21900 | Deleuze relies on Spinoza (immanence), Bergson (duration), and difference (Nietzsche) [May] |
Full Idea: The three tripods on which the philosophy of Deleuze stands are immanence (Spinoza), duration (Bergson), and the affirmation of difference (Nietzsche). | |
From: Todd May (Gilles Deleuze [2006], 2.12) | |
A reaction: [Just to begin sketching how continental philosophy sees its tradition]. |
17377 | All descriptive language is classificatory [Dupré] |
Full Idea: Classification pervades any descriptive use of language whatever. | |
From: John Dupré (The Disorder of Things [1993], 1) | |
A reaction: This is because, as Aristotle well knew, language consists almost entirely of universals (apart from the proper names). Language just is classification. |
17376 | We should aim for a classification which tells us as much as possible about the object [Dupré] |
Full Idea: The most important desideratum of a classificatory scheme is that assigning an object to a particular classification tell us as much as possible about that object. | |
From: John Dupré (The Disorder of Things [1993], Ch 1) | |
A reaction: We should probably say that the aim is a successful explanation, rather than a heap of information. If we are totally baffled by a particular type of object, it is presumably important to group the instances together, to focus the bafflement. |
17390 | Natural kinds don't need essentialism to be explanatory [Dupré] |
Full Idea: The importance of natural kinds for explanation does not depend on a doctrine of essences. | |
From: John Dupré (The Disorder of Things [1993], 3) | |
A reaction: He suggest as the alternative that laws do the explaining, employing natural kinds. He allows that individual essences might be explanatory. |
17389 | A species might have its essential genetic mechanism replaced by a new one [Dupré] |
Full Idea: Contradicting one of the main points of essentialism, there is no reason in principle why a species should not survive the demise of its current genetic mechanisms (some other species coherence gradually taking over). | |
From: John Dupré (The Disorder of Things [1993], 2) | |
A reaction: I would say that this meant that the species had a new essence, because I don't take what is essential to be the same as what is necessary. The new genetics would replace the old as the basic explanation of the species. |
17388 | It seems that species lack essential properties, so they can't be natural kinds [Dupré] |
Full Idea: It is widely agreed among biologists that no essential property can be found to demarcate species, so that if an essential property is necessary for a natural kind, species are not natural kinds. | |
From: John Dupré (The Disorder of Things [1993], 2) | |
A reaction: This uses 'essential' to mean 'necessary', but I would use 'essential' to mean 'deeply explanatory'. Biological species are, nevertheless, dubious members of an ontological system. Vegetables are the problem. |
17374 | The possibility of prediction rests on determinism [Dupré] |
Full Idea: Determinism is the metaphysical underlay of the possibility of prediction. | |
From: John Dupré (The Disorder of Things [1993], Intro) | |
A reaction: Not convinced. There might be micro-indeterminacies which iron out into macro-regularities. |
17378 | Presumably molecular structure seems important because we never have the Twin Earth experience [Dupré] |
Full Idea: It is surely the absence of experiences like the one Putnam describes that makes it reasonable to attach to molecular structure at least most of the importance that Putnam ascribes to it. | |
From: John Dupré (The Disorder of Things [1993], 1) | |
A reaction: That is, whenever we experience water-like stuff, it always turns out to have the same molecular structure. Twin Earth is a nice thought experiment, except that XZY is virtually inconceivable. |
23110 | Human injustice is not a permanent feature of communities [Rawls] |
Full Idea: Men's propensity to injustice is not a permanent aspect of community life. | |
From: John Rawls (A Theory of Justice [1972], p.245), quoted by John Kekes - Against Liberalism | |
A reaction: This attitude is dismissed by Kekes, with some justification, as naïve optimism. What could be Rawls's grounds for making such a claim? It couldn't be the facts of human history. |
15676 | Rawls defends the priority of right over good [Rawls, by Finlayson] |
Full Idea: Rawls defends the thesis of the priority of the right over the good. | |
From: report of John Rawls (A Theory of Justice [1972]) by James Gordon Finlayson - Habermas Ch.7:100 | |
A reaction: It depends whether you are talking about actions, or about states of affairs. I don't see how any state of affairs can be preferred to the good one. It may be that the highest duty of action is to do what is right, rather than to achieve what is good. |
4123 | A fair arrangement is one that parties can agree to without knowing how it will benefit them personally [Rawls, by Williams,B] |
Full Idea: Rawls's theory is an elaboration of a simple idea: a fair system of arrangements is one that the parties can agree to without knowing how it will benefit them personally. | |
