This study argues that heteroglossia should be regarded as the practice of ethics theoretically, based on Mikhail Bakhtin’s perspective of rhetoric. This paper outlines dialectics and utopianism by referring to the necessity
of rejoinder, the limitedness/effectiveness of advocacy, and the strategy of action inherent in the rhetoric of heteroglossia. Furthermore, a possible path is explored for practicing the ethics of heteroglossia by articulating
Bakhtin’s stratifications of language, as implicated in the outer dialogicity of polyphonic novels and Judith Butler’s parodic performance. This study concludes that the ethics of heteroglossia might be embodied by temporary
attachment to social prohibition; hereafter, the compulsory and contingent category of the pregiven cultural norms could be strategically disclosed through the rhetorical act of rhetor furthermore.
