We develop and defend a new approach to counterlogicals. Non-vacuous counterlogicals, we argue, fall within a broader class of counterfactuals known as counterconventionals . Existing semantics for counterconventionals (developed by Einheuser ( Philosophical Studies, 127 (3), 459–482 ( 2006 )) and (Kocurek et al. Philosophers’ Imprint , 20(22), 1–27 ( 2020 )) allow counterfactuals to shift the interpretation of predicates and relations. We extend these theories to counterlogicals by allowing counterfactuals to shift the interpretation of logical vocabulary. This yields an elegant semantics for counterlogicals that avoids problems with the usual impossible worlds semantics. We conclude by showing how this approach can be extended to counterpossibles more generally.

反逻辑作为反传统

我们开发并捍卫一种新的反逻辑方法。我们认为，非空洞的反逻辑属于更广泛的反事实类别，称为反传统。反传统的现有语义（由 Einheuser ( Philosophical Studies, 127 (3), 459–482 ( 2006 ) ）和 (Kocurek et al. Philosophers' Imprint , 20(22), 1–27 (2020 ) 开发）允许转移反事实谓词和关系的解释。我们通过允许反事实改变逻辑词汇的解释将这些理论扩展到反逻辑。这为反逻辑产生了优雅的语义，避免了通常不可能世界的语义问题。我们最后展示了这种方法如何更普遍地扩展到反可能性。
