The identity of indiscernibles states that indiscernible objects must be identical. Many philosophers have held that the PII turns out to be either true but trivial, or non-trivial but false, depending on how the notion of discernibility is spelled out. In this paper, I propose and defend an account of this notion which aims to yield a minimally non-trivial and yet plausible version of the PII. I argue moreover that this version of the principle is immune to a number of (...) well-known and recent objections to the PII. (shrink)

In this paper I examine Locke’s criticism of the view that some species of natural objects are determined by real essences, a view I call species realism. Most commentators have focused either on Locke’s putative objections to the realist’s claim that species determining real essences exist or on his semantic case against the assumption that our species terms can refer to real essences that determine species. I identify another objection, which, I argue, is independent from both of these lines of (...) criticism. This objection is essentially practical. It is based on the claim that adopting species realism has detrimental practical consequences: it undermines, Locke believes, our ability to sort particular natural objects into species. This alone, he argues, is already sufficient to set aside and ignore species realism when trying to sort objects into species. (shrink)

John Locke famously claimed that our idea of substance is but a confused idea of “something we know not what.” However, he also thought that the idea of substance is a fundamental part of our ideas of ourselves and the objects surrounding us—of objects we do know. Interpreting this apparently ambivalent stance has long been a major challenge for Locke scholarship. In this article, I argue that the leading interpretations of Locke's conception of substance have failed to resolve this tension (...) because they have misconstrued the source of Locke's skepticism about our knowledge of what substance is. This skepticism, I argue, issues from an observation about the signification of the term “substance”: Locke maintained that the philosophical usage of the term is irremediably equivocal. This reading allows us to acknowledge that Locke could consistently hold that ordinary objects, such as persons, horses, or trees, are paradigmatic examples of substances. It also points to a better appreciation of how Locke's discussion of substance relates to the scholastic conceptions of substance he tried to overcome. (shrink)

I argue that Locke’s distinction between ‘determined’ and ‘undetermined’ ideas incorporates an account of semantic indeterminacy: if the complex idea to which a general term is annexed is ‘undetermined’, the term lacks a determinate extension. I propose that a closer look at this account of semantic indeterminacy illuminates various charges of confusion, misuse and abuse of language Locke levels against his philosophical contemporaries.

Debates that revolve around the topic of morality and fiction rarely explicitly treat virtual worlds like, for example, Second Life. The reason for this disregard cannot be that all users of virtual worlds only do the right thing while online—for they sometimes even virtually kill each other. Is it wrong to kill other people in a virtual world? It depends. This essay analyzes on what it depends, why it is that killing people in a virtual world sometimes is wrong, and (...) how different virtual killings are wrong in different ways. I argue that killing people online is wrong if it is an instance of deliberately and non-consensually evoking disagreeable emotions in others. Establishing this conclusion requires substantial conceptual work, as virtual worlds feature new kinds of fictional agency, particular emotional responses to fiction, and unique ways in which the fiction of the virtual world relates to the wrongness of the killing.

This essay examines three potential arguments against high-frequency trading and offers a qualified critique of the practice. In concrete terms, it examines a variant of high-frequency trading that is all about speed—low-latency trading—in light of moral issues surrounding arbitrage, information asymmetries, and systemic risk. The essay focuses on low-latency trading and the role of speed because it also aims to show that the commonly made assumption that speed in financial markets is morally neutral is wrong. For instance, speed is a (...) necessary condition for low-latency trading’s potential to cause harm in “flash crashes.” On the other hand, it also plays a crucial role in a Lockean defense against low-latency trading being wasteful developed in this essay. Finally, this essay discusses the implications of these findings for related high-frequency trading techniques like futures arbitrage or latency arbitrage—as well as for an argument as to why quote stuffing is wrong. Overall, the qualifications offered in this essay act as a counterbalance to overblown claims about trading at high speeds being wrong. (shrink)

