Those of you who've known me a while may remember that I dislike accepting philosophical labels. For example, although the labels "materialist" or "physicalist" are more or less accurate descriptions of what I think, they often seem to imply an ideological rigidity I'm not comfortable with. My attitude toward these labels somewhat resonates with Neil … Continue reading Scientific theories and prescriptive vs descriptive instrumentalism

The rules of time travel?
In a somewhat whimsical podcast episode, Sean Carroll explores the physics and "rules" of time travel. Probably the first two thirds explore the physics. Carroll notes that if time travel under general relativity is at all possible, it would more likely involve a spaceship attempting to navigate some kind of closed timelike curve than stepping … Continue reading The rules of time travel?
Talking across the boundary of the epiphany
When learning a new idea or concept, often it doesn't make a lot of sense at first. The various descriptions may seem dubious, and we might fail to see the structural similarities that bind them. Then, at some point, if we keep at it and are lucky, we "get it", it "clicks", we have an … Continue reading Talking across the boundary of the epiphany
The iron rule of science?
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?
Fostering an open mind
There's an interesting article in Psyche: How to foster ‘shoshin’. "Shoshin" is a Japanese Zen word referring to a "beginner's mind." The idea is that when we take ourselves to be a beginner in a subject, or at least still a student of it, we're more open to possibilities. But as we begin to think … Continue reading Fostering an open mind
The mechanical philosophy and mysterianism
Noam Chomsky published an essay on his web site a few years ago: Science, Mind, and Limits of Understanding. Chomsky's thesis is that there are areas of reality that science is simply incapable of understanding. He uses as his principle example, the case of Isaac Newton's understanding of gravity. Chomsky acknowledges that this is a … Continue reading The mechanical philosophy and mysterianism
Scientific and philosophical possibilities for immortality
A question that has come up in a couple of recent conversations: Is there any hope within a scientific or philosophical view of reality for immortality, something like an afterlife that is typically promised in the major religions? The most popular hope these days is the Technological Singularity, the idea that sometime soon we will … Continue reading Scientific and philosophical possibilities for immortality
The problem with philosophical thought experiments
James Wilson has an article up at Aeon, looking at the trolley problem and other ethical and philosophical thought experiments. One of the things he discusses is the notion that many philosophers have, along with many fans of particular thought experiments, that they're sort of like a scientific experiment. It's not that unusual for someone … Continue reading The problem with philosophical thought experiments
Pain is information, but what is information?
From an evolutionary standpoint, why does pain exist? The first naive answer most people reach for is that pain exists to make us take action to prevent damage. If we touch a hot stove, pain makes us pull our hand back. But that's not right. When we touch a hot surface, nociceptors in our hand … Continue reading Pain is information, but what is information?
Is the ultimate nature of reality mental?
Philosopher Wilfrid Sellars had a term for the world as it appears, the "manifest image." This is the world as we perceive it. In it, an apple is an apple, something red or green with a certain shape, a range of sizes, a thing that we can eat, or throw. The manifest image can be … Continue reading Is the ultimate nature of reality mental?
