In this lesson, the concept of happiness according to Aristotle is discussed, emphasizing the idea of “eudaimonia,” which translates to good spirit or well-living. Unlike the contemporary understanding of happiness as a transient feeling, Aristotle’s concept includes harmony between the rational (intellect) and irrational (bodily desires and emotions) aspects of an individual. This holistic approach signifies fulfillment through the balance of one’s entire being, combining health, desires, emotions, and intellect.