Judging on the basis of standard accounts of commodification, one might reasonably suggest that liberalism intrinsically lacks an adequate theory of commodification. Liberalism, with its commitment to individual choice and to neutrality as regards competing evaluation practices, seems conceptually incapable of identifying or abolishing many significant forms of commodification. This essay aims to refute this claim. It employs a strategy of appealing to the harm principle as grounds for a liberal anti-commodification theory. I claim that we are harmed when we (...) are denied ways to meaningfully engage in certain evaluative practices, ways that depend on evaluations shared with others with whom we stand in meaningful social relationships. Markets can crowd out these shared evaluations, and to this extent cause us psychological harm; this in turn supplies grounds for restrictions on certain markets within a liberal state. (shrink)

This essay examines a new way to exercise democratic control over the market. Instead of a democratic government interfering with a market’s outcomes (e.g. via taxes or minimum wages), we may also “democratize” the market by requiring that all relevant group agents who participate in that market (notably: firms) be democratically governed. This is what I call an agent-democratic market. The purpose of this essay is to argue for the claim that agent-democratic markets are a normatively viable way to democratize (...) the market – and potentially constitute a genuine alternative to the standard approach of subjecting market outcomes to democratic control. (shrink)

In this paper, I am concerned with what automation—widely considered to be the “future of work”—holds for the artificially intelligent agents we aim to employ. My guiding question is whether it is normatively problematic to employ artificially intelligent agents like, for example, autonomous robots as workers. The answer I propose is the following. There is nothing inherently normatively problematic about employing autonomous robots as workers. Still, we must not put them to perform just any work, if we want to avoid (...) blame. This might not sound like much of a limitation. Interestingly, however, we can argue for this claim based on metaphysically and normatively parsimonious grounds. Namely, all I rely on when arguing for my claim is that the robots we aim to employ exhibit a kind of autonomy. (shrink)

This paper analyses the emergence and persistence of disorder due to bellicose (i.e. ‘conflict-kindling’) institutions. It does so relying on a novel empirical approach, examining the predatory and productive interactions of 400,000 users of a virtual world as well as its institutions. The paper finds that while there are many cases of spontaneous order in that virtual world, and while the users are not more conflict-loving as such, bellicose institutions sanctioning suicidal attacks in a supposedly safe region spontaneously emerged and (...) rigidly persist, thus upholding disorder (i.e. a particularly violent kind of ordered anarchy).

This essay argues that prediction markets, as one approach for aggregating dispersed private information, may not only be praised for their epistemic accuracy. They also feature characteristics that are morally desirable from the point of view of epistemic justice. Notably, they are a promising approach when we are trying to address testimonial injustice. The impersonality of market transactions effectively tackles the issue of identity prejudice, which underlies many forms of testimonial injustice. This is not to say that prediction markets do (...) not pose challenges for epistemic justice of their own like the risk of excluding knowers based on ability to pay. Or, in light of identity prejudice’s systematicity, the risk of discouraging some knowers because of differences in education or social background that lead to a certain unease when faced with prediction markets. The essay discusses these challenges, concedes limitations but also offers countermeasures to certain worries – e.g. hosting prediction markets on a play-money basis. Throughout, the essay addresses the question of the potential scope of using prediction markets for epistemic purposes, notably by means of the practical example of a prediction market for monetary policy.

The definition of ‘patient’ is commonly taken for granted and considered as obvious, but the term is rather underconceptualised in the literature. In this paper, it will be argued that the criterion of suffering can be considered a sufficient criterion for a parent to be considered a secondary patient when their seriously ill child is receiving medical care (i.e. not necessarily the parents themselves) – these parents are sufferers in virtue of the suffering of others. The nature of parental and (...) child health and well-being is clearly relational and bidirectional, thus also a bidirectional and relational integration of parental and paediatric patient care is necessary. A genuine expansion of the concept ‘patient’ to parents, both practically and theoretically, can help to bring awareness to the closely intertwining, interacting and interdependent vulnerabilities of both parties, the potential conflicts of interests involved, and also to demand support and reduce hurdles, for example, in reimbursement by health insurers. Treating parents as patients will (1) help the affected child (the primary patient), as unhealthy and/or mentally unstable parents are likely to negatively influence a child's treatment and (2) prevent the parents (the secondary patients) from becoming primary patients themselves due to their suffering because of their child's illness.

