A volume of papers inspired by the work of George E. Smith on confirmation and evidence in advanced science—from Newton's gravitation theory to the physics of molecules.

Logic isn’t special. Its theories are continuous with science; its method continuous with scientific method. Logic isn’t a priori, nor are its truths analytic truths. Logical theories are revisable, and if they are revised, they are revised on the same grounds as scientific theories. These are the tenets of anti-exceptionalism about logic. The position is most famously defended by Quine, but has more recent advocates in Maddy, Priest, Russell, and Williamson. Although these authors agree on many methodological issues about logic, (...) they disagree about which logic anti-exceptionalism supports. Williamson uses an anti-exceptionalist argument to defend classical logic, while Priest claims that his anti-exceptionalism supports nonclassical logic. This paper argues that the disagreement is due to a difference in how the parties understand logical theories. Once we reject Williamson’s deflationary account of logical theories, the argument for classical logic is undercut. Instead an alternative account of logical theories is offered, on which logical pluralism is a plausible supplement to anti-exceptionalism. (shrink)

In this chapter, we ask three questions about pedophilia: Is it immoral to be a pedophile? Is it immoral for pedophiles to seek out sexual contact with children? Is it immoral for pedophiles to satisfy their sexual preferences by using computer-generated graphics, sex dolls, and/or sex robots that mimic children? We argue that it is not immoral to be a pedophile, it is immoral for pedophiles to seek out sexual contact with children because of the expected harm to children, and (...) it is morally permissible for pedophiles to satisfy their sexual preferences in ways that do not involve any real children.

Introduction to this special issue of The Australasian Journal of Logic.

The paper presents a revised view of quantum mechanics centered on the notion (“genuine fortuitousness”) that the click in a counter is a totally lawless event, which comes by itself. A crucial point is the distinction between events on the spacetime scene and the content of the symbolic algorism. A revised conception of matrix variables emerges, by which such a variable, as part of a whole, does not have a value, under any circumstance. This conception is at variance with that (...) of indeterminate variables. A matrix variable not having a value does not enter spacetime and is not a measurable quantity, but manifests itself by a click in a counter with the remarkable property of having an onset, a beginning, from which the click develops. The individual click with its immense complexity is unique and lawless, even beyond probability. The notion of probability only applies to clicks in low resolution, and the completeness of a probabilistic theory is thereby seen in a new perspective. The genuinely fortuitous click is not produced by the impact of a particle, nor caused by an event in the source prior to the click in the counter. Indeed, there are no particles on the spacetime scene. The theory is thereby liberated from notions, which go with particles having indeterminate variables, and which have given to quantum mechanics the image of an unfathomable theory. With no particle as intermediary, the connection between source and detector is non-local, as is the entire theory, which deals exclusively with distributions of clicks. The locality permeating quantum mechanics is a symbolic one. The wave function enters in the sole role of encoding the probability distributions of clicks. The quest to understand the occurrence of the click in terms of the evolution of the wave function loses its meaning. However, click distributions in low resolution can be analyzed in terms of the connection between click distributions for different sets of counters, as given by the wave function. With increasing resolution, the probabilities, and the wave function, gradually lose significance, whereby the onset remains beyond reach. Thus, the downward path from events on the spacetime scene does not extend beyond the onset. The notion that quantum mechanics deals with particles (or fields) is rooted in the historical evolution but appears unable to accomodate genuine fortuitousness. The latter concept is given its due place by fully accepting the abstract nature of the matrix variables. (shrink)

Anti-exceptionalism about logic is the Quinean view that logical theories have no special epistemological status, in particular, they are not self-evident or justified a priori. Instead, logical theories are continuous with scientific theories, and knowledge about logic is as hard-earned as knowledge of physics, economics, and chemistry. Once we reject apriorism about logic, however, we need an alternative account of how logical theories are justified and revised. A number of authors have recently argued that logical theories are justified by abductive (...) argument (e.g. Gillian Russell, Graham Priest, Timothy Williamson). This paper explores one crucial question about the abductive strategy: what counts as evidence for a logical theory? I develop three accounts of evidential confirmation that an anti-exceptionalist can accept: (1) intuitions about validity, (2) the Quine-Williamson account, and (3) indispensability arguments. I argue, against the received view, that none of the evidential sources support classical logic. (shrink)

