All cultures at all times have had central tenets or values they hold to be fundamentally true and that are so integral to the culture’s beliefs and systems that most people in said culture are not even aware that they are holding these “beliefs that seem to not be beliefs but unchallengable, self-evident common sense” (Keller, Preaching, 125).
Our culture is no different. One such example is our culture’s general acceptance that “we are products of an impersonal universe yet [must] be committed to human rights” (Ibid.). These are not two assumptions that naturally stand side-by-side, yet our Western society has lashed them together with the dual cords of “scientific” and “enlightened” thought.
How do we become aware of such patterns of thought in our own worldview and even begin to evaluate whether or not they are indeed true? The first step is to become aware of them, and an excellent place to begin here is to be an avid student of the past. As C.S. Lewis explains:
…we need intimate knowledge of the past. Not that the past has any magic about it, but because we cannot study the future, and yet need something to set against the present, to remind us that the basic assumptions have been quite different in different periods and that much which seems certain to the uneducated is merely temporary fashion. A man who has lived in many places in not likely to be deceived by the local errors of his native village; the scholar has lived in many times and is therefore in some degree immune from the great cataract of nonsense that pours from the press and the microphone of his own age.
-C.S. Lewis, from “Learning in War-Time”
Study the past, then, because of its value in helping to illuminate the blind spots we have today in the present.
