In such periods, the goal of the translation is to achieve perfect identity with the original, so that the one does not exist instead of the other but in the other's place. とはどういう意味ですか?

@YanYuChen Jeez, are these the kinds of readings lecturers give to translation students?! This is enough to give me a headache 😵. I feel it is better to understand the passage not through grammar, but holistically.

If I understand correctly:

The passage describes the third epoch of translation (in such periods) which states the goal of translation is to achieve what is described as 'perfect identity' with the original work.

'Perfect Identity' is said to be achieved when 'the one does not exist instead of the other but in the other's place'.

So what is the 'one' and what is the 'other'? it is clear that it is talking about an original work (other) and its translation (one).

It is envisioned that a translated work should not exist instead of the original work, but that it should take the original work's place.

What this means practically is elaborated in the following sentences, but I previously read walter benjamin and have some idea, it's about the approach taken in translating a work, of replacement v substitution.
