-Socrates.
One of the most valid and effective approach of teaching people or passing down knowledge to people is the Socrates philosophical quote which says. “Je ne peux rien enseigner à personne, je ne peux que les faire réfléchir”.
Translated from french it says:
I cannot teach anyone anything, I can only make them think🤔.

Making people to think is most helpful for them since you’re by so doing availing them the chance to think deeply about the subject matter and by extension they putting themselves in the situation. In other words it balloons their mind and sense of reasoning.
