This paper combines two ideas: (1) That the Lewisian best system analysis of lawhood (BSA) can cope with laws that have exceptions (cf. Braddon-Mitchell in Noûs 35(2):260–277, 2001; Schrenk in The metaphysics of ceteris paribus laws. Ontos, Frankfurt, 2007). (2) That a BSA can be executed not only on the mosaic of perfectly natural properties but also on any set of special science properties (cf., inter alia, Schrenk 2007, Selected papers contributed to the sections of GAP.6, 6th international (...) congress of the society for analytical philosophy. Mentis, Paderborn/Münster, 2008; Cohen and Callender in Philos Stud 145:1–34, 2009, Erkenntnis 73:427–447, 2010).

Metaphysics and science have a long but troubled relationship. In the twentieth century the Logical Positivists argued metaphysics was irrelevant and that philosophy should be guided by science. However, metaphysics and science attempt to answer many of the same, fundamental questions: What are laws of nature? What is causation? What are natural kinds? -/- In this book, Markus Schrenk examines and explains the central questions and problems in the metaphysics of science. He reviews the development of the field from (...) the early modern period through to the latest research, systematically assessing key topics including -/- dispositions, counterfactual conditionals, laws of nature, causation, natural kinds, essence, necessity. -/- With the addition of chapter summaries and annotated further reading, Metaphysics of Science is a much-needed, clear and informative survey of this exciting area of philosophical research. It is essential reading for students and scholars of philosophy of science and metaphysics. (shrink)

Since the mid-90s dispositionalism, the view that dispositions are irreducible, real properties, gained strength due to forceful counterexamples (finks and antidotes) that could be launched against Humean anti-dispositionalist attempts to reductively analyse dispositional predicates. -/- In the light of these anti-Humean successes, and in combination with ideas surrounding metaphysical necessity put forward by Kripke and Putnam, some dispositionalists felt encouraged to propose a strong anti-Humean view under the name of “Dispositional Essentialism”. -/- In this paper, I show that, ironically, the (...) counterexamples dispositionalists have used against the Humean reductive analysis of dispositional predicates also prove to be problems for a strong form of dispositional essentialism that assimilates dispositionality and metaphysical necessity. -/- Help comes from an unlike ally—Carnapian reductions sentences—but the alliance is not unproblematic.

Many philosophers of science think that most laws of nature (even those of fundamental physics) are so called ceteris paribus laws, i.e. roughly speaking, laws with exceptions. Yet, the ceteris paribus clause of these laws is problematic. Amongst the more infamous difficulties is the danger that ‘For all x: Fx then Gx, ceteris paribus’ may state no more than a tautology: ‘For all x: Fx then Gx, unless not’. One of the major attempts to avoid this problem (and others concerning (...) ceteris paribus laws) is to claim that the subject matter of laws are ascriptions of dispositions, powers, capacities etc., and not the regular behaviour we find in nature. That we do not know whether the cetera are paria in a specific situation does not matter to the dispositionalist because the objects have the disposition regardless of the circumstances. The defence of the latter claim is that dispositions can be instantiated without being manifested. Hence, the laws that ascribe dispositions are strict and it looks as if they do not face the above mentioned problems of ceteris paribus laws. In this chapter I attempt to show that these assumptions are wrong. I hope to illustrate that not only does the ceteris paribus clause reoccur inside the dispositions, moreover, there are laws – laws about non-fundamental entities with instable dispositions – which bear a ceteris paribus clause that cannot be hidden in a disposition.

The better best system account, short BBSA, is a variation on Lewis’s theory of laws. The difference to the latter is that the BBSA suggests that best system analyses can be executed for any fixed set of properties. This affords the possibility to launch system analyses separately for the set of biological properties yielding the set of biological laws, chemical properties yielding chemical laws, and so on for the other special sciences. As such, the BBSA remains silent about possible interrelations (...) between these freestanding sets of laws. In this paper, I explicate an emergence relation between them which preserves the autonomy or novelty of each special science’s laws but also shows their dependence: the autonomy of each level’s generalisations is given because nomicity is conferred to them system intrinsic, their dependence is established via their supervenience on lower level laws. As will be shown, the autonomy of special science laws is further strengthened by their ceteris paribus character. (shrink)

