TY - JOUR T1 - Guest Editor’s Introduction AU - Lewis, James B. JO - Academia Koreana PY - 2004 DA - 2004/1/1 DO - AB - Only by moving grandly on the macroscopic level can we satisfy our intellectual and human curiosities. But only by moving minutely on the molecular level can our observations and explanations be adequately connected. So, if we would have our cake and eat it too, we must shuttle between the macroscopic and the molecular levels in instituting the problem and in explaining it—developing the molecular index structure of general concepts and the general conceptual implications of molecular variables …. We must build up molecular terms; we must break down macroscopic conceptions. For, as matters now stand, the propositional meaning of many macroscopic statements is ambiguous and unclear; the conceptual meaning of many molecular statements is often barren.(C. Wright Mills)
