What picture of language, meaning, and understanding do we have on display in Augustine’s The Teacher? Perhaps a summary of The Teacher is best for answering that question.

The Teacher takes the form of a dialogue between Augustine and his sixteen-year old son, Adeodatus. The work is one of Augustine’s earliest, a fact he makes plain in Book IX of Confessions, wherein he reminiscences fondly about his late son.

ⁱ The purpose for the dialogue is not immediately discernible. It begins by focusing on the problem between human speaker and his relation to signs and language, but it soon “quite logically leads to a consideration of the origin of man’s intellectual knowledge,” as translator of the dialogue Robert P. Russell observes.ⁱⁱ Knowing that later generations will read his works, like The Teacher, and undoubtedly struggle to understand them, Augustine writes at the end of his life Retractions. Retractions, despite its name, is not simply a collection of retractions and improvements on previous statements; it’s also an interpretive guide to the works of Augustine from the man himself. It’s in Retractions that he discloses to us the purpose of The Teacher, saying: “During this same period I composed a book called The Teacher where, after some discussion and inquiry, we find that it is God alone who teaches men knowledge, all of which is also in accord with what is written in the Gospel: ‘One is your teacher, Christ.’”ⁱⁱⁱ The goal of the work therefore is twofold: to discover where human knowledge comes from (Christ), and to evoke trust in the source of that knowledge.

The dialogue begins with Augustine asking Adeodatus a series of probing questions about the purpose of spoken language. After a quick back-and-forth (which becomes characteristic of the work as a whole), Adeodatus concludes, under his father’s guidance, that the purpose of spoken language is twofold: to teach and to remind. Yet, Adeodatus still has some reservations about this understanding of language, particularly as it relates to the examples of song and prayer. Singing, for example, has nothing to do with teaching or reminding; people seem, more often than not, to sing because they simply find pleasure and solace in it. Augustine grants this point, but suggests that songs have no relation to teaching or reminding because, properly speaking, they do not constitute verbal speech. His distinction is ingenious: songs necessarily require melody for their operation; melody is independent of verbal speech (e.g., humming, playing an instrument, etc.); therefore, singing does not qualify as verbal speech. Adeodatus concedes to his father, but argues for an exception: prayer. Adedoatus would willingly concede to Augustine’s account of the purpose of language “were it not for the difficulty that, in praying, we are actually speaking, and yet it is not right to believe that God is taught anything by us, or that we recall something in His mind.”^iv In reply, Augustine says that prayer, properly understood, does not require language. Instead, he argues, true and authentic prayer is always inarticulate. True prayer occurs within the interior part of the human; it arises within the heart or “inner chamber,” where the Lord wishes to dwell (cf., Mt 6:6). This is not to deny, of course, that prayer can be spoken; but, when it is spoken, it is “in order that men may hear and, by this verbal reminder, fix their thoughts upon God by a unity of heart and mind.”^v Prayer, therefore, is not a species of spoken language. If it were, then it would necessarily teach or remind, just as all spoken language does.

After establishing spoken language’s twofold purpose, Augustine then asks Adeodatus if he agrees that words function as signs for things (or, “realities” as he elsewhere calls them). His son responds affirmatively. Yet, after challenging him to define the realities to which the words nihil and si respectively refer, neither Augustine nor Adeodatus is able to provide an account. They briefly wonder about how such words can be so readily understood and yet not refer to anything at all, but Augustine quickly drops the issue, telling his son that nihil and si must in the end refer to inner states of the mind, which are unobservable. Subsequently, he asks Adeodatus to name the reality to which the preposition ex refers. After trying to define ex by means of another preposition (de) Augustine stops Adeodatus, saying: “I am not asking you to substitute one familiar word for another equally familiar… I am looking for the one thing itself, whatever it is, which is signified by these two signs.”^vi Observing that they may have reached a dead end, Adeodatus and Augustine conclude that there must be certain realities that can only be defined ostensively; e.g., pointing at an object. Gestures and bodily movements, therefore, function as signs in the same way that words do.

But words and gestures can also signify other signs, according to Augustine; they do not always name things. He says, “there are signs that manifest signs, and signs that manifest things that are not signs.” Moreover, there are even things that “can be manifested without signs.”^vii In this latter case, human beings perform certain activities that simply manifest the thing/reality itself, without having further need to provide signs. For example, if someone were to ask another what dancing is, she could simply respond by dancing, and thereby demonstrate the thing itself. From this discussion, Augustine deduces that there must be a “three-fold division of signs”^viii: signs that refer to other signs, signs that names things, and things which require no sign at all.^ix Augustine and Adeodatus soon set out to investigate each of these sign groups; and through a series of difficult questions, they learn that this first group of signs can be further subdivided into two. The first subgroup comprises signs that “cannot be signified by those signs which they signify,”^x an example being the word “conjunction.” “Conjunction” names things such as “and,” “or,” “for,” etc. Yet in naming these words, “conjunction” is not reciprocally named. The second group, on the other hand, comprises signs that can be reciprocally signified. Augustine gives the example of “word” and “noun.” Through a long, and rather tedious, argument, Augustine contends that all words (i.e., all parts of speech) are, on closer examination, nouns. Since each word names a thing, each word is, by definition, a noun. The only difference between “words” and “nouns” is cosmetic—“words come from ‘striking’, and nouns from ‘knowing’, so that the former has earned its name because of the ear, the latter, because of the mind.”^xi

