Purpose. Our study aims at developing a conceptual model of transdisciplinary synthesis of philosophical-anthropological, sociopolitical and epistemological aspects of co-evolution of the scientific and technical designs of High Hume class and the socio-cultural / political context in the process of anthropo-socio-cultural genesis. The relevance of the topic is justified by the technologization of all spheres of human existence and the emergence of High Hume class technologies, which can be called technology-driven equally. As a result, the concepts of "bio-power" and (...) "biopolitics" have become ones of the most frequently mentioned in modern philosophical and anthropological discourse and attract increasing attention of philosophers, sociologists, and, in the last decadecades, experts in the field of practical political science and economics (Foucault, Agamben, Žižek, Kebnik, Nadesan, etc.). Theoretical basis. It is problem-theoretical research; We synthesize the results of our publications in recent years. We proceed from the fact that the main question of the informational phase of the development of a technogenic civilization lies in the rationalization and technologization of the evolutionary process, i.e. in the removal of the fundamental ontological antinomy “Evolution versus Reasonable Design”, as a result for modern neoliberal political democracy, biopower and its theoretical understanding (biopolitics) are effective tools and technologies to form of optimal trends of the global evolutionary process, in the framework of this ideological system. We have chosen the comparative conceptual analysis combining with the results of the content analysis of Web publications by the main method of the study. Originality of the research is in the fact that the central core of such a model is the use of a conceptual and terminological apparatus for describing the mechanisms of the progressive evolution of complex systems, known as the “triple spiral” by Ledeisdorf-Itskovich. This allowed us to integrate the bio-power phenomenon into the general scheme of a stable evolutionary strategy of a technogenic civilization. The conclusions. We justified the transformation of biopolitics into the main factor in the global evolution of self-organizing human-sized systems, including the biosphere as a whole. This is achieved through the creation of a specific (bio) ethical system of imperatives and the activities of individuals in relation to themselves and other agents of social actions. Bioethics with a trail of associated conceptual areas (biosociology, bioeconomics, biohistory, etc.) turned out to be the only rationalized regulator of the process of biological and sociocultural evolution. The triple spiral biotechnology – bioeconomy – bioenergy as the material substance of the life of technological civilization is reflected in the ideal world as a triad of bioethics – biosociology – biopolitics. Both triads form closed cycles of evolutionary transformations that transmit and amplify the initial momentum of transformations on each other through a cascade mechanism with positive feedback.

The article, first, reconstructs and criticizes Sandro Nannini’s incompatibilistic concept of freedom of decision and, second, develops a compatibilistic alternative, a synthesis of a rationalistic and an autonomous approach. Nannini justifies his conception primarily from a naturalistic point of view: it reflects our sense of agency, so he says. This is criticized as empirically wrong and methodically mistaken: The theory of freedom of decision is, actually, normative; it is about good decisions; naturalism cannot establish normative claims. The alternative is (...) based, methodically, on an idealizing hermeneutics, which tries to reconstruct the point of free decisions, and then justifies the resulting concept practically: Free decisions, conceived in this way, realize optimally our autonomous desires.

