Re-Engineering Philosophy for Limited Beings is about new approaches to many of the big topics in philosophy of science today, but with a very different take. To begin with, we are urged to reject the received Cartesian-Laplacean myths: Descartes’ certainty and Laplace’s computational omniscience. Instead, Wimsatt re-engineers a philosophy for human beings with all their cognitive limitations. His approaches find their starting point in the actual practices of scientists themselves, which he strongly identifies with engineering practices as the source of (...) researchers’ solutions for dealing with a complex world. He aims to construct an understanding of scientific methodology around the central role of reduction. But he dismisses eliminative reductionism in favor of a heuristic-based realist view. Wimsatt’s world is a complex one, and this means that science needs to do away with all the absolute and simple answers, because they do not reflect the world we are living in. A complex world requires the mindset and tinkering of an engineer to uncover its reality. The appropriate response must be heuristics all the way down as we constantly seek out reliable inferences on often shifting ground. To this end, we aim for models and theories that are robust, just as engineers aim to build robust machines. And although errors occur and approaches are fallible, they allow us to continually adapt the heuristics applied and sharpen our perceptions so as to develop more refined tools for investigating and understanding the world.

Name der Zeitschrift: Byzantinische Zeitschrift Jahrgang: 110 Heft: 3 Seiten: 749-754.

Die Frage nach dem Menschenbild wird immer dann laut, wenn Fundamentales zur Diskussion steht. In der heutigen Zeit sind dies vor allem Herausforderungen im Rahmen sozio-ökonomischer und technologischer Kontexte wie z.B. globale Finanzkrisen oder Visionen einer biomedizinischen "Verbesserung" des Menschen. Der vorliegende Band vermittelt einen Eindruck von der Vielgestaltigkeit der Versuche, die Frage nach dem Menschenbild, die lange Zeit in den Hintergrund der ethischen Diskussion getreten war, wieder aufzugreifen. (Verlags-Text).

Seit den 50er Jahren des 20. Jahrhunderts war umstritten, welches Gewicht Nietzsches Nachlass für sein Philosophieren und das Bild seiner Philosophie zukommt. Sagten die einen, hier vor allem Karl Schlechta, der Nietzsches Werke neu herausgab, es stehe nichts im Nachlass, was sich nicht auch im veröffentlichten Werk finde, so Karl Löwith und Martin Heidegger, „Was Nietzsche zeit seines Schaffens selbst veröffentlicht hat, ist immer Vordergrund. Die eigentliche Philosophie bleibt als,Nachlaߑ zurück" (Heidegger). Beides ist aus heutiger Sicht unhaltbar. Die neue manuskriptgetreue (...) Edition des Nachlasses in diplomatischer Transkription lässt die Frage nun methodisch entscheiden. Der international renommierte Nietzsche-Forscher Werner Stegmaier, der Jahrzehnte lang auch die Nietzsche-Studien und die Reihe Monographien und Texte zur Nietzscheforschung mitherausgegeben hat, legt dazu eine grundlegende Studie zur neuen textnahen oder kontextuellen, differentiellen und chronologischen Nietzsche-Interpretation vor. Diese lässt den Denker an der Arbeit, in seinem experimentellen philosophischen Orientierungsprozess beobachten. Daraus werden auch seine berühmten Lehren vom Übermenschen, vom Willen zur Macht, von der ewigen Wiederkunft und von den Herren der Erde in Also sprach Zarathustra neu verständlich. (shrink)

