What does reality encompass? Is reality exclusively physical? Or does reality include nonphysical--mental, and perhaps 'abstract'--aspects? What is it to be physical or mental, or to be an abstract entity? What are the elements of being, reality's raw materials? How is the manifest image we inherit from our culture and refine in the special sciences related to the scientific image as we have it in fundamental physics? Can physics be understood as providing a 'theory of everything', or do the various sciences make up a hierarchy corresponding to autonomous levels of reality?
