ABSTRACT The article presents the federalist thought of Carlo Cattaneo, Giuseppe Ferrari and Alberto Mario and Gaetano Salvemini. Referring briefly to the recognised failures of the federal idea in Italy and the corresponding difficulties with its territorial puzzle’ as well, the author proposes to analyse their argumentation through the prism of their attempts to find a proper federal structure for this country. The article shows that despite their eagerness to make Italy perfectly compatible with its ‘natural’ diversity, they (...) gave different answers to the Italian federalist dilemma: whether to begin the whole process with the communes or with more subnational units or rather somewhat include both elements. As will be seen, it was perhaps Salvemini who outlined the most coherent and Cattanean conception that recognised again the necessity of local initiative. Yet, as will be also seen, his federalism, intertwine from the beginning with his concern about the Italian South, was not free from its own weaknesses. (shrink)

The ancient dualism of a sensible and an intelligible world important in Neoplatonic and medieval philosophy, down to Descartes and Kant, would seem to be supplanted today by a scientific view of mind-in-nature. Here, we revive the old dualism in a modified form, and describe mind as a symbolic language, founded in linguistic recursive computation according to the Church-Turing thesis, constituting a world L that serves the human organism as a map of the Universe U. This methodological distinction of L (...) vs. U helps to understand how and why structures of phenomena come to be opposed to their nature in human thought, a central topic in Heideggerian philosophy. U is uncountable according to Georg Cantor’s set theory but Language L, based on the recursive function system, is countable, and anchored in a Gray Area within U of observable phenomena, typically symbols, prelinguistic structures, genetic-historical records of their origins. Symbols, the phenomena most familiar to mathematicians, are capable of being addressed in L-processing. The Gray Area is the human Environment E, where we can live comfortably, that we manipulate to create our niche within hostile U, with L offering overall competence of the species to survive. The human being is seen in the light of his or her linguistic recursively computational mind. Nature U, by contrast, is the unfathomable abyss of being, infinite labyrinth of darkness, impenetrable and hostile to man. The U-man, biological organism, is a stranger in L-man, the mind-controlled rational person, as expounded by Saint Paul. Noumena can now be seen to reside in L, and are not fully supported by phenomena. Kant’s noumenal cause is the mental L-image of only partly phenomenal causation. Mathematics occurs naturally in pre-linguistic phenomena, including natural laws, which give rise to pure mathematical structures in the world of L. Mathematical foundation within philosophy is reversed to where natural mathematics in the Gray Area of pre-linguistic phenomena can be seen to be a prerequisite for intellectual discourse. Lesser, nonverbal versions of L based on images are shared with animals. (shrink)

Recent work in philosophical logic has taken interesting and unexpected turns. It has seen not only a proliferation of logical systems, but new applications of a wide range of different formal theories to philosophical questions. As a result, philosophers have been forced to revisit the nature and foundation of core logical concepts, chief amongst which is the concept of logical consequence. This essay sets the contributions of the volume in context and identifies how they advance important debates within the philosophy (...) of logic. (shrink)

Ian Hacking’s wide-ranging and penetrating analysis of science contains two well-developed lines of thought. The first emphasizes the contingent history of our inquiries into nature, focusing on the various ways in which our concepts and styles of reasoning evolve through time, how their current application is constrained by the conditions under which they arose, and how they might have evolved differently. The second is the mistrust of the idea that the world contains mind-independent natural kinds, preferring nominalism to ‘inherent (...) structurism’. These two pillars of thought seem at first to be mutually reinforcing: the lack of natural structure can help make sense of scientific variability and revision, while variability and revision provide reason to suspect that natural structure is little more than idealization. In what follows, I argue that these two pillars not only fail to support each other, but in fact conflict. One of them must fall, and it is clear which. (shrink)

This text addresses the problems of complex systems in understanding natural phenomena and the behaviour of systems related to human activity, from a science and humanities perspective. It discusses molecular behaviour and structures, and offers examples of ecological and environmental modelling.