Augustine continues his reflection on signs, moving the discussion toward the latter two subgroups (viz., signs that name things, and things manifested without signs). Concerning the countless examples of this third subgroup (i.e., things signified without signs), Augustine says: “For, apart from the numerous plays performed in every theater by actors who play their part by enacting the events themselves, without using signs, does not God, as well as nature, exhibit and manifest to the view of all, and just as they are, the sun and the light which covers and clothes all the things around us…?”^xii From the second subgroup, Augustine argues that we learn the relative unimportance of words. Since words are mere signs for realities, “the realities signified are to be valued more highly than their signs.”^xiii And thus Augustine says: “[T]he most I can say for words is that they merely intimate that we should look for realities; they do not present them to us for our knowledge.”^xiv This admission leads Augustine to conclude that his earlier account of the purpose of language was wrong: words serve only mnemonic functions, not didactic ones. On his view, words can evoke in the mind of the hearer a recollection of the reality they name, but they can never improve upon the knowledge of the hearer. This is because words are only meaningful insofar as one already knows the things to which they refer. Without such prior knowledge, words are utterly meaningless. Augustine says: “So by means of words we learn only words, or better, the sound and noise of words. For if something cannot be a word unless it is a sign, I still cannot recognize it as a word until I know what it signifies, even though I have heard the word… It is perfectly logical and true to conclude that whenever words are spoken, we either know what they mean or we do not.”^xv Words, therefore, are mere mnemonic devices.

Admitting that words carry no didactic function, but serve only mnemonic purposes, naturally leads Augustine to conclude that understanding is fundamentally something that occurs within the individual’s mind. He says: “But as for all those things which we ‘understand,’ it is not the outward sound of the speaker’s words that we consult, but the truth which presides over the mind itself from within, though we may have been led to consult it because of the words.”^xvi But this raises the question, “Does this inner consultation not ultimately suggest that the individual is his or her own teacher?” Augustine anticipates this question, and responds to it by arguing that the true inner person the individual consults is not himself or herself, but rather the Lord. He says: “Now He who is consulted and who is said to ‘dwell in the inner man,’ He it is who teaches us, namely, Christ, that is to say, ‘the unchangeable Power of God and everlasting wisdom.’ This is the Wisdom which every rational soul does indeed consult.”^xvii No one, therefore, can claim to teach others by means of his or her words—“For he is being taught, not by my words, but by the realities themselves made manifest to him by the enlightening action of God from within.”^xviii By divine illumination, the Lord grants understanding to the individual.

The Teacher concludes with Adeodatus summarizing all that he has learned throughout the discussion. First, under the guidance of his father, he has learned that words serve only mnemonic functions; their role is to stimulate the hearer to recall and reflect internally upon the realities to which words name.^xix Second, and most importantly, he has learned that understanding is ultimately and finally a divine miracle. He says: “But as to the truth of what is said, I have also learned that He alone teaches who made use of external words to remind us that He dwells within us.”^xx The real purpose of language, therefore, is ultimately theological: to trust in the Lord, the one who alone grants understanding to humankind.

When writing anything important—whether an email, a text, a lesson plan, an essay, a blogpost—there’s perhaps nothing more difficult than knowing where to begin. It should hardly surprise us therefore to learn that even a great mind like Ludwig Wittgenstein struggled immensely to begin his famous Philosophical Investigations—affectionately known by his devotees as “the Investigations.” According to theologian Fergus Kerr, knowing how to begin the Investigations “preoccupied Wittgenstein for many years.”ⁱ Now Kerr’s claim may be exaggerated, but it’s nonetheless telling: when writing the Investigations, the beginning mattered for Wittgenstein, and rightfully so, for what he would say at the start of the work would inevitably determine all that would follow.

