" Lots of people believe consciousness is a fundamental property of the universe, like space and time. If that's the case, then it is turtles all the way down. We'll have this debate about our microbiome. About rocks and atoms and quarks. Until we have Gaia consciousness, there will always be an us-them divide, always a next frontier for empathy. "