Hilary Kornblith presents an account of inductive inference that addresses both its metaphysical and epistemological aspects. He argues that inductive knowledge is possible by virtue of the fit between our innate psychological capacities and the causal structure of the world. Kornblith begins by developing an account of natural kinds that has its origins in John Locke's work on real and nominal essences. In Kornblith's view, a natural kind is a stable cluster of properties that are bound together (...) in nature. The existence of such kinds serves as a natural ground of inductive inference. Kornblith then examines two features of human psychology that explain how knowledge of natural kinds is attained. First, our concepts are structured innately in a way that presupposes the existence of natural kinds. Second, our native inferential tendencies tend to provide us with accurate beliefs about the world when applied to environments that are populated by natural kinds. (shrink)

J. Ladyman, Ladyman and Ross refine J. Worral's structural realism, by developing an ontic structural realism which they argue is a consistently naturalistic means of characterizing the ontology of fundamental physics. I argue that elements of analytic metaphysics strengthen and refine their project of characterizing fundamental physics via OSR and by extension, their presentation of information-theoretic structural realism. I refine this point by situating M. Lange’s discussion of nomological modality qua natural necessity within Ladyman and Ross’s discussion of ITSR. (...) The logical hierarchy evinced in Lange’s ‘nomic stability’ further extends and refines Ladyman and Ross’s claims through the addition of nuanced modal distinctions in a systematic framework.

What is attention? How does attention shape consciousness? In an approach that engages with foundational topics in the philosophy of mind, the theory of action, psychology, and the neurosciences this book provides a unified and comprehensive answer to both questions. Sebastian Watzl shows that attention is a central structural feature of the mind. The first half of the book provides an account of the nature of attention. Attention is prioritizing, it consists in regulating priority structures. Attention is not another element (...) of the mind, but constituted by structures that organize, integrate, and coordinate the parts of our mind. Attention thus integrates the perceptual and intellectual, the cognitive and motivational, and the epistemic and practical. The second half of the book concerns the relationship between attention and consciousness. Watzl argues that attentional structure shapes consciousness into what is central and what is peripheral. The center-periphery structure of consciousness cannot be reduced to the structure of how the world appears to the subject. What it is like for us thus goes beyond the way the world appears to us. On this basis, a new view of consciousness is offered. In each conscious experience we actively take a stance on the world we appear to encounter. It is in this sense that our conscious experience is our subjective perspective. (shrink)

The Nature of Concepts examines a central issue for all the main disciplines in cognitive science: how the human mind creates and passes on to other human minds a concept. An excellent cross-disciplinary collection with contributors including Steven Pinker, Andy Clarke and Henry Plotkin.

Ontic Structural Realism is a version of realism about science according to which by positing the existence of structures, understood as basic components of reality, one can resolve central difficulties faced by standard versions of scientific realism. Structures are invoked to respond to two important challenges: one posed by the pessimist meta-induction and the other by the underdetermination of metaphysics by physics, which arises in non-relativistic quantum mechanics. We argue that difficulties in the proper understanding of what a structure (...) is undermines the realist component of the view. Given the difficulties, either realism should be dropped or additional metaphysical components not fully endorsed by science should be incorporated. (shrink)

The problem of semantic closedness of natural, or colloquial, languages presupposes the investigation of the entire class of their essential semantic properties rather than that of individual instances. To be more concrete, the properties involved are those of universality, antinomisity, and the lack of strict distinction between language and metalanguage. There are reasons to believe that those properties in their totality constitute what underlies the structural unity and functional completeness of natural languages as exceptionally complex informational-communicative systems.

The COVID-19 pandemic has been one of the most acute global crises in recent history, which profoundly impacted the world across many dimensions. During this period, racism manifested in ways specifically related to the pandemic, including xenophobic sentiments, racial attacks, discriminatory policies, and disparate outcomes across racial/ethnic groups. This paper examines some of the pressing questions about pandemic racism and inequity. We review what research has revealed about the nature and manifestations of racism, the entrenchment of structural racism, and trajectories (...) of racism during COVID-19. (shrink)

The aim of this paper is to describe and characterize some structural features of natural reasoning by analyzing a number of conversations held by operators during shift changeovers. During this work phase the operators have to cooperate in order to carry out the same process. This need to cooperate leads to dialogues and joint elaboration of information, especially when involving the reporting of a malfunction. Three dialogues observed at this work phase on two study sites are analyzed. These analyses (...) show that the step by step follow-up of the operators' collective reasoning is feasible. They highlight that these reasonings are complex experimental and hypothetico-deductive reasonings. They are reasonings for action, that are elaborated as the conversation unfolds, and for which the operators do not always have the means of testing their hypotheses. (shrink)

