Sellars was as original a mind as C.S. Peirce, and it has taken almost as long for the importance of his ideas to be appreciated. Once this collection appears in print, we shall see articles about Sellars popping up all over the journals, just as articles about Peirce began popping up after Hartshorne and Weiss had finished their editorial work. The editors of the collection have made very judicious choices about what to republish. They have arranged the essays in an illuminating sequence so as to make clear that the heart of Sellars's thought is what Brandom calls his "inferentialist" conception of meaning.
Inferentialism was shadowed forth darkly in Wittgenstein's Philosophical Investigations, but Sellars was the first to make it explicit and to grasp its full implications. It represents a radical break with the representationalist way of thinking of mental and linguistic items that has been dominant in Western philosophy since Descartes. The essays in this volume, if read in sequence, gradually unfold to the reader the implications of this non-Cartesian outlook.
As this collection goes along, the inferentialist position sketched in the first two essays is restated in various contexts so that, by the time the concluding papers on Kant are reached, the reader has been given a tour d'horizon not only of the central topics of philosophy of mind and language, but much of the history of philosophy as well.
If analytic philosophers were to come to accept inferentialism, they would have to rethink almost every topic that they have discussed, from intentionality to meaning-change to indeterminacy of reference to mind-body identity to Kant's transcendental ego. There would be a seachange in philosophy far more profound than that caused by Quine's "Two Dogmas." This book, for the first time, gives them the opportunity to study the case for bringing about this change, as that case was presented by the philosopher who first realized inferentialism's full implications. I very much hope that it will be published quickly, since I believe that its appearance will have an important influence on the course of philosophical thought.
