Writes Clark, “It is because we are so prone to think that the mental action is all, or nearly all, on the inside, that we have developed sciences and images of the mind that are, in a fundamental sense, inadequate.” We will “begin to see ourselves aright,” he suggests, only when we recognize the role of material things in our thinking—when we correct the errors and omissions of the brainbound perspective, and “put brain, body, and world together again.”
