"The Five Ways" - Thomas Aquinas

Aquinas is trying to prove the existence of God in five ways. In Robinson's book, it talks about the First and Third articles. The First Article considers the question of whether God's existence is self-evident, meaning that the Five Ways are not necessary. The Third Article is the question of whether God exists, using the Five Ways as proof.
In the First Article, Aquinas says that “God exists” is self-evident in itself, but not to us, and thus requires demonstration and says that the knowledge of God is naturally implanted in everyone.
In the Third Article, Aquinas's Five Ways to prove God's existence:
1. The Way of Motion: In the world, something things are in motion.
2. The Way of Causation: The nature of efficient cause.
3. The Way of Contingency: Possibility and necessity
4. The Way of Goodness: The gradation to be found in things.
5. The Way of Design: The governance of the world.

In the recommedned reading, "Cosmological Argument" - Brian Davies, the Cosmological Argument is saying that the existence of the universe is strong evidence for the existence that there is a God who created it.
