Super-True Propositions in Supervaluational Semantics

Understanding Super-True Propositions

Super-true propositions are a key concept in supervaluational semantics, a framework designed to handle vagueness and indeterminacy in language. Unlike classical logic, which often relies on sharp distinctions, supervaluationalism acknowledges that many terms are inherently vague.

The Role of Precisifications

In supervaluational semantics, the truth of a statement is determined by considering all possible ways to make the vague terms in the statement precise. These precise interpretations are called precisifications.

Defining Super-Truth

A proposition is considered super-true if it holds true across all possible precisifications. This means that no matter how you interpret the vague terms (e.g., ‘tall’, ‘bald’, ‘heap’), the proposition’s truth value remains constant.

Contrast with Classical Truth

This contrasts with classical truth, where a proposition is either true or false based on a single, fixed interpretation. Super-truth provides a way to assign a truth value even when a unique, precise interpretation is unavailable.

Applications and Implications

The concept of super-truth has implications for understanding vagueness, truth conditions, and the semantics of natural language. It offers a way to make sense of statements that might otherwise be considered unanswerable due to their ambiguity.

Challenges and Considerations

One challenge is the potential for a large or infinite number of precisifications, making practical evaluation difficult. Additionally, the philosophical underpinnings of choosing which precisifications are relevant can be complex.
