Could a culture reason by different logical rules, or is that a colonial myth?
Every year a student in my lycée class asks me some version of this: "Is logic universal, or is it just how Europeans think?" The history makes the question sharp. In the early twentieth century, Lucien Lévy-Bruhl described so-called primitive peoples as…

Why did argument appear in Greece, India, China and Israel in the same few centuries?
When someone shows me a pattern I want a mechanism. Granting for the moment that something similar happened in several regions between roughly 800 and 200 BCE, with no documented transmission between them, the explanations I've seen are: Material surplus. Iron-age agriculture…

What are the Nyāya hetvābhāsas, and do they line up with the Western list of fallacies?
I've been reading about Nyāya logic on weekends. I keep meeting the word hetvābhāsa, usually translated "fallacy" or "pseudo-reason", and a list of five kinds. My questions, as a non-specialist: What are the five, in plain terms, with an example of each…

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.…

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…

Is Yājñavalkya’s unseen seer an answer to the problem of personal identity?
I study Sanskrit and Indian philosophy in Pune, and something about how Indian theories of self get slotted into Western debates bothers me. In the Bṛhadāraṇyaka Upaniṣad, Yājñavalkya says you cannot see the seer of seeing or think the thinker of thinking,…

Can trained meditative introspection count as evidence? Abhidhamma and William James
For years my study has been the Abhidhamma, the systematic part of our canon that analyses experience into momentary mental events and their factors. In the classical Theravada scheme there are fifty-two mental factors (cetasika), seven of which are said to accompany…

What is apoha, and does defining by exclusion help with the frog-and-fly problem?
I teach philosophy at an upper-secondary school in Lund, and my hobby is reading Sanskrit philosophers in translation and noticing where they reached our problems first. I would like a clear explanation of one idea I only half understand. Dignāga, the fifth-…

Why did the Vaiśeṣikas count direction as a substance?
I teach physics and spend weekends exposing miracle tricks for a rationalist association, so I like the Indian schools that tried to describe the world piece by piece. The Vaiśeṣika list of nine substances is a favourite of mine: earth, water, fire,…

If syllogistic logic couldn’t handle relations, why did it last two thousand years?
Working inside predicate logic every day, I'm often reminded how much it can do that the syllogism can't. The textbook example (usually credited to De Morgan) is: all horses are animals, therefore every head of a horse is the head of an…
