Scientific theories and prescriptive vs descriptive instrumentalism

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?

Chomsky acknowledges that this is a … Continue reading The mechanical philosophy and mysterianism

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
