Wat is Waarheid?

Inleiding: ‘n Eed oor iets wat niemand kan definieer nie

Elke dag staan iemand in ‘n Suid-Afrikaanse hofsaal op, dikwels met die regterhand opgelig, en sweer: Ek sweer dat die getuienis wat ek sal aflê, die waarheid, die hele waarheid en niks anders as die waarheid sal wees nie. So help my God. Die woorde kom reguit uit die Strafproseswet van 1977. Hulle klink amper soos ‘n gebed.

Die getuie het heel waarskynlik nog nooit ‘n boek oor die filosofie van waarheid oopgemaak nie. Die landdros dalk ook nie. Tog weet almal in die saal presies wat sopas belowe is. Niemand steek sy hand op en vra: “Edelagbare, watter teorie van waarheid volg ons vandag?” nie

So gaan dit maar met waarheid. Ons gebruik die woord heeldag, en ons is seker van ons saak. “Sê die waarheid,” sê ons vir ‘n kind. “Fopnuus,” tik ons onder ‘n video wat ons nie vertrou nie. As iemand vir ons gejok het, voel ons verraai, en dis nie ‘n te sterk woord nie. Maar vra iemand wat waarheid nou eintlik is, raak ons stil.

Een man het dié vraag hardop gevra, in ‘n gesprek wat elke Christen ken. Pontius Pilatus, die Romeinse goewerneur van Judea, het ‘n gevangene voor hom gehad wat sê Hy het gekom om van die waarheid te getuig. “Wat is waarheid?” vra Pilatus (Johannes 18:37–38). En toe loop hy uit.

Ons gaan nie uitloop nie. In hierdie eerste opstel van die Proloog vat ons die vraag ernstig op: eers soos ‘n filosoof dit sou aanpak, en daarna soos die Bybel dit doen. Aan die einde sal ons sien dat Pilatus iets oor die hoof gesien het wat reg voor sy neus gestaan het.

1. Die eenvoudigste antwoord is ook die oudste

Sowat 350 jaar voor Christus skryf die Griekse filosoof Aristoteles ‘n sin neer wat vandag nog die vertrekpunt is vir byna elke gesprek oor waarheid. In sy Metafisika (boek IV, hoofstuk 7) sê hy, vrylik vertaal:

As jy van iets wat is, sê dat dit nie is nie, of van iets wat nie is nie, sê dat dit is, praat jy die onwaarheid. As jy van wat is, sê dat dit is, en van wat nie is nie, dat dit nie is nie, praat jy die waarheid.

Dit klink amper te eenvoudig vir filosofie. Maar kyk mooi. Daar is twee dinge in die spel: wat jy sê, en hoe die wêreld werklik is. Jou woorde is waar as hulle met die werklikheid ooreenstem. Sê ek daar’s melk in die yskas, en daar is, het ek die waarheid gepraat. Is die yskas leeg, dan nie.

Filosowe noem dit die korrespondensieteorie van waarheid. Korrespondensie beteken eenvoudig ooreenstemming. Waarheid is die ooreenstemming tussen wat ons sê of dink en wat werklik die geval is.

Let op wat die teorie nie sê nie. Dit sê nie jy weet altyd of jou woorde waar is nie. Dalk het jou huismaat vanoggend die laaste melk in sy koffie gegooi en jy weet nog nie daarvan nie. Dan is wat jy sê vals, al glo jy dit met jou hele hart. Die werklikheid wag nie vir jou goedkeuring nie. Juis daarom maak die eed in die hof sin: die getuie belowe dat sy woorde sal klop met wat gebeur het, nie met wat hy wens gebeur het nie.

2. Drie ander antwoorde, en die kern van waarheid in elkeen

Ooreenstemming is nie die enigste teorie nie. Ernstige denkers het minstens drie ander verdedig, en elkeen sien iets raak wat ons nie mag ignoreer nie.

Waarheid as samehang (koherensie). Stel jou voor jy bou ‘n legkaart van duisend stukkies, maar die prent op die deksel is weg. Hoe weet jy waar ‘n stukkie hoort? Waar hy by die stukkies rondom hom inpas. Die koherensieteorie sê ‘n oortuiging is waar as dit inpas in ‘n groter geheel van oortuigings wat mekaar onderskraag.

