ABSTRACT
Ethological concepts of territory are related to ethnic and other social groupings MacLean’s theory of the “triune brain” is used as a metaphor to define two imperfectly integrated psychological environments, one sensual and territorial, the other abstract and symbolic. Those with the narrowest “conceptual worlds” will be most dependent on geographical boundaries; thus it is the poorest and least educated members of a society who will be most likely to seek security in physical territory and least likely to be able to obtain it. A hierarchy of private/public spaces is proposed as a model for community design.
