Kant and the Mind
Kant and the Mind was first published in 1994 by Cambridge University Press: in 1996 a paperback edition appeared. As Brook notes in the preface, Kant and the Mind was written for two audiences. First, cognitive scientists, philosophers of mind, and students of cognition. Second, Kant scholars. The book thus has two parts: the first four chapters provide an overview of Kant's model of the mind for general audiences. The second part, written primarily for Kant scholars, attempts to justify the reading given in the first four chapters. Brook emphasizes in the book that Kant had something to offer contemporary psychology, cognitive science and philosophy of mind, he writes, "I think that the discoveries he made about the mind not only were a contribution in their time, but continue to be important now."[8] Brook attributes the following discoveries to Kant: 1) the mind has the ability to synthesize a single coherent representation of self and the world. 2) The mind has a unity that is necessary to produce representation. 3) The mind's awareness of itself has unique features stemming from the semantic apparatus that it uses to achieve this awareness. He also suggests that three of Kant's insights have been adopted by cognitive science: the transcendental method (inference to the best explanation), that experience requires both concepts and percepts; and his general picture of the mind as a system of concept-using functions for manipulating representations.[9] He explains that Kant distrusted introspection as a means of revealing the structure of the mind, yet also had deep reservations about Cartesian a priori arguments. The theory of mind that Brook finds in Kant is not based on either approach, but instead explores what powers the mind must have in order to have experiences and representations that it has.[10]
Brook distinguishes four kinds of awareness, two of which are also kinds of self-awareness: simple awareness (awareness of an object without being aware of being aware), awareness with recognition, awareness of one's representational states and awareness of oneself as the subject of one's representational states.[11] He divides the latter into empirical self-awareness (being aware of one's own mental states) and apperceptive self-awareness (ASA) (being aware of oneself as the subject of those states).[10] ASA is not awareness of oneself as an object with properties; rather, ASA is a bald reference to oneself as existing as oneself. One need not ascribe to oneself any properties whatsoever. If Brook's reading of Kant is correct, then Kant discovered ASA 200 years before contemporary theories.[12]
In addition to these distinctions, Brook writes that Kant thought the mind is not merely the subject that has representations, but is itself a representation. ("The mind, the self, the understanding, the thing that thinks not only has representations; it is a representation.")[13] Not only is the mind a representation under this reading, but it is what Brook calls a global representation (the result of synthesis of a multitude of representations into a single intentional object).[13] Brook argues that treating the mind as a global representation removes any risk of a homunculus problem (Hogan, 1996), and further argues that this global representation is the representational base for ASA.
Reviewing the book, Stevenson wrote in The Philosophical Quarterly, "I venture the judgement that this will be recognized as one of the most important books ever on Kant."[10] However, Eric Watkins in the Journal of the History of Philosophy raised concerns about the literature Brook cited and the more controversial interpretations: "Brook neglects almost entirely the relevant German scholarship on Kant's theory of mind, in the form of work by G. Prauss, W. Carl, M. Frank, G. Mohr, B. Thole and D. Sturma" (Watkins, 1995, p. 3).[14] Watkins further criticizes Brook's claims that one can be aware of the mind as it is and that the mind is a global representation, since the latter directly conflicts with Kant's view that the noumenal self is immaterial, not a representation.[15]
