 The various aspects Plato associated with the dynamic movements of the lower soul were more systematically discussed in Aristotle’s theory of emotions as part of the human condition. Aristotle developed a detailed model for analyzing the psychological structure of occurrent emotions, which included four basic aspects, most extensively discussed in the section on emotions in the second book of the Rhetoric. First, the cognitive element is an unpremeditated evaluation (belief or phantasy) that something positive or negative happens or may happen to the subject or to someone else in a way which concerns the subject. Second, the affective element is a subjectively felt pleasant or unpleasant feeling about the content of the evaluation. Third, the dynamic element is a behavioral impulse towards action which typically accompanies emotional evaluation. Fourth, there are typical physiological reactions such as the changes in the heartbeat. (For emotions in Plato and Aristotle, see Cooper 1999; Fortenbaugh 2003; Lorenz 2006; Price 2010; Dow 2015.)
