In Prometheus Unbound Shelley presented a solution about the problem of suffering men in Prometheus who tried to save the world from the tyrant Jupiter. Prometheus is a kind of Shelley’s surrogate for his Utopian Idealism. Shelley also focused love to realize his ideal world founded on freedom and social justice. Liberation of Prometheus is connected with the changing mind of Shelley: his hate was removed by the love of Asia. Shelley wished all men free and happy and was sure that real freedom can be obtained not by the external revolution but by the internal mind revolution. Prometheus recognized human virtue can be contorted into self-destructive one if it was not associated with love. Through his unification with Asia, Prometheus could liberate himself and realize his revolution to the ideal world. In this long poem, Love is an eternal value in the changing world and the most valuable virtue and a power to restore life. When a man recovers the power of love and strengthens morality, he becomes a good man who can realize human freedom and social justice. Unbound Prometheus tells us that ‘freedom’ and ‘love’ can make human life richer and happier.
