    In this contribution, I explore the treatment that Plato devotes to Protagoras’ relativism in the first section of the Theaetetus (151 E 1–186 E 12) where, among other things, the definition that knowledge is perception is put under scrutiny. What I aim to do is to understand the subtlety of Plato’s argument about Protagorean relativism and, at the same time, to assess its philosophical significance by revealing the inextric¬ability of ontological and epistemological aspects on which it is built…Read more

    The wooden Horse: the Cyrenaics in the Theaetetus
    In G. Boys-Stones, C. Gill & D. El-Murr (eds.), The Platonic Art of philosophy, Cambridge University Press. 2013.
    In this contribution, I aim to show how locating the Platonic dialogues in the intellectual context of their own time can illuminate their philosophical content. I seek to show, with reference to a specific dialogue (the Theaetetus), how Plato responds to other thinkers of his time, and also to bring out how, by reconstructing Plato’s response, we can gain deeper insight into the way that Plato shapes the structure and form of his argument in the dialogue. In particular, I argue that the subtle…Read more

    The Cyrenaics
    Acumen Publishing. 2012.
    The Cyrenaic school of philosophy (named after its founder Aristippus’ native city of Cyrene in North Africa) flourished in the fifth and fourth centuries BCE.

The book begins by introducing the main figures of the Cyrenaic school beginning with Aristippus and by setting them into their historical context. Once the reader is familiar with those figures and with the genealogy of the school, the book offers an…Read more

    In this paper I offer a reconstruction of the account of meaning and language the Cyrenaics appear to have defended on the basis of a famous passage of Sextus, as well as showing the philosophical parentage of that account

    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. Zi…Read more

    In the two golden centuries that followed the death of Socrates, ancient philosophy underwent a tremendous transformation that culminated in the philosophical systematizations of Plato, Aristotle and the Hellenistic schools. Fundamental figures other than Plato were active after the death of Socrates; his immediate pupils, the Socratics, took over his legacy and developed it in a variety of ways. This rich philosophical territory has however been left largely underexplored in the scholarship. Th…Read more
