A philosopher with an encyclopaedic culture, Giacomo Leopardi (1798-1837) is also the great poet of the human condition and of memory. A child prodigy educated according to strict religious principles, this erudite man, along with Dante, entered the pantheon of Italian writers. In accordance with the iconoclastic will of the “Folds” this selection of letters shows another face of Leopardi. The man too often remembered as a pessimist appears here as a deep connoisseur of the human soul, cultivating an ambitious idea of happiness.
