amphiboly

We must first resort to transcendental reflection, in order to determine for which cognitive faculty they are to be objects, whether for pure understanding or for sensibility. In the absence of such reflection, the use of these concepts is very unsafe, giving birth to alleged synthetic principles, which the critical reason cannot recognise, and which are based on nothing better than a transcendental amphiboly, that is, a confounding of an object of pure understanding with appearance.
