[racket] Little Schemer, lat?

Fun topic!

In pure mathematics there is the evocative expression vacuuous truth
<http://en.wikipedia.org/wiki/Vacuous_truth> to describe statements about
the empty set, e.g. "I have eaten all the vegetables on my plate" when
there were no vegetables there to begin with.

Personally, I find an attitude of treating such discussions as formal games
rather than quests for absolute truth to be fruitful when considering these
issues.
