Document Summary
How do we know what we know: epistemology. Last time we looked at how the question of justifying what we knew came up in examining arguments for the existence of god. Plantinga denied that we need to justify a belief in god. Descartes thought he could only justify knowledge of the existence of the external world by first proving god"s existence. Only if we know that god created us, and that he isn"t a deceiver, can we infer that our clear and distinct ideas are true. ^this argument depend son a version of the ontological argument to anselm, which. He proves (to his satisfaction) that we can"t be cause of an idea that has more objective reality than we do. Argues that 1 feature of the idea of god is that it contains all perfections. Since existence is a perfection, it is part of the very idea of god that he exists.
