Ponderings of science, philosophy, history, society, and many other topics
Last week, Science Magazine published an interesting study on bird consciousness: A neural correlate of sensory consciousness in a corvid bird. The study conducted an experiment where crows were trained to respond to a sensory stimulus. The stimulus itself could be at the threshold of perceptibility, above that threshold, or missing. After the stimulus (or … Continue reading The consciousness of crows
Note: I answer the questions asked here in a later post. I've written about the bizarre nature of quantum physics many times, providing a lightning primer back in May on three major interpretations: Copenhagen, pilot-wave, and many worlds. The many worlds interpretation (MWI) is often summarily dismissed by people, often along with visceral shudders or … Continue reading David Deutsch’s version of many worlds
Last night I finished reading Ada Hoffmann's The Outside, a pretty strange but interesting space opera. In the far future, humanity is ruled by AI gods. Humans invented the gods, although there are hints it was more complicated than that, like maybe there was a singularity event or process of some kind. The gods now … Continue reading The Outside
(Warning: neuroscience weeds) Earlier this year I discussed Victor Lamme's theory of consciousness, that phenomenal experience is recurrent neural processing, that is, neural signalling that happens in loops, from lower layers to higher layers and back, or more broadly from region to region and back. In his papers, Lamme notes that recurrent processing is an … Continue reading The unproductive search for simple solutions to consciousness
I just finished watching the first three episodes of the new HBO Max series: Raised by Wolves. Lamentably, HBO made this difficult since they've been in a dispute with Roku, my preferred steaming platform, on getting an app into their environment. I had to watch it on as ASUS Chromebook mini I keep connected to … Continue reading Raised by Wolves
For some reason, Mary's room has been garnering attention lately. This TED Ed video on it was shared on Aeon's site this week. https://www.youtube.com/watch?v=mGYmiQkah4o The wording of the actual thought experiment is important, so quoting Frank Jackson's words (via the Wikipedia article on the knowledge argument): Mary is a brilliant scientist who is, for whatever reason, … Continue reading The problem with Mary’s room
Jonathan Birch has an interesting paper in Noûs: The search for invertebrate consciousness. Birch notes that there is no consensus on whether any invertebrates are conscious, and no agreement on a methodology for establishing whether they are. He starts off assessing the difficulties of applying many human centric theories, such as global workspace, which don't … Continue reading The facilitation hypothesis
