“You might want to ask why we should think of minds extending into bodies and artefacts, rather than merely interacting with them. Does it make any difference? One answer is that, in the cases described, brain, body and world are not acting as separate interacting systems, but as a coupled system, tightly meshed by complex feedback relations, and that we need to look at the whole in order to understand how the process unfolds.”
“Language is a particularly powerful means of extension and enhancement, serving, in Clark’s phrase, as scaffolding that allows the biological brain to achieve things it could not do on its own. Linguistic symbols provide new focuses of attention, enabling us to track features of the world we would otherwise have missed, and structured sentences highlight logical and semantic relations, allowing us to develop new, more abstract reasoning procedures.”
