As editors we should be aware of the dichotomy between our-own-stating of our-own-descriptions and our quoting of descriptions of others already published.
If Professfor Hausfleish says in "Journal of Jane Austen Studies" that "Jane Austen's portrayal of life in the English countryside is without any relevant basis." that is quite different from *me* paraphrasing my own understanding of Jane Austen with the reality of English living.
Our own interpretations, while editing, should be as-much-as-possible shelved. We, as expert editors, should know from where to pull those criticisms and interpretations, without creating them afresh with our own words vis-a-vis an appropos paraphrase of some one else's.

We still have an editorial duty to evaluate the reliablility of Professfor Hausfleish and the Journal of Jane Austen Studies. And, if they are not reliable, reject them as inappropriate sources. If they are just personal opinion, that's what they are, inappropriate sources.
