Giacomo Leopardi is one of those authors whose texts oscillate on the border between literature and philosophy. It is true that Leopardi does not use traditional forms of philosophical expression, but the fact is that most of the considerations of the Italian thinker are expressed by the simultaneous conduct of two discourses: literary and philosophical. Leopardi experimented almost every form of literary expression, but he went down in history mainly as a poet, who contained a significant part of his highest (...) beliefs in poetry. The practice of philosophizing through poetry is nothing new in literature, and the various connections between literature and philosophy are almost ancient, but the ongoing discussions in the world of Italian critics about the relationship between Leopardi and philosophy suggest that the reflective lyrics of the famous poet from Recanati are an noteworthy case.
