Eastern religions, like Taoism and Hinduism, have an impersonal “god” (e.g., Brahman or ultimate reality). How then can anyone know that this “god” is impersonal? After all, this “god” cannot communicate anything about itself to man since communication is personal. This is arbitrary, to say the least, and self-refuting.
Agnosticism, which claims that one cannot know if God exists, has no basis for the existence of knowledge and thus is stuck in a catch-22. The agnostic cannot even know if he can or cannot know if knowledge exists. Thus, he cannot even know if he is in a position to determine if God exists or not. (Confusing, isn’t it?) Thus, it is inconsistent and self-contradictory.
...Naturalism, which is a belief that nature (all that is physical) is all that exists, is itself not part of nature—being conceptual and nonphysical. Thus, naturalism stands opposed to naturalism. This is inconsistent and self-refuting."
