" For example, there was once a pagan master who was devoted to an art, that of mathematics, to which he had devoted all his powers. He was sitting by the embers, making calculations and practicing his art, when a man came along who drew a sword and, not knowing that it was the master, said: "Quick, tell me your name or I will kill you!" The master was to absorbed to see or hear the foe or to catch what he said; he was unable to utter a word, and to say: "My name is so and so". And so the enemy, having cried out several times and got no answer, cut off his head. And this was to acquire a mere natural science. How much more then should we withdraw from all things in order to concentrate all our powers on perceiving and knowing the one infinite, uncreated, eternal truth! "
