Lukkusu There are two fundamental general categories in logic that must be distinguished. One involves "thinking" and the other "recognition."In "thinking" its format&sbquo method and reasoning&sbquo as well as context and path are called the logic of thinking or conceptual logic. In "recognition&sbquo"reasoning and structure for the purpose of reaching the object of recognition or cognition is the logic of recognition &sbquo or logical cognition As to conceptual logic&sbquo there is formal logic&sbquo which is a study that abstracts the content of thinking and investigates the format of deduction&sbquo and as to logical cognition&sbquo there is epistemological logic that aims at firmly grasping the object of recognition. Since the objective of these two academic disciplines is to share the precision and accuracy of thinking and recognition&sbquo they have become methodologies that associate thinking and recognition in diverse academic fields including mathematics&sbquo philosophy&sbquo literature&sbquo engineering and semiotics&sbquo and their contents have been accumulated historically.
If we logically re-verify thinking and recognition&sbquo however&sbquo the following questions should clearly arise. First&sbquo is there only one "correct logic&sbquo" or are there more than one? Even if there is only one correct logic&sbquo when it is verified against multiple other logics&sbquo do they become consolidated or converge into singularity? Furthermore&sbquo the question leads to whether these very questions can be written down as certain rules by returning them to logical thinking or recognition. This&sbquo in short means&sbquo whether logics experiential nature of inevitability&sbquo thinking and recognition. In other words&sbquo it is bound by the "logic of logic&sbquo" and its conclusion can be said to return to to the judgement that this may be the limit of logic. Therefore&sbquo I believe it is extremely important to describe in writing design thinking and design recognition in terms of design logic or logical design study that complementarily and correlatively establishes design logic or logical design.
