The goal of this essay is twofold. First, it provides a quick look at the foundations of modern relational mechanics by tracing its development from Julian Barbour and Bruno Bertotti's original ideas until present-day's pure shape dynamics. Secondly, it discusses the most appropriate metaphysics for pure shape dynamics, showing that relationalism is more of a nuanced thesis rather than an elusive one. The chapter ends with a brief assessment of the prospects of pure shape dynamics in light of quantum physics.

We present a new metaphysical framework for physics that is conceptually clear, ontologically parsimonious, and empirically adequate. This framework relies on the notion of self-subsisting structure, that is, a set of fundamental physical elements whose individuation and behavior are described in purely relational terms, without any need for a background spacetime. Although the specification of the fundamental elements of the ontology depends on the particular physical domain considered---and is thus susceptible to scientific progress---, the empirically successful structural features of the (...) framework are preserved through theory change. The kinematics and dynamics of these self-subsisting structures are technically implemented using the theoretical framework of Pure Shape Dynamics, which provides a completely relational physical description of a system in terms of the intrinsic geometry of a suitably defined space called shape space.

The paper presents an extension of the metaphysics of self-subsisting structures set out in a companion paper to the realm of non-relativistic quantum physics. The discussion is centered around a Pure Shape Dynamics model representing a relational implementation of a de Broglie-Bohm N-body system. An interpretation of this model in terms of self-subsisting structures is proposed and assessed against the background of the debate on the metaphysics of quantum physics, with a particular emphasis on the nature of the wave function. (...) The analysis shows that elaborating an appropriate Leibnizian/Machian metaphysics of the quantum world requires a substantial revision of the notion of world-building relation. (shrink)

We asked college students to make judgments about realistic moral situations presented as dilemmas (which asked for an either/or decision) vs. problems (which did not ask for such a decision) as well as when the situation explicitly included affectively salient language vs. non-affectively salient language. We report two main findings. The first is that there are four different types of cognitive strategy that subjects use in their responses: simple reasoning, intuitive judging, cautious reasoning, and empathic reasoning. We give operational definitions (...) of these types in terms of our observed data. In addition, the four types characterized strategies not only in the whole sample, but also in all of the subsamples in our study. The second finding is that the intuitive judging type comprised approximately 26% of our respondents, while about 74% of our respondents employed one of the three styles of reasoning named above. We think that these findings present an interesting challenge to models of moral cognition which predict that there is either a single, or a single most common, strategy – especially a strategy of relying upon one’s intuitions – that people use to think about moral situations.

In this wide-ranging interview with three members of the Department of Philosophy at the University of Sao Paolo (Brazil) Wylie explains how she came to work on philosophical issues raised in and by archaeology, describes the contextualist challenges to ‘received view’ models of confirmation and explanation in archaeology that inform her work on the status of evidence and contextual ideals of objectivity, and discusses the role of non-cognitive values in science. She also is pressed to explain what’s feminist about feminist (...) research and in that connection outlines her account of feminist standpoint theory and the relevance of feminist analysis to science.

The concept of modes of existence of semiotic entities underlies (post)Greimasian semiotics, yet it seems to have received little attention. Modes of existence can be used in different senses. For Greimas, from the perspective of narrative semiotics, when Michelangelo first receives a block of marble and decides to sculpt the David, his intention is in a virtual mode; as Michelangelo progresses he ends up bringing the David into existence, and his intention comes to the realized mode. In Fontanille’s tensive semiotics, (...) however, modes of existence can have to do with how one can narrow or broaden the scope of our apprehension of the David as our eyes look at it in order to produce a meaningful experience. In this work, the perspectives of narrative and tensive semiotics are contrasted both theoretically and practically applying both to a number of examples. In order to identify all possible modes of existence and all the possibilities of transitioning from one to the other in the examples presented, we resort to the method of finite-state automata from computer science. In the end, we propose a robust narrative account of modes of existence that relies on narrative semiotics for its definition, but into which intent and apprehension from tensive semiotics can be integrated. This work calls for the need of establishing a syntax of modes of existence, since both Greimas and Fontanille construe them as being necessary to account for the production of signification.

In reading Barbara Koslowski's "Theory and Evidence: The Development of Scientific Reasoning", one may be convinced that the ancient debate between classical rationalists and empiricists is alive. And like most people who carefully investigate the ability of either rationalism or empiricism truly to account for all of our ability to know, Koslowski arrives at the position of saying that knowledge (in this case scientific knowledge) is a product of both: "neither theory nor data alone is sufficient to achieve (...) scientific success; each must be evaluated in the context of, and constrained by, the other". The problem, according to Koslowski, for those who insist upon empiricism as being the only type of understanding which counts as science, is that we then exclude much of the productive thought in children empiricism champions itself as being theory-independent. The theory-independent notion of science uses covariation as its exclusive criterion for scientific reasoning. "In short, the empiricist aim of rationally reconstructing scientific inquiry in terms of theory-independent principles went along with an (all but exclusive) emphasis on the role of Humean indices. And this, in turn, brought with it a corresponding emphasis on hypothesis testing rather than hypothesis discovery and revision". Consequently, according to Koslowski, if we are willing to expand our notion of scientific reasoning to go beyond testing for covariation, then we will find that many more children and adults can be seen to reason in a manner which would be called "scientific".

In this paper, I engage with the motif of “the pluriverse” such as it has increasingly been used in the past few years in several strands of critical humanities pertaining to the so-called “ontological turn”: science and technology studies (Bruno Latour, Isabelle Stengers), critical geography and political ontology (Mario Blaser), cultural anthropology (Marisol de la Cadena, Arturo Escobar, Eduardo Viveiros de Castro), decolonial thought (Walter Mignolo), or posthuman feminism (Donna Haraway). These various iterations of the figure of the pluriverse (...) constitute a loose network of textual traces, a supposedly new scene for ‘humanities’, organized around what is understood as a pluralistic ontology. In political terms, the discourse of the pluriverse presents itself as a strategic response to the violence of universalism. It advocates for a multiversal ethics, a pluriversal cosmopolitics based on interspecies and multi-natural kinships, and more aware of the multiplicity of worlds and world-making practices that make up the post-globalization scene. Based on readings of Bruno Latour, Eduardo Viveiros de Castro, Arturo Escobar and Marisol de la Cadena among others, I argue that the notion of pluriversality remains self-contradictory and self-defeating as long as it relies on an ontological representation of world/worlds in the form of copresence. Drawing on Derrida’s deconstruction of the concept of world (cosmos, mundus) in his late writings, I propose to think an exorbitant plurality, before the pluriverse and before being. Beyond ontological pluralism, Derrida’s “infinity of untranslatable worlds” also signifies an irreducible interruption, the end of the world, of any “world-in-common”, thus raising the stakes for the ethical demand towards the other.
