PHYSICALISM

See Carnap 's epistemological realism , wherein he held that "every descriptive term in the language of science is connected with terms designating observable properties of things intersubjectively confirmable by observation." The theory is related to what is characterized by scientific empiricists as empirical realism, a form of objectivism wherein the world known is "that which is located in space-time and is a link in the chains of causal relations capable of empirical test" ( Carnap ).
