20 ideas
1813 | All reasoning endlessly leads to further reasoning (Mode 12) [Agrippa, by Diog. Laertius] |
Full Idea: Twelfth mode: all reasoning leads on to further reasoning, and this process goes on forever. | |
From: report of Agrippa (fragments/reports [c.60]) by Diogenes Laertius - Lives of Eminent Philosophers 09.Py.10 |
1811 | Proofs often presuppose the thing to be proved (Mode 15) [Agrippa, by Diog. Laertius] |
Full Idea: Fifteenth mode: proofs often presuppose the thing to be proved. | |
From: report of Agrippa (fragments/reports [c.60]) by Diogenes Laertius - Lives of Eminent Philosophers 09.Py.10 |
1815 | Reasoning needs arbitrary faith in preliminary hypotheses (Mode 14) [Agrippa, by Diog. Laertius] |
Full Idea: Fourteenth mode: reasoning requires arbitrary faith in preliminary hypotheses. | |
From: report of Agrippa (fragments/reports [c.60]) by Diogenes Laertius - Lives of Eminent Philosophers 09.Py.10 |
1812 | All discussion is full of uncertainty and contradiction (Mode 11) [Agrippa, by Diog. Laertius] |
Full Idea: Eleventh mode: all topics of discussion are full of uncertainty and contradiction. | |
From: report of Agrippa (fragments/reports [c.60]) by Diogenes Laertius - Lives of Eminent Philosophers 09.Py.10 |
4568 | If 'Queen of England' does not refer if there is no queen, its meaning can't refer if there is one [Cooper,DE] |
Full Idea: If 'the Queen of England' is not a referring expression when there is no queen, nor can it be one when there is a queen - since the meaning of the expression is the same in either case. | |
From: David E. Cooper (Philosophy and the Nature of Language [1973], §4.1) | |
A reaction: I'm not convinced. Does this mean that since I can point with my finger at nothing, I therefore do not indicate anything when there is an object at which I am pointing. Sounds silly to me. |
4574 | If some peoples do not have categories like time or cause, they can't be essential features of rationality [Cooper,DE] |
Full Idea: If our most basic concepts, like time, space, substance or causality, are not shared by some peoples, it puts paid to the cherished ideal of philosophers to discover a set of concepts or categories which any rational human must employ in his thinking. | |
From: David E. Cooper (Philosophy and the Nature of Language [1973], §5.2) | |
A reaction: This seems to be a place where a priori philosophy (Aristotle,Kant,Hegel) meets empirical research (Whorf). However, interpreting the research is so fraught with problems it drives you back to the a priori… |
8850 | Agrippa's Trilemma: justification is infinite, or ends arbitrarily, or is circular [Agrippa, by Williams,M] |
Full Idea: Agrippa's Trilemma offers three possible outcomes for a regress of justification: the chain goes on for ever (infinite); or the chain stops at an unjustified proposition (arbitrary); or the chain eventually includes the original proposition (circular). | |
From: report of Agrippa (fragments/reports [c.60], §2) by Michael Williams - Without Immediate Justification §2 | |
A reaction: This summarises Ideas 1911, 1913 and 1914. Agrippa's Trilemma is now a standard starting point for modern discussions of foundations. Personally I reject 2, and am torn between 1 (+ social consensus) and 3 (with a benign, coherent circle). |
1814 | Everything is perceived in relation to another thing (Mode 13) [Agrippa, by Diog. Laertius] |
Full Idea: Thirteenth mode: everything is always perceived in relation to something else. | |
From: report of Agrippa (fragments/reports [c.60]) by Diogenes Laertius - Lives of Eminent Philosophers 09.Py.10 |
4573 | If it is claimed that language correlates with culture, we must be able to identify the two independently [Cooper,DE] |
Full Idea: If it is claimed that linguistic differences significantly correlate with cultural differences, it must therefore be possible to identify the linguistic differences independently from the cultural ones. | |
From: David E. Cooper (Philosophy and the Nature of Language [1973], §5.1) | |
A reaction: This is a basic objection to any extreme relativist version of the S-P hypothesis. They are part of the conspiracy to overemphasise language in philosophy, and they are wrong. |
4575 | A person's language doesn't prove their concepts, but how are concepts deduced apart from language? [Cooper,DE] |
Full Idea: It would be absurd to say the Hopi lack the concept of time because they lack tensed verbs, ..but how do we find out what a man's concepts are except in terms of his language? | |
From: David E. Cooper (Philosophy and the Nature of Language [1973], §5.2) | |
A reaction: Presumably we should look at animals, where concepts must be inferred in order to explain behaviour. I don't see why introspection (scientifically wicked) should not also be employed to detect our own non-verbal concepts. How are new words invented? |
7296 | 'Grue' is not a colour [Milsted] |
Full Idea: 'Grue' is not a colour. | |
From: Tom Milsted (talk [2006]), quoted by PG - Db (ideas) | |
