Gödel’s incompleteness theorems are constantly misused in philosophical arguments
A public service post, since I see this weekly. What the first theorem says, roughly: any consistent, effectively axiomatised formal system that contains enough arithmetic has true sentences in its language that it can't prove. The second says such a system can't…

Persian gardens, proportion, and Plato’s Timaeus
The classical Persian garden, the chahar bagh, is divided into four parts by water channels meeting at a centre. Visit the Fin Garden in Kashan or Bagh-e Eram in Shiraz and you feel the order before you understand it. In the Timaeus,…

“Because that’s how it works”: when is that an explanation and when is it a refusal?
New cooks ask why a lot. Why rest the meat? Why salt the pasta water and not the sauce at the start? Why does this sauce split if you rush it? When I was an apprentice in Goa my chef answered almost…

Found the Master Argument in Epictetus, between two bus stops
Another find from my recordings. Last week it was Epictetus, Discourses Book 2, and in the middle of a chapter he mentions an argument by Diodorus Cronus that clever people used to show off with. I had to pull my attention back…

Kant and the murderer at the door: can the essay be rescued?
In 1797 Kant published "On a Supposed Right to Lie from Philanthropy", replying to Benjamin Constant. He maintains that you may not lie even to a murderer who asks where your friend is hiding. When I taught this, nearly every student found…

Is Aquinas’s First Way really about a first moment in time?
Most of my friends assume Aquinas's arguments for God (Summa Theologiae I, q.2, a.3) are about the beginning of the universe: everything has a cause, so go back far enough and you find God at the start. But my lecturer says that's…

Al-Ghazali’s Deliverance from Error as a story about information overload
I've been reading al-Ghazali's Deliverance from Error (al-Munqidh min al-Dalal), written late in his life. He describes his search for certain knowledge among four groups: the theologians, the Batinis (who relied on an infallible teacher), the philosophers, and the Sufis. Before that,…

My cooks are free to leave, in theory. What republican liberty sees in a kitchen
I came from Goa to cook in Dubai fifteen years ago, and I'm proud of how we treat people in my kitchen now. Nobody is shouted at. Overtime is paid. When someone's mother is ill, we find a way to send him…

The hard problem from a psychology student’s point of view
In 1995 David Chalmers distinguished the "easy problems" of consciousness (explaining discrimination, attention, reportability, the control of behaviour) from the "hard problem": explaining why any of this is accompanied by subjective experience at all. In my psychology courses we study the easy…

Is the Allegory of the Cave a theory of education first and a metaphysics second?
The cave in Republic VII is usually read as a story about two worlds: shadows down here, Forms up there. That's not wrong, but I've come to think it isn't the emphasis Plato gives it. Socrates introduces the image as a picture…

Why a joke dies in Leeds and kills in Salford: notes from a stand-up
I've started reading philosophy of humour because I want to know why the exact same bit, same words, same timing, can get silence in one room and a roar in another twenty miles away. The theory that has helped me most is…

Ahimsa in Jainism: how far can non-harm be taken?
I grew up next door to a Jain family in Hyderabad. The grandmother wouldn't eat after sunset (to avoid harming insects attracted to light), and they avoided root vegetables, since pulling them up kills the whole plant and the many small organisms…

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…

“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've been reading Han Feizi with more sympathy than I expected. His central insight about law is one I see confirmed every week in our courts. Where the rules are unclear, or applied differently depending on who you are, the powerful win…

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

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…

Testimony as an information channel: Nyāya’s śabda next to Dretske
I've been reading Dretske for a seminar alongside the Nyāya Sūtra, and I think they illuminate each other on testimony in a way neither does alone. Nyāya counts four means of knowing (pramāṇa): perception, inference, comparison, and śabda, word or testimony. The…

Does ‘atom’ in my physics class refer to what Dalton meant by it?
Last week one of the students I tutor for school-leaving exams asked, half joking, whether Dalton was "wrong about atoms or right about something else". It is a better question than it sounds. Dalton's atoms were indivisible. A few generations later Thomson…

Iqbal’s khudi and Nietzsche’s Übermensch: influence or polemic?
Iqbal's Persian poem Asrar-i-Khudi (1915), translated by R. A. Nicholson as The Secrets of the Self (1920), makes the self, khudi, the centre of his philosophy. The self must be strengthened, disciplined and creatively asserted, not dissolved in mystical annihilation. Western readers…

The kalam cosmological argument: what the mutakallimun actually argued

Does quantum indeterminacy help free will at all?
People sometimes argue that because quantum mechanics is indeterministic, there's room for free will. Having studied physics, I'm sceptical. First, randomness isn't freedom. If my decision depends on a random quantum event, it isn't more mine than if it were determined. Second,…

Camus and the Buddhists: two ways of refusing the question of life’s meaning

Langar, the Shabbat table and Confucius’s sauce: what does eating together do?

Mulla Sadra’s substantial motion: is everything changing at the level of substance?
For Aristotle, motion happens in a few categories only: quantity (growth), quality (a leaf turning red), and place. Substance doesn't move; it's the stable subject of change. When one substance becomes another, that's generation and corruption, not motion. Mulla Sadra disagreed. His…

Ibn Khaldun’s asabiyya and the rise and fall of states
The central concept of the Muqaddimah is asabiyya, usually translated "group feeling" or "solidarity". Ibn Khaldun argues that groups living hard lives on the margins of civilisation, often nomadic or tribal, develop strong solidarity. That solidarity lets them conquer settled states. Once…

Night shifts and Epictetus: the dichotomy of control in a care home
