1. The Psychology of Vagueness: Borderline Cases and Contradictions.Sam Alxatib & Francis Jeffry Pelletier - 2011 - Mind and Language 26 (3):287-326.
    In an interesting experimental study, Bonini et al. (1999) present partial support for truth-gap theories of vagueness. We say this despite their claim to find theoretical and empirical reasons to dismiss gap theories and despite the fact that they favor an alternative, epistemic account, which they call ‘vagueness as ignorance’. We present yet more experimental evidence that supports gap theories, and argue for a semantic/pragmatic alternative that unifies the gappy supervaluationary approach together with its glutty relative, the subvaluationary approach.

    Remarks on exhaustification and embedded free choice.Sam Alxatib - 2023 - Natural Language Semantics 31 (4):291-314.
    Some sentences that contain disjunctions imply that their disjunct-alternatives are false, while others imply that they are true. Recent work on scalar implicature has been guided by the behavior of such constructions. In this paper I consider examples in which free choice disjunctions (phrases of the form _allowed to A or B_) appear in various intensional contexts. I discuss the significance of the findings in light of current views of exhaustification.

  3. Acceptable Contradictions: Pragmatics or Semantics? A Reply to Cobreros et al. [REVIEW]Sam Alxatib, Peter Pagin & Uli Sauerland - 2013 - Journal of Philosophical Logic 42 (4):619-634.
    Naive speakers find some logical contradictions acceptable, specifically borderline contradictions involving vague predicates such as Joe is and isn’t tall. In a recent paper, Cobreros et al. (J Philos Logic, 2012) suggest a pragmatic account of the acceptability of borderline contradictions. We show, however, that the pragmatic account predicts the wrong truth conditions for some examples with disjunction. As a remedy, we propose a semantic analysis instead. The analysis is close to a variant of fuzzy logic, but conjunction and disjunction (...)
