10th Quarterly Lecture

Perspectival Realism. An introduction

Venue: Online

Background reading: Massimi, Perspectival Realism

Abstract: In this talk I give an overview of the philosophical view called Perspectival realism which I articulated in Massimi (2022, OUP). I present the epistemological approach to science that underpins the view with the question of how reliable scientific knowledge is produced. In the second part of the talk I elucidate the realist position that results from the epistemological project with a focus on a phenomena-first ontology.

Four Grades of Modal Naturalism

Venue: Online

Video; Background reading: The Nature of Contingency. Quantum Physics as Modal Realism

Abstract: How, if at all, can scientific progress improve our view of the modal facts? According to rationalist approaches to modal epistemology, science has no substantive role: a priori reflection reveals the structure of modal space, and a posteriori science merely locates us within that modal space, by identifying the actual properties and structures instantiated at our world. According to modal naturalist approaches, science provides evidence about the structure of the underlying modal space. In this paper I distinguish four versions of modal naturalism, with science playing an increasingly robust evidential role, and discuss their plausibility.

Methodological Naturalism and Context Dependence

Venue: Online

Video; Background reading: Naturalism Beyond the Limits of Science: How Scientific Methodology Can and Should Shape Philosophical Theorizing (esp. chapters 1,2,3, and 7)

Abstract: Methodological naturalism is the view that metaphysicians ought to follow as much of the methodology of science as possible. I present an argument for methodological naturalism and explore some interesting consequences of the view. Then I turn to what I take to be the most significant challenge facing the methodological naturalist. This challenge stems from the observation that the methodology of science appears to be context dependent in various ways. I explore a range of possible ways by which the methodological naturalist might meet this challenge.

7th Quarterly Lecture
Lina Jansson

Symmetries and Conservation Laws

Venue: Online

Abstract: Symmetries are sometimes taken to explain conservation laws rather than vice versa. However, in common with many seemingly non-causal explanations, it is not easy to see how to justify this direction of explanation. In this talk I will present an epistemic account of explanation and the conditions that would have to be fulfilled in order for symmetries to explain conservation laws (but not vice versa).

Fast Science

Venue: Cologne University and online

Background reading suggested by the speaker: Birch (2021) and Stegenga (2020)

Abstract: Scientists violate principles and practices of routine science to quickly develop interventions against catastrophic threats. I call this fast science. The magnitude, imminence, and plausibility of a threat justify engaging in and acting on fast science. Yet, that justification is incomplete. I defend two principles to assess fast science, which say: fast science should satisfy as much as possible the reliability-enhancing features of routine science, and the fast science developing an intervention against a threat should not depend on the same problematic assumptions as the science which estimates the magnitude, imminence, and plausibility of the threat.

Programme 2022

4th Quarterly Lecture

Physics, Metaphysics, and the Problem of Progress

Video; Slides; Background reading: McKenzie (2020)

Abstract: Metaphysics is often held to be continuous with science. And in many respects it is: it has similar aims and may even employ a similar methodology. However, it is arguably very different in one crucial respect: while science clearly makes progress, it is very much less clear that metaphysics does. This gravely impacts the value of engaging in metaphysics of physics prior to a final theory. Or so I think: in this talk I will explain why I believe this, and respond to some objections that have been made to my argument.

3rd Quarterly Lecture
Anjan Chakravartty

On the Relationship between Scientific Realism and Scientific Metaphysics


Abstract: Debates about scientific realism (the idea that our best theories and models are substantially on the right track, epistemically, and increasingly so), and debates about scientific or naturalized metaphysics (the idea that, in order to be on the right epistemic track, metaphysical theorizing should be intimately connected to scientific theorizing), are generally conducted in isolation from one another. As it happens, though, these two debates are, in fact, interwoven, because different approaches to scientific realism reflect different approaches to naturalized metaphysics, and antirealist arguments in the former domain have correlates in the latter. In this talk, I explore the relationship between scientific realism and scientific metaphysics, the extent to which their fates are linked, and the sense in which they are not.

2nd Quarterly Lecture
Emily Adlam
23. June 2022 (18:15 CEST)

Operational Theories as Structural Realism


Abstract: In this talk I will introduce the operational theories approach to research in quantum foundations and undertake a reconstruction of the epistemic significance of this research. I argue that the space of operational theories is analogous to the space of possible worlds employed in the possible world semantics for modal logic, so research of this sort can be understood as probing modal structure. Thus I will argue that operational axiomatisations of quantum mechanics may be interpreted as a novel form of structural realism; I discuss the consequences of this interpretation for the philosophy of structural realism and the future of operational theories.

Epistemological implications of Bell's inequality

Video, Script; Background reading: Mermin (1981)

Abstract: I will quickly rehearse the schematic form of the Aspect experiment to test Bell’s Inequalities. Then I will first explain how those inequalities can be deduced if we assume Reichenbach’s common cause principle, and next, if we assume counterfactual definiteness (made precise in terms of conditionals). Finally, there is still the challenge of how to go on once we have to give up traditional ways of thinking, and here I will advocate an empiricist stance toward modality.
