To determine whether fish welfare matters morally, we need to know what characteristics or capacities beings need to have in order to be morally considerable, and whether fish have such characteristics. In this paper I discuss a group of theories, Kantian practical reasoning theories, in which agency (or practical rationality) is traditionally thought to be a necessary condition for moral considerability. An individual must have quite sophisticated capacities to be a (moral) agent in such theories: she must be able to (...) act on rational principles. It seems unlikely that nonhuman animals such as fish have such capacities. I argue, however, that on the basis of certain Kantian arguments, moral agents have reason to accept duties to nonrational animals if they are agents in a much less demanding sense: if they are motivated to pursue the objects of their desires. If fish have this capacity, their welfare matters morally. (shrink)

Artifacts are probably our most obvious everyday encounter with technology. Therefore, a good understanding of the nature of technical artifacts is a relevant part of technological literacy. In this article we draw from the philosophy of technology to develop a conceptualization of technical artifacts that can be used for educational purposes. Furthermore we report a small exploratory empirical study to see to what extent teachers’ intuitive ideas about artifacts match with the way philosophers write about the nature of artifacts. Finally, (...) we suggest a teaching and learning strategy for improving teachers’ concepts of technical artifacts through practical activities. (shrink)

This article establishes the existence of a definable , countably saturated nonstandard enlargement of the superstructure over the reals. This nonstandard universe is obtained as the union of an inductive chain of bounded ultrapowers . The underlying ultrafilter is the one constructed by Kanovei and Shelah [10].

The paper gives a detailed reconstruction and discussion of Peirce’s doctrine of propositions, so-called Dicisigns, developed in the years around 1900. The special features different from the logical mainstream are highlighted: the functional definition not dependent upon conscious stances nor human language, the semiotic characterization extending propositions and quasi-propositions to cover prelinguistic and prehuman occurrences of signs, the relations of Dicisigns to the conception of facts, of diagrammatical reasoning, of icons and indices, of meanings, of objects, of syntax in Peirce’s (...) logic-as-semiotics.

Lucretius famously argued that if we think death is bad because it deprives us of time we could have had by living longer than we do, then when we are born must be bad too, since we could have been born earlier than we were, and so be deprived of that time as well. John Martin Fischer thinks Lucretius’s symmetry argument fails because we have a bias toward the future. I argue that Fischer’s approach does not answer Lucretius. In contrast (...) to Fischer, I think that we can show an objective difference between the time before our birth and the time after our death, which means that we are justified in adopting different attitudes towards them. I revise a point made by Thomas Nagel that while we might live longer than we do, we cannot exist earlier than we did and remain the same people throughout. (shrink)

This article is an investigation of parallel themes in Heinrich Hertz's philosophy science and Kant's theory of schemata, symbols and regulative ideas. It is argued that Hertz's "pictures" bears close similarities to Kantian "schemata", that is, they are rules linking concepts to intuitions and provide them with their meaning. Kant's distinction between symbols and schemata is discussed and related to Hertz's three pictures of mechanics. It is argued that Hertz considered his own picture of mechanics as symbolic in a different (...) way than the force and energy pictures. In the final part of the article it is described how Harald Høffding soon after the publication of Hertz's Principles of Mechanics developed a general theory of analogical reasoning, relying on the ideas of Hertz and Kant.

In a recent paper, Jeanne Peijnenburg and David Atkinson [ Studia Logica, 89:333-341 ] have challenged the foundationalist rejection of infinitism by giving an example of an infinite, yet explicitly solvable regress of probabilistic justification. So far, however, there has been no criterion for the consistency of infinite probabilistic regresses, and in particular, foundationalists might still question the consistency of the solvable regress proposed by Peijnenburg and Atkinson.

We characterise the intermediate logics which admit a cut-free hypersequent calculus of the form \, where \ is the hypersequent counterpart of the sequent calculus \ for propositional intuitionistic logic, and \ is a set of so-called structural hypersequent rules, i.e., rules not involving any logical connectives. The characterisation of this class of intermediate logics is presented both in terms of the algebraic and the relational semantics for intermediate logics. We discuss various—positive as well as negative—consequences of this characterisation.

Is there a morally relevant difference between a brain‐damaged human being and a nonhuman animal at the same cognitive and emotional level to justify, say, performing medical experiments on the animal but not the human being? Some hold that the misfortune of the human being allows us to distinguish between them. I consider the nature of misfortunate and argue that an appeal to misfortune fails to distinguish between the human being and the nonhuman animal when the treatment at issue is (...) equally morally serious, since the source of the limitation taken advantage of by performing the medical experiment, whether misfortunate or natural vulnerability, is irrelevant.

Łoś's theorem for bounded D -ultrapowers, D being the ultrafilter introduced by Kanovei and Shelah [4], is established.

