Neurotic symptoms occupy a foundational position across the depth-psychology corpus, serving simultaneously as clinical phenomena, hermeneutic objects, and windows into the structure of the unconscious. Freud’s formulation — that symptoms, like dreams and parapraxes, possess determinate meaning and are causally linked to the patient’s life history — establishes the interpretive programme that virtually every subsequent theorist inherits, contests, or refines. For Freud, symptoms arise at the intersection of repressed wish and defensive counter-force, expressing through somatic or behavioral displacement what cannot be consciously tolerated. Abraham extends this framework developmentally, treating symptoms as products of libidinal regression and linking character change to the same psycho-sexual mechanics. Rank situates symptoms within the primal trauma of birth, while Jung decisively reframes them: where symptoms are present, unconscious energy has accumulated dangerously, but the symptom also carries prospective, not merely regressive, significance. Horney’s neo-analytic perspective shifts emphasis from drive-defense dynamics to the distortions of self-realization imposed by the pride system and neurotic solutions. Jung’s associate Hall distills neurosis as ‘the psyche working against itself.’ Across these voices, persistent tensions recur: is the symptom primarily a residue of past trauma or a signal of present existential impasse? Does it demand reduction to its causal origins or amplification toward its teleological meaning? These questions give the term its enduring theoretical vitality.
