But whilst our complex ideas of the sorts of substances are so remote from that internal real constitution on which their sensible qualities depend, and are made up of nothing but an imperfect collection of those apparent qualities our senses can discover, there can be few general propositions concerning substances of whose real truth we can be certainly assured; since there are but few simple ideas of whose connexion and necessary co-existence we can have certain and undoubted knowledge.
Baina substantzien espezieez ditugun ideiak haien koalitate sentigarriak menpean dituen osaera errealetik hain urrun dauden bitartean eta ideia horiek gure sentimenek deskubri ditzaketen ageriko koalitate horien bilduma inperfektuak osatzen dituen bitartean, substantziei buruzko proposizio gutxi izan daitezke euren egia erreala guk ziurtasunez baieztatzeko modukoak, ideia bakun gutxiren lotura eta beharrezko koexistentzia ezagut baititzakegu ziurtasunez eta zalantzarik gabe.