Der Band vereinigt 20 Studien zu Nietzsche von Werner Stegmaier, der in den vergangenen drei Jahrzehnten der internationalen Nietzsche-Forschung starke Impulse gegeben und zuletzt achtzehn Jahre lang, zusammen mit Günter Abel, die Nietzsche-Studien, das international führende Organ der Nietzsche-Forschung, geleitet und die Monographien und Texte zur Nietzsche-Forschung herausgegeben hat. Die Studien handeln von Grundfragen der Philosophie Nietzsches. Sie setzen ein (I) mit seiner Neubestimmung der Wahrheit und der Philosophie und (II) seiner Verzeitlichung des Denkens unter (III) Verzicht auf, die (...) Vernunft' bei der Bestimmung des Menschen, interpretieren von hier aus (IV) die Anti-Lehren von Nietzsches Zarathustra, umreissen (V) Nietzsches Ethik für, gute Europäer' und schliessen (VI) mit der Interpretation von Nietzsches Selbsteinschätzung als Schicksal der Philosophie und der Menschheit (Ecce homo, Warum ich ein Schicksal bin 1) und einer Einschätzung von Nietzsches Zukunft, die schon seit über einem Jahrhundert begonnen hat. Werner Stegmaier, Jahrgang 1946, war Gründungsdirektor des Instituts für Philosophie der Universität Greifswald nach dem Zusammenbruch der Sowjetunion und baute das Nord- und osteuropäische Forum für Philosophie auf, das Institute für Philosophie rund um die Ostsee neu miteinander ins Gespräch brachte und dort zu philosophischen Neuorientierungen beitrug. Er hat auf vielfältigen Gebieten gearbeitet, unter anderem zur Metaphysik und ihrem Grundbegriff der Substanz, zu grossen Philosophen von der Antike bis zur Gegenwart, zur philosophischen Aktualität der jüdischen Tradition, vor allem aber zur Philosophie Nietzsches. Dabei ging es ihm stets um Fragen der Ersten Philosophie, insbesondere die, was unsere Realität ausmacht, wie sie durch Zeichen und Kommunikation vermittelt wird, wie Begriffe in der Zeit existieren und womit man es beim Denken zu tun hat. Er führte den Begriff der Orientierung als elementaren Begriff der Philosophie ein und entwickelte eine umfassende Philosophie der Orientierung."--Publisher's website. (shrink)

Diese Festschrift umfasst 22 nationale und internationale Beiträge zu Ehren des Jubilars, darunter von solch renommierten Autoren wie Werner Flach, Christian Krijnen, Ulrich Blau, Erhard Oeser, Hans-Dieter Klein, um nur diese zu nennen. – Sie enthält ferner eine Stellungnahme von K. W. Zeidler, wo dieser im Dialog mit den Beiträgern jeweilige kritische Punkte seiner Schlusslogischen Letztbegründung klar zu stellen sich bemüht. – Ein Siglen- und Abkürzungsverzeichnis sowie eine Bibliographie des Jubilars runden die Ausgabe ab. Kurt Walter Zeidler darf als (...) einer jener selten gewordenen Denker gelten, die in unermüdlichem Reflexionseinsatz seit Jahrzehnten sich für die seit längerem in Gefahr geratene klassische Philosophie auf einem ihrer Hochplateaus, der Transzendentalphilosophie, genauer noch: deren postneukantianischer Erscheinungsform einsetzen, dies im lebendigen Wechselgespräch mit einer Reihe von Meisterdenkern von Platon und Aristoteles an über Leibniz, die neuzeitliche Aufklärung hin zu Kant, dann über Fichte, Hegel, Schelling zu ausgewählten Neukantianern sowie z. T. auch polemisch zu den ‚Modernen‘ und dem neo-nominalistischen Zeitgeist weithin. – Die Position Zeidlers dem allen gegenüber ist im Grunde sehr einfach zu kennzeichnen: Es ist ein Denken einer ihre eigene Geschichte in ihren ‚großen‘ Gestalten einbeziehenden Vernunft, die in ihrem Prinzipien-Selbst als theoretischer wie praktischer Erst- und Gesamtgrund menschliche Würde wie auch diesheitliche Ganzheit zu fundieren und zu garantieren vermag. – Zeidler darf in diesem Panorama mit Fug und Recht als eine Art Leuchtturm im rasch wechselnden Gewölk modernen und nachmodernen Gedankenlebens erscheinen.

Certain scientific explanations of physical facts have recently been characterized as distinctively mathematical –that is, as mathematical in a different way from ordinary explanations that employ mathematics. This article identifies what it is that makes some scientific explanations distinctively mathematical and how such explanations work. These explanations are non-causal, but this does not mean that they fail to cite the explanandum’s causes, that they abstract away from detailed causal histories, or that they cite no natural laws. Rather, in these explanations, (...) the facts doing the explaining are modally stronger than ordinary causal laws or are understood in the why question’s context to be constitutive of the physical arrangement at issue. A distinctively mathematical explanation works by showing the explanandum to be more necessary than ordinary causal laws could render it. Distinctively mathematical explanations thus supply a kind of understanding that causal explanations cannot. 1 Introduction2 Some Distinctively Mathematical Scientific Explanations3 Are Distinctively Mathematical Explanations Set Apart by their Failure to Cite Causes? 4 Distinctively Mathematical Explanations do not Exploit Causal Powers5 How these Distinctively Mathematical Explanations Work6 Conclusion.

