Now, says Thrasylus, the genuine dialogues are fifty-six in all, if the Republic be divided into ten and the Laws into twelve. Favorinus, however, in the second book of his Miscellaneous History declares that nearly the whole of the Republic is to be found in a work of Protagoras entitled Controversies.From iii. 37 we infer that Favorinus drew upon Aristoxenus for this wildly improbable assertion. This gives nine tetralogies, if the Republic takes the place of one single work and the Laws of another. His first tetralogy has a common plan underlying it, for he wishes to describe what the life of the philosopher will be. To each of the works Thrasylus affixes a double title, the one taken from the name of the interlocutor, the other from the subject.

This tetralogy, then, which is the first, begins with the Euthyphro or On Holiness, a tentative dialogue; the Apology of Socrates, an ethical dialogue, comes second; the third is Crito or On what is to be done, ethical; the fourth Phaedo or On the Soul, also ethical. The second tetralogy begins with Cratylus or On Correctness of Names, a logical dialogue, which is followed by Theaetetus or On Knowledge, tentative, the Sophist or On Being, a logical dialogue, the Statesman or On Monarchy, also logical. The third tetralogy includes, first, Parmenides or On Ideas, which is logical, next Philebus or On Pleasure, an ethical dialogue, the Banquet or On the Good, ethical, Phaedrus or On Love, also ethical.
