Consciousness must be adaptive

A cuttlefish

The New York Declaration on Animal Consciousness has been making a lot of headlines. The declaration itself has somewhat careful language in terms of what it's asserting, but many of the headlines don't. The declaration is short, so it's easy to quote in full. Which animals have the capacity for conscious experience? While much uncertainty … Continue reading Consciousness must be adaptive

Some thoughts on Daniel Dennett’s ideas

Philosopher Daniel Dennett

Yesterday Daniel Dennett died. He was 82, about the same age as my father when he died a few years ago. I think I've mentioned before that the first writer I read on consciousness was Susan Blackmore. But I know Dennett wasn't far behind, likely based on Blackmore's positive discussions of his work, but also … Continue reading Some thoughts on Daniel Dennett’s ideas

Is AI consciousness an urgent issue?

Poster for The Creator, showing a soldier with a robot child

AI consciousness seems like an easier thing to ponder when you approach it from a functionalist viewpoint. Sunday I watched the movie The Creator. The premise is a few decades in the future, we've managed to create sentient robots. At first, all seems well, with them being a boon for humanity. Then a nuclear bomb goes off in … Continue reading Is AI consciousness an urgent issue?

The unity of storage and processing in nervous systems

I think the brain is a computational system and what we generally refer to as the mind and consciousness are some of its computations. But I'm also aware that the brain works very differently from how a typical digital computer works. One criticism of computationalism that I have some sympathy with is the word "computation" … Continue reading The unity of storage and processing in nervous systems

The function of color

Pencils of all the primary colors in a circle

In the history of discussions about consciousness, there have always been ideas that some aspects of human experience are irreducible to physics. Colors have long had a special place in these discussions. During the scientific revolution, colors lost their status as objective properties in the world, with people like Galileo relegating them to secondary qualities … Continue reading The function of color

Do regular people see a hard problem of consciousness?

This week the latest Mind Chat episode focused on whether regular people actually perceive a hard problem of consciousness, or if it's an issue largely created by philosophers. Keith Frankish and Philip Goff interview Michelle Liu and Edouard Machery. (The video is a bit over two hours. You don't necessarily need to watch it to … Continue reading Do regular people see a hard problem of consciousness?

The debate between phenomenal realism and illusionism, and the scope of perceptual properties

In the last post, I pondered the idea that the real difference between a realist and anti-realist stance toward a scientific theory is about how broad or narrow the scope of the theory might be, about it's domain of applicability. An anti-realist takes a narrower view on scope; such as that the theory can be … Continue reading The debate between phenomenal realism and illusionism, and the scope of perceptual properties

Russellian monism, the same as illusionism?

I usually have to wait for the audio version of these Mind Chat podcasts, but this one seemed a reasonable length and I had some time this weekend. Keith Frankish, an illusionist, and Philip Goff, a panpsychist, interviewed Noam Chomsky for his views on consciousness. (The video is about 72 minutes. You don't necessarily need … Continue reading Russellian monism, the same as illusionism?

Consciousness, illusions, and definitions

Strawberries

I've discussed many times that the word "consciousness" has a variety of meanings. But most commonly, the various meanings can be grouped into two broad categories. One refers to some combination of functionality, typically the information processing that happens in the brain enabling an organism to take in, assess, and use information about itself and … Continue reading Consciousness, illusions, and definitions
