Blake's Night Thoughts discusses Blake as a poet and artist of night, considering night through graveyard poetry and Young in the eighteenth-century, urbanism in the nineteenth and Levinas and Blanchot's writings in the twentieth. Taking 'night' as the breakdown of rational progressive thought and of thought based on concepts of identity, the book reads the lyric poetry, some Prophetic works, including a chapter on The Four Zoas , the illustrations to Young, and Dante, and look's at Blake's writing of madness.
