" Everything economic science posits as given, that is, the range of dispositions of the economic agent which ground the illusion of the ahistorical universality of the categories and concepts employed by that science, is, in fact, the paradoxical product of a long collective history, endlessly reproduced in individual histories, which can be fully accounted for only by historical analysis: it is because history has inscribed these concomitantly in social and cognitive structures, practical patterns of thinking, perception and action, that it has conferred the appearance of natural, universal self-evidence on the institutions economics claims to theorize ahistorically; it has done this by, among other things, the amnesia of genesis that is encouraged, in this field as in others, by the immediate accord between the ‘subjective’ and the ‘objective’, between dispositions and positions, between anticipations (or hopes) and opportunities. Against the ahistorical vision of economics, we must, then, reconstitute, on the one hand, the genesis of the economic dispositions of economic agents and, especially, of their tastes, needs, propensities or aptitudes (for calculation, saving or work itself) and, on the other, the genesis of the economic field itself, that is to say, we must trace the history of the process of differentiation and autonomization which leads to the constitution of this specific game: the economic field as a cosmos obeying its own laws and thereby conferring a (limited) validity on the radical autonomization which pure theory effects by constituting the economic sphere as a separate world. It was only very gradually that the sphere of commodity exchange separated itself out from the other fields of existence and its specific nomos asserted itself – the nomos expressed in the tautology ‘business is business’; that economic transactions ceased to be conceived on the model of domestic exchanges, and hence as governed by social or family obligations (‘there’s no sentiment in business’); and that the calculation of individual gain, and hence economic interest, won out as the dominant, if not indeed exclusive, principle of business against the collectively imposed and controlled repression of calculating inclinations associated with the domestic economy.