From: report of John Rawls (A Theory of Justice [1972]) by Bernard Williams - Ethics and the Limits of Philosophy Ch.5 | |
A reaction: The essence of modern Kantian contractualism. It is an appealing principle for building a rational world, but I hear Nietzsche turning in his grave. |
21051 | Check your rationality by thinking of your opinion pronounced by the supreme court [Rawls] |
Full Idea: To check whether we are following public reason we might ask: how would our argument strike us presented in the form of a supreme court opinion? | |
From: John Rawls (Political Liberalism [1993], p.254), quoted by Michael J. Sandel - Justice: What's the right thing to do? 10 | |
A reaction: A very nice practical implementation of Kantian universalisability. How would your opinion sound if it were written into a constitution? |
3279 | Utilitarianism inappropriately scales up the individual willingness to make sacrifices [Rawls, by Nagel] |
Full Idea: Rawls claims that utilitarianism applies to the problem of many interests a method appropriate for one individual. A single person may accept disadvantages in exchange for benefits, but in society other people get the benefits. | |
From: report of John Rawls (A Theory of Justice [1972], p.74,104) by Thomas Nagel - Equality §7 |
22406 | The maximisation of happiness must be done fairly [Rawls, by Smart] |
Full Idea: Rawls has suggested that we should maximise the general happiness only if we do so in a fair way. | |
From: report of John Rawls (Justice as fairness: Political not Metaphysical [1958]) by J.J.C. Smart - Outline of a System of Utilitarianism 6 | |
A reaction: Rawls is usually seen as an opponent of utilitarianism, but if we allow a few supplementary rules we can improve the theory. After all, it has a meta-rule that 'everybody counts as one'. What other supplementary values can there be? Honesty? |
21898 | For existentialists the present is empty without the pull of the future and weight of the past [May] |
Full Idea: For the existential view of lived time, the present would be empty if it were not for the pull of the future and the weight of the past that give it its character. | |
From: Todd May (Gilles Deleuze [2006], 2.05) | |
A reaction: Bergson seems to be important in developing this idea, though I suspect that Kierkegaard is a source. |
21137 | Rawls rejected cosmopolitanism because it doesn't respect the autonomy of 'peoples' [Rawls, by Shorten] |
Full Idea: Rawls rejected the cosmopolitan extension of his theory because he thought it failed to respect the political autonomy of 'peoples', which was his term of art for societies or political communities. | |
From: report of John Rawls (The Law of Peoples [1999], p.115-8) by Andrew Shorten - Contemporary Political Theory 09 | |
A reaction: Interesting that you might well start with the concept of 'a people', prior to some sort of social contract, but end up with rather alarming conflicts or indifference between rival peoples. Why should my people help in the famine next door? |
3280 | Why does the rational agreement of the 'Original Position' in Rawls make it right? [Nagel on Rawls] |
Full Idea: Why does what it is rational to agree to in Rawls' 'Original Position' determine what is right? | |
From: comment on John Rawls (A Theory of Justice [1972]) by Thomas Nagel - Equality §7 |
20552 | The original position models the idea that citizens start as free and equal [Rawls, by Swift] |
Full Idea: The original position is presented by Rawls as modelling the sense in which citizens are to be understood as free and equal. | |
From: report of John Rawls (A Theory of Justice [1972]) by Adam Swift - Political Philosophy (3rd ed) 3 'Strikes' | |
A reaction: In other words, Rawls's philosophy is not a demonstration of why we should be liberals, but a guidebook for how liberals should go about organising society. |
18636 | Choose justice principles in ignorance of your own social situation [Rawls] |
Full Idea: The principles of justice are chosen behind a veil of ignorance. ...Since all are similarly situated and no one is able to design principles to favor his particular condition, the principles of justice are the rest of a fair agreement or bargain. | |
From: John Rawls (A Theory of Justice [1972], §03) | |
A reaction: A famous idea. It tries to impose a Kantian impartiality onto the assessment of political principles. It is a beautifully simple idea, and saying that such impartiality never occurs is no objection to it. Think of a planet far far away. |
18631 | All desirable social features should be equal, unless inequality favours the disadvantaged [Rawls] |
Full Idea: All social primary goods - liberty and opportunity, income and wealth, and the bases of self-respect - are to be distributed equally unless an unequal distribution of any or all of these goods is to the advantage of the least favoured. | |
From: John Rawls (A Theory of Justice [1972], §46) | |
A reaction: In the wholehearted capitalism of the 21st century this sounds like cloud-cuckoo land. As an 'initial position' (just as in the 'Republic') the clean slate brings out some interesting principles. Actual politics takes vested interests as axiomatic. |
