Having taught the square of opposition many times, I think the main use of this article for most users will be: what is the square, exactly, and what do the different relationships between points on the square mean? So we should add a nice graphic. There must be a zillion free nice ones out there already. I myself might have one if you can't find one, but I'm sure it wouldn't be the best. Very cool that you could find the square from a Latin text, but this is mainly of historical interest and does not illuminate the square at all for modern students and logicians. In general, this is a historical introduction. That's interesting as far as it goes, but more a lucid introduction with plenty of examples, similar to what is found in a well-written logic text, would be more helpful. Then a historical section could be added to explain the history of the square.

By the way, the article needs to be linked throughout.

Also, I notice this comes from Wikipedia. Please always check the "Content is from Wikipedia?" unless you are the sole author of the article. --Larry Sanger 07:48, 16 February 2008 (CST)
