Chalmers’ and Clark’s extended mind thesis cited in this article from an architecture and design publication.

Turning to philosophy and robotics gives us a new insight into what might be going on. In 1998, A. Clark and D. Chalmers proposed the “extended mind” concept, where the workings of our mind actually extend beyond the brain and into our surroundings. An interplay takes place between our thoughts and internal memories, and knowledge and information stored outside yet within ready reach. Mobile robots do, in fact, use their environment as their memory — they have no stored internal memory, and thus save enormous computational overhead. Rodney Brooks’ Mars Explorer works in precisely this way. Its ability to navigate its environment comes from an “intelligence” that links internal processors with external information.

This implies that the environment is crucial to the development of our brain: our mind is an integral part of our environment, and if we wish it to engage our intelligence, the environment should embody the same degree of organized complexity as our neurological processes themselves. Two possible connective scenarios are thus strikingly contrasted. 1. In an information-sparse, minimalist environment, our mind stops at the skull’s interior. 2. In a coherently complex environment, our mind can extend into and interact with the visual information stored outside. In the latter case, we are situated in a vastly richer information field that drives our brain’s growth in order to process and interpret this information.
