Reading group: Prior Analytics I.1–7, slowly, with a Nyāya inference on the table
Everyone says Aristotle invented formal logic, and I realise I have never read the Prior Analytics closely in company. So here is a proposal: the first seven chapters of Book I, over five weeks, which is where the whole assertoric system is…

Prophet and philosopher in al-Fārābī: one truth in two languages, or a ranking of believers?
I teach history in Fes, and al-Fārābī is the author I give my older students when they tell me philosophy and religion must be enemies. But I've started to wonder whether his reconciliation is as friendly as it looks. As I understand…

For ordinary speech, Aristotle was right: “All S are P” presupposes there are some S
Modern logic reads "All S are P" as "for anything, if it is S, it is P". If nothing is S, the statement comes out true automatically. So "All the unicorns in my garden are pink" is true, and so is "All…

Global scepticism refutes itself, and the famous escape routes do not work
The objection is old and short. If nothing can be known, then that nothing can be known cannot be known either. Global scepticism saws off the branch it sits on. Two escapes are usually offered, and I want to argue that neither…

Reading group: Miskawayh’s Refinement of Character, and Tusi’s Persian reworking of it
I'd like to read Miskawayh's Tahdhib al-Akhlaq together over the next couple of months. It is one of the most systematic works of philosophical ethics in Arabic, and it is a good place to watch Greek ethics being made at home in…

Unrestricted composition is the only principled answer to when parts make a whole
Thesis: any things whatever compose something. Here is why I think universalism is the only principled position. Restriction generates vagueness. If only some collections compose, there will be a sequence of cases, removing one particle at a time, in which composition goes…

If syllogistic logic couldn’t handle relations, why did it last two thousand years?
Working inside predicate logic every day, I'm often reminded how much it can do that the syllogism can't. The textbook example (usually credited to De Morgan) is: all horses are animals, therefore every head of a horse is the head of an…

Traditions that disagree about the self agree about how to live, so ethics can do without metaphysics
There is one comparison that always woke my students up. Put the great traditions side by side on what a person is, and they disagree completely: an immortal soul, an eternal self identical with the absolute, no abiding self at all, a…

The lazy argument fails against tawakkul just as it failed against the Stoics
Every so often someone at work tells me not to bother with a contingency plan because "what is written is written". I want to argue that this is a philosophical mistake, and an old one. Cicero's On Fate reports what the ancients…

Epictetus was a slave and I drive the 413. What counts as ‘up to us’ at work?
I drive the 413 across Ankara. Eight hours, two breaks, roughly three hundred passengers a day. I listen to philosophy lectures between stops, and Epictetus is the one I keep coming back to. The Handbook opens by dividing things into what is…

Aristotle’s account of friendship is still the best one we have
Books VIII and IX of the Nicomachean Ethics distinguish three kinds of friendship: for utility, for pleasure, and for character. Only the third is complete. In it you wish your friend well for their own sake, and the friend becomes something like…

I know within ten seconds whether a room will laugh, but I can’t say how. Does that count as knowing?
After a few hundred gigs you develop a sense for a room. I walk on, say two lines, and I know whether tonight is going to work. I'm right far more often than I'm wrong. Promoters have started asking me before they…

What exactly is Aristotle’s “function argument” in Nicomachean Ethics I.7?
This argument is easy to fumble when you explain it. My usual summary goes roughly like this: the good of anything that has a function lies in performing that function well human beings have a function it isn't nutrition and growth (plants…

The actual infinite is a useful fiction, not something real
Aristotle, in Physics III, allowed only the potential infinite: you can always count one more, but there's never a completed infinite totality. For two thousand years, most mathematicians agreed. Then Cantor, in the late nineteenth century, treated infinite sets as completed objects…

If consent of the governed is the newcomer, what did legitimacy rest on before it?
My students are learning about government this term. I showed them a comparative table of answers to the question "how should we be governed?" across many traditions: Greek, Chinese, Indian, Islamic, European. The thing that surprised them most was that only the…

I know the spider is harmless and I’m still terrified. Is my fear wrong, or just irrational?
I am very afraid of spiders. Last week one sat on my monitor for an hour. I knew it was a harmless house spider. I could have recited the facts about its venom. I still couldn't touch the keyboard. A friend who…

Reading group: Epictetus, Discourses II.19, where the Master Argument meets a bus driver
Epictetus, as people here know by now, is my favourite. Last month a lecture mentioned that the only clear report we have of the "Master Argument" of Diodorus Cronus is at the start of one chapter of his Discourses (the lectures his…

Epictetus says some things are up to us. What did that depend on for him?
Epictetus is still my favourite. The Handbook begins by saying some things are up to us and some are not: our opinions, desires and aversions are up to us; our body, property, reputation and office are not. In traffic this is very…

Is the flame on my burner a thing, or something that keeps happening?
I run a kitchen in Dubai, twenty-two cooks, nine countries, and on a slow afternoon I was staring at a gas flame. It keeps the same shape and colour for hours, but nothing in it stays: the gas comes in, burns, and…

Reading group: Plato’s Phaedo, weeks 1–3
I'd like to read the Phaedo slowly with anyone who is interested. It is the dialogue I return to most, and it reads differently every decade. Proposed plan: Week 1: the frame story and Socrates' claim that philosophers spend their lives practising…

A philosopher says there are no tables, only particles arranged tablewise. I make tables
A customer's son is studying philosophy in Rabat. While I was fitting their cedar ceiling he told me about a book called Material Beings by Peter van Inwagen. As far as I understood him, van Inwagen thinks that when many small things…

Can I keep Stoic advice and leave Stoic determinism behind?
The first line of Epictetus's Handbook changed how I work: some things are up to us and some are not, and suffering comes from confusing the two. But I've just learned that Stoic ethics isn't separable from Stoic physics in the way…

I banned fallacy names from my debate team for a month. Here’s what happened
My high-school debaters can name about thirty fallacies, mostly in Latin. They use them the way some people use swear words: as a way of ending an exchange rather than continuing it. "That's ad hominem." "That's a slippery slope." Judges nod. Nobody…

What was Hasdai Crescas’s case that an actual infinite is possible?

I make cedar doors. Am I an artist, a craftsman, or is that the wrong question?
Tourists photograph my work and call it art. Gallery people, when they come, call it craft, and they say it a little differently. I read recently that this division is young. Before the eighteenth century in Europe, making was one category judged…

Cārvāka and Epicurus, two ancient materialists at a deathbed
A question from the bedside. Epicurus helped me think about death without flinching: in the Letter to Menoeceus he says death is nothing to us, because where death is, we are not, and where we are, death is not. I've never repeated…

Orí and the Stoic cylinder: does a destiny you chose make you more free or less?
In Yoruba thought, before birth each person chooses an orí, literally a "head", meaning the inner self that carries one's destiny. One of the words for destiny, àkúnlẹ̀yàn, means something like "that which was chosen kneeling". You chose it, but you cannot…

Relativism about truth refutes itself, but relativism about morality does not, at least not so easily
There is a passage in Plato's Theaetetus where Socrates turns Protagoras's own doctrine against him. Protagoras says man is the measure of all things: what seems true to each person is true for that person. Socrates points out that most people believe…

Possibility lives in the powers of real things, not in other worlds

The statue-and-clay puzzle is a verbal dispute, and metaphysicians should admit it
