Neuroscience has made significant progress in understanding the brain, but the nature of consciousness remains elusive. At the same time, recent spectacular advancements in artificial intelligence promise the prospect of machines attaining human-like cognitive abilities. At the center of both systems is a fundamental dance of stimuli and response, requiring a profound comprehension of the physical environment. Thus, quantum mechanics and general relativity can be applied to the mysteries of human behavior, such as the difficulty of predicting, controlling, or retracing our thoughts. This landmark book explores the nature of consciousness through the lens of physics rather than neuroscience. Physics has been an explanatory force in diverse phenomena, and it can offer an entirely new vision of consciousness as an irreducible entity, similar to particles, the fundamental units of energy or matter. The fermionic mind hypothesis emerges as a tour-de-force synthesis and framework for understanding consciousness, reimagined as the elemental unit of intellect. It highlights particle organization, a fundamental structure that cannot be understood as the sum of its parts, as the essential analogy between fermions and consciousness. The book presents an engaging scientific narrative that explores some of humanity's oldest and most challenging questions. What is consciousness? What are emotions? How can a physical brain create subjective experience? Do we have free will? Engaging and penetrating, Emotional Reasoning represents a groundbreaking perspective that will surprise you at every turn. It will enhance your confidence through understanding yourself and your place in the cosmic order. Beyond neuroscience, the book holds profound implications for artificial intelligence research. It reveals the intricate link between consciousness and the physical universe, echoing the philosophical insight of theoretical physicist John Wheeler: "The physical world is, in some deep sense, tied to the human being."
