"A revelatory new theory of consciousness that returns emotions to the center of mental life. For Mark Solms, one of the boldest thinkers in contemporary neuroscience, discovering how consciousness comes about has been a lifetime's quest. Scientists consider it the "hard problem" because it seems an impossible task to understand why we feel a subjective sense of self and how it arises in the brain. Venturing into the elementary physics of life, Solms has now arrived at an astonishing answer. In The Hidden Spring, he brings forward his discovery in accessible language and graspable analogies. Solms is a frank and fearless guide on an extraordinary voyage from the dawn of neuropsychology and psychoanalysis to the cutting edge of contemporary neuroscience, adhering to the medically provable. But he goes beyond other neuroscientists by paying close attention to the subjective experiences of hundreds of neurological patients, many of whom he treated, whose uncanny conversations expose much about the brain's obscure reaches. Most importantly, you will be able to recognize the workings of your own mind for what they really are, including every stray thought, pulse of emotion, and shift of attention. The Hidden Spring will profoundly alter your understanding of your own subjective experience"--
A glimpse inside

Solms argues that consciousness emerges primarily from our feelings, not our thoughts. Unlike traditional views that place higher cognitive functions at the center, he draws on neuroscience and clinical cases to show that the core of consciousness lies in affect—our basic, bodily feelings. These primal emotions, generated deep within the brainstem, are what make subjective experience possible. This reframing has profound implications for understanding mental life, mental illness, and even artificial intelligence.
Contrary to the popular belief that the cortex is the seat of consciousness, Solms presents evidence that the brainstem—an ancient, evolutionarily conserved structure—is crucial. Patients with severe cortical damage can still display signs of consciousness if their brainstem is intact, while damage to the brainstem abolishes consciousness entirely. This challenges the 'higher brain equals higher mind' assumption and redirects the search for consciousness’s origins to the neural machinery governing basic needs and emotions.
