Social scientists of all kinds have been engaged in these sorts of anal yses for at least a century, overtly or covertly When I add covertly, I mean that many social scientists would not define their activities as be ing so immediately tied to the exercise of public rationality. They might define it rather as the pursuit of more perfect knowledge in the abstract. But even when they do this, they know that the knowledge that they produce is being used by others to help achieve the more perfect society. And they are aware that the economic underpinnings of their scientific research are conditioned on their ability to show social benefi t from the work, at least in some longer run. The same Enlightenment assumptions, however, can lead us in a dif ferent, even opposite, direction. The presumed rationality of the social world, just like the presumed rationality of the physical world, implies that lawlike propositions may be formulated that describe it fully and that such propositions hold true across time and space. That is to say, it implies the possibility of universals that can be stated exactly and ele gantly and concludes that the object of our scientific activity is precisely to formulate and test the validity of such universals. This is of course nothing but the adaptation of Newtonian science to the study of so cial realities. And it is therefore no accident that, already in the early nineteenth century, some authors used the label of “social physics” to describe such activity.
