I mean, it's a good quote that compactly expresses an important idea, which it does even if Jung didn't say it. but annoying because without an actual attribution I can't in good conscience use it as like... a quote on a slide or a chapter epigraph or something. (or I can but if I attribute it to "anonymous?" or "carl jung supposedly" then people will want to argue about the attribution and not the idea)
@xor I think the annoyance isn't just that I can't use the *text* of the quote, it's that I can't use the quote and also borrow the connotations and authority of Jung (specifically) while I do so. I mean, I can express that same idea with my own words, I don't really need the quote.
@aparrish the whole attribution thing is a murky business; suppose you found it word for word in the contested posthumous english translation of the contested german text of erinnerungen, träume, gedanken heavily rewritten by jaffé and censored by his family ... would you really be happier attributing that to jung?
