In a recent essay in CSSH (16:1) Oriol Pi-Sunyer has joined in debate with our article ‘Modernization and Development…’ (CSSH 14:3). The thrust of his critique is that our model of social change in the Western Mediterranean leads us inexorably to lump Sicily and Catalonia together with respect to general social and economic developments since World War II. He argues in terms of modernization theory that Catalans long ago developed industry and have always shown a propensity to organize in corporate groups whenever the central government gives them the opportunity to do so. In short, our model is lacking in ‘time depth and political sensitivity’ (pp. 128–9) since it puts the Catalans in the same class as the Sicilians. We wish here to demonstrate that (1) in our article we discussed the differences between Sicily and Catalonia in much the same way that Pi-Sunyer did in his critique; (2) that, in fact, Sicily and Catalonia have undergone similar processes of social change since World War II, in ways that threaten the historical continuity of these societies, both formed over centuries; and (3) that Pi-Sunyer's misreading of our materials is due to his unfortunate confusion of modernization with development, which is precisely what we tried to get away from in our essay.
