Descartes And The Existence Of God

Descartes is concerned with the uncertainty of knowledge. When we see, feel, hear, and touch the things around us, we think that they are real.

In effect, due to its infinite nature, we couldn’t have caused it. Only an infinite being could have caused it. This clear and distinct idea of God, along with the facts of the light of nature, shows us that God exists., On that account, God’s perfection assures us that we are not in a dream, that the world is actually the way we perceive it to