Following Lauwers and Van Liedekerke (1995), this paper explores in a model-theoretic framework the relation between Arrovian aggregation rules and ultraproducts, in order to investigate a source of impossibility results for the case of an infinite number of individuals and an aggregation rule based on a free ultrafilter of decisive coalitions.

This note employs the recently established consistency theorem for infinite regresses of probabilistic justification (Herzberg in Stud Log 94(3):331–345, 2010) to address some of the better-known objections to epistemological infinitism. In addition, another proof for that consistency theorem is given; the new derivation no longer employs nonstandard analysis, but utilises the Daniell–Kolmogorov theorem.

The problem of how to rationally aggregate probability measures occurs in particular when a group of agents, each holding probabilistic beliefs, needs to rationalise a collective decision on the basis of a single ‘aggregate belief system’ and when an individual whose belief system is compatible with several probability measures wishes to evaluate her options on the basis of a single aggregate prior via classical expected utility theory. We investigate this problem by first recalling some negative results from preference and judgment (...) aggregation theory which show that the aggregate of several probability measures should not be conceived as the probability measure induced by the aggregate of the corresponding expected utility preferences. We describe how McConway’s :410–414, 1981) theory of probabilistic opinion pooling can be generalised to cover the case of the aggregation of infinite profiles of finitely additive probability measures, too; we prove the existence of aggregation functionals satisfying responsiveness axioms à la McConway plus additional desiderata even for infinite electorates. On the basis of the theory of propositional-attitude aggregation, we argue that this is the most natural aggregation theory for probability measures. Our aggregation functionals for the case of infinite electorates are neither oligarchic nor integral-based and satisfy a weak anonymity condition. The delicate set-theoretic status of integral-based aggregation functionals for infinite electorates is discussed. (shrink)

SUMMARYThe history of the law of nations is generally seen as a synonym for the history of the laws of war. Yet, a strictly bilateral perspective can distort our interpretation of early modern diplomacy. The Peace of Utrecht inaugurated an era of relative stability in the European state system, based on balance-of-power politics and anti-hegemonic legal argumentation. Incidental conflicts ought to be interpreted against this background. Declarations of war issued in 1718, 1719 and 1733 during the War of the Quadruple (...) Alliance and the Polish Succession should not be read as doctrinal surrogates for trials between two parties, but as manifestos in a European arena. (shrink)

The rejection of an infinitesimal solution to the zero-fit problem by A. Elga ([2004]) does not seem to appreciate the opportunities provided by the use of internal finitely-additive probability measures. Indeed, internal laws of probability can be used to find a satisfactory infinitesimal answer to many zero-fit problems, not only to the one suggested by Elga, but also to the Markov chain (that is, discrete and memory-less) models of reality. Moreover, the generalization of likelihoods that Elga has in mind is (...) not as hopeless as it appears to be in his article. In fact, for many practically important examples, through the use of likelihoods one can succeed in circumventing the zero-fit problem. 1 The Zero-fit Problem on Infinite State Spaces 2 Elga's Critique of the Infinitesimal Approach to the Zero-fit Problem 3 Two Examples for Infinitesimal Solutions to the Zero-fit Problem 4 Mathematical Modelling in Nonstandard Universes? 5 Are Nonstandard Models Unnatural? 6 Likelihoods and Densities A Internal Probability Measures and the Loeb Measure Construction B The (Countable) Coin Tossing Sequence Revisited C Solution to the Zero-fit Problem for a Finite-state Model without Memory D An Additional Note on ‘Integrating over Densities’ E Well-defined Continuous Versions of Density Functions.

Two different concepts of iconicity compete in Peirce's diagrammatical logic. One is articulated in his general reflections on the role of diagrams in thought, in what could be termed his diagrammatology — the other is articulated in his construction of Existential Graphs as an iconic system for representing logic. One is operational and defines iconicity in terms of which information may be derived from a given diagram or diagram system — the other has stronger demands on iconicity, adding to the (...) operational criterion a demand for as high a degree of similarity as possible and may be termed optimal iconicity. Peirce himself does not clearly distinguish these two iconicity notions, a fact that has caused some confusion. By isolating them, we get a clearer and more refined conceptual apparatus for analyzing iconic signs, from pictures to logic. (shrink)

On the basis of the Suppes–Sneed structuralview of scientific theories, we take a freshlook at the concept of refutability,which was famously proposed by K.R. Popper in 1934 as a criterion for the demarcation of scientific theories from non-scientific ones, e.g., pseudo-scientificand metaphysical theories. By way of an introduction we argue that a clash between Popper and his critics on whether scientific theories are, in fact, refutablecan be partly explained by the fact Popper and his criticsascribed different meanings to the term (...) theoryThen we narrow our attention to one particular theory,namely quantum mechanics, in order to elucidate general matters discussed. We prove that quantum mechanics is irrefutable in a rather straightforward sense, but argue that it is refutable in a more sophisticated sense, which incorporates someobservations obtained by looking closely at the practiceof physics. We shall locate exactly where non-rigourous elements enter the evaluation of a scientific theory – thismakes us see clearly how fruitful mathematics isfor the philosophy of science. (shrink)

