Localizing the Singular Structure of Spacetime
– Franciszek Cudek

Abstract in alt text or read it here:
www.journals.uchicago.edu/doi/10.1086/...

#philsci #philsky
ABSTRACT. I argue that the singular structure of spacetime is best conceptualized as an extrinsic, non-local, but localizable, property of spacetime regions (of any size), and that there is no unique, best definition of a singular region of spacetime. There is, however, a schema that any adequate definition instantiates. Moreover, the question of what kind of incomplete curves witness singular structure is intimately connected to the question of what kind of curves represent possible trajectories of observers in physically reasonable motion.

Scepticism about Post Hoc Explainability and Idealized Models
– Aleks Knoks & Thomas Raleigh

Abstract in alt text or read it here:
www.journals.uchicago.edu/doi/10.1086/...

#philsci #philsky
ABSTRACT. Deep neural networks and other AI systems engineered using advanced machine learning techniques can tackle a wide range of tasks with proficiency that seems to match and even surpass human ability. Yet they are also notoriously opaque and worries surrounding their opacity have given rise to the burgeoning field of explainable artificial intelligence (XAI), with its large variety of explainability methods. This includes post hoc explainability methods that purport to explain opaque AI systems on the basis of their input–output behaviour alone, without looking into their inner workings. But many have expressed deep scepticism about post hoc explainability. We explore the two main objections that the sceptics have raised and argue that we shouldn’t be swayed by them. Using ideas from recent literature on scientific explanation, we draw a parallel between post hoc explainability methods and idealized models in science, and use the parallel in reply to the sceptics.

Scientific Contributions and Scientific Authorship

#philsci
ABSTRACT. As a non-consensually enlisted contributor to the article ‘What’s the Point of Authors?’, who has made virtually no contribution to it, I argue against its proposed re-conception of authorship. In particular, I argue that a core component of the account—namely, the conception of contributorship—is implausible, infeasible, undesirable, and, in far too many cases, unethical.

Explanatory Understanding in the Metaphysics of Science
– Peter Tan

Abstract in alt text or read the paper here:
www.journals.uchicago.edu/doi/10.1086/...

#philsci #philsky
ABSTRACT. This article develops a novel account of metaphysics’ explanatory contributions to the philosophy of science. A recent objection alleges that explanations of features of science in metaphysical terms are nothing more than rephrases of their target explananda. That is, these explanations are alleged to fail with respect to what has recently been called ‘explanatory distance’. In response, I show that putative explanations of the scientific image in metaphysical terms often exemplify an explanatory strategy found elsewhere in science, which I call type–token explanations. If successful, these explanations would achieve appropriate explanatory distance. Additionally, because this mode of explanation coheres with a pre-existing explanatory strategy in science, my account implies that the metaphysics of science can generate understanding about its target phenomena in the same way that scientific explanations can provide scientific understanding of their target explananda

Determinism and Asymmetry in General Relativity
– J B Manchak, Thomas Barrett, Hans Halvorson & James Weatherall

Abstract in alt text or read the paper here:
www.journals.uchicago.edu/doi/10.1086/...

#philsci #philsky
ABSTRACT. This article concerns the question of which collections of general relativistic spacetimes are deterministic relative to which definitions. We begin by considering a series of three definitions of increasing strength due to Belot. The strongest of these definitions is particularly interesting for spacetime theories because it involves an asymmetry condition called `rigidity' that has been studied previously in a different context by Geroch. We show how Belot's strongest definition is connected to a formal result emphasized by Weatherall. We then go on to explore other (stronger) asymmetry conditions that give rise to other (stronger) forms of determinism. We introduce a number of definitions of this type and clarify the relationships between them and the three considered by Belot. We show that there are collections of general relativistic spacetimes that satisfy much stronger forms of determinism than previously known. We also highlight a number of open questions.

How Do We Know If Animals Remember? Proximal Functions and the Distribution of Episodic Memory
– Arieh Schwartz & Alexandria Boyle

Abstract in alt text or read it here: www.journals.uchicago.edu/doi/10.1086/...

#philsci #philsky
ABSTRACT. Which animals have episodic memory? One reason this is difficult to answer is that episodic memory could be expected to vary across species, making it hard to give a principled account of what ‘counts’ as an episodic memory system. In this article, we propose that the investigation of episodic memory in animals should be guided by an account of its proximal proper functions: its most basic selected effects. In short, an animal has episodic memory if it has a memory system with the proximal functions of episodic memory. While there are many accounts of episodic memory’s distal functions, little attention has been paid to its proximal functions. To remedy this, we develop a preliminary account of episodic memory’s proximal functions and use this to evaluate existing evidence about episodic memory in animals.

Entanglement Swapping for Entanglement Realists
– Jørn Kløvfjell Mjelva

Abstract in alt text or read it here:
www.journals.uchicago.edu/doi/10.1086/...

#philsci #philsky
ABSTRACT. Delayed-choice entanglement swapping experiments have been argued to undermine realism about entanglement. One response has been to argue that the correlations displayed in delayed-choice entanglement swapping experiments have a different physical interpretation than the correlations in the non-delayed case. This strategy runs into problems when applied to cases of spacelike entanglement swapping, as it would appear to require one to either posit a privileged foliation of spacetime or otherwise accept that whether entanglement obtains is frame dependent. In this article, I present a realist-friendly account of entanglement swapping that circumvents this dilemma, in which entanglement is explicated via the notion of a common ground. The issue of frame dependence is resolved by adopting the past light-cone criterion for property attribution, and the correlations displayed in the spacelike entanglement swapping experiments are attributed to a joint common ground.

