| 12865 | Analytic philosophers may prefer formal systems because natural language is such mess [Simons] |
| Full Idea: The untidiness of natural language in its use of 'part' is perhaps one of the chief reasons why mereolologists have preferred to investigate formal systems with nice algebraic properties rather than get out and mix it with reality in all its messiness. | |
| From: Peter Simons (Parts [1987], 6.4) | |
| A reaction: [See Idea 12864 for the uses of 'part'] I am in the unhappy (and probably doomed) position of wanting to avoid both approaches. I try to operate as if the English language were transparent and we can just discuss the world. Very naïve. |
| 2474 | It seems likely that analysis of concepts is impossible, but justification can survive without it [Fodor] |
| Full Idea: Lots of philosophers fear that if concepts don't have analyses, justification breaks down. My own guess is that concepts don't have analyses and that justification will survive all the same. | |
| From: Jerry A. Fodor (In a Critical Condition [2000], Ch. 3 n2) |
| 2481 | Despite all the efforts of philosophers, nothing can ever be reduced to anything [Fodor] |
| Full Idea: The general truth is that nothing ever reduces to anything, however hard philosophers may try. | |
| From: Jerry A. Fodor (In a Critical Condition [2000], Ch. 6) |
| 2505 | Turing invented the idea of mechanical rationality (just based on syntax) [Fodor] |
| Full Idea: The most important thing that has happened in cognitive science was Turing's invention of the notion of mechanical rationality (because some inferences are rational in virtue of the syntax of their sentences). | |
| From: Jerry A. Fodor (In a Critical Condition [2000], Ch.17) |
| 2470 | Transcendental arguments move from knowing Q to knowing P because it depends on Q [Fodor] |
| Full Idea: Transcendental arguments ran: "If it weren't that P, we couldn't know (now 'say' or 'think' or 'judge') that Q; and we do know (now…) that Q; therefore P". Old and new arguments tend to be equally unconvincing, because of their empiricist preconceptions. | |
| From: Jerry A. Fodor (In a Critical Condition [2000], Ch. 3) |
| 12815 | Classical mereology doesn't apply well to the objects around us [Simons] |
| Full Idea: The most fundamental criticism of classical mereology is that the theory is not applicable to most of the objects around us, and is accordingly of little use as a formal reconstruction of the concepts of part and whole which we actually employ. | |
| From: Peter Simons (Parts [1987], Intro) | |
| A reaction: This sounds splendidly dismissive, but one might compare it with possible worlds semantics for modal logic, which most people take with a pinch of salt as an actual commitment, but find wonderfully clarifying in modal reasoning. |
| 12832 | Complement: the rest of the Universe apart from some individual, written x-bar [Simons] |
| Full Idea: The 'complement' of each individual in mereology is the rest of the Universe outside it, that is U - x, but written as x-bar [x with a horizontal bar above it]. | |
| From: Peter Simons (Parts [1987], 1.1.10) | |
| A reaction: [Don't have a font for x-bar] See Idea 12831 for the 'Universe'. Simons suggest that the interest of this term is mainly historical and algebraic. |
| 12834 | Criticisms of mereology: parts? transitivity? sums? identity? four-dimensional? [Simons] |
| Full Idea: Main criticisms of mereology: we don't mean 'part' as improper; transitivity of 'part' is sometimes not transitive; no guarantee that there are 'sums'; the identity criteria for individuals are false; we are forced into materialistic four-dimensionalism. | |
| From: Peter Simons (Parts [1987], 3.2) | |
| A reaction: [Compressed summary; for four-dimensionalism see under 'Identity over Time'] Simons says these are in ascending order of importance. |
| 12819 | A 'part' has different meanings for individuals, classes, and masses [Simons] |
| Full Idea: It emerges that 'part', like other formal concepts, is not univocal, but has analogous meanings according to whether we talk of individuals, classes, or masses. | |
| From: Peter Simons (Parts [1987], Intro) | |
| A reaction: He suggests that unrestricted sums are appropriate for the last two, but not for individuals. There must be something univocal about the word - some awareness of a possible whole or larger entity to which the thing could belong. |
| 12822 | Proper or improper part: x < y, 'x is (a) part of y' [Simons] |
| Full Idea: A 'proper or improper part' is expressed by 'x < y', read as 'x is (a) part of y'. The relatively minor deviation from normal usage (of including an improper part, i.e. the whole thing) is warranted by its algebraical convenience. | |
| From: Peter Simons (Parts [1987], 1.1.02) | |
| A reaction: Including an improper part (i.e. the whole thing) is not, Simons points out, uncontroversial, because the part being 'equal' to the whole is read as being 'identical' to the whole, which Simons is unwilling to accept. |
| 12824 | Disjoint: two individuals are disjoint iff they do not overlap, written 'x | y' [Simons] |
| Full Idea: Two individuals are 'disjoint' mereologically if and only if they do not overlap, expressed by 'x | y', read as 'x is disjoint from y'. Disjointedness is symmetric. | |
| From: Peter Simons (Parts [1987], 1.1.04) |
| 12827 | Difference: the difference of individuals is the remainder of an overlap, written 'x - y' [Simons] |
| Full Idea: The 'difference' of two individuals is the largest individual contained in x which has no part in common with y, expressed by 'x - y', read as 'the difference of x and y'. | |
| From: Peter Simons (Parts [1987], 1.1.07) |
| 12823 | Overlap: two parts overlap iff they have a part in common, expressed as 'x o y' [Simons] |
| Full Idea: Two parts 'overlap' mereologically if and only if they have a part in common, expressed by 'x o y', read as 'x overlaps y'. Overlapping is reflexive and symmetric but not transitive. | |
| From: Peter Simons (Parts [1987], 1.1.03) | |
| A reaction: Simons points out that we are uncomfortable with overlapping (as in overlapping national boundaries), because we seem to like conceptual boundaries. We avoid overlap even in ordering primary colour terms, by having a no-man's-land. |
| 12825 | Product: the product of two individuals is the sum of all of their overlaps, written 'x · y' [Simons] |
| Full Idea: For two overlapping individuals their 'product' is the individual which is part of both and such that any common part of both is part of it, expressed by 'x · y', read as 'the product of x and y'. | |
| From: Peter Simons (Parts [1987], 1.1.05) | |
| A reaction: That is, the 'product' is the sum of any common parts between two individuals. In set theory all sets intersect at the null set, but mereology usually avoids the 'null individual'. |
| 12826 | Sum: the sum of individuals is what is overlapped if either of them are, written 'x + y' [Simons] |
| Full Idea: The 'sum' of two individuals is that individual which something overlaps iff it overlaps at least one of x and y, expressed by 'x + y', read as 'the sum of x and y'. It is central to classical extensional mereologies that any two individuals have a sum. | |
| From: Peter Simons (Parts [1987], 1.1.06) | |
| A reaction: This rather technical definition (defining an individual by the possibility of it being overlapped) does not always coincide with the smallest individual containing them both. |
| 12828 | General sum: the sum of objects satisfying some predicate, written σx(Fx) [Simons] |
