Open Letters to Iain McGilchrist—First Letter: On Iain McGilchrist’s Implicit Physiological Confirmation of Kantian Stereoperspectival Epistemology

This book argues that modern science has not refuted Kantian epistemology but has, rather, implicitly confirmed it. Its central thesis is that rationality is intrinsically perspectival, that the distinction between analytic and synthetic modes of thought reflects a deeper epistemological structure, and that Iain McGilchrist’s theory of hemispheric asymmetry provides an unexpected physiological analogue to transcendental philosophy. Building upon a new interpretative framework termed Stereoperspectival Epistemology, the study seeks to establish a dialogue between Kantian transcendental philosophy, contemporary neuroscience, cybernetics, philosophy of science, and the epistemological challenges raised by modern physics. From this perspective, the Kantian distinction between sensibility and understanding is interpreted not merely as a historical doctrine, but as the expression of a fundamental dual structure underlying human cognition. Particular attention is given to the possibility that developments in neuroscience may illuminate, from a physiological standpoint, questions traditionally addressed within transcendental philosophy. The work therefore explores whether Kant’s theory of knowledge can be understood not only as a philosophical account of cognition, but also as an implicit description of the perspectival architecture through which human beings relate to reality. This volume forms part of a broader philosophical project devoted to the reconstruction and extension of the Kantian critical paradigm in the light of contemporary science. It develops ideas first outlined in Preliminaries for a Pure Epistemological Interpretation of the Antinomy of Pure Reason and serves as a bridge toward a number of related works currently in preparation.
