50 ideas
21887 | Derrida focuses on other philosophers, rather than on science [Derrida] |
Full Idea: We should focus on other philosophers, and not on science. | |
From: Jacques Derrida (works [1990]), quoted by Barry Stocker - Derrida on Deconstruction |
21888 | Philosophy is just a linguistic display [Derrida] |
Full Idea: Philosophy is entirely linguistic, and is a display. | |
From: Jacques Derrida (works [1990]), quoted by Barry Stocker - Derrida on Deconstruction |
21896 | Philosophy aims to build foundations for thought [Derrida, by May] |
Full Idea: Derrida points out that the project of philosophy consists largely in attempting to build foundations for thought. | |
From: report of Jacques Derrida (works [1990]) by Todd May - Gilles Deleuze 1.04 | |
A reaction: You would first need to be convinced that there could be such a thing as foundations for thinking. Derrida thinks the project is hopeless. I think of it more as building an ideal framework for thought. |
21893 | Philosophy is necessarily metaphorical, and its writing is aesthetic [Derrida] |
Full Idea: All of philosophy is necessarily metaphorical, and hence aesthetic. | |
From: Jacques Derrida (works [1990]), quoted by Barry Stocker - Derrida on Deconstruction |
21892 | Interpretations can be interpreted, so there is no original 'meaning' available [Derrida] |
Full Idea: Because interpretations of texts can be interpreted, they can therefore have no 'original meaning'. | |
From: Jacques Derrida (works [1990]), quoted by Barry Stocker - Derrida on Deconstruction |
20925 | Hermeneutics blunts truth, by conforming it to the interpreter [Derrida, by Zimmermann,J] |
Full Idea: Derrida worried that hermeneutics blunts the disruptive power of truth by forcing it conform to the interpreter's mental horizon. | |
From: report of Jacques Derrida (works [1990]) by Jens Zimmermann - Hermeneutics: a very short introduction 3 'The heart' | |
A reaction: Good heavens - I agree with Derrida. Very French, though, to see the value of truth in its disruptiveness. I tend to find the truth reassuring, but then I'm English. |
20934 | Hermeneutics is hostile, trying to overcome the other person's difference [Derrida, by Zimmermann,J] |
Full Idea: Derrida described the hermeneutic impulse to understand another as a form of violence that seeks to overcome the other's particularity and unique difference. | |
From: report of Jacques Derrida (works [1990]) by Jens Zimmermann - Hermeneutics: a very short introduction App 'Derrida' | |
A reaction: I'm not sure about 'violence', but Derrida was on to somethng here. The 'hermeneutic circle' sounds like a creepy process of absorption, where the original writer disappears in a whirlpool of interpretation. |
21895 | Structuralism destroys awareness of dynamic meaning [Derrida] |
Full Idea: Structuralism destroys awareness of dynamic meaning. | |
From: Jacques Derrida (works [1990]), quoted by Barry Stocker - Derrida on Deconstruction |
21934 | The idea of being as persistent presence, and meaning as conscious intelligibility, are self-destructive [Derrida, by Glendinning] |
Full Idea: The tradition of conceiving being in terms of persisting presence, and meaning in terms of pure intelligibility or logos potentially present to the mind, finds itself dismantled by resources internal to its own construction. | |
From: report of Jacques Derrida (works [1990]) by Simon Glendinning - Derrida: A Very Short Introduction 6 | |
A reaction: [compressed] Glendinning says this is the basic meaning of de-construction. My personal reading of this is that Aristotle is right, and grand talk of Being is hopeless, so we should just aim to understand objects. I also believe in propositions. |
21883 | Sincerity can't be verified, so fiction infuses speech, and hence reality also [Derrida] |
Full Idea: Sincerity can never be verified, so fiction infuses all speech, which means that reality is also fictional. | |
From: Jacques Derrida (works [1990]), quoted by Barry Stocker - Derrida on Deconstruction |
21882 | Sentences are contradictory, as they have opposite meanings in some contexts [Derrida] |
Full Idea: Sentences are implicitly contradictory, because they can be used differently in different contexts (most obviously in 'I am ill'). | |
From: Jacques Derrida (works [1990]), quoted by Barry Stocker - Derrida on Deconstruction |
