The principle, "a straight line is the shortest between two points," presupposes that the line is subsumed under the concept of quantity, which certainly is no mere intuition, but has its seat in the understanding alone, and serves to determine the intuition (of the line) with regard to the judgments which may be made about it, relatively to their quantity, that is, to plurality (as judicia plurativa). For under them it is understood that in a given intuition there is contained a plurality of homogenous parts.
"lerro zuzena da bi punturen artean laburrena" dioenak ere, aurre suposatzen du, lerroa handitasun-kontzeptuaren azpian subsumitzen dela; kontzeptu hori, berriz, ez da inola ere intuizio soila, aitzitik adimenean dauka bere kokalekua, eta balio du, intuizioa (lerroarena) determinatzeko, honetaz eman daitezkeen judizioei buruz, horren kantitatearen ikuspegitik, hots kontuan hartuz horren pluraltasuna (judicia plurativa gisa); horrekin ulertu nahi baita, ezen emandako intuizio batean elemetu homogeno asko egoten direla.
