conference paper description
In an event ontology, matter is 'made up of' events. This provides a distinctive foil to the standard view of a quantum state in terms of properties possessed by a system. Here I provide an argument against the standard view and suggest instead a way to conceive of quantum mechanics in terms of probabilities for the occurrence of events localized in space and time. To that end I construct an appropriate probability space for these events and give a way to calculate them as conditional probabilities. I suggest that these probabilities can be usefully thought of as Lewisian objective chances.
