I study French literature and I want to carry out a research in comparative literature which compares two books written by soldiers of the World War(One of them by a French soldier and the other one by a German soldier).
My problem is that I cannot find a good method for this subject. Books concerning comparative literature, talk about the influence of one book on another book( the theory of intertextuality), but my research is not about the influence, and I want to compare two different points of view about a phenomenon.
This is a master thesis and I have enough space for comparing many aspects such as characters,Narrative point of view,theme, etc. I want to know the method/theory with which I should do that. The main problem about which I want to talk is to show how the soldiers of the two fronts thought about the war(WWI) . I hope that my question is clear.