This article sets out to research and resolve the conceptual lag between the family as defined and recognised in law and the multiplicity of queer constellations of ‘intimate citizenship’ in which families are actually done. The focus is on adult unions outside of conjugal coupledom. The family law practices, and awareness and expectations of adults in such unions were analysed through 21 interviews and the content analysis of 40 documents and were projected against the applicable legal mould. The article then (...) proposes to resolve the existing conceptual lag by advancing a conception of the family as a malleable, open-ended assemblage, in lieu of the current rigid status approach in family law, which is both under- and overinclusive. The proposed conception does justice to the increasing fluidity of family formations, which are not always already domestic, dyadic and sexual. (shrink)

This paper formally explores the common ground between mild versions of epistemological coherentism and infinitism; it proposes—and argues for—a hybrid, coherentist–infinitist account of epistemic justification. First, the epistemological regress argument and its relation to the classical taxonomy regarding epistemic justification—of foundationalism, infinitism and coherentism—is reviewed. We then recall recent results proving that an influential argument against infinite regresses of justification, which alleges their incoherence on account of probabilistic inconsistency, cannot be maintained. Furthermore, we prove that the Principle of Inferential Justification (...) has rather unwelcome consequences—formally resembling the Sorites paradox—as soon as it is iterated and combined with a natural Bayesian perspective on probabilistic inferences. We conclude that strong versions of foundationalism and infinitism should be abandoned. Positively, we provide a rough sketch for a graded formal coherence notion, according to which infinite regresses of epistemic justification will often have more than a minimal degree of coherence.

We study a logic for deontic necessity and sufficiency, as originally proposed in van Benthem :36–41, 1979). Building on earlier work in modal logic, we provide a sound and complete axiomatization for it, consider some standard extensions, and study other important properties. After that, we compare this logic to the logic of “obligation as weakest permission” from Anglberger et al. :807–827, 2015).

Summary Whereas many aspects of the Augustan age continue to enjoy ongoing or renewed interest, the early careers of Tiberius Claudius Nero and Nero Claudius Drusus, Livia’s sons from her marriage to Ti. Claudius Nero, have not been subject to much discussion or controversy of late. On the one hand, this could, perhaps, be explained in that they were quite young during the formative stages of the so-called Augustan monarchy, the critical settlements being those of 27, 23 and 19 BCE, (...) the eye-catchers par excellence in the political history of the early Augustan era. On the other hand, Livia’s sons only really emerge into the spotlight of both ancient sources and modern scholarship after the untimely passing of M. Vipsanius Agrippa in 12 BCE. This paper aims at revisiting the evidence for Tiberius’ and Drusus’ careers in the decade or so before the latter’s premature death in Germany in 9 BCE, the period preceding the rapid rise of Gaius and Lucius Caesar. There are, indeed, strong indications that Livia’s sons played a far more important part than has hitherto been recognized, both in terms of their official position and their role in assisting Augustus with one of his most important political objectives, namely the imperial monopolization of the public triumph.

The defence of The No Alternatives Argument in a recent paper by R. Dawid, S. Hartmann and J. Sprenger rests on the assumption that the number of acceptable alternatives to a scientific hypothesis is independent of the complexity of the scientific problem. This note proves a generalisation of the main theorem by Dawid, Hartmann and Sprenger, where this independence assumption is no longer necessary. Some of the other assumptions are also discussed, and the limitations of the no-alternatives argument are explored.

Environmental philosophers are often concerned to show that non-sentient things, such as plants or ecosystems, have interests and therefore are appropriate objects of moral concern. They deny that mentality is a necessary condition for having interests. Yet they also deny that they are committed to recognizing interests in things like machines. I argue that either machines have interests (and hence moral standing) too or mentality is a necessary condition for inclusion within the purview of morality. I go on to argue (...) that the aspect of mentality necessary for having interests is more complicated than mere sentience. (shrink)

