On this standpoint, it makes no difference whether the principles should be regarded as objective, which means here, as externally existing determinations of nature, or as mere maxims of a subjective cognition; what is subjective here is rather the contingent cognition that applies one or the other maxim as occasion demands, indeed, according to whether it deems them fitting for given objects, but for the rest does not ask about the truth of these determinations themselves, whether they both are determinations of the objects or of cognition.