Unlike those with type 1 blindsight, people who have type 2 blindsight have some sort of consciousness of the stimuli in their blind field. What is the nature of that consciousness? Is it visual experience? I address these questions by considering whether we can establish the existence of any structural—necessary—features of visual experience. I argue that it is very difficult to establish the existence of any such features. In particular, I investigate whether it is possible to visually, or more generally (...) perceptually, experience form or movement at a distance from our body, without experiencing colour. The traditional answer, advocated by Aristotle, and some other philosophers, up to and including the present day, is that it is not and hence colour is a structural feature of visual experience. I argue that there is no good reason to think that this is impossible, and provide evidence from four cases—sensory substitution, achomatopsia, phantom contours and amodal completion—in favour of the idea that it is possible. If it is possible then one important reason for rejecting the idea that people with type 2 blindsight do not have visual experiences is undermined. I suggest further experiments that could be done to help settle the matter. (shrink)

It is common in contemporary metaphysics to distinguish two levels of ontology: the ontology of ordinary objects and the ontology of fundamental reality. This papers argues that natural language reflects not only the ontology of ordinary objects, but also a language-driven ontology, which is involved in the mass-count distinction and part-structure-sensitive semantic selection, as well as perhaps the light ontology of pleonastic entities. The paper recasts my older theory of situated part structures without situations, making use of a (...) primitive notion of unity. (shrink)

J. Ladyman, Ladyman and Ross refine J.

I demonstrate this point by situating M. Lange’s discussion of nomological modality and natural necessity within Ladyman and (...) Ross’s discussion of ITSR. The logical hierarchy evinced in Lange’s notion of ‘nomic stability’ further refines Ladyman and Ross’s claims through the addition of nuanced modal distinctions in a systematic framework. Moreover, I argue that what Lange considers are the ‘lawmakers’ serve as a de dicto rendition of some of Ladyman & Ross’s fundamental de re extensions and refinements of ‘real patterns’. (shrink)

We distinguish dynamical and statistical interpretations of evolutionary theory. We argue that only the statistical interpretation preserves the presumed relation between natural selection and drift. On these grounds we claim that the dynamical conception of evolutionary theory as a theory of forces is mistaken. Selection and drift are not forces. Nor do selection and drift explanations appeal to the (sub-population-level) causes of population level change. Instead they explain by appeal to the statistical structure of populations. We briefly discuss (...) the implications of the statistical interpretation of selection for various debates within the philosophy of biologythe `explananda of selection' debate and the `units of selection' debate.

Se divide en tres partes: la primera examina la estructura compleja de las máquinas naturales, a partir de la cual se puede observar una composición dual de la acción; a partir de esto, la segunda parte (...) distingue tres tipos de mónadas con la intención de perfilar la posibilidad de una agencia racional; y, finalmente, la tercera parte ofrece algunas conclusiones relevantes para su teoría de la acción, como el papel de la percepción en el proceso de elección y el intelectualismo leibniziano, entre otros.: This paper aims to analyze key postulates of Leibniz’s vitalist ontology, with a special emphasis on his conception of a natural machine and his monadological proposal. It is divided into three sections: first I analyze the complex structure of natural machines, from which a twofold composition of action can be reckoned; hence, the second section identifies three kinds of monads, with the purpose of devising the possibility of rational agency; finally, the third section draws some relevant conclusions for Leibniz’s account of action, as the place of perception in the process of choice and Leibnizian intellectualism, among others.

Belief in propositions has had a long and distinguished history in analytic philosophy. Three of the founding fathers of analytic philosophy, Gottlob Frege, Bertrand Russell, and G. E. Moore, believed in propositions. Many philosophers since then have shared this belief; and the belief is widely, though certainly not universally, accepted among philosophers today. Among contemporary philosophers who believe in propositions, many, and perhaps even most, take them to be structured entities with individuals, properties, and relations as constituents. For example, the (...) proposition that Glenn loves Tracy has Glenn, the loving relation, and Tracy as constituents. What is it, then, that binds these constituents together and imposes structure on them? And if the proposition that Glenn loves Tracy is distinct from the proposition that Tracy loves Glenn yet both have the same constituents, what is about the way these constituents are structured or bound together that makes them two different propositions? In The Nature and Structure of Content, Jeffrey C. King formulates a detailed account of the metaphysical nature of propositions, and provides fresh answers to the above questions. In addition to explaining what it is that binds together the constituents of structured propositions and imposes structure on them, King deals with some of the standard objections to accounts of propositions: he shows that there is no mystery about what propositions are; that given certain minimal assumptions, it follows that they exist; and that on his approach, we can see how and why propositions manage to have truth conditions and represent the world as being a certain way. The Nature and Structure of Content also contains a detailed account of the nature of tense and modality, and provides a solution to the paradox of analysis. Scholars and students working in the philosophy of mind and language will find this book rewarding reading. (shrink)

This provocative study revives a classical idea about rationality by developing analogies between the structure of personality and the structure of society in the context of contemporary work in the philosophy of mind, ehtics, decision theory, and social choice theory.

