Not only are our concepts of substance, of power, of action, of reality, and others, quite independent of experience, containing nothing of sense appearance, and so apparently applicable to things in themselves (noumena), but, what strengthens this conjecture, they contain a necessity of determination in themselves, which experience never attains.
Ez bakarrik gure kontzeptuak substantzia, indar, ekintza, errealitate etab.enak erabat esperientziatik independente daudelako, eta berebat sentimen-fenomenorik ez daukatelako, eta beraz berbaitango gauzak (noumena) begiztatzen dituztela ematen duelako, baizik eta, uste hori oraindik areago sendotzen duena, beren baitan determinazioaren derrigortasun bat edukitzen dutelako, esperientziak inoiz ere parekorik ez duena.