A reaction: This simple observation strikes me as rather crucial in assessing Goodman's paradox. Blue is a colour, but grue is some sort of behaviour. Blue is a secondary quality, but grue seems to be a primary quality. |
4561 | Many sentences set up dispositions which are irrelevant to the meanings of the sentences [Cooper,DE] |
Full Idea: Many sentences set up dispositions which are irrelevant to the meanings of the sentences. | |
From: David E. Cooper (Philosophy and the Nature of Language [1973], §2.3) | |
A reaction: Yet another telling objection to behaviourism. When I look at broccoli I may have a disposition to be sick, but that isn't part of the concept of broccoli. |
4564 | I can meaningfully speculate that humans may have experiences currently impossible for us [Cooper,DE] |
Full Idea: It is not meaningless for me to postulate the potential for humans to sense in a manner which is at present unimaginable and indescribable. There is no reason to believe me, but I might be right. | |
From: David E. Cooper (Philosophy and the Nature of Language [1973], §3.1) | |
A reaction: The key counterexample to verificationist theories of meaning is wild speculations, which are clearly meaningful, though frequently far beyond any likely human experience. Logical positivists are allergic to imagination. |
4565 | The verification principle itself seems neither analytic nor verifiable [Cooper,DE] |
Full Idea: It seems that the positivists must admit that there is at least one statement which is meaningful, but which is neither verifiable nor analytic - namely, the statement of the principle of verification itself. | |
From: David E. Cooper (Philosophy and the Nature of Language [1973], §3.1) | |
A reaction: Some people think this objection is decisive, but I think any theory must be permitted a few metatheoretic assertions or axioms which are beyond discussion. Ayer thought the VP might be treated as analytic. Everyone has to start somewhere. |
4563 | 'How now brown cow?' is used for elocution, but this says nothing about its meaning [Cooper,DE] |
Full Idea: The sentence 'How now brown cow?' has its use in elocutions classes, yet this aspect of its use tells us nothing about its meaning. | |
From: David E. Cooper (Philosophy and the Nature of Language [1973], §2.4) | |
A reaction: Indeed, and also there are weird sentence of which we can assemble a meaning, but cannot think of any conceivable use ('rats swim in purple marmalade'). |
4562 | Most people know how to use the word "Amen", but they do not know what it means [Cooper,DE] |
Full Idea: Most people know how to use the word "Amen", but they do not know what it means. | |
From: David E. Cooper (Philosophy and the Nature of Language [1973], §2.4) | |
A reaction: Personally I find examples like this decisive against the 'use' theory of meaning. Maybe the defence is that the theory works for sentences, and individual words (like passwords) are peripheral. |
4571 | Reference need not be a hit-or-miss affair [Cooper,DE] |
Full Idea: Reference need not be a hit-or-miss affair. | |
From: David E. Cooper (Philosophy and the Nature of Language [1973], §4.2) | |
A reaction: Sounds right. If the basic scenario is picking someone out in a crowd, your listener may think they know which person you are talking about, with a high degree of probability. |
4566 | Any thesis about reference is also a thesis about what exists to be referred to [Cooper,DE] |
Full Idea: Any thesis about reference is also going to be a thesis about what there is in existence to refer to. | |
From: David E. Cooper (Philosophy and the Nature of Language [1973], §4) | |
A reaction: I see the point, but we must not put the cart before the horse. I may have an intuition that something exists, but not know how to refer to it (because of my small vocabulary). |
4572 | If predicates name things, that reduces every sentence to a mere list of names [Cooper,DE] |
Full Idea: If predicates are names of entities, then subject/predicate sentences are pairs of names, since subjects are names (or referring expressions). But a pair of names is not a sentence at all, it is a mere list. | |
From: David E. Cooper (Philosophy and the Nature of Language [1973], §4.4) | |
A reaction: If that is meant to demolish universals it is too quick. Concatenating names is not the same as listing them. A relationship is asserted. There is a (mysterious) Platonic 'partaking' between form and particular. Perhaps. |
4576 | An analytic truth is one which becomes a logical truth when some synonyms have been replaced [Cooper,DE] |
Full Idea: The definition of analytic truth which has, I believe, the most chance of success is one in terms of synonymy; ..an analytic truth is one which can be transformed into a logical truth once synonyms are replaced by synonyms. | |
From: David E. Cooper (Philosophy and the Nature of Language [1973], §7.1) | |
A reaction: Sounds promising, though there is Quine's notorious problem of circularity in all these concepts. If synonymy is conventional, then so is analyticity. I personally feel that the circle can be broken. |
