Moritz Schlick was a German philosopher and physicist, best known as the founding member of the Vienna Circle, a group of philosophers and scientists that promoted logical positivism. Born in 1882, Schlick's work focused on the philosophy of science, emphasizing the importance of empirical evidence and logical reasoning in understanding the world. Schlick's most notable contributions include his ideas on the verification principle, which asserts that a statement is only meaningful if it can be empirically verified. He played a crucial role in shaping modern philosophy, influencing later thinkers and movements, including analytic philosophy and scientific realism.
