This chapter makes a case for the letter to be considered as a literary-cultural form that offers crucial insights into the creation and sustenance of narrative universes of blindness. While all forms of writing presuppose readership, the letter remains distinct in its orientation towards a particular addressee; therefore, self-other dynamic wields greater influence on epistolary narrativisation. The chapter develops two argumentative threads. First, in reading letters written by John Milton, Priscilla Pointon, Helen De Kroyft, and Helen Keller, I argue that rather than acting as a constraint, the intersubjective dynamic enables the blind writer to narrativise the self in ways subtly and overtly challenge dominant conceptions of blindness prevalent at a given time and place. While Milton builds a counter-narrative in response to offers to cure his impairment using poetic and mythological language, Pointon writes verse epistles to defend herself from attempts at belittling her literary endeavour; De Kroyft employs sentimental vocabulary to posit blindness as a regenerative condition; and Keller finds the letter a useful tool to articulate her subjectivity. Second, in referring to Georgina Kleege and Stephen Kuusisto’s collections of letters, I contend that the self-other dynamic animates the ostensibly public epistolary subgenre of the open letter. Kleege’s use of the open letter to renarrativise Keller’s life story simultaneously generates self-narrativisation that lends credibility to her endeavour. Kuusisto, rather than making renarrativisation the central aspect of his verse letters, treats Borges as an empathic copresence in his attempt at challenging the definitional bind that sighted culture has over blindness.
