Greenberg & Harman on Conceptual Role Semantics

Mark Greenberg and Gilbert Harman, “Conceptual Role Semantics”:http://www.princeton.edu/~harman/Papers/CRS.pdf, draft for The Oxford Handbook of Philosophy of Language, to be edited by Ernest Lepore and Barry Smith. Comments invited.

bq. Conceptual role semantics (CRS) is the view that the most important aspects of the meanings of expressions of a language or other symbol system are determined and explained by the way expressions in that language or system are used in thinking. The theory can be taken to be applicable to language in the ordinary sense, to mental representations, conceived of as part of a “language of thought”, or to certain other sorts of symbol systems. CRS rejects the competing idea that thoughts have intrinsic content that is prior to the use of concepts in thought. According to CRS, meaning and content derive from use, not the other way round.
