11115 | 'All horses' either picks out the horses, or the things which are horses [Jubien] |
Full Idea: Two ways to see 'all horses are animals' are as picking out all the horses (so that it is a 'horse-quantifier'), ..or as ranging over lots of things in addition to horses, with 'horses' then restricting the things to those that satisfy 'is a horse'. | |
From: Michael Jubien (Analyzing Modality [2007], 2) | |
A reaction: Jubien says this gives you two different metaphysical views, of a world of horses etc., or a world of things which 'are horses'. I vote for the first one, as the second seems to invoke an implausible categorical property ('being a horse'). Cf Idea 11116. |
8780 | Attributes are functions, not objects; this distinguishes 'square of 2' from 'double of 2' [Geach] |
Full Idea: Attributes should not be thought of as identifiable objects. It is better to follow Frege and compare them to mathematical functions. 'Square of' and 'double of' x are distinct functions, even though they are not distinguishable in thought when x is 2. | |
From: Peter Geach (Mental Acts: their content and their objects [1957], §11) | |
A reaction: Attributes are features of the world, of which animals are well aware, and the mathematical model is dubious when dealing with physical properties. The route to arriving at 2 is not the same concept as 2. There are many roads to Rome. |
11116 | Being a physical object is our most fundamental category [Jubien] |
Full Idea: Being a physical object (as opposed to being a horse or a statue) really is our most fundamental category for dealing with the external world. | |
From: Michael Jubien (Analyzing Modality [2007], 2) | |
A reaction: This raises the interesting question of why any categories should be considered to be more 'fundamental' than others. I can only think that we perceive something to be an object fractionally before we (usually) manage to identify it. |
11117 | Haecceities implausibly have no qualities [Jubien] |
Full Idea: Properties of 'being such and such specific entity' are often called 'haecceities', but this term carries the connotation of non-qualitativeness which I don't favour. | |
From: Michael Jubien (Analyzing Modality [2007], 2) | |
A reaction: The way he defines it makes it sound as if it was a category, but I take it to be more like a bare individual essence. If it has not qualities then it has no causal powers, so there could be no evidence for its existence. |
11910 | Being 'the same' is meaningless, unless we specify 'the same X' [Geach] |
Full Idea: "The same" is a fragmentary expression, and has no significance unless we say or mean "the same X", where X represents a general term. ...There is no such thing as being just 'the same'. | |
From: Peter Geach (Mental Acts: their content and their objects [1957], §16) | |
A reaction: Geach seems oddly unaware of the perfect identity of Hespherus with Phosphorus. His critics don't spot that he was concerned with identity over time (of 'the same man', who ages). Perry's critique emphasises the type/token distinction. |
11119 | De re necessity is just de dicto necessity about object-essences [Jubien] |
Full Idea: I suggest that the de re is to be analyzed in terms of the de dicto. ...We have a case of modality de re when (and only when) the appropriate property in the de dicto formulation is an object-essence. | |
From: Michael Jubien (Analyzing Modality [2007], 5) |
11118 | Modal propositions transcend the concrete, but not the actual [Jubien] |
Full Idea: Where modal propositions may once have seemed to transcend the actual, they now seem only to transcend the concrete. | |
From: Michael Jubien (Analyzing Modality [2007], 4) | |
A reaction: This is because Jubien has defended a form of platonism. Personally I take modal propositions to be perceptible in the concrete world, by recognising the processes involved, not the mere static stuff. |
11108 | Your properties, not some other world, decide your possibilities [Jubien] |
Full Idea: The possibility of your having been a playwright has nothing to do with how people are on other planets, whether in our own or in some other realm. It is only to do with you and the relevant property. | |
From: Michael Jubien (Analyzing Modality [2007], 1) | |
A reaction: I'm inclined to think that this simple point is conclusive disproof of possible worlds as an explanation of modality (apart from Jubien's other nice points). What we need to understand are modal properties, not other worlds. |
11111 | Modal truths are facts about parts of this world, not about remote maximal entities [Jubien] |
Full Idea: Typical modal truths are just facts about our world, and generally facts about very small parts of it, not facts about some infinitude of complex, maximal entities. | |
From: Michael Jubien (Analyzing Modality [2007], 1) | |
A reaction: I think we should embrace this simple fact immediately, and drop all this nonsense about possible worlds, even if they are useful for the semantics of modal logic. |
11109 | If other worlds exist, then they are scattered parts of the actual world [Jubien] |
Full Idea: Any other realms that happened to exist would just be scattered parts of the actual world, not entire worlds at all. It would just happen that physical reality was fragmented in this remarkable but modally inconsequential way. | |
