    A logic for 'because'
    Review of Symbolic Logic 4 (3): 445-465. 2011.
    In spite of its significance for everyday and philosophical discourse, the explanatory connective has not received much treatment in the philosophy of logic. The present paper develops a logic for based on systematic connections between and the truth-functional connectives

    Truth-Making without Truth-Makers
    Synthese 152 (1): 21-46. 2006.
    The article is primarily concerned with the notion of a truth-maker. An explication for this notion is offered, which relates it to other notions of making something such-and-such. In particular, it is shown that the notion of a truth-maker is a close relative of a concept employed by van Inwagen in the formulation of his Consequence Argument. This circumstance helps understanding the general mechanisms of the concepts involved. Thus, a schematic explication of a whole battery of related notions…Read more

    A Certain Kind of Trinity: Dependence, Substance, Explanation
    Philosophical Studies 129 (2): 393-419. 2006.
    The main contribution of this paper is a novel account of ontological dependence. While dependence is often explained in terms of modality and existence, there are relations of dependence that slip through the mesh of such an account. Starting from an idea proposed by Jonathan Lowe, the article develops an account of ontological dependence based on a notion of explanation; on its basis, certain relations of dependence can be established that cannot be accounted by the modal-existential account. …Read more

    A Puzzle About 'because'
    Logique Et Analyse 53. 2010.
    The essay is a partial investigation into the semantics of the explanatory connective ‘because’. After three independently plausible assumptions about ‘because’ are presented in some detail, it is shown how their interaction generates a puzzle about ‘because’, once they are combined with a common view on conceptual analysis. Four possible solutions to the puzzle are considered

    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.

    What might be and what might have been
    with Moritz Schulz and Alexander Steinberg
    In S.-J. Conrad & S. Imhof (eds.), Strawson - Concept and Object, Ontos. 2010.
    The article is an extended comment on Strawson’s neglected paper ‘Maybes and Might Have Beens’, in which he suggests that both statements about what may be the case and statements about what might have been the case can be understood epistemically. We argue that Strawson is right about the first sort of statements but wrong about the second. Finally, we discuss some of Strawson’s claims which are related to positions of Origin Essentialism.

    Metaphysical grounding: understanding the structure of reality (edited book)
    Cambridge University Press. 2012.
    Some of the most eminent and enduring philosophical questions concern matters of priority: what is prior to what? What 'grounds' what? Is, for instance, matter prior to mind? Recently, a vivid debate has arisen about how such questions have to be understood. Can the relevant notion or notions of priority be spelled out? And how do they relate to other metaphysical notions, such as modality, truth-making or essence? This volume of new essays, by leading figures in contemporary metaphysics, is the…Read more

    Without Reason?
    Pacific Philosophical Quarterly 97 (4): 523-541. 2015.
    The argument for modal collapse is partly responsible for the widespread rejection of the so-called Principle of Sufficient Reason in recent times. This paper discusses the PSR against the background of the recent debate about grounding and develops principled reasons for rejecting the argument from modal collapse.

    Compatibilism and the notion of rendering something false
    Philosophical Studies 117 (3): 409-428. 2004.
    In my paper I am concerned with Peter van Inwagen's Consequence Argument. I focus on its probably best known version. In this form it crucially employs the notion of rendering a proposition false, anotion that has never been made sufficiently clear. The main aim of my paper is to shed light on thisnotion. The explications offered so far in thedebate all are based on modal concepts. Iargue that for sufficient results a ``stronger'', hyper-intensional concept is needed, namely the concept expresse…Read more

    Property Designators, Predicates, and Rigidity
    Philosophical Studies 122 (3): 227-241. 2005.
    The article discusses an idea of how to extend the notion of rigidity to predicates, namely the idea that predicates stand in a certain systematic semantic relation to properties, such that this relation may hold rigidly or nonrigidly. The relation (which I call signification) can be characterised by recourse to canonical property designators which are derived from predicates (or general terms) by means of nominalization: a predicate signifies that property which the derived property designator …Read more

    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

    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

    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.

