From the best-selling author of How to Change Your Mind, a pioneering search for consciousness in the brain and beyond.

A World Appears is the story of the quest to solve the greatest mystery in nature: consciousness. How does it feel to be you with your own personal feelings, thoughts and experiences? Every one of us is intimately familiar with consciousness, but no one knows how – or why – it came to be that three pounds of grey matter can generate a subjective point of view.

The early 1990s marked the birth of a new science of consciousness, based on the assumption that the phenomenon could be explained in terms of brain activity, but that effort is faltering, and wilder ideas, such as panpsychism, are now getting a hearing. Indeed, there is now reason to doubt that ‘objective science’ as we have known it since Galileo has the right tools to plumb first-person experience. A World Appears takes Michael Pollan from the laboratories where scientists are searching for the neural correlates of consciousness to encounters with philosophers and novelists and Buddhist monks, whom he finds have just as much to teach us about consciousness, if not more.

A story that begins in a brain lab in Seattle ends, of all places, in a cave in the mountains of New Mexico, where the author discovers that explaining consciousness may be less urgent than learning to practice it in our everyday lives.

'A World Appears is a big, generous, illuminating and beautifully written inquiry into the essence of our being-in-the-world, of being, simply, alive' the Financial Times

'Lucid and impassioned...a fabulous and mind-expanding exploration of counciousness...' the Guardian

'Razor-sharp, reassuringly sceptical, sensitive and grounded...you could not hope for a more judicious or readable summary of the scientific state of affairs' the Sunday Times
