If perception is free of concepts, as Dignāga says, how do I ever see a cup as a cup?
I've been reading an introduction to Buddhist epistemology on the train, and I'm stuck on Dignāga's definition of perception (pratyakṣa) as "free from conceptual construction". As I understand it, the object of perception is the bare particular, and anything general, like "cup",…

My students used the surprise test paradox against me. Where exactly does their argument fail?
On Friday I told my class XI section that there would be a surprise test some day next week, Monday to Friday, and that they would not know the evening before which day it was. By the end of the period one…

What are the “objectives of the law” (maqāṣid) that people keep mentioning, and why do they matter?
In a discussion at our mosque youth group, one speaker kept saying that a ruling has to be understood "through the maqāṣid", the objectives or purposes of the sharia. Another person said this is exactly how people end up ignoring the texts.…

My cousin’s biopsy result already exists. Does it make sense to pray that it is benign?
My cousin had a biopsy on Friday. The results come on Wednesday. Whatever is in that tissue is already there; the lab will only tell us. Yet the whole family is praying that it will be benign, and so am I. A…

Midterm on Thursday: if a Pyrrhonist suspends all judgement, how does she get out of bed?
I'm taking a philosophy elective alongside my psychology courses, and Thursday's midterm covers Hellenistic philosophy. One question on the past papers keeps coming up: "Can the Pyrrhonian skeptic live their skepticism?" My notes say Pyrrhonists suspend judgement about everything, and that their…

In Aymara the past lies in front of us. Is that only a way of speaking, or a truer idea of time?
In Aymara, the word nayra means eye, and front, and also the past. The past is ahead of you, because you can see it. What is coming is qhipa, behind, at your back, because nobody can see it. My grandmother pointed forward…

Every cell in my body is replaced every seven years, so am I even the same person?
At Sunday lunch my uncle reminded me that I borrowed 20,000 shillings from him when I was fifteen. I said, as a joke, that every cell in my body has been replaced since then, so the boy who borrowed it is gone…

Is a promise to someone who has died still binding if no one living would know?
Before she died, my husband's grandmother made me promise that the recipe for our bakery's bread would stay in the family. It is not a secret of state. It is flour, water, salt, a little of something, and the way you fold…

What does dependent origination actually claim? My daughter asked and I had no answer
My daughter is fourteen. Last week, stuck in traffic near Borella, she asked me what paṭicca samuppāda means. I have heard the word at the temple my whole life. I said "it means everything is connected", and she said that sounds like…

Is a controlled experiment a new source of knowledge, or only perception with discipline?
I have been reading A. I. Sabra's translation of the first books of Ibn al-Haytham's Optics with two of my tutoring students, and it has raised a question I can't settle. The standard lists of sources of knowledge, whether European or Indian,…

Are possible worlds real, or just a bookkeeping device?
David Lewis, in On the Plurality of Worlds (1986), argued that other possible worlds are just as real as ours. "Actual" is indexical, like "here". Our world is actual only in the sense that we are in it. Almost nobody follows him…

I keep reading summaries of philosophers instead of the books. Is that so bad?
Confession: in the year since I burnt out and started reading philosophy, I've read maybe three actual books and hundreds of summaries, threads, videos and ‘ten ideas from Stoicism’ posts. I can tell you what Kant, Nietzsche and the Gita say in…

How can you talk about non-being without turning it into a something?
Every morning I practise taiji in the park and every evening I read a few lines of the Laozi with my grandson's dictionary. Chapter 40 says, roughly, that the things of the world are born from being, and being is born from…

What’s the difference between deduction, induction and abduction?
My students know "deduction" and "induction" from school, though they often mix them up. I recently read that Charles Sanders Peirce added a third type of reasoning, abduction. Could someone explain all three clearly, with examples, and why Peirce thought abduction mattered…

What’s the difference between a valid argument and a sound one?
In a debate thread here someone said an argument was "valid but not sound" and I realised, being completely new to logic, that I didn't understand the difference. To me both words just sounded like "good". Could someone explain simply, with examples…

