A verdict that was right by accident: did the court know he was guilty?
Many years ago, early in my time as a court correspondent, I watched a magistrate convict a young man of a burglary largely on the identification of one witness. The identification was confident, the defence was weak, and I was as satisfied…

Zhuangzi and Hui Shi on the bridge: an ancient argument about knowing what someone else knows
What does this part of the system know about what that part knows? I spent forty years on that question as a railway signalling engineer. I found the same question in the most famous conversation in Zhuangzi. Zhuangzi and Hui Shi are…

Epsilon-delta is two nested quantifiers, and that is why my students struggle
Every year I teach limits to senior secondary students in Delhi, and every year the same thing happens. They can compute limits perfectly well. Then I write the definition: For every ε > 0 there exists a δ > 0 such that…

If the past no longer exists, what exactly is my regret about?
I served twenty-two years in the army, the last part on the DMZ. There are a few decisions I regret, none of them dramatic, all of them still with me. Reading about the philosophy of time has given me a strange new…

Ibn Sina begins the Canon by defining medicine. What does that definition assume about health?
I recently reread the opening of Ibn Sina's Canon of Medicine for a reading group at the hospital, and I was struck by how much philosophy is packed into the first sentence. Paraphrasing: medicine is the knowledge of the states of the…

Usul al-fiqh and Dworkin’s integrity: two ways of saying law is more than its rules
I read Iqbal and Hart side by side, more or less as a hobby, and lately I have been adding Dworkin and al-Shafi'i to the pile. I want to test a comparison that I find tempting and suspect is partly false. Dworkin…

Thirty-one years of watching courts decide what is ‘reasonable’, and no degrees of truth in sight
Here is something I watched every week in the courts of Punjab. A large part of the work was applying words that have no sharp edges: "reasonable doubt", "sudden provocation", "sufficient cause", "unsound mind". Now I read that fuzzy logic was invented…

Why insight does not instantly change behaviour: an Abhidhamma account of knowing and not doing
I read the threads here about whether knowing what is right necessarily moves you, and I would like to add the account I have lived with in twelve years of practice. In the Pali discourses, the Buddha says that intention, cetanā, is…

Soul as the form of a living body: does Aristotle help me teach the Igbo idea of chi, or get in the way?
I teach religious studies at a Catholic secondary school in Enugu and run a philosophy club for the senior students. Every year we read Aristotle's De Anima, where the soul is defined as the first actuality of a natural body that potentially…

The five rulings, from obligatory to forbidden: why the middle categories are not just extra boxes
Standard deontic logic has three basic statuses: obligatory, forbidden, and permitted. Anything neither obligatory nor forbidden is simply permitted, and that's the end of it. Islamic jurisprudence has five rulings (al-aḥkām al-khamsa). An act is obligatory (wājib), recommended (mandūb), permissible (mubāḥ), disliked…

Al-Ma’arri gave up meat, milk and honey, and wrote a poem telling us why
Abu al-'Ala al-Ma'arri (973–1057) lost his sight to smallpox as a child and called himself the prisoner of two prisons, his blindness and his house in Ma'arrat al-Nu'man. I read him first for his fury. I stayed for his ethics. In his…

Keeping the losing opinion on the page: is disagreement inside a tradition as deep as disagreement between traditions?
In my Tuesday Talmud study group we recently read the story in tractate Eruvin about the houses of Hillel and Shammai, who argued for years until a heavenly voice declared that "these and these are the words of the living God", and…

What do I owe a source I don’t believe? Notes from a court reporter
I cover courts and human rights in Karachi. Every week someone tells me something I am not sure I believe: a family about a disappeared relative, an official about a raid, a lawyer about what his client said. I have to decide…

Seeing before naming: are Dignāga and Merleau-Ponty saying the same thing about perception?
Two accounts of perception seem to me to speak to the moment just before a word arrives, which is where a translator spends her days. Dignāga, the Buddhist epistemologist of the late fifth and early sixth centuries, defines perception as cognition free…

