The article discusses certain aspects of human communication viewed from the perspective of the anthropocentric language theory developed by F. Grucza. In the first part the author presents general principles of the anthropocentric language theory and explains the ontological status of language as an inherent attribute of a man. Along with two other inherent attributes of homo sapiens, i.e. its individual knowledge and culture, these three components form a triad of an integral cognitive device of a man. One of the key points of this theory consists in the elucidation of commonly mistaken comprehension of the so-called knowledge transfer allegedly occurring during the communication process. This transfer may only occur with reference to the stream of signs and not to the knowledge itself. The second part of the article is concerned with the process of specialist communication and certain determinant factors of successful communication. Among the underlying factors discussed are some linguistic as well as extra-linguistic skills whose classification is proposed by the author on the basis of the anthropocentric language theory.
