Greg Bahnsen
Notes
Greg Bahnsen (1948–1995), American Calvinist theologian, Cornelius Van Til's most capable student and the person who turned presuppositionalism into a debating method. His 1985 debate with the atheist Gordon Stein is the canonical performance of the Transcendental Argument and the template for everything the online presuppositionalists do.
