The paper argues against a commitment to metaphysical necessity, semantic modalities are enough. The best approaches to elucidate the semantic modalities are (still) versions of lingustic ersatzism and fictionalism, even if only developed in parts. Within these necessary properties and the difference between natural and semantic laws can be accounted for. The proper background theory for this is an updated version of Logical Empiricism, which is congenial to recent trends in Structural Realism. The anti-metaphysical attitude of Logical (...) Empiricism deserves revitalization. Another target besides metaphysical necessity are substantial forms of iterated modalities, as used, for instance, in the philosophy of religion. (shrink)

In this collection of essays, Franklin I. Gamwell offers a defense of transcendental metaphysics, especially in its neoclassical form, and builds a case for its importance as a tool for addressing abiding problems in morality and philosophical theology-including talk about God, human fault, moral decision, and the relationship of politics and religious freedom. In Part I, Gamwell argues against Kant and a wide range of contemporary philosophers, for the validity of transcendental metaphysics designated in the strict sense, i.e., as an (...) explication of the possible as such or existence as such, as the most general features or conditions all possible things have in common. He engages with Aquinas, Schleiermacher, Augustine, and Niebuhr to argue that neoclassical metaphysics, for which the divine whole is itself temporal or forever self-surpassing, provides a more coherent account of God than does classical metaphysics, for which the divine whole is completely eternal. In Part II, Gamwell looks at transcendental metaphysics designated in the broad sense, i.e., as an explication of possible subjectivity as such, as the most general features or conditions all possible subjects have in common. In particular, he takes up the moral opportunity that humans are presented with, and argues that the moral law depends on a comprehensive good, that is, a good defined metaphysically in the strict sense. He then offers an extended discussion of the relation between transcendental metaphysics (in the broad sense) and the meaning of religious freedom and explores Ronald Dworkin's view of the relationship between democracy and religion, the question of whether religious activities are properly exempted from generally applicable laws, and the constitutional debate about national and states' rights.

A lot of philosophers engage in debates about what claims are “metaphysically necessary”, and a lot more assume with little argument that some classes of claims have the status of “metaphysical necessity”. I think we can usefully replace questions about metaphysical necessity with five other questions which each capture some of what people may have had in mind when talking about metaphysical necessity. This paper explains these five other questions, and then discusses the question (...) “how much of metaphysics is metaphysically necessary?”, and each of its five replacements. (shrink)

Many people hold that there is a distinctive notion of metaphysical necessity. In this paper I explain why I am skeptical about the view. I examine the sorts of considerations that are adduced for it, and argue that they meet equal and opposite considerations.

This paper argues for a certain kind of anti-metaphysicalism about the temporal ontology debate, i.e., the debate between presentists and eternalists over the existence of past and future objects. Three different kinds of anti-metaphysicalism are defined—namely, non-factualism, physical-empiricism, and trivialism. The paper argues for the disjunction of these three views. It is then argued that trivialism is false, so that either non-factualism or physical-empiricism is true. Finally, the paper ends with a discussion of whether we should endorse non-factualism or physical-empiricism. (...) An initial reason is provided for thinking that non-factualism might be true, but in the end, the paper leaves this question open. The paper also argues against a certain kind of necessitarianism about the temporal ontology debate; but this isn't an extra job—the falsity of this necessitarian view falls out of the other arguments as a sort of corollary.

This paper presents an account of the understanding of statements involving metaphysical modality, together with dovetailing theories of their truth conditions and epistemology. The account makes modal truth an objective matter, whilst avoiding both Lewisian modal realism and mind-dependent or expressivist treatments of the truth conditions of modal sentences. The theory proceeds by formulating constraints a world-description must meet if it is to represent a genuine possibility. Modal truth is fixed by the totality of the constraints. To understand modal (...) discourse is to have tacit knowledge of the body of information stated in these constraints. Modal knowledge is attained by evaluating modal statements in accordance with the constraints. The question of the general relations between modal truth and knowability is also addressed. The paper includes a discussion of which modal logic is supported by the presented theory of truth conditions for modal statements. (shrink)

