14480 | Maybe analytic truths do not require truth-makers, as they place no demands on the world [Thomasson] |
Full Idea: It is a venerable view that analytic claims do not require truth-makers, as they place no demands on the world, but this claim has often been challenged. | |
From: Amie L. Thomasson (Ordinary Objects [2007], 03.4) | |
A reaction: She offers two challenges (bottom p.68), but I would have thought that the best response is that the meanings of the words themselves constitute truthmakers - perhaps via the essence of each word, as Fine suggests. |
14471 | Analytical entailments arise from combinations of meanings and inference rules [Thomasson] |
Full Idea: 'Analytically entail' means entail in virtue of the meanings of the expressions involved and rules of inference. So 'Jones bought a house' analytically entails 'Jones bought a building'. | |
From: Amie L. Thomasson (Ordinary Objects [2007], 01.2) | |
A reaction: Quine wouldn't like this, but it sounds OK to me. Thomasson uses this as a key tool in her claim that common sense objects must exist. |
4975 | A thought can be split in many ways, so that different parts appear as subject or predicate [Frege] |
Full Idea: A thought can be split up in many ways, so that now one thing, now another, appears as subject or predicate | |
From: Gottlob Frege (On Concept and Object [1892], p.199) | |
A reaction: Thus 'the mouse is in the box', and 'the box contains the mouse'. A simple point, but important when we are trying to distinguish thought from language. |
9949 | There is the concept, the object falling under it, and the extension (a set, which is also an object) [Frege, by George/Velleman] |
Full Idea: For Frege, the extension of the concept F is an object, as revealed by the fact that we use a name to refer to it. ..We must distinguish the concept, the object that falls under it, and the extension of the concept, which is the set containing the object. | |
From: report of Gottlob Frege (On Concept and Object [1892]) by A.George / D.J.Velleman - Philosophies of Mathematics Ch.2 | |
A reaction: This I take to be the key distinction needed if one is to grasp Frege's account of what a number is. When we say that Frege is a platonist about numbers, it is because he is committed to the notion that the extension is an object. |
18995 | Frege mistakenly takes existence to be a property of concepts, instead of being about things [Frege, by Yablo] |
Full Idea: Frege's theory treats existence as a property, not of things we call existent, but of concepts instantiated by those things. 'Biden exists' says our Biden-concept has instances. That is certainly not how it feels! We speak of the thing, not of concepts. | |
From: report of Gottlob Frege (On Concept and Object [1892]) by Stephen Yablo - Aboutness 01.4 | |
A reaction: Yablo's point is that you must ask what the sentence is 'about', and then the truth will refer to those things. Frege gets into a tangle because he thinks remarks using concepts are about the concepts. |
14493 | Existence might require playing a role in explanation, or in a causal story, or being composed in some way [Thomasson] |
Full Idea: A higher standard for saying that entities exist might require that they play an essential role in explanation, or must figure in any complete causal story, or exist according to some uniform and nonarbitrary principle of composition. | |
From: Amie L. Thomasson (Ordinary Objects [2007], 11.2) | |
A reaction: I am struck by the first of these three. If I am defending the notion that essence depends on Aristotle's account of explanation, then if we add that existence also depends on explanation, we get a criterion for the existence of essences. Yay. |
14491 | Rival ontological claims can both be true, if there are analytic relationships between them [Thomasson] |
Full Idea: Where there are analytic interrelations among our claims, distinct ontological claims may be true without rivalry, redundancy, or reduction. | |
From: Amie L. Thomasson (Ordinary Objects [2007], 10) | |
A reaction: Thus we might, I suppose, that it is analytically necessary that a lump of clay has a shape, and that a statue be made of something. Interesting. |
14489 | Theories do not avoid commitment to entities by avoiding certain terms or concepts [Thomasson] |
Full Idea: A theory does not avoid commitment to any entities by avoiding use of certain terms or concepts. | |
From: Amie L. Thomasson (Ordinary Objects [2007], 09.4) | |
