This is a start, but logical positivism was an entire philosophical movement, not just a theory of cognitive significance. This--"only statements about empirical observations are meaningful, effectively asserting that all metaphysical statements are meaningless"--appears to be an attempt at formulating the verifiability theory of meaning, which was essential to the Vienna Circle's thinking, but does not exhaust what logical positivism was about. Maybe you could do some more research? The topic is eminently researchable--many books have been written about it. --LMS |
