It seems therefore that, to be certain this proposition is universally true, we must either make a particular demonstration for every particular triangle, which is impossible, or once for all demonstrate it of the ABSTRACT IDEA OF A TRIANGLE, in which all the particulars do indifferently partake and by which they are all equally represented.
Badirudi, hala ere, proposizio hau unibertsalki egiazkoa dela ziur egoteko, honako bata edo bestea egin behar dugula, hots, triangelu unibertsal bakoitzeko demostrazio partikular bat egin, ezinezko dena, edo "triangeluaren ideia abstraktuarekiko" demostratu behin betiko, triangelu partikular guzti-guztiak baitira ideia honetan partaide eta beronek ordezkatuak era berdinean.
