Edmund Gettier's 1963 verdict about what knowledge is not has become an item of philosophical orthodoxy, accepted by philosophers as a genuine epistemological result. It assures us that - contrary to what Plato and later philosophers have thought - knowledge is not merely a true belief well supported by epistemic justification. But that orthodoxy has generated the Gettier problem - epistemology's continuing struggle to understand how to accommodate Gettier's apparent result within an improved conception of knowledge. In this book, Stephen Hetherington argues that none of epistemology's standard attempts to solve that problem have succeeded: he shows how subtle yet fundamental mistakes - regarding explication, methodology, properties, modality, and fallibility - have permeated those responses to Gettier's challenge. His fresh and original book outlines a new way of solving the problem, and an improved grasp of Gettier's challenge and its significance is the result. In a sense, Plato can now embrace Gettier.

Post-Gettier epistemology is increasingly modalized epistemology – proposing and debating modally explicable conditionals with suitably epistemic content (an approach initially inspired by Robert Nozick's 1981 account of knowledge), as needing to be added to 'true belief' in order to define or understand knowing's nature. This Element asks whether such modalized attempts – construed as responding to what the author calls Knowing's Further Features question (bequeathed to us by the Meno and the Theaetetus) – can succeed. The answer is that they cannot. Plato's and Aristotle's views on definition reinforce that result. Still, in appreciating this, we might gain insight into knowing's essence. We might find that knowledge is, essentially, nothing more than true belief.