    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

    On what we can ensure
    Synthese 162 (1). 2008.
    The Conjunction Principle says, roughly, that if the truth of a conjunction can be brought about, then the truth of each conjunct can be brought about. The current essay argues that this principle is not valid. After a clarification of the principle, it is shown how a proper understanding of the involved notions falsify the principle. As a corollary, a recent attack on van Inwagen’s Consequence Argument will be rebutted, because it relies on the invalid conjunction principle.

    In describing and classifying things we often rely on their modal characteristics. We will in general not have a satisfactory account of the nature and character of an object, unless we specify at least partly how the thing might be or cannot be, and also how it might have been or could not have been. In his contribution to the Second Jerusalem Philosophical Encounter,1 Strawson addressed the issue of how to understand such ascriptions of modal characteristics. Although his paper is terse and pr…Read more

    Attributing Properties
    American Philosophical Quarterly 43 (4). 2006.
    The paper deals with the semantics and ontology of ordinary discourse about properties. The main focus lies on the following thesis: A simple predication of the form ‘a is F’ is synonymous with the corresponding explicit property-attribution ‘a has F-ness’. An argument against this Synonymy Thesis is put forth which is based on the thesis that simple predications and property-attributions differ in their conditions of understanding. In defending the argument, the paper accounts for the way in wh…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.

    Once More: Bradleyan Regresses
    In Herbert Hochberg & Kevin Mulligan (eds.), Relations and predicates, Ontos Verlag. pp. 219-256. 2013.
    ld English manors have their ghosts. And though I would not want to call analytic philosophy a ‘manor’, nor exactly ‘old’, it certainly is of some decent English origin, and it left adolescence a while ago. No wonder then, that it is not exempt from haunting terrors. One particular spectre has been haunting it for decades; it already gave some analytic pioneers the creeps, and we still now and then find people terrified by it: the ghost of old Bradley has not yet found its rest and keeps on thre…Read more

    Particularised Attributes
    In M. Textor (ed.), The Austrian Contribution to Analytic Philosophy, Routledge. pp. 1--130. 2006.
    For philosophers interested in ontological issues, the writings of the important figures of Austrian philosophy in the nineteenth and early twentieth century contain many buried treasures to rediscover. Bernard Bolzano, Franz Brentano, Alexius Meinong, and Edmund Husserl, to name just four grand names of that period, were highly aware of the importance of a feasible ontology for many of the philosophical questions they addressed throughout their works.

    Truth-functionality
    Review of Symbolic Logic 1 (1): 64-72. 2008.

    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

    The main question of this paper is how to understand the notion of a truth-maker. In section 1, I show that the identification of truth-making with necessitation cannot capture the pretheoretic understanding of notions such as ‘x makes something true’. In section 2, I examine Barry Smith’s reaction to this problem: he defines truth-making as the combination of necessitation and projection. I focus on the formal part of Smith’s account, which is shown to yield undesired results. However, in secti…Read more

    Explanation by induction?
    Synthese 190 (3): 509-524. 2013.
    Philosophers of mathematics commonly distinguish between explanatory and non-explanatory proofs. An important subclass of mathematical proofs are proofs by induction. Are they explanatory? This paper addresses the question, based on general principles about explanation. First, a recent argument for a negative answer is discussed and rebutted. Second, a case is made for a qualified positive take on the issue.

    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

    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

    The importance of 'being earnest'
    Philosophical Quarterly 57 (226): 40-55. 2007.
    Reference to properties is normally achieved by the use of nominalizations of predicative expressions. I examine the relation between different kinds of these: while, traditionally, the terms 'wisdom' and 'the property of being wise' were thought to be co-referential, in certain contexts they do not seem to be interchangeable salva veritate. Observing this, Friederike Moltmann claims that abstract nouns such as 'wisdom' do not refer to properties. I argue that her theory is flawed and that the e…Read more
