Logical positivism, also called logical empiricism or neo-positivism, represents a renewal of interest in positivist philosophy and is connected to two groups of philosophers, scientists, and mathematicians. The first group is known as the Vienna Circle gathered around Moritz Schlick at the University of Vienna, and include Rudolf Carnap, Otto Neurath  Herbert Feigl, Karl Menger, Hans Hahnand, and Friedrich Waismann; the other group was centered on Society for Empirical Philosophy and the University of Berlin with leading figures like Hans Reichenbach, Walter Dubislav, Kurt Grelling and Carl  Hempel. Austrian philosophers Ludwig Wittgenstein and Karl Popper were, also associated with logical positivism. The goal of logical positivism was to use new advances in logic to distinguish between scientific and unscientific knowledge. They saw science as morally neutral because ideological or moral claims cannot be scientifically tested.
