Rationalism and Irrationalism in Non-Christian Thought (Part 1 of 2)

A powerful tool for apologetics is the awareness that all non-Christian thought can be categorized by the tug-of-war between rationalism and irrationalism.

Non-Christian thought also is characterized by irrationalism. How is this the case? Because inevitably the finite and fallen human mind cannot fully capture all of reality into a man-made system. At the point in which the non-Christian rationalist realizes that they cannot account for everything (i.e. makes sense of everything within his worldview), they engage in what Francis Schaeffer called an “upper story leap.” An “upper story leap” is when someone arbitrarily appeals to something that their worldview cannot makes sense of by simple appeals to “the facts” of their worldview.
