Heidegger has a reputation for reading himself into the philosophers he interprets, and his interpretation of Kant has therefore had little uptake in anglophone Kant scholarship. In this book, Morganna Lambeth provides a new account of Heidegger's method of interpreting Kant, arguing that it is more promising than is typically recognized. On her account, Heidegger thinks that Kant's greatest insights are located in moments of tension, where Kant struggles to articulate something new about his subject-matter. The role of the interpreter, then, is to disentangle competing strands of argument, and to determine which strand is most compelling. Lambeth traces Heidegger's interpretive method across his reading of Kant's Critique of Pure Reason and situates Heidegger's reconstruction of Kant's best line of argument against other post-Kantian readings. She finally shows how Heidegger's deep engagement with Kant sheds light on Heidegger's own philosophical views.
