[opposing the claim that all truths have truthmakers]

15 ideas
Saying truths fit experience adds nothing to truth; nothing makes sentences true [Davidson]
     Full Idea: The notion of fitting the totality of experience ...adds nothing intelligible to the simple concept of being true. ....Nothing, ...no thing, makes sentences and theories true: not experience, not surface irritations, not the world.
     From: Donald Davidson (The Very Idea of a Conceptual Scheme [1974], p.11), quoted by Willard Quine - On the Very Idea of a Third Dogma p.39
     A reaction: If you don't have a concept of what normally makes a sentence true, I don't see how you go about distinguishing what is true from what is false. You can't just examine the sentence to see if it has the 'primitive' property of truth. Holism is involved....
Slingshot Argument: seems to prove that all sentences have the same truth-maker [Oliver]
     Full Idea: Slingshot Argument: if truth-makers work for equivalent sentences and co-referring substitute sentences, then if 'the numbers + S1 = the numbers' has a truth-maker, then 'the numbers + S2 = the numbers' will have the same truth-maker.
     From: Alex Oliver (The Metaphysics of Properties [1996], §24)
     A reaction: [compressed] Hence every sentence has the same truth-maker! Truth-maker fans must challenge one of the premises.
Which toothbrush is the truthmaker for 'buy one, get one free'? [Sorensen]
     Full Idea: If I buy two toothbrushes on a 'buy one, get one free' offer, which one did I buy and which one did I get free? Those who believe that each contingent truth has a truthmaker are forced to believe that 'buy one, get one free' is false.
     From: Roy Sorensen (Vagueness and Contradiction [2001], 11.6)
     A reaction: Nice. There really is no fact of which toothbrush is the free one. The underlying proposition must presumably be 'two for the price of one'. But you could hardly fault the first slogan under the Trades Descriptions Act.
Truthmaker has problems with generalisation, non-existence claims, and property instantiations [Crisp,TM]
     Full Idea: Truthmaker is controversial: what of truths like 'all ravens are black', or 'there are no unicorns'. And 'John is tall' is not made true by John or the property of being tall, but by the fusion of the two, but what could this non-mereological fusion be?
     From: Thomas M. Crisp (Presentism [2003], 3.4)
     A reaction: A first move is to include modal facts (or possible worlds) among the truthmakers. The unicorns are tricky, and seem to need all of actuality as their truthmaker. I don't see the tallness difficulty. Predication is odd, but so what?
Speculations about non-existent things are not about existent things, so Truthmaker is false [Merricks]
     Full Idea: That 'there might have been a dozen more fundamental particles' is true, but not appropriately about any existing entities or their properties. Since Truthmaker says that all truths are about existing entities, it must be false.
     From: Trenton Merricks (Truth and Ontology [2007], 6.VI)
     A reaction: Since I don't necessarily agree that 'there might have been a dozen more fundamental particles' (see Scientific Essentialism), and I take the disagreement to have some basis, I doubt this idea. What stops 'there could be circular squares' from being true?
I am a truthmaker for 'that a human exists', but is it about me? [Merricks]
     Full Idea: I am a truthmaker for 'that a human exists', but it is not obvious that that proposition is thus about me.
     From: Trenton Merricks (Truth and Ontology [2007], 7.I)
     A reaction: This is part of the general rather good objection that it is often unclear what a truth is 'about' (Idea 14408). The original Gettier examples about justification illustrate this problem. They make things true, in a surprising way.
'Mickey Mouse is a fictional mouse' is true without a truthmaker [Azzouni]
     Full Idea: 'Mickey Mouse is a fictional mouse' can be taken as true without have any truthmaker.
     From: Jody Azzouni (Deflating Existential Consequence [2004], Ch.3)
     A reaction: There might be an equivocation over 'true' here. 'What, really really true that he IS a fictional mouse?'
Does 'this sentence has no truth-maker' have a truth-maker? Reductio suggests it can't have [MacBride]
     Full Idea: If the sentence 'This sentence has no truth-maker' has a truth-maker, then it must be true. But then what it says must be the case, so it has no truth-maker. Hence by reductio the sentence has no truth-maker.
     From: Fraser MacBride (Truthmakers [2013], 2.1.1)
     A reaction: [Argument proposed by Peter Milne 2005] Rodriguez-Pereyra replies that the sentence is meaningless, so that it can't possibly be true. The Liar sentence is also said to be meaningless. The argument opposes Maximalism.
Even idealists could accept truthmakers, as mind-dependent [MacBride]
     Full Idea: Even an idealist could accept that there are truth-makers whilst thinking of them as mind-dependent entities.
     From: Fraser MacBride (Truthmakers [2013], 3.1)
     A reaction: This undercuts anyone (me, perhaps?) who was hoping to prop up their robust realism with an angry demand to be shown the truthmakers.
Maybe 'makes true' is not an active verb, but just a formal connective like 'because'? [MacBride]
     Full Idea: Maybe the truth-maker panegyrists have misconstrued the logical form of 'makes true'. They have taken it to be a verb like 'x hits y', when really it is akin to the connective '→' or 'because'.
     From: Fraser MacBride (Truthmakers [2013], 3.7)
     A reaction: [He cites Melia 2005] This isn't any sort of refutation of truth-making, but an offer of how to think of the phenomenon if you reject the big principle. I like truth-making, but resist the 'makes' that brings unthought propositions into existence.
Truthmaker talk of 'something' making sentences true, which presupposes objectual quantification [MacBride]
     Full Idea: When supporters of truth-making talk of 'something' which makes a sentence true, they make the assumption that it is an objectual quantifier in name position.
     From: Fraser MacBride (Truthmakers [2013], 3.8)
     A reaction: We might say, more concisely, that they are 'reifying' the something. This makes it sound as if Armstrong and Bigelow have made a mistake, but that are simply asserting that this particular quantification is indeed objectual.
Truthmakers for existence is fine; otherwise maybe restrict it to synthetic truths? [Liggins]
     Full Idea: Many philosophers agree that true existential propositions have a truth-maker, but some go further, claiming that every true proposition has a truth-maker. More cautious theorists specify a class of truths, such as synthetic propositions.
     From: David Liggins (Truth-makers and dependence [2012], 10.1)
     A reaction: [compressed; Armstrong is the ambitious one, and Rodriguez-Pereyra proposes the synthetic propositions] Presumably synthetic propositions can make negative assertions, which are problematic for truth-makers.
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.
What is the truthmaker for a possible new power? [Tallant]
     Full Idea: What power will make true 'there could be a power that does not in fact exist'?
     From: Jonathan Tallant (Metaphysics: an introduction [2011], 04.13)
     A reaction: Nice question. We can't know whether it is true that a new power could exist, so we can't expect an actual truthmaker for it. Though we might predict new powers (such as for a new transuranic element), on the basis of the known ones.
For idealists reality is like a collection of beliefs, so truths and truthmakers are not distinct [Young,JO]
     Full Idea: Idealists do not believe that there is an ontological distinction between beliefs and what makes beliefs true. From their perspective, reality is something like a collection of beliefs.
     From: James O. Young (The Coherence Theory of Truth [2013], §2.1)
     A reaction: This doesn't seem to me to wholly reject truthmakers, since beliefs can still be truthmakers for one another. This is something like Davidson's view, that only beliefs can justify other beliefs.
