The stilted logical demonstration is always foreign to the matter, and is generally soon forgotten, without weakening our conviction. It might indeed be dispensed with altogether without diminishing the evidence of geometry, for this is always quite independent of such demonstration, which never proves anything we are not convinced of already, through another kind of knowledge.
inola ere ez da hankapaloen gainean aurrera egiten duen frogapen logikoa, zeina gaiarekiko arrotz, laster ahazten baita gehienetan, konbentzimenduaren kalterik gabe, eta ezabatu ere egin liteke, geometriaren ebidentzia horrenbestez gutxitu gabe, zeren hartatik erabat dependentea baita eta beste ezagutza-era baten bitartez konbentzimendu osokoa duen hura bakarrik frogatzen baitu beti aldez aurretik:
