I am not unaware that there are other ways in which certain writers classify the dialogues. For some dialogues they call dramatic, others narrative, and others again a mixture of the two. But the terms they employ in their classification of the dialogues are better suited to the stage than to philosophy. Physics is represented by the Timaeus, logic by the Statesman, Cratylus, Parmenides and Sophist, ethics by the Apology, Crito, Phaedo, Phaedrus and Symposium, as well as by the Menexenus, Clitophon, the Epistles, Philebus, Hipparchus and the Rivals, and lastly politics by the Republic, the Laws, Minos, Epinomis, and the dialogue concerning Atlantis.i.e. Critias.

To the class of mental obstetrics belong the two Alcibiades, Theages, Lysis and Laches, while the Euthyphro, Meno, Io, Charmides and Theaetetus illustrate the tentative method. In the Protagoras is seen the method of critical objections; in the Euthydemus, Gorgias, and the two dialogues entitled Hippias that of subversive argument. So much then for dialogue, its definition and varieties.

Again, as there is great division of opinion between those who affirm and those who deny that Plato was a dogmatist, let me proceed to deal with this further question.
