Essentialism and Logical Consequence
According to an increasingly popular view, the source of logical necessity is to be found in the essences of logical entities. One might be tempted to extend the view further in using it to tackle fundamental questions surrounding logical consequence. This chapter enquires: how does a view according to which the facts about logical consequence are determined by the essences of logical entities look in detail? Are there any more or less obvious pr…
Degrees of belief, expected and actual
A framework of degrees of belief, or credences, is often advocated to model our uncertainty about how things are or will turn out. It has also been employed in relation to the kind of uncertainty or indefiniteness that arises due to vagueness, such as when we consider “a is F” in a case where a is borderline F. How should we understand degrees of belief when we take into account both these phenomena? Can the right kind of theory of the semantics …

Teaching & Learning Guide for: Vagueness: Supervaluationism
This guide accompanies the following article(s): Rosanna Keefe, ‘Vagueness: Supervaluationism.’ Philosophy Compass 3.2 (2008): 315–24, 10.1111/j.1747‐9991.2008.00124.x Author’s Introduction Vagueness is an extremely widespread feature of language, famously associated with the sorites paradox. One instance of this paradox concludes that a single grain of sand is a heap of sand, by starting with a large heap of sand and invoking the plausible premi…
Vagueness: Supervaluationism
This piece gives an overview of the supervaluationist theory of vagueness. According to that theory, a sentence is true if and only if it is true on all ways of making it precise. This yields borderline case predications that are neither true nor false, but yet classical logic is preserved almost entirely. The article presents the view and some of its merits and briefly compares it with other theories of vagueness. It raises issues about higher-o…
The Concept of ‘Ignorance’ In Jean-Paul Sartre's Notebooks for an Ethics and Truth and Existence
Etude de la conception de l'ignorance developpee par Sartre dans ses «Cahiers pour une morale», a partir des notions de moralite, oppression et authenticite, d'une part, et dans «Verite et existence», a partir des notions de condition originaire de l'homme, choix et necessite, d'autre part
Theories of Vagueness (Cambridge Studies in Philosophy)
"Most expressions in natural language are vague. But what is the best semantic treatment of terms like 'heap', 'red' and 'child'? And what is the logic of arguments involving this kind of vague expression? These questions are receiving increasing philosophical attention, and in this timely book Rosanna Keefe explores the questions of what we should want from an account of vagueness and how we should assess rival theories. Her discussion ranges wi…
