| 9052 | Vague predicates lack application; there are no borderline cases; vague F is not F [Unger, by Keefe/Smith] |
| Full Idea: In a slogan, Unger's thesis is that all vague predicates lack application ('nihilism', says Williamson). Classical logic can be retained in its entirety. There are no borderline cases: for vague F, everything is not F; nothing is either F or borderline F. | |
| From: report of Peter Unger (There are no ordinary things [1979]) by R Keefe / P Smith - Intro: Theories of Vagueness §1 | |
| A reaction: Vague F could be translated as 'I'm quite tempted to apply F', in which case Unger is right. This would go with Russell's view. Logic and reason need precise concepts. The only strategy with vagueness is to reason hypothetically. |
| 16070 | There are no objects with proper parts; there are only mereological simples [Unger, by Wasserman] |
| Full Idea: Eliminativism is often associated with Unger, who defends 'mereological nihilism', that there are no composite objects (objects with proper parts); there are only mereological simples (with no proper parts). The nihilist denies statues and ships. | |
| From: report of Peter Unger (There are no ordinary things [1979]) by Ryan Wasserman - Material Constitution 4 | |
| A reaction: The puzzle here is that he has a very clear notion of identity for the simples, but somehow bars combinations from having identity. So identity is simplicity? 'Complex identity' doesn't sound like an oxymoron. We're stuck if there are no simples. |
| 8724 | The meaning of 'know' does not change from courtroom to living room [Unger] |
| Full Idea: There is no reason to suppose that the meaning of 'know' changes from the courtroom to the living room and back again; no more than for supposing that 'vacuum' changes from the laboratory to the cannery. | |
| From: Peter Unger (Ignorance: a Case for Scepticism [1975], 2.1) | |
| A reaction: I disagree. Lots of words change their meaning (or reference) according to context. Flat, fast, tall, clever. She 'knows a lot' certainly requires a context. The bar of justification goes up and down, and 'knowledge' changes accordingly. |
| 8722 | No one knows anything, and no one is ever justified or reasonable [Unger] |
| Full Idea: I argue for the thesis that no one ever knows about anything, ...and that consequently no one is ever justified or at all reasonable in anything. | |
| From: Peter Unger (Ignorance: a Case for Scepticism [1975], Intro) | |
| A reaction: The premiss of his book seems to be that knowledge is assumed to require certainty, and is therefore impossible. Unger has helped push us to a more relaxed and fallibilist attitude to knowledge. 'No one is reasonable' is daft! |
| 3061 | Anaxarchus said that he was not even sure that he knew nothing [Anaxarchus, by Diog. Laertius] |
| Full Idea: Anaxarchus said that he was not even sure that he knew nothing. | |
| From: report of Anaxarchus (fragments/reports [c.340 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 09.10.1 |
| 8723 | An evil scientist may give you a momentary life, with totally false memories [Unger] |
| Full Idea: The evil scientist might not only be deceiving you with his electrodes; maybe he has just created you with your ostensible memory beliefs and experiences, and for good measure he will immediately destroy you, so in the next moment you no longer exist. | |
| From: Peter Unger (Ignorance: a Case for Scepticism [1975], 1.12) | |
| A reaction: This is based on Russell's scepticism about memory (Idea 2792). Even this very train of thought may not exist, if the first half of it was implanted, rather than being developed by you. I cannot see how to dispute this possibility. |
| 7602 | In the Bible God changes his mind (repenting of creating humanity, in the Flood) [Armstrong,K] |
| Full Idea: In the Bible God changes his mind, as when he repents of having made man and decides to destroy the human race in the Flood. | |
| From: Karen Armstrong (A History of God [1993], Ch.1) | |
| A reaction: It becomes apparent that the most startling feature of Christian fundamentalism is its uncritical reading of the Bible, in which passages are wilfully lifted from context, and inconvenient inconsistencies are ruthlessly ignored. |
| 7605 | Monotheism introduced intolerance into religious thinking [Armstrong,K] |
| Full Idea: We have become so used to the intolerance of monotheism that we may not appreciate that its hostility towards other gods was a new religious attitude; paganism was an essentially tolerant faith. | |
| From: Karen Armstrong (A History of God [1993], Ch.2) | |
| A reaction: The comedian Dave Allen always signed off with "may your god go with you". To me the most striking feature of monotheists is frequently their barely controlled aggression, beneath a mask of strained compassion. |
| 7599 | Around 800 BCE teachers superseded gods in India [Armstrong,K] |
| Full Idea: Around the eighth century BCE the gods ceased to be very important in India, and would be superseded by the religious teacher, who would be considered higher than the gods. | |
| From: Karen Armstrong (A History of God [1993], Ch.1) | |
| A reaction: At least there has been one culture that gave an appropriate status to teachers. It seems astonishing in that age that human beings could have higher status than gods - way before the European 'humanists'. |
| 7597 | There is virtually no sign of monotheism in the Pentateuch [Armstrong,K] |
| Full Idea: It is very difficult to find a single monotheistic statement in the whole of the Pentateuch, and even the Ten Commandments take the existence of other gods for granted ("There shall be no strange gods for you before my face"). | |
| From: Karen Armstrong (A History of God [1993], Ch.1) | |
| A reaction: The transition from polytheism to monotheism is very strange. First God is 'jealous' of other gods, then supremely above them, and eventually totally exclusive. It's like watching the rise of Stalin. |
| 7606 | The idea that Jesus was God was only settled in the fourth century [Armstrong,K] |
| Full Idea: Jesus himself certainly never claimed to be God, and the doctrine that Jesus had been God in human form was not finalised until the fourth century. | |
| From: Karen Armstrong (A History of God [1993], Ch.3) | |
| A reaction: It was this final view which seems to have provoked Muhammed into developing a religion with the slogan "there is only one God". In Christianity an initially promising set of teachings grew into a prolonged irrational hysteria. |
| 7596 | Faith is not just belief in propositions, but also putting trust in them [Armstrong,K] |
| Full Idea: There is a distinction between belief in a set of propositions and a faith which enables us to put our trust in them. | |
| From: Karen Armstrong (A History of God [1993], Intro) | |
| A reaction: This is interestingly distinct from the usual idea that faith is putting belief in propositions which are not sufficiently rationally justified. How many philosophers actually have faith in the propositions they say they believe? |
