Dr. Bahnsen summarizes the presuppositional defense of the faith as developed by Dr. Cornelius Van Til. He first sets forth the exegetical and epistemological considerations which require a presuppositional method, and then replies to two of Dr. Van Til’s critics (representing opposing theories of knowledge): Gordon Clark and John W. Montgomery.

The set concludes with a brief analysis of Francis Schaeffer and R. C. Sproul.
