And as it is true to say of the other sciences too, without qualification, that they deal with such and such a subject-not with what is accidental to it (e.g. not with the pale, if the healthy thing is pale, and the science has the healthy as its subject), but with that which is the subject of each science-with the healthy if it treats its object qua healthy, with man if qua man:-so too is it with geometry;
Eta gainerako zientziak 35) objektu zehatz batez arduratzen direla-ez akzidenteaz (adibidez, ez zuriaz, osasuntsua zuria baldin bada eta zientzia osasuntsu denaz 1078a) arduratzen bada), zientzia bakoitzaren objektuaz beraz baizik (osasuntsu denaz, osasuntsu den aldetik ikertzen badu, eta gizakiaz, gizakia den aldetik ikertzen badu)-, hau besterik gabe esatea egia den bezala, geometriaz ere gauza bera esan daiteke:
