Diamond received her Bachelor of Arts degree from Swarthmore College in 1957 and her Bachelor of Philosophy degree from St Hugh's College, Oxford (where her tutor was Paul Grice[citation needed]), in 1961.
Diamond's writings on both "early" (Tractatus Logico-Philosophicus era) and "late" (Philosophical Investigations era) Wittgenstein have made her a leading influence in the New Wittgensteinian approach advanced by Alice Crary, James F. Conant, and others.
Diamond has published a collection of essays titled The Realistic Spirit: Wittgenstein, Philosophy, and the Mind.
She is the editor of Wittgenstein's Lectures on the Foundations of Mathematics: Cambridge 1939, a collection of lectures assembled from the notes of Wittgenstein's students Norman Malcolm, Rush Rhees, Yorick Smythies, and R. G. Bosanquet.
Wittgenstein and the Moral Life: Essays in Honor of Cora Diamond (edited by Alice Crary[4]) features essays by Crary, John McDowell, Martha Nussbaum, Stanley Cavell, and James F. Conant, among others.