First I argue that the prohibition of linguistic self-reference as a solution to the antinomy problem contains a pragmatic contradiction and is thus not only too restrictive, but just inconsistent (chap.1). Furthermore, the possibilities of non-restrictive strategies for antinomy avoidance are discussed, whereby the explicit inclusion of the – pragmatically presuposed – consistency requirement proves to be the optimal strategy (chap.2). The central question here is that about the actual reason for antinomic structures. It turns out to be a (...) form of negative self-conditioning (chap.3). This makes it necessary to clarify the status of negative concepts (chap.4). The generalization of these considerations (chap.5) leads to the actual analysis of the antinomic basic structure (chap.6): Decisively for the pragmatics of the concept is that it positively owns a meaning, so that positivity is always constituted by the concept qua concept. Thus a negative concept is characterized by a fundamental ambivalence: From a semantic point of view it has negative character, in its pragmatic status as a concept, however, it has positive character. If the meaning is especially that of a negative self-reference, the ambivalence leads to the antinomic constellation of a negative self-condition – that is the crux of the matter here! The concept thus possesses the property defined by it exactly when it does not possess it and vice versa. A closer analysis shows that the function of reflective structures for the occurrence of antinomies has to be judged much more differentiated than previous opinions suggest. Not only are four forms of reflectivity to be distinguished in this context – ontic, semantic, pragmatic reflectivity, and especially the form of negative self-condition; but it is also apparent that these are intertwined with each other in a way that is difficult to be understood. The astonishing variety of relationships associated with this makes the irritation that has always emanated from the antinomy problem appear more comprehensible. In the developed pragmatic perspective furtheron parallels to the structure of self-consciousness become visible (chap.7). I conclude with considerations about the significance of the antinomic structure for the problem of dialectics, especially for the synthesis formation of mutually exclusive terms (chap.8). ---------- Zunächst wird gezeigt, dass das Verbot sprachlicher Selbstreferenz als Lösung des Antinomienproblems einen pragmatischen Widerspruch enthält und damit nicht nur zu restriktiv, sondern geradezu inkonsistent ist (Kap.1). Ferner werden Möglichkeiten nicht-restriktiver Strategien zur Antinomienvermeidung diskutiert, wobei sich die explizite Einbindung der – pragmatisch präsupponierten – Konsistenzforderung als optimale Strategie erweist (Kap.2). Zentral ist hier die Frage nach dem eigentlichen Grund antinomischer Strukturen. Er erweist sich als eine Form von negativer Selbst-Bedingung (Kap.3). Dies nötigt zu einer Klärung des Status negativer Begriffe (Kap.4). Die Verallgemeinerung dieser Überlegungen (Kap.5) leitet über zur eigentlichen Analyse der antinomischen Grundstruktur (Kap.6): Entscheidend zur Pragmatik des Begriffs gehört, dass ihm eine Bedeutung positiv zukommt, sodass durch den Begriff qua Begriff stets auch Positivität konstituiert ist. Dadurch ist ein negativer Begriff durch eine prinzipielle Ambivalenz gekennzeichnet: In semantischer Hinsicht hat er negativen Charakter, in seinem pragmatischen Status als Begriff hingegen positiven Charakter. Ist die Bedeutung insbesondere die eines negativen Selbstbezugs, führt die Ambivalenz zur antinomischen Konstellation einer negativen Selbst-Bedingung – das ist hier der springende Punkt! Der Begriff besitzt so die durch ihn definierte Eigenschaft genau dann, wenn er sie nicht besitzt und umgekehrt. Die nähere Analyse zeigt, dass hierbei die Funktion reflexiver Strukturen für das Auftreten von Antinomien weitaus differenzierter zu beurteilen ist, als bisherige Auffassungen nahelegen. Nicht nur dass in diesem Kontext vier Formen von Reflexivität – ontische, semantische, pragmatische Reflexivität und insbesondere auch die Form negativer Selbstbedingung – unterschieden werden müssen; es zeigt sich auch, dass diese in schwer durchschaubarer Weise ineinander verschränkt sind. Die damit verbundene erstaunliche Beziehungsvielfalt läßt die Irritation, die seit je vom Antinomienproblem ausging, begreiflicher erscheinen. In der entwickelten pragmatischen Perspektive werden ferner Parallelen zur Struktur von Selbstbewußtsein sichtbar (Kap.7). Ich schließe mit Überlegungen zur Bedeutung der antinomischen Struktur für das Problem der Dialektik, insbesondere zur Synthesebildung einander ausschließender Bestimmungen (Kap.8). (shrink)

The optimality approach to modeling natural selection has been criticized by many biologists and philosophers of biology. For instance, Lewontin (1979) argues that the optimality approach is a shortcut that will be replaced by models incorporating genetic information, if and when such models become available. In contrast, I think that optimality models have a permanent role in evolutionary study. I base my argument for this claim on what I think it takes to best explain an event. In certain contexts, optimality (...) and game-theoretic models best explain some central types of evolutionary phenomena. ‡Thanks to Michael Friedman, Helen Longino, Michael Weisberg, and especially Elliott Sober for comments on earlier drafts of this paper. †To contact the author, please write to: Department of Philosophy, Stanford University, Stanford, CA 94305-2155; e-mail: [email protected].

