I build a case for the impossibility of natural necessity as anything other than a species of metaphysical necessity – the necessity obtaining in virtue of the essences of natural objects. Aristotelian necessitarianism about the laws of nature is clarified and defended. I contrast it with E.J. Lowe’s contingentism about the laws. I examine Lowe’s solution to the circularity/triviality problem besetting natural necessity understood as relative necessity. Lowe’s way out is subject to (...) serious problems unless it is given an essentialist turn, which he declines to do. Further, his defence of contingency in terms of possible variation in the natural constants is found wanting, as is a related defence given by Kit Fine. I examine and raise problems for a recent, Lowe-inspired defence of a hybrid view of the modal status of laws given by Tuomas Tahko. Aristotelian necessitarianism, by contrast, can account for the sorts of phenomena to which contingentists typically appeal. (shrink)

The paper considers recent proposals by Armstrong, Dretske, and Tooley that revive the view that statements of laws of nature are grounded by the existence of higher order facts relating universals. Several objections to such a view are raised and an alternative analysis, recognizing general facts, is considered. Such an alternative is shown to meet a number of the objections raised against the appeal to higher order facts and it is also related to views of Hume and Wittgenstein. Further objections (...) are then raised to all the non-Humean "realist" attempts to provide special facts to ground the laws of nature. (shrink)

Are the relations between the property of a thing and its related disposition to react in certain ways, and between the triggering of that disposition and the consequent effect, necessary? Harré and Madden, in their analysis of causal powers, said they are, but their arguments are not persuasive. Humeans like Simon Blackburn deny it. I criticize the Humean position, and argue afresh for their necessity. I note that David Lewis' analysis of causation requires their necessity, though as a (...) confessed Humean he has not admitted this. (shrink)

Non‐Humean theories of natural necessity invoke modally‐laden primitives to explain why nature exhibits lawlike regularities. However, they vary in the primitives they posit and in their subsequent accounts of laws of nature and related phenomena (including natural properties, natural kinds, causation, counterfactuals, and the like). This article provides a taxonomy of non‐Humean theories, discusses influential arguments for and against them, and describes some ways in which differences in goals and methods can motivate different versions of non‐Humeanism (...) (and, for that matter, Humeanism). In short, this article provides an introduction to non‐Humeanism concerning the metaphysics of laws of nature and natural necessity. (shrink)

Some philosophers who believe that there are necessary connections in nature take it that an advantage of their commitment is that the problem of induction is solved. This paper aims to offer a comprehensive refutation of the arguments necessitarians use to show that if natural necessities are posited, then there is no problem of induction. In section 2, two models of natural necessity are presented. The “Contingent Natural Necessity” section examines David Armstrong’s explanationist ‘solution’ to (...) the problem of induction. The “Natural Necessity and IBE” section looks in detail into the claim that natural necessity is the best explanation of observed regularity. The “Dispositional Essentialism to the Rescue?” section moves on to Brian Ellis’s dispositional essentialist ‘solution’. The “Sankey’s Helping Hand” section examines Howard Sankey’s attempt to blend dispositional essentialism and explanationism. (shrink)

Nicholas Everitt's objection to my discussion of the regularity theory of causation is a common one. Ithink it misses the point, but the point it misses is in a way a delicate one, and hard to express, and the general worry he expresses is a natural one. For that reason it is important, and its importance is reflected in the fact that it is very difficult to find a satisfyingly substantive way of stating the difference between regularity theories of (...) causation and non-regularity theories of causation. I have had no new ideas about how to do this [...], but I will restate some of [my older] ideas [...], in order to try to answer Everitt [...]. (shrink)

Drawing the complex terrain of the theories of induction and of the various ways to ground inductive knowledge in the middle ages is the aim of this paper. There have already been two excellent attempts to draw this terrain. The first is by Julius R. Weinberg and the second by E. P. Bos. My attempt differs from theirs in two major respects. The first is that it is more detailed in the examination of the various theories and their relations. The (...) second is that I focus on the role of natural necessities in induction. In particular, I try to place the various conceptions of induction within a network of issues that relate to the problem of universals, natural necessities and a power-based approach to activity in nature. Here is the road map. Section 2 explains Aristotle’s views of induction, as this were mainly developed in Posterior Analytics Book II.19 and states what I take it to be the main dilemma of induction, as this was described by Sextus Empiricus: induction is either perfect and impossible or imperfect and unjustified. In section 3, I move to Thomas Aquinas and his own attempt to justify induction and the actuality of general and necessary principles based on experience by an appeal to the natural light of reason. In section 4 I discuss John Duns Scotus’s reliance on a self-evident maxim to bridge the gap between imperfect and perfect induction. Section 5 moves to William of Ockham ’s peculiar attempt to justify single-instance inductions. Then, section 6 offers a detailed account of Jean Buridan’s ground-breaking re-conceptualisation of induction and the role of intellect in it. Section 7 discusses the critique of induction by Nicolaus of Autrecourt. Finally, section 8 offers a brief account of Pseudo-Scotus’s move from knowledge to opinion. (shrink)

I want to examine a possible solution to the problem of induction-one which, as far as I know, has not been discussed elsewhere. The solution makes crucial use of the notion of objective natural necessity. For the purposes of this discussion, I shall assume that this notion is coherent. I am aware that this assumption is controversial, but I do not have space to examine the issue here.

