This paper explores the ethical potential of performative speeches in Park Sol-moe’s novel Future Walking Practice(2021) to deconstruct universal history through an analysis of the unique manifestations of speech found in the work. The distinctive style of the work is embodied in the unique manner of expression of the narrator-character I. Specifically, contradictory speeches manifest as a form of speech where past and present, present and future are intertwined. The I’s present carries meaning as an alternative possibility that someone from the past might have imagined. This perception of time is evident in the manifestation of speeches where tenses are intermingled, demonstrating a performative ethic that fractures the universality of history based on a linear perception of time. Additionally, Future Walking Practice exhibits the aspect of leaping speeches devoid of determinism. Similar to the characters strolling wherever their feet take them, their leaping speeches are open towards encounters with fortuitous landscapes and realizations, extending towards different times, places, and others. Such leaping speeches demonstrate a performative ethic of openness. Lastly, the paper examines prophetic speeches that preempt the future. In the process of repeatedly imagining different futures, speeches with prophetic tones emerge as expressions of faith in the impending future. I overlays the speeches of those who had hopes for abetter future from a prophetic perspective, demonstrating a transcendent performative ethic.
