The concept of arete — excellence, virtue, the fullest realization of a being’s defining capacities — commands sustained and contested attention across the depth-psychology corpus, appearing wherever scholars interrogate the relationship between inner character and outward achievement in Greek thought. Sullivan’s comprehensive survey of early Greek psychological ideas traces arete from its probable etymological root in ‘thriving’ or ‘flourishing’ through Homer’s heroic code, Pindar’s doctrine of inborn excellences, Theognis’s aristocratic ethics, and Heraclitus’s startling reduction of arete to intellectual self-knowledge — sophronein. Adkins, working from a sociological and semantic vantage, pursues arete as a site of ideological contest: a term whose competitive valence — commending courage, birth, wealth, and results over intention — perpetually resists assimilation into cooperative moral categories such as dikaiosune. The central tension the corpus exposes is precisely this: whether arete names an achieved social and martial superiority judged by outcomes, or an inner excellence of character accessible through nature, training, or rational self-possession. Aristotle’s reformulation — distinguishing ‘natural’ arete from its completed, intelligence-directed form — and Plato’s identification of dikaiosune as the human arete represent the philosophical apex of this struggle. The term thus functions in the corpus as a diagnostic instrument for the entire developmental arc of Greek ethical psychology.
