Possible Worlds

Edited by Dan Marshall (Lingnan University)
About this topic
Summary Possible worlds are complete ways things could be. The metaphysics of possible worlds became a central concern of philosophers in the second half of the twentieth century with the advent of modal logic and possible worlds semantics. Important debates about possible worlds include whether there are any possible worlds, whether possible worlds are abstract or concrete, and whether possible worlds are constructed out other types of entities, such as sets, properties or propositions.
Key works Prominent theories of possible worlds include: the modal realism of Lewis 1986; ersatz theories such as Carnap 1947 , Jeffrey 1965, Hintikka 1969, Plantinga 1974, Stalnaker 1976, Melia 2001, and Sider 2002; and fictionalist theories such as Rosen 1990, and Armstrong 1989.
Introductions Two papers that provide a good introduction to possible worlds are Menzel 2008 and Sider 2003. Two excellent book length introductions to possible worlds are Melia 2003 and Divers 2002, the latter being more advanced than the former.

  1. How to Deal with the Puzzle of Coincident Objects.Ataollah Hashemi - 2017 - Dissertation, University of Alberta
    The grounding problem is related to the puzzle of numerically distinct spatiotemporally coincident objects. Suppose Lumpl –a lump of clay– and Goliath – the statue – are created and later destroyed, simultaneously. They would share all of their physical and spatiotemporal properties and relations. But, Goliath and Lumpl have different modal and sortal properties, which would suggest they are distinct entities, while at the same time entirely co-located. This issue creates a puzzle and raises the question of how two distinct (...)

    In this paper, I discuss a connection between quidditism and the Lewisian principle of recombination. I begin by reconstructing a typical characterisation of a Lewisian principle of recombination, followed by an explanation of quidditism. In the remainder, I argue that a proponent of a Lewisian principle of recombination cannot endorse quidditism without some important modifications of her view.

  4. The False Promises of Logic Textbooks - How Logic Has a Much More Limited Role Than People Usually Think.Matheus Silva - manuscript
    Logic textbooks advertise that they can teach how to spot a valid argument by its logical form alone. They also boast having collections with the most basic valid argumentative forms people of flesh and blood can use in deductive matters. Think about this for a moment. These are bold statements. If they were accurate, philosophers would be in higher demand than software engineers and no one would be able to make contributions to theoretical physics without ever taking a logic class. (...)

  5. Making Sense of Deduction.Matheus Silva - manuscript
    An argument is deductive when the arguer believes the truth of the premises necessitates the truth of the conclusion. A deductive argument is valid when the arguer’s claim is true, i.e., when there are no possible worlds whether the premises are true and the conclusion is false. But in order to evaluate this claim in an accurate manner we need to consider three qualifications that have been repeatedly ignored in the literature, namely, consistency in the attribution of truth values, world (...)

    This article explores Karl Rahner’s conception of the “Liturgy of the World” in light of the theme for the 2019 Annual Convention of the Catholic Theological Society of America, “Another World is Possible: Violence, Resistance and Transformation.” Employing Rahner’s hermeneutics of worship, violence can be conceived as a denial of this cosmic liturgy, transformation as conversion to it, and resistance as the stance opposing the denial. Resistance entails solidarity with all humanity in liturgical participation and in action for social justice. (...)

  7. The Nature of Impossibility.Martin Vacek - 2019 - Bratislava, Slovakia: VEDA.
    Possible-worlds semantics proved itself as a strong tool in analysing the statements of actuality, possibility, contingency and necessity. But impossible phenomena go beyond the expressive power of the apparatus. The proponents of possible-worlds apparatus thus owe us at least three stories. The first one is the story about ontological nature of possible worlds, the second one is the story about the theoretical role such entities play and the third one is the story about the impossible. Modal Realism (MR) provides us (...)

    Pavel Tichy originally published his interesting conception of possible worlds in 1968. Even though he modified it over the following twenty five years, its core remained unchanged. None of his thirty journal papers or books containing the notion of possible worlds was a study in metaphysics, Tichy (and most of his followers) always introduced the notion in the context of other investigations where he applied his Transparent intensional logic either to the semantic analysis of natural language or explications of other (...)

