Critique of Practical Reason
Works authored by Kant on the topic include the initial publication "The Groundwork of the Metaphysics of Morals" followed by "The Critique of Practical Reason", "The Metaphysics of Morals", "Anthropology from a Pragmatic Point of View", "Religion within the Boundaries of Mere Reason", the latter commentaries developing the intellectual figure's thinking. Within the pages of "Anthropology from a Pragmatic Point of View" in particular, the philosopher articulated a vision of people as by their very essence driven by meaningful ethics. Through the lens of Kant's doctrine, no ironclad divide has existed between morality and the natural world, with empirical analysis of human psychology dovetailing with studies of people's ideals.
