This chapter explores a significant thesis that emerges in Heidegger’s reading of Kant: the linear, unidirectional form of time that Kant outlines is dependent on another model of time – the human temporality comprising three interlaced temporal capacities. The chapter argues that developing this thesis represents the central philosophical payoff of Heidegger’s Kant interpretation; Heidegger goes to Kant to develop his own account of temporal idealism. Heidegger concurs with Kant that the form of time is relative to the human standpoint, but offers a deeper account of where that form of time comes from – i.e., how it derives from the very structure of the human being. While Being and Time attempts to trace the characteristics of linear time back to the human being’s temporality, Heidegger’s account of time in the Kant interpretation elaborates how temporality produces linear time. Specifically, Heidegger outlines the process of self-affection, in which the interaction between the human being’s three temporal capacities actualizes another model of time by interpreting the time that we ourselves are. This argumentative approach foregrounds a gap between the temporality of the human being and the interpretation of time upon which we arrive, suggesting that time could be otherwise interpreted.

The introduction presents some general reflections on what characterises Heidegger’s fundamental ontology and what makes his thought a particularly promising point of departure for doing social ontology. I first introduce Heidegger’s holistic conceptions of Dasein and being-in-the-world by way of contrast to Cartesian atomism. I then go on to show that Heidegger conceives of intersubjectivity as a triangular relation between self, world, and other rather than a dyadic relation between two independent subjects. My claim is that Heidegger’s social ontology is found directly in his conception of the shared world and that his more well-known accounts of the Anyone and solicitude should be understood within this general framework. I also reflect on the relation between Heidegger’s social ontology and his politics and provide an outline of the book.

Reconstructs Heidegger’s well-known analysis of Dasein as analogous to his interpretation of Kant: I argue that Heidegger also views Dasein as a (pre-)ontological, phenomenological, and hermeneutic way of being. Demonstrating this requires a circular reading of the first book of Being and Time. Following Heidegger's own argumentation leads us from Dasein's usual and predominant understanding of being (6.1), through the structural moments of 'being-in-the-world' that constitute its possibility (6.2), to 'care' as the foundational unity of these conditions (6.3). Once this is established, reading Heidegger's magnum opus backwards shows that Dasein is at its core an ontological way of being due to its concern for the being of beings, enacts this concern in a phenomenological manner through its 'being-in', and is thereby both enabled and hindered by the hermeneutic situation of its everyday understanding (6.4). By distinguishing the argumentative procedure of Being in Time from the resulting picture of our human condition, this chapter provides a more systematic picture of Dasein's existential constitution than Heidegger managed to display.

Explains how Heidegger’s interpretation of Kant and his analysis of Dasein relate to the primary interest of his philosophical enterprise: the retrieval of the question of being. The introduction to Being and Time indicates that these three projects formally presuppose one another because Heidegger weds the ontological task of philosophy to its phenomenological and hermeneutical method (9.1). At the same time, this threefold conception of philosophy – ontology, phenomenology, hermeneutics – establishes a hermeneutic situation that informed Heidegger’s interpretations of Kant and Dasein (9.2). Heidegger admits to the circularity of this philosophical procedure, but defends it by distinguishing between a formal, a philosophical, and a factual ‘starting point’ of the ‘hermeneutical circle’ (9.3). At stake here is the relation between Dasein and philosophy, as well as Heidegger's contested choice to approach the meaning of being via our own existence.

Part III deploys the theories and approaches presented in Parts I and II, along with art historical texts, to develop a new interpretational framework for artworks that make rhythm and matter explicit.
