mian men idean theriou poikilou kai polykephalou1At the heart of the Platonic Republic, amidst the most examined of philosophic spaces, a purloined letter gazes back unconcealed into the inspecting stare; most efficaciously, under the eyes of centuries of interpretation, the letter operates unnoticed. It relates the whole psycho-political project of the Republic to a figure, which overwhelms the project itself, a figure barely contained under the guise of metaphor. This figure shows itself in the simplicity of something "outlined (like a sign) and memorable (like an image or a tale),"2 which sets discourse in motion. It re-joins the worn-out allegories of the sun (508b-9c), the divided line (509d-13e), the cave (514a-20a), and the closing Myth of Er (614a-21d), which already attest, within the space of the text, a forlorn inner purity and pure interiority of what in the name of logos constitutes itself as knowledge.The hyperbolic figure, which articulates and measures the Republic, is that of the therion, a living thing, a certain kind of zoe, which in the Greek of Plato refers on the one hand to both tame animal and wild beast, while designating on the other, all that is monstrous: Typhon, Hydra, the Satyrs. In turn, therion as monstrosity, appears both as a prodigious, threatening creature, yet also as monstrum, teras, as sign of excessive signification,3 a sign, which doesn't show itself-in the case of tyranny, the capital monstrosity in the Republic, even a tell-tale symptom of a disease that hides itself in order to take effect. The monster hides and manifests itself, announces its secret, while concealing the violence of its conspicuous presence. It operates in the city and in the soul, as it operates across the dialogue and the text that constitute the Republic.Thus, the figure of the therion, beast and monster at once, inscribes itself as a purloined letter, articulating a literary metaphor and a literal metamorphosis, the one as much as the other, the one because of the other. This letter amounts to an open invitation to unfold the theriological figurations in order to examine anew what is truly inceptive at the beginning of political thought. The first insight of this unfolding recognizes in the therion the infinitesimal affinity of beast and monster as well as their infinite non-coincidence. The commerce of the figurations of beast and monster in the figure of the therion is originary and irreducible.4 Ultimately, the thread that joins these theriological instances in the Platonic corpus will have to be followed through, transforming received notions of metaphor and catalyzing a metamorphosis of the history of Platonic thought in order to assess the occidental fate of the polis.The first to follow upon this path is Aristotle, who will reiterate the Platonic dichotomy of a tamed people (demos) and a monstrous mob (ochlos) into a double origin of the political: the "organization of the human community in accordance with the telos of the reasonable being" on the one hand and on the other "as a remedy for the sheer fact of social division."5 This dichotomy, never singular in its refractions, reiterates itself up until and beyond Agamben's opposition of zoe and bios, in an intricate history, the unraveling of which must wait at present. Still, in order to make meaningful what must here remain allusive, namely the perennial return of bio-politics to zoo-politics, to which the Coda of the text returns, the zoe of polis must be traced in the manifold figurations of the Platonic figure of the therion. Revolving around the Republic, the present essay undertakes this examination of Platonic psycho-political theriology.Theriology is necessarily psycho-political: the grand homology of psyche and polis is no less than the structural force articulating the Republic. The first recipient of this homology is once more Aristotle. His valuation of the political over the personal good is founded upon the identity (tauton) of the supreme human good in both. …
