Aristotle's statement that the spectator of epideictic rhetoric judges dynamis is problematic because it seems to direct audience judgment towards the ability of the speaker as opposed to the subject-matter of his speech. I argue that, as a reference to the speaker's ability, the remark indexes the peculiar competitive structure in which speeches of praise and blame are conventionally involved. Thus understood, it is essential to Aristotle's taxonomy of genres and helps resolve the dilemma created by naming the genre of praise and blame after a mode of performance, epideixis, compatible with speeches of any formal description

The Helen of Gorgias is designed to provoke the aspiring speaker to consider his relationship with society as a whole. The speech's extreme claims regarding the power of logos reflect simplistic ideas about speaker-audience relations current among Gorgias' target audience, ideas reflected in an interpretive stance towards model speeches that privileges method over truth. The Helen pretends to encourage this conception of logos and interpretive stance in order to expose the intense desire and naïve credulity that drive a coolly technical appraisal of model speeches. The Helen thus manifests, with a playfulness suited to its liminal position, a concern for the ethical and social formation of those who might accept the invitation to study logos.
