15395 | Give up objects necessitating truths, and say their natures cause the truths? [Cameron] |
Full Idea: We could abandon the view that truthmakers necessitate the truth of that which makes them true, and say that an object makes a truth when its intrinsic nature suffices for that truth. The object would have a different intrinsic nature if the truth failed. | |
From: Ross P. Cameron (Intrinsic and Extrinsic Properties [2009], 'Truthmakers') | |
A reaction: [He cites Josh Parsons 1999, 2005 for this] This approach seems closely related to Kit Fine's proposal that necessities arise from the natures of things. It sounds to me as if an object with that intrinsic nature would necessitate that truth. |
15394 | Truthmaker requires a commitment to tropes or states of affairs, for contingent truths [Cameron] |
Full Idea: The most popular view is that an object is a truthmaker if the object couldn't exist and the truth be false. But contingent predications are also held to need truthmakers. Socrates is not necessarily snub-nosed, so a trope or state of affairs is needed. | |
From: Ross P. Cameron (Intrinsic and Extrinsic Properties [2009], 'Truthmakers') | |
A reaction: Cameron calls this 'some heavy ontological commitments'. If snub-nosedness is necessitated by the trope of 'being snub-nosed', what is the truthmaker for Socrates having that trope? |
19489 | For me, fictions are internally true, without a significant internal or external truth-value [Yablo] |
Full Idea: A 'myth' or fiction for me is a true internal statement (a statement endorsed by the rules) whose external truth value is as may be, the point being that that truth value is from an internal standpoint quite irrelevant. | |
From: Stephen Yablo (Does Ontology Rest on a Mistake? [1998], IX) | |
A reaction: This contrasts with Carnap, for whom talk of 'ghosts' is false in an internal thing-framework. Yablo seems here to say a statement can be true while having no truth value. Presumably he is relaxing the internal rules. |
19490 | Make-believe can help us to reason about facts and scientific procedures [Yablo] |
Full Idea: Make-believe games can make it easier to reason about facts, to systematize them, to visualize them, to spot connections with other facts, and to evaluate potential lines of research. | |
From: Stephen Yablo (Does Ontology Rest on a Mistake? [1998], XI) | |
A reaction: This is the key pragmatic defence of the fictionalist view of abstract objects. Fictions are devices to help us think better. I think a lot of ontology turns out that way. |
19491 | 'The clouds are angry' can only mean '...if one were attributing emotions to clouds' [Yablo] |
Full Idea: It is an open question whether the clouds that we call 'angry' are literally F, for any F other than 'such that it would be natural and proper to regard them as angry if one were going to attribute emotions to clouds'. | |
From: Stephen Yablo (Does Ontology Rest on a Mistake? [1998], XII) | |
A reaction: His point is that it is TRUE, in those circumstances, that the clouds are angry. Thus fictions are a valid and useful part of ordinary sensible course, giving real information. I like it. |
15401 | Essentialists say intrinsic properties arise from what the thing is, irrespective of surroundings [Cameron] |
Full Idea: The essentialist approach would be to say that an intrinsic property is one such that it is no part of what it is to instantiate that property that the bearer stands in some relation to its surroundings. | |
From: Ross P. Cameron (Intrinsic and Extrinsic Properties [2009], 'Analysis') | |
A reaction: This is offered as an alternative to the David Lewis account in terms of duplicates across possible worlds. You will have gathered by now, if you have spent days poring over my stuff, that I favour the essentialist approach. |
15393 | An object's intrinsic properties are had in virtue of how it is, independently [Cameron] |
Full Idea: Intrinsic properties are those that an object has solely in virtue of how it is, independently of its surroundings. | |
From: Ross P. Cameron (Intrinsic and Extrinsic Properties [2009], 'Intro') | |
A reaction: Better not mention quantum mechanics and fields if you want to talk of objects being independent of their surroundings. Am I 'independent' of gravity, or is gravity 'independent' of me? |
15396 | Most criteria for identity over time seem to leave two later objects identical to the earlier one [Cameron] |
Full Idea: Criteria for identity across times have proven hard to give. Whatever criteria we lay down, it seems that there are possible situations in which two later objects bear the relevant relation to one earlier object, though only one of them can be identical. | |
From: Ross P. Cameron (Intrinsic and Extrinsic Properties [2009], 'Personal') | |
A reaction: We only have to think of twins, amoebae that fission, and the Ship of Theseus. We seem to end up inventing a dubious criterion in order to break the tie. |
7829 | God no more has human perfections than we have animal perfections [Spinoza] |
Full Idea: To ascribe to God those attributes which make a man perfect would be as wrong as to ascribe to a man the attributes that make perfect an elephant or an ass. | |
From: Baruch de Spinoza (Letters to Blijenburgh [1665], 1665), quoted by Matthew Stewart - The Courtier and the Heretic Ch.10 | |
A reaction: This would be a difficulty for Aquinas's Fourth Way (Idea 1432), and one which I think Aquinas might acknowledge, given his desire that we should be humble when trying to comprehend God (Idea 1410). It leaves us struggling to grasp the concept of God. |
7830 | A talking triangle would say God is triangular [Spinoza] |
Full Idea: If a triangle could speak it would say that God is eminently triangular. | |
From: Baruch de Spinoza (Letters to Blijenburgh [1665], 1665), quoted by Matthew Stewart - The Courtier and the Heretic Ch.10 | |
A reaction: Spinoza had a rather appealing waspish wit. This nicely dramatises an ancient idea (Idea 407). You can, of course, if you believe in God, infer some of His characteristics from His creation. But then see Hume: Ideas 1439, 6960, 6967, 1440. |
