Symbolic language occupies a contested but foundational position across the depth-psychology corpus, where it designates not merely a mode of expression but the constitutive medium through which psychic life becomes intelligible. Jung establishes the paradigmatic claim: dream-images must be understood symbolically rather than literally, and this principle ramifies throughout his entire metapsychology—from the collective unconscious and archetypes to alchemy and the transcendent function. For Jung, symbolic language is the native tongue of the unconscious, irreducible to sign or allegory. Lacan, approaching from structural linguistics, reformulates this axiom structurally: the unconscious is itself organized like a language, and psychoanalysis is founded on a theory of the symbol—a position Benveniste complicates by insisting that language is not merely symbolic but that all symbolism realizes itself necessarily within a particular langue. Von Franz, reading alchemical texts, charts the historical degeneration from living symbolic language into mere allegory, marking a loss of genuine symbolic experience. McGilchrist adds a neurological dimension, arguing that the right hemisphere apprehends symbolic complexity which the left hemisphere’s drive toward precision can only flatten. The central tension running through this literature is between symbolic language as a generative, multi-valent medium pointing toward what cannot be said directly, and the reductive impulse—whether clinical, logical, or allegorical—to domesticate it into transparent sign.