Language’s intentional nature has been highlighted as a crucial feature distinguishing it from other communication systems. Specifically, language is often thought to depend on highly structured intentional action and mutual mindreading by a communicator and recipient. Whilst similar abilities in animals can shed light on the evolution of intentionality, they remain challenging to detect unambiguously. We revisit animal intentional communication and suggest that progress in identifying analogous capacities has been complicated by (i) the assumption that intentional (that is, voluntary) production (...) of communicative acts requires mental-state attribution, and (ii) variation in approaches investigating communication across sensory modalities. To move forward, we argue that a framework fusing research across modalities and species is required. We structure intentional communication into a series of requirements, each of which can be operationalised, investigated empirically, and must be met for purposive, intentionally communicative acts to be demonstrated. Our unified approach helps elucidate the distribution of animal intentional communication and subsequently serves to clarify what is meant by attributions of intentional communication in animals and humans.

How do we change the normative landscape by making requests? It will be argued that by making requests we create reasons for action if and only if certain conditions are met. We are able to create reasons if and only if doing so is valuable for the requester, and if they respect the requestee. Respectful requests have a normative force – it will be argued – because it is of instrumental value to us that we all have the normative power (...) of creating reasons by making requests. The normative power has the potential for creating and shaping valuable interactions and relationships for the requester and the requestee. This potential could not be realized if we did not have the normative power of making requests. It will also be shown why this account of the normative force of requests should be preferred to the two alternative accounts of the reason-giving force of requests that have been put forward by James H.P. Lewis and David Enoch. (shrink)

Since the early days of economics, the rationality principle has been a core element of economic theorizing. It is part of almost any theoretical framework that economists use to generate knowledge. Despite its central role, the principle’s epistemic status and function continue to be debated between empiricists and rationalists, and a clear winner is yet to emerge. One point of contention is that we cannot explain the principle’s special status in light of clear evidence against its empirical validity and the (...) continuous conceptual changes it undergoes. In this paper, I argue that we should think of the rationality principle as a functional a priori principle along the lines of a pragmatic theory of constitutive elements recently put forward by David Stump. Such an approach would explain the principle’s persistence and changing status. More generally, the pragmatic theory of constitutive elements in science offers a viable alternative to rationalism and empiricism that allows for approaching the debate about the status and function of the rationality principle in economics. It provides a new framework and starting point to think about the usefulness of a central first principle in economics in a constructive way. (shrink)

In June 2016, David Chalmers delivered the Petrus Hispanus Lectures at the LanCog research group, University of Lisbon, on the subject of objects, properties, and perception in virtual reality environments. The paper resulting from these lectures was subsequently published in Disputatio as “The Virtual and the Real” (vol. IX, 2017, No. 46, pp. 309–52). In it, Chalmers defends virtual realism, according to which virtual objects are bona fide digital objects with virtual counterparts of perceptible properties such as colour and (...) shape, and perception in virtual reality environments is typically veridical rather than illusory. This special issue collects responses to Chalmers due to Claus Beisbart, Jesper Juul, Peter Ludlow, Neil McDonnell and Nathan Wildman, Alyssa Ney, Eric Schwitzgebel, and Marc Silcox; together with a detailed response by Chalmers to each paper.

