Hi, reader. I wrote this in 2002 and it's now more than five years old. So it may be very out of date; the world, and I, have changed a lot since I wrote it! I'm keeping this up for historical archive purposes, but the me of today may 100% disagree with what I said then. I rarely edit posts after publishing them, but if I do, I usually leave a note in italics to mark the edit and the reason. If this post is particularly offensive or breaches someone's privacy, please contact me.

Jade thinks I'm copping out when I make a predicate true or false by assigning the null set or the universe of discourse to the predicate's extension. I say it's perfectly fine, contrasting my "Wal*Mart Way" to her "Williams-Sonoma Method."