When the atomic theory was revived in the seventeenth century, the atomists faced a problem concerning the status of the laws of nature. On the face of it, the postulation of absolutely hard, rigid, and impenetrable atoms seems to entail the existence of natural necessities and impossibilities: Atoms A and B cannot interpenetrate, so atom A must push atom B when they collide. The properties of compound bodies are to be explained in terms of their “textures” (i.e., the arrangements (...) of their constituent atoms) on the famous lock-and-key model. Once again, it looks as if we have a domain of natural necessities depending on the textures of compound bodies. But the atomists seem to think of the laws of nature as radically contingent, not the sorts of things that could in principle be known a priori. This article seeks to address this tension between what the atomists seem committed to by their matter theory (real necessary connections in nature) and what they in fact say (that all the laws are contingent). In my Atomism (1995) I sought to resolve the tension by appealing to a sharp distinction between the atomists’ metaphysics and their epistemology. On this interpretation, they remain committed to natural necessity, but insist that we can never do Natural Philosophy in the “high priori” manner, by discovering real essences and their necessary connections. Our sciences of nature must remain empirical. Since publication of Atomism, however, this possible solution of the problem has come to seem more doubtful. Reflection on the work of my three “dissenting voices” (Margaret Osler, Peter Anstey and Rae Langton) has forced a radical rethink, focussing on the problematic relation between the intrinsic properties of the atoms and their (dynamic) powers. If there is no discoverable intelligible connection between what the atom is in itself (its intrinsic properties) and what it does (its powers), then my earlier solution will turn out to be untenable.

Modal properties are notorious epistemic trouble-makers. That theme is very much at the heart of Michael Rea’s thesis that the Discovery Problem (roughly, the problem of explaining how we know when ascriptions of modal properties are true) has no naturalistic resolution. That might encourage the thought that supernaturalism will somehow resolve the problem. This paper argues that supernaturalism is unlikely to offer a solution of the Discovery Problem.

J. Ladyman, Ladyman and Ross refine J. Worral's structural realism, by developing an ontic structural realism which they argue is a consistently naturalistic means of characterizing the ontology of fundamental physics. I argue that particular elements of M. Lange and M. Eklund strengthen and refine their project of characterizing fundamental physics via OSR and by extension, their presentation of information-theoretic structural realism. I demonstrate this point by situating M. Lange’s discussion of nomological modality and natural necessity within Ladyman (...) and Ross’s discussion of ITSR. The logical hierarchy evinced in Lange’s notion of ‘nomic stability’ further refines Ladyman and Ross’s claims through the addition of nuanced modal distinctions in a systematic framework. Moreover, I argue that what Lange considers are the ‘lawmakers’ serve as a de dicto rendition of some of Ladyman & Ross’s fundamental de re extensions and refinements of ‘real patterns’. (shrink)

This provocative but persuasive book is essentially a radical attack upon the Humean conception of causality and the presentation and defense of a counter-theory, closer to everyday experience and pre-Humean traditional views. As formulated by empiricist philosophers, the Humean approach depends on two basic postulates. The philosophical analysis of any non-empirical concept must be a formal explication; any residue elements have to be accounted for in terms of their psychological origins. The world as experienced can be conceived adequately as a (...) logically independent system of things or flux of events, without the unwarranted assumption that individuals persist diachronically. As the grounds for undermining these assumptions, the authors develop a conception of causes as "powerful particulars," i.e., things which have both a nature and powers. So long as the nature remains unchanged the agent in question will continue to behave in this fashion with a natural necessity, stemming from the individual’s nature and specific powers. The opening chapter discusses the problem of conceptual and natural necessity—as distinct from logical necessity which alone is allowed by the Humean empiricists. Natural necessity is the mark of the relationship between real causes and their respective effects, whereas conceptual necessity characterizes the way our statements about such are themselves related. Later the irreducibility of natural necessity is emphasized and its differences from logical entailment spelled out. Chapter two takes up the subject of the "regularity theory and its allies." Characteristic of such are two claims: the empirical content of a causal-relationship statement is exhausted by the actual or hypothetical regularity between independent entities, and the necessity ordinarily attributed to causal production is an illusion, to be accounted for in various ways. Subsequent chapters are devoted to assaulting the pillars of the Humean notion either directly or indirectly through an illuminating and attractive account of their own theory of nature, causal powers, and natural necessity. The final chapter, entitled "Fields of Potential," indulges in speculation about the nature of ultimate entities on the basis of an extended generalization of the notion of the powerful individual, and concludes with a brief account of the historical antecedents of Faraday’s modern field theory and the metaphysical implications of a generalized field theory.—A.B.W.

