Reality as an Exclusive Attribute of Definite Predicates: A Semantic Approach with Quantum Analogies

This paper presents an original conception according to which reality is not an attribute of objects or subjects, but of definite predicates. We distinguish clearly between reality (applicable to definite predicates) and truth (applicable to propositions). A definite predicate is real if and only if there exists a unique subject satisfying its description and the sufficient conditions for its instantiation obtain. Analogies with quantum mechanics illustrate the objective indeterminacy of definite predicates and the conditional evolution of their reality. We introduce a novel perspective: reality about the past is not fixed; it evolves, and must evolve, by present predication, even though the past itself does not change. This principle applies to all past subjects and their definite descriptions. Applications include historical, geographical, and physical descriptions, demonstrating a coherent semantic framework.
