Interview with Carmen De Schryver on her work on Paulin Hountondji.

In a previous issue of Tijdschrift voor Filosofie, Filip Buekens argues that evolutionary psychology (EP), or some interpretations thereof, have a corrosive impact on our ‘manifest self-image’. Buekens wants to defend and protect the global adequacy of this manifest self-image in the face of what he calls evolutionary revisionism. Although we largely agree with Buekens’ central argument, we criticize his analysis on several accounts, making some constructive proposals to strengthen his case. First, Buekens’ argument fails to target EP, because his (...) notion of the ‘constitutive conditions’ of our attitudes is too wide and too extensive. Second, his defense of the global adequacy of our attitudes does not allow for sufficient differentiation to analyze the problem of potential self-refutation with respect to EP. Third, his account of knowledge about constitutive conditions, and its impact on our self-image, is problematic. We provide a more detailed explanation for the pervasiveness of evolutionary revisionism and other misconceptions about EP. Finally, we consider in what sense EP may legitimately affect our self-image, and whether it can truly inspire corrections of our view of human nature. (shrink)

How Galileo Galilei discovered the law of fall, and the difference that this makes Galileo’s law of fall is one of the crucial building blocks of classical mechanics. The question how this law was discovered has often been a topic of debate. This article offers a reconstruction of the developments within Galileo’s research that led to the discovery of the law. This reconstruction is offered to make a philosophical point regarding the epistemic status of experimental results: Galileo’s experiments can offer (...) sufficient justification for the acceptance of the law of fall only because of their place in a broad research programme.

Short introduction to concepts and dilemma's of research ethics. Some historical notes concerning scientific research and applied ethics.

Review of a comprehensive introduction to a philosophy of the environment. Refers to the United Nations Brundtland-report (1987) and its ground-breaking definition of "sustainable development". Account of dilemma's of wants and needs of future generations. Notes and comments on Garrett Hardin, Tragedy of the commons (1968), Jacques Ellul, The technological society (1964) and Langdon Winner, Autonomous technology (1977). Study ends with a well-founded plea for an ecological society.

Critical comments on two roads to a good society. (These roads in response to John Rawls' A theory of justice, 1971): Dutch ethical theorist Trudy van Asperen (Het bedachte leven, 1993), and Avishai Margalit (A decent society, 1996).

Review of author of Risikogesellschaft. Auf dem Weg in eine andere Moderne (1986), Ulrich Beck. Five essays from Politik in der Risikogesellschaft (1990) and other titles (M. Hajer & M. Schwarz introd. eds.; transl. I. van der Aart).

In dit artikel betwist ik het gangbare idee dat de rede ontoereikend is voor morele motivatie, met name in relatie tot universele ethische kwesties. Door een uitgebreide verkenning van de Dual-Process Theory (DPT) stel ik dat onze morele intuïties zowel trainbaar zijn als een inherente neiging hebben naar universalistische overwegingen. Ik betoog dat sociale rechtvaardiging en de drang naar rationele argumentatie een cruciale rol spelen in het vormen en veranderen van onze morele standpunten. Concluderend pleit ik voor een herwaardering van (...) klassiek moreel redeneren en stel ik dat een universele ethiek psychologisch realistischer is dan eerder werd aangenomen. (shrink)

A political history and philosophy of the European Union. The journey of European states in their ungoing efforts from 1951 on (the Schuman Plan). Democracy, its political institutions and philosophical foundations, compared to Alexis de Tocqueville, De la démocratie en Amérique (two volumes, 1835, 1840; transl.: Democracy in Europe, London 1994) and a wide range of political theorists.

Physicist and philosopher of science Stephen Toulmin (London 1922 - Los Angeles 2009) published his last book Return to Reason in 2001 (Cambridge, MA). Review of translation in Dutch (2001). Introductory notes on his scholarly book reception in the Netherlands: An Examination of the Place of Reason in Ethics (1950), Wittgenstein's Vienna (1972, with Allan Janik), Cosmopolis.

