Schlick
contemporaryLogical Positivism1882 – 1936
Moritz Schlick (1882–1936) was a German philosopher and the founder of the Vienna Circle, the group that launched logical positivism as a movement. He developed an influential verificationist theory of meaning, holding that a statement is meaningful only if it is in principle empirically verifiable. His work bridged neo-Kantian epistemology and the emerging analytic tradition, and he was a central interlocutor of Wittgenstein, Einstein, and Carnap.
