Contemplating one’s own death is a core aspect in the history of Western philosophy. In the modern era, existential philosophy has inherited this tradition and established unique discussions on the concept of “my death,” resting on the premise that this concept is unapproachable via scientific inquiry. Conversely, biological research is essentially conducted within the scope of life phenomena, with death being referred to in the sense of lifespan; thus, death is not among its inherent themes, which automatically excludes the concept of my death from its scope. To establish a dialogue between the two fields, this study questions the widely held premise that my death is unrelated to science and is best examined by philosophy. I consider the movement between continuity and discontinuity as foundational to scientific development, and integrate it with the relationship between the unknown and known. Furthermore, I extend this to the concepts of consciousness and body, and subsequently clarify and define the unknown divisions. Finally, I examine the kinds of unknowns that science confronts to interpret philosophically how an aspect of reproductive theory has unwittingly revealed a completely new dimension of life: my death. Overall, I argue that my death is an essential point of contact between philosophy and biology that reveals the scholarly significance of the unknown.
