Tetralogue by Timothy Williamson is a philosophy book for the commuter age. In a tradition going back to Plato, Timothy Williamson uses a fictional conversation to explore questions about truth and falsity, knowledge and belief. Four people with radically different outlooks on the world meet on a train and start talking about what they believe. Their conversation varies from cool logical reasoning to heated personal confrontation. Each starts off convinced that he or she is right, but then doubts creep in. During February, we will be posting a series of extracts that cover the viewpoints of all four characters in Tetralogue. What follows is an extract exploring Roxanna’s perspective.

Roxanna is a heartless logician with an exotic background. She would much rather be right than be liked, and as a result she argues mercilessly with the other characters.

Roxana: You appear not to know much about logic.

Sarah: What did you say?

Roxana: I said that you appear not to know much about logic.

Sarah: And you appear not to know much about manners.

Roxana: If you want to understand truth and falsity, logic will be more useful than manners. Do any of you remember what Aristotle said about truth and falsity?

Bob: Sorry, I know nothing about Aristotle.

Zac: It’s on the tip of my tongue.

Sarah: Aristotelian science is two thousand years out of date.

Roxana: None of you knows. Aristotle said ‘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, or of what is not that it is not, is true’. Those elementary principles are fun­damental to the logic of truth. They remain central in contemporary research. They were endorsed by the greatest contributor to the logic of truth, the modern Polish logician Alfred Tarski.

Bob: Never heard of him. I’m sure Aristotle’s saying is very wise; I wish I knew what it meant.

Roxana: I see that I will have to begin right at the very beginning with these three.

Sarah: We can manage quite well without a lecture from you, thank you very much.

Roxana: It is quite obvious that you can’t.

Roxana: It is quite obvious that you can’t.

Zac: I’m afraid I didn’t catch your name.

Roxana: Of course you didn’t. I didn’t say it.

Zac: May I ask what it is?

Roxana: You may, but it is irrelevant.

Bob: Well, don’t keep us all in suspense. What is it?

Roxana: It is ‘Roxana’.

Zac: Nice name, Roxana. Mine is ‘Zac’, by the way.

Bob: I hope our conversation wasn’t annoying you.

Roxana: Its lack of intellectual discipline was only slightly irritating.

Bob: Sorry, we got carried away. Just to complete the introductions, I’m Bob, and this is Sarah.

Roxana: That is enough time on trivialities. I will explain the error in what the woman called ‘Sarah’ said.

Sarah: Call me ‘Sarah’, not ‘the woman called “Sarah” ’, if you please.

Bob: ‘Sarah’ is shorter.

Sarah: Not only that. We’ve been introduced. It’s rude to describe me at arm’s length, as though we weren’t acquainted.

Roxana: If we must be on first name terms, so be it. Do not expect them to stop me from explaining your error. First, I will illustrate Aristotle’s observation about truth and falsity with an example so simple that even you should all be capable of understand­ing it. I will make an assertion.

Bob: Here goes.

Roxana: Do not interrupt.

Bob: I was always the one talking at the back of the class.

Zac: Don’t worry about Bob, Roxana. We’d all love to hear your assertion. Silence, please, everyone.

Roxana: Samarkand is in Uzbekistan.

Sarah: Is that it?

Roxana: That was the assertion.

Bob: So that’s where Samarkand is. I always wondered.

Roxana: Concentrate on the logic, not the geography. In making that assertion about Samarkand, I speak truly if, and only if, Samarkand is in Uzbekistan. I speak falsely if, and only if, Samarkand is not in Uzbekistan.

Zac: Is that all, Roxana?

Roxana: It is enough.

Bob: I think I see. Truth is telling it like it is. Falsity is tell­ing it like it isn’t. Is that what Aristotle meant?

Roxana: That paraphrase is acceptable for the present.

Tetralogue by Timothy Williamson is a philosophy book for the commuter age. In a tradition going back to Plato, Timothy Williamson uses a fictional conversation to explore questions about truth and falsity, knowledge and belief. Four people with radically different outlooks on the world meet on a train and start talking about what they believe. Their conversation varies from cool logical reasoning to heated personal confrontation. Each starts off convinced that he or she is right, but then doubts creep in. During February, we will be posting a series of extracts that cover the viewpoints of all four characters in Tetralogue. What follows is an extract exploring Zac’s perspective.

Zac wants everyone to be at peace with everyone else, whatever their differences. He tries to intervene and offer a solution to the conflicts that arise between the other characters, but often ends up getting dragged in himself.

Sarah: It’s pointless arguing with you. Nothing will shake your faith in witchcraft!

Bob: Will anything shake your faith in modern science?

Zac: Excuse me, folks, for butting in: sitting here, I couldn’t help overhearing your conversation. You both seem to be getting quite upset. Perhaps I can help. If I may say so, each of you is taking the superior attitude ‘I’m right and you’re wrong’ toward the other.

Sarah: But I am right and he is wrong.

Bob: No. I’m right and she’s wrong.

Zac: There, you see: deadlock. My guess is, it’s becom­ing obvious to both of you that neither of you can definitively prove the other wrong.

Sarah: Maybe not right here and now on this train, but just wait and see how science develops—people who try to put limits to what it can achieve usually end up with egg on their face.

Bob: Just you wait and see what it’s like to be the vic­tim of a spell. People who try to put limits to what witchcraft can do end up with much worse than egg on their face.

Zac: But isn’t each of you quite right, from your own point of view? What you—

Sarah: Sarah.

Zac: Pleased to meet you, Sarah. I’m Zac, by the way. What Sarah is saying makes perfect sense from the point of view of modern science. And what you—

Bob: Bob.

Zac: Pleased to meet you, Bob. What Bob is saying makes perfect sense from the point of view of traditional witchcraft. Modern science and traditional witch­craft are different points of view, but each of them is valid on its own terms. They are equally intelligible.

Sarah: They may be equally intelligible, but they aren’t equally true.

Zac: ‘True’: that’s a very dangerous word, Sarah. When you are enjoying the view of the lovely countryside through this window, do you insist that you are see­ing right, and people looking through the windows on the other side of the train are seeing wrong?

Sarah: Of course not, but it’s not a fair comparison.

Zac: Why not, Sarah?

Sarah: We see different things through the windows because we are looking in different directions. But modern science and traditional witchcraft ideas are looking at the same world and say incompatible things about it, for instance about what caused Bob’s wall to col­lapse. If one side is right, the other is wrong.

Zac: Sarah, it’s you who make them incompatible by insisting that someone must be right and some­one must be wrong. That sort of judgemental talk comes from the idea that we can adopt the point of view of a God, standing in judgement over every­one else. But we are all just human beings. We can’t make definitive judgements of right and wrong like that about each other.

Sarah: But aren’t you, Zac, saying that Bob and I were both wrong to assume there are right and wrong answers on modern science versus witchcraft, and that you are right to say there are no such right and wrong answers? In fact, aren’t you contradicting yourself?