Since causal processes can be prevented and interfered with, law-governed causation is a challenge for necessitarian theories of laws of nature. To show that there is a problematic friction between necessity and interference, I focus on David Armstrong's theory; with one proviso, his lawmaker, nomological necessity, is supposed to be instantiated as the causation of the law's second relatum whenever its first relatum is instantiated. His proviso is supposed to handle interference cases, but fails to do so. In order to (...) be able to handle interferences, any theory which utilizes a kind of necessitation as lawmaker has to downgrade what it treats as necessity to something more akin to (Newtonian) forces.

This essay attempts to demonstrate that it is doubtful if Galileo's famous thought experiment concerning falling bodies in his 'Dialogues Concerning Two New Sciences' (Galileo 1954: 61-64) actually does succeed in proving that Aristotle was wrong in claiming that "bodies of different weight […] move […] with different speeds which stand to one another in the same ratio as their weights," (Galileo 1954: 61). (Part I); and further that it is likewise doubtful that that argument does or even can establish (...) Galileo's own famous 'Law of Falling Bodies,' viz., that regardless of their weight all bodies fall with the same speed. (Part II). (shrink)

Hume glaubte, die Kausalverknüpfung sei eine „secret connection“, also eine Verknüpfung, die mindestens unerkennbar, wenn nicht sogar inexis- tent ist. Einige moderne Gegner Humes halten dem entgegen, dass apos- teriorisch entdeckte, metaphysische Notwendigkeit, wie wir sie bei- spielsweise von Kripke und Putnam kennen, diejenige objektiv-reale Verknüpfung in der Welt ist, die auch die Rolle einer kausalen Verknüp- fung in der Welt spielen kann. Ich hinterfrage diese anti-Hume’sche Identifizierung kausaler mit me- taphysischer Notwendigkeit, zeige aber auch einen anderen Weg auf, kausale (...) Kräfte zu postulieren: Wenn unsere willentlichen Handlungen auf Widerstände in der Welt stoßen, haben wir (direkten) Beobachtungszu- gang zu einer Verknüpfung in der Welt, die mindestens einen essentiellen Teil kausaler Kraft ausmacht.

This paper concerns anti-Humean intuitions about connections in nature. It argues for the existence of a de re link that is not necessity.Some anti-Humeans tacitly assume that metaphysical necessity can be used for all sorts of anti-Humean desires. Metaphysical necessity is thought to stick together whatever would be loose and separate in a Hume world, as if it were a kind of universal superglue.I argue that this is not feasible. Metaphysical necessity might connect synchronically co-existent properties—kinds and their essential features, (...) for example—but it is difficult to see how it could also serve as the binding force for successions of events. That is, metaphysical necessity seems not to be fit for diachronic, causal affairs in which causal laws, causation, or dispositions are involved. A different anti-Humean connection in nature has to do that job.My arguments focus mainly on a debate which has been the battleground for Humean vs. anti-Humean intuitions for many decades—namely, the analysis of dispositional predicates—yet I believe (but do not argue here) that the arguments generalise to causation and causal laws straightforwardly.

In their recent book Every Thing Must Go, Ladyman and Ross claim: (i) Physics is analytically complete since it is the only science that cannot be left incomplete. (ii) There might not be an ontologically fundamental level. (iii) We should not admit anything into our ontology unless it has explanatory and predictive utility. In this discussion note I aim to show that the ontological commitment in implies that the completeness of no science can be achieved where no fundamental level exists. (...) Therefore, if claim requires a science to actually be complete in order to be considered as physics,, and if Ladyman and Ross's “tentative metaphysical hypothesis ... that there is no fundamental level” is true,, then there simply is no physics. Ladyman and Ross can, however, avoid this unwanted result if they merely require physics to ever strive for completeness rather than to already be complete. (shrink)

