5. Theory of Logic / D. Assumptions for Logic / 1. Bivalence

18840	When faced with vague statements, Bivalence is not a compelling principle [Rumfitt]
	Full Idea: I do not regard Bivalence, when applied to vague statements, as an intuitively compelling principle which we ought to try to preserve.
	From: Ian Rumfitt (The Boundary Stones of Thought [2015], 8.7)
	A reaction: The point of Rumfitt's book is to defend classical logic despite failures of bivalence. He also cites undecidable concepts such as the Continuum Hypothesis.
