Now the above-mentioned postulates concern only the physical or metaphysical conditions of the possibility of the summum bonum; in a word, those which lie in the nature of things; not, however, for the sake of an arbitrary speculative purpose, but of a practically necessary end of a pure rational will, which in this case does not choose, but obeys an inexorable command of reason, the foundation of which is objective, in the constitution of things as they must be universally judged by pure reason, and is not based on inclination; for we are in nowise justified in assuming, on account of what we wish on merely subjective grounds, that the means thereto are possible or that its object is real.
Baina aipatutako postulatuek ongi gorenaren ahalgarritasunaren baldintza fisikoekin edo metafisikoekin baino ez dute zer ikusia, hitz batean gauzen izaeran datzaten baldintzekin, baina ez asmo espekulatibo nahierazko baten mesedetan, baizik eta arrazoimen-nahimen huts baten praktikoki beharrezkoa den xede baten mesedetan, nahiz eta horrek hemen ez aukeratu, baizik eta arrazoimenaren agindu ezinbestekoari men egiten dion, bere oinarria objektiboki gauzen eraketan duen aginduari, arrazoimen hutsak orokorki juzgatu behar duen bezala, eta ez da joeran oinarritzen, horrek ez baitu baimenik inolaz ere guk oinarri subjektiboengatik desiratzen dugunaren mesedetan berehala horretarako bitartekoak ahalgarri gisa edo objektu erreal gisa onartzeko.