Daar sit iets in. Ons toets ons oortuigings meestal juis so. ‘n Speurder het selde ‘n video van die moord. Wat hy het, is ‘n klomp leidrade wat net op een manier inmekaar pas. Maar daar’s ‘n probleem. ‘n Goeie romanskrywer kan ‘n storie skryf wat volmaak saamhang en wat nooit gebeur het nie. Samehang is ‘n goeie toets vir waarheid. Dis nie waarheid self nie.

Waarheid as dit wat werk (pragmatisme). In 1907 het die Amerikaanse filosoof William James aangevoer dat ‘n idee waar is as dit in die praktyk werk: as dit ons help om ons pad te vind, iets te voorspel, te lewe. Dis die pragmatiese teorie.

Ook hier is ‘n kern van waarheid. Ware idees werk gewoonlik. ‘n Brug wat op die regte berekeninge gebou is, bly staan. Maar hier is ook ‘n kraak. Party leuens werk uitstekend, altans ‘n ruk lank. Die swendelaar se storie het pragtig gewerk; jou ouma se spaargeld is in sy sak. Dat iets werk, maak dit nie waar nie. Dis eerder andersom: dinge werk gewoonlik omdat hulle waar is.

Waarheid as ‘n leë woord (deflasionisme). In die dertigerjare gebruik die logikus Alfred Tarski ‘n voorbeeld wat beroemd sou word: “Sneeu is wit” is waar as, en slegs as, sneeu wit is. Party filosowe het daaruit afgelei dat die woordjie “waar” eintlik niks byvoeg nie. “Dis waar dat sneeu wit is” is maar net ‘n lang manier om te sê “sneeu is wit”. Hulle noem dit deflasionisme, omdat dit die groot woord waarheid soos ‘n ballon laat leegloop.

Hierin is hulle reg: ons nie eers ‘n filosofiese teorie nodig het voordat ons iets waar mag noem nie. Die getuie in die hof het nie een nodig nie. Maar kyk weer na Tarski se sin. Die tweede helfte, as sneeu wit is, wys reguit na die wêreld. Selfs die teorie wat waarheid wil laat leegloop, staan nog op die ou grond: woorde moet met iets ooreenstem.

En so is ons terug by Aristoteles. Deur samehang kom ons dikwels agter wat waar is. Dat iets werk, is dikwels die gevolg daarvan dat dit waar is. Maar wat waarheid is, bly die eenvoudige ou ding: woorde wat klop met wat is. Dis ook wat elkeen van ons glo sodra ons vir iemand sê: “Jy lieg.”

3. Maar waarmee stem die werklikheid ooreen?

In die Middeleeue is Aristoteles se gedagte in ‘n kort Latynse formule saamgevat wat Thomas van Aquino (1225–1274) beroemd gemaak het: veritas est adaequatio rei et intellectus. Waarheid is die ooreenstemming tussen die ding en die verstand.

Maar Thomas voeg iets by wat Aristoteles nie gesê het nie. In sy Summa Theologiae (deel I, vraag 16) wys hy daarop dat die ooreenstemming in twee rigtings loop. My gedagtes is waar as hulle met die dinge ooreenstem. Maar die dinge self is “waar” omdat hulle ooreenstem met ‘n ander verstand: die verstand van God, wat hulle uitgedink en gemaak het. ‘n Tafel is ‘n “egte” tafel omdat hy klop met die plan in die skrynwerker se kop. Die skepping is “waar” omdat dit klop met die gedagtes van die Skepper.

Dit klink dalk na ‘n vrome byvoegsel. Eintlik los dit ‘n raaisel op wat ons moderne mense selde raaksien. Waarom sou die werklikheid hoegenaamd kenbaar wees? Waarom het die dinge ‘n vorm wat ons verstand kan vasvat, sodat ‘n kind wat leer tel en ‘n fisikus wat ‘n vergelyking neerskryf, albei iets beetkry wat regtig daar buite is?

Die Bybel gee die antwoord in die eerste hoofstuk van Johannes. Alles het deur die Woord ontstaan (Johannes 1:3), en dieselfde Woord is die ware lig wat elke mens verlig (Johannes 1:9). Die orde in die wêreld en die lig in ons verstand kom uit een bron. Herman Bavinck het sy hele leer oor kennis later op presies dié grond gebou: die Woord wat die wêreld gemaak het, is ook die Woord wat ons verstand verlig, en daarom pas die een by die ander. Ons gedagtes kan met die dinge klop, omdat die dinge eers met God se gedagtes klop.

