A Theological and Philosophical Analysis of The Divided Mind: Contending Descartes

This paper undertakes a theological and philosophical examination of The Divided Mind: Contending Descartes by S. C. Sayles, situating it within the Reformed tradition and the wider contest between revelation and autonomy inaugurated by René Descartes. It argues that Descartes’ Cogito ergo sum initiated the modern fragmentation of consciousness by grounding certainty in self-reference rather than in divine revelation. Sayles’ Logos-centred refutation re-establishes the dependence of thought upon the eternal Word, exposing how the Cartesian method, while analytically brilliant, produced an epistemology of exile. The study proceeds through an analysis of Descartes’ major doctrines—his turn to the self, the dualism of mind and body, the rule of clarity and distinctness, and his circular appeal to God—and contrasts each with the Calvinist vision of knowledge as covenantal participation in the Logos. Drawing upon Augustine, Calvin, Van Til, and Schaeffer, it concludes that Sayles’ work restores unity where modernity has sown division: truth is not deduced from the Cogito but revealed in the Logos. ________________________________________
