Is there a theory that explains the essence of consciousness? Or is consciousness itself just an illusion? The 'last great mystery of science', consciousness is now a significant area of research, expanding rapidly for students of psychology, philosophy, and neuroscience.

This groundbreaking book brings together all the major theories of consciousness studies—from those rooted in traditional Western philosophy to those emerging from neuroscience, quantum theory, and Eastern philosophy. It examines topics such as how subjective experiences arise from objective brain processes, the basic neuroscience of consciousness, altered states of consciousness, mystical experiences, dreams, and the effects of drugs and meditation.

The book also discusses the nature of self, the possibility of artificial consciousness in robots, and the question of whether or not animals are conscious. Enhanced by numerous illustrations and profiles of important researchers, the book includes self-assessment questions, further reading suggestions, and practical exercises that help bring the subject to life.

For all those intrigued by what it means to be, to exist, this book could radically transform your understanding of your own consciousness.
