Now the essential point in this system of Categories, which distinguishes it from the old rhapsodical collection without any principle, and for which alone it deserves to be considered as philosophy, consists in this: that by means of it the true significance of the pure concepts of the understanding and the condition of their use could be precisely determined.
Baina kategorien sistema honetan esentziala dena, inolako printzipiorik gabe jokatu zuen rapsodia zahar hartatik bereizten duena, eta filosofian aintzakotzat hartua izatea merezi duena, zera da: alegia, horren bitartez zehatz-mehatz determina daitekeela adimen-kontzeptu hutsen egiazko esanahia eta horiek erabiltzeko baldintza.
