Reversal occupies a conceptually rich and structurally diverse position across the depth-psychology corpus. In Freud, it names a fundamental mechanism of the dreamwork: the inversion of relations—spatial, temporal, affective, or causal—whereby the latent content of dream-thoughts appears in the manifest dream as its contrary. This ‘just the reverse’ logic demands interpretive correction before the dream yields its meaning. Bion extends the concept into object-relations territory through ‘reversal of alpha-function,’ a pathological turning-back of the mind’s meaning-making capacity: instead of transforming raw sense-impressions into usable mental elements, the function operates in reverse, dismantling the contact-barrier and producing the beta-screen. Victor Turner deploys reversal as a ritual-structural category—‘status reversal’—wherein socially inferior groups temporarily assume dominance over their superiors within bounded liminal time, thereby paradoxically reaffirming the very structure they appear to subvert. The Taoist tradition, as rendered in the I Ching commentaries of Liu Yiming, treats reversal as the foundational practice of interior cultivation: the ‘path of reversal of conditioning’ opposes the soul’s natural drift toward outer accord, instead directing illumination inward. LeDoux employs the term clinically to describe the undoing of extinction learning. Across these traditions, reversal signals a hinge-point—whether therapeutic, cosmological, ritual, or oneiric—at which polarity is inverted, process redirected, and hidden structure exposed.
