The current lens should keep old ideas in proportion.
Old writing matters.
It shows where the thinking came from.
It shows what has lasted.
It also shows what has changed.
The danger is letting an old idea speak as if it represents the whole current view.
The current lens can help with that.
It can say:
This still feels true.
This was a step toward something clearer.
This needs more context now.
That is not rewriting the past.
It is holding the past in better proportion.
