Abstract: Many prima facie solutions of the Sorites paradox face a revenge problem, that is, the recurrence of the paradox at a different level. The most notorious case is that of higher-order vagueness, where each added order leads to a new Sorites and the assumption of infinite orders to the so-called higher-order vagueness paradoxes. In my talk I aim to show (i) how these paradoxes result from the confusion of two paradigms of borderline cases: higher-order vagueness (using iterated modalities) and borderline nestings (using mixed-order non-empty predicates); (ii) how, once the characteristics of borderline nestings are removed from the description of higher-order vagueness, the paradoxes disappear. For this purpose, I introduce the -- perhaps only -- coherent theory of higher-order vagueness, i.e. that of columnar higher-order vagueness and explain its basic characteristics. Finally I provide the basics of a family of formal semantics that manifest the infrastructure for these revenge-evading theories, starting with a bivalent normal modal system (or Kripke semantics) and hinting how this could be modified to trivalent Kripke semantics, and/or to systems of three-valued logics with a bivalent modal fragment.
