In this essay, my focus is R. G. Collingwood’s historicized moral thinking. For Collingwood, the main categories of practical reason are utility, right and duty; they differ both in kind and in degree and exhibit different levels of rationality. Drawing on Collingwood’s idealist notion of “the scale of forms” and his unique version of historicism, I try to make the point that for Collingwood the consciousness of duty—that is, the highest form of practical reason—is ultimately identical with historical consciousness. In this sense, it seems to me that Collingwood can be seen as a substantial critic of the moral crisis of modern European civilization in terms of naturalism and scientism.
