[Objective] The purpose of this study is to investigate how interminable mourning by enduring the connection with the deceased becomes an embarkment into a new life by comparing and examining the view on death in the Korean traditional funeral rituals and the mourning theory of Derrida. [Contents] To accomplish this purpose, the study will discuss two different aspects: First, the Korean view on death was found from Korean traditional funeral rites revealed in ‘Chohon’ and ‘Kokdu’ decorated on the bier. Second, through Derrida’s theory of mourning which is interminable, inconsolable, and irreconcilable, it is clarified that death is not the starting point of forgetting the deceased, but the point when mourning begins. The deceased should be loved more and the promise with the object should be more precious. The point where the Korean traditional view on death and Derrida’s theory of mourning, which coexist with the living in the relationship with descendants even after death, is discussed in depth. A continuing bond with the deceased through memory is a part that can soothe the grievous sorrow caused by loss and becomes the basis for growth of the mourner. [Conclusions] As a result, grief of loss goes through a process of meaning reconstruction through sufficient mourning. The traditional Korean view on death and Derrida's interminable mourning confirm that death is not the negation of life but the affirmation of it.
