This paper focuses on the philosophical ground constituted between “Language” and “Logic”, which should be coined as “synthetic ways” because the synthesis of “Logic” and “Language” is  “the science of Logic”  as one of the synthetic ways of synthesis by the “mind”.  When we look into the historical development of this synthesis process, we see very different synthetic operations, compared with those which are in modern times and in terms of fundamental dynamics. Thus, this article aims to show that the dynamic of “time” is in interaction with the dynamic of “motion” –so the dynamic of “changing”.  It also aims to how that that the quality of the interaction between those dynamics is coming true because of the difference in understanding the category of “quantity” by the views of different philosophers. For instance, according to Aristotle, categories belong to being; but in Kant, categories belong to the mind that will perceive the being. Hence, this study aims to show the difference in understanding the “being” and the one who perceives it from a different perspective.