A reaction: This is a salutary warning to those who apply the notion of ontological commitment rather naively. |
10317 | It is unclear whether Frege included qualities among his abstract objects [Frege, by Hale] |
Full Idea: Expositors of Frege's views have disagreed over whether abstract qualities are to be reckoned among his objects. | |
From: report of Gottlob Frege (On Concept and Object [1892]) by Bob Hale - Abstract Objects Ch.2.II | |
A reaction: [he cites Dummett 1973:70-80, and Wright 1983:25-8] There seems to be a danger here of a collision between Fregean verbal approaches to ontological commitment and the traditional views about universals. No wonder they can't decide. |
14485 | Ordinary objects may be not indispensable, but they are nearly unavoidable [Thomasson] |
Full Idea: I do not argue that ordinary objects are indispensable, but rather that they are (nearly) unavoidable. | |
From: Amie L. Thomasson (Ordinary Objects [2007], 09) | |
A reaction: Disappointing, given the blurb and title of the book, but put in those terms it will be hard to disagree. Clearly ordinary objects figure in the most useful way for us to talk. I wonder whether we have a clear ontology of 'simples' in which they vanish. |
14487 | The simple existence conditions for objects are established by our practices, and are met [Thomasson] |
Full Idea: The existence conditions for ordinary objects are established by our practices, and they are quite minimal, so it is rather obvious that they are fulfilled, and so there are such things. | |
From: Amie L. Thomasson (Ordinary Objects [2007], 09.3) | |
A reaction: This is one of her main arguments. The same argument would have worked for witches or ghosts in certain cultures. |
10535 | Frege's 'objects' are both the referents of proper names, and what predicates are true or false of [Frege, by Dummett] |
Full Idea: Frege's notion of an object plays two roles in his semantics. Objects are the referents of proper names, and they are equally what predicates are true and false of. | |
From: report of Gottlob Frege (On Concept and Object [1892]) by Michael Dummett - Frege Philosophy of Language (2nd ed) Ch.4 | |
A reaction: Frege is the source of a desperate desire to turn everything into an object (see Idea 8858!), and he has the irritating authority of the man who invented quantificational logic. Nothing but trouble, that man. |
21651 | It is analytic that if simples are arranged chair-wise, then there is a chair [Thomasson, by Hofweber] |
Full Idea: Thomasson argues that the existence of ordinary objects follows analytically from the distribution of simples, assuming that there are any simples. It is an analytic truth that if there are simples arranged chair-wise, then there is a chair. | |
From: report of Amie L. Thomasson (Ordinary Objects [2007]) by Thomas Hofweber - Ontology and the Ambitions of Metaphysics 07.3 | |
A reaction: But how do you distinguish when simples are arranged nearly chair-wise from the point where they click into place as actually chair-wise? What is the criterion? |
14467 | Ordinary objects are rejected, to avoid contradictions, or for greater economy in thought [Thomasson] |
Full Idea: Objections to ordinary objects are the Causal Redundancy claim (objects lack causal powers), the Anti-Colocation view (statues and lumps overlap), Sorites arguments, a more economical ontology, or a more scientific ontology. | |
From: Amie L. Thomasson (Ordinary Objects [2007], Intro) | |
A reaction: [my summary of two paragraphs] The chief exponents of these views are Van Inwagen and Merricks. Before you glibly accept ordinary objects, you must focus on producing a really strict ontology. These arguments all have real force. |
14479 | To individuate people we need conventions, but conventions are made up by people [Thomasson] |
Full Idea: The conventionalist faces paradox if they hold that conventions are logically prior to people (since this plurality requires conventions of individuation), and people are logically prior to conventions (if they make up the conventions). | |
From: Amie L. Thomasson (Ordinary Objects [2007], 03.3) | |
A reaction: [Sidelle is the spokesman for conventionalism] The best defence would be to deny the second part, and say that conventions emerge from whatever is there, but only conventions can individuate the bits of what is there. |
14486 | Eliminativists haven't found existence conditions for chairs, beyond those of the word 'chair' [Thomasson] |