21119 | Power is only legitimate if it is reasonable for free equal citizens to endorse the constitution [Rawls] |
Full Idea: Exercise of political power is fully proper only when it is exercised in accordance with a constitution the essentials of which all citizens as free and equal may reasonably be expected to endorse in light of principles and ideals acceptable to reason. | |
From: John Rawls (Political Liberalism [1993], p.217), quoted by Andrew Shorten - Contemporary Political Theory 02 | |
A reaction: This is not the actual endorsement of Rousseau, or the tacit endorsement of Locke (by living there), but adds a Kantian appeal to a rational consensus, on which rational people should converge. Very Enlightenment. 'Hypothetical consent'. |
20538 | Utilitarians lump persons together; Rawls somewhat separates them; Nozick wholly separates them [Swift on Rawls] |
Full Idea: Rawls objects to utilitarianism because it fails to take seriously the separateness of persons (because there is no overall person to enjoy the overall happiness). But Nozick thinks Rawls does not take the separateness of persons seriously enough. | |
From: comment on John Rawls (A Theory of Justice [1972]) by Adam Swift - Political Philosophy (3rd ed) 1 'Nozick' | |
A reaction: In this sense, Nozick seems to fit our picture of a liberal more closely than Rawls does. I think they both exaggerate the separateness of persons, based on a false concept of human nature. |
21905 | Liberal theory starts from the governed, not from the governor [May] |
Full Idea: For liberal theory, it is the individual to be governed, not the governor, who is the starting point. | |
From: Todd May (Gilles Deleuze [2006], 4.02) | |
A reaction: I'm inclined to see this as the single-handed achievement of Thomas Hobbes, who starts from the need of citizens to secure their contracts. Plato's society starts from entrepreneurs, but their need for a ruler seems a priori. |
9277 | Rawls's account of justice relies on conventional fairness, avoiding all moral controversy [Gray on Rawls] |
Full Idea: Rawls's account of justice works only with widely accepted intuitions of fairness and relies at no point on controversial positions in ethics. The fruit of this modesty is a pious commentary on conventional moral beliefs. | |
From: comment on John Rawls (A Theory of Justice [1972]) by John Gray - Straw Dogs 3.6 | |
A reaction: Presumably this is the thought which provoked Nozick to lob his grenade on the subject. It resembles the charges of Schopenhauer and Nietzsche against Kant, that he was just dressing up conventional morality. Are 'controversial' ethics good? |
23420 | In a pluralist society we can't expect a community united around one conception of the good [Rawls] |
Full Idea: The fact of pluralism means that the hope of political community must be abandoned, if by such a community we mean a political society united in affirming a general and comprehensive conception of the good. | |
From: John Rawls (The Idea of Overlapping Consensus [1987]), quoted by Will Kymlicka - Community 'legitimacy' | |
A reaction: A moderate pluralism might be manageable, but strong, diverse and dogmatic beliefs among sub-groups probably make it impossible. |
20527 | Liberty Principle: everyone has an equal right to liberties, if compatible with others' liberties [Rawls] |
Full Idea: First Principle [Liberty]: Each person is to have an equal right to the most extensive total system of equal basic liberties compatible with a similar system of liberty for all. | |
From: John Rawls (A Theory of Justice [1972], 46) | |
A reaction: This is the result of consensus after the initial ignorant position of assessment. It is characteristic of liberalism. I'm struggling to think of a disagreement. |
21018 | The social contract has problems with future generations, national boundaries, disabilities and animals [Rawls, by Nussbaum] |
Full Idea: Rawls saw four difficulties for justice in the social contract approach: future generations; justice across national boundaries; fair treatment of people with disabilities; and moral issues involving non-human animals. | |
From: report of John Rawls (A Theory of Justice [1972]) by Martha Nussbaum - Creating Capabilities 4 | |
A reaction: These are all classic examples of groups who do not have sufficient power to negotiate contracts. |
21041 | Justice concerns not natural distributions, or our born location, but what we do about them [Rawls] |
Full Idea: The natural distribution is neither just nor unjust; nor is it unjust that persons are born into society at some particular position. These are simply natural facts. What is just and unjust is the way that institutions deal with these facts. | |
From: John Rawls (A Theory of Justice [1972], 17) | |
A reaction: Lovely quotation. There is no point in railing against the given, and that includes what is given by history, as well as what is given by nature. It comes down to intervening, in history and in nature. How much intervention will individuals tolerate? |
23583 | If an aggression is unjust, the constraints on how it is fought are much stricter [Rawls] |