Utterances of natural language sentences can be used to communicate not just contents, but also forces. This paper examines this topic from a cross-linguistic perspective on sentential mood. Recent work in this area focuses on conversational dynamics: the three sentence types can be associated with distinctive kinds of conversational effects called sentential forces, modeled as three kinds of updates to the discourse context. This paper has two main goals. First, it provides two arguments, on empirical and methodological grounds, for (...) treating sentential force as part of a compositional dynamic semantics, rather than a dynamic pragmatics. Second, it formulates a minimal dynamic semantic analysis that covers the data at the heart of these arguments, incorporating existing analyses of the three major moods, evidentials and conjunction. A further aim of the paper is to sharpen the distinction between sentential force and utterance force, and discuss its implications. (shrink)

Hurley here revives a classical idea about rationality in a modern framework, by developing analogies between the structure of personality and the structure of society in the context of contemporary work in philosophy of mind, ethics, decision theory and social choice theory. The book examines the rationality of decisions and actions, and illustrates the continuity of philosophy of mind on the one hand, and ethics and jurisprudence on the other. A major thesis of the book is that arguments (...) drawn from the philosophy of mind may be used to undermine widely-held subjectivist positions in ethics and politico-economic theory. The work is inspired by the philosophies of Wittgenstein and Davidson, but goes on to connect their arguments about interpretation with formal work in decision theory and social choice theory, and with the theory of adjudication.

The representation and classification of the structure of natural arguments has been one of the most important aspects of Aristotelian and medieval dialectical and rhetorical theories. This traditional approach is represented nowadays in models of argumentation schemes. The purpose of this article is to show how arguments are characterized by a complex combination of two levels of abstraction, namely, semantic relations and types of reasoning, and to provide an effective and comprehensive classification system for this matrix of semantic (...) and quasilogical connections. To this purpose, we propose a dichotomous criterion of classification, transcending both levels of abstraction and representing not what an argument is but how it is understood and interpreted. The schemes are grouped according to an end-means criterion, which is strictly bound to the ontological structure of the conclusion and the premises. On this view, a scheme can be selected according to the intended or reconstructed purpose of an argument and the possible strategies that can be used to achieve it. (shrink)

This book presents a new theory of the relationship between vagueness, context-sensitivity, gradability, and scale structure in natural language. Heather Burnett argues that it is possible to distinguish between particular subclasses of adjectival predicatesDLrelative adjectives like tall, total adjectives like dry, partial adjectives like wet, and non-scalar adjectives like hexagonalDLon the basis of how their criteria of application vary depending on the context; how they display the characteristic properties of vague language; and what the properties of their associated (...) orders are. It has been known for a long time that there exist empirical connections between context-sensitivity, vagueness, and scale structure; however, a formal system that expresses these connections had yet to be developed. This volume sets out a new logical system, called DelTCS, that brings together insights from the Delineation Semantics framework and from the Tolerant, Classical, Strict non-classical framework, to arrive at a full theory of gradability and scale structure in the adjectival domain. The analysis is further extended to examine vagueness and gradability associated with particular classes of determiner phrases, showing that the correspondences that exist between the major adjectival scale structure classes and subclasses of determiner phrases can also be captured within the DelTCS system.