If only the transformed can know, how could a mystic ever be shown to be wrong?
Since I campaign against superstition, let me say first that I'm not asking this to sneer. I read Sufi poetry with real pleasure, and I've learned from discussions here that the Sufi claim is subtler than "feelings beat reason". The claim, as…

Did non-Euclidean geometry sink Kant’s view of space?
I am a retired teacher in Freiburg, finally reading the Critique of Pure Reason properly, and I am stuck on the Transcendental Aesthetic. Kant says space is not a thing in itself and not a set of relations among things in themselves.…

Could the constants have been different? Spinoza says no; the Ashʿarites say God could change them tomorrow
I model oil reservoirs. Every model has parameters, and every morning I change some of them to see what would have happened. So the question "could the physical constants have been different?" feels very concrete to me, and I've found two answers…

Is “Islamic philosophy” a useful label?
Some colleagues prefer "Arabic philosophy". Others say "philosophy in the Islamic world". Each has problems. "Islamic philosophy" suggests that it's all religious, or that all of it was done by Muslims. But Christians like Yahya ibn 'Adi and Jews like Maimonides wrote…

Would games really be the only thing left worth doing in utopia?
Bernard Suits ends The Grasshopper with a strange and wonderful claim. Imagine a utopia where every instrumental need is met: machines do all the work, nobody needs to earn, build, heal or cook. What would people do? Suits's Grasshopper argues that they…

Is an economy more than the people in it?
Economics lives with a tension it never resolves, and I meet it at work every year. On one side, methodological individualism: social phenomena should be explained, ultimately, by individuals' choices and interactions. Prices, unemployment and recessions are patterns of individual behaviour. Most…

Bundle theory or bare particulars: which embarrassment would you rather live with?
I tutor logic and keep running into this in tutoring sessions, so I'd like to hear people argue it properly. Bundle theory: an object is nothing but a bundle of properties. There is no underlying thing that "has" the redness and the…

What did Ibn Sina mean by the “internal senses”?
In my history of psychology course, Ibn Sina was mentioned for his theory of "internal senses", and the lecturer said it was an early version of cognitive psychology. I'd love a clear explanation of what the internal senses were and how they…

What does “intersectionality” mean philosophically, beyond the slogan?
In journalism the word "intersectionality" is everywhere, and it's often used just to list identities. I know Kimberlé Crenshaw introduced the term in 1989, but I'd like to understand the original argument and what philosophical claim, if any, it makes.

Plantinga’s proper function: does warrant need a designer, or will evolution do?
This term a student asked me a question I could not answer cleanly, so I bring it here. Alvin Plantinga's account of warrant, in Warrant and Proper Function (1993), says roughly that a belief has warrant if it is produced by cognitive…

Can you be religious and a philosophical skeptic at the same time?
This semester I took a module on scepticism, Pyrrhonism, Descartes' demon and so on, and I found some of the arguments hard to answer. Now I'm wondering whether serious scepticism is compatible with religious faith, or whether every believer is just a…

What is longtermism, and what’s the main objection to it?
Everyone in tech talks about longtermism. I know it's connected to effective altruism and William MacAskill's What We Owe the Future (2022). But I've never seen a clear explanation of the core argument and the best objections. Can someone help?

Capabilities or the social model: which better tells a city what it owes disabled residents?
In a moot this term we had to argue about what a municipal corporation owes disabled residents under India's disability-rights legislation. I found myself reaching for two frameworks that don't fit together as neatly as our professors suggest. The social model tells…

How does Ibn Sina’s proof of the Necessary Existent avoid the infinite regress problem?
I understand the basic structure: things that exist are either necessary in themselves or possible (contingent) in themselves. Contingent things need a cause. So there must be a necessary being. But why can't there be an infinite chain of contingent beings, each…

Can a translation of a poem be as beautiful as the original?
