In this paper I consider two different perspectives on aesthetic experience. On the one hand, there is the tradition of Plato that proposes a metaphysical representation of the world in which sensible and over-sensible are rigidly separated. On the other hand, the early Chinese tradition of Daoism suggests an undivided experience of the world in which the aesthetic engagement with the myriad things (wanwu 萬物) makes actions effective. In particular, I consider how the Zhuangzi, one of the main books of (...) philosophical Daoism, offers an excellent opportunity to rethink the aesthetic experience of the world not as subordinated to epistemology or to the supersensible but as a possibility to adapt oneself to changing circumstances.

The work of Thomas Kuhn has been very influential in Anglo-American philosophy of science and it is claimed that it has initiated the historical turn. Although this might be the case for English speaking countries, in France an historical approach has always been the rule. This article aims to investigate the similarities and differences between Kuhn and French philosophy of science or ‘French epistemology’. The first part will argue that he is influenced by French epistemologists, but by lesser known authors (...) than often thought. The second part focuses on the reactions of French epistemologists on Kuhn’s work, which were often very critical. It is argued that behind some superficial similarities there are deep disagreements between Kuhn and French epistemology. This is finally shown by a brief comparison with the reaction of more recent French philosophers of science, who distance themselves from French epistemology and are more positive about Kuhn. Based on these diverse appreciations of Kuhn, a typology of the different positions within the philosophy of science is suggested. (shrink)

According to the so-called strong variant of Composition as Identity (CAI), the Principle of Indiscernibility of Identicals can be extended to composition, by resorting to broadly Fregean relativizations of cardinality ascriptions. In this paper we analyze various ways in which this relativization could be achieved. According to one broad variety of relativization, cardinality ascriptions are about objects, while concepts occupy an additional argument place. It should be possible to paraphrase the cardinality ascriptions in plural logic and, as a consequence, relative (...) counting requires the relativization either of quantifiers, or of identity, or of the is one of relation. However, some of these relativizations do not deliver the expected results, and others rely on problematic assumptions. In another broad variety of relativization, cardinality ascriptions are about concepts or sets. The most promising development of this approach is prima facie connected with a violation of the so-called Coreferentiality Constraint, according to which an identity statement is true only if its terms have the same referent. Moreover - even provided that the problem with coreferentiality can be fixed - the resulting analysis of cardinality ascriptions meets several difficulties. (shrink)

It is often claimed that epistemic bubbles and echo chambers foster post-truth by filtering our access to information and manipulating our epistemic attitude. In this paper, I try to add a further level of analysis by adding the issue of belief formation. Building on cognitive psychology work, I argue for a dual-system theory according to which beliefs derive from a default system and a critical system. One produces beliefs in a quasi-automatic, effortless way, the other in a slow, effortful way. (...) I also argue that digital socio-epistemic environments tend to inculcate disvalues in their agent's epistemic identity, a process that causes the cognitive shortcircuits typical of conspiracy theories.

In this article we consider argumentation as an epistemic process performed by an agent to extend and revise her beliefs and gain knowledge, according to the information provided by the environment. Such a process can also generate the suspension of the claim under evaluation. How can we account for such a suspension phenomenon in argumentation process? We propose: (1) to distinguish two kinds of suspensions – critical suspension and non-critical suspension – in epistemic change processes; (2) to introduce a Paraconsistent (...) Weak Kleene logic (PWK) based belief revision theory which makes use of the notion of topic to distinguish the two kinds of suspensions previously mentioned, and (3) to develop a PWK-style argumentation framework and its expansion. By doing that, we can distinguish two kinds of suspensions in an epistemic process by virtue of the notion of topic. (shrink)

What role does habit formation play in the development of sport skills? We argue that motor habits are both necessary for and constitutive of sensorimotor skill as they support an automatic, yet inherently intelligent and flexible, form of action control. Intellectualists about skills generally assume that what makes action intelligent and flexible is its intentionality, and that intentionality must be necessarily cognitive in nature to allow for both deliberation and explicit goal-representation. Against Intellectualism we argue that the habitual behaviours that (...) compose skilful action are accompanied by their specific, non-cognitive form of intentionality: this is motor intentionality, which is purposive and adaptive while involving no explicit deliberation or goal representation. Our account of habit based on Motor Intentionality explains why the formation of motor habits can sometimes act as the sole basis of skilful acquisition: Motor Intentionality is inherently purposeful because it is an embodied source of sensorimotor anticipation, pre-reflective motivation, and pragmatic know-how. Skill development through exercise always builds on a motor intentional component even when it is guided by Deliberate Practice to the point that, pace Intellectualism, Deliberate Practice is disclosed, not constrained, by habit formation. As suggested by the fact that repetitive exercises can play a major role in the development of flexible and intelligent sport skills, automatism is not a drawback for strategic control and improvisation but rather their pragmatic foundation.