21881 | We aim to explore the limits of expression (as in Mallarmé's poetry) [Derrida] |
Full Idea: The aim is to explore the limits of expression (which is what makes the poetry of Mallarmé so important). | |
From: Jacques Derrida (works [1990]), quoted by Barry Stocker - Derrida on Deconstruction |
18781 | Inconsistency doesn't prevent us reasoning about some system [Mares] |
Full Idea: We are able to reason about inconsistent beliefs, stories, and theories in useful and important ways | |
From: Edwin D. Mares (Negation [2014], 1) |
4756 | Derrida says that all truth-talk is merely metaphor [Derrida, by Engel] |
Full Idea: Derrida's view is that every discourse is metaphorical, and there is no difference between truth-talk and metaphor. | |
From: report of Jacques Derrida (works [1990]) by Pascal Engel - Truth §2.5 | |
A reaction: Right. Note that this is a Frenchman's summary. How would one define metaphor, without mentioning that it is parasitic on truth? Certainly some language tries to be metaphor, and other language tries not to be. |
21877 | True thoughts are inaccessible, in the subconscious, prior to speech or writing [Derrida] |
Full Idea: 'True' thoughts are inaccessible, buried in the subconscious, long before they get to speech or writing. | |
From: Jacques Derrida (works [1990]), quoted by Barry Stocker - Derrida on Deconstruction | |
A reaction: [My reading of some Derrida produced no quotations. I've read two commentaries, which were obscure. The Derrida ideas in this db are my simplistic tertiary summaries. Experts can chuckle over my failure] |
18790 | Intuitionism as natural deduction has no rule for negation [Mares] |
Full Idea: In intuitionist logic each connective has one introduction and one elimination rule attached to it, but in the classical system we have to add an extra rule for negation. | |
From: Edwin D. Mares (Negation [2014], 5.5) | |
A reaction: How very intriguing. Mares says there are other ways to achieve classical logic, but they all seem rather cumbersome. |
18789 | Intuitionist logic looks best as natural deduction [Mares] |
Full Idea: Intuitionist logic appears most attractive in the form of a natural deduction system. | |
From: Edwin D. Mares (Negation [2014], 5.5) |
18787 | Three-valued logic is useful for a theory of presupposition [Mares] |
Full Idea: One reason for wanting a three-valued logic is to act as a basis of a theory of presupposition. | |
From: Edwin D. Mares (Negation [2014], 3.1) | |
A reaction: [He cites Strawson 1950] The point is that you can get a result when the presupposition does not apply, as in talk of the 'present King of France'. |
18793 | Material implication (and classical logic) considers nothing but truth values for implications [Mares] |
Full Idea: The problem with material implication, and classical logic more generally, is that it considers only the truth value of formulas in deciding whether to make an implication stand between them. It ignores everything else. | |
From: Edwin D. Mares (Negation [2014], 7.1) | |
A reaction: The obvious problem case is conditionals, and relevance is an obvious extra principle that comes to mind. |
18784 | In classical logic the connectives can be related elegantly, as in De Morgan's laws [Mares] |
Full Idea: Among the virtues of classical logic is the fact that the connectives are related to one another in elegant ways that often involved negation. For example, De Morgan's Laws, which involve negation, disjunction and conjunction. | |
From: Edwin D. Mares (Negation [2014], 2.2) | |
A reaction: Mares says these enable us to take disjunction or conjunction as primitive, and then define one in terms of the other, using negation as the tool. |
18786 | Excluded middle standardly implies bivalence; attacks use non-contradiction, De M 3, or double negation [Mares] |
Full Idea: On its standard reading, excluded middle tells us that bivalence holds. To reject excluded middle, we must reject either non-contradiction, or ¬(A∧B) ↔ (¬A∨¬B) [De Morgan 3], or the principle of double negation. All have been tried. | |
From: Edwin D. Mares (Negation [2014], 2.2) |
18780 | Standard disjunction and negation force us to accept the principle of bivalence [Mares] |
Full Idea: If we treat disjunction in the standard way and take the negation of a statement A to mean that A is false, accepting excluded middle forces us also to accept the principle of bivalence, which is the dictum that every statement is either true or false. | |