From: Michael Jubien (Analyzing Modality [2007], 1) | |
A reaction: This is aimed explicitly at Lewis's modal realism, and strikes me as correct. Jubien's key point here is that they are irrelevant to modality, just as foreign countries are irrelevant to the modality of this one. |
11106 | If all possible worlds just happened to include stars, their existence would be necessary [Jubien] |
Full Idea: If all of the possible worlds happened to include stars, how plausible is it to think that if this is how things really are, then we've just been wrong to regard the existence of stars as contingent? | |
From: Michael Jubien (Analyzing Modality [2007], 1) |
11112 | Possible worlds just give parallel contingencies, with no explanation at all of necessity [Jubien] |
Full Idea: In the world theory, what passes for 'necessity' is just a bunch of parallel 'contingencies'. The theory provides no basis for understanding why these contingencies repeat unremittingly across the board (while others do not). | |
From: Michael Jubien (Analyzing Modality [2007], 1) |
11113 | Worlds don't explain necessity; we use necessity to decide on possible worlds [Jubien] |
Full Idea: The suspicion is that the necessity doesn't arise from how worlds are, but rather that the worlds are taken to be as they are in order to capture the intuitive necessity. | |
From: Michael Jubien (Analyzing Modality [2007], 1) | |
A reaction: It has always seemed to me rather glaring that you need a prior notion of 'possible' before you can start to talk about 'possible worlds', but I have always been too timid to disagree with the combination of Saul Kripke and David Lewis. Thank you, Jubien! |
11105 | We have no idea how many 'possible worlds' there might be [Jubien] |
Full Idea: As soon as we start talking about 'possible world', we beg the question of their relevance to our prior notion of possibility. For all we know, there are just two such realms, or twenty-seven, or uncountably many, or even set-many. | |
From: Michael Jubien (Analyzing Modality [2007], 1) |
11107 | If there are no other possible worlds, do we then exist necessarily? [Jubien] |
Full Idea: Suppose there happen to be no other concrete realms. Would we happily accept the consequence that we exist necessarily? | |
From: Michael Jubien (Analyzing Modality [2007], 1) |
11110 | We mustn't confuse a similar person with the same person [Jubien] |
Full Idea: If someone similar to Humphrey won the election, that nicely establishes the possibility of someone's winning who is similar to Humphrey. But we mustn't confuse this possibility with the intuitively different possibility of Humphrey himself winning. | |
From: Michael Jubien (Analyzing Modality [2007], 1) |
5303 | For the proletariate, law, morality and religion are just expressions of bourgeois interests [Marx/Engels] |
Full Idea: Law, morality, religion are to the proletarian so many bourgeois prejudices, behind which lurk in ambush just as many bourgeois interests. | |
From: K Marx / F Engels (The Communist Manifesto [1848], §1) | |
A reaction: This Marxist idea has been the main driving force in spreading relativist views through modern culture. There is a lot of truth here, but philosophy is plausibly the search for truths which both the bourgeois and the proletarian will accept. |
8775 | A big flea is a small animal, so 'big' and 'small' cannot be acquired by abstraction [Geach] |
Full Idea: A big flea or rat is a small animal, and a small elephant is a big animal, so there can be no question of ignoring the kind of thing to which 'big' or 'small' is referred and forming those concepts by abstraction. | |
From: Peter Geach (Mental Acts: their content and their objects [1957], §9) | |
A reaction: Geach is attacking a caricature of the theory. Abstraction is a neat mental trick which has developed in stages, from big rats relative to us, to big relative to other rats, to the concept of 'relative' (Idea 8776!), to the concept of 'relative bigness'. |
8776 | We cannot learn relations by abstraction, because their converse must be learned too [Geach] |
Full Idea: Abstractionists are unaware of the difficulty with relations - that they neither exist nor can be observed apart from the converse relation, the two being indivisible, as in grasping 'to the left of' and 'to the right of'. | |
From: Peter Geach (Mental Acts: their content and their objects [1957], §9) | |
A reaction: It is hard to see how a rival account such as platonism could help. It seems obvious to me that 'right' and 'left' would be quite meaningless without some experience of things in space, including an orientation to them. |
2567 | You can't define real mental states in terms of behaviour that never happens [Geach] |
Full Idea: We can't take a statement that two men, whose overt behaviour was not actually different, were in different states of mind as being really a statement that the behaviour of one man would have been different in hypothetical circumstances that never arose. | |
From: Peter Geach (Mental Acts: their content and their objects [1957], §3) | |
A reaction: This is the whole problem with trying to define the mind as dispositions. The same might be said of properties, since some properties are active, but others are mere potential or disposition. Hence 'process' looks to me the most promising word for mind. |
