If the Big Bang marks the edge of a theory rather than a beginning, what is left of the kalām’s physics?
I studied physics, and I get asked about this a lot by friends who have watched debates online. Here is what I think the physics actually says. The hot Big Bang phase of the observable universe has a finite age, about 13.8…

Mozi was a consequentialist two thousand years before Bentham, and lost the argument the same way
I read the later Mohist canons closely, so I live with this comparison. Here's the case. Mozi, writing in the fifth century BCE, argued that the test of any doctrine or policy is whether it promotes benefit and removes harm for the…

When Aristotle calls humans political animals, does he mean we need a government?
At least once a debate tournament some student cites Aristotle: "man is a political animal." It always gets used to mean that people need government, or that humans are naturally into politics, like campaigning and voting. I have a nagging feeling that's…

Algorithmic hiring tools are inherently unjust
I don't say this lightly. Algorithms trained on past hiring decisions learn past discrimination. The best-known case: Amazon built an experimental recruiting tool that, as Reuters reported in 2018, learned to penalise CVs containing the word "women's" (as in "women's chess club…

Why is “begging the question” not the same as “raising the question”?
My students, and frankly most newspapers, use "this begs the question" to mean "this raises the question". A colleague told me that's wrong and the phrase refers to a fallacy. Could someone explain the fallacy properly, with a clear example, and where…

Refusing to aggregate is contractualism’s best feature, not its embarrassing bug
Scanlon's transmitter room case: a technician is trapped under equipment in a TV station, receiving painful electric shocks. Freeing him means interrupting the broadcast of a big football match for fifteen minutes, and millions of people are watching. Add up the millions…

A deliberate foul that accepts its penalty is still a move within the game
Here is a thesis from someone who builds rule systems for a living: a tactical foul, committed openly and paid for with the stated penalty, is part of playing the game, not a break from it. The strict formalist reading of Suits…

There is no self: the Buddhist and Humean bundle views are basically right
Hume, in the Treatise (Book 1, Part 4, Section 6), says that when he looks within he never catches "himself", only some particular perception: heat, cold, love, pain. The self is a bundle of perceptions in constant flux. The Buddhist doctrine of…

What does Langdon Winner mean when he says artifacts have politics?
Anyone who builds puzzle games already believes that rules built into a world shape what people do in it. If I put a locked door at the end of a corridor, players will spend twenty minutes looking for a key, and none…

Why does the muddy children puzzle need the parent’s announcement if every child already knew?
A colleague at the studio showed me the "muddy children" puzzle. I love it and I don't understand it. Three children, each with mud on their forehead. Each can see the others but not themselves. A parent says: "At least one of…

Can someone explain what the Nyāya logicians meant by vyāpti (pervasion)?
My training is entirely in Western formal logic, and I've started reading Matilal's The Character of Logic in India. I understand the standard example: there is fire on the hill because there is smoke, and wherever there is smoke there is fire,…

Essence and existence: why Ibn Sina’s distinction mattered to Aquinas
In the metaphysics of the Shifa', Ibn Sina distinguishes what a thing is, its essence or quiddity (mahiyya), from the fact that it is, its existence (wujud). You can understand what a triangle or a phoenix is without knowing whether any exists.…

I have grown cocoa for thirty years and never seen chocolate made. How do I know that is where it goes?
Last week my son sent me an article that said most of what any of us knows, we know only because somebody told us. I laughed, then I thought about it while I was splitting pods. I have grown cocoa for thirty…

A universal basic income would make people freer, not lazier
Philippe Van Parijs, in Real Freedom for All (1995), argues that a just society should maximise everyone's real freedom to do whatever they might want to do, and that an unconditional basic income is the best way to do it. Republicans in…

I butcher pigs at work and my dog sleeps on my bed. Is that inconsistent?
I'm a chef from Goa, which means pork is close to the centre of the food I grew up with: sorpotel, vindaloo, chouriço. In my kitchen in Dubai I break down whole pigs when we can get them. At home I have…

Reading group: Huizinga’s Homo Ludens, starting with ‘Nature and Significance of Play’
Huizinga has sat unread on my shelf for too long, and I'd like company to finally read him. Homo Ludens (1938) argues that play is older than culture, since animals play without anyone teaching them, and that law, war, poetry, philosophy and…

Reading group: Yājñavalkya, Maitreyī and Gārgī in the Bṛhadāraṇyaka Upaniṣad
Reading Śaiva Siddhānta on my own, I want to go back behind the schools to the text they all argue over. The Bṛhadāraṇyaka is the oldest and, for me, the most alive of the Upaniṣads, mostly because of Yājñavalkya and the two…

Can someone explain Ramanuja’s Vishishtadvaita fairly, from an Advaitin’s point of view?
I confess I have never given Rāmānuja the attention he deserves. My Vaishnava friends tell me I misrepresent him whenever I speak about him. So I ask, in good faith: what exactly is Vishishtadvaita, "qualified non-dualism"? How does it differ from Advaita…

“That’s not what I meant”: a comic on jokes, apologies and who owns the meaning
Friday night in a club in Salford, I did a bit about my mum's driving. A bloke near the front decided it was about him, because he'd heckled about my accent earlier, and he came up afterwards furious. My first instinct was…

Why does tax feel like theft to some of my clients and not to others?
Two of my tax clients run nearly identical businesses: same size, same bracket, similar families. Every April one of them tells me, only half joking, that the government is robbing him. The other says, with no irony, that tax is the membership…

Nagarjuna’s tetralemma is not a rejection of logic
The catuṣkoṭi, or tetralemma, considers four options for any proposition: it is, it is not, both, neither. In the Mūlamadhyamakakārikā, Nāgārjuna often rejects all four. For example, the Buddha after death neither exists, nor doesn't exist, nor both, nor neither. Some readers…

Han Feizi’s case for clear law, read in Lahore

I do tax returns. When a colleague gets a different total, should I move halfway?

Can Kant’s rule against treating others merely as means be stretched to cover animals?

Are Kant’s formulations of the categorical imperative really equivalent?

Is a mayonnaise emergent? A cook asks about weak and strong emergence

Monks take the great vows, I take the small ones: is a graded ethic a cop-out?
Jain ethics has five vows: non-harm, truthfulness, not stealing, sexual restraint and non-possession. Monks and nuns take them as the great vows, absolutely. Laypeople like me take them as the small vows, in a limited form suited to a householder's life. So…
