Leading philosopher of science Peter Godfrey-Smith dons a wet suit and journeys into the depths of consciousness in his latest book Other Minds. Combining science and philosophy with first-hand accounts of the remarkable intelligence of the octopus, Godfrey-Smith explores how primitive organisms bobbing in the ocean began sending signals to each other and how these early forms of communication gave rise to the advanced nervous systems that permit cephalopods to change colors and human beings to speak. Follow along as Godfrey-Smith shares from his underwater adventures and sheds new light on the octopus brain, the human brain, and the evolution of consciousness.Click here for photos from the program.