A popular response to the Exclusion Argument for physicalism maintains that mental events depend on their physical bases in such a way that the causation of a physical effect by a mental event and its physical base needn’t generate any problematic form of causal overdetermination, even if mental events are numerically distinct from and irreducible to their physical bases. This paper presents and defends a form of dualism that implements this response by using a dispositional essentialist view of properties to (...) argue that the psychophysical laws linking mental events to their physical bases are metaphysically necessary. I show the advantages of such a position over an alternative form of dualism that merely places more “modal weight” on psychophysical laws than on physical laws. The position is then defended against the objection that it is inconsistent with dualism. Lastly, some suggestions are made as to how dualists might clarify the contribution that mental causes make to their physical effects. (shrink)

Metaphysics, as I understand it, is the attempt to construct theories which give correct accounts in general terms of pervasive structural features of reality. Though not precise and not intended as an explicit definition, this characterization is comprehensive enough to include both descriptive and revisionary varieties of metaphysical theory. The enterprise of descriptive metaphysics, Strawson tells us, consists in describing “the actual structure of our thought about the world.” Presumably a philosopher would favor this approach to metaphysics if he (...) or she believed either that the actual structure of our thought about the world provides, at least for the most part, an accurate portrait of the world’s structure or that the actual structure of our thought at any time provides privileged access, or perhaps our only access, at that time to the structure of the world. Revisionary metaphysics, by contrast, is concerned to produce a structure of thought about the world better than the one we actually have. Obviously a philosopher would adopt this approach if he or she believed that the actual structure of our thought about the world provides, in at least some important respects, an inaccurate portrait of the world’s structure and stands in need of revision in the interests of correctness. And clearly a philosopher might hold that the actual structure of our thought is quite accurate in some respects and need only be described to yield correct theory and yet is thoroughly inaccurate in others and requires substantial revision if correct theory is to be the outcome. Philosophers may, as I suppose most of them do, practice by turns descriptive and revisionary kinds of metaphysics. No global commitment to one approach or the other is required; the choice between approaches can be allowed to rest on the exigencies of local problems. (shrink)

Kripke and putnam have argued that metaphysical necessity is truth in all possible worlds, Hence is a kind of logica necessity; it is this claim I argue against.

I begin by defending condition (i) against five objections (section 2). Following this, I show that the theory that laws obtain contingently encounters three problems that are solved by the theory that laws are metaphysically necessary (section 3). In section 3, I criticize the regularity theory of natural laws and the universals theory of Armstrong, Dretske and Tooley, and also show how the metaphysical theory solves the “inference problem” that Van Fraassen (1989) posed for any theory of natural laws.

To differentiate between the laws of nature and accidental generalizations, we must adopt a view of necessity that is capable of being realized in relationships existing among natural objects. In neo-Sadraian Islamic philosophy, metaphysical necessity is accepted as part of the cause-effect relationship. This paper compares the neo-Sadraian interpretation of necessity and necessitarian theories about the laws of nature, particularly essentialism and universal theory. By resorting to specific forms al-shûrat al-naw’iyyah, the origin of the essential properties (...) of natural objects, I argue that neo-Sadraians have proposed a perspective on metaphysical necessity that is epistemologically a posteriori.

Argues that morals and politics require on a metaphysical backing and proposes a neoclassical metaphysics.

In her 1938 paper ‘Logical and Metaphysical Necessity’, Martha Kneale introduces the necessary a posteriori. I present a critical summary of Kneale's argument that so-called ‘metaphysical propositions’ are necessary but not a priori. I argue that Kneale is well placed to offer a template for reconciling conceivability approaches to modal epistemology with the post-Kripkean trend for taking metaphysical necessities to have their source in mind-independent reality.

I begin by contrasting three approaches one can take to the distinction between the essential and accidental properties: an ontological, a deflationary, and a mind‐dependent approach. I then go on to apply that distinction to the necessary a posteriori, and defend the deflationist view. Finally I apply the distinction to modal truth in general and argue that the deflationist position lets us avoid an otherwise pressing problem for the actualist: the problem of accounting for the source of modal truth.

I argue that a pragmatic scepticism about metaphysical modality is a perfectly reasonable position to maintain. I then illustrate the difficulties and limitations associated with some strategies for defeating such scepticism. These strategies appeal to associations between metaphysical modality and the following: objective probability, counterfactuals and distinctive explanatory value.

