The concept of meaning seems to be diminished in recent trends of TEFL in Japan. The diminishment is buttressed by the combination of objectivist semantics, objective tests, neo-liberalism and one-dimensional objectivism. Against the diminishment, this paper offers a new concept of meaning by introducing Integrated Information Theory by Tononi in neuroscience and supplementing it with the theory of meaning by Luhmann in theoretical sociology. In a sharp contract with objectivist semantics that regards meaning as an objectively describable, static, and determinate object, the new concept states that meaning is (1) a subjective experience on an objective physical mechanism; (2) experienced in unification of determinacy of actuality and indeterminacy of potentiality; and (3) a dynamic process. The paper also offers some practical implications.