The fate of optimality modeling is typically linked to that of adaptationism: the two are thought to stand or fall together (Gould and Lewontin, Proc Relig Soc Lond 205:581–598, 1979; Orzack and Sober, Am Nat 143(3):361–380, 1994). I argue here that this is mistaken. The debate over adaptationism has tended to focus on one particular use of optimality models, which I refer to here as their strong use. The strong use of an optimality model involves the claim that selection is (...) the only important influence on the evolutionary outcome in question and is thus linked to adaptationism. However, biologists seldom intend this strong use of optimality models. One common alternative that I term the weak use simply involves the claim that an optimality model accurately represents the role of selection in bringing about the outcome. This and other weaker uses of optimality models insulate the optimality approach from criticisms of adaptationism, and they account for the prominence of optimality modeling (broadly construed) in population biology. The centrality of these uses of optimality models ensures a continuing role for the optimality approach, regardless of the fate of adaptationism. (shrink)

The Enhanced Indispensability Argument appeals to the existence of Mathematical Explanations of Physical Phenomena to justify mathematical Platonism, following the principle of Inference to the Best Explanation. In this paper, I examine one example of a MEPP—the explanation of the 13-year and 17-year life cycle of magicicadas—and argue that this case cannot be used defend the EIA. I then generalize my analysis of the cicada case to other MEPPs, and show that these explanations rely on what I will call ‘ (...) class='Hi'>optimal representations’, which are representations that capture all that is relevant to explain a physical phenomenon at a specified level of description. In the end, because the role of mathematics in MEPPs is ultimately representational, they cannot be used to support mathematical Platonism. I finish the paper by addressing the claim, advanced by many EIA defendants, that quantification over mathematical objects results in explanations that have more theoretical virtues, especially that they are more general and modally stronger than alternative explanations. I will show that the EIA cannot be successfully defended by appealing to these notions. (shrink)

Handbook entry on "Synthesis," surveying the roles played by synthesis in Husserl, important precursors in the history of philosophy, and the legacy of the term in Heidegger and Merleau-Ponty.

In this paper I examine the role of optimality reasoning in Aristotle’s natural science. By “optimality reasoning” I mean reasoning that appeals to some conception of “what is best” in order to explain why things are the way they are. We are first introduced to this pattern of reasoning in the famous passage at Phaedo 97b8-98a2, where (Plato’s) Socrates invokes “what is best” as a cause (aitia) of things in nature. This passage can be seen as the intellectual ancestor of (...) Aristotle’s own principle, expressed by the famous dictum “nature does nothing in vain but always what is best for the substance from among the possibilities concerning each kind of animal” (Progression of Animals II, 704b12-18). The paper is focused around exploring three questions that arise in connection with Aristotle’s use of this optimality principle: (1) How do we understand the concept of “the best” at work in the principle? (2) How does Aristotle conceive of “the range of possibilities”? And, finally, (3) what role does optimality reasoning play in Aristotle’s natural science? Is it a special form of demonstration in which the optimality principle functions as one of its premises, or is it a heuristic device that helps uncover those causally relevant features of a natural substances that ultimately serve as middle terms in demonstrations? In the final section I return to the comparison between Plato and Aristotle and argue that, while both see the natural world as the product of an optimizing agent and while both see this assumption as licensing a pattern of reasoning that appeals to a certain conception of “the best”, they disagree fundamentally over what the optimization agent is and how it operates. Thus, despite their general agreement, it would be a mistake to think that Aristotle simply took over Plato’s use of optimality reasoning without significant modifications. (shrink)

For most of their respective existences, reliabilism and evidentialism (that is, process reliabilism and mentalist evidentialism) have been rivals. They are generally viewed as incompatible, even antithetical, theories of justification.1 But a few people are beginning to re-think this notion. Perhaps an ideal theory would be a hybrid of the two, combining the best elements of each theory. Juan Comesana (forthcoming) takes this point of view and constructs a position called “Evidentialist Reliabilism.” He tries to show how each theory can (...) profit by borrowing elements from the other. Comesana concentrates on reliabilism’s problems and how it might be improved by infusions from evidentialism. This paper follows a similar tack. My emphasis, however, is the reverse of Comesana’s. I highlight problems for evidentialism and show how it could benefit by incorporating reliabilist themes. I am not sanguine that evidentialists will see it my way. They might even view my proposals as an insidious attempt to convert evidentialists to reliabilism. Well, I won’t debate the best way to formulate this paper’s recipe. At any rate, it began with the idea (which anteceded my reading of Comesana) of creating a synthesis of reliabilism and evidentialism. It retains significant strands of that idea, although the synthesis theme does not pervade the entire paper. What is mentalist evidentialism? Its original formulation was succinct. (shrink)

A response to Lindsay Craig's essay, The So-Called Extended Synthesis and Population Genetics.

