The Apologetic Implications of Self-Deception
A Conditional Resolution of the Apparent Paradox of Self-Deception
Greg L. Bahnsen · 1978; later Covenant Media digital edition
Ph.D. dissertation, University of Southern California, 1978; later Covenant Media Foundation edition.
Overview
Bahnsen examines the apparent paradox of self-deception: how a person can in some sense know a truth while believing or professing its contrary. He evaluates influential philosophical accounts of belief, intention, motivation, awareness, and other-deception, states seven criteria for an adequate theory, and develops an account suited to the biblical claim that unbelievers know God while suppressing that knowledge. The final application connects the analysis to presuppositional apologetics and moral responsibility.
The dissertation is rigorous, unusually transparent, and broad in philosophical engagement. Its greatest strength is methodological: rival solutions are not dismissed by theological assertion but tested against an explicit adequacy framework. Some psychological literature and analytic debates are now dated, yet the core taxonomy and apologetic application remain highly useful.
