Claim. Sang Hun Lee defines logic as the study of the laws and forms of thinking, paralleling how physiological functions in the body are governed by laws and forms.
Elaboration. The framing argument is anthropological: a human being is a dual being of mind and body, and just as the body’s physiological functions operate under laws and forms, so does the mind’s thinking. Blood circulation supplies nutrients through the ‘form’ of circulation under fluid-dynamic laws; nerve signals follow the ‘form’ of transmission under chemical laws; chemical reactions in the blood happen under catalytic laws (Logic). The body is not a chaos of free-floating processes — it is rule-governed.
By analogy, thinking only seems to be unrestricted. In fact, thinking always proceeds under certain forms and laws. Since Aristotle’s founding of formal logic, the discipline has examined the laws and forms common to thinking that contains varied contents; later, Hegelian and Marxist dialectic dealt with the laws and forms of the development of thinking and nature. Lee announces a three-part program for the chapter: (1) outline traditional logic, focusing on formal logic and Hegel; (2) construct Unification logic from the principle-of-creation; (3) evaluate the tradition from that vantage. The mind-body parallelism is not decorative — it sets up the later claim that the laws of thought (especially give-and-take) are continuous with the laws governing the created world, since both flow from God’s Original Image.
