A reconstruction of quantum theory refers to both a mathematical and conceptual paradigm that allows one derive the usual formulation from set primitive assumptions. The motivation for doing so is discomfort with theory, started its originator John von Neumann. We present finite-dimensional where all postulates are stated in diagrammatic terms, making them intuitive. Equivalently, they category...

The AGM model for the revision and contraction of belief sets provides rationality postulates for each of the two cases. In the context of finite propositional logic, Katsuno and Mendelzon pointed out postulates for the revision of belief bases which correspond to the AGM postulates for the revision of beliefs sets. In this paper, we present postulates for the contraction of propositional belie...

It is well-known that in finite strategic games true common belief (or common knowledge) of rationality implies that the players will choose only strategies that survive the iterated elimination of strictly dominated strategies. We establish a general theorem that deals with monotonic rationality notions and arbitrary strategic games and allows to strengthen the above result to arbitrary games,...

We argue that Koch's postulates are best understood within an interventionist account of causation, in the sense described in Woodward (2003). We show how this treatment helps to resolve interpretive puzzles associated with Koch's work and how it clarifies the different roles the postulates play in providing useful, yet not universal criteria for disease causation. Our paper is an effort at rat...
