Levinas and Dostoevsky’s thoughts on infinite time are inseparable from their ethics. For Levinas, the concept of “infinite time” is the ultimate condition in which subjectivity could prove its truth and goodness. Dostoevsky steadily questioned how one could do good without belief in immortality. Previous studies comparing two authors have focused on the attribution that both preached ‘an asymmetrical relationship with other’, which could realize an infinite time in this world. Therefore, this paper argues that Levinas and Dostoevsky also elaborated on their concept of paternity while deliberating on the relation between ethics and infinity. To analyze the concept of paternity, chapter 4 “Beyond the Face” in Levinas’ “Totality and Infinity” and Dostoevsky’s novel, “The Adolescent” have been chosen. In these works, Levinas and Dostoevsky share a theme of biological family that could be interpreted as a model for conceptualizing the paternity. As Levinas summed up paternity in a sentence ‘I is its son’, this paper tries to illuminate the discourse of two authors regarding the dialectics of the self. In “Totality and Infinity”, Levinas relates the son who I will have through phenomenology of Eros and paternity with my future, which is not a future of the same(du Même). However, this paper is more fixated on finding the concrete illustration of the ‘I’ who can be still ‘I in one’s son(être moi dans son fils)’ in Dostoevsky’s novel, “The Adolescent”. In “The Adolescent”, the father Versilov and his son Arkadii stay as strangers to each other throughout the entire story, thus embodying an asymmetrical relation between I and the future of I. Nevertheless, Arkadii’s notes completed with the strange father’s story illustrates how I can reconcile with the future I, despite the discontinuity of generation.
