This section explores the widespread impact of burnout in modern society, analyzes its relationship with various psychological disorders, traces the classical connotations of the term "burnout," and reveals its different possibilities and dimensions as an emotional "fold" through phenomenological dialogue.

Acedia: The Pre-History of Burnout

This section delves into the origins of the emotion "burnout" in Western cultural history, tracing it back to the ancient Greek word "acedia." Initially associated with the inhuman act of not burying the dead, it was later used by the Desert Fathers to describe psychological states such as listlessness and difficulty concentrating that emerged after a life of solitude, and was viewed as spiritual sloth. Evagrius Ponticus termed it the "noonday demon," emphasizing its complexity, persistence, and insidious nature, ranking it above the seven deadly sins, yet possible to overcome through prayer and other means. John Cassian further refined the manifestations of acedia, combining it with medical vocabulary, making it represent both sin and disease. Medieval figures like Thomas Aquinas and Dante provided profound expositions and depictions of acedia in their works, showcasing its far-reaching influence in Western culture.

Burnout as an Existentialist Philosophical Problem

This section examines burnout and related emotions, such as melancholy and boredom, from an existentialist philosophical perspective, pointing out their prevalence and complexity in modern society. From negative evaluations in classical societies to neutral or even aesthetic descriptions in modern times, emotions like burnout consistently exist within the interplay of the psychological and physiological, the mental and physical, exhibiting paradoxical characteristics. These emotions are not only related to the high-intensity work and competition of modern society but also have metaphysical roots, revealing certain residual issues within the soul and life. Burnout is widely captured in modern literature and artworks, becoming a potential possibility for reflecting on nihilism and containing a resilience of resistance. From Pascal and Kierkegaard's reflections on boredom to Heidegger's exploration of boredom as a fundamental mood of "being-towards-death," it is shown that boredom is not entirely equivalent to nihilism but may become an anticipation of new meaning.

Heidegger's Appropriation of Boredom

This section explores in depth Heidegger's appropriation of the mood of boredom and its importance in modernity. Heidegger views moods as the disclosiveness of Dasein, taking precedence over cognition and will, inheriting the Christian tradition's emphasis on affectivity. He regards anxiety and boredom as fundamental moods of being, with profound boredom considered more capable than anxiety of receiving the givenness of beings and heeding the call of Being. Heidegger distinguishes between three forms of boredom, with profound boredom being the condition of possibility for the first two. It confronts individuals with their authentic situation, revealing the origin and abyss of Being—"the nothing." He posits that profound boredom is a latent, positively affirmed possibility that stirs dread within the human heart, enabling individuals to examine and shoulder "the nothing" while overcoming the groundlessness of existence. However, Jean-Luc Marion questions Heidegger's optimism, arguing that Heidegger underestimates the negativity of boredom, suggesting that boredom may cause us to lose interest in the demands of Being and even lead to the dissolution of worldliness itself. Marion further analyzes that boredom is a dual dissolution of the self and the world, suspending Being, whereas true authenticity is the call of "otherwise than being," i.e., the call of God, which can awaken the Dasein immersed in boredom.

Levinas's Reversal: Burnout as a "Fold" Oriented Toward the Other

This section delves into Levinas's philosophical reflections on the phenomenon of burnout, particularly his dialogue with and differences from Heidegger's thought. Levinas views burnout as an ethical phenomenon, emphasizing the individual's sense of fatigue when confronted with their own existence and the importance of overcoming this burnout through interaction with the Other. He critically responds to Heidegger's views on fundamental moods, especially the understanding of "boredom," arguing that fatigue and weariness are the natural state of existence. By analyzing emotions such as "nausea" and "shame," Levinas reveals the individual's sense of bondage and powerlessness in the face of existence, while also employing literary works to express this emotional atmosphere. He proposes the concept of "escape," attempting to redefine time through otherness and sociality, in contrast to Heidegger's "being-towards-death." Levinas's thought holds significant importance for understanding the phenomenon of burnout in contemporary society, particularly as it is further developed and applied in Byung-Chul Han's *The Burnout Society* and *The Expulsion of the Other*, emphasizing the redemptive role of the Other regarding the problem of burnout in modern society.
