When Descartes philosophy deals with reality and what is deception, God enters the picture. God, being an all powerful being is considered when the idea of something perfect is thought of. Since every idea must have some relevance to reality, the thought of perfection must have come from somewhere (Ex nihilo nihil fit; nothing comes from nothing). The idea of perfection must have been placed in our minds by a perfect being. Therefore God exists. The proof of God 's existence is explained in different terms because the translation cannot always be correct. The main components of the proof are always present.
In Descartes meditation III, Descartes uses the idea of perfection to prove that God exists. This is one interpretation of Descartes proof of the existence of God.

4) I have an idea of perfection or infinite substance.
5) My idea of perfection is the most objectively real idea that I have.
6) The only possible formal
