Criticism on Logical Positivism's Picture of Science and its Proposition

Logical positivism was a quite influential school in the west at the beginning of twentieth century. It advocated the verifiability criterion of meaning, according to which no statement is even meaningful unless either it is in principle possible to empirically verify it or else it is analytic. The positivism attempted to reduce all knowledge to scientific knowledge, all truths to empirical, scientific truths, and all methods of knowing to empirical, scientific methods. The positivism was based on its misreading of the picture of science that science was rigidly objective, rational and empirical. This article, trying to find ways to refute its idea, points out that it's illegitimate for the logical positivism to reduce all knowledge to sci- entific knowledge, all methods of knowing to purely empirical, scientific methods.
