  • Proxy “Actualism”.Karen Bennett - 2006 - Philosophical Studies 129 (2):263-294.
    Bernard Linsky and Edward Zalta have recently proposed a new form of actualism. I characterize the general form of their view and the motivations behind it. I argue that it is not quite new – it bears interesting similarities to Alvin Plantinga’s view – and that it definitely isn’t actualist.

  • Recent Work: Modality without Possible Worlds.Barbara Vetter - 2011 - Analysis 71 (4):742-754.
    This paper surveys recent "new actualist" approaches to modality that do without possible worlds and locate modality squarely in the actual world. New actualist theories include essentialism and dispositionalism about modality, each of which can come in different varieties. The commonalities and differences between these views, as well as their shared motivations, are layed out.

  • Abstract Objects: An Introduction to Axiomatic Metaphysics.Edward N. Zalta - 1983 - Dordrecht, Netherland: D. Reidel.
    In this book, Zalta attempts to lay the axiomatic foundations of metaphysics by developing and applying a (formal) theory of abstract objects. The cornerstones include a principle which presents precise conditions under which there are abstract objects and a principle which says when apparently distinct such objects are in fact identical. The principles are constructed out of a basic set of primitive notions, which are identified at the end of the Introduction, just before the theorizing begins. The main reason for (...)

  • (1 other version)Assertion revisited: On the interpretation of two-dimensional modal semantics.Robert C. Stalnaker - 2004 - Philosophical Studies 118 (1-2):299-322.
    This paper concerns the applications of two-dimensional modal semantics to the explanation of the contents of speech and thought. Different interpretations and applications of the apparatus are contrasted. First, it is argued that David Kaplan's two-dimensional semantics for indexical expressions is different from the use that I made of a formally similar framework to represent the role of contingent information in the determination of what is said. But the two applications are complementary rather than conflicting. Second, my interpretation of the (...)

    Already in 1863, Jules Verne knew about Caselli's "pantelegraphy," which was what he described as a "photographic telegraphy, invented during the last century by Professor Giovanni Caselli of Florence."1 Following the mistaken belief that facsimile machines could not been invented until well after the nineteenth century, and wrongly assuming that Caselli was a fictional inventor, merely a figment of Verne's most productive fertile imagination (as such imaginative elements characterize his latter writings), some of Verne's readers mistakenly ascribed to him the (...)

  • The things that aren’t actually there.Richard Woodward - 2011 - Philosophical Studies 152 (2):155-166.
    The standard Kripkean semantic theories for quantified modal logic allow the individuals that exist at other worlds to vary from those that exist at the actual world. This causes a problem for those who deny the existence of non-actual individuals. I focus on two prominent strategies for solving this problem, due respectively to Bernard Linsky and Edward Zalta (who identify the possible individuals with the actual individuals) and Alvin Plantinga (who identifies the possible individuals with the individual essences). I argue, (...)

  • Modal truthmakers and two varieties of actualism.Gabriele Contessa - 2010 - Synthese 174 (3):341 - 353.
    In this paper, I distinguish between two varieties of actualism—hardcore actualism and softcore actualism—and I critically discuss Ross Cameron’s recent arguments for preferring a softcore actualist account of the truthmakers for modal truths over hardcore actualist ones. In the process, I offer some arguments for preferring the hardcore actualist account of modal truthmakers over the softcore actualist one.

  • The epistemological status of computer-assisted proofs.Mark McEvoy - 2008 - Philosophia Mathematica 16 (3):374-387.
    Several high-profile mathematical problems have been solved in recent decades by computer-assisted proofs. Some philosophers have argued that such proofs are a posteriori on the grounds that some such proofs are unsurveyable; that our warrant for accepting these proofs involves empirical claims about the reliability of computers; that there might be errors in the computer or program executing the proof; and that appeal to computer introduces into a proof an experimental element. I argue that none of these arguments withstands scrutiny, (...)

  • Two axes of actualism.Karen Bennett - 2005 - Philosophical Review 114 (3):297-326.
    Actualists routinely characterize their view by means of the slogan, “Everything is actual.” They say that there aren’t any things that exist but do not actually exist—there aren’t any “mere possibilia.” If there are any things that deserve the label ‘possible world’, they are just actually existing entities of some kind—maximally consistent sets of sentences, or maximal uninstantiated properties, or maximal possible states of affairs, or something along those lines. Possibilists, in contrast, do think that there are mere possibilia, that (...)

  • Sketch for a Systematic Metaphysics.D. M. Armstrong - 2010 - Oxford, UK: Oxford University Press UK.
    In his last book, David Armstrong sets out his metaphysical system in a set of concise and lively chapters each dealing with one aspect of the world. He begins with the assumption that all that exists is the physical world of space-time. On this foundation he constructs a coherent metaphysical scheme that gives plausible answers to many of the great problems of metaphysics. He gives accounts of properties, relations, and particulars; laws of nature; modality; abstract objects such as numbers; and (...)

    This book discovers areas and themes, especially in philosophical psychology, for novel observations and investigations, the diversity of which is systematically unified within the frame of the author¿s original metaphysics, panenmentalism. The book demonstrates how by means of truthful fictions we may detect meaningful possibilities as well as their necessary relationships that otherwise could not be discovered.

  • Shechtman’s three question marks: possibility, impossibility, and quasicrystals. [REVIEW]Amihud Gilead - 2012 - Foundations of Chemistry 15 (2):209-224.
    The revolutionary discovery of actual quasicrystals, thanks to Dan Shechtman’s stamina, is a golden opportunity to analyze once again the role that pure (“theoretical”) possibilities and saving them plays in scientific progress. Some theoreticians, primarily Alan Mackay, contributed to saving pure possibilities of quasicrystalline structures and to opening materials science for them. My analysis rests upon an original modal metaphysics—panenmentalism—which I introduced and have been developing since 1999, quite independently of any familiarity with modern crystallography, and which deals with saving (...)
