Truths belonging to essences of things (that is, to abstract ideas) are eternal; and are to be found out by the contemplation only of those essences: as the existence of things is to be known only from experience.
Gauzen esentziei (hau da, ideia abstraktuei) dagozkien egiak betierekoak dira eta esentzia horien kontenplazioz soilik aurkitu behar dira, gauzen existentzia esperientziaz bakarrik ezagutu behar den bezalaxe.
