But this is no derogation to their truth and certainty; no more than it is to the truth or certainty of the three angles of a triangle being equal to two right ones because it is not so evident as "the whole is bigger than a part," nor so apt to be assented to at first hearing.
Baina inola ere ez da hau beraien egiaren ez ziurtasunaren derogazioa, triangelu baten hiru angeluak bi zuzen adina direla dioen egiaren derogazioa ez den bezalaxe, "osoa bere zatia baino handiagoa izatea" bezain begi-bistakoa edo lehenbizi entzutean baiesteko hura bezain egokia ez delako soilik.
