On the Meeting for the sake of seeking Instruction (16-20)

And music will teach what is inharmonious in the way of rhythm, and what is ill arranged in harmony, and, rejecting all that is out of tune and all that is inconsistent with melody, will guide what was previously discordant to concord. And geometry, sowing the seeds of equality and just proportion in the soul, which is fond of learning, will, by means of the beauty of continued contemplation, implant in you an admiration of justice.

And rhetoric, having sharpened the mind for contemplation in general, and having exercised and trained the faculties of speech in interpretation and explanation, will make man really rational, taking care of that peculiar and especial

And dialectic science, which is the sister, the twin sister of rhetoric, as some persons have called it, separating true from false arguments, and refuting the plausibilities of sophistical arguments, will cure the great disease of the soul, deceit.

For perhaps, I say, as has happened to many, we shall become known to the queenly virtues by means of their subjects and handmaidens.

Do you not see that our bodies do not use solid and costly food before they have first, in their age of infancy, used such as had no variety, and consisted merely of milk?

Now the first characteristics of the intermediate instruction are represented by two symbols, the race and the name. As to race, the handmaiden is an Egyptian, and her name is Hagar; and this name, being interpreted, means "emigration." For it follows of necessity that the man who delights in the encyclical contemplations, and who joins himself as a companion to varied learning, is as such enrolled under the banners of the earthly and Egyptian body; and that he stands in need of eyes in order to see and to read, and of ears in order to attend and to hear, and of his other external senses, in such a manner as to be able to unfold each of the objects of the external sense.
