Rush Rhees (1905-89) was one of Wittgenstein's closest friends and his literary executor. He taught at Swansea from 1940 to 1966. Amongst Wittgenstein's posthumous works edited by Rhees are Remarks on the Foundations of Mathematics (1956), Blue and Brown Books (1958), Philosophical Remarks (1964), Lecture On Ethics (1965) and Philosophical Grammar (1969). Rhees is also the author of Discussions of Wittgenstein (1970, 1996) and Wittgenstein and the Possibility of Discourse (1998). D. Z. Phillips is Professor of Philosophy Emeritus and Rush Rhees Professor Emeritus at the University of Wales, Swansea, and Danworth Professor of the Philosophy of Religion at Claremont Graduate School, California. He has published widely in the philosophy of religion and ethics; some of his more recent books include Interventions in Ethics (1992), Wittgenstein and Religion (1993) and Religion and the Hermeneutics of Contemplation (2001). He is also editor of the Blackwell journal Philosophical Investigations.

"This book contains illuminating remarks and a novel perspective on an important and widely discussed classic. And it has a special authority, being the work of one of the author's best students and closest friends." William Brenner, Old Dominion University, Norfolk, Virginia "This book contains two remarkable and original contributions by Rush Rhees and D. Z. Phillips to the burgeoning scholarship on Wittgenstein's On Certainty. I recommend it strongly." Avrum Stroll, University of California, San Diego