Hegel’s Philosophy of Right responds to two dichotomies. One is between the freedom of rational thought in its practical application and the givenness of natural impulses and desires. Against Kant Hegel argues that pure reason alone cannot determine the content of any maxim or principle of action. Thus Hegel must find a way in which the content of natural needs and impulses – the only source of content for maxims of action – can be transfigured into contents of (...) rationally self-given principles and maxims. Hegel also responds to the dichotomy between the individual agent and the social whole within which agents act. Hegel argues that this dichotomy is specious because human beings are fundamentally social practitioners and because neither social practices nor individual agents have priority over the other. There are no social practices without social practitioners and there are no social practitioners without social practices. Hegel’s response to this second dichotomy allows him to respond to the first one as well. The elaboration and specialization of natural needs and desires through exchange relations and the social division of labor transfigures the contents of those needs and desires into collectively self-given ends. The social practices producing this transfiguration and meeting these ends form the contents of implicit principles of right. These implicit principles are collectively self-given because they result from the social practices collectively developed to meet these needs. Only acts that are executed and accepted by an agent are free acts. This strong condition requires that an agent’s intentions correspond to the actual nature and consequences of his or her act. Since the aims, the principles, and the means of action are fundamentally social, these strong constraints entail that free action is possible only within a community which makes known its structure and the role of its members within it and their contribution to it, so that its members can act on the basis of that knowledge. Hegel’s theory of the state is a theory of a communal structure that makes such explicit, free action possible. In briefest compass, Hegel holds that laws are legitimate only insofar as they codify those practices that have been developed in order to achieve human freedom, and laws are obligatory only insofar as they are necessary for achieving human freedom. Hegel’s government is designed to codify and promulgate such laws. Hegel’s legislature is designed to make known to the citizens at large, through their corporate representatives, that laws have such a basis and how individual roles and actions fit within the community as a whole.

Aristotle’s account of natural slavery as presented in his Politics is often treated by historians of philosophy as an account that can be analyzed purely internally in terms of its argumentative structure without referring to social factors. Against this view, Aristotle’s account of natural slavery is seen to be ideological according to at least one variant of the Marxist concept of ideology, and cannot be understood without reference to Aristotle’s socioeconomic context. The ideological nature of Aristotle’s account (...) of natural slavery is especially evident in his “proto-racialization” of the category of the “natural slave.” The Marxist concept of ideology is demonstrably useful in the historical study of philosophy, as compared with internalist historians of philosophy who claim that referring to nonphilosophical factors such as class interests inevitably obscures the philosophical content of the texts that are the objects of analysis.

Natural deduction with alternatives extends Gentzen–Prawitz-style natural deduction with a single structural addition: negatively signed assumptions, called alternatives. It is a mildly bilateralist, single-conclusion natural deduction proof system in which the connective rules are unmodi_ed from the usual Prawitz introduction and elimination rules — the extension is purely structural. This framework is general: it can be used for (1) classical logic, (2) relevant logic without distribution, (3) affine logic, and (4) linear logic, keeping the connective rules fixed, (...) and varying purely structural rules. The key result of this paper is that the two principles that introduce kinds of irrelevance to natural deduction proofs: (a) the rule of explosion (from a contradiction, anything follows); and (b) the structural rule of vacuous discharge; are shown to be two sides of a single coin, in the same way that they correspond to the structural rule of weakening in the sequent calculus. The paper also includes a discussion of assumption classes, and how they can play a role in treating additive connectives in substructural natural deduction. (shrink)

Philosophers have almost always said something about emotions and passions whenever they have discussed human mental life. Many have asserted that it is some emotions or, more broadly, passions, that are to be primarily valued and sought. These valued passionate states of mind might include emotions, moods, desires, belief-like feelings of conviction and commitment, and romantic or erotic love, which are typically scarcely distinguished. Not only are these states of mind lumped together, but the reasons why they are valued may (...) likewise be various: they may be valued because of their intrinsic feeling (especially insofar as they are intense), through their long-term or deep effects on the rest of our practical and mental lives, through their effects on others’ lives, or even in the glimpse they give us of an object that transcends our mundane and superficial concerns, as in love, peak experiences, or intimations of God, Beauty, or Nature. Others have claimed that it is in the subduing or elimination of some or all of these passions that the ideal human life consists. Again, what precisely are the objectionable passions is typically not delineated, and why such mental states are objectionable may be diverse and even unspecified. One might resent their "disruptive" nature on our mental life, especially insofar as some of them stem from external, uncontrollable sources, and instead seek a calm state that is within one’s control and not subject to these whimsical externalities. Or one can see many or all passions as disruptive of control and success in our inner or outer life, or in the lives of others. We might call this latter group the anti-emotional Rationalists, and the former group the pro-emotional Romantics. (shrink)

Inductive reasoning is fundamental to human cognition, yet it remains unclear how we develop this ability and what might influence our inductive choices. We created novel categories in which crucial factors such as domain and category structure were manipulated orthogonally. We trained 403 4–9-year-old children to categorise well-matched natural kind and artefact stimuli with either featural or relational category structure, followed by induction tasks. This wide age range allowed for the first full exploration of the developmental trajectory (...) of inductive reasoning in both domains. We found a gradual transition from perceptual to categorical induction with age. This pattern was stable across domains, but interestingly, children showed a category bias one year later for relational categories. We hypothesise that the ability to use category information in inductive reasoning develops gradually, but is delayed when children need to process and apply more complex category structures.

