The term ‘Bud’ appears in the depth-psychology corpus in three distinct registers that, taken together, reveal the breadth of the library’s concerns. First and most extensively, ‘Bud’ functions as the proper name of Bud Osborn — poet, addict, and community organizer — in Johann Hari’s Chasing the Scream, where it anchors a sustained meditation on addiction, social death, collective trauma, and the redemptive power of solidarity. Here ‘Bud’ is less a psychological category than an incarnate case study in what Hari frames as the social determinants of addiction and recovery. Second, Jung’s Symbols of Transformation invokes the bud as an archetypal image — the state of being ‘guarded in modest bud’ — linking latency, maternal protection, and the pre-individuated psyche to solar mythology and the birth of consciousness. This botanical-symbolic usage connects Simondon’s parallel treatment of budding as a biological mode of reproduction involving undifferentiated, proliferating elements. Third, ‘Bud’ appears as the familiar name of neurobiologist A.D. (Bud) Craig, whose work on interoception and the insular cortex is represented in the corpus. The convergence of these three registers — social-traumatic, archetypal-symbolic, and neuroscientific — makes ‘Bud’ a useful index of the library’s interdisciplinary range, even as each usage demands its own interpretive framework.
