Existence of God

How does Saint Augustine use the concept of "Truth" to prove God's existence?

Augustine argues that since the human mind is fallible but recognizes eternal, immutable truths (like math), there must be a superior source for these truths, which is God.

What is the "Inner Sense" according to Augustine?

It is a "private" reason within the mind that judges the information provided by the "public" senses.

What is the core definition of God in Saint Anselm’s Ontological Argument?

God is defined as "that than which nothing greater can be thought".

According to Anselm, why is existence in reality superior to existence only in the mind?

If the greatest possible being existed only in the mind, we could think of a greater being who also exists in reality; therefore, God must exist in reality to meet the definition.

What is Thomas Aquinas's "First Way" (Motion)?

Since everything in motion is moved by something else, there must be a "First Mover" that was not moved by anything else, which is God.

How does Aquinas's "Fifth Way" (Design) argue for God?

It observes that non-intelligent things in nature act toward a purpose, suggesting they are directed by an intelligent designer, similar to an arrow being guided by an archer.

What is William Paley’s "Watchmaker Analogy"?

Just as the complexity of a watch implies a watchmaker, the far greater complexity of the universe and biological organs (like the eye) implies an intelligent Creator.

According to Gottfried Wilhelm Leibniz, why do we live in "the best of all possible worlds"?

Because God is all-good and all-powerful, He must have chosen the most perfect version of the universe from an infinite number of possibilities.

How does Leibniz explain the existence of evil?

Evil is either a necessary component of a greater good or a result of the inherent limitations of created beings.

What is David Hume’s critique of the machine analogy used by Paley?

Hume argues the universe is not enough like a man-made machine to justify the conclusion that it has a similar conscious designer.

According to Hume, what does the presence of suffering suggest about a "Designer"?

He highlights suffering and disorder as evidence that a designer, if one exists, is likely not all-good or all-powerful.
