A Reconsideration of Aquinas’s Fourth Way

Attitudes towards the fourth way differ from incredulity and embarrassment to seeing it as a profound demonstration of God’s existence. Aside from general treatments on all the five ways, the fourth way has received little by way of direct commentary in comparison to the other better known (and arguably better appreciated) ways. In this article I seek to present Aquinas’s fourth way as a way to God which makes use of his general and more familiar metaphysical reasoning. This serves to give the reading of the fourth way as a profound argument for God’s existence, and also to integrate it with the other four ways given the common metaphysical backdrop.
