In "Giving an Account of Oneself", Butler develops an ethics based on the opacity of the subject to itself; in other words, the limits of self-knowledge. Primarily borrowing from Theodor Adorno, Michel Foucault, Friedrich Nietzsche, Jean Laplanche, Adriana Cavarero and Emmanuel Levinas, Butler develops a theory of the formation of the subject. Butler theorizes the subject in relation to the social – a community of others and their norms – which is beyond the control of the subject it forms, as precisely the very condition of that subject's formation, the resources by which the subject becomes recognizably human, a grammatical "I", in the first place.
