Protagoras was an important Greek thinker of the fifth century BC, the most famous of the so called Sophists, though most of what we know of him and his thought comes to us mainly through the dialogues of his strenuous opponent Plato. In this book, Ugo Zilioli offers a sustained and philosophically sophisticated examination of what is, in philosophical terms, the most interesting feature of Protagoras' thought for modern readers: his role as the first Western thinker to argue for relativism. Zilioli relates Protagoras' relativism with modern forms of relativism, in particular the 'robust relativism' of Joseph Margolis, gives an integrated account both of the perceptual relativism examined in Plato's Theaetetus and the ethical or social relativism presented in the first part of Plato's Protagoras and offers an integrated and positive analysis of Protagoras' thought, rather than focusing on ancient criticisms and responses to his thought. This is a deeply scholarly work which brings much argument to bear to the claim that Protagoras was and remains Plato's subtlest philosophical enemy.

Table of contents

It was Nietzsche who first identified the similarities between the radical sophistry of antiquity and the contemporary relativism that has come to characterize modern thought. The anti-foundationalism of contemporary thought can be said to have been born with the Sophists, and, of all the Sophists who have come down to us, Protagoras is the most famous and challenging of them. Robert Bartlett s masterful book is the first to examine Plato s Protagoras and Theaetetus together to uncover what lies at the heart of Protagoras teaching, both its moral and political components and its theoretical and epistemological groundings. His superb exegesis of these two dialogues allows one to see more clearly the power of radical relativism: its strengths and its deficiencies. Bartlett notes that political philosophy has been supplanted in the modern era either by the study of the history of political philosophy or by relativism. Although "Understanding Political Philosophy and Sophistry" can certainly be taken as an example of the former, it is much more than that. It seeks to uncover what Socrates, in responding to that teaching, begins to reveal of his own understanding and characteristic activity. It helps us begin to understand, in other words, the phenomenon of philosophy, not just as a system of thought, but as Socrates lived it."

The academic world has been plagued in recent years by scepticism about truth and knowledge. Paul Boghossian, in his long-awaited first book, sweeps away relativist claims that there is no such thing as objective truth or knowledge, but only truth or knowledge from a particular perspective. He demonstrates clearly that such claims don't even make sense. Boghossian focuses on three different ways of reading the claim that knowledge is socially constructed - one as a thesis about truth and two about justification. And he rejects all three. The intuitive, common-sense view is that there is a way things are that is independent of human opinion, and that we are capable of arriving at belief about how things are that is objectively reasonable, binding on anyone capable of appreciating the relevant evidence regardless of their social or cultural perspective. Difficult as these notions may be, it is a mistake to think that recent philosophy has uncovered powerful reasons for rejecting them. This short, lucid, witty book shows that philosophy provides rock-solid support for common sense against the relativists; it will prove provocative reading throughout the discipline and beyond.

Protagoras of Abdera, Socrates’ older contemporary, is regarded as one of the most prominent representatives of the so-called sophistic movement. Instead of simply accepting the biased reports given by Plato and Aristotle about this sophist, the contributors to this volume review the complicated doxographical situation and make a case for Protagoras as a philosopher in his own right. Two major themes of this volume are Protagoras’ relativism and his case for a moral and political ideal, both of which are contrasted with the metaphysical idealism of his future opponents in the Academy and the mundane conventionalism typically associated with the sophists. It turns out that rather than a parasitic force of intellectual subversion, Protagoras may have been a prolific and original thinker aiming at a coherent and comprehensive view of man’s place in the world.

This book offers an introduction to the Sophists of fifth-century Athens and a new overall interpretation of their thought. Since Plato first animadverted on their activities, the Sophists have commonly been presented as little better than intellectual mountebanks - a picture which Professor Kerferd forcefully challenges here. Interpreting the evidence with care, he shows them to have been part of an exciting and historically crucial intellectual movement. At the centre of their teaching was a form of relativism, most famously expressed by Protagoras as 'Man is the measure of all things', and which they developed in a wide range of views - on knowledge and argument, virtue, government, society, and the gods. On all these subjects the Sophists did far more than simply provoke Plato to thought. Their contributions were substantial and serious; they inaugurated the debate on many central philosophical questions and decisively shifted the focus of philosophical attention from the cosmos to man.