I propose a different way of thinking about metaphysical and physical necessity: namely that the fundamental notion of necessity is what would ordinarily be called "truth in all physically possible worlds" – a notion which includes the standard physical necessities and the metaphysical ones as well; I suggest that the latter are marked off not as a stricter kind of necessity but by their epistemic status. One result of this reconceptualization is that the Descartes-Kripke argument (...) against naturalism need no longer trouble us. I end by relating the difference between my view and the standard view to the question, whether there could have been a different world than ours. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Existence and the Good: Metaphysical Necessity in Morals and Politics by Franklin I. GamwellWilliam MeyerExistence and the Good: Metaphysical Necessity in Morals and Politics FRANKLIN I. GAMWELL Albany: State University of New York Press, 2011. 219 pp. $24.95In the current era, a few prominent philosophers have called into question the antiteleological tendencies of modern thought. For instance, Thomas Nagel argues that we should reject (...) the antiteleology of science and its “comprehensive, speculative world picture” of “reductive materialism” (Mind and Cosmos, Oxford 2012, 4). As a nontheist, Nagel proposes a “natural teleology” as a secular alternative to theism and to the nonteleology of science as a way to offer a more intelligible and holistic understanding of existence; yet he admits at one point: “Without God, it is unclear what we should aspire to harmony with” (Secular Philosophy & the Religious Temperament, Oxford 2010, 6). With less notoriety but with greater insight, Franklin Gamwell challenges not only modernity’s nonteleology but also its postmetaphysical outlook. By developing a neoclassical or process form of metaphysical theism informed by the works of Charles Hartshorne and Alfred North Whitehead, Gamwell spells out with thoughtful clarity what we should aspire to harmonize with in our individual and collective lives.Focusing on moral and political theory, Gamwell demonstrates that a coherent understanding of ethics (The Divine Good: Modern Moral Theory and the Necessity of God, HarperSanFrancisco, 1990) and politics (Democracy on Purpose: Justice and the Reality of God, Georgetown University Press, 2000) presupposes a neoclassical metaphysical teleology. Here, in Existence and the Good, he offers [End Page 228] a more concise, refined, and integrated formulation of these previous arguments as well as new engagements with important thinkers such as Martin Heidegger and Jeffrey Stout.Gamwell pursues metaphysics in both a “strict” and a “broad” sense: the former refers to critical reflection on the most general characteristics of existence as such, while the latter refers to reflection on the necessary conditions of existence with understanding (17–19). Beginning with the former, he argues that metaphysics properly conceived––in terms of becoming rather than being––is a valid and essential enterprise because “something exists” is necessarily true while “nothing exists” cannot possibly be true (25). He then seeks to show that metaphysics in a broad sense includes metaphysics in the strict sense because existence with understanding necessarily presupposes a metaphysical telos. Toward this end, he engages Heidegger on the metaphysics of subjectivity (chap. 2). Whereas the later Heidegger maintains that all understandings of totality are wholly dependent upon some lifeworld, Gamwell counters that “totality is prior to meaning” because “exemplifications of subjectivity are constituted by prior or nonconscious relations to an order of actualities and possibilities” (49).In chapter 3 Gamwell explicates his neoclassical theism by arguing that the metaphysical telos must be an all-inclusive divine individual. Distinct from Hartshorne, he posits that God does not relate to the world merely in terms of an integration of all past actualities but rather “cooccupies the locus of all contemporaries.” Thus, all “worldly enactment localizes the divine” (90). Gamwell offers here a metaphysical version of incarnation: “Localization of the divine means relation to a becoming that cooccupies one’s place in the world and, therefore, means a communion unlike any other, so that God, we may say, is ‘closer than hands or feet.’ As the metaphysical individual, God is literally the one ‘in whom we live and move and have our being’” (92).Gamwell concludes by engaging Stout on the underlying necessity of metaphysics for democracy. Whereas Stout offers an “ethics without metaphysics” in the form of a “specific pragmatism,” which holds that citizens can coordinate actions on the basis of “moral norms [that] are entirely creatures of historically located social practices” (134), Gamwell maintains that democracy requires “a metaphysical pragmatism,” because “the practice of democratic discourse itself, as all human practices, implies the necessary principle or principles of morality” (146). The key distinction here is between implicit and explicit: Gamwell submits that democracy implicitly presupposes the divine metaphysical telos because that telos is rooted in the very character of reality as such. However, this does not mean that citizens must explicitly recognize or hold... (shrink)

