The difficulties inherent to any analysis of the concept of “modernity” have been frequently emphasised: irregular and approximative semantics, pushed to the limit of totally meaningless, and harmless convention; constant tautology and instability; a whole succession of oppositions, followed by inevitable shifts of meaning and terminological errors; in a word, an endemic and periodically verified crisis. For all these reasons, “modernity” defines (this, however, is only a manner of speaking) one of the most paradoxical of literary ideas: the more widespread it becomes, the more it lacks clarity, the more it grows blurred. And yet—for the paradox to be complete—the phenomenon is clearly inevitable: in one form or another modernity emerges with every important mutation or revolution of literary thinking. Either partially or totally, and also within the framework of new theoretical syntheses, it accompanies or redefines all the decisive stages of European aesthetics. As a real framework concept, “modernity” tends to associate, crystalise or reformulate—with regard to “what is new”—all the essential transformations of literary consciousness. It embraces the complete cycle of the ideal moments of creation and, implicitly, of literature: from the negation of old-style creation, codified and dogma-ridden, to the affirmation of new-style creation, made liberal, and freed from all aesthetic constraint. Modernity breaks a tradition, it disputes the conservative order of art and literature, with a view to instituting and installing its own tradition—this is a cyclical situation, which has perhaps been inadequately discussed. In a similar light, modernity is devoid of all precise chronological determination and becomes a constant which, in the various historical phases and on different semantic levels, expresses the inner movement of literature. This immanent dialectic of the history of literary thought goes through certain essential moments: one day, perhaps, there will come a time when the task of putting these moments in a pattern will be assured of scoring a success.
