skepticism. On the empiricist side, Hume thought that all mental content derives from original impressions. Kant shows that we cannot presume that the mind is simply given discrete impressions of the world. By the time the mind can represent even simple impressions from given objects, it has already engaged in extensive conceptual processes that introduce a robust a priori structure into the world of possible experience. Descartes thought that his famous cogito, that is, subjective self-consciousness, is intelligible in complete isolation from any possible object of thought. Kant undermines this claim as well. Self-consciousness involves a synthesis that constitutes general features of objects, so it depends essentially on some relation to objects. One can tease this claim out of Kant’s argument in the deduction, and he makes it explicitly in a short argument that he adds to the second edition of the Critique, called the “Refutation of Idealism.” Here he argues that the mind can only be conscious of itself insofar as it manages to unify the sequence of its own thoughts, experiences, representations, and so on. Unifying a sequence of different states requires that the mind can contrast the flow of the sequence to something persistent and unchanging that is distinct from it. Therefore the fact that we are self-conscious implies awareness of the existence of something permanent outside of us. We can only have a Cartesian cogito if we also have basic background knowledge of objects.

      Kant’s influence on the development of philosophy and psychology throughout the nineteenth and early twentieth century is enormous, and this sketch only scratches the surface of the main ideas from his critical philosophy. But it suffices to highlight several key aspects in which phenomenology from Husserl to Merleau-Ponty is a Kantian enterprise: the idea of constitution, the temporal structure of synthesis, and the idea of subject–object identity.

      Both Heidegger and Merleau-Ponty sharply reject the cognitivism of Kant’s philosophy. They do not think that the basic structures that enable us to experience an objective world are conceptual, or even primarily mental. They do not think of object-constitution in Kantian or Husserlian terms. Nevertheless they, too, argue that a hidden, pre-personal structure makes experience possible and that it is the job of philosophy to uncover and describe this structure. Rather than concepts, they argue that pre-personal conditions of intelligibility consist of our bodily habits and skills, developed and deployed in a specific cultural setting.

      Kant’s analysis of the threefold synthesis has a direct impact on the work of both Husserl and Heidegger. It is the basis for Husserl’s theory of time consciousness. Inspired by his mentor Franz Brentano (who, in turn, is influenced by Kant), Husserl develops an account according to which we are always conscious of temporally thick objects. A present intention is always coupled with conscious retention of the immediate past and a forward-looking “protention.” We discuss this account in Chapter 3. Like Kant, Husserl also uses his analysis of the temporal structure of consciousness to give an account of the nature of the conscious self, analogous to Kant’s analysis of apperception.

      Heidegger writes and lectures extensively on Kant’s analysis of the threefold synthesis (Heidegger 1927/1928, 1929). Since Heidegger rejects Kant’s cognitivism, though, his interpretation forces a substantial transformation onto Kant’s core insight. The synthesis, for Heidegger, is not an activity of the mind in which it brings distinct conscious representations together. Instead it is a pre-cognitive unifying activity of the whole person, in which your purposive abilities reveal things as already mattering and inviting you to act. Like Kant, Heidegger locates the structure of the self in this unifying structure, and like Husserl he thinks the structure is fundamentally temporal. But both the notion of time and the notion of the self undergo a deep transformation. We discuss Heidegger’s account of temporality and the self in Chapter 4.

      Hegel’s system is a breathtaking and daring revision of Kant’s critical philosophy. But Hegel still maintains Kant’s overall focus on consciousness. Absolute knowing, for Hegel, is the province of a conscious, conceptually mediated relation to objects. Even though he recognizes the crucial role of desire, the body, physical work, and the fear of death as constitutive processes in a gradual, historical process of achieving self-consciousness, their contribution to his analysis is always conceptual. Heidegger and Merleau-Ponty, on the other hand, think that the essential connection between subject and object consists of non-conceptual interaction. The subject, they argue, only exists and can only find itself “out there” among the entities it is at grips with in the course of pursuing some purposive way of being.

      a priori – non-empirical. Intuitions, concepts, and cognitions are a priori if we do not derive them from, or justify them on the basis of, sensory experience.

      apperception – Kant’s term for self-consciousness.

      cogito – the “I think” that, according to Descartes, constitutes our identities as thinking things. Kant claims that the “I think” must be able to accompany all our representations.

      cognition – human knowledge about, or experience of objects. Cognizing objects requires the unification of intuitions and concepts.

      intuitions – the given data yielded by our senses. They are spatially and temporally structured, but not yet cognized.

      metaphysics – propositions about the world that are necessarily true and whose truth we can establish without recourse to particular experiences of the world.

      refutation of idealism – Kant’s argument that some external, persisting object distinct from us must exist.

      representation – mental content, such as intuitions, concepts, ideas, or judgments. We cognize objects by representing them in our minds.

      representationalism – the broad philosophical view that objects are intelligible to us only insofar as we have mental representations of them. This view is a commonplace for Kant and eighteenth-century philosophy,
