 Kant’s distinction between theoretical and practical reason exemplifies how this move from indicative to subjunctive is attempted—as the categorical imperative first requires acknowledging that the will (the base of the subjunctive) is only free when it is not in violation of the laws potentially knowable by theoretical reason (the indicative). Thus, when Kant says that he wishes to create a rational faith by defining the limits of experience, just as when he says that ‘ought’ implies ‘can’, he is really showing, from Rosenstock-Huessy’s perspective, that the entire metaphysical edifice is derived from a lexical ordering of grammar.
