Patricia Kitcher

Kant's discussion of the relations between cognition and self-consciousness lie at the heart of the Critique of Pure Reason, in the celebrated transcendental deduction. Although this section of Kant's masterpiece is widely believed to contain important insights into cognition and self-consciousness, it has long been viewed as unusually obscure. Many philosophers have tried to avoid the transcendental psychology that Kant employed. By contrast, Patricia Kitcher follows Kant's careful delineation of the necessary conditions for knowledge and his intricate argument that knowledge requires self-consciousness. She argues that far from being an exercise in armchair psychology, the thesis that thinkers must be aware of the connections among their mental states offers an astute analysis of the requirements of rational thought.The book opens by situating Kant's theories in the then contemporary debates about "apperception," personal identity and the relations between object cognition and self-consciousness. After laying out Kant's argument that the distinctive kind of knowledge that humans have requires a unified self- consciousness, Kitcher considers the implications of his theory for current problems in the philosophy of mind. If Kant is right that rational cognition requires acts of thought that are at least implicitly conscious, then theories of consciousness face a second "hard problem" beyond the familiar difficulties with the qualities of sensations. How is conscious reasoning to be understood? Kitcher shows that current accounts of the self-ascription of belief have great trouble in explaining the case where subjects know their reasons for the belief. She presents a "new" Kantian approach to handling this problem. In this way, the book reveals Kant as a thinker of great relevance to contemporary philosophy, one whose allegedly obscure achievements provide solutions to problems that are still with us

Although both Kant and Wittgenstein made claims about the “unknowability” of cognitive subjects, the current practice of assimilating their positions is mistaken. I argue that Allison’s attempt to understand the Kantian self through the early Wittgenstein and McDowell’s linking of Kant and the later Wittgenstein distort rather than illuminate. Against McDowell, I argue further that the Critique’s analysis of the necessary conditions for cognition produces an account of the sources of epistemic nonnativity that is importantly different from McDowell’s own account in terms of a ‘second nature’ created through ‘Bildung’. Finally, I argue that Kant’s epistemic analyses also lead to a model of the cognitive self that answers two contemporary questions: why should we refer to selves at all? in what dies the unity of a subject of thought consist?

One of the most widely accepted contemporary constraints on theories of self-knowledge is that they must account for the very different ways in which cognitive subjects know their own minds and the ways in which they know other minds. Through the influence of Peter Strawson, Kant is often taken to be an original source for this view. I argue that Kant is quite explicit in holding the opposite position. In a little discussed passage in the Paralogisms chapter, he argues that cognitive subjects have no way of understanding the minds of others except by using their own minds as a model for others.

Although I begin with a brief look at the idea that as a faculty of mind, apperception must be grounded in some power of the soul, my focus is on claims about the alleged noumenal import of some of Kant’s particular theses about the faculty of apperception: it is inexplicable, immaterial, and can provide evidence that humans are members of the intelligible world. I argue that when the claim of inexplicability is placed in the context of Kant’s standards for transcendental psychological explanation, it has no noumenal implications. Similarly, when understood in the context of his views about scientific explanations, Kant’s claim that the faculty of apperception cannot be understood in materialist terms has no important metaphysical payoff. The case of freedom is different, because for a long time, Kant believed that he could establish the freedom required for morality by appealing to the freedom required for thought. In the end, however, he abandoned this hoped for noumenal implication of the faculty of apperception.

1. What is the Problem of Personal Identity?Locke posed the problem of personal identity in one brief question, “What makes the same person?” This formulation is deceptively simple. My aim is to offer a new interpretation of the problem and to suggest a method for finding a solution.Investigations of personal identity are usually cast in terms of finding the criterion for personal identity. Yet talk of criteria is ambiguous. In one sense of the term, the criterion of personal identity would be special evidence for personal identity. According to the second usage, the criterion of personal identity would be that state of affairs for which evidence for personal identity is evidence. We will not be concerned with the first construal. On that reading, the problem of personal identity would be an epistemological issue. But the basic question concerning personal identity, “What is one person?” does not appear to be an epistemological question.
