Consciousness likely not unique to earthlings, paper says

Does consciousness depend on flesh and blood? The answer is almost certainly no, according to Eric Schwitzgebel, a distinguished professor of philosophy at the University of California, Riverside. In a new working paper, Schwitzgebel and Jeremy Pober, a former UCR graduate student who is now a postdoctoral researcher at the University of Lisbon, assert that consciousness is likely possible in life forms made of very different stuff. Think of the five-limbed alien with a rocklike exterior in the recent blockbuster movie "Project Hail Mary."
