What that consciousness might look like

is another matter entirely.

Could aliens exhibit empathy,

self-awareness, love, hate, or fear...?

The spectrum of alien appearances across 'popular culture' is vast, limited only by human imagination.

From the sharp, angular features of Captain Spock to the dinosaur-like neck and big, expressive eyes on E.T. the Extra-Terrestrial, these beings embody logic, deep wisdom, and emotional connection.

This is no coincidence.

Humanity's deepest wish is that if (when) we encounter another intelligent life form, it will be conscious, capable of understanding, and maybe even befriend us.

But could such beings really exist...?

"Certainly," says Christof Koch, Ph.D., a neuroscientist and prominent figure in the field of consciousness studies.

 

"Any complex system, whether evolved on Earth or elsewhere, could be conscious."

What that consciousness might look like is another matter entirely.

Could aliens exhibit empathy, self-awareness, love, hate, or fear?

To answer these questions, consider panpsychism, an ancient cosmic theory that suggests consciousness could be a ubiquitous feature of the universe, akin to gravity or charge.

This idea, dating back to ancient Greek philosophers like Thales and Plato, has seen a resurgence in the 21^st century as mainstream scientific approaches struggle to fully explain consciousness.

"Instead of starting with physical processes and trying to get consciousness out of that, we start with consciousness and try to get physics out of it",

...says Koch, who's currently serving as a meritorious investigator at the Allen Institute, a bioscience nonprofit based in Seattle, Washington.

That means panpsychism might help us solve the "hard problem of consciousness":

how the brain, a gooey mass of neurons, produces subjective experiences and an inner world of colors, sounds, tastes, and fantasies.

But first, we need to rethink our assumptions about the world that have been in place for the past 400 years, before the scientific revolution, when theories like panpsychism were more mainstream.

The perfect exercise?

Considering alien consciousness...!

Theoretical physicist and cosmologist Paul Davies, Ph.D., suggests that alien consciousness could be radically different from human consciousness, operating on principles fundamentally foreign to us, making communication a significant challenge.

Or, extraterrestrials might rely on artificial intelligence (AI) rather than organic brains, says Susan Schneider, Ph.D., a philosopher and cognitive scientist.

"Maybe they have gaseous forms," offers Philip Goff, Ph.D., a professor of philosophy at Durham University, who says we can only speculate about how aliens and their consciousness may manifest.

Despite these challenges, mathematics could be our common language, he says. There's also the speculative possibility of something like telepathy - which panpsychism doesn't rule out.

Consciousness, Goff argues, goes beyond what physical sciences can explain.

"It is in the realm of metaphysics," he says.

Interestingly enough, other experts agree.

Psi phenomena - paranormal events such as telepathy, precognition, or psychokinesis that point to the existence of abilities beyond the scope of current scientific understanding - could play a key role in understanding alien consciousness, says Dean Radin, Ph.D., chief scientist at the Institute of Noetic Sciences.

"Adequate models of psi phenomena will probably require philosophies that look a lot like panpsychism," he explains.

Still, some experts are outright skeptical of panpsychism.

Seth Shostak, Ph.D., a senior astronomer at the SETI Institute, argues consciousness evolved simply because it aids survival.

"That's all nature really cares about," he says.

Shostak also believes intelligence - particularly the kind that leads to communication - needs a structured system to thrive in.

"Intelligence requires some sort of machinery, like a brain, which needs to be organized," he says.

Given the universe's vastness and age, intelligent life capable of communication, or what we perceive as conscious life, might be "rare" (sic)...

"You'll only hear from those who can 'build' a radio transmitter...", Shostak says.

Those are the "truly intelligent" ones.

As for the other potential intelligences out there... maybe we just don't have the means to listen in - yet...
