An ancient legend identifies Demon, Chance, Love and Need as the four gods who preside over the birth of every man. Sooner or later we all need to deal with them. But to face these simultaneously obscure and positive deities means – as Agamben suggests in this new, surprising book – to live one’s life as an adventure. And not in the trivial sense of the term, with lightness and disenchantment, but considering adventure as the most profound experience in our human existence, of which Demon, Chance, Love and Need are but mere masks. Through a fascinating itinerary that unfolds from poems of chivalry to philosophy, from Lancelot to Beatrice, these four deities are ultimately joined by a goddess, the most elusive and mysterious of all: Elpis, Hope, who in Greek mythology remains closed in Pandora’s jar whereas it is here presented as the ultimate symbol of the human adventure on Earth.
