0 The Problem of Conscious Observation in Quantum Mechanical Description

This is the retyped and slightly reformulated version of a paper that was circulated and semi-officially published already in 1981 in the Epistemological Letters of the Ferdinand-Gonseth Association in Biel (Switzerland) as Letter No 63.0. (Therefore, terms such as " new " or " recent " refer to that year.) This paper offered a " discussion of the epistemological implications of quantum theory ". In its Conclusion, it introduced the term " multi-consciousness interpretation " for a variant of the Everett interpretation that has since been rediscovered several times (more or less independently), and become known as a " many-minds interpretation ". Some comments and references have been added at the end.
