Since the matter of the practical law, i.e., an object of the maxim, can never be given otherwise than empirically, and the free will is independent on empirical conditions (that is, conditions belonging to the world of sense) and yet is determinable, consequently a free will must find its principle of determination in the law, and yet independently of the matter of the law.
Lege praktikoaren materia, hau da, maximaren objektu bat, enpirikoki baino ezin izan dezakegunez, baina nahimen askeak baldintza enpirikoetatik beregain izanik (hau da, sentsuen munduan kokatu gabe) hala ere determinagarria izan behar duenez, orduan nahimen askeak determinazio-oinarri bat topatu behar du legean legearen materiatik beregainki.
