|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._____________Annotation: The above characterizations of concepts are neither definitions nor exhausting presentations of problems related to them.

Def simple Predicate/Cresswell: is a predicate, where the condition for the manner in which it has to be represented, is not part of its meaning. - Simple predicates we need for our structured meanings - i.e. those where you can say the meaning is the set of things that satisfy P.
Meaning/Intension/Cresswell: in the case of a simple predicate, the meaning is nothing but the intension.
Def Intension: of the predicate P: what determines the extension in each world._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