A standard way to challenge convergence-based accounts of inductive success is to claim that they are too weak to constrain inductive inferences in the short run. We respond to such a challenge by answering some questions raised by Juhl (1994). When it comes to predicting limiting relative frequencies in the framework of Reichenbach, we show that speed-optimal convergence—a long-run success condition—induces dynamic coherence in the short run.

Abstract in English, German, French and Croatian -/- In the paper “The ‘Bubbling Up’ of Subterranean Politics in Europe”, which was published in 2013 in the Journal of Civil Society, Mary Kaldor and Sabine Selchow attempted to reveal the specific qualities of the uprisings which emerged after the year 2010 in some European countries, such as Germany, Spain, Italy, England etc. According to the authors, the mode of organization which forms the main body of these emancipatory movements obtains its basic (...) logic from the world of the Internet. The use of the Internet requires a re-evaluation of negative philosophical commentary regarding technology. In the context of twentieth-century philosophy, Martin Heidegger and Herbert Marcuse are the most influential philosophers who studied the negative aspects of technology. Heidegger portrayed the destructive effects of scientific reasoning and technology on the Western culture through the criticism of the traditional Western metaphysics on a phenomenological-ontological level. Marcuse, belonging to the tradition of Western Marxism, formed his critique of technology in the context of the concept of instrumental rationality and the critique of advanced industrial society and capitalism. Although the starting points of their perspectives on technology and the underlying purposes of their critiques of technology were different, it may be asserted that both have a rather negative and almost entirely pessimistic disposition towards technology. Heidegger’s and Marcuse’s criticisms of technology will be discussed in this context and the differences and similarities between these criticisms will be shown. Finally, the paper will emphasise the question of the possibility of a positive role of technology. Technology can serve as an alternative to negative uses by shedding light on the relation between the current uprisings and the Internet.

Zusammenfassung In dem Artikel „The ‘Bubbling Up’ of Subterranean Politics in Europe”, veröffentlicht im Jahre 2013 im Journal of Civil Society, versuchten Mary Kaldor und Sabine Selchow die spezifischen Qualitäten der Aufstände zum Ausdruck zu bringen, die nach 2010 in den europäischen Ländern ausbrachen – Deutschland, Spanien, Italien, England usw. Nach Ansicht der Autoren erhält der Modus der Organisation, der den Hauptkörper dieser emanzipatorischen Bewegungen bildet, seine grundlegende Logik aus der Welt des Internets. Die Analogie mit dem Internet erfor- dert eine Neubewertung der negativen Kommentare über die Technologie aus philosophischer Perspektive. Martin Heidegger und Herbert Marcuse sind die einflussreichsten Philosophen, die sich mit den negativen Aspekten der Technologie in der Philosophie des 20. Jahrhunderts befasst haben. Heidegger schilderte die zerstörerischen Auswirkungen der wissenschaftlichen Vernunft und Technologie auf die westliche Kultur durch die Kritik an der traditionellen abend- ländischen Metaphysik auf der phänomenologisch-ontologischen Ebene, während Marcuse, ein Mitglied des westlichen Marxismus, seine Kritik an der Technologie im Rahmen des Konzepts der instrumentellen Rationalität und der Kritik der fortgeschrittenen Industriegesellschaft und Kapitalismus geformt hat. Obgleich die Ansatzpunkte ihrer Perspektiven über die Technologie und die zugrunde liegenden Zwecke ihrer Kritik an der Technologie unterschiedlich waren, kann behauptet werden, dass beide eine eher negative und fast völlig pessimistische Einstellung zur Technologie hatten. In diesem Zusammenhang werden Heideggers und Marcuses Kritiken an der Technologie diskutiert sowie Unterschiede und Ähnlichkeiten zwischen den beiden Kri- tiken aufgezeigt. Abschließend unterstreicht das Paper die Frage nach der Möglichkeit einer positiven Rolle für die Technologie, die als Alternative zur negativen Perspektive dienen kann, indem sie Licht in das Verhältnis zwischen aktuellen Aufständen und Internet bringt.

