Abstract: The object of the research is the relationship between the definitions of teacher and scientist as well as realities behind these terms that are traditionally viewed as the crossing points. This is proved by the conjunction that is often used with these two terms in all kinds of contexts. The subject of the research is the particularities of a professional life of a teacher and a scientist that in many ways defines special personality traits of them both. The author of the article examines such aspects of the topic as the differences in a professional life of a scientist who creates new theoretical interpretations of natural and socio-humanitarian reality and a teacher who creates new forms and methods of explaining these interpretations to the students' audience. The researcher pays special attention to the analysis of the fact that a person who is a master of something is not necessarily a successful teacher of it. For example, someone who is fluent in a foreign language is not necessarily a great teacher of that language, a professional swimmer is not always a gifted swimming coach. To analyze the relationship between definitions of teacher and scientist and particularities of their professinal life, the author of the article has used such research methods as collection, observation and systematisation of empirical data, inductive generalisation, construction and analysis of schemes to describe the relationship between these terms, comparative analysis and mental experiment. The main conclusion of the research as well as the novelty thereof is the author's statement that the relationship between defnitions of teacher and scientist that is usually viewed as the crossing point can be also viewed as inconsistency or strict disjunction. Except for rare cases, scientist cannot be a successful teacher and teacher cannot be a successful scientist because they are in parallel although very closely related but completely different worldsas a result of different professional life, purposes and objectives of their activity, talents, abilities, skills, and personality traits. At the practical and institutional levels this conclusion can be expressed as a suggestion to replace traditional practice of 'consistent order' of academic credentials and degrees with the 'parallel order' by introducing some kind of a 'rank record' at higher schools.

Abstract: The problems of ethnopolitical relations that are usually called ‘the national issue’ are constantly discussed in both philosophical and psychological literature. As a rule, the modern global political process mobilizes groups based on ethnic grounds. The global community faces the fact that young countries with archaic or traditional ethnic groups have been included in the active historical process. Moreover, globalization has evoked opposition and separatist movements in a number of countries. There are many countries that want to become independent and autonomous today. At the same time, there are still many ethnic issues that remain unsolved. Nations demonstrate a growing interest towards their ethnic identity. The author of the present research article tries to make a distinction in interpretations of the ethnonational issues from the point of view of mordialism, constructivism and instrumentalism. The researcher uses the method of historical analysis that allows to describe how views on ethnos and ethnicity have been changing over the past decades and why the current definition of ethnicity has been created. The author also carries out a scientific analysis of works on the phenomenology of ethnicity. The scientific importance and novelty of the article is that the researcher compares modernistic and post-modernistic views on ethnicity issues. The researcher stresses out that formation of a nation or ethnos is based on social historical facts first of all. However, modern interpretation of ethnos also involves the analysis of imaginary works used in social constructivism.