Craig Callender, Jonathan Cohen and Markus Schrenk have recently argued for an amended version of the best system account of laws – the better best system account (BBSA). This account of lawhood is supposed to account for laws in the special sciences, among other desiderata. Unlike David Lewis's original best system account of laws, the BBSA does not rely on a privileged class of natural predicates, in terms of which the best system is formulated. According to the BBSA, a contingently (...) true generalization is a law of a special science S iff the generalization is an axiom (or a theorem) of the best system relative to the set of predicates used by special science S. We argue that the BBSA is, at best, an incomplete theory of special science laws, as it does not account for typical features of special science laws, such as attached ceteris paribus conditions and the idealized character of law statements in these disciplines.

This chapter looks at Euler’s relation to Newton, and at his role in the rise of ‘Newtonian’ mechanics. It aims to give a sense of Newton’s complicated legacy for Enlightenment science, and to raise awareness that some key ‘Newtonian’ results really come from Euler.

In recent years a growing number of scholars in science studies and related fields are developing new ontologies to displace entrenched dualisms. These efforts often go together with a renewed interest in the roles played by symbolisms and tools in knowledge and being. This article brings Maurice Merleau-Ponty into these conversations, positioning him as a precursor of today’s innovative recastings of technoscience. While Merleau-Ponty is often invoked in relation to his early work on the body and embodiment, this article focuses (...) on his later work, where the investigation of perception is integrated with an ontological exploration. The resulting approach revolves around the highly original idea of the body as a standard of measurement. We further develop this idea by coining the term ‘the measuring body’, which to a greater extent than did Merleau-Ponty accentuates the relative autonomy of symbolisms and tools and their capacity to decentre the perceiving body.

This paper asks how anti-nuclear activists form collectives that are able to act collectively. It argues that shared interests and collective identities only insufficiently explain the emergence of collective action. Alternatively, the paper investigates meeting talk of German anti-nuclear groups where activists discuss proposals for collective action. Based on audio recordings, a sequential analysis of activists’ deliberations traces the transformation of vague ideas into concrete and collectively agreed to proposals. It is shown how the process by which activists reach a (...) common understanding about a particular protest activity—as something that is being talked about here and now—and the process of becoming an acting collectivity—a group that is ready to carry out this protest activity in the future—are interdependent. Activists make use of “indexicality” to introduce specifically vague proposals, enabling others to respond and contribute to the emerging proposal while group agency is suspended. At first, the authorship of proposals is minimized. Step by step, vague proposals are specified by meeting participants until a “change in footing” marks group consensus. While the group emerges as the author and principal of proposals through this process, the paper shows that implementation relies on individual principals again who take responsibility during and after the meeting.

Bitcoin is a peer-to-peer electronic payment system that operates as an independent currency. This paper is a philosophical investigation of the ontological constitution of Bitcoin. Using Slavoj Žižek’s ontological triad of the real, the symbolic and the imaginary, the paper distinguishes between three ideal typical theories of money: commodity theory, fiat theory, and credit theory. The constitution of Bitcoin is analysed by comparing the currency to each of these ideal types. It is argued that Bitcoin is commodity money without gold, (...) fiat money without a state, and credit money without debt. In conclusion, it is suggested that Bitcoin poses an ideological challenge to conventional forms of money in so far as it not only provokes sedimented beliefs about money but also exposes the forms of exploitation, risk and even violence inherent in the existing system of state authorized credit money.

