  1. Dominic Gregory (2013). Showing, Sensing, and Seeming: Distinctively Sensory Representations and Their Contents. Oxford University Press.
    Certain representations are bound in a special way to our sensory capacities. Many pictures show things as looking certain ways, for instance, while auditory mental images show things as sounding certain ways. What do all those distinctively sensory representations have in common, and what makes them different from representations of other kinds? Dominic Gregory argues that they are alike in having meanings of a certain special type. He employs a host of novel ideas relating to kinds of perceptual states, sensory (...)

  2. Dominic Gregory (2011). Iterated Modalities, Meaning and A Priori Knowledge. Philosophers' Imprint 11 (3).
    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 (...)

  4. Dominic Gregory (2010). Imagery, the Imagination and Experience. 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 (...)

  5. Dominic Gregory (2010). Pictures, Pictorial Contents and Vision. 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 (...)

  6. Dominic Gregory (2010). Visual Imagery: Visual Format or Visual Content? 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 (...)

  8. Dominic Gregory (2006). Functionalism About Possible Worlds. 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 (...)

  9. Dominic Gregory (2005). Keeping Semantics Pure. 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 (...)

  10. Dominic Gregory (2004). Imagining Possibilities. 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.

  11. Dominic Gregory (2001). B is Innocent. Analysis 61 (3):225–229.
    The paper replies to an earlier paper by Yannis Stephanou, who presented an argument purportedly showing the falsity of certain instances of the characteristic axiom of the modal logic B. The paper argues that the B axiom was not to blame for the unsoundness of Stephanou's argument.

  12. Dominic Gregory (2001). Completeness and Decidability Results for Some Propositional Modal Logics Containing “Actually” Operators. 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, (...)
