I begin with a diagnosis. Present-day scholarly work on the Scottish Enlightenment is bifurcated: it is either focused on the areas of moral philosophy or of natural philosophy, broadly construed in both cases. The aspiration to combine these inquiries is rare and unsystematic. This paper makes a case for the need and possibility of a perspective that conceives moral and natural inquiry as integrated enterprises in the period. It also suggests that potentially useful interpretive devices can be adopted from the (...) historiography of science and philosophy, as well as science studies. (shrink)
