Several authors have made claims about the compatibility between the Free Energy Principle and theories of autopoiesis and enaction. Many see these theories as natural partners or as making similar statements about the nature of biological and cognitive systems. We critically examine these claims and identify a series of misreadings and misinterpretations of key enactive concepts. In particular, we notice a tendency to disregard the operational definition of autopoiesis and the distinction between a system’s structure and its organization. Other misreadings (...) concern the conflation of processes of self-distinction in operationally closed systems and Markov blankets. Deeper theoretical tensions underlie some of these misinterpretations. FEP assumes systems that reach a non-equilibrium steady state and are enveloped by a Markov blanket. We argue that these assumptions contradict the historicity of sense-making that is explicit in the enactive approach. Enactive concepts such as adaptivity and agency are defined in terms of the modulation of parameters and constraints of the agent-environment coupling, which entail the possibility of changes in variable and parameter sets, constraints, and in the dynamical laws affecting the system. This allows enaction to address the path-dependent diversity of human bodies and minds. We argue that these ideas are incompatible with the time invariance of non-equilibrium steady states assumed by the FEP. In addition, the enactive perspective foregrounds the enabling and constitutive roles played by the world in sense-making, agency, development. We argue that this view of transactional and constitutive relations between organisms and environments is a challenge to the FEP. Once we move beyond superficial similarities, identify misreadings, and examine the theoretical commitments of the two approaches, we reach the conclusion that far from being easily integrated, the FEP, as it stands formulated today, is in tension with the theories of autopoiesis and enaction.

The philosophical analysis of mathematical explanations concerns itself with two different, although connected, areas of investigation. The first area addresses the problem of whether mathematics can play an explanatory role in the natural and social sciences. The second deals with the problem of whether mathematical explanations occur within mathematics itself. Accordingly, this entry surveys the contributions to both areas, it shows their relevance to the history of philosophy and science, it articulates their connection, and points to the philosophical pay-offs to (...) be expected by deepening our understanding of the topic.

That words express a conceptual content is uncontroversial. This does not entail that their content should break down neatly into a grammatical part, relevant for language and to be analyzed in linguistic terms, and a conceptual part, relevant for cognition and to be analyzed in psychological terms. Various types of empirical evidence are reviewed, showing that the conceptual content of words cannot be isolated from their linguistic properties, because it is affected and shaped by them. The view of words as (...) labels or containers for a non-linguistic conceptual content stems from a naive disregard of the complex and structured nature of lexical knowledge. On the contrary, knowledge of language is shown not just to organize and categorize conceptual content in a way not reducible to non-linguistic cognition, but also to affect its scope, as the range of verbalized concepts is both limited by abstract templates and expanded by productive word formation. This suggests that lexical knowledge is a distinctively linguistic dimension of conceptualization, and that words do not so much label or package concepts, as provide an inner form for conceptual knowledge.

Neuroeconomics, neuromarketing, neuroaesthetics, and neurotheology are just a few of the novel disciplines that have been inspired by a combination of ancient knowledge along with recent discoveries about how the human brain works.This fascinating and thought provoking new book critically questions our love affair with brain imaging.

This paper is the first of a series of three articles that present the syntactic proof of the PA-completeness of the modal system G, by introducing suitable proof-theoretic objects, which also have an independent interest. We start from the syntactic PA-completeness of modal system GL-LIN, previously obtained in [7], [8], and so we assume to be working on modal sequents S which are GL-LIN-theorems. If S is not a G-theorem we define here a notion of syntactic metric d(S, G): we (...) calculate a canonical characteristic fomula H of S (char(S)) so that ⊢G ∼ H → (∼S) and ⊢GL-LIN ∼ H, and the complexity σ of ∼ H gives the distance d(S, G) of S from G. Then, in order to produce the whole completeness proof as an induction on this d(S, G), we introduce the tree-interpretation of a modal sequent Q into PA, that sends the letters of Q into PA-formulas describing the properties of a GL-LIN-proof P of Q: It is also a d(*, G)-metric linked interpretation, since it will be applied to a proof-tree T of ∼ H with H = char(S) and σ(∼ H) = d(S, G).

