217 Conclusion H ow did the Middle Ages come to construct a notion of mental language quite similar, in certain respects, to that of contemporary philosophers? To answer this question, we identified a multitude of Greek and Latin texts, from Plato through the time of William of Ockham, that feature characteristic expressions evoking, on the one hand, the order of discourse or language and, on the other, the domain of interiority or the mental. (The list “Thirty-six characterizations of interior discourse” recalls the principal expressions.) This varied assortment supplied the raw material of my research at the beginning and circumscribed the corpus with which I worked. The inquiry then revealed how these scattered occurrences could be regrouped into diachronic series that intersect and influence each other in various ways through the centuries. The comparison of human thought to a kind of speech, language, or discourse plays all kinds of roles over the course of this very long period, and even within each stream of transmission, the disputed questions, perspectives, and interests—theoretical as well as practical— are continually repositioned and renewed. As a whole, however, the connections among the many points of the picture thus plotted are sufficiently rich and significant to justify the recognition here of something like a history: the history of what I call the theme of interior discourse. At least the broad outlines of this history are clear. In this matter as in others, medieval reflection finds its sources both in Greek philosophy—which in the wake of Plato and Aristotle had established a technical distinction between logos endiathetos and logos prophorikos—and in the fathers of the church—above all Augustine, who, desiring to discover in man an image of the divine Trinity, had meditated extensively on the interior generation of conscious thought. The encounter of these two traditions in the thirteenth-century university gave rise to a range of precise philosophical discussions on the “mental word,” its ontological status, its role in knowledge, its relation to language, and, especially at the turn of the fourteenth century, on the object of logic, which had become the foundation of intellectual formation. The Ockhamist notion of oratio mentalis, destined for enormous success during the two subsequent centuries, thus took shape.
