"forall" is a textual way of writing the universal quantifier, which is otherwise written as an upside-down capital A It corresponds fairly closely to the English words "each" and "every" Thus, forall(X, likes(X, icecream)) would be read as "for every entity X, X likes icecream" or just "everything likes icecream" This would be too broad a statement, as it would allege that, for example, rocks like icecream It is usual therefore to restrict the proposition to something like: forall(X, is_person(X) => likes(X, icecream)) i e "Every person likes icecream " That is, we are restricting the type of X to persons In some cases, it is more reasonable to abbreviate the type restriction as follows: forall(X : person, likes(X, icecream)) See also exists
