The Giants Shoulder #39 Consciousness Expert: Alien Minds, Insane Biology and the Evolution of Subjectivity!
Peter Godfrey-Smith is a philosopher of biology, diver, and author of Other Minds and Metazoa — two of the most important works on animal consciousness ever written.
His research explores the octopus not just as an animal, but as an alien intelligence that evolved a complex mind entirely separate from our own.
Octopuses have distributed brains in their arms, no cultural learning, no social lives — and yet they solve problems, play, and even throw objects in rage. They live just 1 to 2 years, mate once, and die — raising a profound question: why would evolution build a mind this sophisticated, only to delete it almost immediately?
Expect to learn why octopus intelligence forces us to rethink consciousness, how their nervous system creates agency without central control, what their bizarre lifespan reveals about the trade-offs of intelligence, why cultural learning might not be necessary for sentience, whether octopuses might dream, and what this means for how subjective experience evolved on Earth. You'll also learn how consciousness may have emerged from sensory integration, how language reshaped the human mind, why inner speech might be the key to unified awareness, whether arms can think, if AI can ever feel — and why octopuses might be the only creatures smart enough to understand what they are, but not live long enough to tell us.
