Logical positivists considered metaphysical statements meaningless because they adhered to the verifiability principle, which posits that a statement is cognitively significant only if it is either analytically true (a tautology) or empirically verifiable through observation.12

For the logical positivists, the meaning of a non-analytic statement is defined by the method of its verification—specifically, the set of observable conditions that would determine its truth or falsity. Because metaphysical claims (such as "The Absolute has no history") typically cannot be tested against empirical evidence and are not logically necessary truths, they were deemed to lack factual content.123

While positivists acknowledged that such statements might influence emotions, beliefs, or conduct, they argued that these expressions lack "cognitive meaning" because they do not impart knowledge about the world. Consequently, they viewed metaphysics as a futile attempt to address questions beyond the scope of science, relegating such discourse to the realm of emotive significance rather than genuine representation of reality.132
