Recent discussions of emergence in physics have focussed on the use of limiting relations, and often particularly on singular or asymptotic limits. We discuss a putative example of emergence that does not fit into this narrative: the case of phonons. These quasi-particles have some claim to be emergent, not least because the way in which they relate to the underlying crystal is almost precisely analogous to the way in which quantum particles relate to the underlying quantum field theory. But there (...) is no need to take a limit when moving from a crystal lattice based description to the phonon description. Not only does this demonstrate that we can have emergence without limits, but also provides a way of understanding cases that do involve limits. (shrink)

Whether or not quantum physics can account for molecular structure is a matter of considerable controversy. Three of the problems raised in this regard are the problems of molecular structure. We argue that these problems are just special cases of the measurement problem of quantum mechanics: insofar as the measurement problem is solved, the problems of molecular structure are resolved as well. In addition, we explore one consequence of our argument: that claims about the reduction or emergence of molecular structure (...) cannot be settled independently of the choice of a particular resolution to the measurement problem. Specifically, we consider how three standard putative solutions to the measurement problem inform our under- standing of a molecule in isolation, as well as of chemistry’s relation to quantum physics.

It is commonly claimed that the universality of critical phenomena is explained through particular applications of the renormalization group. This article has three aims: to clarify the structure of the explanation of universality, to discuss the physics of such RG explanations, and to examine the extent to which universality is thus explained. The derivation of critical exponents proceeds via a real-space or a field-theoretic approach to the RG. Building on work by Mainwood, this article argues that these approaches ought to (...) be distinguished: while the field-theoretic approach explains universality, the real-space approach fails to provide an adequate explanation.

The modern Everett interpretation of quantum mechanics describes an emergent multiverse. The goal of this paper is to provide a perspicuous characterisation of how the multiverse emerges making use of a recent account of (weak) ontological emergence. This will be cashed out with a case study that identifies decoherence as the mechanism for emergence. The greater metaphysical clarity enables the rebuttal of critiques due to Baker (2007) and Dawid and Th\'ebault (2015) that cast the emergent multiverse ontology as incoherent; responses (...) are also offered to challenges to the Everettian approach from Maudlin (2010) and Monton (2013).

We present results from a single case study based on semi-structured interviews with a student (a boy in school year 3) diagnosed with autism spectrum disorder and his school staff after participating in a short and small-scale intervention carried out in a socio-economically disadvantaged Swedish elementary school in 2019. The student participated in a seven week long intervention with a total of 12 philosophical dialogues (ranging from 45 to 60 minutes). Two facilitators, both with years of facilitation experience and teacher (...) degree and at least BA in philosophy, facilitated the majority of the dialogues and mainly followed a ”routine” procedure. The student was interviewed in direct connection to the end of the intervention about his experiences from the dialogues and his perceptions about whether and how the dialogues had influenced him. The student’s two teachers, who had participated in the dialogues as participants, were interviewed as a pair, also in direct connection to the end of the intervention, while the school principal was interviewed two years after the study. These staff interviews concerned the staff’s experiences of the influence of the dialogues on the students within the intervention as well as transfer effects to other contexts in school. The data from the study include detailed elaborations from a student perspective of different effects on the student’s communicative and cognitive development, which are in several respects supported also by staff reports. The results show that the student was able, interested, and willing to participate in philosophical dialogues, and our data point to several positive outcomes for the student in the communicative and cognitive domains.

Many philosophers of science are ontologically committed to a lush rainforest of special science entities ), but are often reticent about the criteria that determine which entities count as real. On the other hand, the metaphysics literature is much more forthcoming about such criteria, but often links ontological commitment to irreducibility. We argue that the irreducibility criteria are in tension with scientific realism: for example, they would exclude viruses, which are plausibly theoretically reducible and yet play a sufficiently important role (...) in scientific accounts of the world that they should be included in our ontology. In this paper, we show how the inhabitants of the rainforest can be inoculated against the eliminative threat of reduction: by demonstrating that they are emergent. According to our account, emergence involves a screening off condition as well as novelty. We go on to demonstrate that this account of emergence, which is compatible with theoretical reducibility, satisfies common intuitions concerning what should and shouldn't count as real: viruses are emergent, as are trouts and turkeys, but philosophically gerrymandered objects like trout-turkeys do not qualify.

