 A final point about broad aims is that teleological theories of mental content are usually intended as real nature theories. Those who offer real nature theories of intentional mental states think that our everyday ability to recognize the intentional mental states of ourselves and others does not make us experts on the fundamental nature of these intentional mental states, any more than our everyday ability to recognize water makes us experts on the fundamental nature of water. Teleological theories of mental content do not entail that, if Bill thinks that Mavis knows that today is Tuesday, then Bill must, in so thinking, be thinking that certain teleological functions pertain to Mavis’s cognitive system.
