Abstract

As a model for explaining the inwardness of mental life, a computer in the cortex is no improvement on an immaterial mind trapped wherever Descartes or Newton originally located it. For both models distract our attention from certain crucial differences between inwardness and interiority - that is, from certain crucial respects in which these two inherited ways of thinking about the inner mind diverge from one another. Clearly, interiority is an inescapable feature of our brains and of all the physiological processes that go on in the central nervous system. There is no doubt at all that those processes are permanently located inside our bodies. So, if our mental lives were, properly speaking, trapped within our brains, they must be trapped there from birth. In this view, our minds must indeed operate permanently à huis clos: like prisoners who are born, live, and die in permanent deadlock. Yet the inwardness of mental life, as we know it and speak of it in everyday experience, is not like that at all. The things that mark so many of our thoughts, wishes, and feelings as inner or inward are not permanent, inescapable, lifelong characteristics. On the contrary, inwardness is in many respects an acquired feature of our experience, a product, in part, of cultural history but in part also of individual development. So understood, our mental lives are not essentially inner lives. Rather, they become inner because we make them so. And we do develop inner lives, in this direct, experiential sense, because we have reasons for doing so.
