Return to the original meaning of the word.
It was needed to explain "what is an abstraction" in the engineer's intellectual production techniques, and then even more broadly in the process of translating it into English.
I did not know it at the time, but in 2021 I learned that Heidegger used the same method in Building, Living, Thinking and also called such an approach "thinking" and said that it is inevitable for human existence. This is similar to how I realized that Einstein said almost the same thing after I finished writing a chapter.
