The moments we get to know Viola best occur when her double and single gender identities cause friction. She fumbles when speaking about love to Orsino, her object of desire, and states: “I am all the daughters of my father’s house, / And all the brothers too” (2.4.120-1). In attempting to cover up her previous statement, concerning her knowledge about female love, she thus invokes her doubled identity. Several scenes later, Viola invokes her identity again, to rebut Olivia’s love; Viola states: “I am not what I am” (3.1.138). Viola implies here that she is not a man, but a woman, and encompasses a single gender. The moments where Viola must speak for her identity reveal that it is shaped by both Duval’s notions of double and single gender identities, and thus illustrates Greenblatt’s argument that identity forms at the boundaries between categories.
