IF the villages of the Arab Middle East are perfectly flat and oriented toward maintaining that condition, it may be hypothesized that they will be relatively impermeable to progressive influences, internal or external. If, on the other hand, there are groups which are changing their ways, defying the cake of custom, economizing in number of children, making capital investments, repressing emotional release through immediate consumption,' if, in short, there is anything in the nature of an emerging opportunistic middle class in these villages, its existence can be revealed through studies of the social structure. This paper reports the results of an investigation into social differentiation and stratification in the Southern Beqa'a Valley of Lebanon.2 Of special concern here are the methodological problems of research in underdeveloped non-census areas, as well as discovering the existence of differentiation within the homogeneous appearing peasant population in such societies. approach is entirely classificatory.3 To the casual observer the only stratification apparent is that between a very few large landowners who rarely reside in the villages and the multitude of village-dwelling peasants. Familial and religious homogeneity lend to this appearance. Islamic sanction of inter-cousin marriages and village endogamy 4 among other factors ensure patrilineal solidarity. In this agrarian, non-specialized society there is practically no threat to the primacy of the family in the area of statusconferring by any interest group development or identification. On the other hand, the existence of social differentiation based on a fairly elaborate division of labor in Lebanese villages cannot be denied. Literacy, health conditions, quality of gardens, evidence of housing repairs, degree of seclusion of women, care of sewage disposal, educational participation, patterns of deference and aggressiveness in personal interaction-these are a few of the bases * Expanded version of paper read at the annual meeting of the American Sociological September, 1955.
