Pretty much every single spiritual philosopher has said some version of that (I'm writing a book on this subject right now, heh):
The Buddha (from the Pali Canon, Vinaya Pitaka, Cullavagga 10:4):
āWriting is like a drug that weakens memory.ā
and: āDo not go upon what has been acquired by repeated hearing; nor upon tradition; nor upon rumor... But when you yourselves know: 'These things are good; these things are not blameable; undertaken and observed, these things lead to benefit and happiness,' enter on and abide in them.ā
Confucius (Analects 2:15):
āLearning without thought is labor lost; thought without learning is perilous.ā
Lao Tzu (Tao Te Ching, Chapter 48):
āIn the pursuit of learning, every day something is acquired.
In the pursuit of Tao, every day something is dropped.ā
Jesus (Matthew 16:26):
āFor what shall it profit a man, if he shall gain the whole world, and lose his own soul?ā
Muhammad (Hadith, Sahih Muslim):
āThe worst vessel to fill is the stomach; sufficient for the child of Adam are a few morsels to keep his back straight. If he must fill it, then one-third food, one-third drink, and one-third air.ā
(This Hadith symbolically warns against excessive reliance on external consumption diminishing spiritual clarity and internal balance.)
Rumi (Masnavi):
āThese outward forms are but dust and air;
Seek the reality beyond appearance and form.ā
Krishna (Bhagavad Gita, 2:42-43):
āThose who are attached to pleasure and power, whose minds are drawn away by such things, have no capacity for absorption into higher states of awareness.ā
Sometimes it's good to forget something, commit to written record and let it go. People can carry too much old stuff around in their heads, and it can become burdensome.
Even things like confession, or therapy, leverage this - people letting go of bad things that are hanging around in their memory.
A lot of traditions would strongly disagree with that, myself included. I would imagine you would find a lot of Gnostics who disagree, a lot of "witches" who have been literally burned over the years, and also the aboriginal people of Australia. Well, you wouldn't find so many of them, because those lines of thought have literally been beat out of our human societies in the name of progress. If it's not worthy of being in the oral tradition, it's not worthy of the society, it's not worthy thought. (unworthy thought does not need to be rigorously engaged with.)
Also remember, your conclusion itself is "the devil" - the trap of the analytical mind. :) You will likely do everything you can do avoid the fact that you may be disagreeing directly with the word of the creator as given via various prophets, if you go back to the sources, the command is quite clear, however humans will interpret it: because the command is too simple and terrifying to adhere to. It seems impossible to us that we should indeed, be doing nothing but living in nature in a state of oral tradition and anything outside of that is an unintended state, trusting that energy cannot be destroyed and we are nothing but energy. I don't particularly like it either tbh, hence I'm writing a book about it.
