Does Spinoza solve the mind–body problem or just rename it?
I came to this site for philosophy of mind and stayed for Spinoza, so I owe the question. Spinoza's move, as I understand it: there is one substance, with infinitely many attributes, of which we know two, thought and extension. A mind…

A source that is not one of the things it produces: Anaximander’s apeiron and Plotinus’s One
In my library we keep a small display on the Alexandrian Neoplatonists, and I have been rereading Plotinus between cataloguing jobs. What strikes me is a move that appears, in different forms, at both ends of Greek philosophy. Anaximander, very early, said…

Al-Fārābī’s virtuous city looks different on a bad day in a bookshop
On quiet afternoons in the shop I read al-Farabi, who lived and taught in this city a thousand years before me. In The Opinions of the People of the Virtuous City he compares the excellent city to a healthy body, in which…

Mulla Sadra’s substantial motion: what if things change in their very substance?
I am an architect in Shiraz, and Mulla Sadra, who was born here, keeps pulling me back to questions about being. This one has been on my mind since I started reading about persistence. In Aristotle's framework, which Ibn Sina refined, a…

The Gita’s svadharma cannot be cleanly separated from varṇa, and readers should face Ambedkar’s reading
I want to raise this respectfully, because the Bhagavad Gita is sacred to many people I love, including my own grandmother. But I think a popular modern reading of it avoids a hard question. The verse everyone quotes is that it is…

“I know what I saw”: what is a witness actually claiming?
I cover courts and human rights in Karachi. The sentence I hear most often in witness boxes is "I know what I saw." It's said with total conviction, often by people who are mistaken. Psychologists have shown how fragile this is. Elizabeth…

Scholastic reasoning was rigorous, but it was rigour inside a fence
I'm an atheist, and I don't share the old Enlightenment sneer at the scholastics. The method was superb: state the objections, distinguish the senses of terms, answer point by point. Modern philosophy papers are built on it. But I want to argue…

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…

Anscombe was right: no emergency makes it permissible to target civilians deliberately
Here is the hardest case for the principle of discrimination. Suppose deliberately attacking a civilian population would end a war years early and save more lives than it costs, including more civilian lives. The arithmetic points one way. Elizabeth Anscombe's answer was…

Hui Shi’s Ten Theses: paradoxes for their own sake, or a theory of space?
I spend most of my reading time on the Later Mohist canons, and I keep being drawn sideways to Hui Shi, Zhuangzi's friend and sparring partner. Almost nothing of his own survives. What we have is a list of ten theses preserved…

How does Islamic legal reasoning decide on a financial product that no text mentions?
Our product team at the bank is looking at a "buy now, pay later" service. Inevitably someone asked whether it's halal. Someone else said, a bit dismissively, that the Qur'an and hadith obviously don't mention smartphone instalment apps, so either the scholars…

What are Udayana’s arguments for God, and whom was he arguing against?
I am an atheist, and I am tired of Western debates about God being treated as the only debates. India had a long, sophisticated argument about a creator, and I know far less about the theist side of it than I should.…

Is “depression” one condition or several? A reader’s doubts
One question has followed me through years of my own analysis and of reading psychiatry: when two people receive the same diagnosis of major depression, do they have the same thing? Consider how the diagnosis works. A person needs five of nine…

Is a brilliantly made propaganda film a great film, or only a skilful one?
At a workshop for journalists on propaganda, we watched long stretches of Leni Riefenstahl's Triumph of the Will (1935), her film of the 1934 Nazi party rally at Nuremberg. Afterwards the room split badly. Some said: it is a great film made…

Frege and Husserl started on the same side. What was the psychologism dispute about?
I've been reading about the split between analytic and continental philosophy because my colleagues treat it as two tribes. What surprised me is that both traditions are said to trace back, around 1900, to two men who agreed about something: Frege and…

Reading group: Vasubandhu’s Twenty Verses, and whether ‘mind-only’ means idealism
Vasubandhu's Twenty Verses (Viṃśatikā), with his own short commentary, is the most compact argument for the Yogācāra claim that there is "only consciousness" (vijñaptimātra). It is also the text that most invites the question of whether Yogācāra is a form of idealism,…

Reading group: Frege’s Foundations of Arithmetic (1884), five weeks with Austin’s translation
Frege's Die Grundlagen der Arithmetik (1884) is short, sharp and still the best place to see why someone would think numbers are objects. J. L. Austin's translation (1950) has German and English on facing pages, which helps if anyone reads German. I…

Reading group: Kit Fine, ‘Vagueness, Truth and Logic’ (1975)
Vagueness is my obsession, and I've realised that many people know supervaluationism only from summaries. The original is better than the summaries. So: a slow read of Kit Fine's "Vagueness, Truth and Logic", first published in Synthese in 1975 and reprinted in…

Locke was right that the mind starts without ideas, and the argument from the newborn’s hunger fails
I'm biased towards Locke, I admit. But I came across an argument for innate knowledge from the Nyāya tradition that I had never seen, and I want to test my bias against it. Locke's case in Book I of the Essay is…

The self-defeat charge against the Cārvākas attacks a position they probably did not hold
I have a soft spot for the Cārvākas, India's materialists, who accepted perception as the only independent means of knowledge (pramāṇa) and rejected rebirth, the soul and the authority of scripture. Every rival school gave them the same knock-down reply: you reject…

“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…

Why did the rabbis write down the opinions they voted against?
I run a Talmud study group on Tuesday nights, and every year someone new asks the same thing: why does the text keep the losing side? When a law is decided, why preserve, often at length, the arguments of the sages who…

My brother’s conversion: can an experience be real and its interpretation wrong?
My younger brother is an engineer, a careful and slightly dry man, raised like me without religion. Last spring he spent a week at a Benedictine abbey, mostly because a colleague recommended the silence. He came back saying that during the night…

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…

What exactly was new about al-Khwarizmi’s algebra?
The word "algorithm" comes from the Latin form of al-Khwārizmī's name. “Algebra” comes from the al-jabr in the title of his book. So he is everywhere in my working vocabulary. But when I read about him, I get two stories. One says…

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…

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…

The Abhidharma was the most thorough reductionism ever attempted. Was it right?
I taught chemistry for years, and when I first studied the Abhidhamma I recognised something familiar: a periodic table of experience. The Abhidharma traditions analyse everything a person is into ultimate constituents, dhammas: momentary events of consciousness, mental factors, material qualities. In…

Is Yājñavalkya’s unseen seer an answer to the problem of personal identity?

What is Carnap’s distinction between internal and external questions, in plain terms?