Full Idea: The eliminativist cannot claim to have 'discovered' some real existence conditions for chairs beyond those entailed by the semantic rules associated with ordinary use of the word 'chair'. | |
From: Amie L. Thomasson (Ordinary Objects [2007], 09.3) | |
A reaction: It is difficult to understand atoms arranged 'chairwise' or 'baseballwise' if you don't already know what a chair or a baseball are. |
14481 | Wherever an object exists, there are intrinsic properties instantiating every modal profile [Thomasson] |
Full Idea: In a 'modally plenitudinous' ontology, wherever there is an object at all, there are objects with intrinsic modal properties instantiating every consistent modal profile. | |
From: Amie L. Thomasson (Ordinary Objects [2007], 03.5) | |
A reaction: [She cites K.Bennett, Hawley, Rea, Sidelle] I love this. At last a label for the view I have been espousing. I am a Modal Plenitudinist. I must get a badge made. |
14482 | If the statue and the lump are two objects, they require separate properties, so we could add their masses [Thomasson] |
Full Idea: An objection to the idea that statues are not identical to material lumps of stuff is the proliferation of instances of properties shared by those objects. If the mass of the statue is 500kg, and the mass of the lump is 500kg, do we have 1000kg? | |
From: Amie L. Thomasson (Ordinary Objects [2007], 04.3) | |
A reaction: [compressed; she cites Rea 1997 and Zimmerman 1995] To wriggle out of this we would have to understand 'object' rather differently, so that an independent mass is not intrinsic to it. I leave this as an exercise for the reader. |
14483 | Given the similarity of statue and lump, what could possibly ground their modal properties? [Thomasson] |
Full Idea: The 'grounding problem' is that given all that the statue and the lump have in common, what could possibly ground their different modal properties? | |
From: Amie L. Thomasson (Ordinary Objects [2007], 04.4) | |
A reaction: Their modal properties are, of course, different, because only one of them could survive squashing. Thomasson suggests their difference of sort, but I'm not sure what that means, separately from what they actually are. |
14476 | Identity claims between objects are only well-formed if the categories are specified [Thomasson] |
Full Idea: Identity claims are only well-formed and truth-evaluable if the terms flanking the statement are associated with a certain category of entity each is to refer to, which disambiguates the reference and identity-criteria. | |
From: Amie L. Thomasson (Ordinary Objects [2007], 03) | |
A reaction: The first of her two criteria for identity. She is buying the full Wiggins package. |
14477 | Identical entities must be of the same category, and meet the criteria for the category [Thomasson] |
Full Idea: Identity claims are only true if the entities referred to are of the same category, and meet the criteria of identity appropriate for things of that category. | |
From: Amie L. Thomasson (Ordinary Objects [2007], 03) | |
A reaction: This may be a little too optimistic about having a set of clear-cut and reasonably objective categories to work with, but attempts at establishing metaphysical categories have not gone especially well. |
14478 | Modal Conventionalism says modality is analytic, not intrinsic to the world, and linguistic [Thomasson] |
Full Idea: Modal Conventionalism has at least three theses: 1) modal truths are either analytic truths, or combine analytic and empirical truths, 2) modal properties are not intrinsic features of the world, 3) modal propositions depend on linguistic conventions. | |
From: Amie L. Thomasson (Ordinary Objects [2007], 03.2) | |
A reaction: [She cites Alan Sidelle 1989 for this view] I disagree mainly with number 2), since I take dispositions to be key intrinsic features of nature, and I interpret dispositions as modal properties. |
14466 | A chief task of philosophy is making reflective sense of our common sense worldview [Thomasson] |
Full Idea: Showing how, reflectively, we can make sense of our unreflective common sense worldview is arguably one of the chief tasks of philosophy. | |
From: Amie L. Thomasson (Ordinary Objects [2007], Intro) | |
A reaction: Maybe. The obvious problem is that when you look at weird and remote cultures like the Aztecs, what counts as 'common sense' might be a bit different. She is talking of ordinary objects, though, where her point is reasonable. |
