Aquinas' Five Ways

Aquinas' Five Ways are arguments for the existence of God, formulated by Saint Thomas Aquinas in the 13th century. They include: 1. **The Argument from Motion**: Everything in motion was moved by something else; there must be an unmoved mover, which is God. 2. **The Argument from Causation**: Every effect has a cause; there must be a first cause, which is God. 3. **The Argument from Contingency**: Things exist that could not exist; there must be a necessary being that caused them, which is God. 4. **The Argument from Degree**: There are different degrees of goodness; the source of all perfection is God. 5. **The Argument from Design**: The order and purpose in the world imply an intelligent designer, which is God.