| Full Idea: The 'general sum' of all objects satisfying a certain predicate is denoted by a variable-binding operator, expressed by 'σx(Fx)', read as 'the sum of objects satisfying F'. | |
| From: Peter Simons (Parts [1987], 1.1.08) | |
| A reaction: This, it seems, is introduced to restrict some infinite classes which aspire to be sums. |
| 12829 | General product: the nucleus of all objects satisfying a predicate, written πx(Fx) [Simons] |
| Full Idea: The 'general product' or 'nucleus' of all objects satisfying a certain predicate is denoted by a variable-binding operator, expressed by 'πx(Fx)', read as 'the product of objects satisfying F'. | |
| From: Peter Simons (Parts [1987], 1.1.08) | |
| A reaction: See Idea 12825 for 'product'. 'Nucleus' is a helpful word here. Thought: is the general product a candidate for a formal definition of essence? It would be a sortal essence - roughly, what all beetles have in common, just by being beetles. |
| 12830 | Universe: the mereological sum of all objects whatever, written 'U' [Simons] |
| Full Idea: The 'Universe' in mereology is the sum of all objects whatever, a unique individual of which all individuals are part. This is denoted by 'U'. Strictly, there can be no 'empty Universe', since the Universe is not a container, but the whole filling. | |
| From: Peter Simons (Parts [1987], 1.1.09) | |
| A reaction: This, of course, contrasts with set theory, which cannot have a set of all sets. At the lower end, set theory does have a null set, while mereology has no null individual. See David Lewis on combining the two theories. |
| 12831 | Atom: an individual with no proper parts, written 'At x' [Simons] |
| Full Idea: An 'atom' in mereology is an individual with no proper parts. We shall use the expression 'At x' to mean 'x is an atom'. | |
| From: Peter Simons (Parts [1987], 1.1.11) | |
| A reaction: Note that 'part' in standard mereology includes improper parts, so every object has at least one part, namely itself. |
| 12844 | Dissective: stuff is dissective if parts of the stuff are always the stuff [Simons] |
| Full Idea: Water is said not to be 'dissective', since there are parts of any quantity of water which are not water. | |
| From: Peter Simons (Parts [1987], 4.2) | |
| A reaction: This won't seem to do for any physical matter, but presumably parts of numbers are always numbers. |
| 12813 | Two standard formalisations of part-whole theory are the Calculus of Individuals, and Mereology [Simons] |
| Full Idea: The standardly accepted formal theory of part-whole is classical extensional mereology, which is known in two logical guises, the Calculus of Individuals of Leonard and Goodman, and the Mereology of Lesniewski. | |
| From: Peter Simons (Parts [1987], Intro) | |
| A reaction: Simons catalogues several other modern attempts at axiomatisation in his chapter 2. |
| 12821 | The part-relation is transitive and asymmetric (and thus irreflexive) [Simons] |
| Full Idea: Formally, the part-relation is transitive and asymmetric (and thus irreflexive). Hence nothing is a proper part of itself, things aren't proper parts of one another, and if one is part of two which is part of three then one is part of three. | |
| From: Peter Simons (Parts [1987], 1.1.1) |
| 18847 | Each wheel is part of a car, but the four wheels are not a further part [Simons] |
| Full Idea: The four wheels of a car are parts of it (each is part of it), but there is not a fifth part consisting of the four wheels. | |
| From: Peter Simons (Parts [1987], 4.6) | |
| A reaction: This raises questions about the transitivity of parthood. If there are parts of parts of wholes, the basic parts are OK, and the whole is OK, but how can there also be an intermediate part? Try counting the parts of this whole! |
| 12816 | Classical mereology doesn't handle temporal or modal notions very well [Simons] |
| Full Idea: The underlying logic of classical extensional mereology does not have the resources to deal with temporal and modal notions such as temporary part, temporal part, essential part, or essential permanent part. | |
| From: Peter Simons (Parts [1987], Intro) | |
| A reaction: Simons tries to rectify this in the later chapters of his book, with modifications rather than extensions. Since everyone struggles with temporal and modal issues of identity, we shouldn't judge too harshly. |
| 12846 | A 'group' is a collection with a condition which constitutes their being united [Simons] |
| Full Idea: We call a 'collection' of jewels a 'group' term. Several random musicians are unlikely to be an orchestra. If they come together regularly in a room to play, such conditions are constitutive of an orchestra. | |
| From: Peter Simons (Parts [1987], 4.4) | |
| A reaction: Clearly this invites lots of borderline cases. Eleven footballers don't immediately make a team, as followers of the game know well. |
| 12848 | The same members may form two groups [Simons] |
| Full Idea: Groups may coincide in membership without being identical - extensionality goes. | |
| From: Peter Simons (Parts [1987], 4.9) | |
| A reaction: Thus an eleven-person orchestra may also constitute a football team. What if a pile of stones is an impediment to you, and useful to me? Is it then two groups? Suppose they hum while playing football? (Don't you just love philosophy?) |
| 12861 | 'The wolves' are the matter of 'the pack'; the latter is a group, with different identity conditions [Simons] |
| Full Idea: 'The wolves' is a plural term referring to just these animals, whereas 'the pack' of wolves refers to a group, and the group and plurality, while they may coincide in membership, have different identity conditions. The wolves are the matter of the pack. | |
| From: Peter Simons (Parts [1987], 6.4) | |
| A reaction: Even a cautious philosopher like Simons is ready to make bold ontological commitment to 'packs', on the basis of something called 'identity conditions'. I think it is just verbal. You can qualify 'the wolves' and 'the pack' to make them identical. |
| 12876 | Philosophy is stuck on the Fregean view that an individual is anything with a proper name [Simons] |
| Full Idea: Modern philosophy is still under the spell of Frege's view that an individual is anything that has a proper name. (Note: But not only are empty names now recognised, but some are aware of the existence of plural reference). | |
| From: Peter Simons (Parts [1987], 8.1) | |
| A reaction: Presumably every electron in the universe is an individual, and every (finite) number which has never been named has a pretty clear identity. Presumably Pegasus, John Doe, and 'the person in the kitchen' have to be accommodated. |
| 12845 | Some natural languages don't distinguish between singular and plural [Simons] |
| Full Idea: The syntactic distinction between singular and plural is not a universal feature of natural languages. Chinese manages nicely without it, and Sanskrit makes a tripartite distinction between singular, dual, and plural (more than two). | |
| From: Peter Simons (Parts [1987], 4.3) | |
| A reaction: Simons is mounting an attack on the way in which modern philosophy and logic has been mesmerised by singular terms and individuated objects. Most people seem now to agree with Simons. There is stuff, as well as plurals. |
| 12838 | Four-dimensional ontology has no change, since that needs an object, and time to pass [Simons] |
| Full Idea: In the four-dimensional ontology there may be timeless variation, but there is no change. Change consists in an object having first one property and then another contrary one. But processes all have their properties timelessly. | |
| From: Peter Simons (Parts [1987], 3.4) | |
