Within the depth-psychology corpus, laughter occupies a surprisingly contested position, oscillating between somatic liberation and spiritual transgression, between archetype and pathology. Hillman’s archetypal readings are the most sustained: he locates laughter at the very origin of fertility in the Isaac narrative, arguing that monotheism’s suppression of genuine laughter constitutes a ‘laughless biblical superego’ whose cure is the comic redemption of literalism. Miller extends this toward an archetypal psychology of humor, insisting that smile and laughter are imaginal patterns before they are overt behaviors, and that depth analysis demands they be granted archetypal amplification. Panksepp grounds laughter in evolutionary neuroscience, tracing it to subcortical PLAY circuits shared across species, while Dayton recasts it as somatic medicine—reducing stress hormones, conditioning the cardiovascular system, elevating immune function. The ascetic tradition, represented by Hausherr’s patristic survey, regards unguarded laughter as a spiritual vice, a symptom of pride releasing the demonic; Hillman explicitly names this suppressive legacy. Hillman’s Freud, channeled through A Blue Fire, reads laughter as the breakthrough of the repressed—wit whose soul is repression. Trungpa introduces a Tibetan dimension: sudden laughter as the vehicle of awakening, the ironic perception of polarity cracking open enlightenment. Taken together, the corpus situates laughter at the intersection of neurobiology, archetypal imagination, spiritual discipline, and therapeutic redemption.
