Ancient Greek's have two separate world for "knowledge": doxa and gnosis. Doxa is the practical, notional ability of doing things, gnosis is the understatement of things.

Today schools push doxa and try to their best to avoid gnosis and even speculation about gnosis. They form useful idiots https://www.theatlantic.com/ideas/archive/2020/08/i-was-usef... or Ford-model stereotypical workers, not acculturated citizens.

As a result modern society is practically ignorant as the middle-age societies, only most does not know that because they think knowledge is only doxa.