Algorithmic Randomness and Probabilistic Laws
– Jeffrey Barrett & Eddy Keming Chen

Abstract in alt text or read it here:
www.journals.uchicago.edu/doi/10.1086/...

#philsci #philsky
ABSTRACT. We apply recent ideas about complexity and randomness to the philosophy of laws and chances, developing two ways to use algorithmic randomness to characterize probabilistic laws of nature: a generative chance law that employs a non-standard notion of chance, and a probabilistic constraining law that imposes relative frequency and randomness constraints that every physically possible world must satisfy. This removes an obstacle to a unified governing account of non-Humean laws, whereby laws govern by constraining physical possibilities; it also offers independently motivated solutions to problems for the Humean best-system account. On either approach, probabilistic laws are tied more tightly to corresponding sets of possible worlds: some histories permitted by traditional probabilistic laws are now ruled out as physically impossible. Consequently, the framework avoids one variety of empirical underdetermination while bringing to light others that are typically overlooked.

Kinematical Equivalence and Cosmic Conspiracies
– Caspar Jacobs & Eleanor March

Abstract in alt text or read it here:
www.journals.uchicago.edu/doi/10.1086/...

#philsci #philsky
ABSTRACT. Discussions of theoretical equivalence typically only concern a theory's dynamically possible models. Recently, however, March has shown that a theory's kinematically possible models are also relevant to questions of theoretical equivalence. We apply March's notion of kinematic equivalence to the difference between reduced and sophisticated theories introduced by Dewar. Although Dewar claims that these are equivalent, Jacobs has argued that only sophisticated theories can explain what are otherwise `cosmic conspiracies'. We show that this is a consequence of the kinematical inequivalence of reduced and sophisticated theories. Furthermore, we use Caulton's `downwards Hume's dictum' to show that kinematically inequivalent theories are also ontologically inequivalent.

Reviving Reduction
– Dominik Ehrenfels

Abstract in alt text or read it here:
www.journals.uchicago.edu/doi/10.1086/...

#philsci #philsky
ABSTRACT. Possessing symmetries often indicates that a theory’s models exhibit surplus structure, in turn suggesting the theory needs reformulation either by reduction or sophistication. Lately, sophistication has become more popular, on the grounds that reductions are difficult to find and often not as attractive. But this arises from a restrictive way of thinking about reduction. It is often held that theory reduction must be formulated in terms of symmetry-invariant quantities and must be empirically equivalent to the original. Using Barbour and Bertotti’s successful reformulation of Newtonian gravitation theory (NGT), I argue that reductions need not meet these criteria. While it is possible to sophisticate NGT with respect to scale symmetry, this has been a challenge for the reduction strategy, giving the impression that sophistication is superior. The approach to reduction I argue for here, however, is versatile enough to handle this case, arguably in a way superior to its rival.

Climate Sensitivity through the Lens of Measurement Practice
– Matthias Ackermann

Abstract in alt text or read it here:
www.journals.uchicago.edu/doi/10.1086/...

#philsci #philsky
ABSTRACT. In its Sixth Assessment Report, the IPCC moved from a climate model-based to a climate model-supported assessment of equilibrium climate sensitivity. Unlike previous reports, climate model information is no longer used directly for estimates of equilibrium climate sensitivity. I offer a measurement view on the equilibrium climate sensitivity assessment that allows us to evaluate this shift in practice in terms of its practical and epistemic consequences. In particular, I argue for two conclusions involved in this move. First, the change in using climate models as direct sources of evidence to a supporting role involves a kind of repurposing of climate models as epistemic tools. This change should be evaluated relative to the researchers' aims, which include more accurately assessing equilibrium climate sensitivity. Second, I suggest that this shift in practice shares a kinship to calibration activities aimed at increasing the reliability of a measurement procedure.

Statistical Autonomous Explanations and the Patterns of Nature: A Modified Account
– Travis Holmes & André Ariew

Abstract in alt text or read it here:
www.journals.uchicago.edu/doi/10.1086/...

#philsci #philsky
ABSTRACT. This article provides a fuller account of purely statistical pattern-level explanations—that is, those that explain macro-level events by invoking limit theorems. The statistical autonomous explanation account is modified via integration with the maximum entropy approach for generating limit distributions. This achieves two important results: (1) the range of statistical autonomous explanations is vastly extended and shown to range over many different kinds of limit distributions; (2) the modified account permits answers to questions about why these limit distribution patterns are so common in nature; why these patterns are robust; and also why these patterns are insensitive to most lower-level details pertaining to the characters or events that comprise the statistical ensemble. The modified account can be understood as a corrective for many extant accounts of statistical pattern-level explanations that fail to answer these crucial questions.

Sifting the Signal from the Noise
– Daniel Herrmann & Jacob VanDrunen

Abstract in alt text or read the full paper here: www.journals.uchicago.edu/doi/10.1086/...

#philsci #philsky
ABSTRACT. Signalling games are useful for understanding how language emerges. In the standard models, the dynamics in some sense already know what the signals are, even if they do not yet have meaning. In this article, we relax this assumption and develop a simple model we call an ‘attention game’, in which agents have to learn which feature of their environment is the signal. We demonstrate that simple reinforcement learning agents can still learn to coordinate in contexts where the agents do not already know what the signal is, and the other features in the agents’ environment are uncorrelated with the signal. Furthermore, we show that in cases where other features are correlated with the signal, there is a surprising trade-off between learning what the signal is and success in action. We show that the mutual information between a signal and a feature plays a key role in governing the accuracy and attention of the agent.
