The tenets of Logical Positivism

From Ladyman: 1) Science is the only intellectually respectable form of inquiry. 2) All truths are either: (a) analytic, a priori and necessary (tautological) or (b) synthetic, a posteriori and contingent.* 3) So far as knowledge goes, it is either purely formal and analytic, such as math and logic, or it is a kind of empirical science.* 4) The purpose of philosophy is to explicate the structure or logic of science.

However, he argues that acceptance of the best theories in modern science does not require belief in the entities postulated by them, and that the nature and success of modern science relative to its aims can be understood without invoking the existence of such entities. "Van Fraassen defines scientific realism as follows: 'Science aims to give us, in its theories, a literally true story of what the world