In this paper, I intend to argue against Alexander Bird‟s thesis (2001) that the law salt dissolves in water is metaphysically necessary. I briefly indicate Bird‟s argument for the necessity of such law, and then I provide a counter-argument to his thesis. In a general way, Bird wants to show that the existence of certain substances depends on the truth of certain laws, and that because of this the existence of such substances implies the existence of such laws. That (...) would make the laws existing at least while the substance it rules exists; what, for Bird, makes such laws metaphysically necessary. My counter-argument to Bird is that such conception apprehends just what we call “weak necessity”, and not the strong necessity we would like a metaphysically necessary law to have. (shrink)

According to Williamson’s epistemology of modality, we know metaphysical necessities by means of our knowledge of some specific counterfactualconditionals. In particular, Williamson’s idea is that we come to have knowledge of metaphysical necessities—which have the form □A—via our knowledge ofcounterfactual conditionals which have the form ~A□→┴. In this paper I claim that there are two different ways in which Williamson’s position can plausibly bearticulated, and that both ways lead to circularity.

Philosophers have observed that metaphysical necessity appears to be a true or real or genuine form of necessity while epistemic necessity does not. Similarly, natural necessity appears genuine while deontic necessity does not. But what is it for a form of necessity to be genuine? I defend an account of genuine necessity in explanatory terms. The genuine forms of necessity, I argue, are those that provide what I call necessitarianexplanation. I discuss (...) the relationship of necessitarian explanation to ground. (shrink)

Let Nomological Bound be the thesis that there is nothing objectively possible beyond what is physically possible. Nomological Bound has struck many as a live hypothesis. Nevertheless, in this article I provide a novel argument against it. Yet even though I claim that Nomological Bound is false, I argue that the boundaries of objective possibility can still be characterized intimately in terms of physical necessity. This is philosophically significant, for on a natural understanding it constitutes the powerful anti-sceptical result (...) that those who believe in physical necessity should not harbour any scepticism towards merely metaphysical possibilities.

In George Nakhnikian’s interesting and stimulating paper, “Quantum Cosmology, Theistic Philosophical Cosmology, and the Existence Question” (present issue) he addresses the fundamental issue of whether it is metaphysically possible or justifiable to believe that our universe began to exist without a cause, divine or otherwise. His conclusion is negative, and he argues that, contrary to my views, quantum cosmology is consistent with theism. In this paper, I shall evaluate Nakhnikian’s arguments.

In his _Being Known_ Peacocke sets himself the task of answering how we come to know about metaphysical necessities. He proposes a semantic principle-based conception consisting of, first, his Principles of Possibility which pro­vide necessary and sufficient conditions for a new concept 'admissibility', and second, characterizations of possibility and of necessity in terms of that new con­cept. I focus on one structural feature; viz. the recursive application involved in the specification of 'admissibility'. After sketching Peacocke’s proposal, I intro­duce (...) a fictional protagonist, Cautious Peacocke, whose coherence I claim shows that Peacocke s proposal cannot be made good.

In this paper I argue against Mark Jago’s recent suggestion that ordinary knowers can move from knowledge of essence to knowledge of metaphysical necessity.

I argue that the account of the epistemic modalities developed by Kripke and Putnam is incomplete since it does not make use of the possible worlds machinery that is indispensable to their analysis of the metaphysical modalities. It would have been simpler and more elegant if they had used the concept of 'possible world' to explain both modalities. Instead, they provide an explication of the epistemic modalities in terms of the vague concepts of conceivability and revisability. I show that (...) logical omniscience as a consequence of a possible worlds analysis of the epistemic modalities can be made palatable. (shrink)

I discuss a short string of five sentences in Metaphysics V.5, 1015b6-9 relating demonstration to necessity. My proposal is that Aristotle focuses his attention on the demonstration as a demonstration. Other interpretations reduce the necessity in question to the modality of the component sentences of the demonstrations (the conclusion and the premises). My view does not deny that the modality of the component sentences is important, but takes seriously the idea that a demonstration itself should be understood as (...) necessary—as not capable of being otherwise. A demonstration cannot be different from what it is in the sense that [i] its components cannot be different from what they are, [ii] its components must be related to each other exactly in the way they are related. Demonstrations aim at the fully appropriate explanation of a given explanandum—and each demonstration is individuated by the explanandum it takes. Thus, the basic idea is that, for the target explanandum that individuates a given demonstration, the premises delivering the fully appropriate explanation cannot be replaces with different ones. I show how this proposal, which explains Aristotle’s language in 1015b6-9 accurately, does not make demonstrations ‘melt down into conditional necessity’, first, because the modality of the component sentences is still importantly involved, second, because the explanatory relation expressed in a demonstration is a necessary fact in the real world, so that the demonstration itself is also necessary (in the way I have explained) inasmuch as it captures that fact.

