The topic "Tension in the History of Literature" borrows the concept of physics and opens its eyes for itself. Tension originally refers to the mutual traction existing on both sides of any internal section when an object is pulled.
The history of literature also has such a feature. Some scholars say that writing the history of literature is a kind of power. There is such a tension between restoring historical truth and controlling historical narrative by literary historians. This is also the difference between the theoretical study of literary history and the literary study of specific writers' works. In this sense, the study of literary history seems to have its boundaries, but also has its infinite research space.
Looking forward to reading it!