| A reaction: Possibly Simons is begging the question here. The phenomena which are traditionally labelled as 'change' are all nicely covered in the four-D account. Change is, we might say, subsumed in the shape of the space-time 'worm'. |
| 12842 | There are real relational changes, as well as bogus 'Cambridge changes' [Simons] |
| Full Idea: It is a mistake to call bogus Cambridge changes 'relational changes', since there are real relational changes, such as the changes in the relative positions and distances of several bodies. | |
| From: Peter Simons (Parts [1987], 4.1) | |
| A reaction: I'm not sure how you distinguish the two. If we swap seats, that is a real change. If everyone moves away from where I am sitting, is that real or Cambridge? If I notice, I might be upset, but suppose I don't notice? Nothing about me changes. |
| 12841 | I don't believe in processes [Simons] |
| Full Idea: I have been unable to see that there are processes. | |
| From: Peter Simons (Parts [1987], 4.1 n4) | |
| A reaction: My problem here is that I am inclined to think of the mind as a process of the brain. The fact that a reductive account can be given of a process doesn't mean that we can deny there existence. Is there no such thing as decay, or erosion? |
| 12836 | Fans of process ontology cheat, since river-stages refer to 'rivers' [Simons] |
| Full Idea: Proponents of process ontology (except perhaps Whitehead, who is obscure) indulge in double-talk with concrete examples. It is cheating to talk of 'cat-processes', or 'bathing in river-stages'. You can't change the subject and leave the predicate alone. | |
| From: Peter Simons (Parts [1987], 3.4) | |
| A reaction: It is one thing to admit processes into one's ontology, and another to have a 'process ontology', which presumably reduces objects to processes. I suppose the interest of continuant objects is precisely the aspect of them that is above any process. |
| 12880 | Moments are things like smiles or skids, which are founded on other things [Simons] |
| Full Idea: A 'moment' is something which is founded on something else. Examples are legion: smiles, headaches, gestures, skids, collisions, fights, thought, all founded on their participants, the continuants involved in them. | |
| From: Peter Simons (Parts [1987], 8.4) | |
| A reaction: The idea of a 'moment' and 'foundation' come from Husserl Log. Inv. 3. Simons says moments 'have a bright future in ontology'. It would be better if fewer of his examples involved human beings and their perceptions. |
| 12881 | A smiling is an event with causes, but the smile is a continuant without causes [Simons] |
| Full Idea: A smiling, being an event, has causes and effects, whereas the smile thereby produced is a continuant, and has itself neither causes nor effects. | |
| From: Peter Simons (Parts [1987], 8.5) | |
| A reaction: This is dogmatic, hopeful and a bit dubious. Simons is very scathing about processes in ontology. There seem to be two descriptions, with distinctive syntax, but it is hard to believe that in reality we have two types of thing present. |
| 12882 | A wave is maintained by a process, but it isn't a process [Simons] |
| Full Idea: A wave is maintained by a process transferring motion from particle to particle of the medium, but it is not identical with this process. | |
| From: Peter Simons (Parts [1987], 8.5) | |
| A reaction: I'm inclined to think of the mind as a process. There are some 'things' which only seem to exist if they have a duration. Bricks can be instantaneous, but minds and waves can't. A wave isn't a continuant. A hill isn't a wave. |
| 12883 | Moving disturbances are are moments which continuously change their basis [Simons] |
| Full Idea: Moving disturbances are a special and interesting kind of continuant: moments which continuously change their fundaments. | |
| From: Peter Simons (Parts [1987], 8.5) | |
| A reaction: [a smile is a moment, and the face its fundament] I'm thinking he's got this wrong. Compare Idea 12882. Disturbances can't be continuants, because the passing of time is essential to them, but not to a continuant. |
| 12840 | I do not think there is a general identity condition for events [Simons] |
| Full Idea: Like Anscombe (1979) I do not think there is such a creature as a general identity condition for events. | |
| From: Peter Simons (Parts [1987], 4.1 n1) | |
| A reaction: My working definition of an event is 'any part of a process which can be individuated'. This leaves you trying to define a process, and define individuate, and then to realise that individuation is not an objective matter. |
| 12839 | Relativity has an ontology of things and events, not on space-time diagrams [Simons] |
| Full Idea: A closer examination of the concepts and principles of relativity shows that they rest squarely on an ontology of things and events (not on convenient 'space-time diagrams'). Acceleration concerns non-zero mass, but only continuants can have a mass. | |
| From: Peter Simons (Parts [1987], 3.4) | |
| A reaction: The point here is that fans of four-dimensionalism like to claim that they are more in touch with modern physics, because 'time is just another dimension, like space, so objects are spread across it'. Simons sounds right about this. |
| 12879 | Independent objects can exist apart, and maybe even entirely alone [Simons] |
| Full Idea: An object a is ontologically independent of b if a can exist without b, if there is a possible world in which in which a exists and b does not. In the strongest sense, an object is independent if it could be all there is. | |
| From: Peter Simons (Parts [1987], 8.4) | |
| A reaction: Simons calls the strongest version a 'startling' one which maybe not even God could achieve. |
| 12847 | Mass nouns admit 'much' and 'a little', and resist 'many' and 'few'. [Simons] |
| Full Idea: Syntactic criteria for mass nouns include that they admit 'much' and 'a little', and resist 'many' and 'few'. | |
| From: Peter Simons (Parts [1987], 4.6) | |
| A reaction: That is, they don't seem to be countable. Sortal terms are those which pick out countables. |
| 12863 | Mass terms (unlike plurals) are used with indifference to whether they can exist in units [Simons] |
| Full Idea: Mass terms and plural terms differ principally in the indifference of mass terms to matters of division. A mass term can be used irrespective of how, indeed whether, the denotatum comes parcelled in units. | |
| From: Peter Simons (Parts [1987], 6.4) | |
| A reaction: It seems more to the point to say that mass terms (stuff) don't need units to exist, and you can disperse the units (the cups of water) without affecting the identity of the stuff. You can't pulverise a pile of stones and retain the stones. |
| 12862 | Gold is not its atoms, because the atoms must be all gold, but gold contains neutrons [Simons] |
| Full Idea: The mass of gold cannot be identified with the gold atoms, because whatever is part of the gold atoms is gold, whereas not every part of the gold is gold (for example, the neutrons in it are not gold). | |
| From: Peter Simons (Parts [1987], 6.4) | |
| A reaction: There is something too quick about arguments like this. It comes back to nominal v real essence. We apply 'gold' to the superficial features of the stuff, but deep down we may actually mean the atomic structure. See Idea 12812. |
| 12859 | A mixture can have different qualities from its ingredients. [Simons] |
| Full Idea: The qualities of a mixture need not be those of its ingredients in isolation. | |
| From: Peter Simons (Parts [1987], 6.2) | |
