Abstract

Over the years, various critics have accused Kant of a rigorism that is the moral equivalent of fiat iustitia ruat caelum. But this involves a greatly mistaken view of the nature and bearing of his categorical imperative. What Kant does in ethics is to employ a two domain approach that separates a rigoristic realm of theory from a more flexible realm of praxis that is oriented towards the real world of our experience. In the moral sphere demands of the former, theoretical realm are indeed rigoristic, but this rigorism cannot reasonably be extended into the practical realm of action, decision, and advice.
