A new generation of thinkers who were influenced by Bertrand Russell (1872–1970) and Ludwig Wittgenstein (1889–1951) created a twentieth century version of Auguste Comte’s (1798–1857) nineteenth century intellectual endorsement of science. The term “logical positivism” was coined in 1930 by two supporters: E. Kaila and A. Petzäll, philosophers who were part of the early movement that logical positivism came to represent. The twentieth century positivists Moritz Schlick (1882–1936), Rudolf Carnap (1891–1970), Otto Neurath (1882–1945), and in England, A.J. Ayer (1910–1989) were members of what became known as the “Vienna Circle.”
