Rene Descarte's Two Arguments for God's existence

Rene Descarte the father of rationalism ,who said ,"I think, therefore I exist ", gave an argument for the existence of God from the idea of God.

1. God is a inifinitely perfect being
2. We are finite beings
3. All around us ,everything is finite
4. Finite minds cannot originate the idea of a Infinitely perfect being.
5. Therefore the idea of an infintely perfect being should have been given to us by that same infinitely perfect being - who is none other than God.

 "The argument relies on the Scholastic principle that there must be as much reality in the cause in as in the effect. So any ideas of perfection require perfect causes of them. Therefore God, the perfect cause, must exist."

Descarte in his mediatations part 1 and 2 started with skepticism and argues his way out of skepticism in meditations 3 through 5 and gives two arguments for God's existence. The second one goes this way.

1. If God is the most perfect being.
2. And the most perfect being lacks nothing (including existence)
3.Then God necessarily exists

“We can no more think of God without existence than we can think of a mountain without a valley,” Descartes
