God's Existence Summary Now that Descartes has found a piece of certain knowledge—that he exists as a thinking thing—he starts to look around for more of these self- evident truths.
Clear and Distinct Ideas At the outset of the Third Meditation, Descartes tried to use this first truth as the paradigm for his general account of the possibilities for achieving human knowledge.
In the cogito, awareness of myself, of thinking, and of existence are somehow combined in such a way as to result in an intuitive grasp of a truth that cannot be doubted. Perhaps we can find in other cases the same grounds for indubitable truth.
But what is it? The answer lies in Descartes's theory of ideas. Considered formally, as the content of my thinking activity, the ideas involved in the cogito are unusually clear and distinct. III But ideas may also be considered objectively, as the mental representatives of things that really exist.
According to a representative realist like Descartes, then, the connections among our ideas yield truth only when they correspond to the way the world really is. But it is not obvious that our clear and distinct ideas do correspond to the reality of things, since we suppose that there may be an omnipotent deceiver.
In some measure, the reliability of our ideas may depend on the source from which they are derived. Descartes held that there are only three possibilities: III But I don't yet know that there is an outside world, and I can imagine almost anything, so everything depends on whether god exists and deceives me.
God Exists The next step in the pursuit of knowledge, then, is to prove that god does indeed exist. Descartes 's starting point for such a proof is the principle that the cause of any idea must have at least as much reality as the content of the idea itself.
But since my idea of god has an absolutely unlimited content, the cause of this idea must itself be infinite, and only the truly existing god is that. In other words, my idea of god cannot be either adventitious or factitious since I could neither experience god directly nor discover the concept of perfection in myselfso it must be innately provided by god.
III As a backup to this argument, Descartes offered a traditional version of the cosmological argument for god's existence. From the cogito I know that I exist, and since I am not perfect in every way, I cannot have caused myself.
So something else must have caused my existence, and no matter what that something is my parents? The chain of causes must end eventually, and that will be with the ultimate, perfect, self-caused being, or god. As Antoine Arnauld pointed out in an Objection published along with the Meditations themselves, there is a problem with this reasoning.
Since Descartes will use the existence and veracity of god to prove the reliability of clear and distinct ideas in Meditation Four, his use of clear and distinct ideas to prove the existence of god in Meditation Three is an example of circular reasoning.
We must rely on a non-deceiving god only as the guarantor of veridical memorywhen a demonstrative argument involves too many steps to be held in the mind at once. But this response is not entirely convincing. The problem is a significant one, since the proof of god's existence is not only the first attempt to establish the reality of something outside the self but also the foundation for every further attempt to do so.
If this proof fails, then Descartes's hopes for human knowledge are severely curtailed, and I am stuck in solipsismunable to be perfectly certain of anything more than my own existence as a thinking thing.
With this reservation in mind, we'll continue through the Meditations, seeing how Descartes tried to dismantle his own reasons for doubt. Deception and Error The proof of god's existence actually makes the hypothetical doubt of the First Meditation a little worse: I now know that there really is a being powerful enough to deceive me at every turn.
But Descartes argued that since all perfections naturally go together, and since deception is invariably the product of imperfection, it follows that the truly omnipotent being has no reason or motive for deception. God does not deceive, and doubt of the deepest sort may be abandoned forever.
IV It follows that the simple natures and the truths of mathematics are now secure. In fact, Descartes maintained, I can now live in perfect confidence that my intellectual faculties, bestowed on me by a veracious god, are properly designed for the apprehension of truth.Descartes Study Questions study guide by brian_the includes 28 questions covering vocabulary, terms and more.

He expounds on his argument about God’s existence from the discourse. Descartes analyzes his mind so as to know whether there exists anything that would let him make God up. Descartes realizes that he is finite compared to God who is infinite, perfect and all powerful.

Overall, both Berkeley and Descartes studied the existence of God and tried to find proofs based on the ideas and perception, thus on the basis of mind work. Their arguments have rational points, but still finally both of them failed to produce absolutely indisputable arguments for God’s existence.
The existence of God has been a question since the idea of God was conceived. Descartes tries to prove Gods existence, to disprove his Evil demon theory, and to show that there is without a doubt something external to ones own existence.
