There are criteria of ineffability whereby, even if the concept of ineffability can never serve to modify truth, it can sometimes (non-trivially) serve to modify other things, specifically understanding. This allows for a reappraisal of the dispute between those who adopt a traditional reading of Wittgenstein’s T mctatus and those who adopt the new reading recently championed by Diamond, Conant, and others. By maintaining that what the nonsense in the T mctatus is supposed to convey is ineffable understanding, rather than ineffable truth, we can do considerable justice to each of these readings. We can also do considerable justice to the Tractatus.
