Their pupils and their little charges are not nourished and fed by what they learn: the learning is passed from hand to hand with only one end in view: to show it off, to put into our accounts to entertain others with it, as though it were merely counters, useful for totting up and producing statements, but having no other use or currency. 'Apud alios loqui didicerunt, non ipsi secum' [They have learned how to talk with others, not with themselves]
Michel de Montaigne (1991). “The essays of Michel de Montaigne”, Lane, Allen
