I was reading an article the other day which started referencing the famous Confucius quote:

Except Confucius didn’t say it – the wording has been misattributed to him. A similar phrase was first noted by Xunzi and it looks like the mistakes happened in the 1960s when Confucius’ writings were publicised more.

I understand why people use quotes in learning; they work as a neat shorthand to describe concepts and ideas which you’re trying to engage people with. As I’ve said before, you have to attribute correctly. If you start an article with a quote I WILL check to see if the person really said it. If they haven’t, you’ll likely have lost me immediately.
