As I've written about before on these pages, of all the 'Big Questions' in science, the issue of those slippery, tricksy quantities we call consciousness, awareness, and intelligence is one of the most challenging. That's especially true when it comes to any sense of the universality of such things. We're barely beginning to recognize the extraordinarily sophisticated, yet alien, functioning of terrestrial neighbors like cephalopods, let alone any hypothetical life elsewhere.
Furthermore, our current quest to find new worlds that might produce and sustain living systems is still in its infancy. There are a host of relatively mundane, but highly technical hurdles to overcome: from the decoding of stellar light and planetary compositions to the measurements of biomarkers, seasonal cycles, and the disentangling of complicated chemistry and contingency.
So it can seem a bit premature to be talking about the origins and nature of awareness, of minds in any cosmic sense. Except, there appear to be deep-rooted commonalities between the emergence of complex chemistry and life, and the emergence of other phenomena - such as organism awareness, agency, and perhaps consciousness. Could it be that answers to all these puzzles converge on deeper principles?
