Tracing its provenance through the biological notions of phylogeny and "organic memory" that fueled early psychoanalysis, back into idealism, nature philosophy, and romanticism, and across multiform encounters between philosophy, psychology, biology, and geology, Thomas Moynihan reveals the historical continuity of spinal catastrophism. From psychoanalysis and myth to geology and neuroanatomy, from bioanalysis to chronopathy, from spinal colonies of proto-minds to the retroparasitism of the CNS, from "railway spine" to Elizabeth Taylor's lost gill-slits, this extravagantly comprehensive philosophical adventure uses the spinal cord as a guiding thread to rediscover forgotten pathways in modern thought.
Moynihan demonstrates that, far from being an fanciful notion rendered obsolete by advances in biology, spinal catastrophism dramatizes fundamental philosophical problematics of time, identity, continuity, and the transcendental that remain central to any attempt to reconcile human experience with natural history.