From: Edwin D. Mares (Negation [2014], 1) | |
A reaction: Mates's point is to show that passively taking the normal account of negation for granted has important implications. |
18782 | The connectives are studied either through model theory or through proof theory [Mares] |
Full Idea: In studying the logical connectives, philosophers of logic typically adopt the perspective of either model theory (givng truth conditions of various parts of the language), or of proof theory (where use in a proof system gives the connective's meaning). | |
From: Edwin D. Mares (Negation [2014], 1) | |
A reaction: [compressed] The commonest proof theory is natural deduction, giving rules for introduction and elimination. Mates suggests moving between the two views is illuminating. |
21878 | Names have a subjective aspect, especially the role of our own name [Derrida] |
Full Idea: We can give a subjective account of names, by considering our own name. | |
From: Jacques Derrida (works [1990]), quoted by Barry Stocker - Derrida on Deconstruction |
21889 | 'I' is the perfect name, because it denotes without description [Derrida] |
Full Idea: 'I' is the perfect name, because it denotes without description. | |
From: Jacques Derrida (works [1990]), quoted by Barry Stocker - Derrida on Deconstruction |
21879 | Even Kripke can't explain names; the word is the thing, and the thing is the word [Derrida] |
Full Idea: Even Kripke can't explain names, because the word is the thing, and also the thing is the word. | |
From: Jacques Derrida (works [1990]), quoted by Barry Stocker - Derrida on Deconstruction |
18783 | Many-valued logics lack a natural deduction system [Mares] |
Full Idea: Many-valued logics do not have reasonable natural deduction systems. | |
From: Edwin D. Mares (Negation [2014], 1) |
18792 | Situation semantics for logics: not possible worlds, but information in situations [Mares] |
Full Idea: Situation semantics for logics consider not what is true in worlds, but what information is contained in situations. | |
From: Edwin D. Mares (Negation [2014], 6.2) | |
A reaction: Since many theoretical physicists seem to think that 'information' might be the most basic concept of a natural ontology, this proposal is obviously rather appealing. Barwise and Perry are the authors of the theory. |
18785 | Consistency is semantic, but non-contradiction is syntactic [Mares] |
Full Idea: The difference between the principle of consistency and the principle of non-contradiction is that the former must be stated in a semantic metalanguage, whereas the latter is a thesis of logical systems. | |
From: Edwin D. Mares (Negation [2014], 2.2) |
18788 | For intuitionists there are not numbers and sets, but processes of counting and collecting [Mares] |
Full Idea: For the intuitionist, talk of mathematical objects is rather misleading. For them, there really isn't anything that we should call the natural numbers, but instead there is counting. What intuitionists study are processes, such as counting and collecting. | |
From: Edwin D. Mares (Negation [2014], 5.1) | |
A reaction: That is the first time I have seen mathematical intuitionism described in a way that made it seem attractive. One might compare it to a metaphysics based on processes. Apparently intuitionists struggle with infinite sets and real numbers. |
21890 | Heidegger showed that passing time is the key to consciousness [Derrida] |
Full Idea: Heidegger showed us the importance of transient time for consciousness. | |
From: Jacques Derrida (works [1990]), quoted by Barry Stocker - Derrida on Deconstruction |
21880 | 'Tacit theory' controls our thinking (which is why Freud is important) [Derrida] |
Full Idea: All thought is controlled by tacit theory (which is why Freud is so important). | |
From: Jacques Derrida (works [1990]), quoted by Barry Stocker - Derrida on Deconstruction | |
A reaction: This idea is said to be the essential thought of Derrida's Deconstruction. The aim is liberation of thought, by identifying and bypassing these tacit metaphysical schemas. |
21884 | Capacity for repetitions is the hallmark of language [Derrida] |
Full Idea: The capacity for repetitions is the hallmark of language. | |
From: Jacques Derrida (works [1990]), quoted by Barry Stocker - Derrida on Deconstruction |
21935 | The sign is only conceivable as a movement between elusive presences [Derrida] |