In die volgende opstel sal ons sien hoe nederig ons hieroor moet bly. Ons kennis is nie God se kennis nie. Maar onthou die beeld: waarheid begin nie by ons nie.

4. ‘n Uitstappie na die naam van hierdie webwerf

Hierdie projek heet Aletheia, die Griekse woord vir waarheid. Dit is dus gepas om na die woord self te kyk.

A-lētheia bestaan uit ‘n ontkennende voorvoegsel (a-, soos in “a-teïs”) en ‘n stam wat met vergeet en verborge wees te make het. Die Duitse filosoof Martin Heidegger het in 1927 voorgestel dat die Grieke waarheid dus eintlik as “onverborgenheid” verstaan het: waarheid is wanneer iets uit die verborgenheid tree en homself wys.

Dis ‘n pragtige beeld. Dit voel soos die oomblik wanneer die mis van die Kaapse Vlakte af oplig en Tafelberg skielik net daar staan, soos hy al die tyd gestaan het. Maar ons moet eerlik wees. Taalkundiges is nie oortuig dat die Grieke die woord so gehoor het nie, en Heidegger self het in ‘n laat opstel (1964) toegegee dat die gewone Griekse begrip van waarheid nie “onverborgenheid” beteken het nie. Ons leen dus die beeld, maar ons bou nie ons huis daarop nie.

Daar is ‘n vaster fondament. Dis ouer as die Grieke, en dis Hebreeus.

5. Emet: waarheid wat jou gewig kan dra

Die Hebreeuse woord wat in die Ou Testament gewoonlik met “waarheid” vertaal word, is emet. Dit kom van ‘n stam wat beteken: vas wees, stewig wees, betroubaar wees. Uit dieselfde stam kom ‘n woord wat ons elke Sondag sê sonder om eers daaroor na te dink: amen. Dit staan vas. Dit is so.

Emet is waarheid wat jou gewig kan dra. Dink aan ‘n leer teen ‘n muur. Jy vra nie eers of die leer ‘n “akkurate voorstelling” van ‘n leer is nie. Jy vra: sal hy my dra? ‘n Ware vriend, in die Hebreeuse sin, is nie bloot iemand wat nie vir jou lieg nie. Dis iemand wat jou dra.

Daarom vertaal ons Bybels emet dikwels nie met “waarheid” nie, maar met “trou”. Wanneer God op die berg by Moses verbygaan en sy eie Naam uitroep, beskryf Hy Homself as barmhartig en genadig, geduldig, en ryk aan liefde en emet (Eksodus 34:6). Hier lees ons Afrikaanse Bybels “trou”. Dis die kern van God se selfbeskrywing: Hy is die Een wat sy woord hou.

Lê dit nou langs Aristoteles. Vir Aristoteles is waarheid wanneer woorde klop met dinge. Vir die Hebreeuse Bybel is waarheid ook wanneer dade klop met woorde, wanneer die belofte en die nakoming ooreenstem. Dis nie ‘n ander soort waarheid nie. Dis dieselfde ooreenstemming, net persoonlik. ‘n Leuenaar se woorde klop nie met die wêreld nie. ‘n Ontroue mens se lewe klop nie met sy woorde nie. God se woorde klop altyd met die wêreld, want sy woorde het die wêreld gemaak. En sy dade klop altyd met sy woorde, want Hy is getrou.

Die Bybel weet dus nie minder as die korrespondensieteorie nie. Dit weet meer.

6. Die Woord vol waarheid

Vroeg in Johannes se Evangelie staan ‘n sin wat doelbewus na Eksodus 34 terugkyk: “Die Woord het mens geword en onder ons kom woon. Ons het sy heerlikheid gesien… vol genade en waarheid” (Johannes 1:14). Baie uitleggers hoor hier die eggo van “liefde en trou”. Wat God op die berg oor Homself gesê het, word nou sigbaar in ‘n mens.

