The Feeling of Life Itself: Why Consciousness Is Widespread but Can't Be Computed

Christof Koch argues that consciousness is an intrinsic property of matter identified as Integrated Information Theory (IIT). He locates the origin of subjective experience in the posterior hot zone of the cerebral cortex rather than the prefrontal lobes. Through the lens of Tononi’s mathematical framework, Koch explains that consciousness depends on the causal power of a physical system upon itself. This leads to the conclusion that while many biological organisms possess internal felt experiences, digital computers running software simulations do not, as they lack the necessary causal architecture to generate the feeling of life.

This book serves neuroscientists and engineers interested in the physical boundaries of awareness. Readers gain a technical perspective on why artificial intelligence remains mindless despite sophisticated behavior. By following the distinction between simulating a system and being one, the reader identifies which biological structures support feeling. The text provides a rubric for assessing consciousness in non-verbal patients and animals, replacing philosophical speculation with a quantitative metric for the presence of the soul.