2568 | Beliefs aren't tied to particular behaviours [Geach] |
Full Idea: Is there any behaviour characteristic of a given belief? | |
From: Peter Geach (Mental Acts: their content and their objects [1957], §4) | |
A reaction: Well, yes. Belief that a dog is about to bite you. Belief that this nice food is yours, and you are hungry. But he has a good point. He is pointing out that the mental state is a very different thing from the 'disposition' to behave in a certain way. |
8781 | The mind does not lift concepts from experience; it creates them, and then applies them [Geach] |
Full Idea: Having a concept is not recognizing a feature of experience; the mind makes concepts. We then fit our concepts to experience. | |
From: Peter Geach (Mental Acts: their content and their objects [1957], §11) | |
A reaction: This seems to imply that we create concepts ex nihilo, which is a rather worse theory than saying that we abstract them from multiple (and multi-level) experiences. That minds create concepts is a truism. How do we do it? |
8769 | If someone has aphasia but can still play chess, they clearly have concepts [Geach] |
Full Idea: If a man struck with aphasia can still play bridge or chess, I certainly wish to say he still has the concepts involved in the game, although he can no longer exercise them verbally. | |
From: Peter Geach (Mental Acts: their content and their objects [1957], §5) | |
A reaction: Geach proceeds thereafter to concentrate on language, but this caveat is crucial. To suggest that concepts are entirely verbal has always struck me as ridiculous, and an insult to our inarticulate mammalian cousins. |
8770 | 'Abstractionism' is acquiring a concept by picking out one experience amongst a group [Geach] |
Full Idea: I call 'abstractionism' the doctrine that a concept is acquired by a process of singling out in attention some one feature given in direct experience - abstracting it - and ignoring the other features simultaneously given - abstracting from them. | |
From: Peter Geach (Mental Acts: their content and their objects [1957], §6) | |
A reaction: Locke seems to be the best known ancestor of this view, and Geach launches a vigorous attack against it. However, contemporary philosophers still refer to the process, and I think Geach should be crushed and this theory revived. |
8771 | 'Or' and 'not' are not to be found in the sensible world, or even in the world of inner experience [Geach] |
Full Idea: Nowhere in the sensible world could you find anything to be suitably labelled 'or' or 'not'. So the abstractionist appeals to an 'inner sense', or hesitation for 'or', and of frustration or inhibition for 'not'. Personally I see a threat in 'or else'! | |
From: Peter Geach (Mental Acts: their content and their objects [1957], §7) | |
A reaction: This is a key argument of Geach's against abstractionism. As a logician he prefers to discuss connectives rather than, say, colours. I think they might be meta-abstractions, which you create internally once you have picked up the knack. |
8772 | We can't acquire number-concepts by extracting the number from the things being counted [Geach] |
Full Idea: The number-concepts just cannot be got by concentrating on the number and abstracting from the kind of things being counted. | |
From: Peter Geach (Mental Acts: their content and their objects [1957], §8) | |
A reaction: This point is from Frege - that if you 'abstract away' everything apart from the number, you are simply left with nothing in experience. The objection might, I think, be met by viewing it as second-order abstraction, perhaps getting to a pattern first. |
8773 | Abstractionists can't explain counting, because it must precede experience of objects [Geach] |
Full Idea: The way counting is learned is wholly contrary to abstractionist preconceptions, because the series of numerals has to be learned before it can be applied. | |
From: Peter Geach (Mental Acts: their content and their objects [1957], §8) | |
A reaction: You might learn to parrot the names of numbers, but you could hardly know what they meant if you couldn't count anything. See Idea 3907. I would have thought that individuating objects must logically and pedagogically precede counting. |
8774 | The numbers don't exist in nature, so they cannot have been abstracted from there into our languages [Geach] |
Full Idea: The pattern of the numeral series that is grasped by a child exists nowhere in nature outside human languages, so the human race cannot possibly have discerned this pattern by abstracting it from some natural context. | |
From: Peter Geach (Mental Acts: their content and their objects [1957], §8) | |
A reaction: This is a spectacular non sequitur, which begs the question. Abstractionists precisely claim that the process of abstraction brings numerals into human language from the natural context. Structuralism is an attempt to explain the process. |
8778 | Blind people can use colour words like 'red' perfectly intelligently [Geach] |
Full Idea: It is not true that men born blind can form no colour-concepts; a man born blind can use the word 'red' with a considerable measure of intelligence; he can show a practical grasp of the logic of the word. | |