The fine structure constant appears in several fields of physics and its value is experimentally obtained with a high accuracy. Its physical origin however is unsolved long-standing problem. Richard Feynman expressed the idea that it could be similar to the natural irrational numbers, pi, and e. Amongst the proposed theoretical expressions with values closer to the experimental one is the formula of I. Gorelik which is based on rotating dipole with two empirically suggested coefficients, while the physical origin (...) is unknown. BSM-Supergravitation Unified Theory suggests a physical mechanism defining the fine structure constant. The mathematical expression is based on a spatial precession mode of vibrations in a tetrahedron of spheres with specific properties. The value from the derived expression differs from the CODATA 98 value by 0.000008% only. The conclusion is that the fine structure constant is a natural irrational number. While the irrational number pi, is defined in a 2D space, the fine structure constant is related to a vibration property of a specific formation in 3D space. (shrink)

We describe a knowledge representation and inference formalism, based on an intensional propositional semantic network, in which variables are structures terms consisting of quantifier, type, and other information. This has three important consequences for natural language processing. First, this leads to an extended, more natural formalism whose use and representations are consistent with the use of variables in natural language in two ways: the structure of representations mirrors the structure of the language and allows re-use (...) phenomena such as pronouns and ellipsis. Second, the formalism allows the specification of description subsumption as a partial ordering on related concepts (variable nodes in a semantic network) that relates more general concepts to more specific instances of that concept, as is done in language. Finally, this structured variable representation simplifies the resolution of some representational difficulties with certain classes of natural language sentences, namely, donkey sentences and sentences involving branching quantifiers. The implementation of this formalism is called ANALOG (A NAtural LOGIC) and its utility for natural language processing tasks is illustrated. (shrink)

Biological organisms appear to have agency, goals, and meaningful behaviour. One possibility is that this is mere appearance, where such properties are not real, but only ‘as if’ consequences of the physiological structure of organisms. Another possibility is that these properties are real, as emerging from the organism's structure and from how the organism interacts with its environment. Here I will discuss a recent theory showing that the latter position is most likely correct, and argue that the theory (...) is largely consistent with the basics of the field of biosemiotics. The theory can be represented as a triad that resembles the semiotic triad proposed by Peirce, which connects a sign with its object through a process of interpretation. In the theory presented, the sign is an internalized version of fitness which refers to the true fitness through a feedback loop that in effect produces interpretation. The feedback loop entangles deterministic and stochastic forms of causation in such a way that genuine agency, goal-directedness, and their associated meaning emerge. It produces a strong form of emergence not reducible to its constituents. The result is that novel phenomena arise that are real and necessary components for a complete understanding of living organisms. (shrink)

Several recent interpretations see Hegel's theory of the Concept as a form of conceptual realism, according to which finite reality is articulated by objectively existing concepts. More precisely, this theory has been interpreted as a version of natural kind essentialism, and it has been proposed that its function is to account for the possibility of genuine explanations. This suggests a promising way to reconstruct the argument that Hegel's theory of objective concepts is based on—an argument that shows that the (...) possibility of explanation rests on metaphysical preconditions and that natural kind essentialism gives the only adequate account of those preconditions. But in order for such a reconstruction to be successful, one needs to spell out the metaphysical features in virtue of which Hegelian natural kinds can account for the possibility of explanation. The article takes up this challenge. It offers the first detailed analysis of the modal fine-structure of Hegel's natural kind essentialism and shows how Hegel's position, thus understood, provides the details needed to complete the explanation-based argument.

In the first full-length study in any modern language dedicated to the Meteorologica, Malcolm Wilson presents a groundbreaking interpretation of Aristotle's natural philosophy. Divided into two parts, the book first addresses general philosophical and scientific issues by placing the treatise in a diachronic frame comprising Aristotle's predecessors and in a synchronic frame comprising his other physical works. It argues that Aristotle thought of meteorological phenomena as intermediary or 'dualizing' between the cosmos as a whole and the manifold world of (...) terrestrial animals. Engaging with the best current literature on Aristotle's theories of science and metaphysics, Wilson focuses on issues of aetiology, teleology and the structure and unity of science. The second half of the book illustrates Aristotle's principal concerns in a section-by-section treatment of the meteorological phenomena and provides solutions to many of the problems that have been raised since the time of the ancient commentators.

