This essay offers an exegesis and critique of the moment of community formation in Agamben’s Homo Sacer Project. In The Sacrament of Language, Agamben searches for the site of a non-sovereign community founded upon the oath [horkos, sacramentum]: an ancient institution of language that produces and guarantees the connection between speech and the order of things by calling the god as a witness to the speaker’s fidelity. I argue that Agamben’s account ultimately falls short of subverting sovereignty, however, because the (...) sacramentum derives its power, at a fundamental level, from the ‘monothetic’ structure of truth—what Agamben calls ‘the name of God’ [il nome di Dio]. I propose we may yet salvage the oath as a means of subverting sovereignty, however, if we reconsider it in the context of polytheism, where the names of the gods [i nomi degli dei] can be many, while remaining powerful. First, through a reading of Aeschylus’ Eumenides, I argue that the Greeks understood the oath to function even where truth and falsity were inherently undecidable. Second, I argue that if we separate the truth and power functions interwoven in the sacramentum, we find a second formula, the decisory oath, which can be taken in order to produce a community even in the absence of one sovereign truth. As a kind of magical speech, the decisory oath provides the limit conditions for the possibility of distinguishing true from false in the sacramentum, and thus founds it. (shrink)
