Meanings as Species

One kind of meaning is constituted by what we need to grasp about usage to be competent participants in a community’s linguistic practices. This book proposes that this sort of meaning is primarily a matter of common knowledge about the presuppositions speakers make in using their language. It argues we should think of this as a population-level, process-like phenomenon. It’s population-level since what needs to be grasped is determined by a rough equilibrium of assumptions across speakers; it’s process-like since what needs to be grasped is a dynamic property of a practice: the competent speaker needs to track how what’s taken for granted about a community’s words fluctuates as the environment changes what is salient to all. The case for thinking of meaning in this way is a matter of its payoffs in theorizing about language. Thinking of meaning in this way reconciles Quine’s skepticism about an epistemically interesting sort of analyticity with the belief that everyday talk about meaning tracks something real, something about which we can and should theorize. It helps ground a sensible way of thinking about philosophical analysis and the role of our intuitions therein, and helps resolve a number of puzzles about relations between illocution and meaning. It helps ground a way of thinking about our practices of ascribing content to others. And it helps provide an understanding of ‘conceptual engineering’—as an attempt to add or subtract from interpretive common ground but not (necessarily) to shift reference—that makes such engineering look like a sensible, conceivably successful project.
