Modernity changes with time

“The modern work is condemned to become dated unless, by achieving the status of a classic, it manages to free itself from the fluctuations of taste and critical opinion… Literarily speaking, a classic is a work that rises above competition and so escapes the bidding of time. Only in this way can a modern work be rescued from aging, by being declared timeless and immortal. The classic incarnates literary legitimacy itself, which is to say what is recognized as constituting Literature; what, in serving as a unit of measure, supplies the basis for determining the limits of that which is considered to be literary.”

Casanova, Pascale. “The World Republic of Letters”. transl. M. B. Devoise. Harvard University Press, Cambridge, Massachusetts, 1999. pp. 92.

Casanova seems to be suggesting that what it means to be a truly modern work is constantly changing with those writing in different styles and coming up with the “most recent innovations in form and technique”; that is unless it is great enough to reach the status of a classic. From my understanding, Casanova is attempting to describe a modern work with a greater focus on the word “modern” which attempts to constantly grasp at the present while claiming its legitimacy as literature only if it were great enough to become a classic.
