Thomas Aquinas: Reconciling Faith and Reason in Thomistic Philosophy

Thomas Aquinas: Faith and Reason

Thomas Aquinas attempts to reconcile the thought of Aristotle with Christianity, defending the uniqueness of each truth.

Thomistic Thought: Faith and Reason

Aquinas establishes a clear distinction between faith and reason, noting they are two different faculties of knowledge, each with its own field of study and methods to arrive at the truth:

• Common Truths: Certain truths can be known through both, such as the existence of God.
• Hierarchy: Faith is above reason, and above faith is divine illumination.
• Non-contradiction: There cannot be any contradiction between faith and reason because truth is unique.

Metaphysics: An Original Synthesis

Aquinas provides an original synthesis of principles and ideas from previous philosophers, especially Aristotle:

Aristotelian Principles

• Doctrine of substance
• Hylomorphism
• Act and potency
• The four causes

Non-Aristotelian Principles

• Essence and Existence: Adds a fundamental structure beyond Aristotle's substance.
• Causality: Interpreted in a Christian way; God is the exemplary cause.
• Participation: The concept that to be caused is to partake in the cause.
• Degrees of Perfection: A hierarchical view of the universe where the more perfect are closer to God.

Anthropology: A Dualistic View

Following Aristotle and Christian tradition, Aquinas presents a dualistic view of man consisting of a body and an immortal soul. The soul is composed of:

• Lower powers: Empirical cognitive functions and appetitive passions.
• Higher powers: Intelligence (reasoning) and the will.

While sensory functions die with the body, the cognitive functions continue.

Theory of Knowledge

Influenced by Aristotle, Aquinas offers an empiricist interpretation of knowledge:

• No innate knowledge: All knowledge is learned and originates from sensory experience.
• Types of knowledge: Man possesses empirical knowledge (singular, particular, contingent) and rational-intellectual knowledge (universal, general, necessary).
• Theory of Abstraction: Explains the transition from empirical to intellectual knowledge through the senses, memory, and the abstraction process of the understanding.
