Well, I find this a bit disappointing. I was hoping that the contest between global workspace theory (GWT) and integrated information theory (IIT) would be announced sometime this year. Apparently, I'm going to have to wait awhile: Pitts describes the intention of this competition as “to kill one or both theories,” but adds that while … Continue reading The battle between integration and workspace will take a while

The video embed on the previous post, which had gone dead, is now updated. Hopefully this one will endure.
Daniel Dennett on consciousness and the hard question
This interview is pretty much classic Daniel Dennett. He starts off pointing out that introspection is unreliable, that our beliefs about our inner experience are what need to be explained, not necessarily what the beliefs purport to be reality. He doesn't name the meta-problem, but it's clear that, and related concepts, are what he's talking … Continue reading Daniel Dennett on consciousness and the hard question
A response to the unfolding argument: a defense of Integrated Information Theory
Back in May, I shared a paper that made a blistering attack on the integrated information theory (IIT) of consciousness. A major point of IIT is that a specific causal structure is necessary to generate phenomenal experience, namely a feedback or recurrent neural network, that is, a neural network with structural loops. To be clear, … Continue reading A response to the unfolding argument: a defense of Integrated Information Theory
The issues with higher order theories of consciousness
After the global workspace theory (GWT) post, someone asked me if I'm now down on higher order theories (HOT). It's fair to say I'm less enthusiastic about them than I used to be. They still might describe important components of consciousness, but the stronger assertion that they provide the primary explanation now seems dubious. A … Continue reading The issues with higher order theories of consciousness
The Witcher
I just finished watching The Witcher on Netflix. This was a series that I initially resisted getting into. From a distance, it looked too much like a Game of Thrones knockoff. But after numerous people recommended it, I decided to give it a try. It turns out that The Witcher is based on a book … Continue reading The Witcher
Global workspace theory: consciousness as brain wide information sharing
Lately I've been reading up on global workspace theory (GWT). In a survey published last year, among general consciousness enthusiasts, integrated information theory (IIT) was the most popular theory, followed closely by GWT. However, among active consciousness researchers, GWT was seen as the most promising by far (although no theory garnered a majority). Since seeing … Continue reading Global workspace theory: consciousness as brain wide information sharing
The role of beauty and simplicity in scientific theories
In the post on Copernicus earlier this week, I noted that his heliocentric theory, right from its initial publication, was hailed as far more mathematically elegant than the Aristotelian / Ptolemaic system, which was taken as the canonical model of the universe at the time. But while everyone hailed Copernican mathematics, virtually no one accepted … Continue reading The role of beauty and simplicity in scientific theories
Lost in Space
When I was very young in the early 70s, I remember coming home after school and watching afternoon TV, a lot of syndicated shows from the 60s. One of those shows was the original Star Trek, in the early years of its syndication run that would pull it out of oblivion and eventually turn it … Continue reading Lost in Space
Merry Christmas
A year ago, I wrote that I hoped there would be more time for blogging in the next year. That time would eventually materialize, but not for several months. Yet, the frequency of posts immediately spiked, and has stayed higher ever since. Did I just end up making more time? Not quite. I realized after … Continue reading Merry Christmas
