For Friday, re-read Conee's chapter on fatalism. There is a writing assignment that was announced in class.
Today we wound up talking about this topic in thinking about the First Assumption of the sea battle argument (p. 24) and LEM (p. 27).
There is wide agreement that a term is vague to the extent that it has borderline cases. This makes the notion of a borderline case crucial in accounts of vagueness. I shall concentrate on an historical characterization of borderline cases that most commentators would accept. Vagueness will then be contrasted with ambiguity and generality. This will clarify the nature of the philosophical challenge posed by vagueness. I will then discuss some rival theories of vagueness with an emphasis on many-valued logic, supervaluationism and contextualism. I will conclude with the issue of whether all vagueness is linguistic.
