The coupling-constitution fallacy

The coupling-constitution fallacy claims that arguments for extended cognition involve the inference of “x and y constitute z” from “x is coupled to y” and that such inferences are fallacious. We argue that the coupling-constitution fallacy fails in its goal to undermine the hypothesis of extended cognition: appeal to the coupling-constitution fallacy to rule out possible empirical counterexamples to intracranialism is fallacious. We demonstrate that appeals to coupling-constitution worries are problematic by constructing the fallacious argument against the hypothesis of extended cognition. We consider several objections to our argument and find them insufficient to rebut our conclusion.
