Dionysodorus enters the depth-psychology corpus almost exclusively through Plato's Euthydemus, where he figures as the more aggressive of two sophist brothers whose eristic virtuosity Plato deploys as a sustained caricature of philosophy perverted. Within the Euthydemus passages, Dionysodorus functions as the dialectical foil to Socrates: where Socrates pursues genuine self-knowledge, Dionysodorus weaponizes language, collapsing distinctions between truth and falsity, being and non-being, speaking and doing, in order to produce aporia rather than insight. The corpus treats him not as an individual of psychological depth but as a symptomatic figure — the embodiment of what happens when the eros for wisdom curdles into the will to defeat. Kerényi's Dionysos index registers 'Dionysodoros' as a passing name-entry in proximity to discussions of Dionysian nomenclature and cult epithets, suggesting an ambient scholarly awareness of the name's theophoric resonance without substantive mythological elaboration. The tension the corpus exposes is structural: Dionysodorus enacts a grotesque parody of Socratic method, using the forms of philosophical questioning to annihilate philosophical content. For depth psychology, attentive to the shadow dimension of logos, this figure marks the point at which dialectic becomes its own undoing — a cautionary archetype of intellect unmoored from soul.
if Dionysodorus says anything, he says what is true and what is. Yes, Euthydemus, said Ctesippus; but he speaks of things in a certain way and manner, and not as they really are.
This passage presents Dionysodorus's central sophistic gambit — the collapse of the distinction between saying truly and saying as things are — which Socrates and Ctesippus together expose as evasion masquerading as proof.

And are you such an old fool, Socrates, rejoined Dionysodorus, that you bring up now what I said at first — and if I had said anything last year, I suppose that you would bring that up too — but are non-plussed at the words which I have just uttered?
Dionysodorus here performs the sophist's characteristic maneuver of dismissing Socratic consistency as naivety, deploying temporal discontinuity to escape accountability for his own prior claims.

the two brothers Euthydemus and Dionysodorus came in, and several others with them, whom I believe to be their disciples, and they walked about in the covered court.
The scene-setting passage establishes Dionysodorus as Euthydemus's co-equal partner in the eristic display, arriving with disciples and occupying the Lyceum in deliberate parallel to Socratic teaching.

Whichever he answers, said Dionysodorus, leaning forward so as to catch my ear, his face beaming with laughter, I prophesy that he will be refuted, Socrates.
Dionysodorus reveals the anti-philosophical nature of eristic: refutation is predetermined regardless of content, exposing the procedure as theatrical domination rather than genuine inquiry.

Neither and both, said Dionysodorus, quickly interposing; I am sure that you will be 'non-plussed' at that answer.
Dionysodorus's rapid interjection of a paradoxical answer to a question about silence and speech demonstrates the eristic tactic of producing logical paralysis through the assertion of contradictories.

There is much, indeed, to admire in your words, Euthydemus and Dionysodorus, but there is nothing that I admire more than your magnanimous disregard of any o
Socrates' ironic encomium of the brothers underscores Plato's satirical intent: the praise of their 'magnanimous disregard' inverts genuine philosophical virtue into its sophistic counterfeit.

persons whom Plato ridicules in the epilogue to the Euthydemus are of this class. They occupy a border-ground between philosophy and politics... Plato quaintly describes them as making two good things, philosophy and politics, a little worse by perverting the objects of both.
The editorial apparatus frames Dionysodorus and his brother as representatives of a broader class of philosophical perverts whose border-dwelling between disciplines corrupts both.

It is this stage of philosophy which Plato satirises in the Euthydemus. The fallacies which are noted by him appear trifling to us now, but they were not trifling in the age before logic.
The introduction contextualizes the sophistic methods of Dionysodorus historically, arguing that Plato's satire addresses a genuine epistemological crisis in pre-logical Greek thought.

The Euthydemus is, of all the Dialogues of Plato, that in which he approaches most nearly to the comic poet. The mirth is broader, the irony more sustained, the contrast between Socrates and the two Sophists, although veiled, penetrates deeper than in any other of his writings.
The prefatory assessment of the Euthydemus as Plato's most comic dialogue positions Dionysodorus's role within a deliberately theatrical and satirical frame rather than a straightforwardly philosophical one.