Résumé Dans l’article « The “Bubbling Up” of Suberranean Politics in Europe » publié en 2013 dans Journal of Civil Society, Mary Kaldor et Sabine Selchow tentent de mettre en lumière les caractéristiques spécifiques des révoltes qui ont fait jour après 2010 dans certains pays européens – Allemagne, Espagne, Italie, Angleterre, etc. Selon nos auteures, le mode d’organisation qui a formé le corps essentiel de ces mouvements émancipatoires tire sa logique de base du monde de l’internet. Cette analogie avec l’internet requiert une réévaluation, à partir d’un point de vue philosophique, des commentaires négatifs sur la technologie. Martin Heidegger et Herbert Marcuse sont les philosophes les plus influents ayant travaillé sur les aspects négatifs de la technologie au sein de la philosophie du XXe siècle. Heidegger a dépeint les effets destructeurs de la raison scientifique et de la technologie de notre culture occidentale à travers son criticisme de la métaphysique traditionnelle occidentale à un niveau phénoménologico-ontologique, tandis que Marcuse, membre du « communisme occidentale », a formé une critique de la technologie au sein du concept de rationalité instrumentale et une critique de la société industrielle avancée et du capitalisme. Bien que le point de départ de leur perspective sur la technologie et que le but sous-jacent de leur critique diffèrent, il est possible d’affirmer que leur point commun est d’avoir posé un regard négatif et presque entièrement pessimiste sur la technologie. À cet égard, le criticisme d’Heidegger et de Marcuse vont être abordés afin d’en soulever les différences et les similarités. Enfin, cet article mettra l’accent sur la possibilité d’un rôle positif de la technologie qui pourrait servir d’alternative aux perspectives négatives en faisant la lumière sur le lien entre les révoltes actuelles et l’internet.

Sažetak U članku »The ‘Bubbling Up’ of Subterranean Politics in Europe«, objavljenom 2013. u časopisu Journal of Civil Society, Mary Kaldor i Sabine Selchow pokušale su otkriti specifične značajke pobuna koje su se javila nakon 2010. godine u europskim zemljama poput Njemačke, Španjolske, Italije, Engleske itd. Prema autoricama, način organiziranja koji čini glavno tijelo ovih emancipatornih pokreta preuzima svoju osnovnu logiku iz svijeta Interneta. Analogija s Internetom zahtijeva ponovnu evaluaciju negativnih komentara o tehnici iz filozofske perspektive. Martin Heidegger i Herbert Marcuse najutjecajniji su filozofi 20. stoljeća koji su se bavili negativnim aspektima tehnike. Heidegger je prikazao destruktivne učinke znanstvene racionalnosti i tehnike na zapadnu kulturu kroz kritiku tradicionalne zapadne metafizike na fenomenološko-ontološkoj razini, dok je Marcuse, kao predstavnik zapadnoga marksizma, oblikovao svoju kritiku tehnike u kontekstu pojma instrumentalne racionalnosti te kritike razvijenog industrijskog društva i kapitalizma. Iako su polazišne točke njihovih pogleda na tehniku, kao i osnovne svrhe kritike tehnike, različite, može se reći da obojica imaju poprilično negativno i gotovo u potpunosti pesimističko shvaćanje tehnologije. U tom će se kontekstu razmotriti Heideggerova i Marcuseova kritika tehnike kao i razlike i sličnosti između tih dvaju pristupa. Zaključno će rad naglasiti mogućnost pozitivne uloge tehnike, koja može služiti kao alternativa negativnoj perspektivi osvjetljavajući odnos između nedavnih pobuna i interneta.

