What limitation does the concept of "strong verifiability" possess?

The concept of "strong verifiability" is associated with the verification principle in logical positivism, which asserts that a statement is meaningful only if it can be definitively verified through empirical observation or logical proof. One key limitation of this approach is that it can become too restrictive. Under strong verifiability, a wide range of meaningful statements, especially those in ethics, metaphysics, and even some scientific theories, may be dismissed if they cannot be verified through direct observation or empirical evidence.

For instance, ethical statements like "murder is wrong" or metaphysical claims such as "the universe has a purpose" cannot be empirically verified, leading proponents of strong verifiability to reject them as meaningless statements. This results in a narrowing of what can be considered meaningful discourse, effectively excluding vast areas of human experience and inquiry that do not adhere to empirical verification. Thus, while the intent may be to promote rigor in philosophical discussion, the practical implications can limit the richness and complexity of human thought and dialogue.
