Then now comes the question,-How shall we create our rulers; what

way is there from darkness to light? The change is effected by

philosophy; it is not the turning over of an oyster-shell, but

the conversion of a soul from night to day, from becoming to

being. And what training will draw the soul upwards? Our former

education had two branches, gymnastic, which was occupied with

the body, and music, the sister art, which infused a natural

harmony into mind and literature; but neither of these sciences

gave any promise of doing what we want. Nothing remains to us but

that universal or primary science of which all the arts and

sciences are partakers, I mean number or calculation. 'Very

true.' Including the art of war? 'Yes, certainly.' Then there is

something ludicrous about Palamedes in the tragedy, coming in and

saying that he had invented number, and had counted the ranks and

set them in order.
