Quote from : The Routledge History of Literature in English: Britain and Ireland Book

John Milton has, since his own lifetime, always been one of the major figures in English literature, but his reputation has changed constantly. He has been seen as a political opportunist, an advocate of 'immorality' (he wrote in favour of divorce and married three times), an over-serious classicist, and an arrogant believer in his own greatness as a poet. He was all these things. But, above all, Milton's was the last great liberal intelligence of the English Renaissance. The values expressed in all his works are the values of tolerance, freedom and self-determination, expressed by Shakespeare, Hooker and Donne. The basis of his aesthetic studies was classical, but the modernity of his intellectual interests can be seen in the fact that he went to Italy (in the late 1630s) where he met the astronomer Galileo, who had been condemned as a heretic by the Catholic church for saying the earth moved around the sun.