In a previous issue of this journal, Professor R. A. Oakes compared Blanshard’s version of the entailment view of causality with Professor E. H. Madden’s version of the natural necessity view of causality [5]. Professor Oakes, after considering their alleged differences, asserted that these two views were the same. In the same issue, Professor Madden replied to Oakes’ remarks with a list of characteristics which allegedly distinguished his natural necessity view from the entailment view [3]. In (...) what follows I propose that Madden’s list of differentiating characteristics contains no essential, irreconcilable element which separates his view from Blanshard’s. Additionally, I will consider several features of the Madden and Blanshard views not considered by either Madden or Oakes in their articles which do in fact irreconcilably distinguish them. (shrink)

In this paper, I critically examine Harre and Madden's attempt, largely as it occurs in their Causal Powers, to secure for causes and laws of nature a kind of necessity which although consistent with commonsensical empiricism and anti-idealistic philosophy of science nevertheless runs counter to the humean-positivistic tradition, which denies the existence of any distinctively "natural" or causal necessity. In the course of the paper, I reveal the multifarious nature of their account and show that each part (...) of that account, commonsensical or ontological, is inadequate. I indicate as well how the multifarious nature of the account allows and even encourages an evasive shifting about in the face of adversity, which shifting no doubt contributes to whatever illusion of adequacy is present in their treatment.

There is a tension in scholarship about Aristotle’s philosophy, especially his philosophy of science, between empiricist readings and rationalist readings. A prime site of conflict is Posterior Analytics II.19 where Aristotle, after having said that we know the first principles by induction suddenly says that we know them by nous. Those taking the rationalist side find in nous something like a faculty of “intuition” and are led to the conclusion that by “induction” Aristotle has some kind of idea of “intuitive (...) induction”. Those taking the empiricist side resist this temptation but then struggle to explain how we can know first principles by induction and usually end by relegating induction to a mere subsidiary role; well-known problems of induction, with which Aristotle shows some familiarity, militate against taking anything we learn from induction to be a first principle or even certain. I am on the side of the empiricists, and would like to adopt as a methodological assumption that no concept of intuition occurs in any of Aristotle’s works. That is a far more ambitious project than I am attempting here, however. Here, I want to defend a non-intuitive, enumerative kind of induction against a raft of criticisms raised against it in the collection Shifting the Paradigm: Alternative Approaches to Induction. I want to defend the position that Hume and Aristotle have basically the same conception of induction and of what it can and cannot do. What it cannot do, for both, is prove natural necessities. A paradigm shift is neither necessary nor desirable for a proper understanding of Aristotle’s philosophy of science. Aristotle is still the empiricist philosopher we all thought he was before reading Posterior Analytics II.19. (shrink)

The focus of my dissertation is a general and comprehensive examination of Locke’s view of divine power. My basic argument is that John Locke is a theological voluntarist in his understanding of God’s creative and providential relationship with the world, including both the natural and moral order. As a voluntarist, Locke holds that God freely imposes both the physical and moral laws of nature onto creation by means of his will: this contrasts with the intellectualist perspective in which the (...) laws of nature emerge from the essences of things. For Locke, there are no intrinsically necessary laws in the created order: both physical and moral laws are arbitrary determinations of the divine will. While these laws are not intrinsically necessary, they are hypothetically necessary. Hypothetical necessity involves things that could have been otherwise, but which are necessary based on the supposition of a free action and other relevant conditions pertaining to the actor. Concerning God, we can understand hypothetical necessity in the following way: □ [ → Y]. X is a variable that ranges over a subset of contingent propositions about actions. ‘P’ is the proposition ‘God is perfect’. And Y is any proposition that is a necessary consequent of both X and P. In any possible world in which God performs X, it is the case that Y will obtain. Supposing that God decides to create beings like us, God must of necessity craft the moral laws of nature in a way that harmonizes with our nature. What grounds this necessity is that God must act consistently with the perfection of the divine nature: to give us a different law would be less than perfect. Furthermore, I argue that certain physical laws of nature – those that help to realize our nature – are also hypothetically necessary. (shrink)

This book, one of the first full-length studies of the modalities to emerge from the debate to which Saul Kripke, David Lewis, Ruth Marcus, and others are contributing, is an exploration and defense of the notion of modality de re, the idea that objects have both essential and accidental properties. Plantinga develops his argument by means of the notion of possible worlds and ranges over such key problems as the nature of essence, transworld identity, negative existential propositions, and the existence (...) of unactual objects in other possible worlds. He also applies his logical theories to the elucidation of two problems in the philosophy of religion: the problem of evil and the ontological argument. (shrink)
