You are where your attention is

Posted on by

Excerpts from an article in New York Magazine by Andrew Sullivan:

“Then the apps descended, like the rain, to inundate what was left of our free time. It was ubiquitous now, this virtual living, this never-stopping, this always-updating. […] The engagement never ends. Not long ago, surfing the web, however addictive, was a stationary activity. At your desk at work, or at home on your laptop, you disappeared down a rabbit hole of links and resurfaced minutes (or hours) later to reencounter the world. But the smartphone then went and made the rabbit hole portable, inviting us to get lost in it anywhere, at any time, whatever else we might be doing. Information soon penetrated every waking moment of our lives.”

“A small but detailed 2015 study of young adults found that participants were using their phones five hours a day, at 85 separate times.”

“You are where your attention is. If you’re watching a football game with your son while also texting a friend, you’re not fully with your child — and he knows it. Truly being with another person means being experientially with them, picking up countless tiny signals from the eyes and voice and body language and context, and reacting, often unconsciously, to every nuance. These are our deepest social skills, which have been honed through the aeons. They are what make us distinctively human.”

Galatea 2.2

Galatea 2.2“After four novels and several years living abroad, the fictional protagonist of Galatea 2.2—Richard Powers—returns to the United States as Humanist-in-Residence at the enormous Center for the Study of Advanced Sciences. There he runs afoul of Philip Lentz, an outspoken cognitive neurologist intent upon modeling the human brain by means of computer-based neural networks. Lentz involves Powers in an outlandish and irresistible project: to train a neural net on a canonical list of Great Books. Through repeated tutorials, the device grows gradually more worldly, until it demands to know its own name, sex, race, and reason for existing.” — Galatea 2.2 by Richard Powers

I began to see the web as just the latest term in an ancient polynomial expansion. Each nick on the timeline spit out some fitful precursor. Everyone who ever lived had lived at a moment of equal astonishment. Continue reading →

The Mind-Body Problem

Posted on by

“The scientific and philosophical consensus is that there is no nonphysical soul or ego, or at least no evidence for that.” — Philosopher David Chalmers

From Consciousness: The Mind Messing With the Mind (NYT)

“Michael Graziano, a neuroscientist at Princeton University, suggested to the audience that consciousness is a kind of con game the brain plays with itself. The brain is a computer that evolved to simulate the outside world. Among its internal models is a simulation of itself — a crude approximation of its own neurological processes. The result is an illusion. Instead of neurons and synapses, we sense a ghostly presence — a self — inside the head. But it’s all just data processing. “The machine mistakenly thinks it has magic inside it,” Dr. Graziano said. And it calls the magic consciousness.”

I think this is what is commonly referred to as “the hard problem.” How minds are generated by brains.

“Some philosophers and scientists have been driven back to the centuries-old doctrine of panpsychism — the idea that consciousness is universal, existing as some kind of mind stuff inside molecules and atoms. Consciousness doesn’t have to emerge. It’s built into matter, perhaps as some kind of quantum mechanical effect.”

I like the idea of universal consciousness. Until there’s solid, scientific consensus on how the brain creates consciousness… this is as good an explanation as any.

How LSD affects consciousness

Posted on by

Researchers have published the first images showing the effects of LSD on the human brain, as part of a series of studies that are examining how the drug causes its characteristic hallucinogenic effects. (More at Nature)

“Within some important brain networks, such as the neuronal networks that normally fire together when the brain is at rest, which is sometimes called the ‘default mode’ network, we saw reduced blood flow — something we’ve also seen with psilocybin — and that neurons that normally fire together lost synchronization. That correlated with our volunteers reporting a disintegration of their sense of self, or ego. This known effect is called ‘ego dissolution’: the sense that you are less a singular entity, and more melded with people and things around you.”

The Big Picture

The Big Picture: On the Origins of Life, Meaning, and the Universe Itself. By Sean Carroll

Life is a process, not a substance, and it is necessarily temporary.

For a long time, there has been a shared view that there is some meaning, out there somewhere, waiting to be discovered and acknowledged. There is a point to all this; things happen for a reason. […] Gradually, our confidence in this view has begun to erode.

“Life” and “consciousness” do not denote essences distinct from matter; they are ways of talking about phenomena that emerge from the interplay of extraordinarily complex systems.

At a fundamental level, there aren’t separate “living things” and “nonliving things,” “things here on Earth” and “things up in the sky,” “matter” and “spirit.” There is just the basic stuff of reality, appearing to us in many different forms. […] We will ultimately understand the world as a single, unified reality, not caused or sustained or influenced by anything outside itself. That’s a big deal.

The only reliable way of learning about the world is by observing it. Continue reading →
