Neuroscientist and writer Anil Seth discusses the idea of consciousness, its historical interpretation, and modern development as a theory of existence.

If scientists could create an alternative mechanism to your biological brain that would reproduce all of its measurable functions but wouldn't be vulnerable to disease and old age, would you sign up?

Why does the idea of consciousness as an intangible quality of the human brain that can't be recreated by modern science remain such a powerful one?

Anil Seth is a professor of Cognitive and Computational Neuroscience at the University of Sussex who has published numerous works on the philosophy and science of consciousness.

In this book, Seth discusses consciousness from numerous angles, reminding us that we have a long way to go before we can feel confident we know exactly what it is.
