헤겔의 논리학의 범주들은 자기들에게 적용이 가능합니다. 예를 들어 무언가란 범주가 있다면 그 범주조차 무언가죠. 마치 플라톤의 Form과도 같습니다. 아름다움은 아름다운 것처럼, 헤겔의 논리학의 범주들은 모두 자기들에게 적용이 가능합니다. 다음은 제 구글닥에 써놓은 자기적용성의 논리 재구성과 그 재구성이 실패하는 이유에 대한 dialectic 을 옮겨놨습니다.
Why would each category be applicable to itself? One way to respond is as follows. First, the Logic is a deduction of categories. By categories, I mean ways of thinking. Thinking thinks objects in terms of x, and the Logic is supposed to deduce a complete account of all possible x’s. Second, objects of the Logic are categories. The Logic thinks each x’s. But thinking must think in terms of x. This means that each x is thought in terms of x. So, each category in the Logic is thought in terms of x. This self-application serves as a basis for contradictions by which the Logic unfolds.
This reconstruction’s flaw is that it allows new categories to be thought not in terms of themselves but in terms of previous categories. If, for example, a category of being-for-itself arises, the reconstruction allows it to be thought in terms of, say, something. But my contention is that a contradiction arises through self-application of categories. And if each category need not be thought in terms of itself, the Logic stops unfolding. The reconstruction fails.
