“Unified science or unity-of-science view: In the philosophy of logical positivism, the doctrine holding that all science share the same language, laws, and method. The unity of language has been taken to mean that either that all scientific statements could be restated as a set of protocol sentences describing sense-data or that all scientific terms could be defined using physics terms. The unity of law means that the laws of the various sciences must be deduced from some set of fundamental laws (e.g. those of physics). The unity of method means that the procedures for supporting statements in the various sciences are basically the same. The unity-of-science movement that arose in the Vienna Circle held to those three unities, and Rudolf Carnap’s ‘physicalism’ supported the notion that all the terms and statements of empirical science could be reduced to terms and statements in the language of physics.”
