Research Interests

Part of my philosophical work is focused on the nature of time.

  • In my Distance-Based Temporal Pluralism, which is based on my doctoral dissertation, I develop a new, innovative theory of time. This theory can be regarded as providing a novel answer to the age-old question what time is. My strategy is to provide a precisification of the concept of time. In particular, I provide a precisification in terms of an ontology, which postulates a plurality of different temporal determinations of things. Paradigmatic examples of such temporal determinations include the persistence of things, various types of change – such as beginnings, and endings and various kind-specific developments in between – causal relations, as well as the modal-temporal determinations of presentness, pastness and futurity. What all of these determinations have in common is that they are ontologically dependent on temporal distance relations (although not vice versa), as provided by relativistic chrono-geometry. The monograph offers a comprehensive view of temporal reality, and I employ the theory for addressing various issues that are prominently discussed between philosophers of time. Amongst other things, I set out to (a) defend a substantivalist conception of space-time, by arguing that spatio-temporal structure is inter alia required for definitional purposes, (b) propose an eternalist view by providing a new argument against presentism, which is that the presentist ontology runs into conflict with the symmetries of space-time, (c) extend the standard B-theoretic account of modal-temporal determinations, by showing how presentness, pastness and futurity arise vis-à-vis representations of physical objects within suitably located cognitive subjects of experience, and (d) clarify the nature of temporal passage, by equating passage with the observation of persisting things changing.
  • In my Theories of Time and Talk about Dynamical Time, I consider how different theories of time can plausibly account for the semantics of dynamical-time-talk. Natural languages like English and Urdu contain a remarkable variety of forms, which seem to attribute a dynamical quality to time. Thus speakers of English say that time is flowing, but also that time is passing, and running (out), or flying (by), and so on. In this paper, I examine how the semantics of such talk can be accounted for, depending on whether one proposes a dynamical A-theory, or spatializing B/C-theory of time.
  • In my Monism and The Persistence of It All, I explore the relation between monism and theories of persistence. How is the One from a diachronic point of view? The question of persistence has not been given much attention in the literature on monism. This is unfortunate since putting the question allows for deciding between different conceptions of the monist view. There is a longstanding debate whether monism conveys a timeless view of reality, or whether the One is more plausibly regarded as a temporal entity, like an eternal present. The fact that we can reasonably examine how the One persists suggests that monism is best construed as a temporal view, even though the One is widely taken to be unchangeable. In discussing this issue it turns out that monism is straightforwardly incompatible with some of the standard theories of persistence, including perdurantism and exdurantism. Since there is also a worry about wedding monism to endurantism, our discussion suggests that the monist ontology is best combined with non-standard conceptions of persistence, such as non-perdurantist four-dimensionalism.

 

A different part of my work is focused on the nature of timeless things. Thus in my Timeless Things, I introduce various candidates for timeless things, ranging from fundamental physical structures over mathematical structures to Platonic universals, and examine which of these are plausible candidates for timeless things.

Another part of my work is focused on social ontology. Together with Ludger Janssen, I am preparing an edited volume on the ontology of bands and other musical groups. This volume is supposed to include work from various ontologists addressing the nature of rock bands, classical orchestras, jazz-ensembles, and so on. My own contribution, Listen to the Band!, explores the nature of popular music groups.

Still other part is focused on the philosophy of language. More specifically, I focus on the ontology of language, and address the question what kind of thing language is. In this context, I develop an emergentist theory of meaning, according to which meaningful language can be regarded as emergent phenomenon.

Additionally, I have a serious interest in feminist philosophy of language, with questions relating to male bias, sub-ordination and and silencing.
