I've argued before that the Kalam Cosmological Argument is incompatible with libertarian free will, but it requires a few assumptions. First it must be the case that thoughts are not merely events but are things that pop into existence. Second, to say the "agent" is the cause of its thought requires an agent to somehow be distinct from its consciousness, such that it can make decisions prior to consciousness. For example, if an agent causes its thoughts it can't do so consciously, because the cause would be prior to the thought, which is the consciousness. I fail to see how an agent can have any control over such an unconscious experience. I created this meme to illustrate the problem.