It is shown here that an analogous result holds in a much more general model. Firstly, the result follows from a more basic principle than expected-utility maximisation, namely from an axiom (Epistemic Monotonicity) which requires neither utilities nor prior probabilities of the ‘correctness’ of alternatives. Secondly, a person’s input need not (...) be a vote for an alternative, it may be any type of input, for instance a subjective degree of belief or probability of the correctness of one of the alternatives. The case of a profile of subjective degrees of belief is particularly appealing, since here no parameters such as competence parameters need to be known. (shrink)

Talk at University of Turin, 'Kant, oltre Kant, May 5th 2023. --- -/- It is useful, while keeping in mind a holistic approach, to concentrate on a common theme in Kant’s text, which it will turn out is the quintessential element of his novel ‘way of thinking’, as he himself put it in preface of the second edition of the Critique of Pure Reason. This common theme is the idea of synthesis, which is what holds together, and is the (...) entryway to, all the other familiar aspects of Kant’s thought: his concept of self-consciousness or how mind is involved in cognition, his ideas about the role of the imagination, his theory of knowledge and his metaphysics of experience, and not unimportantly, its relation to what is probably the most Kantian element here: the categories of the understanding as the first principles of knowledge. But the meaning of synthesis and its role in its various facets, though frequently the subject of discussion in papers and monographs alike, is hardly understood in contemporary Kant scholarship. Most readings of the text of the Deduction, the part in which Kant elucidates his concept of synthesis, exhibit a shallow, mechanical understanding of it. -/- A compounding factor is that synthesis can’t really be understood independently of the other aforementioned elements of Kant’s thought. Grasping the meaning of synthesis implies coming to grips with his concept of self-consciousness and the way both self-consciousness and the categories are intricately and intimately involved. Most interpretations consider these aspects too much as if they were indeed separable faculties or entities that serve separable functions, undercutting an important feature of Kant’s metaphysics: the possibility of a priori unified cognition, for which an indivisible self-legislating subject is responsible. Rather, they are expressions of various aspects of a singular function of the mind as the ground of possible unified knowledge. -/- One striking example of such a superficial reading of the text is the way the relation between figurative synthesis and intellectual synthesis—or in the case of the A-Deduction the threefold synthesis—is standardly interpreted, as if the two are independent or quasi-independent functions of different faculties of the mind, the imagination and the understanding. In this paper, I focus on the relation between figurative and intellectual synthesis, while arguing that failing to understand this properly, indeed the relation between the imagination and the understanding, leads to a vicious regress in the explanation of the ground of knowledge, for which a priori synthesis is specifically designed. In other words, failing to see the intimate relation between the imagination and the understanding, the very identity that lies at their root, risks losing sight of the primary aim of Kant’s thought: the possibility of a priori unified knowledge.

Today a change is imperative in approaching global problems: what is needed is not arm-twisting and power politics, but searching for ways of co-evolution in the complex social and geopolitical systems of the world. The modern theory of self-organization of complex systems provides us with an understanding of the possible forms of coexistence of heterogeneous social and geopolitical structures at different stages of development regarding the different paths of their sustainable co-evolutionary development. The theory argues that the evolutionary channel to (...) the observed increasing complexity is extremely narrow and only certain discrete spectra of relatively stable self-maintained structures are feasible in complex systems. There exists a restricted set of ways of assembling a complex evolutionary whole from diverse parts. The law of nonlinear synthesis of complex structures reads: the integration of structures in more complex ones occurs due to the establishment of a common tempo of their evolution. On the basis of the theory, we can see not only desirable but also attainable futures. (shrink)

To be optimistic, it is standardly assumed, is to have positive expectations. I here argue that this definition is correct but captures only one variety of optimism – here called factual optimism. It leaves out two other important varieties of optimism. The first – focal optimism – corresponds to the idea of seeing the glass half full. The second – axiological optimism – consists in the view that good is stronger than bad. Those three varieties of optimism are irreducible to (...) each other and do not belong to a common kind. I define each of these, characterize their respective correctness conditions, and contrast hope with optimism. (shrink)

In this essay, I evaluate four central metaethical readings of Spinoza’s moral philosophy in the literature: unqualified anti-realism, qualified anti-realism, qualified realism, and unqualified realism. More specifically, I discuss the metaethical readings of Charles Jarrett (unqualified anti-realism), Matthew Kisner (qualified anti-realism), Jon Miller (qualified realism), and Andrew Youpa (unqualified realism), each of which captures core aspects of this debate. My conclusions are that (1) Spinoza is neither an unqualified anti-realist nor an unqualified realist and (2) Spinoza’s ethical framework represents a (...) qualified synthesis of realist (naturalistic) and anti-realist (affective) features.

