The term ‘Good’ occupies a contested and multiply-valenced position across the depth-psychology corpus, ranging from its Neoplatonic identification with the supreme metaphysical principle—The One, which ‘radiates Beauty before it’ in Plotinus—to its Stoic articulation as the perfection of rational nature, to Nietzsche’s genealogical demolition of its apparent self-evidence. Plotinus situates The Good beyond Intellectual-Principle itself, as the fountain from which beauty and being alike proceed, a position that finds resonance in Augustine’s insistence that all things are good insofar as they exist, and that evil is merely privatio boni. Jung takes sharp critical aim at precisely this Augustinian-Thomistic privatio doctrine, arguing that its relegation of evil to a ‘mere diminution of good’ fails to account for the empirical reality of psychic destruction. The Stoics, by contrast, treat the good as the singular object appropriate to rational human nature, distinct in kind from ‘preferred indifferents,’ and characterize all goods as equal and complete. Plato’s dialogues stage the founding aporia: whether the good is identical with pleasure, with knowledge, with the kalon, or with something irreducible to any of these. Nietzsche historicizes all such claims, tracing ‘good and evil’ to power relations among ruling and subjected groups. The term is thus simultaneously a metaphysical apex, an ethical criterion, a psychological reality, and a genealogical artifact.
