A categorical imperative crying in the wilderness, a duty which nobody need listen to, or suffer for disregarding, seemed rather a forlorn authority. To save the face of absolute right another world seemed to be required, as in orthodox Christianity, in which it might be duly vindicated and obeyed.
Kant’s scepticism, by which all knowledge of reality was denied us, played conveniently into the hands of this pious requirement. If the whole natural world, which we can learn something about by experience, is merely an idea in our minds, nothing prevents any sort of real but unknown world from lying about us unawares. What could be more plausible and opportune than that the categorical imperative which the human mind, the builder of this visible world, had rejected, should in that other real world be the head stone of the corner?
