For if one posits the categories in pure understanding, only that deduction can keep one from considering them, with Plato, to be innate and from basing on them extravagant pretensions of theories of the suprasensible theories of which there is no end in sight thus turning theology into a magic lantern of chimeras; or, on the other hand, if one considers the categories to be acquired, only the deduction can keep one from restricting, with Epicurus, each and every use of them, even that for a practical aim, merely to objects and determining bases of the senses.
