Do you think that this argument shows that materialism is false, or is there a good way for the materialist to respond to the argument?

Choose ONE of the following topics, and write an essay response.
Choice A: Explain and critically evaluate (including at least one objection) Descartes’ “argument from doubt” in support of dualism. Do you think that this argument shows that dualism is correct? Explain and discuss, supporting your answer with reasons.
Choice B: Discuss Thomas Nagel’s “bat” argument. How is it a problem for materialism? Do you think that this argument shows that materialism is false, or is there a good way for the materialist to respond to the argument? Explain and discuss, supporting your answer with reasons.
Guidelines: Your discussion post should be well written and structured (like a short essay – defend a clear thesis, have more than one paragraph supporting your thesis and explaining the ideas), and be at least 300 words long (and you are encouraged to write something longer for a top grade). Then post replies to at least two of your fellow students, discussing the arguments they have presented (at least one reply should be to a student who wrote on a different topic from yours). Replies should be substantive (more than just “I agree” or “I disagree”), and should advance the conversation.
