Kierkegaard’s leap of faith: irrational, or beyond reason?
In Fear and Trembling (1843), written under the pseudonym Johannes de Silentio, Kierkegaard considers Abraham, who is ready to sacrifice Isaac at God's command. Johannes can't understand Abraham. He calls this a "teleological suspension of the ethical": Abraham's relation to God goes…

Al-Farabi’s Virtuous City and Plato’s Republic
Al-Farabi (c. 870–950) is sometimes called the "Second Teacher", after Aristotle. His Principles of the Opinions of the People of the Virtuous City combines Neoplatonic metaphysics with a political philosophy that owes a great deal to Plato's Republic. The virtuous city is…

Eliminative materialism: how can anyone claim that beliefs don’t exist?
Another beginner question from me, sorry. I read a short summary of Paul Churchland's eliminative materialism and I can't get past the first step. As I understand it, he says that our everyday way of explaining people ("she went to the shop…

How does one contradiction let you prove absolutely anything?
A friend studying computer science told me that in logic "a contradiction implies everything". If you accept one contradiction, you can prove the moon is green, that I'm a king, anything. This sounds like a trick. Contradictions are bad, sure, but why…

Diotima’s ladder: does loving the Form of Beauty make particular people disposable?
In the Symposium (210a–212a), Socrates reports Diotima's account of the ascent of love. The lover moves from one beautiful body to all beautiful bodies, then to beautiful souls, to practices and laws, to kinds of knowledge, and finally to Beauty itself. Gregory…

Zhuangzi’s happy fish: can we know what others feel?
In chapter 17 of the Zhuangzi, Zhuangzi and his friend the logician Huizi are strolling on a bridge over the river Hao. Zhuangzi remarks that the minnows darting about are happy. Huizi objects: you're not a fish, so how do you know…

What are the pramāṇas, and how do the schools disagree about them?
I grew up hearing words like "pramāṇa" in family discussions without really knowing what they meant. I've started reading Indian philosophy properly and keep running into lists of pramāṇas that differ between schools. What are they, and why does the number matter?

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,…

Is it irrational to want to be remembered after you die?
Founders talk a lot about "legacy". I've caught myself thinking about it too: building something that lasts after me. But I won't be around to enjoy being remembered. Epicurus argued that death is nothing to us, because when we exist death isn't…

What is functionalism, and why do people think it supports machine consciousness?
People in AI discussions often say that "on a functionalist view" a machine could be conscious. I have a vague sense of what that means but I'd like to understand it properly. What exactly does functionalism claim? Why do people think it…

Gandhi’s satyagraha as philosophy, not just a tactic
Gandhi coined the word satyāgraha, "holding firmly to truth", in South Africa around 1906–08. He distinguished it from "passive resistance", which he saw as the weapon of the weak. Satyāgraha requires the resister to accept suffering without retaliating, aiming to convert the…

Dream arguments East and West: Descartes, Zhuangzi and the Yoga Vasistha
Three treatments of the same worry. Descartes, Meditations I (1641): there are no sure signs to distinguish waking from dreaming, so the senses can't give certain knowledge. He uses it as a method, a step towards certainty. Zhuangzi, chapter 2: Zhuangzi dreams…

Is the liar paradox a problem about language or about truth itself?
Take the sentence: this sentence is false. If true, it's false; if false, it's true. Tarski's response (1933) was that a language can't consistently contain its own truth predicate, so we need a hierarchy: an object language, a metalanguage that talks about…

Did Indian mathematicians have a philosophy of zero?
Brahmagupta's Brāhmasphuṭasiddhānta (628 CE) gives rules for arithmetic with zero as a number: adding zero to a number leaves it unchanged, multiplying by zero gives zero, and so on. He also tried to define division by zero, not quite successfully. Earlier, the…

Hart’s “internal point of view”, seen from a courtroom in Lahore
Hart distinguishes being obliged to do something (as when a gunman demands your money) from having an obligation (as under a legal rule). The difference lies in the internal point of view: officials, especially judges, accept the rule of recognition as a…

Who is morally responsible when an AI system causes harm?
Andreas Matthias coined the term "responsibility gap" in 2004: when a learning system behaves in ways its designers couldn't predict, it seems nobody is fully responsible. The designers didn't intend the outcome, the operators couldn't foresee it, and the system isn't a…

Why is saying “I promise” not true or false, like other sentences?
I found an idea I don't fully understand. The book says that when I tell my mother "I promise I'll be home by ten", I am not describing anything. I am not reporting a promise that exists somewhere else. Saying it is…

Is “objectivity” in journalism a coherent ideal?
I was trained to be "objective": report the facts, present both sides, keep my opinions out. In practice, every choice is a judgment: what's a story, whose voice to include, which word to use (killed or died, militant or freedom fighter). Some…

Ibn Khaldun on taxation: a fourteenth-century Laffer curve?
In the Muqaddimah (1377) Ibn Khaldun observes that at the beginning of a dynasty, taxation yields a large revenue from small assessments, while at the end of a dynasty it yields a small revenue from large assessments. Arthur Laffer himself credited Ibn…

What’s the difference between negative and positive liberty?
In constitutional law classes, Isaiah Berlin's "Two Concepts of Liberty" (1958) comes up constantly, but my professors use it in different ways. Some say negative liberty is freedom from interference and positive liberty is having the resources to act. Others say positive…

Do future generations have rights over the climate we leave them?
Around Hyderabad's lakes you can see the long-term effects of decisions made decades ago: dams, drained wetlands, groundwater extraction. The people most affected weren't born when the decisions were made. Derek Parfit's "non-identity problem" (Reasons and Persons, 1984) makes this hard. Our…

If I must file the return, must I file it or shred it? Ross’s paradox for a tax preparer
A client's son, who is studying philosophy, told me about something called Ross's paradox. As he explained it: in the standard logic of obligation, if you ought to do A, then it follows that you ought to do "A or B", for…

What is ijtihad, and why did Iqbal call it the principle of movement in Islam?
From my law studies I know ijtihad in its narrow legal sense: independent reasoning by a qualified jurist to derive a ruling where texts are silent or unclear. But Iqbal, in the sixth lecture of the Reconstruction, "The Principle of Movement in…

My son says our choices can’t harm people who don’t exist yet. What is the non-identity problem?
There is a famous puzzle, my son tells me, the "non-identity problem", which shows that we cannot make future people worse off by damaging the environment, because different choices would mean different people being born. This makes no sense to me. My…

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…

Did Ibn Khaldun invent sociology, or is that a modern compliment?
Ibn Khaldun called his new science 'ilm al-'umran, the science of human social organisation or civilisation. He looked for regular causes behind historical events: climate, economy, group solidarity, the transition from nomadic to urban life. Many modern writers call him the founder…

What’s the difference between the cosmological and the ontological argument?
First-year question, sorry. In my philosophy of religion module the lecturer moved fast through several arguments for God's existence and I came out mixing up two of them. I think one is about causes and one is about the concept of God,…

Why is “begging the question” not the same as “raising the question”?
My students, and frankly most newspapers, use "this begs the question" to mean "this raises the question". A colleague told me that's wrong and the phrase refers to a fallacy. Could someone explain the fallacy properly, with a clear example, and where…

Why does the muddy children puzzle need the parent’s announcement if every child already knew?

Can someone explain Ramanuja’s Vishishtadvaita fairly, from an Advaitin’s point of view?
I confess I have never given Rāmānuja the attention he deserves. My Vaishnava friends tell me I misrepresent him whenever I speak about him. So I ask, in good faith: what exactly is Vishishtadvaita, "qualified non-dualism"? How does it differ from Advaita…
