In this paper I examine two principles of orthodox truthmaker theory: truthmaker maximalism - the doctrine that every (contingent) truth has a truthmaker, and truthmaker necessitarianism - the doctrine that the existence of a truthmaker necessitates the truth of any proposition which it in fact makes true. I argue that maximalism should be rejected and that once it is we only have reason to hold a restricted form of necessitarianism.

During the realist revival in the early years of this century, philosophers of various persuasions were concerned to investigate the ontology of truth. That is, whether or not they viewed truth as a correspondence, they were interested in the extent to which one needed to assume the existence of entities serving some role in accounting for the truth of sentences. Certain of these entities, such as the Sätze an sich of Bolzano, the Gedanken of Frege, or the propositions of Russell (...) and Moore, were conceived as the bearers of the properties of truth and falsehood. Some thinkers however, such as Russell, Wittgenstein in the Tractatus, and Husserl in the Logische Untersuchungen, argued that instead of, or in addition to, truth-bearers, one must assume the existence of certain entities in virtue of which sentences and/or propositions are true. Various names were used for these entities, notably 'fact', 'Sachverhalt', and 'state of affairs'. (1) In order not to prejudge the suitability of these words we shall initially employ a more neutral terminology, calling any entities which are candidates for this role truth-makers. (shrink)

I argue that the one and only truthmaker is the world. This view can be seen as arisingfrom (i) the view that truthmaking is a relation of grounding holding between true propositions and fundamental entities, together with (ii) the view that the world is the one and only fundamental entity. I argue that this view provides an elegant and economical account of the truthmakers, while solving the problem of negative existentials, in a way that proves ontologically revealing.

This bulletin contains a summary of the main topics of discussion in truthmaker theory, namely: the definition of truthmakers, problems with Truthmaker Necessitarianism and Truthmaker Maximalism, the ontological burden of truthmakers and the recalcitrant topic of truthmakers for negative truths.

Arriaga is an early modern scholastic who recognizes the importance of relations to philosophical discussions. He offers a classification of different kinds of relations, focusing on the distinction between categorial relations and transcendental relations. I suggest that this distinction might be seen as akin to one version of the modern distinction between external and internal relations. Like Suárez, whom he characterizes as a “giant among the scholastics,” Arriaga offers a reductionist account of categorial relations. He criticises Suárez’s account, however, for (...) formally identifying a relation with the foundation in one relatum, something Suárez does in order to preserve a real distinction between converse relations. Arriaga, in contrast, argues that a categorial relation is formally identical to the foundation and terminus. Arriaga gives less attention to transcendental relations, even though he thinks they are real relations, but I offer some suggestions for how he may be thinking about them. (shrink)

Truths are determined not by what we believe, but by the way the world is. Or so realists about truth believe. Philosophers call such theories correspondence theories of truth. Truthmaking theory, which now has many adherents among contemporary philosophers, is the most recent development of a realist theory of truth, and in this book D. M. Armstrong offers the first full-length study of this theory. He examines its applications to different sorts of truth, including contingent truths, modal truths, truths about (...) the past and the future, and mathematical truths. In a clear, even-handed and non-technical discussion he makes a compelling case for truthmaking and its importance in philosophy. His book marks a significant contribution to the debate and will be of interest to a wide range of readers working in analytical philosophy. (shrink)

Challenging the myth that mathematical objects can be defined into existence, Bigelow here employs Armstrong's metaphysical materialism to cast new light on mathematics. He identifies natural, real, and imaginary numbers and sets with specified physical properties and relations and, by so doing, draws mathematics back from its sterile, abstract exile into the midst of the physical world.

I present a puzzle concerning counterfactual reasoning and argue that it should be solved by giving up the principle of substitution for logical equivalents.

Seventeenth century scholastics had a rich debate about the ontological status and nature of lacks, negations, and privations. Realists in this debate posit irreducible negative entities responsible for the non-existence of positive entities. One of the first scholastics to develop a realist position on negative entities was Thomas Compton Carleton. In this paper I explain Carleton's theory of negative entities, including what it is for something to be negative, how negative entities are individuated, whether they are abstract or concrete, and (...) how they affect their subjects. I argue that for Carleton, negative entities are conceived as spatially extended simples that affect their subjects by means of spatial overlap. I also show how Carleton responds to some theological worries about his realism concerning negative entities. (shrink)

This book argues that correspondence theories of truth fail because the relation that holds between a true thought and a fact is that of identity, not correspondence. Facts are not complexes of worldly entities which make thoughts true they are merely true thoughts. According to Julian Dodd, the resulting modest identity theory, while not defining truth, correctly diagnoses the failure of correspondence theories, and thereby prepares the ground for a defensible deflation of the concept of truth.

This volume will be the starting point for future discussion and research.

What does reality encompass? Is it exclusively physical, or does it include mental and 'abstract' aspects? What are the elements of being, reality's raw materials? John Heil offers stimulating answers to these questions framed in terms of a comprehensive metaphysics of substances and properties inspired by Descartes, Locke, and their successors.

Prima facie it seems easy to understand what he had in mind when he spoke of accidental being and being as true. Accidental or incidental being, what the Latins would later call ens per accidens, was in fact a juxtaposition of two or more categorical beings. As such it lacked a unified essence and thus it lacked genuine being. It was being "only in name." Being as true, he told us, was in the synthesis of the intellect, that is, the (...) intellect's second operation of judgment. Apparently, it was the being of the copula "is" in a true judgment. Contrasted with this was being as false, or pseudo-being, which strictly is nonbeing, found in the copula of a false judgment. (shrink)

Truth and Ontology concludes that some truths do not depend on being in any substantive way at all.

Beings of reason present metaphysicians with an interesting dilemma—they can be thought about even though there are no such things; yet to be thought about it would seem that they must have some kind of being. In this essay it is argued that Suárez presented a sophisticated alternative to Meinongism that is absent from contemporary discussions of beings of reason. Suárez’s doctrine is analysed in terms of ‘tethered counterfactuals’—they are tethered because they and their being are tied to acts of (...) intellection and counterfactual because the intellect treats them as if they existed even though they do not.
