|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.|

Predicates are the sentence frame, its content is determined by the set of asymmetric SMSICs
Definition predicate/Brandom: here: equivalence class of substitutionally equivalent sentences.
Predicate/Brandom: no equivalence class - it therefore selects no objects - SMSIC for predicates asymmetrical - structural similarities.
Predicates/Brandom: cannot be eliminated, expressively essential - e.g. "whatever is, is moving".
Predicate/Brandom: essential asymmetry - problem: the difference between e.g. "Brutus killed Caesar" and "Caesar killed Brutus" cannot yet be ascertained - therefore, one must understand the predicates (T > S) but not their role as functions or as frames.
