Discorrendo con il figlio sedicenne Adeodato, Agostino s'interroga sul ruolo del linguaggio nella relazione educativa, a partire dal rapporto tra le parole e le cose. Il dialogo, qui proposto con testo latino a fronte e note di commento, inaugura la riflessione occidentale sul ruolo del maestro e sul significato dell'insegnamento. Una delle prime, spiazzanti conclusioni è che le parole non insegnano e i maestri non hanno alcun ruolo nella formazione dei discenti. Si tratta, però, di un risultato non definitivo, in un confronto aperto che non intende offrire risposte risolutive, ma affrontare dialetticamente il problema filosofico dell'educazione. Le domande ancora attuali che il dialogo pone costringono a ridefinire il compito del maestro e riportano al centro la necessità di avvicinare il discente al sapere aiutandolo a rintracciare la motivazione nella propria interiorità.
Nelle "Confessioni" Jean-Jacques Rousseau scrisse che la stesura dell'Emilio gli era costata "vent'anni di meditazione e tre anni di lavoro". Si tratta, in effetti, di un'opera suddivisa in cinque libri nei quali l'autore presenta un'ampia varietà di argomenti, dalla teoria della conoscenza all'etica, dalla politica all'esistenza di Dio, all'interno di una cornice principalmente educativa, ricorrendo a diversi registri stilistici e forme letterarie tra le quali, nel quinto libro, tende a prevalere la storia d'amore tra Émile e Sophie. Una tale presentazione sarebbe però lacunosa se non si aggiungesse che, come Rousseau sottolineò successivamente, la filosofia dell'educazione dipendeva dall'assunto antropologico dichiarato nel celebre esordio dell'opera: "Tutto è bene quando esce dalle mani del creatore delle cose: tutto degenera nelle mani dell'uomo". A partire da questa affermazione si snoda l'opera che inaugurò la pedagogia moderna.
Fin dai primi anni dopo l'istituzione della Compagnia di Gesù (1540), con la fondazione e l'avvio dei primi collegi per l'educazione della gioventù (1548), si era fatta largo l'esigenza di disporre di un ordinamento degli studi uniforme, che indirizzasse l'attività d'insegnamento e ne costituisse tratto distintivo. Nel 1599 vedeva la luce l'edizione definitiva della Ratio atque institutio studiorum Societatis Iesu, una grandiosa costruzione pedagogica in grado di rappresentare lo strumento efficace per la formazione delle élites europee dei secoli della modernità e di incidere profondamente nel costume scolastico e nelle pratiche di educazione e formazione fino alle soglie della contemporaneità. La meticolosità delle prescrizioni didattiche, la sua diffusione a tutte le istituzioni dell'istruzione secondaria-superiore, infine la centralità della tradizione classico-umanistica ne fanno una delle chiavi di accesso più efficaci all'organizzazione e alle forme della cultura dei secoli moderni.
