Thanks. I didn't remember the Kant connection (I can't seem to get to the end of a paragraph without forgetting the beginning). My definition is a kind of blurry augmentation of Physics & Metaphysics. Scientific or Philosophical aren't perfect synonyms for these but I think they give us a little more of a hint as to what kind of process to employ when thinking about them. I think modern usage of the term dates to Aristotle's books: Physics & Metaphysics. 'Physics' is about nature and feels like a direct ancestor to modern science. 'Metaphysics' is pretty close to what we still call metaphysics. Most people think of these things (logic, ethics, epistemology as science). Physical and metaphysical are the better terms. More accurate. But, I just don't like the associations most people have with them. Physics is impenetrable domain of extreme experts. Metaphysical doesn't have any expectation of rigor and every answer is equally valid. There are other problems like thinking of Metaphysics as completely separate and not impacting on physics like the mind/brain issue you discuss. I think to a modern, rigorous thinker the idea that the mind being a metaphysical concept which is embodies in a brain makes sense. It doesn't imply the kind of dualistic worldview usually associated with spirit and matter.
