Depending on your own field of interests, you might dig this Scientific American article on whether language determines perception, noting that in most languages that have only three color terms (!) they are almost always the same (warm, cool, and white). Also given are some intriguing examples of directional perception across cultures.

I discovered this article through Lambda the Ultimate, a site devoted to programming languages, and it's curious to see issues like linguistic relativism crop up there. It's plausible that people interested in programming languages have a high overlap with people interested in natural language, even though the two are quite different and the aims of research in the two areas have nothing in common.

There seems to be a fascination with those discrete, recombinable units per se, and a tendency to want to know what they can accomplish in all their many lives.