Later in dieselfde Evangelie sê Jesus iets wat geen filosoof ooit van homself sou sê nie: “Ek is die weg en die waarheid en die lewe” (Johannes 14:6). Nie: Ek ken die waarheid nie. Ook nie: Ek leer die waarheid nie. Ek is dit.

Hoe kan ‘n persoon die waarheid wees? As waarheid bloot ‘n eienskap van sinne is, is Jesus se woorde onsin. Maar as waarheid in sy diepste wese ooreenstemming is, tussen woord en werklikheid, tussen belofte en daad, tussen wat God is en wat God sê, dan is Jesus die plek waar al daardie draadjies bymekaarkom. In Hom is God se Woord en God se wese een. Hy is God se amen, soos Paulus sê: al God se beloftes het in Hom hulle “ja” gekry (2 Korintiërs 1:20).

Daarom kan Jesus ook bid: “U woord is die waarheid” (Johannes 17:17). God se woord is nie waar omdat dit toevallig korrek is nie. Dit is waar omdat Hy wat dit spreek, getrou is.

7. Terug na Pilatus

Nou kan ons teruggaan na die verhoorsaal.

Die Ortodokse skrywer David Bentley Hart wys in Atheist Delusions (2009) op iets wat ‘n mens maklik oor die hoof sien. Vir enige toeskouer in die antieke wêreld sou dit glad nie moeilik gewees het om te sien aan watter kant die waarheid in daardie toneel lê nie. Aan die een kant staan ‘n Romeinse goewerneur met mag oor lewe en dood. Aan die ander kant staan ‘n gegeselde gevangene van wie niemand weet waar Hy vandaan kom nie. In ‘n wêreld waar die werklikheid gemeet word aan wie die mag het om te oordeel en dood te maak, het Pilatus se vraag nie eintlik ‘n antwoord nodig gehad nie. Hy het dit gevra, sê Hart, sonder om ‘n antwoord te verwag of nodig te hê (my vertaling).

Dit is die eintlike gevaar in Pilatus se vraag. Dis nie ‘n eerlike filosofiese vraag nie. Dis die vraag van iemand wat meen mag het die laaste woord, en “waarheid” is maar net ‘n ander naam vir wie wen. In die derde opstel sal ons sien dat ons eie tyd presies dié vraag weer vra, net met beter tegnologie.

Maar die Evangelies is nie geskryf deur toeskouers wat gesien het wie gewen het nie. Hulle is geskryf in die lig van die opstanding, en die opstanding keer die betekenis van hierdie toneel heeltemal om. Die man met al die mag het gevra wat waarheid is. Die man sonder enige mag was die waarheid. Pilatus het “wat?” gevra, terwyl die antwoord op “wie?” voor hom gestaan het. Die Middeleeue het al hiermee gespeel. Skuif die letters van Pilatus se Latynse vraag, Quid est veritas?, rond, en jy kry Est vir qui adest: “Dit is die man wat hier voor jou staan.”

Op hierdie wending rus die hele Proloog. Waarheid is nie minder as die eerlike ooreenstemming tussen woorde en dinge nie. Ons gaan dit verdedig, en ons gaan dit nodig kry. Maar waarheid begin nie by ons woorde nie. Dit begin by Iemand wat getrou is, wie se gedagtes die wêreld gemaak het, en wie se Woord vlees geword het.

8. Wat ons nog nie gesê het nie

Hierdie opstel het net een vraag beantwoord: wat is waarheid? Die moeiliker vrae staan nog oop.

As waarheid by God se verstand begin, kan ons swak en gevalle verstand dit dan werklik ken? Dis die vraag van die tweede opstel. En as daar net een werklikheid is, waarom lyk dit vandag of elkeen sy eie waarheid het? Dis die derde. Die vierde vra wat dit beteken om die waarheid te doen, en nie net te weet nie. (Die volle vraag oor hoe ons ken, met al sy tegniese kante, kom eers in Reeks 5 aan die beurt.)

Intussen gaan ons terug na die hofsaal. Die getuie het nog nooit Aristoteles of Thomas gelees nie, en hy het hulle nie nodig nie. Hy belowe dat sy woorde sal klop met wat gebeur het. Dan sê hy nog vier woorde wat die meeste mense seker as ‘n formaliteit afmaak: So help my God. Hy roep die Een aan wat die waarheid is, om hom te help om dit te praat.

Dit som eintlik die hele saak op.

