Open Systems and Consciousness. A Physical Discussion

Further discussion of the author's ideas, as well as their confrontation with similar and different concepts of consciousness, have been given in the Introduction. Then the physical and, in lesser degree, also mathematical aspects of open systems, in particular of human person, are sketched in Sec. 2. The quantum concept of the decoherence time is treated as a model for a finite life-time of any composed physical and biological system. In Sec. 3 the role of languages of many types in living and non-living systems is briefly considered, as well as the importance of modality for sentence predicates. In Sec. 4, the structure of the cerebral neocortex and its speech centers is briefly described from the point of view of the mechanism of thinking and the consciousness. The concepts of laterality and dominance (left or right hemispheres of the brain) and their dependence on the type of culture and education are shown on the example of the differences between the Japanese and Western perception of languages (discoveries of Liberman and Tsunoda). In Secs. 5 and 6 the experimental evidence for the connection of consciousness with the speech centers are presented and some questions are posed.
