I seem to remember learning somewhere, maybe in adult bible study at some point, that written materials were often not trusted as much in the ancient world due to the fact that you could not quiz and interrogate them the way you could a speaker.
The critics of 'oral tradition' – and sadly Bart Ehrman is one of them – invariably bases their argument on the assumption that the Tradition works like the 'Telephone Game'. It's a false analogy to start with. There are plenty of online resources that drive a horse and cart through those arguments.
Oral tradition is not just people 'telling stories round the camp fire'. Oral Cultures were much more sophisticated in the preservation and transmission of stories that were of vital cultural importance.
Also, unlike the Telephone Game, it's not a single line of transmission, it's within groups, from families up to entire cultures, and there are checks and balances and, as you say, listeners could 'quiz and interrogate' the speaker. What can you do with a piece of paper?
I think, me working from memory here, that there's a common assumptions that because, having grown up in a written transmission milieu, that oral transmission is somehow defective and unreliable, whereas Oral Cultures had far better means of store and recall, which we lost as we gave away those skills in favour of new technologies.
(Illustrated manuscripts, for example, were
aides memoire to enable the reader to memorise the page for oral recitation.)
It's hard to recognise the importance of oral transmission, and yet it was central to cultural life.
Services were performed in the synagogues and temples, and
sacra doctrina was read, and people listened. But people didn't have
sacra doctrina at home, nor was there a 'personal reading' culture as we have it today.
Reading, even personal reading,
was done aloud! I have a reference to one of the Fathers, in the 4th century or later, in which it was remarked that so-and-so read
in silence, which was startling to the observer! Who does that?!
(Being the designer for a now 40-year old public poetry programme, I would happily argue that poetry read aloud is often more profound and effective than poetry read in silence in a quiet corner.)
I am of the opinion that the argument that regards a written source as somehow a superior guarantor of veracity is somewhat anachronistic. We make it because we rest on literary dependence. Dependence on the written word is our weakness, not theirs.
Also I don't think people carried writing implements around on the regular like in more recent times.
I rather agree. It was be as required.
So in conclusion it's hard to say yay or nay, only that AFAIK there is no clear evidence to support the speculation of contemporary notetakers.
None.
