Essay from the year 2018 in the subject Psychology - Cognition, grade: 1, Egerton University, language: English, abstract: In philosophical and psychological fields, emotion is referred to as subjective and conscious experience that is primarily characterized by psycho-physiological expressions, mental states and biological reactions. It is mostly associated and deemed jointly influential with mood, personality, temperament, motivation and disposition. Over the years, emotion theory has, therefore, been illustrated by a dichotomy involving the body and head. In the 1960s and 1970s (cognitivism golden years), this theory focused on cognitive emotion antecedents, the so-termed as appraisal processes, with some philosophers perceiving bodily events as by-products of cognition, and as highly unspecific to contribute to emotion experience variety. In other words, they conceptualized cognition as an abstract and intellectual process that is detached from bodily events. Cognitivism legacy perseveres in treating bodily and cognitive events as separate emotion components, even though the present emotion theory has moved past this disembodied position by conceiving of emotions as comprising the two processes; cognitive processes like perception and attention, and bodily event such as behavior and arousal. However, it is evident that the body already highly contributed to the theories of emotion of Descartes, Spinoza and Hume since their arguments never implied that they denied other emotion aspects like cognition and evaluation. Rather, these three classical theorists considered emotions as psychosomatic states, each focusing on distinct emotion aspects as per their theories, but showing an intimate connection between the body and emotions that leads to a relationship between reason and emotions. Therefore, the purpose of this essay is to demonstrate the relation between reason and emotions by presenting the views of classical (pre-Jamesian) theories of Descartes, Spinoza and Hume.
