 So it seems to me that Prichard imposes on Kant a view that he neither held nor needed to hold (but see the extended discussion of Kant (153–9), which ends ‘Plainly he had not fully thought the position out.’). Prichard would have done better to concentrate on the difference between Kant’s account of how it comes about that an action is a duty and his own minimal account. Kant’s explanation would start from the fact that the maxim of the action can be willed as a universal law. Prichard would, I think, say that there is no possibility of, or need for, any such explanation. This is just one more instance of the quietism that characterizes intuitionism as opposed to constructivism.
