It examines the peculiaritiesof language research approaches as an instrument of harmonious lifestyle of the people as wellas an important means of creation of evaluative worldview. The aim of this paper is to demonstratethe eсo-cognitive grounds of evaluation category. The paper grounds on theses and techniquesof evaluation, cognitive, eco-cognitive and biocognitive theories.Ecolinguistics as a research field that combines ecology and linguistics studies the interactionbetween language, human being as a language personality and his environment. The anthropocentricand eco-centric lines may be distinguished as reasonable forms in the development of contemporaryhumanitarian sciences for the reason that they establish different interpretations in investigatingdevelopment and outcomes of human activity. Axiological aspect of natural environment preservationhas contradicted the anthropocentric outlook, as a result the principles of ecological ethics are thoughtto be much more important for the issue of human survival than anthropocentric ideals of value.Evaluation is a fundamental constituent of cognition, which is based on a value approachto the phenomena of nature and society. So, person's activity and life as of a human being havingdifferent requirements, interests and objectives is impossible without estimation. The paper looksat the evaluation concept as the formation which consists of a nucleus, which is the custodianof the collective knowledge of a particular people, and a periphery that is filled by the subjectiverepresentations of the native speaker of that language. The evaluation concept is an independent mentalformation that is culturally specified. It is considered to be a part of the conceptual and languageworldview of a certain linguocultural community, and can be defined as their structural component.