Toulmin presents a fascinating historical and systematic plea for moral practice, practical reason and reflection in medical, political and moral issues. Michel de Montaigne's Essais (1580) supply stepping stones towards practical wisdom and "life with uncertainty". (shrink)

In dit artikel wordt de dominante metafysische oriëntatie in de hedendaagse meta-ethiek kritisch onder de loep genomen. Het hedendaagse debat, dat zich voornamelijk richt op de vraag hoe moraliteit metafysisch gezien 'in de werkelijkheid past', wordt gekenmerkt door een reeks complexe en soms esoterische discussies die, zo wordt betoogd, weinig bijdragen aan ons filosofische begrip van ethiek. Deze focus op metafysische grondslagen heeft geleid tot een tunnelvisie, waarin het debat gevangen zit tussen steeds ingewikkeldere vormen van non-cognitivisme, herconceptualisaties van 'objectiviteit' (...) en metafysische acrobatiek. Als alternatief wordt voorgesteld de aandacht in de meta-ethiek te verleggen naar het domein van praktisch redeneren. Door ons te concentreren op de patronen van geldige praktische argumentatie en het soort overwegingen dat mensen daadwerkelijk overtuigt, kunnen we wellicht een beter inzicht krijgen in de aard van ethische normativiteit en de rol ervan in ons leven. Het artikel pleit voor een meer pragmatische en minder metafysisch beladen benadering van de meta-ethiek, die zich richt op de daadwerkelijke praktijken van moreel redeneren en argumenteren.

The theories of belief change developed within the AGM-tradition are not logics in the proper sense, but rather informal axiomatic theories of belief change. Instead of characterizing the models of belief and belief change in a formalized object language, the AGM-approach uses a natural language — ordinary mathematical English — to characterize the mathematical structures that are under study. Recently, however, various authors such as Johan van Benthem and Maarten de Rijke have suggested representing doxastic change within a formal (...) logical language: a dynamic modal logic. Inspired by these suggestions Krister Segerberg has developed a very general logical framework for reasoning about doxastic change: dynamic doxastic logic (DDL). This framework may be seen as an extension of standard Hintikka-style doxastic logic with dynamic operators representing various kinds of transformations of the agent's doxastic state. Basic DDL describes an agent that has opinions about the external world and an ability to change these opinions in the light of new information. Such an agent is non-introspective in the sense that he lacks opinions about his own belief states. Here we are going to discuss various possibilities for developing a dynamic doxastic logic for introspective agents: full DDL or DDL unlimited. The project of constructing such a logic is faced with difficulties due to the fact that the agent’s own doxastic state now becomes a part of the reality that he is trying to explore: when an introspective agent learns more about the world, then the reality he holds beliefs about undergoes a change. But then his introspective (higher-order) beliefs have to be adjusted accordingly. In the paper we shall consider various ways of solving this problem. (shrink)

Toon van Eijk: Spinoza in het licht van bewustzijnsontwikkeling De beroemde filosoof Spinoza is moeilijk te doorgronden. Emeritus hoogleraar Maarten van Buuren heeft in 2016 twee boeken over Spinoza gepubliceerd, waarin hij diens filosofie op nauwgezette en verhelderende manier analyseert. Volgens Van Buuren is de kern van Spinoza’s ethiek de bevrijding van bevoogding en het streven om in overeenstemming te leven met de wereld en met zichzelf. Een aantal sleutelbegrippen in Spinoza’s filosofie zijn de immanente, in de natuur-inwonende God, (...) zelfbeschikking, de rede, intuïtie, macht en zelftoe-eigening. In dit boek bespreekt Toon van Eijk deze sleutelbegrippen aan de hand van de analyse van Van Buuren en de filosofie van Maharishi Mahesh Yogi, de grondlegger van de Transcendente Meditatie (TM) techniek. Filosofische begrippen blijven echter tandeloos zonder mogelijkheden om deze ideeën te verwerkelijken. Een synthese van filosofisch redeneren en praktijken voor bewustzijnsontwikkeling is nodig. Hoewel Spinoza een ethiek zonder metafysica voorstond, is Van Eijk van mening dat daadwerkelijk wijs handelen moeilijk zonder enige metafysische bagage kan. (shrink)

