these divisions is dialectic, not rhetoric, and it must be seen what part of rhetoric may have been left out. When Socrates and Phaedrus proceed to recount the various tools of speechmaking as written down by the great orators of the past, starting with the "Preamble" and the "Statement Facts" and concluding with the "Recapitulation", Socrates states that the fabric seems a little threadbare. He goes on to compare one with only knowledge of these tools to a doctor who knows how to raise and lower a body's temperature but does not know when it is good or bad to do so, stating that one who has simply read a book or came across some potions knows nothing of the art. One who knows how to compose the longest passages on trivial topics or the briefest passages on topics of great importance is similar, when he claims that to teach this is to impart the knowledge of composing tragedies; if one were to claim to have mastered harmony after learning the lowest and highest notes on the lyre, a musician would say that this knowledge is what one must learn before one masters harmony, but it is not the knowledge of harmony itself. This, then, is what must be said to those who attempt to teach the art of rhetoric through "Preambles" and "Recapitulations"; they are ignorant of dialectic, and teach only what is necessary to learn as preliminaries. They go on to discuss what is good or bad in writing. Socrates tells a brief legend, critically commenting on the gift of writing from the Egyptian god Theuth to King Thamus, who was to disperse Theuth's gifts to the people of Egypt. After Theuth remarks on his discovery of writing as a remedy for the memory, Thamus responds that its true effects are likely to be the opposite; it is a remedy for reminding, not remembering, he says, with the appearance but not the reality of wisdom. Future generations will hear much without being properly taught, and will appear wise but not be so, making them difficult to get along with. No written instructions for an art can yield results clear or certain, Socrates states, but rather can only remind those that already know what writing is about. Furthermore, writings are silent; they cannot speak, answer questions, or come to their own defense. Accordingly, the legitimate sister of this is,
