Now, in nature, as it actually is an object of experience, the free will is not of itself determined to maxims which could of themselves be the foundation of a natural system of universal laws, or which could even be adapted to a system so constituted; on the contrary, its maxims are private inclinations which constitute, indeed, a natural whole in conformity with pathological (physical) laws, but could not form part of a system of nature, which would only be possible through our will acting in accordance with pure practical laws.
Baina natura errealean, esperientziaren objektu denez, nahimen askea ez da bere kabuz adosten euren kabuz lege orokorren araberako natura bat oinarri dezaketen halako maximekin, edo haien arabera antolatuta legokeen natura batekin; aitzitik, joera pribatuak dira, lege patologikoen (fisikoen) arabera naturaren osotasun bat osatzen dutenak, baina ez gure nahimen soilak lege praktiko hutsen arabera ahalbide lezakeen natura.