Many political philosophers hold the Feasible Alternatives Principle (FAP): justice demands that we implement some reform of international institutions P only if P is feasible and P improves upon the status quo from the standpoint of justice. The FAP implies that any argument for a moral requirement to implement P must incorporate claims whose content pertains to the causal processes that explain the current state of affairs. Yet, philosophers routinely neglect the need to attend to actual causal processes. This undermines (...) their arguments concerning moral requirements to reform international institutions. The upshot is that philosophers’ arguments must engage in causal analysis to a greater extent than is typical. -/- [Supplement: Handout available at http://db.tt/fyuVW3Xv]. (shrink)

This is a book about evolution from a post-Darwinian perspective. It recounts the core ideas of French philosopher Henri Bergson and his rediscovery and legacy in the poststructuralist critical philosophies of the 1960s, and explores the confluences of these ideas with those of complexity theory in environmental biology. The failings in the development of systems theory, many of which complex systems theory overcomes, are retold; with Bergson, this book proposes, some of the rest may be overcome too. It asserts that (...) Bergson’s ideas can further our understanding of evolution, and of complex systems, and aid the work of scientists working in the field of ecological complexity. See http://www.creativeemergence.info/ for more detail and sample chapter. "The claim is that Bergson's notions of duration and élan vital resonate with and provide interesting metaphysical speculations complementing a process structuralist biology of the Goodwin and Kauffman stripe. This is certainly provocative and worth further thought. The key claim is that the openness and unpredictability of systems "at the edge of chaos" (where a system can be said to "choose" at bifurcation points in its state space) meets the Bergsonian desideratum of an open universe that takes irreversible time and evolutionary difference seriously. In particular, Kreps stresses the way Bergson's insistence on the differentiating force of élan vital (which Kreps successfully defends from the charge of a substantialist vitalism along the lines of Hans Dreisch) puts him in line with those who see natural selection as a secondary pruning of a primary differentiation." -John Protevi, Notre Dame Philosophical Reviews 2016.01.20 'This is no ordinary introduction to Henri Bergson. What David Kreps' excellent study gives us is Bergson, complexe: first, because there is no simple way to take (or leave) Bergson's ideas - his thought of durée, élan, and 'multiplicity' demands the most subtle and nuanced reading to give them their full justice; and second, because only by intertwining his ideas with the most up-to-date research in systems thinking, complexity theory, and poststructuralism can we begin to understand their absolute contemporaneity. Kreps' work does all this and more: it gives us the Bergson we need for today.' -John Mullarkey, author of Bergson and Philosophy 'Kreps' book is a thoroughly researched and well-written work that shows how Bergson's philosophy of evolution and time can also reinvigorate our ideas about complexity and organization in the natural and physical sciences.' -Stephen Crocker, author of Bergson and the Metaphysics of Media.

It's very interesting to see neurophysiological evidence brought to bear on the puzzling question of conscious experience. Many have observed that information-processing models of cognition seem to leave consciousness untouched; it is natural to hope that turning to neurophysiology might lead us to the Holy Grail. Still, I think there are reasons to be skeptical. There are good reasons to suppose that neurophysiological investigation contributes to cognitive explanation at best in virtue of constraining the information-processing structure of cognition. Of course (...) this is a very large and significant role for it to play, but it may be over-optimistic to suppose that it can play some further explanatory role, taking us where information-processing theories cannot. If so, then neurophysiological accounts will be no more and no less successful at dealing with consciousness than information-processing accounts are. (shrink)

1. I think that by emphasizing theoretical spaces of representations, Andy has put his finger on an issue that is key to connectionism's success, and whose investigation will be a key determinant of the field's further progress. I also think that if we look at representational spaces in the right way, we can see that they are deeply related to classical phenomenon of systematicity in representation. I want to argue that the key to understanding representational spaces, and in particular their (...) ability to capture the deep organization underlying various problems, lies in the idea of what I will call.

Does 'Person P tried to A' entail that there is some particular, whether a mental act or a brain state or whatever, that is a trying? Most discussions of trying assume that this entailment holds. There is no good reason for holding that this is a valid inference. In particular, I examine one 'Davidsonian' argument that might be used to justify the validity of such an inference and argue that the argument is not sound.
