Book Review: “Theology’s Epistemological Dilemma: How Karl Barth and Alvin Plantinga Provide a Unified Response” by Kevin Diller

ted-dillerKevin Diller’s Theology’s Epistemological Dilemma: How Karl Barth and Alvin Plantinga Provide a Unified Response is a work that seeks to offer a unified approach from Karl Barth and Alvin Plantinga to a major difficulty in Christian doctrine: reconciling the necessity of having theological knowledge with the notion that our cognitive capacities are somehow faulty due to sin. But the book is much more than that, for throughout the book Diller gives major, applicable insight into the thought of both Plantinga and Barth.

Diller first goes deeper into the epistemological problem, then analyzes Barth’s view of revelation and his theological epistemology, and wraps up the first part of the book with a deep look at Plantinga’s concept of warrant and how it may impact the question of theological epistemology. He puts forward a consistent interpretation that allows for a unified perspective of Barth’s and Plantinga’s thought. The second part focuses on this unified perspective and puts it forward in analysis of natural theology, human knowledge of God, and Scripture.

Such a brief summary of contents does not do justice to the broad scale of the book, which touches upon many different topics of importance, while always remaining centered on the question of knowledge in theology. Diller has thoughtfully brought forth key aspects of the thoughts of both Barth and Plantinga in such a way as to demand reflection from both philosophers and theologians.

Some of the most interesting insights come from Diller’s integration of Barth’s concept of revelation with Plantinga’s concept of warrant. By focusing on God as self-revealing and self-attesting (Barth), believers are able to maintain warrant in their knowledge of theology (Plantinga).

Another area of profound interest is the way that both Barth and Plantinga approach natural theology–they largely argue that it cannot succeed in its end goal–to demonstrate the existence of God. Barth’s thought reflects this because God will necessarily be hidden from unaided human reason, while Plantinga argues that the arguments of natural theology are part of but do not ground warrant for belief in God. This latter section has much to reflect upon for one who, like me, thinks natural theology can be largely successful.

Theology’s Epistemological Dilemma is a superb, worthwhile read for anyone with interest in the questions of how we may have knowledge within the worldview of Christianity. I highly commend it to my readers.

  1. I’m reading this book now. It’s been helpful, especially since I have only a passing knowledge of Plantinga’s work.

    • Yeah it’s pretty fascinating. What have you found particularly enlightening?

      • The overall thrust of Plantinga’s epistemology, for one. I hadn’t realized he was a critical realist until I picked up his _Faith and Rationality_ a few weeks ago. That alone makes him more endearing, since I could only think of a few other notable thinkers that would fit that description.