This is a book review of Barbara Vetter's Potentiality. -/- Philosophy is most intriguing when it teaches us seeing differently. Barbara Vetter’s book Po- tentiality & Possibility (OUP 2014) offers us precisely that: a new orthodoxy when it comes to our view of dispositions, possibility, and, most of all, potentiality. And it does so commendably well with the clarity of expression and the precision we often miss in the literature on causal powers and the like. -/- Vetter writes on page (...) 228: “This book is meant to be the beginning of a debate, not its end.” It is a pleasure and honour to be part of that beginning. Let us start. -/- A first big part of her book aims to show that the standard semantic and/or metaphysical inter- pretation of dispositional predicates and/or dispositions fails and that it ought to be replaced by her potentiality metaphysics. The first half of this commentary, 1., concerns consequences this view has. -/- A second huge part of Vetter’s project is to analyse possibility in terms of potentiality. This will be the focus of the second part, 2., of this review. (shrink)

I argue for the possibility of a proprioceptive art in addition to, for example, visual or auditory arts, where aspects of some martial arts will serve as examples of that art form. My argument is inspired by a thought of Ted Shawn’s, one of the pioneers of American modern dance: "Dance is the only art wherein we ourselves are the stuff in which it is made.” In a first step, I point out that in some practices of martial arts (in (...) the paper I will introduce “hyongs” & “katas”), we are, too, the stuff these performances are made of. Second, I show that we, as martial arts practitioners, are not in the first place visual or auditorial observers (as common in painting or music or ballet) but introspective, proprioceptive perceivers of our bodies and their movements. (As a corollary we get that we are, in such a case, necessarily our exclusive audience.) In an third crucial step, I show that the martial arts practices referred to, hyongs & katas, and especially the proprioceptive aspects thereof, can indeed count as art. Thus, proprioceptive art is possible because some practices of some martial arts are actual existing examples of that art form. (shrink)

This paper explores whether it is possible to reformulate or re-interpret Lewis’s theory of fundamental laws of nature—his “best system analysis”—in such a way that it becomes a useful theory for special science laws. One major step in this enterprise is to make plausible how law candidates within best system competitions can tolerate exceptions—this is crucial because we expect special science laws to be so called “ceteris paribus laws ”. I attempt to show how this is possible and also how (...) we can thereby make the first step towards a solution for the infamous difficulties surrounding the troublesome ceteris paribus clause. The paper outlines the general ideas of the theory but also points out some of its difficulties and background assumptions. (shrink)

Metaphysics of Science is the philosophical study of key concepts that figure prominently in science and that, prima facie, stand in need of clarification. It is also concerned with the phenomena that correspond to these concepts. Exemplary topics within Metaphysics of Science include laws of nature, causation, dispositions, natural kinds, possibility and necessity, explanation, reduction, emergence, grounding, and space and time. Metaphysics of Science is a subfield of both metaphysics and the philosophy of science—that is, it can be allocated to (...) either, but it exhausts neither. Unlike metaphysics simpliciter, Metaphysics of Science is not primarily concerned with metaphysical questions that may already arise from everyday phenomena such as what makes a thing (a chair, a desk) the very thing it is, what its identity criteria are, out of which parts is it composed, whether it remains the same if we exchange a couple of its parts, and so forth. Nor is it concerned with the concrete entities (superstrings, molecules, genes, and so forth) postulated by specific sciences; these issues are the subject matter of the special philosophies of science (for example, of physics, of chemistry, of biology). Metaphysics of Science is concerned with more abstract and general concepts that inform all of these sciences. Many of these concepts are interwoven with each other. For example, metaphysicians of science inquire whether dispositionality, lawhood, and causation can be accounted for in nonmodal terms; whether laws of nature presuppose the existence of natural kinds; and whether the properties of macrolevel objects supervene on dispositional or nondispositional properties. This article surveys the scope (section 1), historical origin (section 2), exemplary subject matters (section 4), and methodology (section 5) of Metaphysics of Science, as well as the motivation that drives it (section 3).

