Within the depth-psychology corpus, ‘Levine’ names at least two distinct and consequential figures whose contributions orbit very different theoretical territories. The more extensively represented is Peter A. Levine, Ph.D., founder of Somatic Experiencing (SE), whose works—chiefly Waking the Tiger (1997) and In an Unspoken Voice (2010)—argue that trauma is fundamentally a physiological phenomenon rooted in the autonomic nervous system and the freeze-discharge cycle observable across mammalian species. Levine’s thesis that post-traumatic suffering constitutes an injury rather than a disorder, and that healing proceeds through titrated somatic awareness rather than cathartic abreaction, places him in productive tension with both classical psychoanalytic and cognitive-behavioral traditions. His work is frequently cited by Pat Ogden’s sensorimotor school, by Allan Schore’s affect-regulation framework, and by the Polyvagal-inflected literature. A second figure, Amir Levine (with Rachel Heller), appears in the corpus as co-author of Attached (2010), an application of adult attachment theory to intimate relationships. More peripheral Levine references—J. Levine in neurobiological research, S. Levine in HPA-axis studies, Amy-Jill Levine in New Testament scholarship—surface in bibliographic apparatus. The convergence point for the corpus, however, is unmistakably Peter Levine, whose somatic turn has become a foundational reference point for body-centered approaches to trauma and its treatment.