If the comparison table had a Yoruba row: mọ̀, gbàgbọ́ and the gap between seeing and hearing
Comparative tables of how traditions answer "how do we know anything?" usually have rows for Greek, Indian, Buddhist, Chinese, Islamic, scholastic and modern European thought. My doctorate is on Yoruba epistemic vocabulary, so I want to sketch the row that is usually…

Even if the proof works, whose God has it reached? The gap from “first cause” to God
I teach adults in Jerusalem who often arrive believing that philosophy and religion are enemies. One thing I show them early is that even a successful argument for a first cause or a necessary being leaves a large question open: why call…

Heraclitus, Vasubandhu, Zhuangzi, Mulla Sadra: four routes to process, or four destinations?
It is often said that four thinkers, with no documented transmission between them, all arrived at a process view of reality: Heraclitus in Greece, Vasubandhu in India, Zhuangzi in China, and much later Mulla Sadra in Safavid Iran. The convergence is real.…

Does every culture have a word for ‘art’? Technē, kalā and the Japanese ‘ways’
I spend a lot of time warning people about false friends in comparison. One of the biggest sits under the whole debate about defining art. Greek technē is usually translated "art", but it means skilled making of any kind: medicine, shoemaking, navigation,…

Al-Fārābī’s virtuous city looks different on a bad day in a bookshop

Nāgasena’s condition for talking with a king: argue as scholars do, not as kings do
Early in the Milindapañha, the Questions of King Milinda, the king asks the monk Nāgasena to discuss with him. Nāgasena answers with a condition. He will talk if the king will talk as scholars do, not as kings do. What's the difference?…

Kumārila said a cognition is valid until shown otherwise. Is that internalism or externalism?
The Mīmāṃsā school I follow holds a doctrine called svataḥ prāmāṇya, intrinsic validity. I have been reading the internalism and externalism debate in English, and I would like to know whether this doctrine belongs on one side, or whether the map does…

“A hundred scriptures cannot make fire cold”: Śaṅkara’s rule for when scripture and perception collide
Discussions here of reason and revelation usually draw on Ibn Rushd and Maimonides. They deserve it. But the Advaita tradition worked out its own conflict rule, and I think it belongs in the same conversation. For Śaṅkara, scripture (śruti) is a means…

What Ibn al-Haytham actually did, and why “father of the scientific method” overstates it
Every few weeks someone sends me a graphic declaring that Ibn al-Haytham invented the scientific method centuries before Bacon. I understand the impulse. The standard Western story did put the origins of experimental practice far too late. But the slogan replaces one…

My brother’s conversion: can an experience be real and its interpretation wrong?

Navya-Nyāya’s language of limitors, and what it was built to do
Every few months someone tells me that Navya-Nyāya was "Indian predicate logic". I'd like to test that claim with people who know Frege better than I do. The school is usually dated from Gaṅgeśa's Tattvacintāmaṇi in the fourteenth century. What Gaṅgeśa and…

Trustee or plain citizen? Nasr’s khalifa and Leopold’s land community
A Persian garden is a strange object: entirely human-made, geometric, irrigated by channels that took enormous labour, and yet everyone who walks in feels that it is a picture of something given, not imposed. I've been reading two environmental thinkers who seem…

Al-Shaybani’s siyar and the scholastics reached civilian immunity separately
In retirement I have been reading Majid Khadduri's 1966 translation of al-Shaybani's siyar, published as The Islamic Law of Nations. Al-Shaybani (749–805) was a student of Abu Hanifa, and his work on the siyar is one of the earliest systematic treatments of…

Devadatta is fat but never eats by day: is Mīmāṃsā “postulation” just inference to the best explanation?

When rhetoric and poetry were counted as logic: the Arabic Organon and al-Jāḥiẓ on eloquence

Nāgārjuna says he has no thesis. Is “I have no thesis” itself a thesis?
There is a question I keep returning to, the oldest one in the long argument between Advaitins and Mādhyamikas. In the Vigrahavyāvartanī, answering a critic who says his claim that all things are empty refutes itself, Nāgārjuna says (I paraphrase): if I…
