Key Chapters

Allow me now to introduce ‘A’, the aesthete. He is not a moralizer nor a cynic, but a connoisseur of life’s possibilities. For him, existence is an art form, a series of moments to be savored, each unique and shimmering before vanishing. When I constructed A’s world, I wished to show how alluring the aesthetic mode can appear. A lives for the singular experience—for novelty, beauty, transitory delight. His reflections wander from essays on music to intricate notes on boredom and seduction, revealing a consciousness refined to the point of paralysis. In his thought, immediacy becomes the highest ideal: reality should please the senses and imagination, not burden the soul with duty.

A’s philosophy centers around the avoidance of boredom. He sees boredom as life’s greatest enemy. To escape it, he cultivates ingenious strategies: varying one’s experiences, rotating interests, approaching existence as a game of renewal. On the surface, this may sound liberating. But beneath it lies deep anxiety—the fear of repetition, the dread that life’s meaning might collapse once novelty fades. I wanted readers to feel that tension. The aesthetic life may seem full, but it is often hollow. It lacks continuity and commitment, because it rejects the seriousness of choice. A lives freely, but his freedom is merely the freedom of an unanchored spirit drifting between impressions.

In A’s essay on the rotation method, he outlines a philosophy of constant transformation. To him, boredom is the root of all evil; it reveals the emptiness of existence when novelty disappears. The rotation method serves to keep life perpetually interesting—changing friends, environments, habits—to prevent the dullness of repetition. A likens life to a crop that needs rotation to remain fertile. His art of living depends on avoiding deep engagement, preserving the possibility of fresh pleasure each day.

I constructed this method as both seductive and tragic. The aesthete's technique seems clever—it suggests mastery over experience—but it finally exposes itself as a flight from reality. The rotation method denies the permanence of meaning. Every relationship, every desire, every art form is reduced to temporary amusement. Life becomes an endless performance in which authenticity withers. Through this irony, I wanted the reader to perceive the cost of aesthetic freedom: when everything is play, nothing truly matters. A’s rotation method thus becomes not a celebration of living but a confession of despair. The aesthete lives in avoidance, unable to face the weight of selfhood. This conflict between perpetual novelty and inner emptiness forms the groundwork for the transformation I later advocate in the ethical papers.
