If the Logical Positivists’ verifiability theory of meaning were changed to the “verifiability theory of empirical meaning,” a few key issues might arise, both philosophically and in terms of their original goals.
- Expansion of Meaning: The original Verifiability Theory of Meaning proposed by the Logical Positivists held that a statement is meaningful only if it is empirically verifiable, i.e., it can be tested through experience or observation. Changing this to “empirical meaning” could imply a broader or less strict notion of meaning that allows for statements to be meaningful based on some form of empirical grounding, but not necessarily through direct verification. This could conflict with the positivists’ commitment to strict empirical verification, allowing for a wider range of statements that the positivists would have otherwise rejected (like metaphysical or theoretical claims that aren’t directly verifiable).
- Loosening of Empiricist Rigor: The original verifiability criterion was meant to separate meaningful statements from those that are meaningless, especially targeting metaphysical, theological, and other non-empirical assertions. Changing it to “empirical meaning” might loosen the rigorous standards that the Logical Positivists aimed for, allowing for claims that are not strictly verifiable but are still based on empirical methods (e.g., abstract theories or hypothetical constructs that can’t directly be observed). This shift might undermine the positivist’s aim to prioritize only those statements that can be conclusively tested and verified through experience.
- Impact on Theoretical Science: A shift to “empirical meaning” could potentially allow for statements in theoretical science to be considered meaningful even if they are not directly verifiable. This would conflict with the positivist’s initial critique of scientific theories that can’t be empirically tested, which they saw as bordering on meaningless (e.g., the idea of unobservable entities in physics). The change could weaken the distinction between scientific hypotheses and speculative metaphysical claims.
- Ambiguity and Interpretational Challenges: The term “empirical meaning” could be interpreted more flexibly than “verifiability.” “Empirical meaning” might not provide a clear-cut criterion, leading to ambiguity about what constitutes a meaningful statement. In contrast, the verifiability criterion had a more concrete empirical foundation, even if it was overly strict in some ways.
In short, changing to the “verifiability theory of empirical meaning” could weaken the logical positivists’ original goal of eliminating meaningless metaphysical claims by offering a broader and more flexible framework for what constitutes meaning in empirical terms. This could invite more theoretical, less directly verifiable statements into the realm of meaningful discourse, which might go against the strict empirical focus the Logical Positivists advocated.

You’re absolutely right! If the verifiability theory were changed to the “verifiability theory of empirical meaning,” the classic objection that the theory itself is meaningless (because it couldn’t be empirically verified) would no longer apply.
Under the original formulation of the Verifiability Theory of Meaning, one of the key criticisms was that the criterion of verifiability itself is not verifiable. The theory proposed that a statement is meaningful only if it can be empirically verified, but critics argued that the verifiability criterion, as a proposition, couldn’t be verified through experience or observation, leading to a kind of self-referential problem—making the theory self-defeating.
If the theory were reformulated as the “verifiability theory of empirical meaning,” this self-defeating problem might disappear. Here’s why:
- Empirical Meaning as a Broader Framework: By introducing “empirical meaning,” the theory could avoid the self-referential issue. Instead of insisting that only verifiable statements are meaningful, it might suggest that statements are meaningful insofar as they are grounded in empirical observation or could potentially be connected to empirical evidence, even if they can’t be directly tested right now. This framing doesn’t necessarily apply the verifiability criterion to itself, thus sidestepping the problem of verifying the criterion itself.
- A More Flexible Interpretation: With “empirical meaning,” it might be possible to interpret the verifiability criterion in a way that doesn’t require strict, immediate empirical verification for the theory’s own validity. It could allow for statements to be considered meaningful based on a broader range of empirical connections (e.g., they are testable in principle, even if not currently testable). This would neutralize the critique that the verifiability theory is meaningless because it couldn’t be empirically verified.
- Potential for Self-Consistency: The change could give the verifiability criterion more flexibility and prevent it from being a target of the very objection it aimed to solve. It would now be seen as a general guideline for empirical meaning, not a strict, self-asserting rule that must apply to all statements, including itself.
In sum, shifting to a “verifiability theory of empirical meaning” would indeed resolve the specific objection that the verifiability theory is itself meaningless by loosening the rigid demands of the original version and shifting to a more practical, less self-referential framework. The objection that the verifiability theory can’t be verified would no longer apply because the theory would not demand direct empirical verification of all statements, including its own.
