Intuitionism’s disagreement with classical logic is standardly based on its specific understanding of truth. But different intuitionists have actually explicated the notion of truth in fundamentally different ways. These are considered systematically and separately, and evaluated critically. It is argued that each account faces difficult problems. They all either have implausible consequences or are viciously circular.

Uno de los principales aportes de Michael Dummett a la filosofía contemporánea fue la idea de que ciertas disputas tradicionales de la metafísica podían ser replanteadas a través de una caracterización semántica del realismo y el antirrealismo. Apoyándose en esta caracterización, Dummett propuso una aproximación ascendente a esas disputas. Dicha aproximación buscaba resolver los desacuerdos metafísicos entre realistas y antirrealistas mediante la formulación de teorías semánticas para ciertos conjuntos de enunciados. En este artículo argumentamos que la caracterización de Dummett no (...) captura las disputas metafísicas tradicionales y que, como consecuencia de ello, dicha caracterización no constituye un buen sustento para la aproximación ascendente.

Michael Dummett offered a semantic characterisation of a variety of realism-antirealism debates. This approach has fallen out of fashion. This has been to the detriment of metaphysics. This paper offers an accurate characterisation of Dummett’s view, often lacking in the literature, and then defends it against a range of attacks (from Devitt, Miller and Williamson). This understanding of realism debates is resilient, and if we take it seriously the philosophical terrain looks importantly different. In particular, the philosophy of language has (...) a foundational role with respect to metaphysics. (shrink)

Un des enjeux les plus importants pour la compréhension des Recherches Logiques et pour l’unité de la pensée d’Edmund Husserl réside dans la question du caractère idéaliste ou réaliste du projet philosophique de l’ouvrage. Dans cet article, je me penche sur cette question et établis, à partir d’un commentaire de passages clefs du texte, que la philosophie du jeune Husserl est bel et bien réaliste, à la fois en ce qui concerne le réal et l’idéal. Je montre aussi ce qu’il (...) y a d’erroné dans deux autres lectures de Husserl sur cette question, à savoir la lecture idéaliste et celle voulant qu’il adhère à une forme de neutralité métaphysique.One of the most important issues for the understanding of the Logical Investigations and for the unity of Edmund Husserl’s thought consists in the question of the realistic or idealistic character of its philosophical project. In this paper, I address this issue and establish on the basis of a close commentary of the text that the philosophy of the young Husserl is realistic both regarding the realm of the real and the one of the ideal. I also show what is wrong with two other readings of Husserl on this question : the idealistic and the neutral point of view readings. (shrink)

Negation, denial and falsity lie at the heart of debates about logic. We set out the classical account of the relationship between negation and denial, owing to Frege and Geach. We then challenge this on the basis that it does not permit an adequate account of falsity. A dialetheic alternative is minuted and criticised before a novel rejectivist account is proposed according to which falsity is the aim of the speech‐act of denial, whilst negation embeds deniability into assertoric contexts.