Philosophers of science have given up on the quest for a silver bullet to put an end to all pseudoscience, as such a neat formal criterion to separate good science from its contenders has proven elusive. In the literature on critical thinking and in some philosophical quarters, however, this search for silver bullets lives on in the taxonomies of fallacies. The attractive idea is to have a handy list of abstract definitions or argumentation schemes, on the basis of which one (...) can identify bad or invalid types of reasoning, abstracting away from the specific content and dialectical context. Such shortcuts for debunking arguments are tempting, but alas, the promise is hardly if ever fulfilled. Different strands of research on the pragmatics of argumentation, probabilistic reasoning and ecological rationality have shown that almost every known type of fallacy is a close neighbor to sound inferences or acceptable moves in a debate. Nonetheless, the kernel idea of a fallacy as an erroneous type of argument is still retained by most authors. We outline a destructive dilemma we refer to as the Fallacy Fork: on the one hand, if fallacies are construed as demonstrably invalid form of reasoning, then they have very limited applicability in real life. On the other hand, if our definitions of fallacies are sophisticated enough to capture real-life complexities, they can no longer be held up as an effective tool for discriminating good and bad forms of reasoning. As we bring our schematic “fallacies” in touch with reality, we seem to lose grip on normative questions. Even approaches that do not rely on argumentation schemes to identify fallacies fail to escape the Fallacy Fork, and run up against their own version of it. (shrink)

What makes beliefs thrive? In this paper, we model the dissemination of bona fide science versus pseudoscience, making use of Dan Sperber's epidemiological model of representations. Drawing on cognitive research on the roots of irrational beliefs and the institutional arrangement of science, we explain the dissemination of beliefs in terms of their salience to human cognition and their ability to adapt to specific cultural ecologies. By contrasting the cultural development of science and pseudoscience along a number of dimensions, we gain (...) a better understanding of their underlying epistemic differences. Pseudoscience can achieve widespread acceptance by tapping into evolved cognitive mechanisms, thus sacrificing intellectual integrity for intuitive appeal. Science, by contrast, defies those deeply held intuitions precisely because it is institutionally arranged to track objective patterns in the world, and the world does not care much about our intuitions. In light of these differences, we discuss the degree of openness or resilience to conceptual change (evidence and reason), and the divergent ways in which science and pseudoscience can achieve cultural “success”.

The scientific study of living organisms is permeated by machine and design metaphors. Genes are thought of as the ‘‘blueprint’’ of an organism, organisms are ‘‘reverse engineered’’ to discover their functionality, and living cells are compared to biochemical factories, complete with assembly lines, transport systems, messenger circuits, etc. Although the notion of design is indispensable to think about adaptations, and engineering analogies have considerable heuristic value (e.g., optimality assumptions), we argue they are limited in several important respects. In particular, the (...) analogy with human-made machines falters when we move down to the level of molecular biology and genetics. Living organisms are far more messy and less transparent than human-made machines. Notoriously, evolution is an opportunistic tinkerer, blindly stumbling on ‘‘designs’’ that no sensible engineer would come up with. Despite impressive technological innovation, the prospect of artificially designing new life forms from scratch has proven more difficult than the superficial analogy with ‘‘programming’’ the right ‘‘software’’ would suggest. The idea of applying straightforward engineering approaches to living systems and their genomes— isolating functional components, designing new parts from scratch, recombining and assembling them into novel life forms—pushes the analogy with human artifacts beyond its limits. In the absence of a one-to-one correspondence between genotype and phenotype, there is no straightforward way to implement novel biological functions and design new life forms. Both the developmental complexity of gene expression and the multifarious interactions of genes and environments are serious obstacles for ‘‘engineering’’ a particular phenotype. The problem of reverse-engineering a desired phenotype to its genetic ‘‘instructions’’ is probably intractable for any but the most simple phenotypes. Recent developments in the field of bio-engineering and synthetic biology reflect these limitations. Instead of genetically engineering a desired trait from scratch, as the machine/engineering metaphor promises, researchers are making greater strides by co-opting natural selection to ‘‘search’’ for a suitable genotype, or by borrowing and recombining genetic material from extant life forms.

