Logical PositivismandMetaphysics

The principle of verification is the most basic principle of logical positivism. It could be claim that its importance is such that the other principles of positivists are rooted in this principle. The verification means that a statement is meaningless until an empirical study could have done. Since this principle has necessities which the most important principles are the rejection of metaphysics and the subsequent rejection of religious propositions; and the fact that even after the defeats of the principle of verification, some philosophers like R. Carnap attempted, by their own method which is the logical syntax and language, to remove the metaphysics. In this paper, the researcher endeavored to show that metaphysic, in a way that positivist believe, cannot be put aside neither by the principle of verification nor by logical syntax.
