About me

I'm an Assistant Professor of Philosophy at the University of Maryland, College Park. I work mainly in philosophy of science and metaphysics.

I'm currently working on projects about the value of the special sciences in a world of physics, about the Humean approach to laws of nature, and about when facts call out for explanation.

I also have research interests in philosophy of economics, philosophy of physics, and epistemology.

Before coming to Maryland I received my PhD from NYU in 2017. My thesis was about explanation in the special sciences. Before that I did a B.Phil in Philosophy and a BA in Philosophy, Politics and Economics, both at the University of Oxford.

My email is bhogal@umd.edu.

Here is a CV.

Also, I'm on Philpeople.

• “Difference-making and Deterministic Chance”
  Philosophical Studies, Forthcoming (Abstract) (PDF)
  
  

  Why do we value higher-level scientific explanations if, ultimately, the world is physical? An attractive answer is that physical explanations often cite facts that don't make a difference to the event in question. I claim that to properly develop this view we need to commit to a type of deterministic chance. And in doing so, we see the theoretical utility of deterministic chance, giving us reason to accept a package of views including deterministic chance.

• “Induction and the Glue of the World”
  Australasian Journal of Philosophy, Forthcoming (Abstract) (PDF) (Published Version)
  
  

  Views which deny that there are necessary connections between distinct existences have often been criticized for leading to inductive skepticism. If there is no glue holding the world together then there seems to be no basis on which to infer from past to future. However, deniers of necessary connections have typically been unconcerned. After all, they say, everyone has a problem with induction. But, if we look at the connection between induction and explanation, we can develop the problem of induction in a way that hits deniers of necessary connections, but not their opponents. The denier of necessary connections faces an `internal' problem with induction -- skepticism about important inductive inferences naturally flows from their position in a way that it doesn't for those who accept necessary connections. This is a major problem, perhaps a fatal one, for the denial of necessary connections.

• “Humeanism about Laws of Nature”
  Philosophy Compass, Forthcoming (Abstract) (PDF) (Published Version)
  
  

  Humeanism about laws of nature is, roughly, the view that the laws of nature are just patterns, or ways of describing patterns, in the mosaic of events. In this paper I survey some of the (many!) objections that have been raised to Humeanism, considering how the Humean might respond. And I consider how we might make a positive case for Humeanism. The common thread running through all this is that the viability of the Humean view relies on the Humean having an importantly different conception of explanation to the anti-Humean.

• “Coincidences and the Grain of Explanation”
  Philosophy and Phenomenological Research, 2020 (Abstract) (PDF) (Published Version)
  

  
  I give an account of what makes an event a coincidence.

  I start by critically discussing a couple of other approaches to the notion of coincidence -- particularly that of Lando (2017) -- before developing my own view. The central idea of my view is that the correct understanding of coincidences is closely related to our understanding of the correct 'level' or 'grain' of explanation. Coincidences have a kind of explanatory deficiency — if they did not have this deficiency they would not be coincidences. This deficiency, I claim, is the same explanatory deficiency as when we give low-level explanations of special science phenomena. Such explanations are typically too specific and not robust enough. I claim that there is this same badness in purported explanations of coincidences.

  I cash out this idea sketching an account of explanatory goodness — an account of what makes explanations better or worse -- and using that to give a more precise account of coincidences.

• “Nomothetic Explanation and Humeanism about Laws of Nature”
  Oxford Studies in Metaphysics, Volume 12, 2020 (Abstract) (PDF)
  Winner of the 2018 Sanders Prize in Metaphysics

  
  Humeanism about laws of nature — the view that the laws reduce to the Humean mosaic — is a popular view, but currently existing versions face powerful objections. The non-supervenience objection, the non-fundamentality objection and the explanatory circularity objection have all been thought to cause problems for the Humean. However, these objections share a guiding thought — they are all based on the idea that there is a certain kind of divergence between the practice of science and the metaphysical picture suggested by Humeanism.

  I suggest that the Humean can respond to these objections not by rejecting this divergence, but by arguing that is appropriate. In particular the Humean can, in the spirit of Loewer (2012), distinguish between scientific and metaphysical explanation — this is motivated by differing aims of explanation in science and metaphysics. And they can further leverage this into distinctions between scientific and metaphysical fundamentality and scientific and metaphysical possibility. We can use these distinctions to respond to the objections that the Humean faces.

• “What the Humean should say about Entanglement” (with Zee R Perry)
  Noûs, 2017 (Abstract) (PDF) (Published Version)

  
  Tim Maudlin has influentially argued that Humeanism about laws of nature stands in conflict with quantum mechanics. Specifically Humeanism implies the principle Separability: the complete physical state of a world is determined by the intrinsic physical state of each space-time point. Maudlin argues Separability is violated by the entangled states posited by QM.

  We argue that Maudlin only establishes that a stronger principle, which we call Strong Separability, is in tension with QM. Separability is not in tension with QM. Moreover, while the Humean requires Separability to capture the core tenets of her view, there's no Humean-specific motivation for accepting Strong Separability.

  We go on to give a Humean account of entangled states which satisfies Separability. The core idea is that certain quantum states depend upon the Humean mosaic in much the same way as the laws do. In fact, we offer a variant of the Best System account on which the systemization procedure that generates the laws also serves to ground these states.

  We show how this account works by applying it to the example of Bohmian Mechanics. The 3N-dimensional configuration space, the world particle in it and the wave function on it are part of the best system of the Humean mosaic, which consists of N particles moving in 3-dimensional space. We argue that this account is superior to the Humean account of Bohmian Mechanics defended by Loewer and Albert, which takes the 3N-dimensional space, and its inhabitants, as fundamental.

• “Minimal Anti-Humeanism”
  Australasian Journal of Philosophy, 2017 (Abstract) (PDF) (Published Version)

  
  I argue that there is a tension in our theorizing about laws of nature. We have powerful reasons to think that laws are not universal generalizations -- if they are we would face the problem of explanatory circularity. But we have powerful reasons, stemming from our practice of using and reasoning with laws of nature, to think that laws are universal generalizations.

  I start by elucidating this tension. I then suggest a view of laws that avoids this tension -- I call it Minimal anti-Humeanism. The view says that the laws are the universal generalizations that are not grounded in their instances. This view has advantages in addition to avoiding the tension -- for example, it is ontologically minimal and provides clear answers to the classic identification and inference problems for accounts of law. I end by locating the view in the Humean versus anti-Humean debate. The view turns out to be not easy to classify in these terms -- as the name suggests, I think it is best understood as an anti-Humean view, but reasonable people could disagree. Either way, the view is one which could be attractive to people with both Humean and anti-Humean inclinations.