Can governments keep the pace of global markets? It is a defining characteristic of the present times, tested and measured within multiple studies, that we are living in an increasingly interconnected economy in which giant companies emerge and compete presenting new goods and products at a global scale. The competing environment of international markets produces quickly growing creatures that old nation-states struggle to understand, monitor and, consequently, regulate. In this regard, the selection process taking place in the market seems to (...) be far more effective and greedy than the selection process we apply to our governments. In this paper I discuss the basic theoretical mechanisms for the persistence of wealth concentration, introducing a general game-theoretical framework to connect governance, market economy, and wealth distribution, and to rethink democracy and fairness in policy-making, especially with the aim of global sustainability governance.

In correspondence with Mersenne in 1629, Descartes discusses a construction involving a cylinder and what Descartes calls a “helice.” Mancosu has argued that by “helice” Descartes was referring to a cylindrical helix. The editors of Mersenne’s correspondence (Vol. II), and Henk Bos, have independently argued that, on the con- trary, by “helice” Descartes was referring to the Archimedean spiral. We argue that identifying the helice with the cylindrical helix makes better sense of the text. In the process we take a (...) careful look at constructions of the cylindrical helix available to Descartes and relate them to his criteria for excluding mechanical curves from geometry. Résumé Dans sa correspondance avec Mersenne en 1629, Descartes discute d’une construction qui fait intervenir un cylindre et ce que Descartes appelle une “hélice”. Mancosu a argumenté que Descartes faisait référence à une hélice cylindrique. Les éditeurs de la Correspondance de Mersenne (vol. 2), et Henk Bos, ont indépendamment affirmé que, au contraire, par “hélice” Descartes faisait référence à la spirale d’Archimède. Nous affirmons qu’identifier l’hélice avec l’hélice cylindrique est plus cohérent avec le texte. Dans le même temps nous examinons soigneusement les constructions de l’hélice cylindrique que Descartes avait à disposition et nous les mettons en relation avec son critère d’exclusion des courbes mécaniques de la géométrie.

Despite the substantial difference in their monetary theories, Menger and Keynes agree in terms of stigmatizing the love of money. This paper attempts to demonstrate that the shared ethical judgment is defensible for both on the grounds of the same metaethical assumptions—the value theory of Franz Brentano. The paper will be structured in two main parts: I. Ethics. The first part justifies the common rejection of the love of money, at the ethical level. This classical position, as a matter of (...) fact, is considered controversial: in the case of Menger, his criticism towards egoism seems not coherent with his alleged utilitarianism; in the case of Keynes, his disparaging remarks on the love of money as a disgusting morbidity seem in direct contradiction with his endorsement of capitalism. II. Metaethics. In the second part, the focus will be the Fitting Attitude Theory of value, namely with reference to Brentano. The objective will be to identify and discuss the Brentanian arguments by which Menger and Keynes defend their ethical rejection of the love of money. (shrink)

For Keynes, the history of money begins when the function of measure of value arises for the first time. By contrast, Menger believes that the origin of money is determined by the appearance of the function of medium of exchange. Despite this substantial difference in interpretation, Menger and Keynes agree in terms of criticizing the function of store of value, even though this third function is useful under certain conditions. This paper argues that this agreement, at the level of monetary (...) theory, is linked to a common ethical evaluation: Both stigmatise the love of money exactly because this desire involves a false absolutisation of money as a store of wealth. The paper will be structured in two main parts: I. Monetary Theory. The first part briefly sketches the two competing models of the explanation of the origin of money and its value. II. Ethics. In the second part, the focus will be the common rejection of the love of money. (shrink)

