We are dangerous when we don't understand the responsibility we have for how we act, feel and think, says Marshall Bertram Rosenberg, American psychologist, mediator, author and professor. In fact, each person bears a particular responsibility for what they say, influenced or not, by the mood they are in at the time. Emotivity is considered a linguistic category, which classifies the affective/emotive lexicon (linguistic means that designate emotions according to the presence of semantic emotional signs or affective, connotative or potentially affective lexemes). Assuming that all discourses have a direct or indirect link to a field of science, then each of them can be called scientific, but not every field can be a science. Thus, scientific discourse is a discourse that is as fixed as it is variable. Considering the stage at which science has advanced, we can say that it focuses more on abstraction, schematization, sketching. By emotionality in scientific discourse we mean the inherent semantic property of language to express emotionality as a fact of the psyche, reflected in the semantics of language units, social and individual emotions. The essence of emotional content is subjective evaluation, which is the source of the speaker's emotional state or attitude. Emotionality in scientific discourse is realized in the form of the natural actualization of the author's intention to speak, which is his natural instinct, motivated by the classification of his knowledge through its emotionally meaningful verbalization. A scientific discourse can challenge emotions of interest, anticipation and alertness, but also other emotions, depending on the discussed subject.
