Abstract

This commentary analyzes Yongho Choi’s five-axis model (object, mode, depth, frame, biological constraint) of linguistic understanding, which moves beyond traditional philosophical accounts. The model’s success in reframing understanding within a multidimensional participation space, thereby productively explaining both the AI debate and clinical dissociations, is acknowledged. The focus is placed specifically on the “Threshold Conditions” (Sect. 5.6), which carry the model’s normative force and exclusionary claim. Two critical thresholds—“Normative Repair” and “Embodied Anchoring”—are examined in depth, questioning the ambiguity of their sufficiency status: Are these thresholds empirical benchmarks, normative standards, or ontological conditions? It is argued that Normative Repair must distinguish between reason-responsive participation and causal simulation, while Embodied Anchoring should point not merely to a biological constraint but to the existential-vulnerable source of understanding (Heidegger, Merleau-Ponty). In conclusion, a call is made for further dialogue to develop the model’s concept of “dynamic integration” from a descriptive mapping towards a constitutive principle, in light of the phenomenological and hermeneutic traditions the model now incorporates.
