Indiscernible Tolerance Arguments

Abstract

This is the first of two chapters devoted to a special subclass of Tolerance Puzzles based on ‘indiscernible modality’, on which qualitative truths are automatically necesssary. The interest in these puzzles lies in the fact that there is a distinctive argument for Non-contingency based on the premise that properties like being a table are qualitative. This chapter explores the options for resolving the puzzles compatible with accepting that premise, and hence Non-contingency for indiscernible modality.
