The Logic of Δ
vagueness, modality, modal logic, aoristic modality, aoristic modal logic
I argue that the ‘aoristic’ operators, which are intended to describe the logic of vagueness, do not form a standard modal logic. I redefine the operators so that they do form a standard modal logic, provide a semantics of that logic, and argue that the logic is not as strong as standardly claimed.