In his Contributions to the Analysis of the Sensations (Mach 1885) the phenomenalist philosopher Ernst Mach confronts us with a difficulty: “If we regard the Ego as a real unity, we become involved in the following dilemma: either we must set over against the Ego a world of unknowable entities […] or we must regard the whole world, the Egos of other people included, as comprised in our own Ego.” (Mach 1885: 21) In other words, if we start from a (...) phenomenalist viewpoint, i.e., if we believe that the manifold of sensations we are confronted with is ontologically fundamental —as Mach clearly does: “For us, colors, sounds, spaces, times,… are the ultimate ele-ments” (Mach 1885: 23)—then we are in danger to end up in solipsism. Unless, that is, we assume that some underlying thing-in-itself substratum from which matter, we ourselves, and all the others emanate. The only other alter-native seems to be—and Mach advertises it vehemently for he denies any “mons-trous notion of a thing-in-itself” (Mach 1885: 6)1—that we get rid of the Ego. For, if there is no Self in the first place, then the question whether there are others dissolves. To put it the other way round, it is ok that the others do not exist because, really, I do not exist either. If the Ego is a Myth solipsism is not just wrong but nonsense. There are two questions this paper wishes to address: first, do we need independent additional support for the denial of the Self or is the avoidance of solipsism reason enough to assume the Ego’s non-existence? I will argue that we do need additional reasons and I will evaluate those that Mach indeed gives to prove that “the primary fact is not the I, the Ego, but the elements (sensations)” (Mach 1885: 19). Second, is the deconstruction of the I, even if further sufficient support can be found, really adequate to stop us from worrying about solipsism? The doubt I will put forward is that the illusion of a Self might conjure up enough of an Ego—just like feeling a pain is having a pain, even if it is located in a phantom limb—to start us wondering whether it also occurs elsewhere.

The Philosophy ofLanguage belongs to the foundations of philosophical reflexion. In this volume, its central problems and strategies are explained, and the nature of sentences and other elements of language are analysed. The didactical exposition of the most important schools and thinkers makes the volume particularly interesting for readers new to the subject.

It is widely believed that at least two developments in the last third of the 20th century have given dispositionalism—the view that powers, capacities, potencies, etc. are irreducible real properties—new credibility: (i) the many counterexamples launched against reductive analyses of dispositional predicates in terms of counterfactual conditionals and (ii) a new anti-Humean faith in necessary connections in nature which, it is said, owes a lot to Kripke’s arguments surrounding metaphysical necessity. I aim to show in this paper that necessity is, (...) in fact, of little help for the dispositionalists. My argument makes use of one of the above mentioned counterexamples against Humean reduction: antidotes. Turning the tables, I ask how the dispositionalists themselves can deal with antidotes. The result will be to show that if the dispositionalists are to demystify antidote cases, they must make plausible a conceptualisation of dispositions that does not invoke any kind of necessity. I will cautiously suggest that the anti-Humean link dispositions bring to the world has to be thought of in terms of (Newtonian) forces. (shrink)

The verification theory of meaning aims to characterise what it is for a sentence to be meaningful and also what kind of abstract object the meaning of a sentence is. A brief outline is given by Rudolph Carnap, one of the theory's most prominent defenders: If we knew what it would be for a given sentence to be found true then we would know what its meaning is. [...] thus the meaning of a sentence is in a certain sense identical (...) with the way we determine its truth or falsehood; and a sentence has meaning only if such a determination is possible. [4: 420] In short, the verification theory of meaning claims that the meaning of a sentence is the method of its verification. (shrink)

It is a pleasure to welcome this long awaited set of translations, texts and commentaries. A renewed interest in Hellenistic philosophy has fostered a wealth of important scholarship, but the lack of an adequate sourcebook has seriously hampered scholars' ability to present this material to students and to make these thinkers more widely known in the philosophical community. The research of both Long and Sedley is much respected, and it is fortunate that such thorough scholars were chosen to make this (...) material available. Volume 1 is a collection of translations followed by philosophical notes. Volume 2 contains the texts, apparatus criticus, and supplementary notes of a more technical and philological nature, as well as an extensive bibliography. (shrink)

