This chapter sketches an argument from the metaphysics of possibility to the existence of something that looks very like God. The argument concerns what is called broadly logical, metaphysical, or absolute possibility. The argument begins by contending that the best theory of this places the truth-makers of absolute possibility claims in the powers of actual existing concrete things: this, it contends, provides the most parsimonious metaphysics of possibility. It shows this inter alia by quick comparison with Meinongian, Platonist and David Lewis’ views. The argument leads to something resembling God: an omnipotent, necessarily existing rational agent. The chapter outlines three factors that lead one to ascribe a mind to this necessary being. It would be less strange to us if it had a mind. This provides the overall most adequate “powers” theory of possibility. And it alone seems to let this being provide the possibility that other beings act with libertarian freedom.

Special Case

AbstractThe classical conception of God is that of a necessary being. On a possible worlds semantics, this entails that God exists at every possible world. According to the modal realist account of David Lewis, possible worlds are understood to be real, concrete worlds – no different in kind from the actual world. But, modal realism is equipped to accommodate the existence of a necessary being in only one of three ways: (1) By way of counterpart theory, or (2) by way of a special case of trans-world identity for causally inert necessary beings (e.g. pure sets), or else (3) causally potent ones which lack accidental intrinsic properties. I argue that each of these three options entails unacceptable consequences – (1) and (2) are incompatible with theism, and (3) is incompatible with modal realism. I conclude that (at least) one of these views is false.

Grace and Freedom addresses the issue of divine grace in relation to the freedom of the will in Reformed or “Calvinist” theology in the late sixteenth and early seventeenth century with a focus on the work of the English Reformed theologian William Perkins, and his role as an apologist of the Church of England, defending its theology against Roman Catholic polemic, and specifically against the charge that Reformed theology denies human free choice. Perkins and his contemporaries affirmed that salvation occurs by grace alone and that God is the ultimate cause of all things, but they also insisted on the freedom of the human will and specifically the freedom of choice in a way that does not conform to modern notions of libertarian freedom or compatibilism. In developing this position, Perkins drew on the thought of various Reformers such as Peter Martyr Vermigli and Zacharias Ursinus, on the nuanced positions of medieval scholastics, and on several contemporary Roman Catholic representatives of the so-called second scholasticism. His work was a major contribution to early modern Reformed thought both in England and on the continent. His influence in England extended both to the Reformed heritage of the Church of England and to English Puritanism. On the Continent, his work contributed to the main lines of Reformed orthodoxy and to the piety of the Dutch Second Reformation.

Detailed Presentation

Why care whether there is a necessary being? The chapter opens with an explanation of how the question of whether there is a necessary being matters in theology, cosmology, and debates about fundamental ontology. It is shown that some of the most important questions in these fields depend in one way or another on whether there is a necessary being. Some reason is provided to be optimistic that it is possible to make progress on the question of whether there is a necessary being. Toward that end, the results of a survey (www.necessarybeing.com) are also given, which suggests that the vast majority of people, including skeptics of a necessary being, are inclined to find plausible certain premises in deductive arguments for the existence of a necessary being. The stage is set for a detailed presentation and analysis of those arguments.

The Universe

A necessary being is a concrete entity that cannot fail to exist. An example of such a being might be the God of classical theism or the universe of necessitarians. Necessary Existence offers and carefully defends a number of novel arguments for the thesis that there exists at least one necessary being, while inviting the reader to a future investigation of what the neccessary being(s) is (are) like. The arguments include a defense of a classic contingency argument, a series of new modal arguments from possible causes, an argument from abstract objects, and a Gödelian argument from perfections. Furthermore, arguments against the possibility of a necessary being are critically examined. Among these arguments are old and new arguments from conceivability, a subtraction argument, problems with causation, and an argument from parsimony. Necessary Existence also includes a defense of the axioms of S5 modal logic, which is a framework for understanding several arguments for necessary existents.

Fictional Truth

This chapter addresses the complaint that extreme intentionalism standardly forces the reader who engages in interpretation to posit private, or hidden, authorial intentions, for which she has little or no evidence. It is first argued that there are no automatic strategies of interpretation of fictional content: at every stage, whether or not a given interpretative strategy is to be appropriately applied depends on the presence of relevant authorial intention as a sanction. (This section includes a discussion, and rejection, of the views of David Lewis and Gregory Currie about fictional truth; a discussion of the relevance of genre to fictional content; and a consideration of the issue of unreliable narration for an intentionalist view.) The foregoing material on strategies of interpretation is then used to show that it is false to think of the extreme intentionalist as being committed to ‘hidden’ or ‘secret’ meanings in the ordinary case.

Fictional Truth

This book begins with a detailed description and defence of a controversial theory of fictional content (or ‘fictional truth’) known as ‘extreme intentionalism’. On this view, roughly, the fictional content of a particular text is equivalent to exactly what the author of the text intended the reader to imagine. The book situates this theory in relation to its competitors including hypothetical intentionalism, value-maximizing theory, and the influential anti-intentionalism view of David Lewis—and puts forward a strong argument for its superiority, despite its many detractors. In the second half of the book, some consequences of extreme intentionalism are explored as they affect questions such as: the relation of fiction to testimony and belief; whether there are any limits to what we can imagine, and what explains those limits; what is the nature of fiction; to what extent imagination resembles belief; and to what extent the imagination can contribute to the provision of counterfactual and modal knowledge.

Chapter 4 reviews ‘behavioural welfare economics’—the approach to normative analysis that is favoured by most behavioural economists. This approach assumes that people have context-independent ‘true’ or ‘latent’ preferences which, because of psychologically-induced errors, are not always revealed in actual choices. Behavioural welfare economics aims to reconstruct latent preferences by identifying and removing the effects of error on decisions, and to design policies to satisfy those preferences. Its implicit model of human agency is of an ‘inner rational agent’ that interacts with the world through an imperfect psychological ‘shell’. I argue that there is no satisfactory evidence to support this model, and no credible psychological foundation for it. Since the concept of true preference has no empirical content, the idea that such preferences can be reconstructed is a mirage. Normative economics needs to be more radical in giving up rationality assumptions.