Recent scientific research has settled on a purely descriptive definition of happiness that is focused solely on agents’ psychological states (high positive affect, low negative affect, high life satisfaction). In contrast to this understanding, recent research has suggested that the ordinary concept of happiness is also sensitive to the moral value of agents’ lives. Five studies systematically investigate and explain the impact of morality on ordinary assessments of happiness. Study 1 demonstrates that moral judgments influence assessments of happiness not only (...) for untrained participants, but also for academic researchers and even in those who study happiness specifically. Studies 2 and 3 then respectively ask whether this effect may be explained by general motivational biases or beliefs in a just world. In both cases, we find evidence against these explanations. Study 4 shows that the impact of moral judgments cannot be explained by changes in the perception of descriptive psychological states. Finally, Study 5 compares the impact of moral and non-moral value, and provides evidence that unlike non-moral value, moral value is part of the criteria that govern the ordinary concept of happiness. Taken together, these studies provide a specific explanation of how and why the ordinary concept of happiness deviates from the definition used by researchers studying happiness. (shrink)

People generally accept that there is causation by omission—that the omission of some events cause some related events. But this acceptance elicits the selection problem, or the difficulty of explaining the selection of a particular omissive cause or class of causes from the causal conditions. Some theorists contend that dependence theories of causation cannot resolve this problem. In this paper, we argue that the appeal to norms adequately resolves the selection problem for dependence theories, and we provide novel experimental evidence (...) for it. (shrink)

This paper discusses the ecological case for epistemic innocence: does biased cognition have evolutionary benefits, and if so, does that exculpate human reasoners from irrationality? Proponents of ‘ecological rationality’ have challenged the bleak view of human reasoning emerging from research on biases and fallacies. If we approach the human mind as an adaptive toolbox, tailored to the structure of the environment, many alleged biases and fallacies turn out to be artefacts of narrow norms and artificial set-ups. However, we argue that (...) putative demonstrations of ecological rationality involve subtle locus shifts in attributions of rationality, conflating the adaptive rationale of heuristics with our own epistemic credentials. By contrast, other cases also involve an ecological reframing of human reason, but do not involve such problematic locus shifts. We discuss the difference between these cases, bringing clarity to the rationality debate. (shrink)

Relationalism maintains that perceptual experience involves, as part of its nature, a distinctive kind of conscious perceptual relation between a subject of experience and an object of experience. Together with the claim that perceptual experience is presentational, relationalism is widely believed to be a core aspect of the naive realist outlook on perception. This is a mistake. I argue that naive realism about perception can be upheld without a commitment to relationalism.

Philosophers and psychologists often assume that mirror reflections are optical illusions. According to many authors, what we see in a mirror appears to be behind it. I discuss two strategies to resist this piece of dogma. As I will show, the conviction that mirror reflections are illusions is rooted in a confused conception of the relations between location, direction, and visibility. This conception is unacceptable to those who take seriously the way in which mirrors contribute to our experience of the (...) world. My argument may be read as an advertisement of the neglected field of philosophical catoptrics, the philosophical study of the optical properties of mirrors. It enables us to recast familiar issues in the philosophy of perception. (shrink)

True beliefs are better guides to the world than false ones. This is the common-sense assumption that undergirds theorizing in evolutionary epistemology. According to Alvin Plantinga, however, evolution by natural selection does not care about truth: it cares only about fitness. If our cognitive faculties are the products of blind evolution, we have no reason to trust them, anytime or anywhere. Evolutionary naturalism, consequently, is a self-defeating position. Following up on earlier objections, we uncover three additional flaws in Plantinga's latest (...) formulation of his argument: a failure to appreciate adaptive path dependency, an incoherent conception of content ascription, and a conflation of common-sense and scientific beliefs, which we diagnose as the ‘foundationalist fallacy’. More fundamentally, Plantinga's reductive formalism with respect to the issue of cognitive reliability is inadequate to deal with relevant empirical details. (shrink)

What is wrong with ad hoc hypotheses? Ever since Popper’s falsificationist account of adhocness, there has been a lively philosophical discussion about what constitutes adhocness in scientific explanation, and what, if anything, distinguishes legitimate auxiliary hypotheses from illicit ad hoc ones. This paper draws upon distinct examples from pseudoscience to provide us with a clearer view as to what is troubling about ad hoc hypotheses. In contrast with other philosophical proposals, our approach retains the colloquial, derogative meaning of adhocness, and (...) calls attention to the way in which the context of a theoretical move bears on the charge of adhocness. We also discuss the role of motivations implicit in the concept of adhocness, and the way ad hoc moves draw on theory-internal rationalizations. (shrink)

Many people assume that fictional entities are encapsulated in the world of fiction. I show that this cannot be right. Some works of fiction tell us about pieces of poetry, music, or theatre written by fictional characters. Such creations are fictional creations, as I will call them. Their authors do not exist. But that does not take away that we can perform, recite, or otherwise generate actual instances of such works. This means we can bring such individuals actually into existence, (...) as the works they are. I conclude that the assumption about encapsulation is untenable, unless an exception is made for types.

