But this real constitution, or (as it is apt to be called) essence, being utterly unknown to us, any sound that is put to stand for it must be very uncertain in its application; and it will be impossible to know what things are or ought to be called a HORSE, or ANTIMONY, when those words are put for real essences that we have no ideas of at all.
Baina osaera edo, dei dakiokeen bezala, esentzia erreal hau guztiz ezezagun dugunez, berau ordezkatzeko jartzen den soinu oro ziurtasunik gabea da nahitaez bere aplikazioan, eta ezin izanen dugu jakin zeri deitu behar zaion zaldi edo antimonio, hitz horiek erabat ezezagun ditugun esentzia errealak adierazteko erabiltzen direnean.
