Clark missed the mark: Andy Clark on intrinsic content and extended cognition

This is a plausible reading of what Clark and Chalmers had in mind at the time, but it is not the radical claim at stake in the extended cognition debate.[1] It is a familiar functionalist view of cognition and the mind that it can be realized in a wide range of distinct material bases. Thus, for many species of functionalism about cognition and the mind, it follows that they can be realized in extracranial substrates.[2] And, in truth, even some non-functionalist views of cognition apparently allow for the possibility that cognition extends into the external world.[3] So, the (logical, conceptual, or nomological) possibility of extended cognition seems to us not the kind of radical view the advocates of this view have often implied. This is not, of course, to assess or pass judgment on the truth of these possibilities; it is only to note that they are not what most agitates people about the hypothesis of extended cognition. Framing the radical extended cognition hypothesis is a more delicate matter than framing the modal extended cognition hypothesis, but something like the following is in the ballpark. The radical extended cognition hypothesis maintains that, in many mundane cases of tool use, human cognitive processes extend into the tools. The principal reason this hypothesis is so delicate is that there remains much room for dispute about what constitutes a “mundane” case of tool use, such as keeping a notebook at hand at all times, versus an exotic case of tool use, such as having a computer memory chip implanted in one’s brain. Clark never in so many words defends the idea that there are actual cases of extended cognition. Rather, his tacit commitment must be inferred from such things as his proposal that the brain is made to use tools, so we should view tools as part of the mind (Cf., Clark, 2005, p. 8ff.).