Besprekingsvrae

Die eed: Die getuie sweer by “die waarheid, die hele waarheid en niks anders as die waarheid nie”. Wat is die verskil tussen die drie? Kan iemand net ware dinge sê en tog nie die hele waarheid vertel nie?
Vier teorieë: Watter een van die vier (ooreenstemming, samehang, wat werk, die leë woord) lê die naaste aan hoe jy in die gewone lewe oor waarheid dink? Kan jy aan iets dink wat goed gewerk het, maar nie waar was nie?
Emet: Die Hebreeuse woord vir waarheid beteken ook trou en betroubaarheid. Wie in jou lewe is in dié sin “waar”? Hoe lees jy Johannes 14:6 anders as jy dit in gedagte hou?
Pilatus: Pilatus het gevra sonder om ‘n antwoord te verwag of nodig te hê. Waar sien jy vandag dieselfde houding raak: dat waarheid maar net ‘n ander woord is vir wie die mag het?
Vir die groep: Jesus sê nie “Ek ken die waarheid” nie, maar “Ek is die waarheid”. Hoe sou jy vir ‘n vriend wat nie glo nie, verduidelik hoe ‘n persoon die waarheid kan wees?

What Is Truth?

Introduction: an oath nobody can define

Every day in South African courtrooms people stand up, many with a raised right hand, and promise something they could not define. The wording comes from the Criminal Procedure Act of 1977, and it sounds almost like a prayer: the evidence I shall give shall be the truth, the whole truth and nothing but the truth. So help me God.

The witness has probably never read a book on the philosophy of truth. The magistrate may not have either. Yet everyone in the room knows exactly what has been promised. Nobody stands up and asks, “Your Worship, before I swear, which theory of truth are we using today?”

That is the first thing you notice when you start asking about truth. We use the word constantly, and with great confidence. We tell a child, “Tell the truth.” We type “fake news” under a video we don’t trust. We feel betrayed when someone has lied to us, and betrayed is not too strong a word. But when someone asks us what truth actually is, we go quiet.

One man asked that question out loud, in a conversation every Christian knows. Pontius Pilate, the Roman governor of Judea, had a prisoner in front of him who said, “I came into the world to bear witness to the truth.” Pilate answered, “What is truth?” (John 18:37–38). Then he walked out.

In this first essay of the Prologue we are not going to walk out. We are going to take the question seriously, first as a philosopher would, and then as the Bible does. By the end we will see that Pilate’s question missed something that was standing right in front of him.

1. The simplest answer is also the oldest

Around 350 years before Christ, the Greek philosopher Aristotle wrote a sentence that is still the starting point for almost every conversation about truth. In his Metaphysics (book IV, chapter 7) he says, roughly:

To say of what is that it is not, or of what is not that it is, is false; while to say of what is that it is, and of what is not that it is not, is true.

It sounds almost too simple to count as philosophy. But look at what is happening. There are two things: what you say, and the way things are. A statement is true when it fits reality. If I say “there’s milk in the fridge” and there is milk in the fridge, I have told the truth. If the fridge is empty, I haven’t.

Philosophers call this the correspondence theory of truth. Correspondence simply means “matching”. Truth is the match between what we say or think and what is actually the case.

Notice what this theory does not say. It does not say that you always know whether your statement is true. Perhaps your housemate finished the milk this morning and you haven’t found out yet. Then your statement is false, however sincerely you believe it. Reality does not wait for your permission. That is exactly why the courtroom oath makes sense: the witness promises to make his words fit what happened, not what he would have liked to happen.

2. Three other answers, and what each gets right

Correspondence is not the only theory. Serious thinkers have defended at least three others, and each sees something we should not ignore.

Truth as hanging together (coherence). Imagine building a thousand-piece puzzle without the picture on the box. How do you know a piece belongs in a certain place? Because it fits all the pieces around it. The coherence theory says that a belief is true when it fits into a larger system of beliefs that support one another.

What it gets right: this is mostly how we test our beliefs. A detective solving a case rarely has video of the crime. He has a set of clues that only make sense together in one way. But there is a problem. A good novelist can write a story that hangs together perfectly and never happened. Coherence is a good test for truth. It is not the same thing as truth.

