Stephen Hetherington is Emeritus Professor of Philosophy, in the School of Humanities and Languages. B.A. (Hons -- Class I) (Sydney),  B.Phil. (Oxford),  M.A., Ph.D. (Pittsburgh). And FAHA. From December 20133 until March 2022, he was the Editor-in-Chief of the Australasian Journal of Philosophy, one of the world's leading philosophy journals. Currently, he is Editor-in-Chief, for Bloomsbury, of the book series Critical Introductions to Contemporary Epistemology, as well as, for Cambridge University Press, of their series, Elements in Epistemology.

His main interests are in epistemology and, to a lesser extent, metaphysics. He has published on many aspects of epistemology, including knowledge-how, meta-epistemology, philosophical knowledge, various forms of scepticism, the Gettier problem and defining knowledge, non-absolute knowledge (grades or degrees of knowledge), induction, a priori knowledge, and fallibilism. His research in metaphysics has been mainly on death, free will, and moral responsibility.

Hetherington has written several monographs: Epistemology's Paradox (Rowman & Littlefield, 1992), Good Knowledge, Bad Knowledge (Oxford University Press, 2001), Self-Knowledge (Broadview Press, 2007), How To Know (Wiley-Blackwell, 2011), Knowledge and the Gettier Problem (Cambridge University Press, 2016), and Defining Knowledge (Cambridge University Press, 2022). He has edited several others, including Epistemology Futures (Oxford University Press, 2006), The Gettier Problem (Cambridge University Press, 2018), and Extreme Philosophy (Routledge, 2024). He is also the general editor of the four-volume The Philosophy of Knowledge: A History (Bloomsbury, 2019), one volume of which is Knowledge in Contemporary Philosophy, co-edited with Markos Valaris.

He has also written several introductory books, mainly -- but not only -- on epistemology: Knowledge Puzzles (Westview, 1996), Reality? Knowledge? Philosophy! (Edinburgh University Press, 2003), Self-Knowledge (Broadview, 2007), Yes, But How Do You Know? (Broadview, 2009), What Is Epistemology? (Polity, 2019), and Being Philosophical (Polity, 2024). 

A collection of several of his published papers, along with two new ones and an interview about his life and work, has also appeared: Stephen Hetherington on Epistemology (Bloomsbury, 2024).
