The overgeneration argument attempts to show that accepting second-order validity as a sound formal counterpart of logical truth has the unacceptable consequence that the Continuum Hypothesis is either a logical truth or a logical falsehood. The argument was presented and vigorously defended in John Etchemendy’s The Concept of Logical Consequence and it has many proponents to this day. Yet it is nothing but a seductive fallacy. I demonstrate this by considering five versions of the argument; as I show, each is (...) either unsound or lacks a troubling conclusion. (shrink)

In this reply I defend Kripke’s creationist thesis for mythical objects against Jeffrey Goodman’s counter-argument to the thesis, 35–40, 2014). I argue that Goodman has mistaken the basis for when mythical abstracta are created. Contrary to Goodman I show that, as well as how, Kripke’s theory consistently retains the analogy between creation of mythical objects and creation of fictional objects, while also explaining in what way they differ.

Many who think that some abstracta are artefacts are fictional creationists, asserting that fictional characters are brought about by our activities. Kripke (1973), Salmon (1998, 2002), and Braun (2005) further embrace mythical creationism, claiming that certain entities that figure in false theories, such as phlogiston or Vulcan, are likewise abstracta produced by our intentional activities. I here argue that one may not reasonably take the metaphysical route travelled by the mythical creationist. Even if one holds that fictional characters are artefact (...) one ought not further hold that mythical objects are, too. (shrink)

En los últimos años, el interés por la semántica de términos ficticios ha crecido considerablemente en el marco de la tradición analítica. De forma general, es posible distinguir dos grandes tipos de propuestas semánticas: las propuestas ontológicamente comprometidas con entidades ficticias y las que evitan dicho compromiso . Entre estas últimas, se destaca la propuesta inscripcionalista de Nelson Goodman y Catherine Elgin, que constituye el eje de análisis del presente artículo. Su objetivo principal es mostrar algunas de las ventajas de (...) la propuesta inscripcionalista frente a las propuestas realistas. En la segunda sección, analizo algunas de las dificultades que conllevan las propuestas realistas y luego muestro que estas no tienen lugar en la propuesta de Goodman y Elgin. En la tercera sección, presento la propuesta inscripcionalista, centrándome en su ampliación, la noción de referencia y sus diversas modalidades, y también analizo una serie de enunciados problemáticos utilizando los modos referenciales anteriormente presentados.

In (1959), Carnap famously attacked Heidegger for having constructed an insane metaphysics based on a misconception of both the logical form and the semantics of ordinary language. In what follows, it will be argued that, once one appropriately (i.e., in a Russellian fashion) reads Heidegger’s famous sentence that should paradigmatically exemplify such a misconception, i.e., “the nothing nothings”, there is nothing either logically or semantically wrong with it. The real controversy as to how that sentence has to be evaluated—not as (...) to its meaning but as to its truth—lies at the metaphysico- ontological level. For in order for the sentence to be true one has to endorse an ontology of impossibilia and Leibniz’s principle of the identity of indiscernibles. (shrink)

Artifactualism about fictional characters, positing Harry Potter as an abstract artifact created by J. K. Rowling, has been criticized on the grounds that the idea of creating such objects is mysterious and problematic. In the light of such qualms, it is worth homing in on an argument in favor of artifactualism, showing that it is the best way to include the likes of Harry Potter in our ontology precisely because it incorporates authorial creation. To that end, I will be exploring (...) Kripke’s fleeting remarks in the Addenda to his “Naming and Necessity” lectures about expressions like ‘unicorn’ and ‘Harry Potter’. Elsewhere, Kripke motivates artifactualism by suggesting that incorporating authorial creation (as artifactualism does) is a move that is intuitive and natural; but beyond this, he doesn’t provide any arguments in favor of such a move. My purpose in this paper is to construct such an argument based on considerations about Kripke’s general view about proper names, in particular, his seminal causal-historical chain account of reference determination, and its consequences for fictional names as well as nonfictional names without bearers such as ‘Vulcan’.

In several papers, Petr Koťátko defends an “ontologically modest account of fictional characters”. Consider a position (which I have been defending) that is anything but ontologically restrained: positing fictional characters like Andrei Bolkonsky in War and Peace as abstract artifacts. I will argue, first, that such a position turns out to offer a nice fit with Petr Koťátko’s proposal about narrative fiction, one that fares better than an alternative pretense-based theory that doesn’t posit Bolkonsky as existing in any sense. Second, (...) I will explore a recent challenge by Jeffrey Goodman—which I will call the inadvertent creation challenge—that is originally posed for those who hold that fictional characters and mythical objects alike are abstract artifacts. The crux of the challenge is this: if we think that astronomers like Le Verrier, in mistakenly hypothesizing the planet Vulcan, inadvertently create an abstract artifact, then the inadvertent creation” element turns out to be inescapable yet theoretically unattractive. Third, based on considerations about actually existing concrete objects being featured in fictional works (as Napoleon is in War and Peace), I argue that regardless of where one stands on mythical objects, admitting fictional characters as abstract artifacts is enough to give rise to the inadvertent creation challenge; yet this very set of considerations serves to undermine the challenge, indicating that inadvertent creation is not nearly as worrisome after all as Goodman is suggesting. Taking fictional characters (and mythical objects) to be abstract artifacts therefore remains a viable option. -/- . (shrink)