We consider several natural fragments of the alternating-time temporal logics ATL* and ATL with restrictions on the nesting between temporal operators and strategic quantifiers. We develop optimal decision procedures for satisfiability in these fragments, showing that they have much lower complexities than the full languages. In particular, we prove that the satisfiability problem for state formulae in the full `strategically flat' fragment of ATL* is PSPACE-complete, whereas the satisfiability problems in the flat fragments of ATL and ATL$^{+}$ are $\Sigma^P_3$-complete. (...) We note that the nesting hierarchies for fragments of ATL* collapse in terms of expressiveness above nesting depth 1, hence our results cover all such fragments with lower complexities.

This article examines two questions about scientists’ search for knowledge. First, which search strategies generate discoveries effectively? Second, is it advantageous to diversify search strategies? We argue pace Weisberg and Muldoon, “Epistemic Landscapes and the Division of Cognitive Labor”, that, on the first question, a search strategy that deliberately seeks novel research approaches need not be optimal. On the second question, we argue they have not shown epistemic reasons exist for the division of cognitive labor, identifying the errors that (...) led to their conclusions. Furthermore, we generalize the epistemic landscape model, showing that one should be skeptical about the benefits of social learning in epistemically complex environments. (shrink)

This synthesis of 5 prominent conflict management paradigms uses power differential as the single most contributing variable to their process and outcome of conflict. Efforts of scholars to integrate or synthesize conflict paradigms have been unsuccessful or clumsy by the scholars’ own assessments. The 5 selected paradigms represent an interdisciplinary set of normative and descriptive paradigms from different social contexts and intellectual frameworks. The 5 share the common traits of rival goals, three levels of socially constructed power differential, and (...) outcomes relative to the total value of the rival goal. An inverse relationship between power differential and the total value of conflict outcomes is supported by all 5 paradigms and empirical data. Explanatory metatheory is the methodology used for synthesis. An increase in power differential results in a decrease in total value of the rival goal. Power differential is constructed using Max Weber’s ideal-type method. The power differentials are abstracted from the paradigms themselves. Empirical work form secondary sources and case studies complete the analysis. (shrink)

Evolutionary theory is undergoing an intense period of discussion and reevaluation. This, contrary to the misleading claims of creationists and other pseudoscientists, is no harbinger of a crisis but rather the opposite: the field is expanding dramatically in terms of both empirical discoveries and new ideas. In this essay I briefly trace the conceptual history of evolutionary theory from Darwinism to neo-Darwinism, and from the Modern Synthesis to what I refer to as the Extended Synthesis, a more inclusive (...) conceptual framework containing among others evo–devo, an expanded theory of heredity, elements of complexity theory, ideas about evolvability, and a reevaluation of levels of selection. I argue that evolutionary biology has never seen a paradigm shift, in the philosophical sense of the term, except when it moved from natural theology to empirical science in the middle of the 19th century. The Extended Synthesis, accordingly, is an expansion of the Modern Synthesis of the 1930s and 1940s, and one that—like its predecessor—will probably take decades to complete. (shrink)

The value of optimality modeling has long been a source of contention amongst population biologists. Here I present a view of the optimality approach as at once playing a crucial explanatory role and yet also depending on external sources of confirmation. Optimality models are not alone in facing this tension between their explanatory value and their dependence on other approaches; I suspect that the scenario is quite common in science. This investigation of the optimality approach thus serves as a case (...) study, on the basis of which I suggest that there is a widely felt tension in science between explanatory independence and broad epistemic interdependence, and that this tension influences scientific methodology.

In this paper, I propose a novel interpretation of the role of the understanding in generating the unity of space and time. On the account I propose, we must distinguish between the unity that belongs to determinate spaces and times – which is a result of category-guided synthesis and which is Kant’s primary focus in §26 of the B-Deduction, including the famous B160–1n – and the unity that belongs to space and time themselves as all-encompassing structures. Non-conceptualist readers of (...) Kant have argued that this latter unity cannot be the product of categorial synthesis. While they are correct that this unity is not the product of any particular act of category-guided synthesis, I argue that conceptualists are right to nevertheless attribute this unity to the understanding. I argue that it is a result of what we can think of as the ‘original’ synthesis of understanding and sensibility themselves – it is a synthesis, moreover, in which the whole is logically prior to the parts.