It has often been argued that Humean accounts of natural law cannot account for the role played by laws in scientific explanations. Loewer (Philosophical Studies 2012) has offered a new reply to this argument on behalf of Humean accounts—a reply that distinguishes between grounding (which Loewer portrays as underwriting a kind of metaphysical explanation) and scientific explanation. I will argue that Loewer’s reply fails because it cannot accommodate the relation between metaphysical and scientific explanation. This relation also resolves a puzzle (...) about scientific explanation that Hempel and Oppenheim (Philosophy of Science 15:135–75, 1948) encountered. (shrink)

Humean accounts of natural lawhood have often been criticized as unable to account for the laws’ characteristic explanatory power in science. Loewer has replied that these criticisms fail to distinguish grounding explanations from scientific explanations. Lange has replied by arguing that grounding explanations and scientific explanations are linked by a transitivity principle, which can be used to argue that Humean accounts of natural law violate the prohibition on self-explanation. Lange’s argument has been sharply criticized by Hicks and van (...) Elswyk, Marshall, and Miller. This paper shows how Lange’s argument can withstand these criticisms once the transitivity principle and the prohibition on self-explanation are properly refined. The transitivity principle should be refined to accommodate contrasts in the explanans and explanandum. The prohibition on self-explanation should be refined so that it precludes a given fact p from helping to explain why some other fact q helps to explain why p. In this way, the transitivity principle avoids having counterintuitive consequences in cases involving macrostates having multiple possible microrealizations. The transitivity principle is perfectly compatible with the irreducibility of macroexplanations to microexplanations and with the diversity of the relations that can underwrite scientific explanations.

In the last five years there have been a number of results about the computable content of the prime, saturated, or homogeneous models of a complete decidable theory T in the spirit of Vaught's "Denumerable models of complete theories" combined with computability methods for degrees d ≤ 0′. First we recast older results by Goncharov, Peretyat'kin, and Millar in a more modern framework which we then apply. Then we survey recent results by Lange, "The degree spectra of homogeneous models," (...) which generalize the older results and which include positive results on when a certain homogeneous model of T has an isomorphic copy of a given Turing degree. We then survey Lange's "A characterization of the 0-basis homogeneous bounding degrees" for negative results about when does not have such copies, generalizing negative results by Goncharov, Peretyat'kin, and Millar. Finally, we explain recent results by Csima, Harizanov, Hirschfeldt, and Soare, "Bounding homogeneous models," about degrees d that are homogeneous bounding and explain their relation to the PA degrees.

Unlike explanation in science, explanation in mathematics has received relatively scant attention from philosophers. Whereas there are canonical examples of scientific explanations, there are few examples that have become widely accepted as exhibiting the distinction between mathematical proofs that explain why some mathematical theorem holds and proofs that merely prove that the theorem holds without revealing the reason why it holds. This essay offers some examples of proofs that mathematicians have considered explanatory, and it argues that these examples suggest a (...) particular account of explanation in mathematics. The essay compares its account to Steiner's and Kitcher's. Among the topics that arise are proofs that exploit symmetries, mathematical coincidences, brute-force proofs, simplicity in mathematics, merely clever proofs, and proofs that unify what other proofs treat as separate cases. (shrink)

Although all mathematical truths are necessary, mathematicians take certain combinations of mathematical truths to be ‘coincidental’, ‘accidental’, or ‘fortuitous’. The notion of a ‘ mathematical coincidence’ has so far failed to receive sufficient attention from philosophers. I argue that a mathematical coincidence is not merely an unforeseen or surprising mathematical result, and that being a misleading combination of mathematical facts is neither necessary nor sufficient for qualifying as a mathematical coincidence. I argue that although the components of a mathematical coincidence (...) may possess a common explainer, they have no common explanation ; that two mathematical facts have a unified explanation makes their truth non-coincidental. I suggest that any motivation we may have for thinking that there are mathematical coincidences should also motivate us to think that there are mathematical explanations, since the notion of a mathematical coincidence can be understood only in terms of the notion of a mathematical explanation. I also argue that the notion of a mathematical coincidence plays an important role in scientific explanation. When two phenomenological laws of nature are similar, despite concerning physically distinct processes, it may be that any correct scientific explanation of their similarity proceeds by revealing their similarity to be no mathematical coincidence. (shrink)