| A reaction: It depends on what you mean by a quality. Presumably we can give a reductive account of the qualities of the mixture, as long as no reaction has taken place. The taste of a salad is just the sum of its parts. |
| 12858 | Mixtures disappear if nearly all of the mixture is one ingredient [Simons] |
| Full Idea: If a cupful of dirty water is mixed evenly with a ton of earth, no dirty water remains, and the same goes if we mix it evenly with a lake of clean water. | |
| From: Peter Simons (Parts [1987], 6.2) | |
| A reaction: This means that a mixture is a vague entity, subject to the sorites paradox. If the dirt was cyanide, we would consider the water to be polluted by it down to a much lower level. |
| 2469 | The world is full of messy small things producing stable large-scale properties (e.g. mountains) [Fodor] |
| Full Idea: Damn near everything we know about the world (e.g. a mountain) suggests that unimaginably complicated to-ings and fro-ings of bits and pieces at the extreme microlevel manage somehow to converge on stable macrolevel properties. | |
| From: Jerry A. Fodor (In a Critical Condition [2000], Ch. 2) | |
| A reaction: This is clearly true, and is a vital part of the physicalist picture of the mind. Personally I prefer the word 'processes' to 'properties', since no one seems to really know what a property is. A process is an abstraction from events. |
| 2475 | Don't define something by a good instance of it; a good example is a special case of the ordinary example [Fodor] |
| Full Idea: It's a mistake to try to construe the notion of an instance in terms of the notion of a good instance (e.g. Platonic Forms); the latter is patently a special case of the former, so the right order of exposition is the other way round. | |
| From: Jerry A. Fodor (In a Critical Condition [2000], Ch. 4) |
| 12850 | To individuate something we must pick it out, but also know its limits of variation [Simons] |
| Full Idea: We have not finished deciding what Fido is when we can pick him out from his surroundings at any one time. ...Knowing what Fido is depends on knowing roughly within what limits his flux of parts is tolerable. | |
| From: Peter Simons (Parts [1987], 5.2) | |
| A reaction: I like this. We don't know the world until we know its modal characteristics (its powers or dispositions). Have you 'individuated' a hand grenade if you think it is a nice ornament? |
| 12860 | Sortal nouns for continuants tell you their continuance- and cessation-conditions [Simons] |
| Full Idea: A sortal noun for a kind of continuant tells us, among other things, under what conditions the object continues to exist and under what conditions it ceases to exist. | |
| From: Peter Simons (Parts [1987], 6.3) | |
| A reaction: This sounds blatantly false. If you know something is a 'snake', that doesn't tell you how hot it must get before the snakes die. Obviously if you know all about snakes (from studying individual snakes!), then you know a lot about the next snake. |
| 12886 | A whole requires some unique relation which binds together all of the parts [Simons] |
| Full Idea: A whole must at least approximate to this condition: every member of some division of the object stands in a certain relation to every other member, and no member bears this relation to anything other than members of the division. | |
| From: Peter Simons (Parts [1987], 9.2) | |
| A reaction: Simons proceeds to formalise this, and I suspect that he goes for this definition because (unlike looser ones) it can be formalised. See Simons's Idea 12865. We'll need to know whether these are internal or external relations. |
| 12857 | Tibbles isn't Tib-plus-tail, because Tibbles can survive its loss, but the sum can't [Simons] |
| Full Idea: There mere fact that Tibbles can survive the mutilation of losing a tail, whereas the sum of Tib and the tail cannot, is enough to distinguish them, even if no such mutilation ever occurs. | |
| From: Peter Simons (Parts [1987], 6.1) | |
| A reaction: See Idea 12835 for details of the Tibbles example. Either we go for essentialism here, or the whole notion of identity collapses. But the essential features of a person are not just those whose loss would kill them. |
| 12835 | Does Tibbles remain the same cat when it loses its tail? [Simons] |
| Full Idea: The cat is 'Tibbles' with a tail; 'Tib' is Tibbles after the loss of the tail. 1) Tibbles isn't Tib at t; 2) Tibbles is Tib at t'; 3) Tibbles at t is Tibbles at t'; 4) Tib at t is Tib at t'; so 5) Tibbles at t is Tib at t (contradicting 1). What's wrong? | |
| From: Peter Simons (Parts [1987], 3.3) | |
| A reaction: [The example is in Wiggins 1979, from Geach, from William of Sherwood] Simons catalogues nine assumptions which are being made to produce the contradiction. 1) rests on Leibniz's law. Simons says two objects are occupying Tibbles. |
| 12820 | Without extensional mereology two objects can occupy the same position [Simons] |
| Full Idea: If we reject extensionality in mereology, it has as a consequence that more than one object may have exactly the same parts at the same time, and hence occupy the same position. | |
| From: Peter Simons (Parts [1987], Intro) | |
| A reaction: Simons defends this claim. I'm unconvinced that we must choose between the two views. The same parts should ensure the same physical essence, which seems to guarantee the same identity. Not any old parts generate an essence. |
| 12866 | Composition is asymmetric and transitive [Simons] |
| Full Idea: Composition is asymmetric and transitive: if a is made up of b, and b of c, then a is made up of c; and if a is made of b, then b is not made up of a. We cannot say the snow is made up of the snowball. | |
| From: Peter Simons (Parts [1987], 6.5) | |
| A reaction: ...And snowballs composed of snow can then compose a snowman (transitivity). |
| 12867 | A hand constitutes a fist (when clenched), but a fist is not composed of an augmented hand [Simons] |
| Full Idea: Composition entails constitution, but does the converse hold? A hand constitutes a fist in virtue of being clenched, but it is not obvious that it composes a fist, and certainly a fist is not composed of a hand plus some additional part. | |
| From: Peter Simons (Parts [1987], 6.5) | |
| A reaction: There are subtleties of ordinary usage in 'compose' and 'constitute' which are worth teasing apart, but that isn't the last word on such relationships. 'Compose' seems to point towards matter, while 'constitute' seems to point towards form. |
| 12864 | We say 'b is part of a', 'b is a part of a', 'b are a part of a', or 'b are parts of a'. [Simons] |
| Full Idea: There are four cases of possible forms of expression when a is made up of b: we say 'b is part of a', or 'b is a part of a', or 'b are a part of a', or 'b are parts of a'. | |
| From: Peter Simons (Parts [1987], 6.4) | |
| A reaction: Personally I don't want to make much of these observations of normal English usage, but they are still interesting, and Simons offers a nice discussion of them. |
| 12814 | Classical mereology says there are 'sums', for whose existence there is no other evidence [Simons] |
| Full Idea: Either out of conviction or for reasons of algebraic neatness, classical extensional mereology asserts the existence of certain individuals, mereological sums, for whose existence in general we have no evidence outside the theory itself. | |
| From: Peter Simons (Parts [1987], Intro) | |
| A reaction: Observing that we have no evidence for sums 'outside the theory' is nice. It is a nice ontological test, with interesting implications for Quinean ontological commitment. |
