Exploring Aristotle's philosophical method and the merits of his conclusions, Irwin here shows how Aristotle defends dialectic against the objection that it cannot justify a metaphysical realist's claims. He focuses particularly on Aristotle's metaphysics, epistemology, philosophy of mind, and ethics, stressing the connections between doctrines that are often discussed separately.

Following strict rules of interpretation, this book focuses on the ideas in Plato's early and middle dialogues that lie within the fields now called logic and methodology, specifically elenchus and dialectic and the method of hypothesis.

In this dialogue Plato shows the pretensions of the leading sophist, Protagoras, challenged by the critical arguments of Socrates. The dialogue broadens out to consider the nature of the good life and the role of intellect and pleasure.

The "Protagoras," like several of the Dialogues of Plato, is put into the mouth of Socrates, who describes a conversation which had taken place between himself and the great Sophist at the house of Callias-'the man who had spent more upon the Sophists than all the rest of the world'-and in which the learned Hippias and the grammarian Prodicus had also shared, as well as Alcibiades and Critias, both of whom said a few words-in the presence of a distinguished company (...) consisting of disciples of Protagoras and of leading Athenians belonging to the Socratic circle. The dialogue commences with a request on the part of Hippocrates that Socrates would introduce him to the celebrated teacher. He has come before the dawn had risen-so fervid is his zeal. Socrates moderates his excitement and advises him to find out 'what Protagoras will make of him, ' before he becomes his pupil. Presented here is the classic introduction and translation of Benjamin Jowett. (shrink)

The paper's thesis is that dialogue is not an adequate model for all types of argument. The position of Walton is taken as the contrary view. The paper provides a set of descriptions of dialogues in which arguments feature in the order of the increasing complexity of the argument presentation at each turn of the dialogue, and argues that when arguments of great complexity are traded, the exchanges between arguers are turns of a dialogue only in an extended or metaphorical (...) sense. It argues that many of the properties of engaged back-and-forth exchanges of paradigmatic argument dialogues are not found in ‘solo’ arguments, and that at least some of the norms appropriate to the former type of argument, such as some of the pragma-dialectical rules of van Eemeren and Grootendorst's model, do not apply to the latter.
