Introspection: First-Person Access in Science and Agency

This book is about introspection and its use in scientific theorising about the mind. It deals with two connected questions: What is introspection? Does introspection deliver theoretically valuable information about the mind? There is a long history in philosophy and psychology of using introspection to gather data about the mind. Introspection is often held to constitute our best and only direct access to consciousness and hence to be essential to any investigation of the conscious mind. Equally longstanding and widespread, however, are critical concerns that introspection is highly susceptible to interference, which, together with its privacy, renders it unreliable as a source of data about the mind. A major aim of this book is to provide an understanding of introspection that clarifies its epistemic importance in theorising about the mind. In particular, seemingly overwhelming concerns about the reliability of introspection are transformed into something methodologically more tractable. Central to the approach put forward in the book is the distinction between introspection as inquiry and introspection as mental capacity – between introspective method and introspective access. The first part of the book articulates, defends, and applies a historically motivated, novel framework for the systematic assessment of the potential and limitations of introspective methods. The second part develops a composite pluralism about introspective access, showing how different modes of introspective access fit into the common sense and scientific pictures of our minds. Key to this pluralist account is the explanatory role introspection plays in our agency.