Many philosophers have believed that the laws of nature differ from the accidental truths in their invariance under counterfactual perturbations. Roughly speaking, the laws would still have held had q been the case, for any q that is consistent with the laws. (Trivially, no accident would still have held under every such counterfactual supposition.) The main problem with this slogan (even if it is true) is that it uses the laws themselves to delimit qs range. I present a means of (...) distinguishing the laws (and their logical consequences) from the accidents, in terms of their range of invariance under counterfactual antecedents, that does not appeal to physical modalities (or any cognate notion) in delimiting the relevant range of counterfactual perturbations. I then argue that this approach explicates the sense in which the laws possess a kind of necessity. (shrink)

Scientific essentialism aims to account for the natural laws' special capacity to support counterfactuals. I argue that scientific essentialism can do so only by resorting to devices that are just as ad hoc as those that essentialists accuse Humean regularity theories of employing. I conclude by offering an account of the laws' distinctive relation to counterfactuals that portrays laws as contingent but nevertheless distinct from accidents by virtue of possessing a genuine variety of necessity.

Several foundational documents of bioethics mention the special obligation researchers have to vulnerable research participants. However, the treatment of vulnerability offered by these documents often relies on enumeration of vulnerable groups rather than an analysis of the features that make such groups vulnerable. Recent attempts in the scholarly literature to lend philosophical weight to the concept of vulnerability are offered by Luna and Hurst. Luna suggests that vulnerability is irreducibly contextual and that Institutional Review Boards (Research Ethics Committees) can only (...) identify vulnerable participants by carefully examining the details of the proposed research. Hurst, in contrast, defines the vulnerable as those especially at risk of incurring the wrongs to which all research ethics participants are exposed. We offer a more substantive conception of vulnerability than Luna but one that gives rise to a different rubric of responsibilities from Hurst's. While we understand vulnerability to be an ontological condition of human existence, in the context of research ethics, we take the vulnerable to be research subjects who are especially prone to harm or exploitation. Our analysis rests on developing a typology of sources of vulnerability and showing how distinct sources generate distinct obligations on the part of the researcher. Our account emphasizes that the researcher's first obligation is not to make the research participant even more vulnerable than they already are. To illustrate our framework, we consider two cases: that of a vulnerable population involved in international research and that of a domestic population of people with diminished capacity. (shrink)

I identify the special sort of stability (invariance, resilience, etc.) that distinguishes laws from accidental truths. Although an accident can have a certain invariance under counterfactual suppositions, there is no continuum between laws and accidents here; a law's invariance is different in kind, not in degree, from an accident's. (In particular, a law's range of invariance is not "broader"--at least in the most straightforward sense.) The stability distinctive of the laws is used to explicate what it would mean for there (...) to be multiple grades (or degrees) of physical necessity. Whether there are is for science to discover. (shrink)

Really statistical explanation is a hitherto neglected form of noncausal scientific explanation. Explanations in population biology that appeal to drift are RS explanations. An RS explanation supplies a kind of understanding that a causal explanation of the same result cannot supply. Roughly speaking, an RS explanation shows the result to be mere statistical fallout.

Rosenberg has recently argued that explanations supplied by (what he calls) functional biology are mere promissory notes for macromolecular adaptive explanations. Rosenberg's arguments currently constitute one of the most substantial challenges to the autonomy, irreducibility, and indispensability of the explanations supplied by functional biology. My responses to Rosenberg's arguments will generate a novel account of the autonomy of functional biology. This account will turn on the relations between counterfactuals, scientific explanations, and natural laws. Crucially, in their treatment of the laws' (...) relation to counterfactuals, Rosenberg's arguments beg the question against the autonomy of functional biology. This relation is considerably more subtle than is suggested by familiar slogans such as Laws support counterfactuals; accidents don't. (shrink)

Recently, biologists and computer scientists who advocate the "strong thesis of artificial life" have argued that the distinction between life and nonlife is important and that certain computer software entities could be alive in the same sense as biological entities. These arguments have been challenged by Sober (1991). I address some of the questions about the rational reconstruction of biology that are suggested by these arguments: What is the relation between life and the "signs of life"? What work (if any) (...) might the concept of "life" (over and above the "signs of life") perform in biology? What turns on scientific disputes over the utility of this concept? To defend my answers to these questions, I compare "life" to certain other concepts used in science, and I examine historical episodes in which an entity's vitality was invoked to explain certain phenomena. I try to understand how these explanations could be illuminating even though they are not accompanied by any reductive definition of "life.". (shrink)

A conservation law in physics can be either a constraint on the kinds of interaction there could be or a coincidence of the kinds of interactions there actually are. This is an important, unjustly neglected distinction. Only if a conservation law constrains the possible kinds of interaction can a derivation from it constitute a scientific explanation despite failing to describe the causal/mechanical details behind the result derived. This conception of the relation between “bottom-up” scientific explanations and one kind of “top-down” (...) scientific explanation is motivated by several examples from classical and modern physics.

