""Nightwalking is, in both the physical and the moral meanings of the term, deviant. At night, in other words, the idea of wandering cannot be dissociated from the idea of erring - wanderring. This elision or semantic slurring is present in the final lines of John Milton's Paradise Lost (1667), where the poet offers a glimpse, for perpetuity, of Adam and Eve, after their expulsion from Paradise, entering the post-lapsarian world on foot: 'They, hand in hand, with wandering steps and slow, / Through Eden took their solitary way.' Wandering steps. In a double sense, Adam and Eve are errant: at once itinerant and aberrant. They are condemned to a life of ceaseless, restless sinfulness. ""--
