2.2 Sets of basic transitions

We provide a formally rigorous framework for integrating singular causation, as under stood by Nuel Belnap’s theory of causae causantes, and objective single case probab ilities. The central notion is that of a causal probability space whose sample space consists of causal alternatives. Such a probability space is generally not isomorphic to a product space. We give a causally motivated statement of the Markov condition and an analysis of the concept of screening off. 1 Causal dependencies and probabilitie
