Themes
Logical positivism was a movement without a fixed set of doctrines. The logical positivists held a wide range of views on many matters. Nonetheless, they were all interested in science and skeptical of theology and metaphysics. Early, most logical positivists proposed that all knowledge is based on logical inference from simple "protocol sentences" grounded in observable facts. Many logical positivists endorsed forms of materialism, metaphysical naturalism, and empiricism. (See James Ladyman, Understanding Philosophy of Science, p. 147)
