I listened to an intriguing episode of Radiolab on my way home from SPX, concerning thought and language and the connections between the two. The sciencemasters that were interviewed for the first segment of the show posit that they’re pretty much the same thing, and until you have a word for a thing it’s nearly impossible to conceptualize it. That said, I know a lot of people who can talk plenty and thought never enters into it, so I guess the relationship between the two isn’t so cut and dry.
