This book offers a fundamentally new account of the arguments and concepts which define Heidegger's early philosophy, and locates them in relation to both contemporary analytic philosophy and the history of philosophy. Drawing on recent work in the philosophy of mind and on Heidegger's lectures on Plato and Kant, Sacha Golob argues against existing treatments of Heidegger on intentionality and suggests that Heidegger endorses a unique position with respect to conceptual and representational content; he also examines the implications of this for Heidegger's views on truth, realism and 'being'. He goes on to explore Heidegger's work on the underlying issue of normativity, and focuses on his theory of freedom, arguing that it is freedom that links the existential concerns of Being and Time to concepts such as reason, perfection and obligation. His book offers a distinctive new perspective for students of Heidegger and the history of twentieth-century philosophy.

Between 1927 and 1936, Martin Heidegger devoted almost one thousand pages of close textual commentary to the philosophy of Immanuel Kant. This article aims to shed new light on the relationship between Kant and Heidegger by providing a fresh analysis of two central texts: Heidegger’s 1927/8 lecture course Phenomenological Interpretation of Kant’s Critique of Pure Reason and his 1929 monograph Kant and the Problem of Metaphysics. I argue that to make sense of Heidegger’s reading of Kant, one must resolve two questions. First, how does Heidegger’s Kant understand the concept of the transcendental? Second, what role does the concept of a horizon play in Heidegger’s reconstruction of the Critique? I answer the first question by drawing on Cassam’s model of a self-directed transcendental argument, and the second by examining the relationship between Kant’s doctrine that ‘pure, general logic’ abstracts from all semantic content and Hume’s attack on metaphysics. I close by sketching the implications of my results for Heidegger’s own thought. Ultimately, I conclude that Heidegger’s commentary on the Critical system is defined, above all, by a single issue: the nature of the ‘form’ of intentionality.

Martin Heidegger closes his Winter Semester 1927–28 lectures by claiming that Kant’s Critique of Pure Reason, read through the lens of Edmund Husserl’s phenomenology, confirmed the accuracy of his philosophical path culminating in Being and Time. A notable interpretation of Heidegger’s debt to Kant, advanced by William Blattner, presents Heidegger as a temporal idealist. I argue that attention to Husserl’s adaptation of Kant’s critical philosophy shows that both Husserl and Heidegger are realists. I make my case by tracing a unified philosophical problematic through three puzzling passages: the Schematism chapter of the first Critique, Husserl’s thought experiment of the destruction of the world in Ideas, and the passage in Being and Time that motivates Blattner’s idealist reading. Husserl and Heidegger give accounts, derived from Kant, of how the consciousness of time makes it possible for objects to be perceived as enduring unities, as well as ‘genealogies of logic’ that show how a priori knowledge, including ontology, is possible. These accounts are idealistic only in the sense that they concern the ideal or essential features of intentionality in virtue of which it puts us in touch with things as they are independently of the contributions of any mind of any type.

Drawing inspiration from a well-attested historical tradition, I propose an account of cognition according to which knowledge is not only prior to belief; it is also, and crucially, not a kind of belief. Believing, in turn, is not some sort of botched knowing, but a mental state fundamentally different from knowing, with its own distinctive and complementary role in our cognitive life. I conclude that the main battle-line in the history of epistemology is drawn between the affirmation of a natural mental state in which there is a contact between ‘mind’ and ‘reality’ and the rejection of such a natural mental state. For the former position, there is a mental state which is different in kind from belief, and which is constituted by the presence of the object of cognition to the cognitive subject, with no gap between them. For the latter position, all our cognition is belief, and the question becomes how and when belief is permissible.

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.
