In particular, I like this: "C++ is dumb, and you can't write smart systems in a dumb language. Languages shape the world. Dumb languages make for dumb worlds." (If this sounds superficial, read the article -- he backs it up well.) It seems so true though -- language shapes (or at least, expresses) the way we think and therefore has an impact on everything we think about, and when you create something, the first thing you need is a language to describe it in.
Some of Stevey's other articles are good too, see http://www.cabochon.com/~stevey/blog-rants/
