76 THEORIES OF ETHNICITY FREDRIK BARTH n prevents us from understanding the phenomenon of ethnic groups and their place in human society and culture. This is because it begs all the critieal questions: while purporting to give an ídeal type model of a recurring empirical form, it implies a preconceived view of what are the significant factors in the genesis, structure, and function of such groups. Most critiealJy, it allows us to assume that boundary maintenance is unproblematieal and follows from the isolation whieh the itemized characteristies imply: racial difference, cultural difference, social separation and language barriers, spontaneous and organized enmity. This also limits the range of factors that we use to explain cultural diversity: we are led to imagine each group developing its cultural and social form in relative isolation, mainly in response to local ecologie factors, through a history of adaptation by invention and selective borrowing. This history has produced a world of separate peoples, each with their culture and each organized in a society whieh can legitimately be isolated for description as an island to itself However, what is the unit who se continuity in tirne is depícted in such studies? Paradoxically, it must include cultures in the past which would clearly be excluded in the present because of differences in form-differences of precisely the kind that are diagnostie in synchronie differentiation of ethnic units. The interconnection between 'ethnic group' and 'culrure' is certainly not clarified through this confusion. 2. The overt culrural forms whieh can be iternized as traits exhibit the effects of ecology. By this I do not mean to refer to the fact that they reflect a history of adaptation to environment; in a more immediate way they also reflect the external circumstances to whieh actors must accommodate thernselves. The same group of people, with unchanged values and ideas, would surely pursue different pattems of life and instirutionalize different forms of behaviour when faced with the different opportunities offered in different environments? Likewise, we must expect to find that one ethnic group, spread over a territory with varying ecologie circumstances, will exhibit regional diversities of overt institutionalized behaviour whieh do not reflect differences in cultural orientation. How should they then be classified if overt institutional forms are diagnostie? A case in point is the distributions and diversity of Pathan local social systems. By basie Pathan values, a Southern Pathan from the homogeneous, lineage-organized mountain areas, can only find the behaviour of Pathans in Swat so different from, and reprehensible in terms of, their own values that they declare their northern brothers 'no longer Pathan'. Indeed, by 'objectíve' criteria, their overt panem of organization seems much closer to that of Panjabis. But I found it possible, by explaining the circumstances in the north, to make Southern Pathans agree that these were indeed Pathans too, and grudgingly to admit that under those circumstances they might indeed themselves act in the same way. It is thus inadequate to regard overt institutional forms as constituting the cultural features whieh at any time distinguish an ethnie group-these overt forms are determined by ecology as well as by transrnitted culture. Nor can it be claimed that every such diversification within a group represents a first step in the direction of subdivision and multiplication of units. We have well-known documented cases of one ethnic group, also at a relatively simple level of economie organization, occupying several different ~co).ogic niehes and yet retaining basic cultu~al and.ethníc unity over long pm~s (cf., e.g., inland and coastal Chuckchee'" ar reíndeer, river, and coast L.S3). ln one of the following essays, 810m (pp. 74 ff.) argues c~ntly on this point with reference to centrál Norwegian mountain farmers.He shows how their participation and self-evaluation in terms of generál Norwegian values secures them continued membership in the larger ethnic group. despite the highly characteristic and deviant pattems of aetivity whieh the loeal eeology imposes on thern. To analyse such cases, we need a viewpoint that does not eonfuse the effects of ecologie circumstanees on behaviour with those of Ethnic groups a.s culture-bearing units Rather than diseussing the adequacy of this version of culture history for other than pelagie islands, let us look at some of the logieal flaws in the viewpoint. Among the characteristics listed above, the sharing of a common culture is generally given centra I importance. In my view, much can be gained by regarding this very important feature as an implication or result, rather than a prim ary and definitional characteristic cf ethnic group organization. Ifone ehooses to regard the eulture-bearing aspect of ethnic groups as their primary characteristie, this has far-reaehing implications. One is led 'to identify and distinguish ethnic groups by the morphologieal eharaeteristies of the cultures of which they are the bearers. This entails a prejudged viewpoint both on (I) the nature of continuity in time of such units, and (2) the locus of the facrors which determine the form of the units. I. Given the emphasis on the culture-bearing aspect, the classification of persons and local groups as members of an ethnic group must depend on their exhibiting the particular traits of the culture. This is something that can be judged objectively by the ethnographic observer, in the culture-area tradition, regardless of the categories and prejudices of the actors. Differences between groups become differences in trait inventories; the attention is drawn to the analysis of culrures, not of ethnic organization. The dynamie relationship between groups wil1then be depicted in acculturation studies of the kind that have been attracting decreasing interest in anthropology, though their theoretieal inadequacies have never been seriously discussed. Since the historical provenance of any assemblage of culture traits is diverse, the viewpoint also gives scope for an 'ethnohístory' whieh chronicles cultural accretion and change, and seeks to explain why certain iterns were borrowed. ~ .1 '1