Full Idea: The sign is conceivable only on the basis of the presence that it defers, and moving toward the deferred presence that it aims to reappropriate. | |
From: Jacques Derrida (works [1990]), quoted by Simon Glendinning - Derrida: A Very Short Introduction 6 | |
A reaction: [Glendinning gives no source for this] I take the fundamental idea to be that meanings are dynamic, when they are traditionally understood as static (and specifiable in dictionaries). |
21930 | For Aristotle all proper nouns must have a single sense, which is the purpose of language [Derrida] |
Full Idea: A noun [for Aristotle] is proper when it has but a single sense. Better, it is only in this case that it is properly a noun. Univocity is the essence, or better, the telos of language. | |
From: Jacques Derrida (works [1990]), quoted by Simon Glendinning - Derrida: A Very Short Introduction 5 | |
A reaction: [no ref given] His target seem to be Aristotelian definition, and also formal logic, which usually needs unambiguous meanings. {I'm puzzled that he thinks 'telos' is simply better than 'essence', since it is quite different]. |
21933 | Writing functions even if the sender or the receiver are absent [Derrida, by Glendinning] |
Full Idea: Writing can and must be able to do without the presence of the sender. ...Also writing can and must he able to do without the presence of the receiver. | |
From: report of Jacques Derrida (works [1990]) by Simon Glendinning - Derrida: A Very Short Introduction 6 | |
A reaction: In simple terms, one of them could die during the transmission. This is the grounds for the assertion of the primacy of writing. It opposes orthodox views which define language in terms of sender and receiver. |
21894 | Madness and instability ('the demonic hyperbole') lurks in all language [Derrida] |
Full Idea: Madness and instability ('the demonic hyperbole') lurks behind all language. | |
From: Jacques Derrida (works [1990]), quoted by Barry Stocker - Derrida on Deconstruction |
21886 | Meanings depend on differences and contrasts [Derrida] |
Full Idea: Meaning depends on 'differences' (contrasts). | |
From: Jacques Derrida (works [1990]), quoted by Barry Stocker - Derrida on Deconstruction |
21931 | 'Dissemination' is opposed to polysemia, since that is irreducible, because of multiple understandings [Derrida, by Glendinning] |
Full Idea: The intention to oppose polysemia with dissemination does not aim to affirm that everything we say is ambiguous, but that polysemia is irreducible in the sense that each and every 'meaning' is itself subject to more than one understanding. | |
From: report of Jacques Derrida (works [1990]) by Simon Glendinning - Derrida: A Very Short Introduction 5 | |
A reaction: The key point, I think, is that ambiguity and polysemia are not failures of language (which is the way most logicians see it), but part of the essential and irreducible nature of language. Nietzsche started this line of thought. |
21885 | Words exist in 'spacing', so meanings are never synchronic except in writing [Derrida] |
Full Idea: Words only exist is 'spacings' (of time and space), so there are no synchronic meanings (except perhaps in writing). | |
From: Jacques Derrida (works [1990]), quoted by Barry Stocker - Derrida on Deconstruction |
18791 | In 'situation semantics' our main concepts are abstracted from situations [Mares] |
Full Idea: In 'situation semantics' individuals, properties, facts, and events are treated as abstractions from situations. | |
From: Edwin D. Mares (Negation [2014], 6.1) | |
A reaction: [Barwise and Perry 1983 are cited] Since I take the process of abstraction to be basic to thought, I am delighted to learn that someone has developed a formal theory based on it. I am immediately sympathetic to situation semantics. |
7357 | People who control others with fluent language often end up being hated [Kongzi (Confucius)] |
Full Idea: Of what use is eloquence? He who engages in fluency of words to control men often finds himself hated by them. | |
From: Kongzi (Confucius) (The Analects (Lunyu) [c.511 BCE], V.5) | |
A reaction: I don't recall Socrates making this very good point to any of the sophists (such as Gorgias). The idea that if you battle or connive your way to dominance over others then you are successful is false. Life is a much longer game than that. |
