Philosopher Eric Schwitzgebel and former grad student Jeremy Pober challenge our understanding of consciousness by suggesting that it might not be confined to carbon-based biological substrate in their recent working paper. They propose a new concept called “substrate flexibility,” which could mean that consciousness can exist in different materials, opening up possibilities for life forms beyond Earth.
Schwitzgebel and Pober build upon the ideas of Copernicus, who famously concluded that Earth is not unique in its place in the universe. The duo explores how this idea might impact our understanding of consciousness, asking whether we’re truly alone or if other planets could host conscious beings made of different materials. They argue that the universe must contain diverse, behaviorally sophisticated species that can exist on various substrates.
While the team acknowledges uncertainty and the need for a universal definition of consciousness, they theorize about the possibilities of extraterrestrial life forms and their potential to exhibit consciousness. Their paper proposes that even if Earth is the only planet with life, it’s possible that other planets could support life forms made of unexpected materials. The researchers emphasize that they don’t claim to have found evidence for extraterrestrial life but think it’s worth exploring how the realm of consciousness might extend beyond our planet.
Their ideas spark interesting questions: Can consciousness exist in different materials? What would be required for a species to develop consciousness, and could it happen on other planets? While there’s still much to be discovered, Schwitzgebel and Pober’s work encourages us to consider the vast possibilities of life in the universe.
