The modern origins of presuppositional apologetics are in the work of Dutch theologian Cornelius Van Til, a member of the Orthodox Presbyterian Church, who began to adopt a presuppositional approach to defending the truth of his faith as early as the late 1920s. Van Til personally disliked the term "presuppositional", as he felt it misrepresented his approach to apologetics, which he felt was focused primarily on the preeminence of the Bible as the ultimate criterion for truth, rather than denying or ignoring evidence. He did, however, accept the label reluctantly, given that it was a useful way of distinguishing between those who deny a neutral basis for apologetics and those who do not. His student, Greg Bahnsen, aided in some of the later developments of Van Tillian Presuppositionalism, and the Bahnsen Theological Seminary continues to promote presuppositional apologetics in its curriculum. John Frame, another student of Van Til, also continues to advocate a presuppositional approach, although he is generally more critical of Van Til's thought than Bahnsen was. Bahnsen's protégé, Michael R. Butler, has also been active in advancing the field. Among his contributions is a technical, metalogical study of transcendental arguments in general and the Transcendental argument for the existence of God in particular, which he wrote for Bahnsen's festschrift.