The universality of critical phenomena is best explained by appeal to the Renormalisation Group (RG). Batterman and Morrison, among others, have claimed that this explanation is irreducible. I argue that the RG account is reducible, but that the higher-level explanation ought not to be eliminated. I demonstrate that the key assumption on which the explanation relies – the scale invariance of critical systems – can be explained in lower-level terms; however, we should not replace the RG explanation with a bottom-up (...) account, rather we should acknowledge that the explanation appeals to dependencies which may be traced down to lower levels.

Multiple realisation prompts the question: how is it that multiple systems all exhibit the same phenomena despite their different underlying properties? In this paper I develop a framework for addressing that question and argue that multiple realisation can be reductively explained. I illustrate this position by applying the framework to a simple example – the multiple realisation of electrical conductivity. I defend my account by addressing potential objections:contra Polger and Shapiro, Batterman, and Sober, I claim that multiple realisation is commonplace, (...) that it can be reductively explained, but that it requires asui generisreductive explanatory strategy.

Broadly construed, moral sentimentalism is the position that human emotions or sentiments play a crucial role in our best normative or descriptive accounts of moral value or judgments thereof. In this paper, I introduce and sketch a defense of a new form of moral sentimentalism I call “Transcendental Sentimentalism”. According to transcendental sentimentalism, having a sentimental response to an object is a necessary condition of the possibility of a subject counting as having non-inferential evaluative knowledge about that object. In unpacking (...) each component of this position, I argue that it is both distinct from and more explanatorily attractive than the other approaches to explaining the relationship between emotion and moral thought, including what Kauppinen (2014, forthcoming) calls epistemological sentimentalism and explanatory sentimentalism. I conclude by offering a sketch of what I take to be the most promising strategy for demonstrating the truth of transcendental sentimentalism, suggesting an original form of transcendental argument. If successful, this form of argument would establish transcendental sentimentalism by demonstrating that not having a sentimental response to x disqualifies (in the normative sense) a person from counting as having non-inferential evaluative knowledge of x.

The aim of this work is to demarcate, develop, and defend the commitments and consequences of metaethical minimalism. Very roughly, this is the position that a commitment to objective moral truths does not require any accompanying ontological commitments. While there are few, if any, who call themselves “metaethical minimalists”, I endeavor to uncover existing articulations of metaethical minimalism which have been presented under different names, attempting to identify the common ground between them. As I interpret the position, all metaethical minimalists (...) are committed to the same positive pair of claims (what I call the Objectivity Thesis): “a) Moral truths are strongly mind-independent; b) there are moral truths.” Taken by itself, however, this pair of claims is not sufficient for differentiating their view from the moral realist’s. Consequently, the minimalist must also articulate that which they are denying about the non-minimalist approach, or what I call the “negative ontological thesis”. I offer my own version of this negative thesis and argue for its dialectical advantages. -/- In Chapters 3 and 4, I focus my attention on attacks on the viability of metaethical minimalism in the form of two “challenges” that aim to problematize a commitment to objective moral truths absent any accompanying ontological commitment. The big-picture takeaway from these chapters is that minimalism can defend itself by playing to the dialectical advantage I find for it in Chapter 2 as well as by being creative about minimalist constructions/reworkings of plausible principles/lines of reasoning that seem to contradict it. -/- The temptation to embrace quietism is strong among minimalists, but in Chapters 5, 6, and 7 I aim to show that there is a positive alternative available for the minimalist interested in developing a full picture of their position. Chapter 5 is aimed at providing an adequate understanding of the distinction between the objects of purely normative thoughts and objects of thoughts about reality. Building on this are Chapters 6 and 7, which argue in favor of an account of the relationship between emotion and evaluative knowledge that is consistent with metaethical minimalism. (shrink)
