- What did Augustine mean by his claim that 'faith seeks understanding'?
Show answer
That reason and rational investigation are proper tools for the believer to deepen and explain their faith, though faith itself comes first.
- How did Augustine argue for God's existence from eternal truths?
Show answer
He observed that mathematical and logical truths exist eternally and unchangingly; these cannot reside in temporal minds, so they must exist in an eternal mind, which is God.
- What is Augustine's 'problem of evil' and his proposed solution?
Show answer
If God is omnipotent and all-good, why does evil exist? Augustine answered that evil is the absence or privation of good, not a positive substance, and that free will is necessary for genuine goodness.
- What role does grace play in Augustine's theology?
Show answer
Grace is God's freely given gift that enables human beings to turn toward God and achieve salvation; it works with or against human free will depending on God's predestining purpose.
- How did Augustine reconcile his Neoplatonic philosophical training with Christian theology?
Show answer
He adopted Neoplatonic ideas of a transcendent, non-material ultimate reality but reinterpreted them through Christian doctrine, seeing the Neoplatonic One as compatible with the Christian God.
- What are the Five Ways in Aquinas's theology?
Show answer
Five arguments for God's existence: from unmoved motion, causality, contingency, degrees of being, and purposive order in nature.
- Explain Aquinas's First Way: the argument from unmoved motion.
Show answer
Everything in motion is moved by something else; tracing back this chain cannot go infinitely, so there must be a first unmoved mover, which is God.
- Explain Aquinas's Second Way: the argument from causality.
Show answer
Everything has an efficient cause; an infinite regress of causes is impossible, so there must be a first cause that causes itself or is uncaused, which is God.
- Explain Aquinas's Third Way: the argument from contingency.
Show answer
Some things exist and some do not; what exists need not exist (contingent things). Not all things can be contingent; there must be a necessary being on which contingent beings depend, which is God.
- Explain Aquinas's Fourth Way: the argument from degrees of being.
Show answer
Things have properties in greater or lesser degrees; there must be a maximum standard of perfection that other things approach, and this maximum is God.
- Explain Aquinas's Fifth Way: the argument from design.
Show answer
Natural things show purposive order despite lacking knowledge; an unintelligent agent cannot direct things to an end without a directing intelligence, so God must exist as the universal director.
- What is Aquinas's distinction between essence and existence?
Show answer
Essence is what a thing is; existence is that it is. In all creatures, essence and existence are distinct (a creature's nature does not guarantee it exists), but in God they are identical.
- How did Aquinas use the concepts of act and potentiality?
Show answer
Act is actuality or fulfillment; potentiality is the capacity to become something. Everything that passes from potentiality to act is moved by something in act; ultimately this traces to God as pure act.
- What is natural law in Aquinas's philosophy?
Show answer
Natural law is the rational creature's participation in eternal law; it is knowable by reason and inclines us toward good and away from evil, and it forms the basis for human and divine law.
- How did Aquinas reconcile Aristotelian philosophy with Christian theology?
Show answer
He adopted Aristotle's metaphysics, logic, and natural philosophy but subordinated them to Christian revelation, showing that reason rightly used and faith are compatible, not contradictory.
