Plato’s Republic probably one of the titular titles anyone thinks of when they contemplate ancient philosophy—and for good reason. Unlike contemporaries such as Zeno and Aristotle, Plato’s theories of forms and intense commitment to a political meritocracy still have meaning and application, even over two thousand years after they were written. And unlike even more “modern” philosophers like Kant or Mill, Plato’s political and ethical theories are startlingly modern and mostly devoid of unsavory biases like apologetics for colonialism or musings on the inherent inferiority of the female sex. Plato’s Republic is a masterwork of epistemology, metaphysics, ethics, and political philosophy. Any inspiring philosopher really ought to have this title under his or her belt—not only for posterity, but also because it truly is good enough to stand the test of the millennia solely on its own merits.— Jennie
Some dialogues of Plato are of so various a character that their relation to the other dialogues cannot be determined with any degree of certainty. The Theaetetus, like the Parmenides, has points of similarity both with his earlier and his later writings. The perfection of style, the humour, the dramatic interest, the complexity of structure, the fertility of illustration, the shifting of the points of view, are characteristic of his best period of authorship. The vain search, the negative conclusion, the figure of the midwives, the constant profession of ignorance on the part of Socrates, also bear the stamp of the early dialogues, in which the original Socrates is not yet Platonized. Had we no other indications, we should be disposed to range the Theaetetus with the Apology and the Phaedrus, and perhaps even with the Protagoras and the Laches. But when we pass from the style to an examination of the subject, we trace a connection with the later rather than with the earlier dialogues.