Finean essentialists take metaphysical necessity to be metaphysically explained by essence. But whence the explanatory power of essence? A recent wave of criticism against the Finean account has put pressure on essentialists to answer this question. Wallner and Vaidya (2020) have responded by offering an axiomatic account of the explanatory power of essence. This paper discusses their account in light of some recent criticism by Bovey (2022). Building on work by Glazier (2017), Bovey succeeds in showing that Wallner (...) and Vaidya’s account is in need of modification and clarification. In this paper, I take up Bovey’s challenge and argue that Wallner and Vaidya have the resources available to incorporate the necessary modifications. I discuss the details of this modification, specifically, the question of what kind of metaphysical explanation is at work in the explanation of the necessity of essence itself. To get clear on this, I will introduce the distinction between generative and non-generative metaphysical explanation. In this way the paper contributes to both, the debate about whether essences can explain necessity and to the ongoing debate about metaphysical explanation. (shrink)

This book sets out a Kant-inspired theory of modality, driven by a methodology which takes seriously questions about the function of modal judgment as a guide to a metaphysics of modality. It argues that we need logical modal concepts as a condition on our ability to think, and metaphysical modal concepts as a condition on our ability to think objectively. Concordant with this, it argues that logical necessity has its source in the laws of thought and that (...) class='Hi'>metaphysical necessity is relative to conditions on objective thought. This this account of metaphysical necessity, which is termed “Modal Transcendentalism”, is then further developed, covering questions concerning necessary and contingent existence, de re necessity, essentialism, and modal epistemology.

In the past three decades there has been a rapid development of the formal machinery for modal logic. Quantified modal logic has developed along with a semantics and model theory that is appropriate to it. With this technical development there has been relatively little discussion of what modality is all about. There are two fundamental questions that have gone unanswered. First, to what does necessity amount? Is this a new logical notion, or is it something that can be further (...) analyzed in terms of other notions that we already have at our disposal? The second question is what makes truths involving necessity true? What is their ontological grounding in the world? This essay is directed at the first of these questions. ;There are three possible reductions of metaphysical modality. First, there is the reduction suggested by the semantics for modal logic: a reduction in terms of possible worlds. Second, there is the reduction in terms of cognition. What is possible is what is conceivable. Third, there is the reduction in terms of language. Necessities arise from the structures of language and/or language use. ;I argue that none of these is successful. All of them suffer either from presupposing some form of metaphysical necessity in the reductive base, rendering them circular and not truly reductive, or they do not do justice to the modality being reduced. ;Since necessity is not reducible to any non-modal features of the world, we need to determine whether we ought to reject it as unacceptable on this basis, or whether we ought to retain it, but treat is as a new primitive that is introduced into a philosophical or logical theory. I urge the latter course is the one that we ought to take because without it too many things will likewise be deemed unacceptable. Causal necessity and explanation, normally accepted theories or knowledge and perception, logic and logical validity, and one common manner of distinguishing sets from properties will be deemed unacceptable if de re necessity is unacceptable. All of these presuppose de re metaphysical necessity in some way. I conclude that de re metaphysical necessity ought to be retained in our theory as primitive, unanalyzable notion. (shrink)

The purpose of this thesis is to demonstrate that metaphysics is a necessary discipline -- necessary in the sense that all areas of philosophy, all areas of science, and in fact any type of rational activity at all would be impossible without a metaphysical background or metaphysical presuppositions. Because of the extremely strong nature of this claim, it is not possible to put forward a very simple argument, although I will attempt to construct one. A crucial issue here (...) is what metaphysics in fact is -- the nature of metaphysics. The conception of metaphysics which I support could be called Aristotelian, as opposed to Kantian: metaphysics is the first philosophy and the basis of all other philosophical and scientific inquiry. I will argue that this is indeed the most plausible conception of metaphysics. (shrink)
