In the mid-seventeenth century, John Milton was a successful poet and political activist. He wrote scathing pamphlets against corruption in the Anglican Church and its ties to King Charles. In Milton’s day Puritanism meant having politically radical views. And at one point Milton was actually jailed for recording them on paper. Paradise Lost, as much as anything, is a series of arguments put forth by the characters, which in turn ultimately expresses Milton’s personal truth. It is, in that sense, a Puritanical work.
