Metaphysics (from the Greek): beyond or after physics. The area of human thoughts and convictions that lie beyond the realm of scientific human knowledge and experience and therefore in the realm of beliefs, creeds, intuition, theology or supernatural revelation. Such thoughts or convictions are incapable of scientific proof and frequently, although not always, of disproof.