Logical pluralism has been in vogue since JC Beall and Greg Restall 2006 articulated and defended a new pluralist thesis. Recent criticisms such as Priest 2006a and Field 2009 have suggested that there is a relationship between their type of logical pluralism and the meaning-variance thesis for logic. This is the claim, often associated with Quine 1970, that a change of logic entails a change of meaning. Here we explore the connection between logical pluralism and meaning-variance, both in general and (...) for Beall and Restall's theory specifically. We argue that contrary to what Beall and Restall claim, their type of pluralism is wedded to meaning-variance. We then develop an alternative form of logical pluralism that circumvents at least some forms of meaning-variance. (shrink)

ABSTRACTThis article offers a re-contextualization of the Positivism Dispute between the Frankfurt School and advocates of empirical sociology in the German sociological profession between 1954 and 1970. Investigating the reasons why the German Sociological Association convened in Tübingen in October 1961, it assigns a more peripheral role to Karl Popper and this now famous seminar. Focusing instead on the debate among German sociologists from the mid-1950s which prompted the convention of the seminar and the invitation for Popper to speak, the (...) article maintains that philosophy of history was the central concern of the Positivism Dispute. In this debate, members of the Frankfurt School emphasized contingency in history and society, while sociologists such as René König, Helmut Schelsky, Ralf Dahrendorf, and Arnold Gehlen advocated sociology as the empirical study of ‘given’ social facts. By doing so the article questions the narrative of the Positivism Dispute advanced by Karl Popper and some of his followers, as well as interpretations which have focused on debates during the aftermath of the Tübingen seminar in the 1960s.

The paper is a contribution to current debates about conspiracy theories within philosophy and cultural studies. Wittgenstein’s understanding of language is invoked to analyse the epistemological effects of designating particular questions and explanations as a ‘conspiracy theory’. It is demonstrated how such a designation relegates these questions and explanations beyond the realm of meaningful discourse. In addition, Agamben’s concept of sovereignty is applied to explore the political effects of using the concept of conspiracy theory. The exceptional epistemological status assigned to (...) alleged conspiracy theories within our prevalent paradigms of knowledge and truth is compared to the exceptional legal status assigned to individuals accused of terrorism under the War on Terror. The paper concludes by discussing the relation between conspiracy theory and ‘the paranoid style’ in contemporary politics. (shrink)

This book develops a new Wittgenstein interpretation called Wittgenstein’s Metametaphysics. The basic idea is that one major strand in Wittgenstein’s early and later philosophy can be described as undermining the dichotomy between realism and idealism. The aim of this book is to contribute to a better understanding of the relation between language and reality and to open up avenues of dialogue to overcome deep divides in the research literature. In the course of developing a comprehensive and in-depth interpretation, the author (...) provides fresh and original analyses of the latest issues in Wittgenstein scholarship and gives new answers to both major exegetical and philosophical problems. This makes the book an illuminating study for scholars and advanced students alike. (shrink)

ABSTRACT What do we disagree about when we disagree about logic? On the face of it, classical and nonclassical logicians disagree about the laws of logic and the nature of logical properties. Yet, sometimes the parties are accused of talking past each other. The worry is that if the parties to the dispute do not mean the same thing with ‘if’, ‘or’, and ‘not’, they fail to have genuine disagreement about the laws in question. After the work of Quine, this (...) objection against genuine disagreement about logic has been called the meaning-variance thesis. We argue that the meaning-variance thesis can be endorsed without blocking genuine disagreement. In fact, even the type of revisionism and nonapriorism championed by Quine turns out to be compatible with meaning-variance. (shrink)

In some philosophical arguments an important role is played by the claim that certain situations differ from each other with respect to phenomenology. One class of such arguments are minimal pair arguments. These have been used to argue that there is cognitive phenomenology, that high-level properties are represented in perceptual experience, that understanding has phenomenology, and more. I argue that facts about our mental lives systematically block such arguments, reply to a range of objections, and apply my critique to some (...) examples from the literature. (shrink)

This article contributes to contemporary philosophy of technology by carrying out a diffractive reading of Ernst Cassirer’s “Form und Technik” (1930) and Gilbert Simondon’s Du mode d’existence des objets techniques (1958). Both thinkers, who are here brought together for the first time, stood on the brink of the defining bifurcations of twentieth-century philosophy. However, in their endeavor to come to grips with the “being” of technology, Cassirer and Simondon, each in their own way, were prompted to develop an ontology of (...) emergence that gives ontological priority to “technicity,” that is, to technology considered in its efficacy or operative functioning. By reading Cassirer’s and Simondon’s insights through one another, we aim to further develop this ontology of emergence, and, simultaneously, to demonstrate the relevance of these thinkers for present-day theorizing. As we hope to show, the insistence on the ontological force of technological apparatuses transverses received philosophical and ontological divides and revitalizes the notions of “nature” and “the human,” which are now understood as coevolving with technology.

