Abstract
This paper is aimed to analyze some grounds bridging the explanatory gap in philosophy of mind and linguistic sign theory. It's noted that the etymological ties between the notions of “consciousness", “cognition", “sign" are emphasized in the works on cognitive linguistics. This connection rises from the understanding of the symbolic nature of consciousness and the sign of semiosis as the key cognitive process. On the one hand, it is impossible to realize the communication procedures, knowledge, understanding, decisionmaking, orientation and even navigation without the process of signification. On the other hand, the human mind has its unique ability to produce the meaning apart from the “signal markings" available to other living beings. The ontology of this ability should be considered as a part of the complex problem of consciousness which includes the mind-body problem, the free will problem, image memory, narrative worlds, introspection, etc. In this paper, special attention is paid to the ontological and epistemological aspects of linguistic sign within the context of the bio-semiotic approach. The author argues that the linguistic nature of consciousness is inseparably connected with the ontological properties of consciousness. The author makes an attempt to prove the link between the mind-body problem and the problem of the explanatory gap in the ontology of linguistic sign. The analysis is focused on the following question: Is it possible that the rank of random names could cause the behavior of the organism in changing environment?
