18 Feb: Luke Fenton-Glynn (UCL), “Probabilistic Actual Causation”

On Tuesday 18 February as part of the FraMEPhys Seminar series, Luke Fenton-Glynn (UCL) gave a talk entitled “Probabilistic Actual Causation” (Talk Slides, Full Paper) at the University of Birmingham. Luke presented an extension of recent theories of deterministic actual causation, formulated in terms of causal graphs, to irreucibly indeterministic cases.

ABSTRACT: Actual (token) causation – the sort of causal relation asserted to hold by claims like the Chicxulub impact caused the Cretaceous-Paleogene extinction event, Mr. Fairchild’s exposure to asbestos caused him to suffer mesothelioma, and the H7N9 virus outbreak was caused by poultry farmers becoming simultaneously infected by bird and human ’flu strains – is of significance to scientists, historians, and tort and criminal lawyers. Progress has been made in explicating the actual causal relation in the deterministic case by means of the use of structural equations models and causal graphs. I seek to make similar progress concerning the probabilistic case by using probabilistic causal models and associated causal graphs

Earlier on the same day, Luke took part in a reading group discussion of the above paper.

4 February 2020: Andreas Hüttemann, “Laws and their Modal Surface Structure”

For the second FraMEPhys meeting of 2020, Prof. Dr. Andreas Hüttemann (University of Cologne) gave a talk on “Laws and their Modal Surface Structure” at the University of Birmingham (Muirhead Tower, 427).

ABSTRACT: Law statements or generalisations are involved in one way or another in explanation, confirmation, manipulation or prediction. I argue that these practices require a particular reading of the generalisations involved, namely as making claims about the behaviour of systems. These practices therefore presuppose the existence of systems or things (pace Ladyman, Ross etc.). 
Furthermore, I look at the metaphysical surface structure associated with laws. I use the term “surface structure” to indicate that this structure may or may not be reduced to non-modal facts – as the Humean has it. I will side-line the debate about whether Humeanism is a tenable philosophical position. The positive claim I advance is that the modal surface structure can be explicated in terms of invariance relations – where I take invariance to be a modal notion.

Earlier on the same day, from 1130-1230 in ERI 159, Prof. Dr. Hüttemann attended a reading group where we discussed his “Reduction and Monism“.

21 January 2020: David Papineau, “The Seductions of Interventionism”

At the first FraMEPhys meeting of 2020 (21 January), Professor David Papineau (King’s College London) gave a talk on “The Seductions of Interventionism” at the University of Birmingham.

ABSTRACT: The philosophy of causation is changing. The new ‘interventionism’ promises to dissolve many longstanding problems. Based on the work of Judea Pearl, and transmitted to philosophy by Jim Woodward, this approach builds a bridge between the philosophical analysis of causation and techniques used in statistical causal modelling. It is certainly welcome that philosophers of causation are finally trying to make sense of these statistical techniques. But in the process of transmission a number of ungrounded ideas have been installed as philosophical orthodoxy. In this talk I shall expose two: first, the idea that we need to appeal to ‘interventions’ or actions to understand causation; second, the idea that correlational facts alone are insufficient to determine causal structure.

Earlier on the same day, Professor Papineau took part in reading group on his paper ‘Causation as a Guide to Life‘, which discussed some of the themes from his talk.
