FACT

The kind of clause used in logic programming which has no subgoals and so is always true (always succeeds). E.g.

wet(water). male(denis).

This is in contrast to a rule which only succeeds if all its subgoals do. Rules usually contain logic variables, facts rarely do, except for oddities like "equal(X,X).".
