For this co-existence can be no further known than it is perceived; and it cannot be perceived but either in particular subjects, by the observation of our senses, or, in general, by the necessary connexion of the ideas themselves.
Izan ere, koexistentzia, hautematen den heinean baino ezin ezagut daiteke, eta ezin daiteke hauteman honelaxe izan ezik, alegia, subjektu partikularretan gure sentimenek ohartematez eta subjektu orokorretan ideien euren beharrezko loturaz.
