Nevertheless, the Christian principle of morality itself is not theological (so as to be heteronomy), but is autonomy of pure practical reason, since it does not make the knowledge of God and His will the foundation of these laws, but only of the attainment of the summum bonum, on condition of following these laws, and it does not even place the proper spring of this obedience in the desired results, but solely in the conception of duty, as that of which the faithful observance alone constitutes the worthiness to obtain those happy consequences.
Hori alde batera utziz, moralaren printzipio kristaua ez da teologikoa (eta, beraz, heteronomia), baizik eta berez da arrazoimen praktiko hutsaren autonomia, zeren horrek Jainkoaren eta horren nahimenaren ezagutza ez baitu lege horren oinarri bihurtzen, baizik eta soilik ongi gorenaren lorpenaren oinarri hura betetzearen baldintzapean, eta lehena betetzearen benetako bultzagaia ez du ezartzen haren ondorio desiragarrietan, baizik eta betebeharraren errepresentazioan besterik ez, horren atxikimendu leialean baitatza zoriona lortzeko duintasuna.
