20Evaluating Etchemendy's Critiques of Tarski’s Analysis of Logical ConsequencePhilosophical Investigations 16 (38): 505-532. 2022.According to Tarski's model-theoretic analysis of logical consequence, the sentence X is a logical consequence of a set of sentences Γ if and only if any model for Γ is also a model for X. Etchemendy, however, does not accept the analysis and critiques it. According to Etchemendy, Tarski’s analysis 1- involves a conceptual mistake: confusing the symptoms of logical consequence with their cause; 2- cannot properly explain the necessity of logical consequence; 3- faces the problem of overgeneratio…Read more

34Semantic Externalism, and Justified Belief about the External WorldPhilosophical Readings 12 (3). 2020.Philosophical skepticism about the external world seeks to call into question our knowledge of the external world. Some kinds of philosophical skepticism employ skeptical hypotheses to prove that we cannot know anything about the external world. Putnam tried to refute this kind of skepticism by adopting semantic externalism; but, as is now generally accepted, Putnam’s argument is epistemically circular. Brueckner proposes some new, “simple” arguments that in his view are not circular. In this pa…Read more

37The Collapse Argument ReconsideredLogos and Episteme 11 (4): 413-427. 2020.According to Beall and Restall’s logical pluralism, classical logic, relevant logic, and intuitionistic logic are all correct. On this version of logical pluralism, logic is considered to be normative, in the sense that someone who accepts the truth of the premises of a valid argument, is bound to accept the conclusion. So-called collapse arguments are designed to show the incompatibility of the simultaneous acceptance of logical pluralism and the normativity of logic. Caret, however, by proposi…Read more
