  1. Counterfactual Reasoning and Knowledge of Possibilities.Dominic Gregory - 2017 - Philosophical Studies 174 (4):821-835.
    Williamson has argued against scepticism concerning our metaphysically modal knowledge, by arguing that standard patterns of suppositional reasoning to counterfactual conclusions provide reliable sources of correct ascriptions of possibility and necessity. The paper argues that, while Williamson’s claims relating to necessity may well be right, he has not provided adequate reasons for thinking that the familiar modes of counterfactual reasoning to which he points generalise to provide a decent route to ascriptions of possibility. The paper also explores another path to (...)

  2. Imagining Possibilities.Dominic Gregory - 2004 - Philosophy and Phenomenological Research 69 (2):327–348.
    Kripkean examples of necessary a posteriori truths clearly provide a challenge to attempts to connect facts about possibility to facts about what people can conceive. The paper argues for a general principle connecting imaginability under certain special circumstances to possibility; it also discusses some of the issues raised by the resulting position.

  3. Imagery and Possibility.Dominic Gregory - 2020 - Noûs 54 (4):755-773.
    We often ascribe possibility to the scenes that are displayed by mental or nonmental sensory images. The paper presents a novel argument for thinking that we are prima facie justified in ascribing metaphysical possibility to what is displayed by suitable visual images, and it argues that many of our imagery‐based ascriptions of metaphysical possibility are therefore prima facie justified. Some potential objections to the arguments are discussed, and some potential extensions of them, to cover nonvisual forms of imagery and nonmetaphysical (...)

  4. Imagery, the Imagination and Experience.Dominic Gregory - 2010 - Philosophical Quarterly 60 (241):735-753.
    Visualizings, the simplest imaginings which employ visual imagery, have certain characteristic features; they are perspectival, for instance. Also, it seems that some but not all of our visualizings are imaginings of seeings. But it has been forcefully argued, for example by M.G.F. Martin and Christopher Peacocke, that all visualizings are imaginings of visual sensations. I block these arguments by providing an account of visualizings which allows for their perspectival nature and other features they typically have, but which also explains how (...)

    Showing, Sensing, and Seeming: Distinctively Sensory Representations and Their Contents.Dominic Gregory - 2013 - Oxford University Press UK.
    Certain representations are bound in special ways to our sensory capacities. What do these representations have in common, and what makes them different from representations of other kinds? Dominic Gregory employs novel ideas on perceptual states and sensory perspectives to explain the special nature of distinctively sensory representations.

    Completeness and Decidability Results for Some Propositional Modal Logics Containing “Actually” Operators.Dominic Gregory - 2001 - Journal of Philosophical Logic 30 (1):57-78.
    The addition of "actually" operators to modal languages allows us to capture important inferential behaviours which cannot be adequately captured in logics formulated in simpler languages. Previous work on modal logics containing "actually" operators has concentrated entirely upon extensions of KT5 and has employed a particular modeltheoretic treatment of them. This paper proves completeness and decidability results for a range of normal and nonnormal but quasi-normal propositional modal logics containing "actually" operators, the weakest of which are conservative extensions of K, (...)

    Imagining Possibilities.Dominic Gregory - 2004 - Philosophy and Phenomenological Research 69 (2):327-348.
    This paper argues that the imaginability of propositions of a certain kind under certain special circumstances implies their possibility. It then attempts to use that conclusion in doing some modal epistemology. In particular, the paper argues that the conclusion justifies some ascriptions of possibility and that it promises to justify some ascriptions of impossibility.

    Conceivability and Apparent Possibility.Dominic Gregory - 2009 - In Bob Hale & Aviv Hoffmann (eds.), Modality: Metaphysics, Logic, and Epistemology. Oxford University Press.
    Why do we tend to ascribe possibility to what we can imagine? One strategy for answering that question involves the thought that, just as sensory episodes often involve its seeming to us as though the world is certain ways, so imaginings involve its seeming to us that what we have imagined is possible. This chapter argues that while some imaginings do feature appearances of possibility, very many others do not; and it explores the broader relevance of its conclusions for modal (...)