| 12817 | 'Mereological extensionality' says objects with the same parts are identical [Simons] |
| Full Idea: Classical extensional mereology won't extend well to temporal and modal facts, because of 'mereological extensionality', which is the thesis that objects with the same parts are identical (by analogy with the extensionality of sets). | |
| From: Peter Simons (Parts [1987], Intro) | |
| A reaction: Simons challenges this view, claiming, for example, that the Ship of Theseus is two objects rather than one. I suppose 'my building bricks' might be 'your sculpture', but this is very ontologically extravagant. This is a mereological Leibniz's Law. |
| 12833 | If there are c atoms, this gives 2^c - 1 individuals, so there can't be just 2 or 12 individuals [Simons] |
| Full Idea: In classical mereology, if there are c atoms, where c is any cardinal number, there are 2^c - 1 individuals, so the cardinality of models is restricted. There are no models with cardinality 2, 12 or aleph-0, for example. | |
| From: Peter Simons (Parts [1987], 1.2) | |
| A reaction: The news that there is no possible world containing just 2 or just 12 individuals ought to worry fans of extensional mereology. A nice challenge for God - create a world containing just 12 individuals. |
| 12849 | Sums are more plausible for pluralities and masses than they are for individuals [Simons] |
| Full Idea: We are on stronger grounds in asserting the general existence of sums when considering pluralities and masses than when considering individuals. | |
| From: Peter Simons (Parts [1987], 5.2) | |
| A reaction: I was thinking that the modern emphasis on referring to plurals was precisely to resist the idea that we must 'sum' them into one thing. If so, we wouldn't want to then sum several plurals. If a mass isn't a sum, how can we sum some masses? |
| 12877 | Sums of things in different categories are found within philosophy. [Simons] |
| Full Idea: Cross-categorial sums are not unknown in philosophy. A body and the events which befall it are intimately connected, and the mysterious four-dimensional blocks might be mereological sums of the body and its life. | |
| From: Peter Simons (Parts [1987], 8.1) | |
| A reaction: Simons here ventures into the territory of abstracta, which he said he wouldn't touch. Presumably his first example has 'a biography' as its whole, which is not just a philosophical notion. Why will some categories sum, and others won't? |
| 12888 | The wholeness of a melody seems conventional, but of an explosion it seems natural [Simons] |
| Full Idea: The example of a melody shows that what counts as a temporal individual is partly a matter of human stipulation. But with a natural event like an explosion there is little or no room for decision about what is a part, and whether it is a single event. | |
| From: Peter Simons (Parts [1987], 9.6) | |
| A reaction: You could have a go at giving a natural account of the wholeness of a melody, in terms of the little aesthetic explosion that occurs in the brain of a listener. |
| 12871 | Objects have their essential properties because of the kind of objects they are [Simons] |
| Full Idea: An object has the essential properties it has in virtue of being the kind of object it is. | |
| From: Peter Simons (Parts [1987], 7.1) | |
| A reaction: He attributes this to Husserl and Wiggins. I just don't get it. What makes something the 'kind of object it is'? They've got it the wrong way round. Does God announce that this thing is a tiger, and is then pleasantly surprised to discover its stripes? |
| 12870 | We must distinguish the de dicto 'must' of propositions from the de re 'must' of essence [Simons] |
| Full Idea: We must distinguish the 'must' of necessity as applied to a proposition or state of affairs (de dicto) from the 'must' of essence, concerning the way in which an object has an attribute (de re). | |
| From: Peter Simons (Parts [1987], 7.1) | |
| A reaction: A helfpful distinction, but a possible confusion of necessity and essentiality (Simons knows this). Modern logicians seem to run them together, because they only care about identity. I don't, because I care about explanations. |
| 12873 | Original parts are the best candidates for being essential to artefacts [Simons] |
| Full Idea: Original parts are the best candidates for being essential to artefacts. It is hard to conceive how an object could have as essential a part which was attached at some time after the object had come into being. | |
| From: Peter Simons (Parts [1987], 7.4) | |
| A reaction: Without its big new memory upgrade my computer would be hopelessly out of date. Simons is awesome in some ways, but seems rather confused when it comes to discussing essence. I think Wiggins may have been a bad influence on him. |
| 12874 | An essential part of an essential part is an essential part of the whole [Simons] |
| Full Idea: An essential part of an essential part is an essential part of the whole. | |
| From: Peter Simons (Parts [1987], 7.4) | |
| A reaction: Sounds beyond dispute, but worth pondering. It seems to be only type-parts, not token-parts, which are essential. Simons is thinking of identity rather than function, but he rejects Chisholm's idea that all parts are essential. So which ones are? |
| 12295 | 3-D says things are stretched in space but not in time, and entire at a time but not at a location [Fine,K] |
| Full Idea: Three-dimensionalist think a thing is somehow 'stretched out' through its location at a given time though not through the period during which it exists, and it is present in its entirety at a moment when it exists though not at a position of its location. | |
| From: Kit Fine (In Defence of Three-Dimensionalism [2006], p.1) | |
| A reaction: This definition is designed to set up Fine's defence of the 3-D view, by showing that various dubious asymmetries show up if you do not respect the distinctions offered by the 3-D view. |
| 12298 | Genuine motion, rather than variation of position, requires the 'entire presence' of the object [Fine,K] |
| Full Idea: In order to have genuine motion, rather than mere variation in position, it is necessary that the object should be 'entirely present' at each moment of the change. Thus without entire presence, or existence, genuine motion will not be possible. | |
| From: Kit Fine (In Defence of Three-Dimensionalism [2006], p.6) | |
| A reaction: See Idea 4786 for a rival view of motion. Of course, who says we have to have Kit Fine's 'genuine' motion, if some sort of ersatz motion still gets you to work in the morning? |
| 12296 | 4-D says things are stretched in space and in time, and not entire at a time or at a location [Fine,K] |
| Full Idea: Four-dimensionalists have thought that a material thing is as equally 'stretched out' in time as it is in space, and that there is no special way in which it is entirely present at a moment rather than at a position. | |
| From: Kit Fine (In Defence of Three-Dimensionalism [2006], p.1) | |
| A reaction: Compare his definition of 3-D in Idea 12295. The 4-D is contrary to our normal way of thinking. Since I don't think the future exists, I presume that if I am a 4-D object then I have to say that I don't yet exist, and I disapprove of such talk. |
| 18882 | You can ask when the wedding was, but not (usually) when the bride was [Fine,K, by Simons] |
| Full Idea: Fine says it is acceptable to ask when a wedding was and where it was, and it is acceptable to ask or state where the bride was (at a certain time), but not when she was. | |