Nietzsche’s metaethics is a topic which, especially in the last decade, has gained ever increasing attention among Anglo-American Nietzsche-scholars. Conversely, this topic has been almost ignored by continental philosophers. This paper aims to give a general overview of the ongoing discussion, focusing on several problems originating from the attempt to give a coherent and non-contradictory picture of both Nietzsche’s negative and positive metaethical position. Attention will be first directed to Nietzsche’s moral perspectivism (1) and then to his alleged proto-error theory (...) (2). Subsequently, the focus will be on Nietzsche’s moral projectivism and the question of whether this position necessarily requires a non-cognitivist view of moral discourse (3). Finally, the last section will be devoted to a discussion of how to reconcile Nietzsche’s negative metaethics with his positive metaethics (4). (shrink)

It is usually maintained that a subject with manifestly contradictory beliefs is irrational. How can we account, then, for the intuitive rationality of dialetheists, who believe that some manifest contradictions are true? My paper aims to answer this question. Its ultimate goal is to determine a characterization of (or rather a constraint for) rational belief approvable by both the theorists of Dialetheism and its opponents. In order to achieve this goal, a two-step strategy will be adopted. First, a characterization of (...) rational belief applicable to non-dialetheist believers will be determined; this characterization will involve the semantic apparatus of Nathan Salmon’s Millian Russellianism but will get rid of the problematic and obscure notion of mode of presentation (guise in his own terminology), replacing it with a couple of novel devices, belief subsystems and cognitive coordination. Second, using ideas from Graham Priest, the leading proponent of Dialetheism, such a characterization will be modified, so as to devise a new one able to account for the intuitive rationality of both dialetheist and non-dialetheist believers.

In a recent paper, Christian List (2014) has argued for the compatibilism of free will and determinism. Drawing on a distinction between physical possibility (used in defining determinism) and agential possibility (used in defining free will), List constructs a formal two-level model in which the two concepts are consistent. This paper's first contribution is to show that though List's model is formally consistent, philosophically it falls short of establishing a satisfactory compatibilist position. Ensuingly, an analysis of the shortcomings of the (...) model leads to the identification of a controversial epistemological assumption implicit in the statements of both compatibilist and incompatibilist positions. Arguing that this assumption is not currently satisfied, the paper's second contribution is to show that neither the compatibilist nor the incompatibilist position is presently well-founded.

Since the early 1990s, an increasing number of troops have been deployed in peacekeeping missions all around the world. The mixed success and high-profile failures of several missions have provided peacekeepers and scholars with a wealth of experience from which to generate knowledge and understand key lessons. In this article I use the Rwandan case to explore the issue of the use of force to protect unarmed civilians that have become the target of violence. In particular, I focus on the (...) moral responsibilities implied in such operations. I contend that in order for peacekeepers to be effective, they need to subscribe to, and be motivated by a peacekeeper ethos. The core element of this ethos is the protection of human life. Those peacekeepers who, through experience and education, internalize this ethos will be the best prepared for the difficult task they face. This article emphasizes the importance of sharpening moral autonomy among peacekeepers, in order to provide them with the skills they need to be more effective in saving lives. To illustrate this point, I analyze the slaughter of more than 2000 refugees at the ETO school in Kigali, Rwanda; a UN site protected by Belgian peacekeepers in 1994. (shrink)

This article draws attention to several different practices of observation, manipulation, and experimentation with the surface of natural things. Beginning from the observation that the surfaces of natural things invited observation, manipulation, measurement, and re-configuration, with the promise to unveil the knowledge of depths, this article explores how practical knowledge about the surface of things and bodies led to new conceptions of nature and matter as composed of layers, corpuscles, and artificially reproducible solid parts in early modern Europe. This article (...) explores issues of knowledge production, and studies the ways in which material knowledge-making practices contributed to the habits of observing and experimenting with the surface of nature. By discussing three groups of cases in which nature was known by its surface and practice was mixed with theoretical appraisals of matter—surgeons, butchers, and food-cutters; gardeners and agronomists; and physicians—this article argues that “cognitive models” focusing on the description as well as the manipulation of natural surfaces informed both artisanal practices and natural philosophy, bridging the “high” and the “low” in the age of the “scientific revolution.”.
