The main purpose of this paper is to assert that measurement theory is only a kind of quantitative language. This implies that dynamical system theory is also only a quantitative language, since dynamical system theory is characterized as one of fields of measurement theory. As a consequence of this assertion, Zeno�s paradox is, from the spirit of the language game, clarified in terms of measurement theory.
