We don’t need no explanation

Explanation has played myriad roles in truthmaker theory. The notion of explanation is sometimes thought to give content to the very idea of truthmaking, and is sometimes used as a weapon to undermine the entire point of truthmaker theory. I argue that the notion of explanation is dialectically useless in truthmaker theory: while it’s true that truthmaking offers a form of explanation, this claim is theoretically unilluminating, and leaves truthmaker theorists vulnerable to various kinds of attack. I advocate an alternative approach to truthmaker theory that downplays the role of explanation, and show how it releases the enterprise from a variety of problematic commitments that have troubled truthmaker theorists. The “ontology-first” approach to truthmaking that I advocate not only restores the initial impulse behind truthmaking, but also has a number of theoretical advantages. Most prominently, it dodges the infamous problem of negative existentials, and lessens truthmaker theory’s dependence on contentious intuitive judgments about both explanation and truthmaking

Run Aground: Kit Fine’s Critique of Truthmaker Theory

Kit Fine, the leading proponent of the metaphysical project of grounding theory, has offered a number of potentially devastating objections to truthmaker theory, the branch of metaphysics dedicated to exploring the ontological grounds for truths. In this paper I show what presuppositions about truthmaker theory Fine’s objections are based upon, and why they are false. I discuss four objections that Fine raises, and demonstrate how truthmaker theorists may respond to them. I then showcase the positive contribution that truthmaker theory can make to metaphysics, including its ability to speak to a core metaphysical topic (the ontological grounds for truths) that Fine’s approach to grounding must ultimately remain silent on. I conclude by exploring what I take to be the best option when it comes to understanding how truthmaking and grounding fit together

A unified theory of truth and reference

The truthmaker theory rests on the thesis that the link between a true judgment and that in the world to which it corresponds is not a one-to-one but rather a one-to-many relation. An analogous thesis in relation to the link between a singular term and that in the world to which it refers is already widely accepted. This is the thesis to the effect that singular reference is marked by vagueness of a sort that is best understood in supervaluationist terms. In what follows we show that the supervaluationist approach to singular reference, when wedded to the truthmaker idea, yields a framework of surprising power, which offers a uniform set of solutions to a range of problems regarding identity, reference and knowledge, problems which have hitherto been dealt with on an ad hoc basis

Ideology, Truthmaking and Fundamentality

In chapter 1 I outline two conceptions of ideology: ideological pessimism and ideological realism. Ideological pessimism is the view that ideological inquiry has dim prospects insofar as ideology is tied to meaning. Ideological realism is the view that there is a fact of the matter about which ideology is taken as primitive when attempting to describe reality correctly. I respond to an argument on behalf of ideological pessimism, develop ideological realism, and then defend it against an objection that attempts to derive the unpalatable consequence that a main dispute in the metaphysics of properties is verbal. In chapter 2 I argue that we should uphold the traditional understanding of the ideology/ontology distinction in light of ideological realism. I then argue against the doctrine that certain disputes about composition have the epistemic consequence of providing no grounds for us to believe in one theory over another. In chapter 3 I argue that truthmakers do not necessitate the truths they make true. They either grounds their truths or make true their truths and nothing else can be said about the connection between truth and reality. It is to be taken as primitive that truthmakers make true the truths they make true. In chapter 4 I explore two versions of truthmaking as a theory of fundamentality. I argue against the first and defend the second against various objections and problems. I argue that if we adopt truthmaking as a theory of fundamentality, then we should believe in the second version

Non-Pickwickian Belief and 'the Gettier Problem'

That in Gettier's alleged counterexamples to the traditional analysis of knowledge as justified true belief the belief condition is satisfied has rarely been questioned. Yet there is reason to doubt that a rational person would come to believe what Gettier's protagonists are said to believe in the way they are said to have come to believe it. If they would not, the examples are not counter-examples to the traditional analysis. I go on to discuss a number of examples inspired by Gettier's and argue that they, too, fail to be counter-examples either for reasons similar to those I have urged or because it is not clear that their subject does not know

The Truthmaker Solution to the Gettier Problems

A truthmaker solution to the Gettier problems is based on the idea that knowledge can be defined as justified true belief provided that the source of one’s justification is suitably connected with what makes the believed proposition true. Different developments of this basic intuition have been recently criticized on the basis of a series of arguments aiming at showing that no truthmaker theory can allow us to solve Gettier problems, since the very idea underlying such solution is ineffective. In this paper, I discuss the criticism to the truthmaker solution I consider most promising and show how it can be successfully addressed

Realism, Truthmakers, and Language: A study in meta-ontology and the relationship between language and metaphysics

Metaphysics has had a long history of debate over its viability, and substantivity. This thesis explores issues connected to the realism question within the domain of metaphysics, ultimately aiming to defend a realist, substantive metaphysics by responding to so-called deflationary approaches, which have become prominent, and well supported within the recent metametaphysical and metaontological literature. To this end, I begin by examining the changing nature of the realism question. I argue that characterising realism and anti-realism through theories of truth unduly places epistemology prior to ontology, and is unwarranted in assuming a non-neutrality between theories of truth and positions within the realism debate. I therefore propose a characterisation of realism and anti-realism understood through truthmaking. This produces a suitable working characterisation of realism that will be used within the remainder of this project. In the second section, I trace the historical influences upon current deflationary approaches to metaphysics, most prominently those of Carnap, and Putnam. I argue that Quine’s supposed attack on Carnap’s anti-metaphysical thought fails, and show how current deflationary thought, most prominently exhibited by Hirsch, came to focus on linguistically derived concerns over the substantivity of metaphysics. In the third section, I outline a number of issues for the deflationist, and defend the coherency and legitimacy of the unrestricted existential quantifier. Focusing on the linguistic aspect of deflationism, I argue that the conception of language that the deflationist relies upon lacks suitable empirical and theoretical support within linguistics and other related domains. Furthermore, I suggest that linguistic analysis in fact supports the claim that the quantifier carries no inherent restrictions. This restores our ability to suitably posit the unrestricted existential quantifier, as a quantifier wherein the domain is only restricted by metaphysically substantive restrictions. Through this, I argue that metaphysics is a substantive domain of discourse. Lastly, I sketch a positive account of how, under an empirically and theoretically justified conception of language, metaphysics can be coherently held to be a realist, substantive enterprise, contra claims that hold that the nature of language inherently prevents metaphysics being considered to be a substantive domain of discourse

Essentialism and Absolute Necessity

Bob Hale has argued that logical necessity is absolute necessity. Furthermore, he presents a challenge to the essentialist who tries to evade the consequences of his argument. Here I examine the direct argument he presents for his thesis. I argue that it presents no problem for the essentialist because (1) it begs the question and (2) it relies upon premises that are not entailed by essentialism. I then proceed to show how the essentialist can meet Hale’s challenge

Attitudinal Objects

This paper defends the view that attitudinal objects such as claims, beliefs, judgments, and requests form an ontological category of its own sharply distinguished from that of events and states and that of propositions. Attitudinal objects play a central role in attitude reports and avoid the conceptual and empirical problems for propositions. Unlike the latter, attitudinal objects bear a particular connection to normativity. The paper will also discuss the syntactic basis of a semantics of attitude reports based on attitudinal objects
