| Existence predicate, philosophy, logic: as opposed to properties that are attributed by predicates existence is no such property. It is therefore only possible in certain systems and under certain conditions to form an existence predicate. E.g. (∃x)(Fx) - "There is at least one object with the property F" here the "∃" is no existence predicate, but an existential quantifier. See also existence, predicates, predication, properties, quantification, existence statements, existential quantification, semantic ascent, substitutional quantification._____________Annotation: The above characterizations of concepts are neither definitions nor exhausting presentations of problems related to them.