John Hyman insists that Frege-style cases for depiction show that any sound theory of depiction must distinguish between the ‘sense’ and the ‘reference’ of a picture. I argue that this rests on a mistake. Making sense of the cases does not require the distinction.

People can come to seem to us more beautiful the better we get to know their personalities. Some have taken this to show there is a moral kind of beauty. According to the moral beauty view, moral personality traits realise moral beauty in people. Here I present a problem for the standard articulation of the moral beauty view, namely that it is not a logical truth that people inherit the beauty of their virtues. I call this the ‘inheritance problem’. I (...) present an alternative articulation of the moral beauty view that does not give rise to the problem. On this alternative articulation, the moral beauty view is not as revisionary as it is standardly taken to be. (shrink)

In this commentary on Daniel Dennett's 'From Bacteria to Bach and Back', I make some suggestions to strengthen the meme concept, in particular the hypothesis of cultural parasitism. This is a notion that has both caused excitement among enthusiasts and raised the hackles of critics. Is the “meme” meme itself an annoying piece of malware, which has infected and corrupted the mind of an otherwise serious philosopher? Or is it an indispensable theoretical tool, as Dennett believes, which deserves to be (...) spread far and wide? (shrink)

At the intersection of aesthetics and the philosophy of perception lies a problem about representational images. When you look at Vermeer's View of Delft, do you in fact get to see Delft? It would be nice if we could answer in the affirmative, as it would so neatly explain many of our practices in engaging with images. Be it in churches, advertising, or psychology labs, we typically use images as substitutes for the immediate perception of things. Here is what I (...) claim: Images make it possible to see the objects they represent, and they do so because they can function in vision as perceptual mediators. A perceptual mediator is an object of perception by means of which we can perceive something wholly distinct from it. I show that, while such perceptual mediators may be exceptional in vision, in other sensory modalities they occur universally. Our sensory lives would be impoverished without the possibility of perceiving things mediately. In Chapter 1 I identify a fundamental dispute about images. The dispute is about whether images represent by making absent scenes appear to a viewer, or by merely copying the way an object or event looks. Many philosophers favour the idea that images merely copy how things look. In Chapter 2 I explain my dissatisfaction with the copy view. I lay out my main positive proposal in Chapter 3. How does the idea that images make absent objects visible fit with our current concept of perception? I formulate my answer through a study of the other sensory modalities. In audition, it is no mystery that sounds can make other things heard. My arguments forge a connection between images and sounds that has not been explored in recent work on representation or perception. I show how it offers an attractive solution to our problem. In Chapter 4, I argue that moreover, we may regard mediate perception as a purely sensory mode of perception. There is no need to rely on non-sensory or quasi-sensory effects of thought or cognition. Instead, coming to see a painted surface as an image consists in no more than discovering a previously unseen aspect of our visible surroundings. In Chapter 5 I consider at a more general level how visual images contribute to visual perception. Overall, I establish how visual representation has a structural place in our visual world. (shrink)

Why did R.G. Collingwood come to reject the adversarial style of philosophical discussion so popular among his Oxford peers? The main aim of this paper is to explain that Collingwood came to reject his colleagues’ specific style of philosophical dialogue on methodological grounds, and to show how the argument against adversarial philosophical discussion is integrated with Collingwood’s overall criticism of realist philosophy. His argument exploits a connection between method and practice that should be taken seriously even today.

