As the idea of the particular duration of anything is, an idea of that portion of infinite duration which passes during the existence of that thing; so the time when the thing existed is, the idea of that space of duration which passed between some known and fixed period of duration, and the being of that thing.
Eta edozein gauzaren iraupen partikularraren ideia gauza horrek existitzen dirauen artean gertatzen den iraupen infinitu horren zatiaren ideia den bezala, gauza existitu zeneko denbora honako hau da, alegia, iraupen aldi jakin eta zehatz baten eta gauza horren izatearen artean iragandako iraupen tartea.
