Abstract
Two-dimensionalism is a formal framework used in formal semantics, epistemology and the philosophy of mind. The technical background dates back to the early seventies, in particular to Krister Segerberg’s paper “Two-Dimensional Modal Logic”. The mathematical tools developed in that tradition can be used to model the relations between two semantical properties of concepts or expressions, which, according to two-dimensionalism, can be conceived to be two kinds of intensions. I shall present the general ideas of two-dimensionalism, and give a brief reconstruction and discussion of one application in the philosophy of mind.
I would like to thank Oliver Beermann, Dieter Birnbacher, Axel Bühler, Anneli Mottweiler, John Perry, Barry Smith, and an anonymous referee for helpful comments on earlier drafts of this paper.

I will concentrate on identity only. Chalmers takes it that physicalism is best understood as a supervenience thesis, and hence argues against this supervenience. I think that physicalism should be formulated as an identity claim. Arguments in favor of my position can be found in [Per101]. For the purpose of the present paper the difference doesn’t matter.