7358 | All men prefer outward appearance to true excellence [Kongzi (Confucius)] |
Full Idea: I have yet to meet a man as fond of excellence as he is of outward appearances. | |
From: Kongzi (Confucius) (The Analects (Lunyu) [c.511 BCE], IX.18) | |
A reaction: Interestingly, this cynical view of the love of virtue is put by Plato into the mouths of Glaucon and Adeimantus (in Bk II of 'Republic', e.g. Idea 12), and not into the mouth of Socrates, who goes on to defend the possibility of true virtue. |
7362 | Humans are similar, but social conventions drive us apart (sages and idiots being the exceptions) [Kongzi (Confucius)] |
Full Idea: In our natures we approximate one another; habits put us further and further apart. The only ones who do not change are sages and idiots. | |
From: Kongzi (Confucius) (The Analects (Lunyu) [c.511 BCE], XVII.2) | |
A reaction: I find most of Confucius rather uninteresting, but this is a splendid remark about the influence of social conventions on human nature. Sages can achieve universal morality if they rise above social convention, and seek the true virtues of human nature. |
21891 | The good is implicitly violent (against evil), so there is no pure good [Derrida] |
Full Idea: Even the good is implicitly violent (against evil), so there can be no 'pure' good. | |
From: Jacques Derrida (works [1990]), quoted by Barry Stocker - Derrida on Deconstruction | |
A reaction: Is good implicitly non-violent? Appropriate anger seems to be good behaviour, and I can't see why it is impure. Maybe anger and violence lack the control needed for pure goodness. |
7360 | Do not do to others what you would not desire yourself [Kongzi (Confucius)] |
Full Idea: Do not do to others what you would not desire yourself. Then you will have no enemies, either in the state or in your home. | |
From: Kongzi (Confucius) (The Analects (Lunyu) [c.511 BCE], XII.2) | |
A reaction: The Golden Rule, but note the second sentence. Logically, it leads to the absurdity of not giving someone an Elvis record for Christmas because you yourself don't like Elvis. Kant (Idea 3733) and Nietzsche (Idea 4560) offer good criticisms. |
7359 | Excess and deficiency are equally at fault [Kongzi (Confucius)] |
Full Idea: Excess and deficiency are equally at fault. | |
From: Kongzi (Confucius) (The Analects (Lunyu) [c.511 BCE], XI.16) | |
A reaction: This is the sort of wisdom we admire in Aristotle (and in any sensible person), but it may also be the deepest motto of conservatism, and it is a long way from romantic philosophy, and the clarion call of Nietzsche to greater excitement in life. |
7363 | The virtues of the best people are humility, maganimity, sincerity, diligence, and graciousness [Kongzi (Confucius)] |
Full Idea: He who in this world can practise five things may indeed be considered Man-at-his-best: humility, maganimity, sincerity, diligence, and graciousness. | |
From: Kongzi (Confucius) (The Analects (Lunyu) [c.511 BCE], XVII.5) | |
A reaction: A very nice list. Who could resist working with a colleague who had such virtues? Who could go wrong if they married a person who had them? I can't think of anything important that is missing. |
7361 | Men of the highest calibre avoid political life completely [Kongzi (Confucius)] |
Full Idea: Men of the highest calibre avoid political life completely. | |
From: Kongzi (Confucius) (The Analects (Lunyu) [c.511 BCE], XIV.37) | |
A reaction: Plato notes that such people tend to avoid political life (and a left sheltering, as if from a wild storm!), but he thinks they should be dragged into the political arena for the common good. Confucius seems to approve of the avoidance. Plato is right. |
23393 | Confucianism assumes that all good developments have happened, and there is only one Way [Norden on Kongzi (Confucius)] |
Full Idea: The two major limitations of Confucianism are that it assumes that all worthwhile cultural, social and ethical innovation has already occurred, and that it does not recognise the plurality of worthwhile ways of life. | |
From: comment on Kongzi (Confucius) (The Analects (Lunyu) [c.511 BCE]) by Bryan van Norden - Intro to Classical Chinese Philosophy 3.III | |
A reaction: In modern liberal terms that is about as conservative as it is possible to get. We think of it as the state of mind of an old person who can only long for the way things were when they were young. But 'hold fast to that which is good'! |