Full Idea: When a country's right to war is questionable and uncertain, the constraints on the means it can use are all the more severe. | |
From: John Rawls (A Theory of Justice [1972], p.379), quoted by Michael Walzer - Just and Unjust Wars 14 | |
A reaction: This is Rawls opposing the idea that combatants are moral equals. The restraints are, of course, moral. In practice aggressors are usually the worst behaved. |
17381 | Phylogenetics involves history, and cladism rests species on splits in lineage [Dupré] |
Full Idea: The phylogenetic conception of classification reflects the facts of evolutionary history. Cladism insists that every taxonomic distinction should reflect an evolutionary event of lineage bifurcation. | |
From: John Dupré (The Disorder of Things [1993], 1) | |
A reaction: Devitt attacks cladism nicely. It rules out species change without bifurcation, and it insists on species change even in a line which remains unchanged after a split. |
17385 | Kinds don't do anything (including evolve) because they are abstract [Dupré] |
Full Idea: A kind, being an abstract object, cannot do anything, including evolve. | |
From: John Dupré (The Disorder of Things [1993], 2) | |
A reaction: Maybe. We might have an extensional view of the kind, so that 'gold' is the set of extant gold atoms. But possible gold atoms are also gold, and defunct ones too. Virtually every word in English is abtract if you think about it long enough. |
17375 | Natural kinds are decided entirely by the intentions of our classification [Dupré] |
Full Idea: The question of which natural kind a thing belongs to ....can be answered only in relation to some specification of the goal underlying the intent to classify the object. | |
From: John Dupré (The Disorder of Things [1993], Intro) | |
A reaction: I don't think I believe this. The situation is complex, and our intents are relevant, but to find an intent which no longer classifies tigers into the same category is wilful silliness. |
17379 | Borders between species are much less clear in vegetables than among animals [Dupré] |
Full Idea: The richest source of illustrations is the vegetable kingdom, where specific differences tend to be much less clear than among animals, and considerable developmental plasticity is the rule. | |
From: John Dupré (The Disorder of Things [1993], 1) | |
A reaction: Nice. Just as the idea that laws of nature are mathematical suits physics, but founders on biology, so natural kinds founder in an area of biology to which we pay less attention. He cites prickly pears and lilies. I'm thinking oranges, satsumas etc. |
17384 | Even atoms of an element differ, in the energy levels of their electrons [Dupré] |
Full Idea: Even if we claim that it is really isotopes not atoms that are the natural kinds (thus divorcing chemistry from ordinary language), atoms are said to differ with respect to such features as energy levels of the electrons. | |
From: John Dupré (The Disorder of Things [1993], 2) | |
A reaction: So we can't just pick out the features of one atom, and say that is the essence. Essence always involves some selection. I say the essence arises from the explanation of the atom's behaviour. |
17387 | Ecologists favour classifying by niche, even though that can clash with genealogy [Dupré] |
Full Idea: To the extent that the occupants of a particular niche do not coincide with the members of a particular genealogical line, a possibility widely acknowledged to occur, ecologists must favour a method of classification lacking genealogical grounding. | |
From: John Dupré (The Disorder of Things [1993], 2) | |
A reaction: Zoo keepers probably classify by cages, or which zoo owns what, but that doesn't mean that they reject genealogy. Don't assume ecologists are rejecting any underlying classification that differs from theirs. Compare classification by economists. |
17382 | Cooks, unlike scientists, distinguish garlic from onions [Dupré] |
Full Idea: It would be a severe culinary misfortune if no distinction were drawn between garlic and onions, a distinction that is not reflected in scientific taxonomy. | |
From: John Dupré (The Disorder of Things [1993], 1) | |
A reaction: Not every persuasive. We distinguish some cows from others because they taste better, but no one thinks that is a serious way in which to classify cows. |
17380 | Wales may count as fish [Dupré] |
Full Idea: The claim that whales are not fish is a debatable one | |
From: John Dupré (The Disorder of Things [1993], 1) | |
A reaction: A very nice challenge to an almost unquestioned orthodoxy. |
17383 | Species are the lowest-level classification in biology [Dupré] |
Full Idea: Species are, by definition, the lowest-level classificatory unit, or basal taxonomic unit, for biological organisms. | |
From: John Dupré (The Disorder of Things [1993], 2) | |
A reaction: I think this is the 'infima species' for Aristotelians. What about 'male' and 'female' in each species? |
17386 | The theory of evolution is mainly about species [Dupré] |
Full Idea: Species are what the theory of evolution is centrally about. | |
From: John Dupré (The Disorder of Things [1993], 2) |
