Abstract This is a philosophical paper. It deals with the interpretation of quantum mechanics, i.e., with reality, the objects of quantum mechanics, probabilities, etc. It is important to distinguish between real things and physical systems. A physical theory is a collection of rules for predictions on the outcome of measurements. Contrary to general belief “prediction” and “possible and actual” are key concepts in physics, as well as the concept of probability, being the most general empirically testable prediction. The Copenhagen interpretation is nothing but a “minimal semantics” of quantum mechanics, dealing with possibilities rather than with facts. Quantum mechanical realism is the futile attempt to confine physics to the description of facts. We answer the old question whether probability is about single events or about series of events: it can be about either, if it is correctly interpreted as a representative of the abstract ensemble. Quantum mechanics is only interesting if it is the most general theory of all possible systems. But this is where the hard problems arise: measurement, reality, indeterminism, etc. These problems can be solved if we accept seriously the key role of prediction and possibility, and abandon the ontology of classical physics.
