there is a distinction between western-modern pedagogical systems that's like text-based as in a legal method but there is an idea of "pathshala" or "guru shissho"/ "porompora" i mean how masters relayed knowledge to the student by (oral) transmission often by memorising books. so what was taught was always interactive. knowledge was interactive, you spoke with people rather than read texts.

i did until you asked which kind of gave it away

the only things i have read are just excerpts and 1 dialogue by plato fully and mcluhan's medium is the massage but it cannot be considered a book
