    Meta-metaphysics
    Routledge Encyclopedia of Philosophy. 2018.
    Meta-metaphysics concerns the nature and methodology of metaphysics and metaphysical inquiry. The emergence of meta-metaphysics as a systematic area of study is relatively recent, going back to the late 1990s. But the issues pursued in meta-metaphysics are certainly not novel: an age old question about the nature of metaphysics is whether it is possible to obtain knowledge about metaphysical matters in the first place, and if it is, how this knowledge is obtained.

    This paper is a survey of the positive and negative aspects of cannabis use from the point of view of the individual on one hand and from the point of view of the society on the other hand. Health, social, and political motives are all discussed, and the best method of harm reduction is analysed. The upshot is that zero tolerance policy is obsolete, and that most individuals would be better off using cannabis rather than other drugs.

    A Survey of Logical Realism
    Synthese 198 (5): 4775-4790. 2021.
    Logical realism is a view about the metaphysical status of logic. Common to most if not all the views captured by the label ‘logical realism’ is that logical facts are mind- and language-independent. But that does not tell us anything about the nature of logical facts or about our epistemic access to them. The goal of this paper is to outline and systematize the different ways that logical realism could be entertained and to examine some of the challenges that these views face. It will be sugges…Read more

    A Priori or A Posteriori?
    In Ricki Bliss & James Miller (eds.), , Routledge. pp. 353-363. 2020.
    This article discusses the role of a priori and a posteriori knowledge and methods in metaphysics and metametaphysics. Issues discussed include the viability of the distinction, the continuity of a priori and a posteriori methods, connections to modal epistemology, and the role of the distinction for science and naturalistic metaphysics.

    Introduction to my 'Contemporary Aristotelian Metaphysics' volume.
  •  453
    The title of this paper reflects the fact truthmaking is quite frequently considered to be expressive of realism. What this means, exactly, will become clearer in the course of our discussion, but since we are interested in Armstrong’s work on truthmaking in particular, it is natural to start from a brief discussion of how truthmaking and realism appear to be associated in his work. In this paper, special attention is given to the supposed link between truthmaking and realism, but it is argued t…Read more

    Against the vagueness argument
    Philosophia 37 (2): 335-340. 2009.
    In this paper I offer a counterexample to the so called vagueness argument against restricted composition. This will be done in the lines of a recent suggestion by Trenton Merricks, namely by challenging the claim that there cannot be a sharp cut-off point in a composition sequence. It will be suggested that causal powers which emerge when composition occurs can serve as an indicator of such sharp cut-off points. The main example will be the case of a heap. It seems that heaps might provide a ve…Read more

    Disentangling Nature's Joints
    In William Simpson, Robert Koons & Nicholas Teh (eds.), Neo-Aristotelian Perspectives on Contemporary Science, Routledge. pp. 147-166. 2017.
    Can the neo-Aristotelian uphold a pluralist substance ontology while taking seriously the recent arguments in favour of monism based on quantum holism and other arguments from quantum mechanics? In this article, Jonathan Schaffer’s priority monism will be the main target. It will be argued that the case from quantum mechanics in favour of priority monism does face some challenges. Moreover, if the neo-Aristotelian is willing to consider alternative ways to understand ‘substance’, there may yet b…Read more

    Bundle Theory with Kinds
    Philosophical Quarterly 69 (277): 838-857. 2019.
    Is it possible to get by with just one ontological category? We evaluate L.A. Paul's attempt to do so: the mereological bundle theory. The upshot is that Paul's attempt to construct a one category ontology may be challenged with some of her own arguments. In the positive part of the paper we outline a two category ontology with property universals and kind universals. We will also examine Paul's arguments against a version of universal bundle theory that takes spatiotemporal co-location instead …Read more

    Structure
    In Michael J. Raven (ed.), The Routledge Handbook of Metaphysical Grounding, Routledge. pp. 387-395. 2020.
    An exploration of ground’s connections to structure (joint-carving, naturalness). The notion of structure is often invoked in connection to ground, because grounding is understood to impose constraints on the ‘structure of reality’. There is another, technical sense of structure, sometimes captured with reference to the notion of ‘joint-carving’. Both of these senses of structure as well as their potential connections are discussed.

    Fundamentality
    Stanford Encyclopedia of Philosophy. 2018.
    The notion of fundamentality, as it is used in metaphysics, aims to capture the idea that there is something basic or primitive in the world. This metaphysical notion is related to the vernacular use of “fundamental”, but philosophers have also put forward various technical definitions of the notion. Among the most influential of these is the definition of absolute fundamentality in terms of ontological independence or ungroundedness. Accordingly, the notion of fundamentality is often associated…Read more

    Contemporary Aristotelian Metaphysics (edited book)
    Cambridge University Press. 2011.
    Aristotelian metaphysics is currently undergoing something of a renaissance. This volume brings together fourteen essays from leading philosophers who are sympathetic to this conception of metaphysics, which takes its cue from the idea that metaphysics is the first philosophy. The primary input from Aristotle is methodological, but many themes familiar from his metaphysics will be discussed, including ontological categories, the role and interpretation of the existential quantifier, essence, sub…Read more

    Title in English: "Empirical elements in modal epistemology". This article examines Peter van Inwagen's modal scepticism and argues that although van Inwagen is correct to criticise modal rationalism, there are tools in modal empiricism that are promising sources of modal knowledge.

    Ground, essence, and modality seem to have something to do with each other. Can we provide unified foundations for ground and essence, or should we treat each as primitives? Can modality be grounded in essence, or should essence be expressed in terms of modality? Does grounding entail necessitation? Are the notions of ground and essence univocal? This volume focuses on the links—or lack thereof—between these three notions, as well as the foundations of ground, essence, and modality more generall…Read more

    Unity of Science
    Cambridge University Press. 2021.
    Unity of science was once a very popular idea among both philosophers and scientists. But it has fallen out of fashion, largely because of its association with reductionism and the challenge from multiple realisation. Pluralism and the disunity of science are the new norm, and higher-level natural kinds and special science laws are considered to have an important role in scientific practice. What kind of reductionism does multiple realisability challenge? What does it take to reduce one phenomen…Read more

    This is a contribution to Paavo Pylkkänen's Festschrift. I discuss his relationship to Bohm's philosophy and a sense of holism that can be extracted from the Bohmian view.
