19317 | An open sentence is satisfied if the object possess that property [Kirkham] |
Full Idea: An object satisfies an open sentence if and only if it possesses the property expressed by the predicate of the open sentence. | |
From: Richard L. Kirkham (Theories of Truth: a Critical Introduction [1992], 5.4) | |
A reaction: This applies to atomic sentence, of the form Fx or Fa (that is, some variable is F, or some object is F). So strictly, only the world can decide whether some open sentence is satisfied. And it all depends on things called 'properties'. |
