Generalized Quantum Theory, Contextual Emergence and Non-Hierarchic Alternatives

Quantum Interaction, 9th International Conference QI 2015, July 15-17 2015, Revised Selected Papers, pp. 157-167 The concept of emergence is critically analyzed in particular with respect to the assumed emergence of mental properties from a neuronal basis. We argue that so-called contextual emergence is needed to avoid an eliminatory reductionism. Quantum-like features of the emergent qualities are to be expected. As a consequence, non-causal relations like entanglement correlations have to be considered as full fledged elements of reality. "Observable extension" is proposed as a contextual alternative to emergence avoiding the asymmetry between purportedly basic and emergent properties.