Truth as what works (pragmatism). By 1907 the American philosopher William James was arguing that an idea is true when it proves its worth in practice: when it helps us find our way, predict, live. This is the pragmatic theory.

What it gets right: true ideas usually do work. A bridge built on the right calculations stays up. But here too there is a crack. Some lies work very well, at least for a while. The con artist who steals your grandmother’s savings told a story that “worked” beautifully. Working is not enough to make something true. It is closer to the other way round: things tend to work because they are true.

Truth as an empty word (deflationism). In the 1930s the logician Alfred Tarski used an example that became famous: “Snow is white” is true if, and only if, snow is white. Some philosophers concluded that the word “true” adds nothing at all. Saying “it is true that snow is white” is just a long way of saying “snow is white”. This is called deflationism, because it lets the big word truth down like a balloon.

What it gets right: we don’t need a philosophical theory before we can call something true. The witness doesn’t need one. But look at Tarski’s sentence again. The right-hand side, if snow is white, points straight at the world. Even the theory that wants to deflate truth is standing on the floor of the old idea that words must fit something.

So we are back with Aristotle. Coherence is often how we discover what is true. Usefulness is often a result of truth. But what truth is remains the plain, old thing: words that fit what is. It is also what most of us believe every time we tell someone, “You’re lying.”

3. But what does reality fit?

This is where it gets interesting. The Middle Ages summed up Aristotle’s idea in a short Latin formula that Thomas Aquinas (1225–1274) made famous: veritas est adaequatio rei et intellectus, truth is the match between the thing and the mind.

But Aquinas added something Aristotle had not said. In his Summa Theologiae (part I, question 16) he points out that the match runs in two directions. My thoughts are true when they fit things. But things themselves are “true” because they fit another mind: the mind of God, who thought them and made them. A table is a “true” table because it fits the idea in the carpenter’s head. Creation is “true” because it fits the thoughts of the Creator.

That may sound like a pious add-on. In fact it answers a puzzle modern people rarely notice. Why should reality be knowable at all? Why should things have a shape our minds can grasp, so that a child learning to count and a physicist writing an equation both touch something that is really out there?

The Bible gives the answer in the first chapter of John. All things were made through the Word (John 1:3), and the same Word is the true light that gives light to everyone (John 1:9). The order in the world and the light in our minds come from one source. Herman Bavinck later built his whole account of knowledge on exactly this ground: the Word that made the world is the Word that lights our minds, and that is why the one fits the other. Our thoughts can fit things because things first fit God’s thoughts.

How humble we need to be about this is the next essay’s question. Our knowledge is not God’s knowledge. But hold on to the picture: truth does not begin with us.

4. A detour through the name of this site

This project is called Aletheia, the Greek word for truth. So it is fair to look at the word itself.

A-lētheia is made up of a negating prefix (a-, as in “a-theist”) and a stem connected with forgetting and being hidden. In 1927 the German philosopher Martin Heidegger proposed that the Greeks therefore understood truth as “unconcealment”: truth is when something comes out of hiding and shows itself.

It is a beautiful image. It feels like the moment the mist lifts off the Cape Flats and Table Mountain is suddenly just there, as it was all along. But we should be honest. Linguists are not convinced the Greeks heard the word that way, and Heidegger himself conceded in a late essay (1964) that the ordinary Greek concept of truth did not mean “unconcealment”. So we will use the image, but we will not build our house on it.

There is a better foundation. It is older than the Greeks, and it is in Hebrew.

5. Emet: truth you can put your weight on

The Hebrew word the Old Testament usually translates as “truth” is emet. It comes from a root meaning to be firm, solid, reliable. From the same root comes a word we say every Sunday without thinking: amen. “It stands firm. So it is.”

Emet is the kind of truth you can put your weight on. Think of a ladder against a wall. Your first question is not whether the ladder is an “accurate representation” of a ladder. You ask: will it hold me? A true friend, in the Hebrew sense, is not just someone who doesn’t lie. It is someone who holds.

That is why the Old Testament often translates emet not as “truth” but as “faithfulness”. When God passes by Moses on the mountain and proclaims his own Name, he describes himself as merciful and gracious, slow to anger, and abounding in steadfast love and emet (Exodus 34:6). Most English versions say “faithfulness” there. It is the heart of who God is in his own self-description: he is the One who keeps his word.

