What exists, and what is it to be? Time, causes, freedom and necessity.

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…

The lazy argument fails against tawakkul just as it failed against the Stoics
Every so often someone at work tells me not to bother with a contingency plan because "what is written is written". I want to argue that this is a philosophical mistake, and an old one. Cicero's On Fate reports what the ancients…

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…

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…

Karma as moral causation: does the theory hold together?
The doctrine of karma says that actions have consequences for the agent that go beyond their visible effects, ripening in this life or future lives. It is shared, in different forms, by Hindu, Buddhist and Jain traditions. As an engineer I want…

Dōgen’s “being-time”: is time something things have, or something they are?
Dōgen (1200–1253), founder of the Sōtō Zen school in Japan, wrote a short and very strange essay in 1240 called "Uji", usually translated "Being-Time", which became part of his Shōbōgenzō. Its central claim is that time is not a container things exist…

Did Hume ever read al-Ghazali?
Last month I read al-Ghazālī's account of his crisis of doubt, and then went looking for more. I found the part of The Incoherence of the Philosophers about fire and cotton: we see the cotton burn when it touches the fire, but…

Does a deterministic program “choose”?
A chess engine searches millions of positions, scores them and plays the best move. We naturally say it "chose" the knight move. Yet it's fully deterministic: same position, same settings, same move every time. Spinoza thought our sense of free will comes…

Łukasiewicz, the sea battle, and why three-valued logic was born in Lwów
In De Interpretatione 9 Aristotle considers the sentence "there will be a sea battle tomorrow". If it is already true today, isn't the battle already necessary? And if so, isn't deliberation pointless? Around 1920 Jan Łukasiewicz, working in the Lwów–Warsaw school founded…

Emptiness is not nothingness: common misreadings of śūnyatā
I keep seeing "emptiness" in Buddhist philosophy explained as "nothing exists" or "everything is an illusion". That's exactly the view Nāgārjuna rejects as nihilism. For Madhyamaka, things are empty of intrinsic nature (svabhāva). They exist, but only dependently: on causes and conditions,…

What exactly is kasb (acquisition), and is it just compatibilism with God in it?
I have been reading about free will because it is the question that will not leave me alone. In Indonesia the answer I grew up with is that God creates everything, including my actions, but I am still responsible for them. When…

Reading group: Epictetus, Discourses II.19, where the Master Argument meets a bus driver
Epictetus, as people here know by now, is my favourite. Last month a lecture mentioned that the only clear report we have of the "Master Argument" of Diodorus Cronus is at the start of one chapter of his Discourses (the lectures his…

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…

Is ‘why is there something rather than nothing?’ a real question or just a very good bit?
I do stand-up, mostly in northern clubs, and I've got a bit about "why is there something rather than nothing". The punchline is that the universe exists because somebody forgot to cancel the booking. It does all right. Afterwards a bloke in…

My daughter asked whether a square circle could exist on another planet. How do I answer?
My nine-year-old has decided that "anything could be true somewhere in space". Last week it was square circles, this week it is a planet where two and two make five. I said no, and she asked why a planet with no gravity…

What is the “block universe”, and does relativity force it on us?
In physics classes we learned special relativity, including the relativity of simultaneity: observers in relative motion disagree about which distant events are simultaneous. Some philosophers argue this means the past, present and future are all equally real, the "block universe". Is that…

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…

Reading group: Nagarjuna, Mulamadhyamakakarika chapter 1 (on conditions)
The Mūlamadhyamakakārikā opens with an examination of causal conditions (pratyaya). The first verse says that nothing arises from itself, from something else, from both, or without a cause. The chapter then examines the four types of condition recognised by the Abhidharma schools:…

Al-Ghazali was right: causal necessity cannot be demonstrated
In the Seventeenth Discussion of The Incoherence of the Philosophers, al-Ghazali argues that the connection between what is customarily believed to be a cause and its effect is not necessary. When cotton touches fire and burns, observation shows only that the burning…

Compatibilism answers a question nobody was asking
I have now heard about four lectures defending compatibilism, and every time I feel the same thing: it changes the subject. Hume says liberty is just a power of acting or not acting according to the determinations of the will. Fine. When…

What does “primacy of existence” (asalat al-wujud) mean in plain terms?
I've read that Mulla Sadra's central doctrine is the primacy or "fundamentality" of existence over essence. I've also read that this is the opposite of a view held by Suhrawardi, or Mir Damad, or both. I understand the words but not the…

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.…

Is a mayonnaise emergent? A cook asks about weak and strong emergence

Is the flame on my burner a thing, or something that keeps happening?

When I stir stock the surface dips. What did Newton’s spinning bucket prove?

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,…

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…
