“I suggest that grammar reflects thinking, and thinking conditions grammar. We can only think in the way our language-structures permit us to think. And I note that neuroscientist Michael Gazzaniga (2002) has this to say: “The right hemispheres of split-brain patients… consistently falter on grammatical tasks, such as changing verb tenses, constructing plurals, and indicating possessives.” The right hemisphere struggles with verb tenses. It is the hemisphere of the gods. Whatever deficits the right hemisphere has reflect the deficits of the voices of the gods. Confused grammar, as a transitional reality, means confused voices.”
