The Talk "Lewis und Pearl: Causation und Causality" (Wednesday, 18 Nov 2009,  room 021, Ludwigstr. 31, 6 p.m. c.t.) deals with two different analyses of cause-effect-relations – talk and discussion in German language.

Abstract:

David Lewis presents in Causation (1973) the counterfactual analysis of cause-effect-relations: If the cause c had not existed, the effect e would have been absent, too. As a means of evaluation Lewis offers a largely unspecified, global similarity measure (between worlds) in Possible World Semantics. Judea Pearl replies to this suggestion with a correlation based approach towards causation in Causality (2000). Possible causes are identified by local adjustment of distinguished and stable autonomous mechanisms – an approach that seems to be natural and operationally effective at the same time.
