Human understanding

Contemporary thinkers either hold that meanings cannot be mental states, or that they are patterns of brain functions. But patterns of social, or brain, interactions cannot be that which we understand. Wittgenstein had another answer (not the one attributed to him by writers who ignore his work in psychology): understanding, he said, is seeing an item as embodying a type Q, thus constraining what items will be seen as the same. Those who cannot see things under an aspect are meaning-blind.That idea is expanded in this article. Its ontology consists of types only: entities that recur in space, time, and possible worlds. Types (Socrates, Man, Red, On, etc.) overlap; Socrates = Bald at some index and not in another. The logic used is thus that of contingent identity. Now some possible worlds are mentally represented; the entities that occur in them are meanings. But such entities may also recur in the real world. Thus the entities we experience, the phenomena, which serve as our meanings, may be identical in the real world with real things. A correspondence theory of truth is thus developed: a sentence is true iff its meaning constitutes, in a specified way, a real situation.
