79Hybrid Identities and Just Being YourselfInquiry: An Interdisciplinary Journal of Philosophy 57 (4): 455-465. 2014.This paper points out a tension between Agustín Rayo's criteria for singulartermhood and his explicit views on the status of Hybrid Identities, that is, identity statements that use singular terms from two different Systems of Representation, such as "7=Julius Caesar" or more suggestively "I am b" where "b" is a singular term referring to my brain. It argues that non-trivial Hybrid Identities are common and important in philosophy and elsewhere, and it suggests a friendly alternative that invol…Read more

366The Justification of the Basic Laws of LogicJournal of Philosophical Logic 44 (6): 793-803. 2015.Take a correct sequent of formal logic, perhaps a simple logical truth, like the law of excluded middle, or something with premises, like disjunctive syllogism, but basically a claim of the form \.Γ can be empty. If you don’t like my examples, feel free to choose your own, everything I have to say should apply to those as well. Such a sequent attributes the properties of logical truth or logical consequence to a schematic sentence or argument. This paper aims to answer the question of how belief…Read more

51Language, Locations and PresuppositionLinguistic and Philosophical Investigations 9 194-205. 2010.Could it ever be right to say that a language---as opposed to a speaker of the language---makes, or presupposes or somehow commits itself to certain claims? Such as that certain kinds of objects exist, or that things are a certain way? It can be tempting to think not, to think that languages are just the neutral media through which speakers make claims. Yet certain, surprisingly diverse, phenomena---analyticity, racial epithets, object-involving direct reference, arithmetic, and semantic paradox…Read more

99Review: Warren Goldfarb’s Deductive Logic (review)Australasian Journal of Logic 3 63-66. 2005.Deductive Logic is an introductory textbook in formal logic. The book is divided into four parts covering (i) truth-functional logic, (ii) monadic quantifi- cation, (iii) polyadic quantification and (iv) names and identity, and there are exercises for all these topics at the end of the book. In the truth-functional logic part, the reader learns to produce paraphrases of English statements and arguments in logical notation (this subsection is called “analysis”), then about the semantic properties…Read more

158Indexicals, context-sensitivity and the failure of implicationSynthese 183 (2). 2011.This paper investigates, formulates and proves an indexical barrier theorem, according to which sets of non-indexical sentences do not entail (except under specified special circumstances) indexical sentences. It surveys the usual difficulties for this kind of project, as well some that are specific to the case of indexicals, and adapts the strategy of Restall and Russell's "Barriers to Implication" to overcome these. At the end of the paper a reverse barrier theorem is also proved, according to…Read more
