This paper aims to focus on the Weberian concept of Weltbild, considered as one of the most important analytic instruments of his sociology. I will argue that Weltbilder have a mainly cognitive function, with a direct practical effect: they are framing devices, that allow men to orient themselves in the world. In this sense, the Weberian concept of Weltbild differs from the notion of Ideology. I will base my argument on two different elements: the peculiar theoretical status of World-images and (...) their relationship with material factors. Unlike ideologies, in fact, Weltbilder do not deal with the distinction true-false: they are conceivable as cultural constructions, the relationship with whom can only take the form of belief. Secondly, they are not simply functional products of material interests: in Weberian analysis, ideal and material factors have a mutual influence, that is not deducible by a rule. (shrink)