In bilateral systems for classical logic, assertion and denial occur as primitive signs on formulas. Such systems lend themselves to an inferentialist story about how truth-conditional content of connectives can be determined by inference rules. In particular, for classical logic there is a bilateral proof system which has a property that Carnap in 1943 called categoricity. We show that categorical systems can be given for any finite many-valued logic using $n$-sided sequent calculus. These systems are understood as a further development (...) of bilateralism—call it multilateralism. The overarching idea is that multilateral proof systems can incorporate the logic of a variety of denial speech acts. So against Frege we say that denial is not the negation of assertion and, with Mark Twain, that denial is more than a river in Egypt. (shrink)

In this thesis I seek to advance our understanding of what intuitions are. I argue that intuitions are experiences of a certain kind. In particular, they are experiences with representational content, and with a certain phenomenal character. -/- In Chapter 1 I identify our target and provide some important reliminaries. Intuitions are mental states, but which ones? Giving examples helps: a person has an intuition when it seems to her that torturing the innocent is wrong, or that if something is (...) red it is coloured. We can also provide an initial characterisation of the state by saying that it has representational content, often causes belief, and appears to justify belief. In addition, there is something it is like to have an intuition: intuition has a certain phenomenal character. -/- Some argue that intuition does not explain anything which cannot be explained by other mental states. One version of this view takes intuition to reduce to belief. In Chapter 2 I argue that this entails that agents are rationally criticisable in situations where we know they are not, and that such views are therefore untenable. A parallel argument shows that the corresponding approach to perception fails. This suggests a similarity in nature: both intuition and perception are experiences. -/- Others take intuition to reduce to a disposition to have a belief. In Chapter 3 I consider a line of argument against such views, find it unsuccessful, and present two new arguments. One is likely to be dialectically ineffective. The other suffers no such weakness: it shows that the proposed reduction fails. As before, the argument also applies to perception, and suggests that intuition and perception are both experiences. -/- In the remainder of the thesis I develop an account of intuition as an experience. I distinguish between content-specific and attitude-specific phenomenology, and argue that intuition lacks the former (Chapter 4), but has the latter (Chapter 5). This allows us to say what intuition is: it is is an experience with representational content and with attitude-specific phenomenology of a certain kind. -/- In Chapter 6 I put this account of intuition to use. When a person has a perceptual or intuitional experience, I argue that simply having the experience is what makes the subject justified in believing what the experience represents. Moreover, what explains that intuition and perception can justify belief in this way is precisely their phenomenal character. (shrink)

Nonclassical theories of truth have in common that they reject principles of classical logic to accommodate an unrestricted truth predicate. However, different nonclassical strategies give up different classical principles. The paper discusses one criterion we might use in theory choice when considering nonclassical rivals: the maxim of minimal mutilation.

Rational addiction theories illustrate how absurd choice theories in economics get taken seriously as possibly true explanations and tools for welfare analysis despite being poorly interpreted, empirically unfalsifiable, and based on wildly inaccurate assumptions selectively justified by ad-hoc stories. The lack of transparency introduced by poorly anchored mathematical models, the psychological persuasiveness of stories, and the way the profession neglects relevant issues are suggested as explanations for how what we perhaps should see as displays of technical skill and ingenuity are (...) allowed to blur the lines between science and games.

The standardised randomised clinical trial (RCT) has been exceedingly popular in medical research, economics, and practical policy making. Recently, RCTs have faced criticism. First, it has been argued by John Worrall that we cannot be certain that our sample is not atypical with regard to possible confounding factors. I will argue that at least in the case of medical research, we know enough about the relevant causal mechanisms to be justified to ignore a number of factors we have good reason (...) not to expect to be disruptive. I will also argue against an argument provided by Nancy Cartwright and Eileen Munro that RCTs should not be taken to deductively infer probabilistic causal claims, but ampliatively. The paper will end on a discussion of evidence hierarchies and a defence of the stance of evidence-based medicine that RCTs are the best available method to assess a treatment’s efficacy. (shrink)
