question: What ideas did this Italian philosopher, poet, essayist, and philologist, who wrote the poem L'infinito, come in touch with while living in a secluded town in the conservative Papal States?
answer: Enlightenment
context: Title: Armistice of Bologna
  Passage: The Armistice of Bologna was a treaty signed between the Papal States and the French First Republic on 23 June 1796.  It resulted in a ceasefire between the two parties that was intended to last until a permanent peace treaty could be signed (the 1797 Treaty of Tolentino).  The terms of the armistice included the payment of 15 million livres in cash in addition to goods and works of art to the French and significant territorial reductions.  A temporary Austrian victory against the French at the Siege of Mantua persuaded Pope Pius VI to renounce the armistice in September 1796.  The French subsequently invaded the Papal States and enforced the terms of the armistice.
  Title: L'infinito
  Passage: "L'infinito" (] ; English: The Infinite ) is a poem written by Giacomo Leopardi probably in the autumn of 1819.  The poem is a product of Leopardi's yearning to travel beyond his restrictive home town of Recanati and experience more of the world which he had studied.  It is widely known within Italy.
  Title: Giacomo Leopardi
  Passage: Giacomo Taldegardo Francesco di Sales Saverio Pietro Leopardi (] ; 29 June 1798 – 14 June 1837) was an Italian philosopher, poet, essayist, and philologist.  He is widely seen as one of the most radical and challenging thinkers of the 19th century.  Although he lived in a secluded town in the conservative Papal States, he came in touch with the main ideas of the Enlightenment, and through his own literary evolution, created a remarkable and renowned poetic work, related to the Romantic era.  The strongly lyrical quality of his poetry made him a central figure on the European and international literary and cultural landscape.
