While emotion researchers with an evolutionary and biological orientation increasingly agree that small sets of discrete emotions are basic or primary, other researchers – particularly social constructionists – instead argue that all emotions are expressions of language and culture largely unconstrained by biology. Emotions are indeed socially and psychologically constructed, but not from scratch, for the basic emotions have evolved as biologically-structured adaptive reactions to the most fundamental problems of life, and have a deep evolutionary history. These life-problems were first identified in herpetology, and elaborated in Plutchik’s universal ethogram, a behavioral profile of four problems of life – identity, temporality, hierarchy, and territoriality – shared by a wide range of animal species. Plutchik proposed that the opposite poles of each of these dimensions can represent prototypical life-situations requiring rapid adaptive reactions; these reactions comprise the eight primary emotions. By hypothesizing that these dimensions have evolved into elementary social-relations models, we establish a continuity between the sociorelational and biological levels of emotional experience. Identification of eight basic emotions enables a classification of 24 secondary and 56 tertiary level emotions.
