One of the most prominent areas of causal modeling today sounds out the interaction of probabilistic and deterministic approaches and is centered around Bayesian Networks, through which causal notions can be identified concretely and utilized for various disciplines eventually.

The workshop "Concrete Causation" was hosted by the LMU Institute for Logic and Philosophy of Science and took place on July 9, 2010. Amongst others Wolfgang Spohn (Konstanz) was talking about his Ranking Theory.

On occasion of the MCMP workshop on mathematical philosophy (13 & 14 Sep 2011) as part of the DGPhil conference 2011, Roland Poellinger gave a short presentation titled "Disentangling Nets for Causal Inference". The topics: What problems arise, when Bayes net causal models are augmented by the insertion of non-causal, non-directional knowledge? How can structural knowledge about given situations be enriched to decide about the utility of available semi-DAGs? And is there any possibility to regain the Markov condition for consistent computation of causal claims from graphs that unify directional and undirectional information? Watch the talk on iTunes U!

The seminar "The Cement of the Universe - Recent Topics in the Theory of Causation" will be organized by members of the LMU philosophy department, March 22-26, 2010. The announcement states that ...

"for some time it has seemed that causation – once dubbed by J.L. Mackie the cement of the universe – would no longer play a major role in metaphysics and philosophy of science. It appeared that in the course of scientific progress – as Bertrand Russell had predicted at the beginning of the 20th century – causal concepts would be gradually supplanted by lawlike correlations and thus become superfluous. Recent years however have seen a revival of philosophical and scientific interest in questions concerning causal relations."

R. Poellinger's talk about Judea Pearl, "Causality" (2000/2009), Pearl's deterministic account of causation, and his answer to David Lewis' counterfactual approach will be part of the session about probabilistic logic.

## Talk "Reclaiming Markov in Entangled Structures of Deterministic Causal Knowledge" @ CMU Pittsburgh (30 Nov and 7 Dec 2011, 5pm)

On 30 Nov 2011 Roland Poellinger will give a talk at the Center for Formal Epistemology of Carnegie Mellon University, Pittsburgh, titled "Reclaiming Markov in Entangled Structures of Deterministic Causal Knowledge – Part 1: Epistemic Contours" (5pm, Baker Hall 150). This talk will concentrate on the observation that in many cases of causal reasoning non-causal, non-directional knowledge is drawn on and computed efficiently and consistently, although reasoning with this kind of knowledge seems to violate the causal Markov condition in standard Bayes net causal models. Examples are found in causal decision theory, where modeling Newcomb’s paradox (in its original formulation) or the prisoners’ dilemma seemingly yields counter-intuitive solutions, or in cases of inter-level (e. g., genuine bottom-up or top-down) causation that are usually simply collapsed to “flat” models incorporating (unanalyzed) cross-level mechanisms. Intermediate stages in the process of reducing theories, learning, or modeling given situations (e. g., stages with intensionally separated but extensionally equal variables) find no formalized expression in causal models obeying Markov. Embedding “entangled” variables in causal models renders those models non-Markovian. If we want to stick with these models, how can Markov be reclaimed?

Part 2 of the talk, "The Principle of Explanatory Dominance", will take place on 7 Dec 2011 (5pm, Baker Hall 150).
