We have ground from revelation, and several other reasons, to believe with assurance that there are such creatures: but our senses not being able to discover them, we want the means of knowing their particular existences.
Badugu oinarrirk errebelazioan eta bestelako arrazoi batzuetan, ziurtasunez sinesteko badirela horrelako kreaturak, baina gure sentimenek haiek deskubritzeko gai ez direnez, ez daukagu horien existentzia partikularrak ezagutzeko modurik.
