The term ‘Sovereign’ in the depth-psychology and allied humanities corpus occupies a contested, multi-register space. In the political-theoretical stratum—most extensively represented through Arendt scholarship—sovereignty is interrogated as a structural antagonism: internally, it names absolute, monological rule antithetical to republican plurality and constitutional constraint; externally, it designates the independence of states in an anarchic international order. These two faces are held in productive tension, and their attempted separation generates the ‘boomerang effect’ whereby unchecked external sovereign power colonizes domestic republican institutions. In the critical-theory register, Han’s reading of Agamben introduces the figure of the sovereign as the paradoxical double of homo sacer in achievement society, where self-exploitation dissolves the classical sovereign–subject dyad into a single autopoietic violence. In the linguistic-anthropological register, Benveniste traces the Indo-European rex not to domination but to the one who ‘traces the right line,’ a religious-juridical rather than merely political authority. The I Ching commentary tradition, via Wang Bi, deploys the sovereign as a cosmological-ethical exemplar whose rectitude and mean-position validate rulership. Across these registers, sovereignty names the problem of legitimate concentrated power—its genesis, limits, transferability, and psychic internalization.
