Desire occupies a contested but indispensable position across the depth-psychology corpus, functioning simultaneously as the engine of psychic life and the principal obstacle to liberation. The ancient philosophical tradition, represented by Plato and Aristotle, establishes desire’s structural ambiguity most rigorously: for Plato, desire is a tripartite problem—a force that can align with or subvert rational governance of the soul; for Aristotle, it is the motivational foundation of all animal locomotion, irreducible to intellect alone, and requiring the mediating function of phantasia to become purposive. These classical frameworks reappear, often unacknowledged, throughout later depth-psychological and spiritual writing. Aurobindo reads desire as the cosmic lever of self-affirmation, a divine-life principle that must not be extinguished but transformed from devouring hunger into infinite giving. Easwaran, following the Upanishadic and Gita traditions, insists that desire is raw psychic power—morally neutral in itself, catastrophic or liberating depending on whether will masters it or is mastered by it. Perel relocates desire squarely within erotic relational life, arguing that desire requires distance, otherness, and even transgression to survive domesticity. Lewis grounds desire neurobiologically, connecting it to dopamine dynamics and the contraction of temporal perspective in addiction. Carson, reading Sappho, finds desire constituted by its own incompleteness—a structure of transience and repetition that makes it paradigmatically bittersweet. Across these positions, the unresolved tension is whether desire is to be transformed, redirected, escaped, or simply inhabited—and whether its object is ultimately finite or infinite.
