Fred Dretske

(1932 - 2013)

Materialist explanations of cause and effect tend to embrace epiphenomenalism. Those who try to avoid epiphenomenalism tend to deny either the extrinsicness of meaning or the intrinsicness of causality. I argue that to deny one or the other is equally implausible. Rather, I prefer a different strategy: accept both premises, but deny that epiphenomenalism is necessarily the conclusion. This strategy is available because the premises do not imply the conclusion without the help of an additional premise—namely, that behavior explained by reasons is caused by the reasons that explain it—and this premise is false.

By examining the general conditions in which a structure could come to represent another state of affairs, it is argued that beliefs, a special class of representations, have their contents limited by the sort of information the system in which they occur can pick up and process. If a system — measuring instrument, animal or human being — cannot process information to the effect that something is Q, it cannot represent something as Q. From this it follows (for simple, ostensively acquired concepts at least) that if an organism has the concept Q, if it can believe that things are Q, then it is the kind of organism that has the information-processing capabilities for knowing that something is Q.

This collection of essays by eminent philosopher Fred Dretske brings together work on the theory of knowledge and philosophy of mind spanning thirty years. The two areas combine to lay the groundwork for a naturalistic philosophy of mind. The fifteen essays focus on perception, knowledge, and consciousness. Together, they show the interconnectedness of Dretske's work in epistemology and his more contemporary ideas on philosophy of mind, shedding light on the links which can be made between the two. The first section of the book argues the point that knowledge consists of beliefs with the right objective connection to facts; two essays discuss this conception of knowledge's implications for naturalism. The next section articulates a view of perception, attempting to distinguish conceptual states from phenomenal states. A naturalized philosophy of mind, and thus a naturalized epistemology, is articulated in the third section. This collection will be a valuable resource for a wide range of philosophers and their students, and will also be of interest to cognitive scientists, psychologists, and philosophers of biology.
