Considering to whom we should attribute a quotation
If I’m quoting, for example, Lord Henry from Oscar Wildes ‘A picture of Dorian Grey”, I should quote Lord Henry. Instead of attributing the line like this: “-Oscar Wilde” I might rather say “Lord Henry from A picture…by Oscar Wilde.” It’s longer, but I am shocked at how infrequently that form seems to be used. It doesn’t make sense to me.
When quoting literature, it seems to me very important that we only attribute to an author what that author attributes to themselves. Because Lord Henry is not the same as Oscar Wilde. I won’t explain why, because it seems so simple and obvious.
I’m not sure whether a formal rule, or academic practice speaks to this point. Is there? Should there be?
