Reforming Apologetics (Worldview)

Summary of Chapter 5

The main aim of chapter 5 of Reforming Apologetics is to criticize “historic worldview theory” (HWT) and the significant role it has played (according to the author) in the development of Van Tilian apologetics. The adoption of HWT is an obstacle to using “the book of nature” in apologetics, and for that very reason it needs to be challenged.

As Dr. Fesko defines it, HWT is

a very distinct idea that begins with nineteenth-century German idealism and includes the following characteristics: (1) the rejection of a common doctrine of humanity, (2) a single principle from which one deduces a worldview, (3) an exhaustive systematic explanation of reality, and (4) the incommensurability of competing worldviews. These aspects of HWT create an inhospitable environment for the historic Reformed appeal to the book of nature. The increased use of HWT is inversely proportional to the decreased use of the book of nature. (p. 98)

Fesko identifies several specific problems with HWT. First, it is “contrary to the teaching of the Scriptures because it rejects a common doctrine of humanity”; in other words, it rejects the biblical teaching that all people share common notions in virtue of bearing the image of God. Second, HWT claims that “a worldview must present an exhaustive explanation of the world,” but the Bible doesn’t do that. According to the Reformed faith, Scripture “does not address all things” but “gives only principles for life in general” (p. 98). In the hands of Van Tilian apologists, HWT implies that the Bible “exhaustively explains all reality” and “must be the only foundation for all knowledge” (p. 99).

Dr. Fesko proposes to make his case by (1) reviewing the historical origins of HWT, (2) explaining how Van Til’s employment of HWT led to his rejection of common notions, (3) surveying the impact of Van Til’s use of HWT on the Reformed community, (4) making “a brief scriptural case for common notions,” and (5) refuting the claim that the Bible “offers an exhaustive view of the world” (p. 99).
