The reading of Coleridge’s “Frost at Midnight” at the center of this chapter opens up the cognitive and aesthetic stakes of seeing writing. It does so by analyzing the encounter with visible script, an experience that can be understood as a reworking of a previously unrecognized source, the scene of writing in David Hume’s A Treatise of Human Nature, Book 4. Just such an encounter is the activity in play with the figure of the window frost and with the entire poem. Broadly speaking, sentence formation is seen as analogous to frost formation. In this way, the discussion seeks to shift the sensory register of criticism of the poem from its traditional emphasis on the acoustic to a new appreciation of the visible.
