    Mere possibilities - Bolzano's account of non-actual objects
    Journal of the History of Philosophy 45 (4): 525-550. 2007.
    The paper is a detailed reconstruction of Bernard Bolzano’s account of merely possible objects. According to Bolzano, there are some objects which are merely possible. They are neither denizens of space and time nor members of the causal order, but they could have been so. Examples are merely possible persons, mountains etc., objects which are neither actual nor persons or mountains, but which could have been both. Bolzano’s views are contrasted with the theory of Alexius Meinong, and it is show…Read more

    Inexpressible properties and Grelling’s antinomy
    Philosophical Studies 148 (3). 2010.
    The paper discusses whether there are strictly inexpressible properties. Three main points are argued for: (i) Two different senses of ‘predicate t expresses property p ’ should be distinguished. (ii) The property of being a predicate that does not apply to itself is inexpressible in one of the senses of ‘express’, but not in the other. (iii) Since the said property is related to Grelling’s Antinomy, it is further argued that the antinomy does not imply the non-existence of that property.

    Are all canonical property designators (i.e. nominalizations of predicative phrases) rigid? Dan López de Sa recently criticized the arguments I gave for an affirmative answer to that question. The current article rebuts López de Sa's objections.

    In defence of a logic for ‘because’
    Journal of Applied Non-Classical Logics 26 (2): 160-171. 2016.
    The present author developed a calculus for the logic of ‘because’. In a recent paper in this journal, it has been claimed that the central inference rules for the logic are invalid and that the intuition upon which the rules are based is not accounted for. This note criticises these arguments and presents an independent argument in favour of the rules used in the logic.

    Grounding and dependence
    Synthese 197 (1): 95-124. 2020.
    The paper deals with the notions of grounding and of existential dependence. It is shown that cases of existential dependence seem to be systematically correlated to cases of grounding and hence the question is raised what sort of tie might hold the two notions together so as to account for the observed correlation. The paper focusses on three possible ties between grounding and existential dependence: identity, definition, and grounding. A case for the definitional tie is made.

    In defence of fictional realism
    Philosophical Quarterly 59 (234): 138-149. 2009.
    Fictional realism, i.e., the view that because fictions exist, fictional characters exist as well, has recently been accused of leading to inconsistency generated by phenomena of indeterminacy and inconsistency in fiction. We examine in detail four arguments against fictional realism, and present a version of fictional realism which can withstand those arguments.

    The article is a critical examination of Joshua Hoffman’s and Gary Rosenkrantz’ approach to the traditional category of individual substance. On several places they offered an analysis of the concept of a substance in terms of some highly sophisticated notion of generic independence. Though ingenious, and even though it might be extensionally adequate, their account cannot provide an informative analysis of the concept in question, because it exhibits a peculiar kind of circularity. It is shown …Read more

    Bad Examples?
    American Philosophical Quarterly 47 (3): 279-286. 2010.
    By fictional realism let us understand the doctrine that there are fictional entities, in the same sense of "there are" in which -- philosophical worries set aside -- there are people, planets, and prime numbers. The standard argument for fictional realism runs as follows. Consider the following two sentences: Some characters in nineteenth-century novels are presented with a greater wealth of physical detail than are some characters in twentieth-century novels. Some fictional detectives are more…Read more

    Expressivism concerning epistemic modals
    Philosophical Quarterly 60 (240): 601-615. 2010.
    I develop a new argument for an expressivist account of epistemic modals, which starts from a puzzle about epistemic modals which Seth Yalcin recently presented. I reject Yalcin's own solution to the puzzle, and give a better explanation based on expressivism concerning epistemic modals. I also address two alleged problems for expressivism: do embeddings of epistemic modals pose a serious threat to expressivism, and how can expressivism account for disagreements about statements containing epist…Read more

    Im folgenden Diskussionsbeitrag werden zunächst starke Spannungen innerhalb von Bolzanos Ausführungen zum Substanzbegriff aufgezeigt. Sodann wird eine kürzlich vorgeschlagene Bolzano-Interpretation besprochen, die geeignet sein soll, besagte Spannungen auszuräumen. Doch der Vorschlag bleibt unbefriedigend; daher wird im Anschluss eine alternative Interpretation ausgeführt und verteidigt.

    Das Meisterargument in Platons Euthyphron
    History of Philosophy & Logical Analysis 18 (1): 227-254. 2015.
    In Plato’s Euthyphro, Euthyphro proposes to analyse the pious as that which is beloved of the gods. In the most widely discussed argument of the dialogue, Socrates tries to show that Euthyphro’s analysis fails. The argument crucially involves an ingenious use of the explanatory connective ‘because’. This paper presents a detailed reconstruction and defence of the argument. It starts with a rigorous analysis of its logical form, explains and justifies its premises, and closes with a defence of th…Read more

    Bolzano on Causation and Grounding
    Journal of the History of Philosophy 52 (2): 309-337. 2014.
    This Paper is an Exploration of Bolzano’s views on causation, which have not been thoroughly examined yet. The paper reconstructs Bolzano’s position, with a focus on his analysis of the concept of causation, on its ontological presuppositions, and on how he relates causation to his theory of grounding.1 A comparison with standard positions from the contemporary debate on causation will prove his views to be quite original. Moreover, they are a valuable addition to the more recent debate on metap…Read more

    Bernard Bolzano développe une théorie exhaustive et très élaborée des propositions comme entités structurées et composées de concepts. L’une de ses thèses principales consiste à dire que toutes les propositions ont en commun la même structure : « A – a – b ». Cet article examine le rôle que jouent les propriétés eu égard à cette thèse. Lorsque les propriétés figurent dans les théories sémantiques standards, elles sont généralement conçues comme des entités partageables, en d’autres mots, comme d…Read more

    Canonical property designators
    American Philosophical Quarterly 43 (2). 2006.
    The article scrutinises the semantics of canonical property designators of the forms ‘the property of being F’ and ‘F-ness’. First it is argued that, as their form suggests, the former are definite definitions, albeit of a special sort. Secondly, the prima facie plausible classification of the latter as proper names (which is often met in philosophical writings) is rejected. The semantics of such terms is developed and it is shown how its proper understanding yields important consequences about …Read more

    Many friends of the category of particularised qualities subscribe to the view that particularised qualities have a unique bearer in which they inhere; no such quality then can inhere in two different entities. But it seems that this idea is flawed, for there are apparent counterexamples. An apple’s redness is identical with the redness of its skin, though the apple is distinct from its skin. So it seems that a principle of beareruniqueness has to be modified, maybe by excluding certain unwanted…Read more
