The Quinque viæ (Latin “Five Ways”) (sometimes called “five proofs”) are five logical arguments regarding the existence of God summarized by the 13th-century Catholic philosopher and theologian St.
Thomas Aquinas in his book Summa Theologica.
What is Aquinas 5th proof for the existence of God?
Aquinas’s fifth and final way to demonstrate God’s existence is an argument from final causes, or ends, in nature (see teleology). Again, he drew upon Aristotle, who held that each thing has its own natural purpose or end.
Which argument did Aquinas not give for the existence of God?
Aristotle argued that the planetary position, which causes the seasons to change, requires an unmoved mover to maintain the order of things. Aquinas’ argument was based on this very premise that without God the heaven and earth would not exist. This implies that any event in the universe is the result of some cause.
What is Descartes proof for the existence of God?
In the same context, Descartes also characterizes the ontological argument as a proof from the “essence” or “nature” of God, arguing that necessary existence cannot be separated from the essence of a supremely perfect being without contradiction.
How did St Anselm prove the existence of God?
The first ontological argument in the Western Christian tradition was proposed by Anselm of Canterbury in his 1078 work Proslogion. Anselm defined God as “a being than which no greater can be conceived”, and argued that this being must exist in the mind, even in the mind of the person who denies the existence of God.
