The causal argument also has its fair share of problems. The strange notions of reality that Descartes introduces are easy prey to attack. Why claim, for instance, that there is any special kind of reality called "objective reality?" Why assume, for that matter, that reality comes in grades that are so metaphysically loaded? Even more fatal than these legitimate worries, however, is the fact that Descartes' central claim is demonstrably false. We do not all have a clear and distinct innate idea of God as a being of infinite perfection. The only people who have this idea are those who were raised in cultures where the notion of a single and perfect supreme being was prevalent.
