A few of the books I have used with links to more info on each book:
The Collected Dialogs of Plato: Including the Letters (Bollingen Series LXXI)
This is the collection edited by Hamilton and Cairns. I have used this collection of the Dialogs of Plato for thirty five years. I bought my first copy of this book for 25 cents at a library book sale in 1982. Translations by Benjamin Jowett.
This translation is a more up to date work of translation edited by John M. Cooper. It is a more useful translation for the modern reader.
Plato: Euthyphro. Apology. Crito. Phaedo. Phaedrus (Loeb Classical Library)
The Loeb Classical Library has all of Plato's dialogs with the Greek text on the left page and the English text on the right page.
Socratic Epistemology: Explorations of Knowledge-Seeking by Questioning
This collection of essays by Hintikka offers observations about the structure of inquiry, game-theoretical semantics, and epistemic logic in an exploration of how we gain knowledge through questions. The idea of replacing the concept of knowledge with the concept of information is a fundamentally important refinement of epistemology. A familiarity with logic notation and concepts is required.
Socrates: Ironist and Moral Philosopher
Socratic Studies
This is an excellent, well written book, a must read from one of the better scholars. He provides a very thoughtful discussion of Socratic Irony, the problem of the historical Socrates, changes in his method through Plato, and more. Even if you disagree with Vlastos, you owe it to your mind to be interacting with Vlastos.
This is Vlastos' companion book to "Socrates" above. Four ground-breaking papers which laid the basis for his understanding of Socrates are collected here, in revised form: they examine Socrates' elenctic method of investigative argument, his disavowal of knowledge, his concern for definition, and the complications of his relationship with the Athenian democracy. The fifth chapter is a new and provocative discussion of Socrates' arguments in the Protagoras and Laches. The epilogue 'Socrates and Vietnam' suggests that Socrates was not, as Plato claimed, the most just man of his time. The papers have been prepared for publication by Professor Myles Burnyeat with the minimum of editorial intervention.
Socratic Perplexity: And the Nature of Philosophy
A great read on the nature of the perplexity that Socrates shared and induced in his conversations and its relationship to the nature of the human philosophical quest.
"Dana Villa argues that we need to place more value on a form of conscientious, moderately alienated citizenship invented by Socrates, one that is critical in orientation and dissident in practice." Villa does this as he works through the thought of Socrates, John Stuart Mill, Nietzsche, Max Weber, Arendt and Strauss and more.
The Socratic Citizen: A Theory of Deliberative Democracy
Gundersen asserts that political deliberation is central to democracy as a form of discourse and is best thought of as a two-person affair, or a dyad.
Socratic Wisdom: The Model of Knowledge in Plato's Early Dialogs
Benson argues that the most distinctive features of the early dialogs of Plato are epistemological, not ethical, and offers a model of Knowledge in Plato's early dialogs
Socrates (Arguments of the Philosophers)
Gerasimos Xenophon Santas gives us a detailed and systematic analysis of the questions, assumptions, definitions and arguments in Plato, along with a discussion of Socratic ethics in Part three. It was while reading this book for an independent study I was designing in college (Systematic Dialectic) in the early 1990's that I realized the Socratic method could be used for live conversation with a systematically useful and understandable methodology.
Dialogue and Discovery. A Study in Socratic Method (SUNY Series in Philosophy)
Seeskin presents a therapeutic model of the Socratic elenchus where Socratic dialogue is not merely a test of intellect in search of correct definitions. It is also a test of human character.
Teach Like Socrates: Guiding Socratic Dialogs and Discussions in the Classroom
Erick Wilberding, PhD is teacher with 20 years experience teaching in middle school and high school. This book is an interesting and useful experiment by an experienced teacher to bring Socratic dialogue into the classroom.
Socratic Circles: Fostering Critical and Creative Thinking in Middle and High School
Matt Copeland outlines the process of setting up Socratic Circles in the classroom (Middle/High School)
