  "abstract": "Epistemological consequences of quantum nonlocality (entanglement) are discussed under the assumption of a universally valid Schr\\\"odinger equation in the absence of hidden variables. This leads inevitably to a {\\it many-minds interpretation}. The recent foundation of quasi-classical neural states in the brain (based on environmental decoherence) permits in principle a formal description of the whole chain of measurement interactions, including the {\\it behavior} of conscious observers, without introducing any intermediate classical concepts (for macroscopic \"pointer states\") or \"observables\" (for microscopic particle positions and the like) --- thus consistently formalizing Einstein's {\\it ganzer langer Weg} from the observed to the observer in quantum mechanical terms.",
