the evil and the evil is not the means to the good.

Law

Fourfold Division

Thomism recognizes four interconnected types of law: Eternal Law (Divine Wisdom directing all things), Natural Law (rational participation in Eternal Law), Human Law (made by humans for the common good), and Divine Law (revealed moral imperatives).

Natural Law

Natural law, imprinted by God on the human intellect, guides us towards good and away from evil. It is accessible through reason and provides fundamental moral principles, such as the Golden Rule, reflecting God's eternal order within creation.

Free Will

Providence and Freedom

Aquinas reconciled divine providence with human free will. He argued that God, as the primary cause, moves voluntary causes according to their nature, preserving their freedom. God's causality does not negate human agency but rather enables it.

Grace and Volition

Thomistic thought posits that human actions, particularly morally good ones, require divine grace. While God's grace enables virtuous acts, the precise relationship between divine causality and human volition has been a subject of ongoing discussion within Thomistic schools.

Epistemology

Knowledge from Senses

Adhering to the peripatetic axiom, Aquinas maintained that all human knowledge originates from sensory experience. The intellect abstracts universal concepts from sensory data (phantasms), forming the basis of our understanding of reality.

Correspondence Theory

Thomistic epistemology aligns with the correspondence theory of truth, asserting that truth lies in the conformity of the intellect's judgment to external reality. Knowledge is thus grounded in the objective existence of things.

Impact

Shift in Scholasticism

Aquinas significantly shifted Scholasticism from Neoplatonism towards Aristotelianism. His synthesis profoundly influenced Catholic thought, establishing Thomism as a dominant philosophical framework with enduring global reach.

Catholic Doctrine

The Catholic Church officially recognized Aquinas' teachings, particularly through Pope Leo XIII's encyclical Aeterni Patris, which initiated a revival known as Neothomism. This movement emphasized the systematic application of Thomistic principles to critique modern philosophical trends.

History

Early Development

The initial period of Thomism (c. 1256โ€“1325) saw both vigorous defense and opposition, including condemnations of certain theses. The Dominican Order consistently championed Aquinas' work, ensuring its continuity within their educational institutions.

Revival and Modernity

Following the Council of Trent and later spurred by Pope Leo XIII's Aeterni Patris, Thomism experienced significant revivals. Neothomism sought to apply Aquinas' thought critically to modern philosophy, influencing Catholic intellectual life throughout the 19th and 20th centuries.

Perspectives

Key Thinkers

Influential figures like G.K. Chesterton championed Thomism as a philosophy of common sense. Modern interpretations range from Neo-Scholastic Thomism, emphasizing rigorous systemization, to Existential Thomism, focusing on historical exegesis, and the Cracow Circle's use of modern logic.

Diverse Interpretations

Contemporary Thomism continues to evolve, with scholars exploring diverse interpretations and applications of Aquinas' thought. These include integrating modern logic, emphasizing the act of existence, and examining the compatibility of Thomistic principles with contemporary scientific understanding.