In the framework of set theory we cannot distinguish between natural and non-natural predicates. To avoid this shortcoming one can use mathematical structures as conceptual spaces such that natural predicates are characterized as structurally nice subsets. In this paper topological and related structures are used for this purpose. We shall discuss several examples taken from conceptual spaces of quantum mechanics (orthoframes), and the geometric logic of refutative and affirmable assertions. In particular we deal with the problem of (...) structurally distinguishing between natural colour predicates and Goodmanian predicates like grue and bleen. Moreover the problem of characterizing natural predicates is reformulated in such a way that its connection with the classical problem of geometric conventionalism becomes manifest. This can be used to shed some new light on Goodman's remarks on the relative entrenchment of predicates as a criterion of projectibility. (shrink)

This chapter examines whether, and in what sense, one can speak of agentive mental events. An adequate characterization of mental acts should respond to three main worries. First, mental acts cannot have pre-specified goal contents. For example, one cannot prespecify the content of a judgment or of a deliberation. Second, mental acts seem to depend crucially on receptive attitudes. Third, it does not seem that intentions play any role in mental actions. Given these three constraints, mental and bodily actions appear (...) to have a significantly different structure. A careful analysis of the role of normative requirements, distinguishing them from instrumental reasons, allows the distinction between mental and bodily forms of action to be clarified. Two kinds of motives must be present for a mental act to develop. The first kind is instrumental: a mental act is performed because of some basic informational need, such as the need to "remember the name of that play". The second kind is normative: given the specific type of mental action performed, there is a specific epistemic norm relevant to that act. These two motives actually correspond to different phases of a single mental act. The first motivates the mental act, i.e. makes salient the corresponding goal. The second offers an evaluation of the feasibility of the act, on the basis of its constitutive normative requirement. Conceived in this way, a characterization of mental acts avoids the three difficulties mentioned above. The possibility of pre-specifying the outcome of epistemic mental acts is blocked by the fact that such acts are constituted by strict normative requirements. That mental acts include receptive features is shown to be a necessary architectural constraint for mental agents to be sensitive to epistemic requirements. Finally, the phenomenology of intending is shown to be absent in most mental acts; the motivational structure of mental acts is, rather, associated with error- signals and self-directed doubtings. Mental acts need to be recognized as a natural kind of action meant to normatively control and enhance cognitive efficiency according to current processing needs. (shrink)

In philosophy of science two questions become central in the discussion of the nature of empirical science: 1) What is a theory, i.e. how is it built up, how does it work? And: 2) How does a theory relate to its corresponding experiential basis? To deal with these two questions modern philosophy of science has devised various ‘models’ on the nature and working of scientific theories. Some aspects of these models are widely held within the community of philosophers of science, (...) but others are still being discussed quite controversially. In this paper, we will consider both kinds of aspects. Particularly, we will analyze how the meaning of scientific concepts is determined; the axiomatic construction of a scientific theory; the idea of model building views as a bridge between theory and experience; the holistic semantic thesis of science; the question about the true of scientific theories; and, finally, the hierarchic structure of theories.En filosofía de la ciencia, dos cuestiones resultan centrales en la discusión acerca de la naturalezade la ciencia empírica: 1) ¿qué es una teoría ?, es decir, ¿cómo estáconstituida y cómo funciona? y 2) ¿cómo se relaciona una teoría con su correspondientebase experiencial? Para tratar estas dos cuestiones, la moderna filosofía de la ciencia ha desarrolladovarios “modelos” sobre la naturaleza y el funcionamiento de lasteorías científicas. Algunos aspectos de estos modelos son ampliamente aceptados por lacomunidad de filósofos de la ciencia, mientras que otros son todavía discutidos de manerabastante controvertida. En este trabajo, consideraremos ambos tipos de aspectos. En particular,analizaremos cómo se determina el significado de los conceptos teóricos, la construcción axiomática de una teoría científica, la idea de las concepciones sobre la construcción de modelos como puente entre la teoría y la experiencia, la tesis semántica holista de la ciencia, la cuestión acerca de la verdad de las teorías científicas y, finalmente, la estructura jerárquica de las teorías.

