The house as a mind.

Palaeoanthropologists and evolutionary psychologists have successfully used the increasing size of the brain during human evolution to infer cognitive and social outcomes. Archaeologists have applied similar reasoning to the development of technology in deep history. This paper goes beyond these approaches by considering the house as a metaphor for the structure of hominin minds. It is argued that the study of the mind in deep history requires, (1) a recognition that mind is distributed between bodies, brains, and the world. The implications are examined through a magnetic resonance imaging (MRI) study (that unwraps the cerebellum and which suggests that folding rather than cortex size may be more important for understanding cognition.; (2) unmasking the ingrained container- habitus that has been used to describe and investigate minds either in the present or deep past. This bias is explored by entering the eccentric house-mind of Sir John Soane (1753-1837) with its many compartments, paintings, and antiquities; and (3) an exploration of alternative embodied metaphors to enable archaeologists to study distributed mind in deep history. The metaphor ARCHITECTURE WITHOUT WALLS is discussed and briefly compared to the evidence for 'houses' in the Middle and Upper Pleistocene. The evidence indicates that hominins have always had complex, distributed minds but only recently in our deep history did we come to think predominantly through and with artificial containers such as houses. Late in human history these constructions became a common-sense habitus that expressed and fashioned our cognitive experience of the world.