It’s no accident then that Wittgenstein chose to begin the Investigations by quoting a figure who needs no introduction in the West. That figure is Saint Augustine of Hippo. As for his quote, well, it needs no real introduction either: for despite being casually written with the putative intention of expressing a reflective, but nonetheless passing observation of a juvenile’s emerging first-person awareness and incipient communicative skills, the remark has since been taken by many as a full-fledged account of language, meaning, and understanding. Augustine writes:

When grown-ups named some object and at the same time turned towards it, I perceived this, and I grasped that the thing was signified by the sound they uttered, since they meant to point it out. This, however, I gathered from their gestures, the natural languages of all peoples, the language that by means of facial expression and the play of eyes, of the movements of the limbs and tones of voice, indicates the affections of the soul when it desires, or clings to, or rejects, or recoils from, something. In this way, little by little, I learnt to understand what things the words, which I heard uttered in their respective places in various sentences, signified. And once I got my tongue around these signs, I used them to express my wishes.ⁱⁱ

Augustine, Confessions

That so many have, in my estimation, misread this account as Augustine’s exhaustive philosophical account of language, meaning, and understanding is something of an injustice; a literary one to be sure, and thus perhaps a minor one, but an injustice all the same. But so it goes with writing and all forms of communication: all communication is liable to abuse and misunderstanding. Whenever we write, whenever we speak, whenever we gesture, we take a risk. It’s why writing anything at all is difficult. It’s also why it matters that we try to get it right. It’s precisely why the beginning of the Investigations mattered so deeply to Wittgenstein. He wanted to get it right.

And thus the question arises: Why did Wittgenstein begin his work with Augustine? According to the American philosopher Norman Malcom: “[Wittgenstein] revered the writings of St Augustine. He told me he decided to begin his Investigations with a quotation from the latter’s Confessions, not because he could not find the comment stated as well by other philosophers, but because the conception must be important if so great a mind held it.”ⁱⁱⁱ Malcom’s comment is instructive: Wittgenstein admired Augustine, and, contrary to popular reception of the Investigations, he had no desire to dismiss, or even “attack” (to put it in somewhat colloquial terms) the saint’s so-called positions; for all Wittgenstein’s whipping boys (a certain scene with a poker and Karl Popper comes to mind)—well, Augustine was just not one of them. Rather for Wittgenstein, the problem with “Augustine’s picture of how he learned language as a child,” writes literary critic Toril Moi, “is not so much wrong as premature: only someone who already knows what it means to point, and what it is to name something, will be able to follow such instructions.”^iv Moi’s point about Wittgenstein’s use of Augustine in the Investigations seems textually indisputable (see PI §4; cf., §32). Augustine’s account is missing something important, and Wittgenstein wants to improve upon it. And since it is Augustine in question, the need to get it right is consequentially momentous.

But does Wittgenstein get it right? Does he, in other words, dramatically improve upon Augustine in the way so many imagine? Does he lead us out of the tenebrous Augustinian cave?

Well… kind of, but not totally. It seems to me that Wittgenstein’s improvement on Augustine is in a certain way insufficient. I say that not because the Wittgensteinian improvement is inherently deficient (it’s not—I’ll argue to the death that it’s not), but rather because it has unwittingly reduced the contributions of one of the most prolific authors in Western history—the Doctor Gratia, the author of the modern autobiography, the greatest theologian of the West (debate me all ye Thomists!)­­­­—to a mere passage. And so it goes that the readers of the Investigations can now say: “Augustine’s picture of language” or the “Augustinian picture of language,” as if that somehow encapsulates all that Augustine had to say about language. Ah, what a shame. I mentioned literary injustices earlier, and now look where we are: we’re back.

Few have written more than Augustine, and few have had a more omnivorous mind than he. Which means, for one, that even when he’s wrong, he’s interestingly so (a point Wittgenstein knew well enough); but two—and this is what’s important—it means that he probably wrote more on language, meaning, and understanding than a mere passage or two. And he did, of course—as theologian Fergus Kerr writes: “It is not clear whether Wittgenstein knew how much more complicated Augustine’s theory of language was: whether, for example, he had read the De Magistro.”^v You see, it’s Wittgenstein’s unfamiliarity with the complexity of De Magistro (Eng. The Teacher), his unfamiliarity with the complexity of Augustine’s thoughts on language, meaning understanding, that leads me to say that his improvement on Augustine is insufficient.

But in Wittgenstein’s defense: who really can read the entire oeuvre of a man like Augustine? Life is short, and there’s far more important work to be done. Wittgenstein’s beginning is therefore forgivable. Which means perhaps we can all say, “Wittgenstein, as much effort and time as you put into thinking about how to begin your magisterial Philosophical Investigations, though it may be inadequate, it’s commendable, and we thank thee.”

Eh, that’s boring. It’s also intellectually lazy. Instead, let’s do something far more interesting. Let’s speculate for a moment about what Wittgenstein would have thought about Augustine’s more extensive treatment of language, meaning, and understanding in The Teacher had he chosen to read it. Now that would be interesting. It would also help us say something more definitive about Wittgenstein’s choice to begin with Augustine in the Investigations.

So, let’s begin there.