| From: report of Kit Fine (In Defence of Three-Dimensionalism [2006], p.18) by Peter Simons - Modes of Extension: comment on Fine p.18 | |
| A reaction: This is aimed at three-dimensionalists who seem to think that a bride is a prolonged event, just as a wedding is. Fine is, interestingly, invoking ordinary language. When did the wedding start and end? When was the bride's birth and death? |
| 12837 | Four dimensional-objects are stranger than most people think [Simons] |
| Full Idea: The strangeness of four-dimensional objects is almost always underestimated in the literature. | |
| From: Peter Simons (Parts [1987], 3.4) | |
| A reaction: See Idea 12836, where he has criticised process ontologists for smuggling in stages and process as being OF conventional objects. |
| 12297 | Three-dimensionalist can accept temporal parts, as things enduring only for an instant [Fine,K] |
| Full Idea: Even if one is a three-dimensionalist, one might affirm the existence of temporal parts, on the grounds that everything merely endures for an instant. | |
| From: Kit Fine (In Defence of Three-Dimensionalism [2006], p.2) | |
| A reaction: This seems an important point, as belief in temporal parts is normally equated with four-dimensionalism (see Idea 12296). The idea is that a thing might be 'entirely present' at each instant, only to be replaced by a simulacrum. |
| 12856 | Intermittent objects would be respectable if they occurred in nature, as well as in artefacts [Simons] |
| Full Idea: If we could show that intermittence could occur not only among artefacts and higher-order objects, but also among natural things, then we should have given it a secure place on the ontological map. | |
| From: Peter Simons (Parts [1987], 5.7) | |
| A reaction: Interesting ontological test. Having identified fairly clear intermittent artefacts (Idea 12851), if we then fail to find any examples in nature, must we revisit the artefacts and say they are not intermittents? He suggests freezing an organ in surgery. |
| 12885 | Objects like chess games, with gaps in them, are thereby less unified [Simons] |
| Full Idea: Temporal objects which are scattered in time - i.e. have temporal gaps in them, like interrupted discussions or chess games - are less unified than those without gaps. | |
| From: Peter Simons (Parts [1987], 9.2) | |
| A reaction: Is he really saying that a discussion or a chess game is less unified if there is even the slightest pause in it? Otherwise, how long must the pause be before it disturbs the unity? Do people play internet chess, as they used to play correspondence chess? |
| 12854 | An entrepreneur and a museum curator would each be happy with their ship at the end [Simons] |
| Full Idea: At the end of the Ship of Theseus story both an entrepreneur and a museum curator can be content, each having his ship all to himself, ..because each was all along claiming a different object from the other. | |
| From: Peter Simons (Parts [1987], 5.5) | |
| A reaction: Simons has the entrepreneur caring about function (for cruises), and the curator caring about matter (as a relic of Theseus). It is bold of Simons to say on that basis that it starts as two objects, one 'matter-constant', the other 'form-constant'. |
| 12855 | The 'best candidate' theories mistakenly assume there is one answer to 'Which is the real ship?' [Simons] |
| Full Idea: The 'best candidate' theories get into difficulty because it is assumed that there is a single uniquely correct answer to the question 'Which is the real ship?' | |
| From: Peter Simons (Parts [1987], 5.5) | |
| A reaction: My own example supports Simons. If Theseus discards the old planks as rubbish, then his smart new ship is the original. But if he steals his own ship (to evade insurance regulations) by substituting a plank at a time, the removed planks are the original. |
| 12872 | The zygote is an essential initial part, for a sexually reproduced organism [Simons] |
| Full Idea: It is essential to an organism arising from sexual reproduction that it has its zygote as initial improper part. | |
| From: Peter Simons (Parts [1987], 7.3) | |
| A reaction: It can't be necessary that an organism which appears to be sexually reproduced actually is so (if you don't believe that, read more science fiction). It may well just be analytic that sexual reproduction involves a zygote. Nothing to do with essence. |
| 12889 | The limits of change for an individual depend on the kind of individual [Simons] |
| Full Idea: What determines the limits of admissible change and secures the identity of a continuant is a matter of the kind of object in question. | |
| From: Peter Simons (Parts [1987], 9.6) | |
| A reaction: This gives some motivation for the sortal view of essence, which I find hard to take. However, if my statue were pulverised it would make good compost. |
| 2502 | How do you count beliefs? [Fodor] |
| Full Idea: There is no agreed way of counting beliefs. | |
| From: Jerry A. Fodor (In a Critical Condition [2000], Ch.16) |
| 2501 | Berkeley seems to have mistakenly thought that chairs are the same as after-images [Fodor] |
| Full Idea: Berkeley seems to have believed that tables and chairs are logically homogeneous with afterimages. I assume that he was wrong to believe this. | |
| From: Jerry A. Fodor (In a Critical Condition [2000], Ch.16) |
| 2465 | Maybe explaining the mechanics of perception will explain the concepts involved [Fodor] |
| Full Idea: Why mightn't fleshing out the standard psychological account of perception itself count as learning what perceptual justification amounts to? | |
| From: Jerry A. Fodor (In a Critical Condition [2000], Ch. 1) |
| 2504 | Rationalism can be based on an evolved computational brain with innate structure [Fodor] |
| Full Idea: Pinker's rationalism involves four main ideas: mind is a computational system, which is massively modular with a lot of innate structure resulting from evolution. | |
| From: Jerry A. Fodor (In a Critical Condition [2000], Ch.17) |
| 2493 | According to empiricists abstraction is the fundamental mental process [Fodor] |
| Full Idea: According to empiricists, the fundamental mental process is not theory construction but abstraction. | |
| From: Jerry A. Fodor (In a Critical Condition [2000], Ch.12) |
| 2494 | Rationalists say there is more to a concept than the experience that prompts it [Fodor] |
| Full Idea: That there is more in the content of a concept than there is in the experiences that prompt us to form it is the burden of the traditional rationalist critique of empiricism (as worked out by Leibniz and Kant). | |
| From: Jerry A. Fodor (In a Critical Condition [2000], Ch.12) |
| 2503 | Empirical approaches see mind connections as mirrors/maps of reality [Fodor] |
| Full Idea: Empirical approaches to cognition say the human mind is a blank slate at birth; experiences write on the slate, and association extracts and extrapolates trends from the record of experience. The mind is an image of statistical regularities of the world. | |
| From: Jerry A. Fodor (In a Critical Condition [2000], Ch.17) | |
| A reaction: The 'blank slate' is an exaggeration. The mind at least has the tools to make associations. He tries to make it sound implausible, but the word 'extrapolates' contains a wealth of possibilities that could build into a plausible theory. |
| 2508 | The function of a mind is obvious [Fodor] |
| Full Idea: Like hands, you don't have to know how the mind evolved to make a pretty shrewd guess at what it's for; for example, that it's to think with. | |
| From: Jerry A. Fodor (In a Critical Condition [2000], Ch.17) | |
