Ponderings of science, philosophy, history, society, and many other topics
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
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
What is the difference between magic and science? It's been a while since I shared an Existential Comic. This one gets at a question we've discussed before, although it's been several years. What exactly is the distinction between the physical and non-physical, in this case between science and magic? Credit: https://existentialcomics.com/comic/537 Corey Mohler, the author, has a … Continue reading Existential Comics: the philosophy of magic
I think the reasons someone reaches a conclusion are at least as important as the conclusion itself. Recently someone I know changed their mind about a topic. Where they had previously disagreed with me on something, they now agree. Which was great, except, I found their reasons for the change problematic. It reminded me that I often have … Continue reading Reasons and conclusions
It seems like theories that are causally complete are better than ones with gaps. In thinking about this, I'm reminded of a Psyche article I shared a few years ago on fostering an open mind. One of their pieces of advice resonates with an outlook I've had for some time. If embarking on a full-on explanation … Continue reading Causal completeness
The Everett theory of quantum mechanics is testable in ways most people don't realize. Before getting into how or why, I think it's important to deal with a long standing issue. Everettian theory is more commonly known as the "many worlds interpretation", a name I use myself all the time. But what's often lost in the discussion … Continue reading Testing Everettian quantum mechanics
Are quantum states and the overall wave function real? Or merely a useful prediction tool? The mystery of quantum mechanics is that quantum objects, like electrons and photons, seem to move like waves, until they're measured, then appear as localized particles. This is known as the measurement problem. The wave function is a mathematical tool for modeling, … Continue reading Those inconvenient quantum interference patterns
Scientific breakthroughs often begin with someone saying, "Don't panic. This crazy sounding assumption is just to make the math work." Nicholaus Copernicus, when he developed his theory of heliocentrism (the earth orbits the sun), was operating from a scientific realist view. In other words, he thought his system reflected actual reality, or at least reflected it … Continue reading Is it just the math?
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?
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
