This is the proper place to explain the paradox of method in a critique of practical reason, namely, that the concept of good and evil must not be determined before the moral law (of which it seems as if it must be the foundation), but only after it and by means of it.
Hauxe da leku egokia arrazoimen praktikoaren kritika batean metodoaren paradoxa argitzeko, hots, ongiaren eta gaizkiaren adigaiak ezin direla lege moralaren aurretik determinatu (hura itxuraz oinarrian ezarri beharko bailitzateke), baizik eta soilik haren ondoren (hemen gertatu denez) eta haren bitartez.