| A reaction: I like this. This is one of the basic facts of philosophy of mind, and it frequently gets lost in the fog. It is obvious that the components of the mind (say, experience and intentionality) will be better understood if their function is remembered. |
| 2485 | Do intentional states explain our behaviour? [Fodor] |
| Full Idea: Intentional Realism is the idea that our intentional mental states causally explain our behaviour; so holistic semantics (which says no two people have the same intentional states, or share generalisations) is irrealistic about intentional mental states. | |
| From: Jerry A. Fodor (In a Critical Condition [2000], Ch. 6) | |
| A reaction: ...presumably because two people CAN have the same behaviour. The key question would be whether the intentional states have to be conscious. |
| 2506 | If I have a set of mental modules, someone had better be in charge of them! [Fodor] |
| Full Idea: If there is a community of computers living in my head, there had also better be somebody who is in charge; and, by God, it had better be me. | |
| From: Jerry A. Fodor (In a Critical Condition [2000], Ch.17) | |
| A reaction: Dennett quotes this as a quaintly old-fashioned view. I agree quite strongly with Fodor, for reasons that Dennett should like - evolutionary ones. A mind is a useless tool without central co-ordination. What makes my long-term plans? It isn't anarchy! |
| 2467 | Functionalists see pains as properties involving relations and causation [Fodor] |
| Full Idea: Functionalists claim that pains and the like are higher-order, relational properties that things have in virtue of the pattern of causal interactions that they (can or do) enter into. | |
| From: Jerry A. Fodor (In a Critical Condition [2000], Ch. 2) | |
| A reaction: The whole idea of a property being purely 'relational' strikes me as dubious (or even nonsense). "Is north of" is a relation, but it is totally derived from more basical physical geographical properties. |
| 2489 | Why bother with neurons? You don't explain bird flight by examining feathers [Fodor] |
| Full Idea: Compare Churchland's strategy rooted in neurological modelling with "if it's flight you want to understand, what you need to look at is feathers". | |
| From: Jerry A. Fodor (In a Critical Condition [2000], Ch. 8) | |
| A reaction: Sounds good, but may be a false analogy. You learn a lot about snake movement if you examine their scales. |
| 2468 | Type physicalism is a stronger claim than token physicalism [Fodor] |
| Full Idea: "Type" physicalism is supposed, by general consensus, to be stronger than "token" physicalism; stronger, that is, than the mere claim that all mental states are necessarily physically instantiated. | |
| From: Jerry A. Fodor (In a Critical Condition [2000], Ch. 2) | |
| A reaction: Such philosopher's terminology always seems cut-and-dried, until you ask exactly what is identical to what. The word 'type' is a very broad concept. Are trees the same type of thing as roses? A thought always requires the same 'type' of brain event? |
| 2490 | Modern connectionism is just Hume's theory of the 'association' of 'ideas' [Fodor] |
| Full Idea: Churchland is pushing a version of connectionism ….in which if you think of the elements as "ideas" and call the connections between them "associations", you've got a psychology that is no great advance on David Hume. | |
| From: Jerry A. Fodor (In a Critical Condition [2000], Ch. 8) | |
| A reaction: See Fodor's book 'Humean Variations' on how Hume should be improved. This idea strikes me as important for understanding Hume, who is very reticent about what his real views are on the mind. |
| 2476 | The goal of thought is to understand the world, not instantly sort it into conceptual categories [Fodor] |
| Full Idea: The question whether there are recognitional concepts is really the question what thought is for - for directing action, or for discerning truth. And Descartes was right on this: the goal of thought is to understand the world, not to sort it. | |
| From: Jerry A. Fodor (In a Critical Condition [2000], Ch. 4) |
| 2499 | Modules analyse stimuli, they don't tell you what to do [Fodor] |
| Full Idea: The thinking involved in "figuring out" what to do is a quite different kind of mental process than the stimulus analysis that modules perform. | |
| From: Jerry A. Fodor (In a Critical Condition [2000], Ch.13) | |
| A reaction: My PA theory fits this perfectly. My inner assistant keeps providing information about needs, duties etc., but takes no part in my decisions. Psychology must include the Will. |
| 2496 | Blindness doesn't destroy spatial concepts [Fodor] |
| Full Idea: Blind children are not, in general, linguistically impaired; not even in their talk about space. | |
| From: Jerry A. Fodor (In a Critical Condition [2000], Ch.13) | |
| A reaction: This is offered to demonstrate that spatial concepts are innate, even in the blind. But then we would expect anyone who has to move in space to develop spatial concepts from experience. |
| 2497 | Something must take an overview of the modules [Fodor] |
| Full Idea: It is not plausible that the mind could be made only of modules; one does sometimes manage to balance one's checkbook, and there can't be an innate, specialized intelligence for doing that. | |
| From: Jerry A. Fodor (In a Critical Condition [2000], Ch.13) | |
| A reaction: I agree strongly with this. My own mind strikes me as being highly modular, but as long as I am aware of the output of the modules, I can pass judgement. The judger is more than a 'module'. |
| 2509 | Modules have in-built specialist information [Fodor] |
| Full Idea: Modules contain lots of specialized information about the problem domains that they compute in. | |
| From: Jerry A. Fodor (In a Critical Condition [2000], Ch.17) | |
| A reaction: At this point we must be cautious about modularity. I doubt whether 'information' is the right word. I think 'specialized procedures' might make more sense. |
| 2491 | Modules have encapsulation, inaccessibility, private concepts, innateness [Fodor] |
| Full Idea: The four essential properties of modules are: encapsulation (information doesn't flow, as in the persistence of illusions); inaccessibility (unreportable); domain specificity (they have private concepts); innateness (genetically preprogrammed). | |
| From: Jerry A. Fodor (In a Critical Condition [2000], Ch.11) | |
| A reaction: If they have no information flow, and are unreportable and private, this makes empirical testing of Fodor's hypothesis a little tricky. He must be on to something, though. |
| 2495 | Obvious modules are language and commonsense explanation [Fodor] |
| Full Idea: The best candidates for the status of mental modules are language (the first one, put there by Chomsky), commonsense biology, commonsense physics, commonsense psychology, and aspects of visual form perception. | |
| From: Jerry A. Fodor (In a Critical Condition [2000], Ch.13) | |
| A reaction: My favourite higher level module is my Personal Assistant, who keeps nagging me to do sundry things, only some of which I agree to. It is an innate superego, but still a servant of the Self. |
| 2507 | Rationality rises above modules [Fodor] |
| Full Idea: Probably, modular computation doesn't explain how minds are rational; it's just a sort of precursor. You work through it to get a view of how horribly hard our rationality is to understand. | |
| From: Jerry A. Fodor (In a Critical Condition [2000], Ch.17) | |
| A reaction: The choice is between a Self which weighs and judges the inputs, or merely decisions that automatically result from the balance of inputs. The latter seems unlikely. Vetoes are essential. |