  11. Iterated Modalities, Meaning and A Priori Knowledge.Dominic Gregory - 2011 - Philosophers' Imprint 11.
    Recent work on the philosophy of modality has tended to pass over questions about iterated modalities in favour of constructing ambitious metaphysical theories of possibility and necessity, despite the central importance of iterated modalities to modal logic. Yet there are numerous unresolved but fundamental issues involving iterated modalities: Chandler and Salmon have provided forceful arguments against the widespread assumption that all necessary truths are necessarily necessary, for example. The current paper examines a range of ways in which one might seek (...)

    Visual Content, Expectations, and the Outside World.Dominic Gregory - 2015 - Proceedings of the Aristotelian Society 115 (2pt2):109-130.
    Some philosophers—for example, Husserl, Alva Noë and Susanna Siegel—have claimed that the contents of visual sensations standardly include references to the later visual episodes that one would have under certain conditions. The current paper claims that there are no good reasons for accepting that view. Instead, it is argued that the conscious phenomena which have been cited as manifesting the presence within visual contents of references to ways that things would look in the course of later visual sensations are better (...)

  13. Functionalism About Possible Worlds.Dominic Gregory - 2006 - Australasian Journal of Philosophy 84 (1):95 – 115.
    Various writers have proposed that the notion of a possible world is a functional concept, yet very little has been done to develop that proposal. This paper explores a particular functionalist account of possible worlds, according to which pluralities of possible worlds are the bases for structures which provide occupants for the roles which analyse our ordinary modal concepts. It argues that the resulting position meets some of the stringent constraints which philosophers have placed upon accounts of possible worlds, while (...)

  14. Pictures, Pictorial Contents and Vision.Dominic Gregory - 2010 - British Journal of Aesthetics 50 (1):15-32.
    Certain simple thoughts about pictures suggest that the contents of pictures are closely bound to vision. But how far can the striking features of depiction be accounted for merely in terms of the especially visual contents which belong to pictures, without considering, for example, any issues concerning the nature of the visual experiences with which pictures provide us? This article addresses that question by providing an account of the distinctively visual contents belonging to pictures, and by using that account to (...)

  15. Visual Imagery: Visual Format or Visual Content?Dominic Gregory - 2010 - Mind and Language 25 (4):394-417.
    It is clear that visual imagery is somehow significantly visual. Some theorists, like Kosslyn, claim that the visual nature of visualisations derives from features of the neural processes which underlie those episodes. Pylyshyn claims, however, that it may merely reflect special features of the contents which we grasp when we visualise things. This paper discusses and rejects Pylyshyn's own attempts to identify the respects in which the contents of visualisations are notably visual. It then offers a novel and very different (...)

    Keeping Semantics Pure.Dominic Gregory - 2005 - Noûs 39 (3):505–528.
    There are numerous contexts in which philosophers and others use model-theoretic methods in assessing the validity of ordinary arguments; consider, for example, the use of models built upon 'possible worlds' in examinations of modal arguments. But the relevant uses of model-theoretic techniques may seem to assume controversial semantic or metaphysical accounts of ordinary concepts. So, numerous philosophers have suggested that standard uses of model-theoretic methods in assessing the validity of modal arguments commit one to accepting that modal claims are to (...)

    Pictures, Propositions, and Predicates.Dominic Gregory - 2020 - American Philosophical Quarterly 57 (2):155-170.
    Do representational pictures have propositional contents? The current paper argues that the characteristic contents of pictures are predicative rather than propositional: pictures characterise things as looking certain ways, and they thereby express properties of visual perspectives. The paper argues that the characteristic predicative contents of pictures are nonetheless able to feature in fully-fledged propositional contents once they are combined with contents of other suitable sorts. Various facts about communicative uses of pictures are then explained. The paper concludes by considering the (...)

    Visual Expectations and Visual Imagination.Dominic Gregory - 2017 - Philosophical Perspectives 31 (1):187-206.
    (Open Access article, freely available to download from publisher's site.) Our visual experiences of objects as located in external space, and as having definite three-dimensional shapes, are closely linked to our implicit expectations about what things will look like from alternative viewpoints. What sorts of contents do these expectations involve? One standard answer is that they relate to what things will look like to us upon changing our positions. And what sorts of mental representations do the expectations call upon? A (...)
