In this First Friday Lecture, University of Chicago Graham School Basic Program instructor Clare Pearson examines parts of Immanuel Kant’s Critique of Pure Reason in relation to his Grounding for the Metaphysics of Morals, with attention to how themes from the former bear on the latter. The lecture opens with background on Kant’s intellectual development, including his early Epicurean views on morality, his engagement with Plato, his admiration for Rousseau, and his reading of Hume, whom he credits in the preface to the Critique with prompting a rethinking of his philosophy. Pearson then turns to the central questions of the Critique of Pure Reason, focusing on the possibility and limits of theoretical reason—what we can and cannot know, and why. She discusses Hume’s challenge to claims of universality and necessity and outlines several key elements of Kant’s account of how the mind structures experience, including space and time as forms of intuition, the categories of understanding, and the role of reason in formulating general principles. The lecture goes on to consider implications for the self, including what Kant suggests can be known about our existence beyond appearances, and how this relates to moral philosophy. Pearson also addresses Kant’s discussion of regulative ideals, such as the ideas of the soul, a necessary being, and the world as a whole, which cannot be established through theoretical reason. Drawing on the example of Leonidas at Thermopylae, she explores how Kantian moral action can be understood in situations of uncertainty. The lecture concludes with a discussion of the role of respect in Kant’s ethics and its relation to themes in Plato’s account of the good.