Based on the conception of life and semiosis as co-extensive an attempt is given to classify cognitive and communicative potentials of species according to the plasticity and articulatory sophistication they exhibit. A clear distinction is drawn between semiosis and perception, where perception is seen as a high-level activity, an integrated product of a multitude of semiotic interactions inside or between bodies. Previous attempts at finding progressive trends in evolution that might justify a scaling of species from primitive to advanced levels (...) have not met with much success, but when evolution is considered in the light of semiosis such a scaling immediately catches the eye. The main purpose of this paper is to suggest a scaling of this progression in semiotic freedom into a series of distinct steps. The elleven steps suggested are: 1) molecular recognition, 2) prokaryote-eukaryote transformation, 3) division of labor in multicellular organisms, 4) from irritability to phenotypic plasticity, 5) sense perception, 6) behavioral choice, 7) active information gathering, 8) collaboration, deception, 9) learning and social intelligence, 10) sentience, 11) consciousness. In light of this, the paper finally discusses the conceptual framework for biosemiotic evolution. The evolution of biosemiotic capabilities does not take the form of an ongoing composition of simple signs into composite wholes. Rather, it takes the shape of the increasing subdivision and control of a primitive, holophrastic perception-action circuit already committed to “proto-propositions” reliably guiding action already in the most primitive species.

The following two review papers have a common origin. Pietarinen’s book Signs of Logic and Stjernfelt’s book Diagrammatology were both published in the same Synthese Library Series being published by Springer. The two books also share the common topic of diagrammatic reasoning in Charles Peirce’s work. Beginning in a conference Applying Peirce held in Helsinki in conjunction with the World Congress of Semiotics in June 2007, two authors have commented upon these books under the headline of Synthese Library Book Session (...) on several occasions, including the Aarhus meeting on Signs and Meaning held in February 2008, the Diagrammatology and Diagram Praxis workshop in Lisboa in March 2009, and the Peirce and Early Analytic Philosophy symposium in Helsinki in June 2009. Therefore, these two review papers form a continuing discussion on the contributions Peirce’s diagrammatic epistemology and logic will have to a broad range of issues at the intersections of philosophy, logic, cognitive sciences and beyond.

This paper gives a fIrst overview over the role of mereology the theory of parts and wholes - in semiotics. The mereology of four major semioticians - Husserl, Jakobson, Hjelmslev, and Peirce is presented briefly and its role in the overall architecture of each of their theories is outlined - with Brentano tradition as reference. Finally, an evaluation of the strength and weaknesses of the four is undertaken, and some guidelines for further research is proposed.

This article discusses how to deal with the relations between different cultural perspectives in classrooms, based on a proposal for considering understanding and knowledge as goals of science education, inspired by Dewey’s naturalistic humanism. It thus combines educational and philosophical interests. In educational terms, our concerns relate to how science teachers position themselves in multicultural classrooms. In philosophical terms, we are interested in discussing the relations between belief, understanding, and knowledge under the light of Dewey’s philosophy. We present a synthesis (...) of Dewey’s theory of inquiry through his naturalistic humanism and discuss its implications for the concepts of belief, understanding, and knowledge, as well as for the goals of science teaching. In particular, we highlight problems arising in the context of possible conflicts between scientific and religious claims in the school environment that result from totalitarian positions. We characterize an individual’s position as totalitarian if he or she takes some way of thinking as the only one capable of expressing the truth about all that exists in the world, lacks open-mindedness to understand different interpretative perspectives, and attempts to impose her or his interpretation about the facts to others by violent means or not. From this stance, any other perspective is taken to be false a priori and, accordingly, as a putative target to be suppressed or adapted to the privileged way of thinking. We argue, instead, for a more fallibilist evaluation of our own beliefs and a more respectful appraisal of the diversity of students’ beliefs by both students and teachers. (shrink)

It is a well-known fact that Ernst Cassirer was inspired by his colleague, the biologist Jakob von Uexkiill at the university of Hamburg. This paper claims this inspiration was double—affecting both Cassirer's philosophical anthropology and Cassirer's epistemology of biology, but in two rather different ways. Thus, the paper intends to shed light on a corner of the history of the development of German thought of the interwar period. It may also have an actual interest because both Cassirer and Uexkiill enjoy, (...) for the time being and each in their way, a renaissance, e.g. in the recent field of biosemiotics. (shrink)

​This book investigates the nature of aesthetic experience and aesthetic objects. Written by leading philosophers, psychologists, literary scholars and semioticians, the book addresses two intertwined issues. The first is related to the phenomenology of aesthetic experience: The understanding of how human beings respond to artworks, how we process linguistic or visual information, and what properties in artworks trigger aesthetic experiences. The examination of the properties of aesthetic experience reveals essential aspects of our perceptual, cognitive, and semiotic capacities. The second issue (...) studied in this volume is related to the ontology of the work of art: Written or visual artworks are a specific type of objects, containing particular kinds of representation which elicit a particular kind of experience. The research question explored is: What properties in artful objects trigger this type of experience, and what characterizes representation in written and visual artworks? The volume sets the scene for state-of-the-art inquiries in the intersection between the psychology and ontology of art. The investigations of the relation between the properties of artworks and the characteristics of aesthetic experience increase our insight into what art is. In addition, they shed light on essential properties of human meaning-making in general. (shrink)
