They all have negation as failure, the key elementThe not operator of Prolog is not a part of Horn clause system. It is
required to reject self-contradictory expressions.
not the same as the not operator of ordinary logic. Therefore one nust
be careful with its use and interpretation.
You have not defined what you mean with "reject" and how that relates
to the behaviour of Prolog programs.
The failure to prove X from Facts and Rules
means that X is untrue yet not necessarily false.
The failure to prove X or ~X from Facts and Rules
means that X is untrue and unfalse, thus not a
truth bearer.
cannot be determined either way with Prolog rules.
then we can know by Prolog Facts that cats are animals.
that "cats are animals" was anything but pure gibberish
until this was specified.
Sorry, you are just proving your stupidity.
The words had there meaning long before "logic" was invented.
