Core claims

The Theaetetus is not a failed attempt to define knowledge but the most rigorous dramatization in antiquity of how the psyche encounters its own limits — making it the foundational text for understanding aporia as a psychotherapeutic event, not merely a philosophical one.
Socrates’ maieutic method, as elaborated in the Theaetetus, is the first clinical protocol for depth work: the midwife does not implant content but creates the relational container in which the soul’s own latent structures can be born, miscarried, or recognized as “false phantoms” — a procedure Jung explicitly acknowledged as the ancestor of analysis.
The dialogue’s systematic dismantling of perception, true judgment, and true judgment with an account as definitions of knowledge prefigures the depth psychological insight that the ego cannot know the Self through any of its own cognitive functions — only through the transformative encounter with what exceeds them.

How does Socrates’ description of maieutic method in the Theaetetus compare to Edinger’s account of coagulatio in The Mystery of the Coniunctio — specifically, is aporia an alchemical operation performed on the intellect?
Peterson argues in The Middle Voice that Plato’s Republic performs a “catastrophic misreading” that severs thumos from nous. Does the Theaetetus, written in the same period, resist or participate in that severance — and what does this tell us about the tension within Plato’s own psychological vision?
Hillman’s concept of the “errant cause” from the Timaeus describes a necessity that Reason cannot control. How does this map onto the Theaetetus’ aporetic ending — is the dialogue’s refusal to define knowledge an instance of ananke breaking into philosophical discourse?
