The christian fundamentalist school book series A Beka Book is
advertised, among other things, with the following:
“A Beka Book provides attractive, legible, workable traditional
mathematics texts that are not burdened with modern theories such as
set theory.”
… wait a moment. Set theory and “burdened?” “Modern?” 1874 is not
exactly what I’d call “modern,” but then I’m a computer scientist so
my views on “modern” and “old” are somewhat skewed. But “burdened?”
Set theory is one of the most fundamental theories of mathematics and
important pre-requisite for most higher-level stuff. So. Uh. What?
