Abstract:

This paper aims to offer a reconstruction of the First Way (Prima Via) proposed by Thomas Aquinas to demonstrate the existence of God in the Summa Theologiae. The Thomist argument in that work explains, first, what kind of rational discourse can be articulated to talk about God’s existence and essence. After he elaborates on the previous point, Aquinas proposes a series of arguments intended to resolve the question of the existence of a divine being and his attributes In what concerns this present text, we will focus on the first way proposed there in favour of the thesis “God exists” and we will also talk about the discursive context in which this proof appears. Thomas refers to it as the first and clearest proof of them all.

Key words:

God, causality, metaphysics, theology, Thomas Aquinas.
