metaphysics is the foundation of philosophy. without an explanation or an interpretation of the world around us, we would be helpless to deal with reality. we could not feed ourselves, or act to preserve our lives. the degree to which our metaphysical worldview is correct is the degree to which we are able to comprehend the world, and act accordingly. without this firm foundation, all knowledge becomes suspect. any flaw in our view of reality will make it more difficult to live.
