  Like the Relativist, the Deflater seeks a moderate middle ground between the Demarcater and the Debunker. The Deflater agrees with the Demarcater that there is a real distinction between logical and nonlogical constants, and between formally and materially valid arguments. She rejects the Relativist’s position that logical consequence is a relative notion. But she also rejects the Demarcater’s project of finding precise and illuminating necessary and sufficient conditions for logical constancy. “Logical constant”, she holds, is a “family resemblance” term, so we should not expect to uncover a hidden essence that all logical constants share. As Wittgenstein said about the concept of number: “the strength of the thread does not reside in the fact that some one fibre runs through its whole length, but in the overlapping of many fibres” (Wittgenstein 1958, §67). That does not mean that there is no distinction between logical and nonlogical constants, any more than our inability to give a precise definition of “game” means that there is no difference between games and other activities. Nor does it mean that the distinction does not matter. What it means is that we should not expect a principled criterion for logical constancy that explains why logic has a privileged epistemological or semantic status. (For a nice articulation of this kind of view, see Gómez-Torrente 2002.)
