Relations To Other Models
The well-founded semantics can be viewed as a three-valued version of the stable model semantics. Instead of only assigning propositions true or false, it also allows for a value representing ignorance.
For example, if we know that
Specimen A is a moth if specimen A does not fly during daylight.
but we do not know whether or not specimen A flies during the day, the well-founded semantics would assign the proposition ``specimen A is a moth`` the value bottom which is neither true nor false.

—Ralph Waldo Emerson (1803–1882)
“When any one of our relations was found to be a person of a very bad character, a troublesome guest, or one we desired to get rid of, upon his leaving my house I ever took care to lend him a riding-coat, or a pair of boots, or sometimes a horse of small value, and I always had the satisfaction of finding he never came back to return them.”
—Oliver Goldsmith (1728–1774)
“Today it is not the classroom nor the classics which are the repositories of models of eloquence, but the ad agencies.”