In this paper we raise the question whether technological artifacts can properly speaking be trusted or said to be trustworthy. First, we set out some prevalent accounts of trust and trustworthiness and explain how they compare with the engineer’s notion of reliability. We distinguish between pure rational-choice accounts of trust, which do not differ in principle from mere judgments of reliability, and what we call “motivation-attributing” accounts of trust, which attribute specific motivations to trustworthy entities. Then we consider some examples (...) of technological entities that are, at first glance, best suited to serve as the objects of trust: intelligent systems that interact with users, and complex socio-technical systems. We conclude that the motivation-attributing concept of trustworthiness cannot be straightforwardly applied to these entities. Any applicable notion of trustworthy technology would have to depart significantly from the full-blown notion of trustworthiness associated with interpersonal trust. (shrink)

Este trabalho apresenta algumas considerações a respeito da Base Nacional Comum Curricular (BNCC), no referente às questões ligadas ao ensino da língua portuguesa no Brasil, à territorialidade e ao pertencimento racial, processos históricos, que envolvem, no campo da educação, a formação docente e a construção da cidadania dos educandos e das educandas nestes tempos de reafirmação do Estado democrático de direito e da vaga decolonial. Portanto, trata-se de uma abordagem política em termos do pensamento de Paulo Freire, patrono da educação (...) brasileira, que considerava político o ato de educar (FREIRE, 1980; 1983; 1989; 1996). É com base nesta perspectiva que a BNCC será abordada, mas sob o aporte teórico da análise pragmática do discurso, tributária da análise discursivo-desconstrutiva (cf. ARAÚJO, 2020). (shrink)

In arguing for his theory of pure reflective judgments of taste Kant extensively analyses beauty, but almost wholly disregards ugliness. We commonly take ugliness as paradigmatic when we reflect on our negative aesthetic judgments, and so does Kant. Consequently, there ought to be a more explicit story explaining how Kantian judgments of ugliness are possible. In this paper I argue that a disharmony is the key to understanding Kantian ugliness. This way, an answer to the question of ugliness in Kant (...) can be given in terms of a disharmonious free play of the faculties of imagination and understanding. (shrink)

Members of the field of philosophy have, just as other people, political convictions or, as psychologists call them, ideologies. How are different ideologies distributed and perceived in the field? Using the familiar distinction between the political left and right, we surveyed an international sample of 794 subjects in philosophy. We found that survey participants clearly leaned left (75%), while right-leaning individuals (14%) and moderates (11%) were underrepresented. Moreover, and strikingly, across the political spectrum, from very left-leaning individuals and moderates to (...) very right-leaning individuals, participants reported experiencing ideological hostility in the field, occasionally even from those from their own side of the political spectrum. Finally, while about half of the subjects believed that discrimination against left- or right-leaning individuals in the field is not justified, a significant minority displayed an explicit willingness to discriminate against colleagues with the opposite ideology. Our findings are both surprising and important, because a commitment to tolerance and equality is widespread in philosophy, and there is reason to think that ideological similarity, hostility, and discrimination undermine reliable belief formation in many areas of the discipline.

Central to many discussions of motivated reasoning is the idea that it runs afoul of epistemic normativity. Reasoning differently about information supporting our prior beliefs versus information contradicting those beliefs, is frequently equated with motivated irrationality. By analyzing the normative status of belief polarization, selective scrutiny, biased assimilation and the myside bias, I show this inference is often not adequately supported. Contrary to what’s often assumed, these phenomena need not indicate motivated irrationality, even though they are instances of belief-consistent information (...) processing. Second, I engage with arguments purporting to show that belief-consistent information processing does not indicate motivated irrationality because of its mere differential treatment of confirming and non-confirming evidence, but rather because it reveals the undermining presence of an irrelevant influence, such as a desire or partisan identity-driven cognition. While linking belief-consistent reasoning to a deeper source of directional motivation to make good on the claim that it indicates motivated irrationality is indeed what’s needed, two prominent such arguments fail. The non-normativity of many reasoning processes often taken to indicate motivated irrationality is not in fact well established. (shrink)

Lethal Autonomous Weapons (LAWs) are robotic weapons systems, primarily of value to the military, that could engage in offensive or defensive actions without human intervention. This paper assesses and engages the current arguments for and against the use of LAWs through the lens of achieving more ethical warfare. Specific interest is given particularly to ethical LAWs, which are artificially intelligent weapons systems that make decisions within the bounds of their ethics-based code. To ensure that a wide, but not exhaustive, survey (...) of the implications of employing such ethical devices to replace humans in warfare is taken into account, this paper will engage on matters related to current scholarship on the rejection or acceptance of LAWs—including contemporary technological shortcomings of LAWs to differentiate between targets and the behavioral and psychological volatility of humans—and current and proposed regulatory infrastructures for developing and using such devices. After careful consideration of these factors, this paper will conclude that only ethical LAWs should be used to replace human involvement in war, and, by extension of their consistent abilities, should remove humans from war until a more formidable discovery is made in conducting ethical warfare.

