Theories of Consciousness examines the multifaceted nature of consciousness, bridging philosophy and psychology to explore what it truly means to be aware. This exploration extends from historical philosophical inquiries into the mind-body problem to modern neuroscience and cognitive science. One intriguing aspect covered is the investigation into whether self-awareness is exclusive to humans or present in other life forms, and how understanding consciousness is vital for advancements in treating neurological disorders. The book dissects prominent theories such as Integrated Information Theory and Global Workspace Theory, emphasizing the necessity of integrating subjective experience with objective data. It progresses by first laying the groundwork with core concepts like qualia, then meticulously examining empirical research including neuroimaging studies and investigations into altered states. Ultimately, it synthesizes these diverse perspectives, proposing a framework for understanding the relationship between subjective experience and objective reality, while also exploring ethical implications for artificial intelligence.