This paper argues that in at least some cases, one proof of a given theorem is deeper than another by virtue of supplying a deeper explanation of the theorem — that is, a deeper account of why the theorem holds. There are cases of scientific depth that also involve a common abstract structure explaining a similarity between two otherwise unrelated phenomena, making their similarity no coincidence and purchasing depth by answering why questions that separate, dissimilar explanations of the two phenomena (...) cannot correctly answer. The connections between explanation, depth, unification, power, and coincidence in mathematics and science are compared. (shrink)

Why should science be so interested in discovering whether p is a law over and above whether p is true? The answer may involve the laws' relation to counterfactuals: p is a law iff p would still have obtained under any counterfactual supposition that is consistent with the laws. But unless we already understand why science is especially concerned with the laws, we cannot explain why science is especially interested in what would have happened under those counterfactual suppositions consistent with (...) the laws. It is argued that the laws form the only non-trivially "stable" set, where "stability" is invariance under a certain range of counterfactual suppositions not itself defined by reference to the laws. It is then explained why science should be so interested in identifying a non-trivially "stable" set: because of stability's relation to the best set of "inductive strategies". (shrink)

After reviewing several failed arguments that laws cannot change, I use the laws' special relation to counterfactuals to show how temporary laws would have to differ from eternal but time-dependent laws. Then I argue that temporary laws are impossible and that neither Lewis's nor Armstrong's analyses of law nicely accounts for the laws' immutability. *Received September 2006; revised September 2007. ‡Many thanks to John Roberts and John Carroll for valuable comments on earlier drafts, as well as to several anonymous referees (...) for their good suggestions. †To contact the author, please write to: Department of Philosophy, University of North Carolina, CB #3125, Caldwell Hall, Chapel Hill, NC 27599-3125;.

Sober 2011 argues that, contrary to Hume, some causal statements can be known a priori to be true—notably, some ‘would promote’ statements figuring in causal models of natural selection. We find Sober's argument unconvincing. We regard the Humean thesis as denying that causal explanations contain any a priori knowable statements specifying certain features of events to be causally relevant. We argue that not every ‘would promote’ statement is genuinely causal, and we suggest that Sober has not shown that his examples (...) of ‘would promote’ statements manage to achieve a priori status without sacrificing their causal character.

Summary In this paper I inquire by way of a phenomenological description whether the experience of an encounter with one's own mortality could not so transform a person's ethos that the virtues of justice, compassion and neighborly love could ensue. I will concentrate on such an encounter in and through the mood of dread. This paper, in opposition to Heidegger, is only concerned with it's effect regarding our ethical comportment. I claim that the mood of dread not only destroys the (...) mood of indifference, but also sends him on a pathway of self‐transforming moods. As to the “understanding” accompanying moods in the field of ethical comportment I try to show that it has the character of a direct non‐ratiocinative insight.RésuméJe voudrais dans cet article examiner, à l'aide d'une description phénoménologique, si l'expérience que constitue la rencontre avec la perspective de sa propre mort ne peut pas transformer l'éthique d'un homme de telle manière que les vertus de justice, de pitié et de reconnaissance de la dignité humaine puissent s'y développer. Je me limite ici à une telle rencontre avec un sentiment d'horreur. Cet article n'aborde — contrairement à la manière dont Heidegger conçoit l'angoisse — que l'effet sur le comportement éthique. Je suis d'avis que le sentiment d'horreur non seulement détruit celui d'indifférence, mais dispose l'homme à vouloir se changer lui‐me̊me. Quant à la »compréhension« des sentiments accompagnant le comportement éthique, je montre qu'elle a le caractère d'une intuition immédiate et non rationnelle.ZusammenfassungIn diesem Aufsatz möchte ich auf dem Wege einer phänomenologischen Beschreibung untersuchen, ob die Erfahrung einer Begegnung mit der eigenen Sterblichkeit das Ethos eines Menschen nicht so verwandeln kann, dass sich die Tugenden von Gerechtigkeit, Mitleid und mitmenschlicher Anerkennung entwickeln können. Ich beschränke mich dabei auf eine solche Begegnung in der und durch die Gestimmtheit des Entsetzens. Dieser Aufsatz erörtert — im Gegensatz zu Heideggers Auffassung der Angst — nur die Wirkung auf unser ethisches Verhalten. Ich bin der Auffassung, dass die Gestimmtheit des Entsetzens nicht nur die Stimmung der Gleichgültigkeit zerstört, sondern den Menschen auch auf einen Weg der selbstverändernden Gestimmtheiten sendet. Was das »Verstehen« begleitender Stimmungen im Bereich des ethischen Verhaltens betrifft, so versuche ich zu zeigen, dass dies den Charakter eines unmittelbaren, nicht‐rationalen Einsehens hat.

