Certainly, what Kant calls the transcendental reference, experience and object of experience are in a sense present in both opposed views of the nature of the subjective *a-priori*. In both cases the object must ‘order itself’ according to the rules of the knowing mind or its functions, irrespective of whether the specific function of cognition is based on a systematic construction, synthetization, formation of the object from ‘given’ sensational material or on a methodical selection-process (suppression, abstraction, disregard) imposed on a self-constituting object. For if the order of selection in which the fulness of the world, as it is in ipseity, reaches man (or a particular kind of man, e.g., a type of racial or cultural unity) is so governed that an object of essence *B* is only given when an object of essence *A* has already been given (if, that is to say, *A* has datum-priority over *B* in order of time―not necessarily in direct succession), then if an object *X* is simultaneously of essence *A* and *B*, everything which is true of *A* must necessarily be true of *X*―not vice versa. For example, if spatiality and extensity have strict perceptual priority over all essential properties of matter and corporeality, geometry must be strictly valid for all possible bodies. But the same principle, the applicability of geometry to all bodies without exception, would still hold good if Kant’s doctrine were true―though it denies the very reality of extension and space, and explains the spatial form as merely a subjective aspect of the datum. Thus in both cases the transcendental validity of the so-called *a-priori*, even for the objects of experience, would persist, so that in itself it offers us *no* criterion of choice between one or other *hypothesis*―that which supposes a synthetic addition of the form on the part of the spontaneous mind, or the other, which postulates an ordered selection in conformity with foreknown essences.” ―from_On the Eternal in Man_.