From: Peter Geach (Mental Acts: their content and their objects [1957], §10) | |
A reaction: Weak. It is obvious that they pick up the word 'red' from the usage of sighted people, and the usage of the word doesn't guarantee a grasp of the concept, as when non-mathematicians refer to 'calculus'. Compare Idea 7377 and Idea 7866. |
8777 | If 'black' and 'cat' can be used in the absence of such objects, how can such usage be abstracted? [Geach] |
Full Idea: Since we can use the terms 'black' and 'cat' in situations not including any black object or any cat, how could this part of the use be got by abstraction? | |
From: Peter Geach (Mental Acts: their content and their objects [1957], §10) | |
A reaction: [He is attacking H.H. Price] It doesn't seem a huge psychological leap to apply the word 'cat' when we remember a cat, and once it is in the mind we can play games with our abstractions. Cats are smaller than dogs. |
8779 | We can form two different abstract concepts that apply to a single unified experience [Geach] |
Full Idea: It is impossible to form the concept of 'chromatic colour' by discriminative attention to a feature given in my visual experience. In seeing a red window-pane, I do not have two sensations, one of redness and one of chromatic colour. | |
From: Peter Geach (Mental Acts: their content and their objects [1957], §10) | |
A reaction: Again Geach begs the question, because abstractionists claim that you can focus on two different 'aspects' of the one experience, as that it is a 'window', or it is 'red', or it is not a wall, or it is not monochrome. |
21998 | Bourgeois interests create our morality, law and religion [Marx/Engels] |
Full Idea: Morality, law and religion are bourgeois prejudices, behind which lurk in ambush just as many bourgeois interests. | |
From: K Marx / F Engels (The Communist Manifesto [1848], p.230), quoted by Peter Singer - Marx 9 | |
A reaction: The obvious question is whether this creation of values is conscious or unconscious. Personally I believe in conspiracies. Some cynical conversations go on behind the scenes, of which historians will never hear. |
5302 | Modern governments are just bourgeois management committees [Marx/Engels] |
Full Idea: The executive of the modern State is but a committee for managing the common affairs of the whole bourgeoisie. | |
From: K Marx / F Engels (The Communist Manifesto [1848], §1) | |
A reaction: In Britain the Labour Party and the Trade Unions have appeared since 1848, but bourgeoisie control of the media has pushed us a long way back towards Marx's time. Government will always be someone's management committee. |
5304 | Communism aims to abolish not all property, but bourgeois property [Marx/Engels] |
Full Idea: The distinguishing feature of Communism is not the abolition of property generally, but the abolition of bourgeois property. | |
From: K Marx / F Engels (The Communist Manifesto [1848], §2) | |
A reaction: This is a sinister remark which has led to huge numbers of murders in the Soviet Union and China. People resent having their property 'abolished', especially if they have worked hard for it. But most of our wealth is owned by about 2% of our people. |
5307 | Many of the bourgeois rights grievances are a form of self-defence [Marx/Engels] |
Full Idea: A part of the bourgeoisie is desirous of redressing social grievances, in order to secure the continued existence of bourgeois society. | |
From: K Marx / F Engels (The Communist Manifesto [1848], §3.II) | |
A reaction: …so don't try being nice to us. No TRUE bourgeois would actually want to help the proletariate… Nevertheless, he is probably largely right. Do we want the poor to suffer? No. Do we want them to be as rich as us? No! |
5306 | The free development of each should be the condition for the free development of all [Marx/Engels] |
Full Idea: In a communist society we shall have an association, in which the free development of each is the condition for the free development of all. | |
From: K Marx / F Engels (The Communist Manifesto [1848], §2) | |
A reaction: This ringing slogan is remarkably close to John Stuart Mill's defence of liberalism, where liberty is an absolute, as long as it avoids the liberty of others. Personally I think freedom is marginal in political philosophy, like food and shelter. |
5305 | Communists want to rescue education from the ruling class [Marx/Engels] |
Full Idea: Communists seek to rescue education from the influence of the ruling class. | |
From: K Marx / F Engels (The Communist Manifesto [1848], §2) | |
A reaction: Someone has to control education, and I would personally prefer it if the controllers were well educated themselves. Neutral education is an idle dream. We must educate for democracy, if we really want democracy. |
5301 | The history of all existing society is the history of class struggles [Marx/Engels] |
Full Idea: The history of all existing society is the history of class struggles. | |
From: K Marx / F Engels (The Communist Manifesto [1848], §1) | |
A reaction: This seems to make, say, the English Peasants' Revolt of 1481 crucial, and the building of Lincoln Cathedral fairly minor. Where does the advent of the telephone figure? Etc. Still, we must concede his point. Most medieval history is about power. |
