Great article!
Language is really fascinating.
I begin to notice here a certain human curse, the one that forces our specie to know, lose, and rediscover constantly the same ideas.
True. I would call it an insight which reflects reality.
Just as every child has to learn language anew, every human child has to deal with world understanding anew over and over again. All errors repeat themselves exactly as the sublime repeats itself. The speed of this repetition depends on the methods and possibilities.
At some point someone develops a new habitus and gives a term new relevance. For example, in Germany we say: "This is totally acid" and do not mean a corrosive liquid but evaluate a behaviour or a statement of another in a negative way. Just a little silly example :)
Yeah. There are some Germanisms that are common in other languages, such as Dasein, Leitmotiv, Weltanschauung, Zeitgeist, and many others.
Thanks for passing, and for the little silly example...
