Consciousness, a unique and perplexing mental state, has been the subject of debate for philosophers and scientists for millennia. And while it is widely agreed within contemporary philosophy that consciousness is a problem whose solutions are likely to determine the fate of any number of other problems, there is no settled position on the ultimate nature of consciousness. This series of 12 penetrating and thought-provoking lectures by an acclaimed teacher and scholar approaches its subject directly and unflinchingly. Rather than trying to explain away consciousness, or hide behind convenient slogans like "it's all in your brain," Professor Robinson reviews some of the problems that philosophers, psychologists, scientists, and doctors face when taking on this vexing topic, addressing questions that include. What is the most promising way to study this subject? What are the implications that arise from the fact that we have consciousness? What are the ethical and moral issues raised by its presence - or absence? Professor Robinson draws on the wisdom of the world's greatest thinkers to shed light on the ethical debates involved in any examination of consciousness, including John Locke, Ludwig Wittgenstein, and Aristotle. And he also explores the impact of modern physics and medicine on our understanding of the self. Pondering questions from the most fundamental to contemporary quandaries about artificial intelligence, you'll gain new insights into the complexity of how great minds define consciousness.
