Hobbes himself characterises his completely empirical method of thought very remarkably by the fact that in his book "De Principiis Geometrarum" he denies all pure mathematics properly so called, and obstinately maintains that the point has extension and the line has breadth, and we can never show him a point without extension or a line without breadth. Thus we can just as little impart to him the a priori nature of mathematics as the a priori nature of right, because he shuts himself out from all knowledge which is not empirical.
eta guk Hobbes berorri, zeinak bere pentsatzeko era enpirikoki osotua guztiz ohargarriro ezaugarritzen baitu bere liburuan benetako matematika hutsa ukatuz, eta puntuak hedadura duela eta lerroak zabalera eta ezin diogula inoiz hedadura gabeko puntu bat eta zabalera gabeko lerro bat aurrean jarri kaskagor baieztatuz, horrela ezin diogu matematikaren aprioritatea ulertarazi, zuzenbidearen aprioritatea ezin diogun bezala, zeren erabat itxirik baitago ezagutza enpirikoa ez den guztira.
