In May 2021 A.C. Grayling ,founder of New College of the Humanities, came to Intelligence Squared to take us on a journey through the history of science, psychology and history itself. In a special lecture drawing from his new book Frontiers of Knowledge he will describe how each field has advanced to where it is now: from the rise of technology to quantum theory; from the dawn of humanity to debates around national histories; from ancient ideas about the brain to modern theories of the mind.

Each advance in these subject areas has further exposed what Grayling calls the paradox of knowledge: that the more we know, the greater becomes the extent of our ignorance.
