Throughout this series on Christian philosophy, it has been my argument that Christianity is a system of ideas thought out together. Christianity is not the only system of thought, it is not the only worldview. Marxism, for example, is a systematic attempt to provide a comprehensive worldview. On the other hand, Christianity is unique in that it is God’s revealed system of thought. it is truth itself. Paul’s statement, “Eye has not seen, nor ear heard, not have entered into the heart of man the things which God has prepared for those who love him” (I Corinthians 2:9), is a denial that man can discover truth on his own.
Throughout the course of history, men, brilliant men such as Plato and Aristotle, have argued that man can too discover truth by his own efforts. Secular epistemology – epistemology is logically the first discipline of philosophy, it is the theory of knowledge answering the question “How do you know?” – comes in one of two forms. Rationalism (Plato) tells us that men can know truth from ideas they come up with in their own minds. Empiricism (Aristotle) argues that man can know truth by observing things. Our senses, say the empiricists, furnish us with knowledge. Christianity, on the other hand, argues that truth, all truth, is graciously revealed by God to men, that men do not discover truth on their own, that the so-called wisdom men claim to have found by their own efforts is, in reality, foolishness.
One’s view of metaphysics – metaphysics is the theory of reality – depends upon his epistemology. Since we live in an age in which empirical epistemology is dominant, it is not surprising that people believe that matter, physical stuff, is the ultimate reality. Carl Sagan gave voice to this idea when he wrote, “The cosmos is all that is or was or ever will be.” But as John Robbins wrote in his tract What is Christian Philosophy?, Christian metaphysics, which is based upon a Christian theory of knowledge, speaks in this way, “in God, not matter, we live and move and have our being.” The universe is not eternal, but created Not independent, but upheld by God. Not evolving to perfection, but advancing in its decay.
