But yet for all this, the miscalling of any of those ideas, contrary to the usual signification of the words of that language, hinders not but that we may have certain and demonstrative knowledge of their several agreements and disagreements, if we will carefully, as in mathematics, keep to the same precise ideas, and trace THEM in their several relations one to another, without being led away by their names.
Baina hala eta guztiz ere, ideia hauei hizkuntza horretan eman ohi zaien izena barik beste bat emateak ez du galarazten haien adostasun eta desdostasun ezberdinen ezagutza ziur eta frogagarria ("demostrative") edukitzea, baldin matematikan bezala ideia zehatz berei lotzen bagatzaizkie eta elkarrekiko erlazio ezberdinetan jarraitzen badiegu, izenen eraginez bide horretatik irten gabe.