The initial premise of this paper is that the structure of a proof is inherent in the definition of the proof. Side conditions to deal with the discharging of assumptions means that this does not hold for systems of natural deduction, where proofs are given by monotone inductive definitions. We discuss the idea of using higher order definitions and the notion of a functional closure as a foundation to avoid these problems. In order to focus on structural issues (...) we introduce a more abstract perspective, where a structural proof theory becomes part of a more general theory of functional closures. A notion of proof equations is discussed as a structural classifier and we compare the Russell and Ekman paradoxes to illustrate this. (shrink)

What I have tried to do here is to provide a historical example of the interdependence between nature and culture that is one of the themes of this conference. To sum up: Scientific descriptions of the world emerge out of a complex interaction between nature, economic production, and the legal system. “Science” consists of a struggle among scientists, and between scientists and citizens, over what counts as “reality.” Lawmaking, in turn, consists of a struggle between people who want to allocate (...) access to resources for particular purposes, whether for commercial use, recreational use, or “natural” uses. Production, for its part, is a complicated function of technology, the sociology of user groups, the structure of legal entitlements to access, and the availability of resources. Nature, finally, is at any point, to no small degree, the product of past and present human impacts on it — which impacts, in turn, are determined in no small way by the sociology and the legal structure of the market.Each process takes place in continual conversation with all the others. As John Muir put it, “When we try to pick out anything by itself, we find it hitched to everything else in the universe.”45 Historically, resource managers have gotten into trouble when they have unconsciously assumed that such is not the case — yet such, assumptions are powerful because they are made instinctively, unthinkingly, at the level of people's basic understanding of the world and their place in it. Lots of them persist.On the other hand, in a few experimental cases in the United States and Canada where government and users have shared power and responsibility for resources management, including long-range planning for recovery and enhancement, here have been some notable improvements. The strategy goes under the name of “co-management” and involves negotiated agreements for shared decision-making between central authority and local groups. Typically, both government and industry resist such arrangements because they involve restructuring the power relations between different sectors in the industry; the result is that the few experiments in co-management that we have seen in the United States have come in areas, typically fisheries and wildlife, where the resource is in serious crisis and all of the parties to the agreement have had to abandon the positions they held previously.Examples of successful co-management regimes include those among American tribes in the Pacific Northwest, among commercial salmon fishers in Alaska, and in a project to rehabilitate the clam industry in New Jersey. Government employees and local groups share responsibility for gathering scientific data about the resources, for developing plans to manage them, and for enforcing regulations. Successful experiments at co-management seem to generate better scientific data about their resources than traditional management regimes do; they significantly reduce enforcement costs; and they enhance the economic power of the resource users. Most importantly, they nurture among the user groups a sense of control over their own destinies, and a willingness to share both costs and benefits of managing the resources rationally and to develop lasting, stable mechanisms for conflict resolution. The process is both democratic and ecologically rational. The key is to link the day-to-day work of producers to their long-range interests as residents in their communities and as working parts of the ecological systems in which they live.45At a minimum, it is clear that objective certainty about the state of the resources or the likely effect of whatever regulations we do impose is simply not attainable. This is partly because of the important role that random shocks play in the environment (and should play in our thinking about it), and also because of the sheer complexity of the system in which we are embedded. There will always be something that even the most complete model leaves out; and in any event the total system of ecology, production, and management will change every time something changes in any part of it.The policy lesson to be derived from all of this, finally, is that what we ought to sustain when we approach conservation problems is not the size of a particular resource, or even the prosperity of a particular harvesting group, but the long-term health of the interaction between nature, the economy, and the political system. We can recognize that the balance of the system, our attempted insurance against an uncertain future, democracy among user groups, and our moral duty to avoid extinguishing species — all of these things being difficult to quantify — do play integral roles in the conversation between nature and humankind, and perhaps more significant roles than the more objective measures to which we usually look for guidance. We can recognize, as John Muir did, that because everything in the universe is hitched to everything else, every step we take will change the total system in some way. When we make choices, then, we can keep an eye on what kind of conversation we want to have with the rest of Creation and make our choices accordingly. *** DIRECT SUPPORT *** A8402064 00014 *** DIRECT SUPPORT *** A8402064 00015.

The paper defends two claims; Viewed from the perspective of the substantivalism/relationism debate, structural spacetime realism is a form of relationism; However, if we managed to reinforce Rynasiewicz’s point that the general theory of relativity makes the substantivalism/relationism dispute “outdated”, the re-elaboration of Stein ’s 1967 version of structural spacetime realism to be proposed here proves to be a good, antimetaphysical solution to the problem of the ontological status of spacetime.
