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...

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...

The Bohmian formulation of quantum mechanics is used in order to describe the measurement process in an intuitive way without a reduction postulate in the framework of a deterministic single system theory. Thereby the motion of the hidden classical particle is chaotic during almost all nontrivial measurement processes. For the correct reproduction of experimental results, it is further essentia...

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...
