To repeat the whole nature of the world abstractly, universally, and distinctly in concepts, and thus to store up, as it were, a reflected image of it in permanent concepts always at the command of the reason; this and nothing else is philosophy.
Munduaren esentzia osoa abstraktuki, orokorki eta argiro kontzeptutan birsortzea, eta hori horrela kopia errainutu gisa arrazoimenaren adigai iraunkor eta beti prest daudenetan ezartzea: hori da eta ez besterik filosofia.
