- Philipp Keller (2007). A World of Truthmakers. In Jean-Maurice Monnoyer (ed.), Metaphysics and Truthmakers. Ontos Verlag.I will present and criticise the two theories of truthmaking David Armstrong offers us in Truth and Truthmakers (Armstrong 2004), show to what extent they are incompatible and identify troublemakers for both of them, a notorious – Factualism, the view that the world is a world of states of affairs – and a more recent one – the view that every predication is necessary. Factualism, combined with truthmaker necessitarianism – ‘truthmaking is necessitation’ – leads Armstrong to an all-embracing totality state of affairs that necessitates not only everything that is the case but also everything else – that which is not the case, that which is merely possible or even impossible. All the things so dear to realists – rocks, natural properties, real persons – become mere abstractions from this ontological monster. The view that every predication is necessary does in some sense the opposite: it does away with totality states of affairs and, arguably, also with states of affairs. We have particulars and universals, partially identical and necessarily connected to everything else. Just by the existence of anything, everything is necessitated – the whole world mirrored in every monad. Faced with the choice between these two equally unappealing alternatives, I suggest returning to Armstrong’s more empiricist past: the world is not an all-inclusive One, nor necessitated by every single particular and every single universal, but a plurality of particulars and universals, interconnected by a contingent and internal relation of exemplification. While a close variant, truthmaker essentialism, can perhaps be saved, this means giving up on truthmaker necessitarianism. This, I think, what it takes to steer a clear empiricist course between the Scylla of Spinozist general factness and the Charybdis of a Leibnizian overdose of brute necessities.Reading list | Discuss | Edit | Categorize |My bibliography

Substantial facts (or states of affairs ) are not well-understood entities. Many philosophers object to their existence on this basis. Yet facts, if they can be understood, promise to do a lot of philosophical work: they can be used to construct theories of property possession and truthmaking, for example. Here, I give a formal theory of facts, including negative and logically complex facts. I provide a theory of reduction similar to that of the typed λ -calculus and use it to provide identity conditions for facts. This theory validates truthmaker maximalism : it provides truthmakers for all truths. I then show how the usual truth-in-a-model relation can be replaced by two relations: one between models and facts, saying that a given fact obtains relative to the model, and the other between facts and propositions: the truthmaking relation.

In his criticism of Armstrong’s argument against nominalism, Parsons (1999) makes a crucial use of a notion of truthmaking in terms of weak supervenience which assumedly: (i) does not entail truthmaker essentialism, (ii) is neutral as to the issue of nominalism, and (iii) is useful in Armstrong’s argument against Ryle. I will try to show that Parsons’ notion is defective because it does not preserve the explanatory character of truthmakers. Besides, I argue that the natural reformulation of the notion in terms of strong supervenience fails in two respects: (i) it is not neutral as to the issue of nominalism and (ii) it does not preserve the explanatory character of truthmakers if it succeeds in avoiding truthmaker essentialism. As a corollary, Armstrong’s truthmaker argument against nominalism is vindicated.

When a truth-bearer is true, that is because something or other in the world makes it true. My dissertation offers a theory of truthmakers that shows how we should flesh out this thought while avoiding the contentious metaphysical commitments that are built into other truthmaker theories. Because of these commitments, many philosophers have come to view truthmaker theory as being essentially tied to correspondence theories of truth, and to metaphysical realism. I argue that, quite to the contrary, truthmaker theory is distinct from correspondence theory, and that the former actually undermines the motivation for the latter. In fact, truthmaker theory can be used to argue for a particular kind of deflationism about truth. I also argue that debates about realism and anti-realism are best viewed through the lens of truthmaker theory, which is not—contrary to what many have thought—an essentially realist approach to metaphysics. Anti-realists of various stripes can also make use of truthmakers. The anti-realism of such views depends upon either the nature of the truthmakers they use, or the nature of the truthmaking relation itself.

That is, an object x is a truthmaker for the claim A if x exists, and the existence of x necessitates the truth of A. In symbols: E!x ∧ (E!x ⇒ A). I argued in my paper “Truthmakers, Entailment and Necessity” [14], that if we wish to use this account of truthmaking, we ought understand the entailment connective “⇒” in such a claim as a relevant entailment, in the tradition..

The idea of truthmakers is important for doing serious metaphysics, since a truthmaker principle can give us important guidance in finding out what we would like to include into our ontology. Recently, David Lewis has argued against Armstrong’s argument that a plausible truthmaker principle requires us to accept facts. I would like to take a close look at the argument. I will argue in detail that the Humean principle of recombination on which Lewis relies is not plausible (independently of the issue of facts). Then I will show that the right truthmaker principle that vindicates facts is superior to the modified truthmaker principle that Lewis has proposed. This will lead into the topic of being and existence. It turns out that truthmaking and facts are plausible, well suited for one another, and very coherent with a plausible conception of being.

On the truthmaker view of ontological commitment [Heil (From an ontological point of view, 2003); Armstrong (Truth and truthmakers, 2004); Cameron (Philosophical Studies, 2008)], a theory is committed to the entities needed in the world for the theory to be made true. I argue that this view puts truthmaking to the wrong task. None of the leading accounts of truthmaking—via necessitation, supervenience, or grounding—can provide a viable measure of ontological commitment. But the grounding account does provide a needed constraint on what is fundamental. So I conclude that truthmaker commitments are not a rival to quantifier commitments, but a needed complement. The quantifier commitments are what a theory says exists, while the truthmaker commitments are what a theory says is fundamental.

For many assertions, the correspondence theory of truth seems intuitively to give the best account of the difference between truth and falsity, but one of its problems is how to explicate the notions of “correspondence” and “truthmaking”. In conformity with the view of David Armstrong, it is claimed that truthmaking is an internal relation between a truthmaker and a truth(-value-)bearer. The truthbearer (a token proposition) can exist without the truthmaker (an object or a state of affairs), and vice versa, but when both exist the truthmaker necessarily makes the truthbearer true and correspondence obtains. Contrary to Armstrong’s reductionist analyses of internal relations and propositions, however, it is argued that internal relations can have a mind-independent existence and “add to being”, that truthbearers and truthmakers are categorially different, and that the correspondence theory of truth requires a distinction between internal relations with heterogeneous and homogeneous relata, respectively.

Armstrong has defended a version of 'truthmaker necessitarianism', the doctrine that truths necessitate truthmakers. Truthmaker necessitarianism, he contends, requires the postulation of 'totality facts', which serve as ingredients of truthmakers for general truths and negative truths, and propositions, which function as the fundamental truth bearers. I argue that neither totality facts nor propositions need figure in an account of truthmaking, and suggest that both are artifacts stemming, albeit in different ways, from an ontologically shady 'linguisticizing' tendency to conflate features of descriptions and features of what is described.

Truthmaker theory promises to do some useful philosophical work: equipping us to argue against phenomenalism and Rylean behaviourism, for instance, and helping us decide what exists (Lewis 1999, 207; Armstrong 1997, 113-119). But it has proved hard to formulate a truthmaker theory that is both useful and believable. I want to suggest that a neglected approach to truthmakers – that of Ian McFetridge – can surmount some of the problems that make other theories of truthmaking unattractive. To begin with, I’ll outline some of the most prominent accounts of truthmaking in the current literature. Then the second part of the paper will explain McFetridge’s theory and argue for its superiority over these accounts.