9839 | Frege equated the concepts under which an object falls with its properties [Frege, by Dummett] |
Full Idea: Frege equated the concepts under which an object falls with its properties. | |
From: report of Gottlob Frege (On Concept and Object [1892], p.201) by Michael Dummett - Frege philosophy of mathematics Ch.8 | |
A reaction: I take this to be false, as objects can fall under far more concepts than they have properties. I don't even think 'being a pencil' is a property of pencils, never mind 'being my favourite pencil', or 'not being Alexander the Great'. |
4973 | As I understand it, a concept is the meaning of a grammatical predicate [Frege] |
Full Idea: As I understand it, a concept is the meaning of a grammatical predicate. | |
From: Gottlob Frege (On Concept and Object [1892], p.193) | |
A reaction: All the ills of twentieth century philosophy reside here, because it makes a concept an entirely linguistic thing, so that animals can't have concepts, and language is cut off from reality, leading to relativism, pragmatism, and other nonsense. |
9167 | Frege felt that meanings must be public, so they are abstractions rather than mental entities [Frege, by Putnam] |
Full Idea: Frege felt that meanings are public property, and identified concepts (and hence 'intensions' or meanings) with abstract entities rather than mental entities. | |
From: report of Gottlob Frege (On Concept and Object [1892]) by Hilary Putnam - Meaning and Reference p.150 | |
A reaction: This is the germ of Wittgenstein's private language argument. I am inclined to feel that Frege approached language strictly as a logician, and didn't really care that he got himself into implausible platonist ontological commitments. |
14475 | How can causal theories of reference handle nonexistence claims? [Thomasson] |
Full Idea: Pure causal theories of reference have problems in handling nonexistence claims | |
From: Amie L. Thomasson (Ordinary Objects [2007], 02.3) | |
A reaction: This is a very sound reason for shifting from a direct causal baptism view to one in which the baptism takes place by a social consensus. So there is a consensus about 'unicorns', but obviously no baptism. See Evans's 'Madagascar' example. |
14474 | Pure causal theories of reference have the 'qua problem', of what sort of things is being referred to [Thomasson] |
Full Idea: Pure causal theories of reference face the 'qua problem' - that it may be radically indeterminate what the term refers to unless there is some very basic concept of what sort of thing is being referred to. | |
From: Amie L. Thomasson (Ordinary Objects [2007], 02.3) | |
A reaction: She cites Dummett and Wiggins on this. There is an obvious problem that when I say 'look at that!' there are all sorts of conventions at work if my reference is to succeed. |
4974 | For all the multiplicity of languages, mankind has a common stock of thoughts [Frege] |
Full Idea: For all the multiplicity of languages, mankind has a common stock of thoughts. | |
From: Gottlob Frege (On Concept and Object [1892], p.196n) | |
A reaction: Given the acknowledgement here that two very different sentences in different languages can express the same thought, he should recognise that at least some aspects of a thought are non-linguistic. |
14488 | Analyticity is revealed through redundancy, as in 'He bought a house and a building' [Thomasson] |
Full Idea: The analytic interrelations among elements of language become evident through redundancy. It is redundant to utter 'He bought a house and a building', since buying a house analytically entails that he bought a building. | |
From: Amie L. Thomasson (Ordinary Objects [2007], 09.4) | |
A reaction: This appears to concern necessary class membership. It is only linguistically redundant if the class membership is obvious. Houses are familiar, uranium samples are not. |
15998 | Perfect love is not in spite of imperfections; the imperfections must be loved as well [Kierkegaard] |
Full Idea: To love another in spite of his weaknesses and errors and imperfections is not perfect love. No, to love is to find him lovable in spite of, and together with, his weaknesses and errors and imperfections. | |
From: Søren Kierkegaard (Works of Love [1847], p.158) | |
A reaction: A true romantic at heart, Kierkegaard ideally posits perfect love as unconditional love, and not just of good attributes, predicates and conditions. However, the real question for both me and Kierkegaard is, is perfect love desirable or even possible?[SY] |
