 This objection is hard to assess for a number of reasons. One is that there are many different kinds of sophisticated concepts and capacities and accounting for them all is a large task. Another is that, while the objection is posed as an objection to all teleosemantic theories, different versions will address it in different ways. Yet another is that we might allow that it is still early days with respect to the development of teleological (and other) naturalistic theories of mental content. It has really only been since the advent of cognitive science in the middle of the last century and the general acceptance of a broadly physicalist perspective on the mind in the decades that followed that philosophers of mind have devoted much effort to trying to give a naturalistic theory of mental content.