Worldwide there are substantial differences within and between countries in aggression and violence. Although there are various exceptions, a general rule is that aggression and violence increase as one moves closer to the equator, which suggests the important role of climate differences. While this pattern is robust, theoretical explanations for these large differences in aggression and violence within countries and around the world are lacking. Most extant explanations focus on the influence of average temperature as a factor that triggers aggression, (...) or the notion that warm temperature allows for more social interaction situations in which aggression is likely to unfold. We propose a new model, CLimate, Aggression, and Self-control in Humans, that helps us to understand differences within and between countries in aggression and violence in terms of differences in climate. Lower temperatures, and especially larger degrees of seasonal variation in climate, call for individuals and groups to adopt a slower life history strategy, a greater focus on the future, and a stronger focus on self-control. The CLASH model further outlines that slow life strategy, future orientation, and strong self-control are important determinants of inhibiting aggression and violence. We also discuss how CLASH differs from other recently developed models that emphasize climate differences for understanding conflict. We conclude by discussing the theoretical and societal importance of climate in shaping individual and societal differences in aggression and violence. (shrink)

Suppose that unobtanium-346 is a rare radioactive isotope. Consider: (1) Every Un346 atom, at its creation, decays within 7 microseconds (µs). (50%) Every Un346 atom, at its creation, has a 50% chance of decaying within 7µs. (1) and (50%) can be true together, but (1) and (50%) cannot together be laws of nature. Indeed, (50%)'s mere (non-vacuous) truth logically precludes (1)'s lawhood. A satisfactory analysis of chance and lawhood should nicely account for this relation. I shall argue first that David (...) Lewis's Humean picture accounts for this relation only by inserting this relation ‘by hand’. Next, I shall argue that this relation between law and chance also threatens a radically non-Humean picture of laws and chances. Finally, I shall offer an account of natural law that nicely explains the relation between chancy facts and deterministic laws. This explanation is not ad hoc because it derives the relation from the very same features of lawhood that account for the laws' special relation to counterfactuals and explain how the laws (unlike the accidents) possess a variety of necessity. The reason that a chancy fact such as (50%) keeps (1) from being a law, without keeping (1) from being true, is ultimately that a chancy fact constrains the subjunctive facts and (1)'s lawhood, unlike (1)'s truth, depends upon the subjunctive facts.

The merits of David Lewis’s Best System Account of natural law are frequently debated. But to my knowledge, the prospects for extending the BSA to cover meta-laws have never been examined. I shall identify two obstacles facing the most natural way of extending the BSA to cover meta-laws. The BSA’s fans should consider how these obstacles are to be overcome. Meta-laws are laws about laws. For example, Einstein’s special theory of relativity incorporates a meta-law: The content of the [special] relativity (...) theory can … be summarized in one sentence: all natural laws must be so conditioned that they are covariant with respect to Lorentz transformations. [The special theory of relativity] is not a theory in the usual sense but is better regarded as a second-level theory, or a theory of theories that constrains first-level theories. The principle of relativity is an example of a symmetry principle: a principle requiring that the first-order laws be unchanged under a given transformation. Long before Einstein proposed the principle of relativity, other spacetime symmetries were widely believed to be meta-laws: that the first-order laws are covariant under arbitrary spatial displacements, temporal displacements and spatial rotations. These spacetime symmetries require the laws to treat all spatial locations and directions alike and all moments alike. For instance, symmetry under temporal displacements rules out a fundamental force law specifying that a given force declines with the inverse-square of the distance before a given moment but with the inverse-cube of the distance at and after that moment. Wigner characterizes such a symmetry principle as ‘a superprinciple which is in …. (shrink)

I am grateful to James Cordeiro, Timothy Murphy, Heloise Robinson and Teresa Baron for their perceptive and stimulating comments on my article in this journal. In what follows, I seek to respond to some of the main points raised in each commentary.
