Yeah but Phaedrus was an implicit critique of Socrates so I don't buy the idea of taking Socratic approach at face value (and then in the 20th century many critical interpetations of Phaedrus in turn). A lot has happened since that time that has complexified notions of learning, and it strikes me as idiosyncratic to of the OP to cite Socrates as the solution instead. It is like ignoring the rest of the extant literature, including scientific literature on pedagogy and cognition, why do that? It is not justifiable from a STEM pov.
