debated then librarian D.G. Hart in a student-organized discussion of the regulative principle of worship. Multiperspectival epistemology Frame has elaborated a Christian epistemology in his 1987 work The Doctrine of the Knowledge of God. In this work, he develops what he calls triperspectivalism or multiperspectivalism which says that in every act of knowing, the knower is in constant contact with three things (or "perspectives") – the knowing subject himself, the object of knowledge, and the standard or criteria by which knowledge is attained. He argues that each perspective is interrelated to the others in such a fashion that, in knowing one of these, one actually knows the other two, also. His student and collaborator Vern Poythress has further developed this idea with respect to science and theology. Reformed theologian Meredith Kline wrote a critique of this view, explaining that Poythress and Frame had used multiperspectivalism in ways that had led to what he considered incorrect conclusions in regards to the relation of Kline's position and Greg L. Bahnsen's on covenant theology (more specifically theonomy). Presuppositions As a former student of Van Til, Frame is supporter of the presuppositionalist school of Christian apologetics. He defines a presupposition as follows: Rationalism and irrationalism in non-Christian thought Frame, developing the thought of his mentor Cornelius Van Til, has asserted in both his Apologetics to the Glory of God and his Cornelius Van Til: An Analysis of His Thought, that all non-Christian thought can be categorized as the ebb and flow of rationalism and irrationalism. Rationalism In this context Frame defines rationalism as any attempt to establish the finite human mind as the ultimate standard of truth and falsity. This establishing of the autonomous intellect occurs within the context of rejecting God's revelation of himself in both nature and the Bible; a rationalist, in this sense, states that the human mind is able to fully and exhaustively explain reality. Yet, when Frame speaks of "exhaustive explanations" he does not mean these systems seek omniscience; rather, he means that the history of non-Christian thought (though, admittedly, his focus is Western philosophy) is the history of various attempts to construct systems that account for everything (a distinctive metaphysic, epistemology and value theory). According to Frame, examples of attempts to explain reality are found in Plato and Aristotle's form/matter dualism; the debate between the nominalists and the realists over the status of universals and particulars, and the