The striking difference between the orthodox nomological necessitation view of laws and the claims made recently by Scientific Essentialism is that on the latter interpretation laws are metaphysically necessary while they are contingent on the basis of the former. This shift is usually perceived as an upgrading: essentialism makes the laws as robust as possible. The aim of my paper—in which I contrast Brian Ellis’s Scientific Essentialism and David Armstrong’s theory of nomological necessity—is threefold. (1) I first underline the familiar (...) fact that metaphysical necessity (of Kripkean “water is necessarily H2O” kind) is not a stronger kind of necessity than nomological necessity but an entirely different kind of thing: nomological, but not metaphysical necessity, is an intra-world necessitation which Armstrong (almost) identifies with causation; metaphysical, but not nomological necessitation, has a canonical link to possible world considerations and counterfactual reasoning. Hence, the change from one necessity to the other is not an upgrading but a substantial shift. (2) I will explain how the essentialists, who promote this shift, are nonetheless able to retain the features of nomological necessity. (3) I also explore, for both the essentialist and the Armstrongian, whether they could extract a modal force from intra-world nomological necessity which it does not have per se. I argue that such a modal force is, indeed, obtainable for them. I will close the paper with some remarks and questions about the relation between Kripkean metaphysical necessity and the modal version of nomological necessity as defined in (3). (shrink)

This volume covers a great range of topics within general metaphysics, featuring contributions by experts in the respective areas. The information contained is suitable for introductory as well as research purposes. The book equally targets laymen, students, and experts in their own right. Subjects range from the history of metaphysics, properties, objects, modality, structure, truth, etc. to methodological concerns of metaphysics.

Although there is an ongoing controversy in philosophy of science about so called ceteris paribus laws that is, roughly, about laws with exceptionsóa fundamental question about those laws has been neglected (ß2). This is due to the fact that this question becomes apparent only if two different readings of ceteris paribus clauses in laws have been separated. The first reading of ceteris paribus clauses, which I will call the epistemic reading, covers applications of laws: predictions, for example, might go wrong (...) because we do not know all the relevant factors which are causally effective in relevant situation. The second reading, which I will call the metaphysical reading, is concerned with the laws themselves and their possible exceptions (ß3). It is this latter readingóand the funda- mental question associated with itówhich has been neglected due to the confusion of the two readings (ß4): if we leave epistemic issues aside is there at all conceptual space left for a notion of laws of nature which allows the laws themselves to have exceptions? I call a law with exceptions in this sense, if such there is, a real ceteris paribus law. To tackle this question, I distinguish grounded laws from non-grounded laws (ß5). A grounded law is, roughly, a law about structured entities where the properties of the parts of that structure figure themselves in laws of nature (ß6). I will claim that, since the substructure of such an entity can be damaged, grounded laws themselves can face exceptions. Hence, they are candidates to be real (metaphysical) ceteris paribus laws in the sense of my central question. I will discuss grounded laws and their exceptions in detail (ß7, ß8, ß9). For reasons of space, the further question whether we can even have a notion of fun- damental (non-grounded) laws that allows for exceptions cannot be discussed here. I will, however, give a positive answer and also outline how I have argued for that claim elsewhere (ß10). (shrink)

The articles in this special issue of the yearbook Logical Analysis and History of Philosophy all concern, in one way or another, Hume’s epistemology and metaphysics. There are discussions of our knowledge of causal powers, the extent to which conceivability is a guide to modality, and testimony; there are also discussions of our ideas of space and time, the role in Hume’s thought of the psychological mechanism of ‘completing the union’, the role of impressions, and Hume’s argument against the claim (...) that our perceptions are ‘locally conjoined’ with any entity (namely, a soul).

The notion of a law of nature is a central component of our scientific and philosophical conception of reality. The lawful character of our world makes natural phenomena predictable, understandable and manipulable in specific ways. This book provides a systematic overview of the most important philosophical conceptions of laws and concludes with a presentation of a novel version of the best systems theory.

This new study, an updated version of the author's doctoral dissertation, is a detailed investigation of Porphyry's one extant commentary on Aristotle's Categories and Plotinus' critique of Aristotle's doctrine of categories in "On the Kinds of Being". Evangeliou's investigation is limited by the fact that Porphyry's work was written for the student in an elementary "question and answer" format, yet Evangeliou is still able to decipher his general approach to Aristotle, which is respectful and conciliatory. In stark contrast is Plotinus' (...) work, which makes little attempt to interpret Aristotle in a generous manner and rejects most of his doctrine of categories. (shrink)
