The concepts of complementarity and entanglement are considered with respect to their significance in and beyond physics. A formally generalized, weak version of quantum theory, more general than ordinary quantum theory of physical systems, is outlined and tentatively applied to two examples.

Synchronistic or psi phenomena are interpreted as entanglement correlations in a generalized quantum theory. From the principle that entanglement correlations cannot be used for transmitting information, we can deduce the decline effect, frequently observed in psi experiments, and we propose strategies for suppressing it and improving the visibility of psi effects. Some illustrative examples are discussed.

We present a scenario describing how time emerges in the framework of weak quantum theory. In a process similar to the emergence of time in quantum cosmology, time arises after an epistemic split of an undivided unus mundus as a quality of the individual conscious mind. Synchronization with matter and other mental systems is achieved by entanglement correlations. In the course of its operationalization, time loses its original quality and the time of physics as measured by clocks appears. avoided/explicated.

Process philosophy endeavors to replace the classical ontology of substances by a process ontology centered on the notions of change and transition. We argue that the substantial and processual approach are mutually complementary in the sense of a generalized quantum theory which is not limited to physical phenomena. From this point of view, restricting oneself to either substance ontology or process ontology would be as ill-advised as exclusively relying on position or momentum representations in physics. A new view on Zeno's (...) paradox lends itself. The meaning of a 'mental energy' observable, complementary to 'internal time', and its relationship to acategorial states of the human mind will be tentatively discussed. (shrink)

The main formal structures of generalized quantum theory are summarized. Recent progress has sharpened some of the concepts, in particular the notion of an observable, the action of an observable on states (putting more emphasis on the role of proposition observables), and the concept of generalized entanglement. Furthermore, the active role of the observer in the structure of observables and the partitioning of systems is emphasized.
