Abstract

The “Copernican Revolution” in Kant’s philosophy marks a pivotal epistemological turn in the history of Western philosophy. Drawing primarily on Kant’s Critique of Pure Reason, this paper systematically examines the background, content, and significance of this revolution. It first elucidates the inspiration Kant drew from Copernicus’s heliocentric theory, then analyzes how Kant inverted the traditional relation of conformity between objects and concepts, thereby shifting the center of human cognition from the object to the subject and laying the foundation for synthetic a priori judgments. Subsequently, the paper further demonstrates how Kant’s “Copernican Revolution” transcends both rationalism and empiricism, and, by limiting speculative reason and making room for faith, ultimately aims at the reconstruction of a moral metaphysics. Kant’s “Copernican Revolution” not only delimits the legitimate boundaries of rational cognition but also defends the practical realm of human freedom and dignity, exerting a profound influence on subsequent philosophy.
