Ponderings of science, philosophy, history, society, and many other topics
In the last post, in response to my criticism of Chalmers for relying on the standard but vague "something it is like" definition of phenomenal consciousness, someone pointed out that Chalmers has talked before metaphorically about a movie playing in our head, notably at the beginning of his TED talk on consciousness. I think this … Continue reading The problem with the theater of the mind metaphor
This talk by David Chalmers on the relationship between consciousness and moral status is pretty interesting. You don't have to watch the video to follow this post, but it's in response to arguments he makes in the talk. The video is 75 minutes but the talk only lasts about 50 minutes with a Q&A afterward. … Continue reading Consciousness and moral status
A crucial point about science I couldn't have put any better. Science is an ongoing conversation, not a series of absolute determinations. Anytime a radical result is announced, we should really think about its implications in terms of if the results are replicated or hold up under further analysis. Every paper is only part of … Continue reading No Gospel Truth in Science
Philip Ball has an article up at Aeon: Life with purpose, which resonates in theme with the one a few weeks ago by Michael Levin and Dan Dennett on purpose in nature. Like Levin and Dennett, Ball argues that we shouldn't be shy about discussing purpose in biology, or feel obliged to put quotes around … Continue reading Agency, consciousness, and purpose
The black hole information paradox has been receiving some attention lately. This is the fact that information, that is any pattern of matter, that falls into a black hole is completely crushed as it approaches the singularity, losing whatever differentiation it might have had before. This has long been recognized as a problem, because in … Continue reading A basic question on the black hole information paradox
Well, that's a relief. Even though there were warnings for weeks and months before the election about a "red mirage" that might happen election night, a result of Trump supporters voting on election day and Biden supporters voting heavily by mail, and the order in which the ballots would be counted, even though many of … Continue reading An election fit for 2020
Somewhat related to the previous post, I just saw this video from Matt O'Dowd discussing why the block universe is such a compelling concept. https://www.youtube.com/watch?v=EagNUvNfsUI&t=12s The second video in the series discusses the effect quantum mechanics might have on this concept. It reminds me why cosmologists seem to be more comfortable with the Many Worlds … Continue reading A PBS Space Time series on time and the block universe
Click through for source and bonus red button caption at smbc-comics.com. This SMBC gets at something that's often bothered me about the way many people talk about the block universe concept. The block universe is the idea that if the universe is fully deterministic, then its entire history from beginning to end exists in an … Continue reading The block universe is interesting, but not comforting
I'm always interested in new takes on the demarcation between science and non-science, so after seeing the New Yorker write up on Michael Strevens' new book, The Knowledge Machine: How Irrationality Created Modern Science, it seemed like something I needed to read. Strevens begins by examining the two leading theories of science: Karl Popper's falsifiability … Continue reading The iron rule of science?
I voted. I did early voting, although I would have preferred to have voted by mail. However, my state's Republican dominated legislature did everything they could to prevent that. The state only offered mail-in voting after they lost a lawsuit, and then only for relatively narrow cases. To do it, I would have had to … Continue reading Voting in the general election, 2020 edition
