Logical Positivism is a philosophical movement that emerged in the early 20th century, primarily associated with the Vienna Circle. It emphasizes that meaningful statements must be either empirically verifiable or analytically true, meaning they can be confirmed through observation or are true by definition. This approach rejects metaphysics and traditional philosophy as meaningless, arguing that many philosophical questions do not have empirical answers. Logical Positivism significantly influenced the philosophy of science, promoting a focus on scientific methods and the importance of language in clarifying concepts and theories.
