El dialeteísmo es la posición que afirma que hay contradicciones verdaderas. Este artículo versará sobre esa posición. En la primera sección, mencionaré los principales aportes que, en mi perspectiva, el dialeteísmo ha hecho a la lógica filosófica. En la segunda sección, analizaré el principal problema del dialeteísmo. En la tercera sección, mostraré que los argumentos a favor del dialeteísmo no llegan a establecer la verdad de esta posición. Finalmente, explicaré cuál es el tipo de paraconsistencia que considero adecuada y la (...) compararé con la posición dialeteísta. Dialetheism is the position which claims that there are true contradictions. This paper deals with this position. In the first section, I will mention the main contributions that, in my perspective, dialetheism has made to philosophical logic. In the second section, I will analyze the main problem of dialetheism. In the third section, I will show that the arguments in favor of dialetheism are not conclusive. Finally, I will explain which kind of paraconsistency I consider adequate, and I will compare it with the dialetheist position. (shrink)

A reply to two responses to an earlier paper, "A Liar Paradox".

What is commonly referred to as the Adoption Problem is a challenge to the idea that the principles of logic can be rationally revised. The argument is based on a reconstruction of unpublished work by Saul Kripke. As the reconstruction has it, Kripke extends the scope of Willard van Orman Quine's regress argument against conventionalism to the possibility of adopting new logical principles. In this paper we want to discuss the scope of this challenge. Are all revisions of logic subject (...) to the Adoption Problem? If not, are there significant cases of logical revision that are subject to the Adoption Problem? We will argue that both questions should be answered negatively. (shrink)

This monograph examines truth in fiction by applying the techniques of a naturalized logic of human cognitive practices. The author structures his project around two focal questions. What would it take to write a book about truth in literary discourse with reasonable promise of getting it right? What would it take to write a book about truth in fiction as true to the facts of lived literary experience as objectivity allows? It is argued that the most semantically distinctive feature of (...) the sentences of fiction is that they are unambiguously true and false together. It is true that Sherlock Holmes lived at 221B Baker Street and also concurrently false that he did. A second distinctive feature of fiction is that the reader at large knows of this inconsistency and isn't in the least cognitively molested by it. Why, it is asked, would this be so? What would explain it? Two answers are developed. According to the no-contradiction thesis, the semantically tangled sentences of fiction are indeed logically inconsistent but not logically contradictory. According to the no-bother thesis, if the inconsistencies of fiction were contradictory, a properly contrived logic for the rational management of inconsistency would explain why readers at large are not thrown off cognitive stride by their embrace of those contradictions. As developed here, the account of fiction suggests the presence of an underlying three - or four-valued dialethic logic. The author shows this to be a mistaken impression. There are only two truth-values in his logic of fiction. The naturalized logic of Truth in Fiction jettisons some of the standard assumptions and analytical tools of contemporary philosophy, chiefly because the neurotypical linguistic and cognitive behaviour of humanity at large is at variance with them. Using the resources of a causal response epistemology in tandem with the naturalized logic, the theory produced here is data-driven, empirically sensitive, and open to a circumspect collaboration with the empirical sciences of language and cognition.
