Via Language Log, comes this urging from Helen Zille (the leader of the South African Democratic Alliance party):

While back-tracking entries in my server log, I ran across the quote that is the title of this post. It comes from Steph Swainston's The Year of Our War. Amazon has "search inside" for this book, so I was able to pull up the context. It's a fantasy, and refers to several invented languages:

When I taught linguistics-for-teachers courses, I spent a significant portion of my class time trying to get students to question their assumptions about language, assumptions that, whether they learned them in school or by general osmosis, are based on premises that linguists know to be incorrect. It always distressed me, therefore, when certain students would make it to the end of the course and drop some comment that made it clear they had internalized little of what I was trying to communicate.

I am something of a creature of habit, and therefore will stick to the same blogs for a long time. Lately though, I've been trying to expand my reading, and so I've been following links from the sites I frequent to language-oriented sites that I haven't visited before. In the process, I have discovered 1) Language Log really needs to update their links. At least half the sites on their sidebar are defunct.