Now set this beside Aristotle. For Aristotle, truth is when words fit things. For the Hebrew Bible, truth is also when deeds fit words, when the promise and the keeping match. This is not a different kind of truth. It is the same match, made personal. A liar’s words do not fit the world. An unfaithful person’s life does not fit his words. God’s words always fit the world, because his words made the world. And his deeds always fit his words, because he is faithful.

So the Bible does not know less than the correspondence theory. It knows more.

6. The Word full of truth

John’s Gospel opens with a sentence that deliberately looks back to Exodus 34. “The Word became flesh and dwelt among us, and we have seen his glory… full of grace and truth” (John 1:14). Many interpreters hear the echo of “abounding in steadfast love and faithfulness”. What God said about himself on the mountain becomes visible in a human being.

Later in the same Gospel Jesus says something no philosopher would ever say of himself: “I am the way, and the truth, and the life” (John 14:6). Not: I know the truth. Not: I teach the truth. I am it.

How can a person be the truth? If truth is only a property of sentences, Jesus’s words make no sense. But if truth is at bottom a match (between word and reality, between promise and deed, between what God is and what God says) then Jesus is the place where all those matches meet. In him God’s Word and God’s being are one. He is God’s amen, as Paul says: all the promises of God find their “yes” in him (2 Corinthians 1:20).

That is also why Jesus can pray, “Your word is truth” (John 17:17). God’s word is not true because it happens to be correct. It is true because the One who speaks it is faithful.

7. Back to Pilate

Now we can return to the courtroom.

The Orthodox writer David Bentley Hart points out something easy to miss in Atheist Delusions (2009). To any ancient onlooker it would not have been hard to see where the truth lay in that scene. On one side stands a Roman governor with power over life and death. On the other stands a scourged prisoner of obscure origins. In a world where reality is measured by who may judge and who may kill, Pilate’s question did not really need an answer. He asked it, Hart says, “expecting and needing no reply”.

That is the real danger in Pilate’s question. It is not an honest philosophical question. It is the question of someone who thinks power has the last word, and that “truth” is just a name for whoever wins. Our own time, as the third essay shows, is asking exactly this question again, only with better technology.

But the Gospels were not written by onlookers who had seen who won. They were written in the light of the resurrection, and the resurrection turns the meaning of this scene upside down. The man with the power asked what truth is. The man without power was the truth. Pilate asked “what?” while the answer to “who?” stood in front of him. The Middle Ages already played with this. Rearrange the letters of Pilate’s question in Latin, Quid est veritas?, and you get Est vir qui adest: “It is the man who stands here before you.”

That is the move that carries this whole Prologue. Truth is not less than the honest fit between words and things. We will defend that, and we will need it. But truth does not begin with our words. It begins with Someone who is faithful, whose thoughts made the world, and whose Word became flesh.

8. What we haven’t said yet

This essay has answered one question: what is truth? It has left the harder ones open.

If truth begins in God’s mind, can our weak, fallen minds really know it? That is the question of the second essay. And if there is only one reality, why does it look today as if everyone has their own truth? That is the third. The fourth asks what it means to do the truth, not only to know it. (The full question of how we know, with all its technical sides, waits for Series 5.)

Meanwhile we can go back to the courtroom. The witness has never read Aristotle or Aquinas, and he doesn’t need to. He promises to make his words fit what happened. Then he says four more words that most people probably hear as a formality: So help me God. He calls on the One who is the truth, to help him speak it.

That is not a bad summary of the whole matter.

Discussion Questions

The oath: The witness swears to “the truth, the whole truth and nothing but the truth”. What is the difference between the three? Can someone say only true things and still not tell the “whole truth”?
Four theories: Which of the four theories (correspondence, coherence, usefulness, “empty word”) is closest to how you think about truth in everyday life? Can you think of an example of something that “worked” well but wasn’t true?
Emet: The Hebrew word for truth also means “faithfulness” and “reliability”. Who in your life is “true” in this sense? How does that change the way you read John 14:6?
Pilate: Pilate asked “expecting and needing no reply”. Where do you see the same attitude today: that truth is just another word for whoever has the power?
For the group: Jesus does not say “I know the truth” but “I am the truth”. How would you explain to a friend who doesn’t believe how a person can be the truth?