| 2498 | Modules make the world manageable [Fodor] |
| Full Idea: Modules function to present the world to thought under descriptions that are germane to the success of behaviour. | |
| From: Jerry A. Fodor (In a Critical Condition [2000], Ch.13) | |
| A reaction: "Descriptions" might be a bold word to use about something so obscure, but this pinpoints the evolutionary nature of modularity theory, to which I subscribe. |
| 2500 | Babies talk in consistent patterns [Fodor] |
| Full Idea: "Who Mummy love?" is recognizably baby talk; but "love Mummy who?" is not. | |
| From: Jerry A. Fodor (In a Critical Condition [2000], Ch.14) | |
| A reaction: Not convincing. If she is embracing Daddy, and asking baby, she might get the answer "Daddy", after a bit of coaxing. Who knows what babies up the Amazon respond to? |
| 2483 | Mentalese doesn't require a theory of meaning [Fodor] |
| Full Idea: Mentalese doesn't need Grice's theory of natural-language meaning, or indeed any theory of natural-language meaning whatsoever. | |
| From: Jerry A. Fodor (In a Critical Condition [2000], Ch. 6) | |
| A reaction: Presumably what is represented by mentalese is a quite separate question from whether there exists a mentalese that does some sort of representing. Sounds plausible. |
| 2480 | Language is ambiguous, but thought isn't [Fodor] |
| Full Idea: Thinking can't just be in sequences of English words since, notoriously, thought needs to be ambiguity-free in ways that mere word sequences are not. | |
| From: Jerry A. Fodor (In a Critical Condition [2000], Ch. 6) | |
| A reaction: I think this is a strong argument in favour of (at least) propositions. Thoughts are unambiguous, but their expression need not be. Sentences could be expanded to achieve clarity. |
| 2487 | Mentalese may also incorporate some natural language [Fodor] |
| Full Idea: I don't think it is true that all thought is in Mentalese. It is quite likely (e.g. in arithmetic algorithms) that Mentalese co-opts bits of natural language. | |
| From: Jerry A. Fodor (In a Critical Condition [2000], Ch. 6) | |
| A reaction: Presumably language itself would have to be coded in mentalese. If there is some other way for thought to work, the whole mind could use it, and skip mentalese. |
| 2486 | Content can't be causal role, because causal role is decided by content [Fodor] |
| Full Idea: Functional role semantics wants to analyze the content of a belief in terms of its inferential (causal) relations; but that seems the wrong way round. The content of a belief determines its causal role. | |
| From: Jerry A. Fodor (In a Critical Condition [2000], Ch. 6) | |
| A reaction: This is one of my favourite ideas, which keeps coming to mind when considering functional accounts of mental life. The buck of explanation must, however, stop somewhere. |
| 2492 | Experience can't explain itself; the concepts needed must originate outside experience [Fodor] |
| Full Idea: Experience can't explain itself; eventually, some of the concepts that explaining experience requires have to come from outside it. Eventually, some of them have to be built in. | |
| From: Jerry A. Fodor (In a Critical Condition [2000], Ch.12) |
| 2471 | Are concepts best seen as capacities? [Fodor] |
| Full Idea: Virtually all modern theorists about philosophy, mind or language tend to agree that concepts are capacities, in particular concepts are epistemic capacities. | |
| From: Jerry A. Fodor (In a Critical Condition [2000], Ch. 3) | |
| A reaction: This view seems to describe concepts in functional terms, which generates my perennial question: what is it about concepts that enables them to fulfil that particular role? |
| 2472 | For Pragmatists having a concept means being able to do something [Fodor] |
| Full Idea: It's a paradigmatically Pragmatist idea that having a concept consists in being able to do something. | |
| From: Jerry A. Fodor (In a Critical Condition [2000], Ch. 3) | |
| A reaction: If you defined a bicycle simply by what you could do with it, you wouldn't explain much. I wonder if pragmatism and functionalism come from the same intellectual stable? |
| 2482 | It seems unlikely that meaning can be reduced to communicative intentions, or any mental states [Fodor] |
| Full Idea: Nobody now thinks that the reduction of the meaning of English sentences to facts about the communicative intentions of English speakers - or to any facts about mental states - is likely to go through. | |
| From: Jerry A. Fodor (In a Critical Condition [2000], Ch. 6) | |
| A reaction: Most attempts at 'reduction' of meaning seem to go rather badly. I assume it would be very difficult to characterise 'intentions' without implicit reference to meaning. |
| 2477 | If to understand "fish" you must know facts about them, where does that end? [Fodor] |
| Full Idea: If learning that fish typically live in streams is part of learning "fish", typical utterances of "pet fish" (living in bowls) are counterexamples. This argument iterates (e.g "big pet fish"). So learning where they live can't be part of learning "fish". | |
| From: Jerry A. Fodor (In a Critical Condition [2000], Ch. 5) | |
| A reaction: Using 'typical' twice is rather misleading here. Town folk can learn 'fish' as typically living in bowls. There is no one way to learn a word meaning. |
| 2473 | Analysis is impossible without the analytic/synthetic distinction [Fodor] |
| Full Idea: If there is no analytic/synthetic distinction then there are no analyses. | |
| From: Jerry A. Fodor (In a Critical Condition [2000], Ch. 3) | |
| A reaction: There are no precise analyses. I see no reason why a holistic view of language prohibits the careful elucidation of key concepts in the system. It's just a bit fluid. |
| 2484 | The theory of the content of thought as 'Mentalese' explains why the Private Language Argument doesn't work [Fodor] |
| Full Idea: If the Mentalese story about the content of thought is true, then there couldn't be a Private Language Argument. Good. That explains why there isn't one. | |
| From: Jerry A. Fodor (In a Critical Condition [2000], Ch. 6) | |
| A reaction: Presumably Mentalese implies that all language is, in the first instance, intrinsically private. Dogs, for example, need Mentalese, since they self-evidently think. |
| 12843 | With activities if you are doing it you've done it, with performances you must finish to have done it [Simons] |
| Full Idea: Action theorists distinguish between activity verbs such as 'weep' and 'talk' (where continuous entails perfect - John is weeping so John has now wept), and performance verbs like 'wash', where John is washing doesn't yet mean John has washed. | |
| From: Peter Simons (Parts [1987], 4.2) | |
| A reaction: How to distinguish them, bar examples? In 'has wept' and 'has washed', I'm thinking that it is the 'has' which is ambiguous, rather than the more contentful word. One is 'has participated' and the other is 'has completed'. I've participated in washing! |
| 12875 | One false note doesn't make it a performance of a different work [Simons] |
| Full Idea: A performance of a certain work with a false note is still a performance of that work, albeit a slightly imperfect one, and not (as Goodman has argued) a performance of a different work. | |
| From: Peter Simons (Parts [1987], 7.6) | |
| A reaction: This is clearly right, but invites the question of how many wrong notes are permissable. One loud very wrong note could ruin a very long performance (but of that work, presumably). This is about classical music, but think about jazz. |