Is ruling out the possibility that one is dreaming a requirement for a knowledge claim? In “Philosophical Scepticism and Everyday Life” (1984), Barry Stroud defends that it is. In “Others Minds” (1970), John Austin says it is not. In his defense, Stroud appeals to a conception of objectivity deeply rooted in us and with which our concept of knowledge is intertwined. Austin appeals to a detailed account of our scientific and everyday practices of knowledge attribution. Stroud responds that what Austin (...) says about those practices is correct in relation to the appropriateness of making knowledge claims, but that the skeptic is interested in the truth of those claims. In this paper, we argue that Stroud’s defense of the alleged requirement smuggles in a commitment to a kind of internalism, which asserts that the perceptual justification available to us can be characterized independently of the circumstances in which we find ourselves. In our reading of Austin, especially of Sense & Sensibilia, he rejects that kind of internalism by an implicit commitment to what is called today a “disjunctive” view of perception. Austin says that objectivity is an aspect of knowledge, and his disjunctivism is part of an explanation of why the alleged requirement is not necessary for a knowledge claim. Since both Stroud and Austin are committed to the objectivity of knowledge, Stroud may ask which view of perceptual knowledge is correct, whether the internalist or the disjunctive. We argue that by paying closer attention to what Austin says about our practices of knowledge attribution, one can see more clearly that it is grounded not only on a conception of objectivity, but also on a conception of ourselves as information agents, a conception that is as deeply rooted as that of the objectivity of knowledge. This gives us moral and practical reasons to favor the disjunctive view of perception. (shrink)

Are identity criteria grounding principles? A prima facie answer to this question is positive. Specifically, two-level identity criteria can be taken as principles related to issues of identity among objects of a given kind compared with objects of a more basic kind. Moreover, they are grounding metaphysical principles of some objects with regard to others. In the first part of the paper we criticise this prima facie natural reading of identity criteria. This result does not mean that identity criteria could (...) not be taken as grounding principles. In the second part, we propose some basic steps towards a conceptual reading of grounding. Such a way of understanding it goes along with an epistemic reading of identity criteria. (shrink)

This paper discusses the possibility of an absolute vacuum - a space without any substance. The motivation of this study is the contrast between most philosophers, up to Descartes, who stated that a vacuum was impossible, and the 17th century change of outlook, when the possibility and effective existence of the vacuum was accepted after the experiments of Torricelli and Pascal. This article attempts to show that, contrary to the received opinion, the acceptance of an ether is preferable to the (...) acceptance of a vacuum for several reasons. First: it is impossible to provide an empirical proof of the non-existence of the ether; second, an absolute vacuum is unthinkable; third, the ether concept is useful for the understanding of physical phaenomena; and fourth, the hypothesis of an ether in apparently void spaces is useful for the future development of science. The paper also endeavours to show that no recent advance of science changed those conclusions and that no future development can change them. (shrink)

Speculative fiction, such as science fiction and fantasy, has a unique epistemic value. We examine similarities and differences between speculative fiction and philosophical thought experiments in terms of how they are cognitively processed. They are similar in their reliance on mental prospection, but dissimilar in that fiction is better able to draw in readers (transportation) and elicit emotional responses. By its use of longer, emotionally poignant narratives and seemingly irrelevant details, speculative fiction allows for a better appraisal of the consequences (...) of philosophical ideas than thought experiments.

We provide here irrefutable facts that prove the falsehood of the claims published in [1] by Dehmer and Mowshowitz (DM) against our paper published in [2]. We first prove that Dehmer’s definition of node probability [3] is flawed. In addition, we show that it was not Dehmer in [3] who proposed this definition for the first time. We continue by proving how the use of Dehmer’s definition does not reveal all the physico-mathematical richness of the walk entropy of graphs. Finally, (...) we show a few facts about the failure of DM themselves to cite properly the relevant literature in their field. We also show here how the Editors of Complexity have failed to manage the publication of [1] in an appropriate way according to the accepted guidelines given in the Code of Conduct and Best Practice Guidelines for Journal Editors, published by the Committee on Publication Ethics (COPE).