  10. Modal Quantification Without Worlds.Billy Dunaway - 2013 - Oxford Studies in Metaphysics 8.
    This paper is about avoiding commitment to an ontology of possible worlds with two primitives: a hyperintensional connective like ‘in virtue of’, and primitive quantification into predicate position. I argue that these tools (which some believe can be independently motivated) render dispensable the ontology of possible worlds needed by traditional anaylses of modality. They also shed new light on the notion of truth-at-a-world.

    A standard conception of metaphysical modality accepts that Some de re modal claims are true, These should be understood in terms of a possible worlds semantics, and There is trans-world identity. For instance, it seems true that Humphrey could have won the election. In possible worlds speak, we say that there exists a possible world where Humphrey wins the election. Furthermore, had that possibility been actualized instead of this one, Humphrey—our Humphrey, the very same man—would still have existed. Here, I (...)

    This study asserts that W.V.O. Quine’s eliminative philosophical gaze into mereological composition affects inevitably his interpretations of composition theories of ontology. To investigate Quine’s property monism from the account of modal eliminativism, I applied to his solution for the paradoxes of de re modalities’ . Because of its vital role to figure out how dispositions are encountered by Quine, it was significantly noted that the realm of de re modalities doesn’t include contingent and impossible inferences about things. Therefore, for him, (...)

    This note points out a conflict between some common intuitions about metaphysical possibility. On the one hand, it is appealing to deny that there are robust counterfactuals about how various physically impossible substances would interact with the matter that exists at our world. On the other hand, our intuitions about how concepts like MOUNTAIN apply at other metaphysically possible worlds seem to presuppose facts about ‘solidity’ which cash out in terms of these counterfactuals. I consider several simple attempts to resolve (...)

    Considering the importance of possible-world semantics for modal logic and for current debates in the philosophy of modality, a phenomenologist may want to ask whether it makes sense to speak of “possible worlds” in phenomenology. The answer will depend on how "possible worlds" are to be interpreted. As that latter question is the subject of the debate about possibilism and actualism in contemporary modal metaphysics, my aim in this paper is to get a better grip on the former question by (...)

    Many widely divergent accounts of luck have been offered or employed in discussing an equally wide range of philosophical topics. We should, then, expect to find some unified philosophical conception of luck of which moral luck, epistemic luck, and luck egalitarianism are species. One of the attempts to provide such an account is that offered by Duncan Pritchard, which he refers to as the modal account. This view commits us to calling an event lucky when it obtains in this world, (...)

  18. Clauses as Semantic Predicates: Difficulties for Possible-Worlds Semantics.Friederike Moltmann - 2020 - Festschrift for Angelika Kratzer.
    The standard view of clauses embedded under attitude verbs or modal predicates is that they act as terms standing for propositions, a view that faces a range of philosophical and linguistic difficulties. Recently an alternative has been explored according to which embedded clauses act semantically as predicates of content-bearing objects. This paper argues that this approach faces serious problems when it is based on possible worlds-semantics. It outlines a development of the approach in terms of truthmaker theory instead.

  19. Theories in the Light of Contingency and Change: Possible Future Worlds and Well-Grounded Hope as a Supplement to Truth.Frank Ulrich - unknown
    Based on a critical account of the dominant concept of theory, the paper presents an alterna-tive, wider notion of theory. It is motivated by the need to cope with a contingent research subject and the assumption that IS should provide an orientation for managing the digital transfor-mation. Unlike neo-positivistic notions of theory, the proposed conception is not restricted to de-scriptions of the factual, but may be aimed at de-signing possible future worlds. Conceiving of possible future worlds requires overcoming the barriers (...)

    The article investigates the relationship between Leibniz’s and Huygens’ theory of possibility and the principle of conservation of energy. It assumes that their criticisms of Cartesian views concerning those questions as well as their own achievements contributed to the formation of a new metaphysical basis for modern discussions on the freedom of the will. There are especially two problems whose role is crucial in this context, namely the question of God’s knowledge of future conditionals (contingentia futura) and the mind-body distinction.

    Ohad Nachtomy restates the main points of “Plenitude and Compossibility” with admirable fidelity and economy. His proposed revisions, based on the distinction between incomplete and complete substances and on the mind-relativity of relations, are intriguing additions to his earlier paper in Studia Leibnitiana and deserve careful consideration. Some brief remarks on the context of the problem, will, I hope, help to set the stage for the assessment of our various views.
