This book, first published in 2004, makes a compelling case for truthmaking and its importance in philosophy.

The concept of truthmaking is attracting much attention in contemporary metaphysics. This work asks how the truthmaker principle should be formulated, whether it is well motivated, whether it genuinely has the explanatory roles claimed for it, and whether more modest principles might serve just as well.

Demonstrates how truthmaking can be used to make progress all across philosophy, but without its usual theoretical baggage.

Mark Jago offers a new metaphysical account of truth. He argues that to be true is to be made true by the existence of a suitable worldly entity. Truth arises as a relation between a proposition - the content of our sayings, thoughts, beliefs, and so on - and an entity (or entities) in the world.

Truth depends in some sense on reality. But it is a rather delicate matter to spell this intuition out in a plausible and precise way. According to the theory of truth-making this intuition implies that either every truth or at least every truth of a certain class of truths has a so-called truth-maker, an entity whose existence accounts for truth. This book aims to provide several ways of assessing the correctness of this controversial claim. This book presents a detailed introduction to the theory of truth-making, which outlines truth-maker relations, the ontological category of truth-making entities, and the scope of a truth-maker theory. The essays brought together here represent the most important articles on truth-making in the last three decades as well as new essays by leading researchers in the field of the theory of truth and of truth-making.

That there are no white ravens is true because there are no white ravens. And so there is a sense in which that truth 'depends on the world'. But this sort of dependence is trivial. After all, it does not imply that there is anything that is that truth's 'truthmaker'. Nor does it imply that something exists to which that truth corresponds. Nor does it imply that there are properties whose exemplification grounds that truth. Trenton Merricks explores whether and how truth depends substantively on the world or on things or on being. And he takes a careful look at philosophical debates concerning, among other things, modality, time, and dispositions. He looks at these debates because any account of truth's substantive dependence on being has implications for them. And these debates likewise have implications for how and whether truth depends on being. Along the way, Merricks makes a number of new points about each of these debates that are of independent interest, of interest apart from the question of truth's dependence on being. Truth and Ontology concludes that some truths do not depend on being in any substantive way at all. One result of this conclusion is that it is a mistake to oppose a philosophical theory merely because it violates truth's alleged substantive dependence on being. Another result is that the correspondence theory of truth is false and, more generally, that truth itself is not a relation of any sort between truth-bearers and that which 'makes them true'.

How do we explain the truth of true propositions? Truthmaker theory is the branch of metaphysics that explores the relationships between what is true and what exists. It plays an important role in contemporary debates about the nature of metaphysics and metaphysical enquiry. In this book Jonathan Tallant argues, controversially, that we should reject truthmaker theory. In its place he argues for an 'explanationist' approach. Drawing on a deflationary theory of truth he shows that it allows us to explain the truth of true propositions and respond to recent arguments that purport to show otherwise. He augments this with a distinction between internally and externally quantified claims: externally quantified claims are claims that quantify over elements of our ontology that play an indispensable explanatory role; internally quantified claims do not. He deploys this union of deflationism and a distinction between kinds of quantification to pursue metaphysical inquiry, sketching the implications for a number of first-order debates, including those in the philosophy of time, modality and mathematics, and also shows how this explanationist model can be used to solve the key problems that afflicted truthmaker theory. Truth and the World is an important contribution to debates about truth and truthmaker theory as well as metametaphysics, the metaphysics of time and the metaphysics of mathematics, and is essential reading for students and scholars engaged in the study of these topics.
