Aquinas' Five Ways: Proving the Existence of God
The Second Way: The Argument from Efficient Causes
In the world of sense, there is an order of efficient causes.
- No thing can be an efficient cause of itself, as it would be prior to itself, which is impossible.
- One cannot proceed indefinitely in the series of efficient causes. If you remove the cause, the effect disappears. In the order of efficient causes, the absence of the first cause would mean the absence of the middle and the last causes.
- If we were to carry the series of causes to infinity, there would be no first efficient cause, no ultimate effect, and no intermediate causes.
- Therefore, it is necessary to admit a first efficient cause: Et hoc dicimus Deum (and this being is God).