The development of student's skills in the conduct of research, both qualitative and quantitative, is envisioned in the K to12 curriculum. This study uses qualitative research to show students' perceptions and understanding of a particular issue. Similarly, it describes apparent cultures postulated within the students' chosen themes. Finally, it determines the development of cultural knowledge in the context of Merleau-Ponty's phenomenology of perception among Grade 11 students at a Senior High School near Laguna Lake in the City of San Pedro, (...) Laguna, Philippines, during the school year 2016-2017. Semi-structured interviews, focus group discussions, and triangulation was used to obtain students' cultural understanding and share their experiences undertaking diverse qualitative research using purposive sampling. The data was analyzed using phenomenological analysis. Students' perceptions and streams of consciousness include street children, child labor fishermen, and school violence. Cultural understanding encompasses (a) the economic and psychological implications of family, (2) camaraderie, pakikisama and pakikiisa, and (3) education as a survival strategy. Senior High School students' research experiences connect underpinnings of cultural understanding. (shrink)

Austere relationism rejects the orthodox analysis of hallucinations and illusions as incorrect perceptual representations. In this article, I argue that illusions of optimal motion present a serious challenge for this view. First, I submit that austere-relationist accounts of misleading experiences cannot be adapted to account for IOMs. Second, I show that any attempt at elucidating IOMs within an austere-relationist framework undermines the claim that perceptual experiences fundamentally involve relations to mind-independent objects. Third, I develop a representationalist model of IOMs. (...) The proposed analysis combines two ideas: Evans' dynamic modes of presentation and Fine's relational semantics for identity. (shrink)

Abstract: In this work, polystyrene/waste tires composites were prepared by incorporating of waste tires into polydisperse commercial polystyrene in a melt-mixing method. The rheological characterization of PS and PS/composite have been studied and compared. These properties were studied using ARES-Rheometer under nitrogen atmosphere in parallel plate geometry with diameter 8 mm. The measurements are carried out over a wide range of temperatures ranged from 120°C to 220°C and frequencies from 100 to 0.1 radians per second. The complex modulus (G*) were (...) evaluated and compared with those of unfilled PS. The dynamic mechanical properties and stability at elevated temperatures were found to increase with the addition of waste tires to PS as confirmed by the results. The results showed that the value of G* at  = 1.0 radian/s is 1.8104 and 4.4104 Pa for PS and PS/waste tires, respectively. This difference rises at low frequencies-branch to be the value of G* at  = 0.06 radian/s is 8.8102 and 7.8103 Pa for PS and PS/waste tires, respectively. Generally G* increases by the addition of rubber as filler for PS . (shrink)

Recent debates between proponents of the modern evolutionary synthesis (the standard model in evolutionary biology) and those of a possible extended synthesis are a good example of the fascinating tangle among empirical, theoretical, and conceptual or philosophical matters that is the practice of evolutionary biology. In this essay, we briefly discuss two case studies from this debate, highlighting the relevance of philosophical thinking to evolutionary biologists in the hope of spurring further constructive cross-pollination between the two fields.

In an intriguing but neglected passage in the Transcendental Deduction, Kant appears to link the synthetic activity of the understanding in experience with the phenomenon of attention (B156-7n). In this paper, we take up this hint, and draw upon Kant's remarks about attention in the Anthropology to shed light on the vexed question of what, exactly, the understanding's role in experience is for Kant. We argue that reading Kant's claims about synthesis in this light allows us to combine two (...) aspects of Kant's views that many commentators have thought are in tension with one another: on the one hand, Kant's apparent commitment to naïve realism about perception and, on the other, his apparent commitment to the necessity of synthetic activity by the understanding for any kind of cognitive contact with external objects.

In this paper an empirical theory about the nature of intention is sketched. After stressing the necessity of reckoning with intentions in philosophy of action a strategy for deciding empirically between competing theories of intention is exposed and applied for criticizing various philosophical theories of intention, among others that of Bratman. The hypothesis that intentions are optimality beliefs is defended on the basis of empirical decision theory. Present empirical decision theory however does not provide an empirically satisfying elaboration of the (...) desirability concepts used in these optimality beliefs. Based on process theories of deliberation two hypotheses for filling this gap are developed. (shrink)
