This question already has an answer here:
I'm not talking about religion. Imagine certain Ancient Egyptian writing or old Chinese poem or phrase by Shakespeare, comment on life being very short or we being puppets in the theater of life. Some people seem to think that just because this is very old, than mere repetition of the phrase has a certain authority or importance or power above and beyond what some brilliant philosopher at present might say. There is a kind of glorification of it beyond the thought expressed, mere reason that it's old or very old. So these people constantly quote this or that ancient writing as if it's proof of veracity of certain view. Is there a word for these people or this act?
Edit: thank you, it's similar to the other question, consider this solved.
