" If ensuring the survival of the body proper is what the brain first evolved for, then, when minded brains first appeared, they began by minding the body. And to ensure body survival as effectively as possible, nature, I suggest, stumbled on a highly effective solution: representing the outside world in terms of the modifications it causes in the body proper, that is, representing the environment by modifying the primordial representations of the body proper whenever an interaction between organism and environment takes place.
