Discussion philosophy

Question:

We have already touched upon Metaphysics in the previous modules. You will find that all the divisions of Philosophy connect and overlap. For this module's discussion, answer the following questions:
1. Does reality exist before we are born and after we die? Does it exist while we are living?
2. Does reality consist of only one nature, two, or multiple? What are they?
3. Does it matter if what we believe seems to work for us, even if it may not ultimately be empirically true?
You must relate everything you say to the material in this module. You may use material from previous modules.
