|Predicates, philosophy, logic: predicates are symbols that can stand in logical formulas for properties. In fact, not every predicate stands for a property, since it has contradictory predicates, but no contradictory properties. For example, one can think of a predicate "squaround" for "square and round", that is, two properties that exclude each other. One can then truthfully say "Nothing is squaround". There are therefore more predicates than properties. See also round square, scheme characters, quantification, 2nd level logic, predication, attributes, adjectives.|

Predicate / property / Armstrong / (s): predicate unequal property - a predicate "to be a mass" is permitted, but no real property! - Armstrong: something specific falls under "determinable" (> determinates,> determinables) - Problem: properties of properties: regress possible. - Then pontics: as between e.g. redness and a certain hue - ArmstrongVs: not multiply like those for which they are only a shadow of predicates or be constituted by classes of particulars.
