The study deals with Dylan Thomas's concept of death. The essence of his rebellion against it lurks in his constant refusual to admit to it. There is neither rest nor peace in his vision of death; there is rather an alleluia of all the earth's potential energy which is presented in a pattern of mystical and surrealistic images. Therefore, his philosophy of death is a paradoxical one. It is a mixture of both mystical reflection and scientific or material facts to reach an eternal world. Dylan Thomas's philosophy of death is a paradoxical one. It is a mixture of both mystical reflection and scientific facts to reach an eternal world. Accordingly, one should not expect that poetry to Dylan Thomas simply means a garment with which one dresses one's emotion in order to create a song. To him the relationship between poetry and emotion is similar to that relationship between body and soul as one being, just as a man himself is created. His poetry becomes then a constnt endeavor to explore the scientific and the mystical eternity of the soul and its connection with the external materialistic milieu (i.e. th body and nature). Hence the essence of Thomas's rebellion against death as a final station of the journey of man in life emerges as a constant debate of refusal, protesting and raging to admit to death or sometimes it is a cry of revulsion against dying.
