  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.
