Concise Summary of Augustine on the Existence of God

Overview of Augustine's Argument

Augustine's work in "On the Free Choice of the Will" (OFCW) presents a complex argument regarding the existence of God, focusing on his conception of God and questions surrounding the origin of evil and free will.

Structure of OFCW

  • Book I: Explores that moral evil results from the free choice of will.

  • Book II: Offers an original argument for the existence of God and examines the rationale behind free will.

  • Book III: Discusses divine foreknowledge and the origin of free will.

Key Questions Raised in Book II

  1. How is it evident that God exists?

  2. Do all good things come from God?

  3. Is free will considered a good?

Augustine's Conception of God

  • God embodying pure Being: God is immutable, eternal, simple, supreme, and ontologically independent, having created the universe ex nihilo.

  • The doctrine of the Trinity showcases God's complexity and against Neoplatonism.

Augustine's Original Argument for God's Existence

Augustine presents not just a traditional argument but one deeply influenced by Neoplatonism. He argues:

  • Truth exists above human understanding, reflecting several key points:

    • Shared perceptions of sense objects.

    • Commonality in human reasoning and truths, such as numbers.

  • Summary of Argument:

    1. Truth exists, which is above the human mind.

    2. Either something exists above this truth or not.

    3. If yes, that being is God. If no, then the truth itself is God.

Attributes of God According to Augustine

  • Immutability: change denotes imperfection, thus God is unchangeable.

  • Supremacy: God is the highest good, comprehended through Latin definitions of God.

  • Trinitarian Understanding: Augustine uses metaphors from human cognition to approach the doctrine of the Trinity, presenting concepts of memory, understanding, and will as a triadic structure of divine reality.

Addressing Early Christian Controversies

  • Augustine navigates early misunderstandings of the Trinity, addressing subordinationism and Arianism, emphasizing the need for a consolidated doctrine of God.

This initial exploration sets the authority for Augustine’s arguments on free will, moral evil, and divine existence, creating a significant foundational thought in Medieval Philosophy.