In this short paper we consider Linnebo's thin/thick dichotomy: first, we show that it does not overlap with the very common one between abstract/concrete objects; second, on the basis of some difficulties with the distinction, we propose, as a possible way out, to move from thin/thick objects to thin/thick concepts.

Although implementation is ubiquitous in computer science, there is no systematic philosophical analysis of its metaphysical structure. In this article, I argue that the conceptual resources of analytical metaphysics can be very helpful in laying the foundations for a metaphysics of implementation and, by extension, of computer science. More specifically, I hold that implementation is a form of metaphysical grounding, and I show that, by combining the properties of grounding with the specific constraints of computer science, one can clarify what (...) a metaphysics of computer science could look like. In sections 2 and 3 of the article, I discuss various meanings of implementation, while in section 4, I submit my central claim that implementation is a form of metaphysical grounding. I substantiate this claim by showing that implementation and grounding share the same formal properties. If this is correct, then issues of ontological dependence, metaphysical explanation, hyperintensionality, and foundedness, typically associated with grounding, can be re-formulated in computer science using the concept of implementation. This is what I do in sections 5.1-5.4. I conclude with some general remarks about the future development of computer science's metaphysics. (shrink)

Among the contemporary philosophers using the concept of the Anthropocene, Bruno Latour and Isabelle Stengers are prominent examples. The way they use this concept, however, diverts from the most common understanding of the Anthropocene. In fact, their use of this notion is a continuation of their earlier work around the concept of a ‘parliament of things.’ Although mainly seen as a sociology or philosophy of science, their work can be read as philosophy of technology as well. Similar to Latour’s claim (...) that science is Janus-headed, technology has two faces. Faced with the Anthropocene, we need to shift from technologies of control to technologies of negotiations, i.e., a parliament of things. What, however, does a ‘parliament of things’ mean? This paper wants to clarify what is conceptually at stake by framing Latour’s work within the philosophy of Michel Serres and Isabelle Stengers. Their philosophy implies a ‘postlinguistic turn,’ where one can ‘let things speak in their own name,’ without claiming knowledge of the thing in itself. The distinction between object and subject is abolished to go back to the world of ‘quasi-objects’ (Serres). Based on the philosophy of science of Latour and Stengers the possibility for a politics of quasi-objects or a ‘cosmopolitics’ (Stengers) is opened. It is in this framework that their use of the notion of the Anthropocene must be understood and a different view of technology can be conceptualized. (shrink)

This paper motivates the idea that social robots should be credited as moral patients, building on an argumentative approach that combines virtue ethics and social recognition theory. Our proposal answers the call for a nuanced ethical evaluation of human-robot interaction that does justice to both the robustness of the social responses solicited in humans by robots and the fact that robots are designed to be used as instruments. On the one hand, we acknowledge that the instrumental nature of robots and (...) their unsophisticated social capabilities prevent any attribution of rights to robots, which are devoid of intrinsic moral dignity and personal status. On the other hand, we argue that another form of moral consideration—not based on rights attribution—can and must be granted to robots. The reason is that relationships with robots offer to the human agents important opportunities to cultivate both vices and virtues, like social interaction with other human beings. Our argument appeals to social recognition to explain why social robots, unlike other technological artifacts, are capable of establishing with their human users quasi-social relationships as pseudo-persons. This recognition dynamic justifies seeing robots as worthy of moral consideration from a virtue ethical standpoint as it predicts the pre-reflective formation of persistent affective dispositions and behavioral habits that are capable of corrupting the human user’s character. We conclude by drawing attention to a potential paradox drawn forth by our analysis and by examining the main conceptual conundrums that our approach has to face. (shrink)

Beall (2016) proposes to read the middle-value of Weak Kleene logic as off-topic. This interpretation has recently drawn some attention: for instance, Francez has pointed out that Beall's interpretation does not meet some important requirements to count as a truth value. Moreover, Beall is silent about what a topic (or a subject matter) is. But arguably, what is a topic? is a crucial question, and an answer is really important to fully understand his proposal. Thus, our goal here is to (...) help to remedy this deficiency, and show how Beall's interpretation of Weak Kleene truth-values interacts with the notion of topic. To do that, we formalize his motivating ideas and draw some consequences from them. (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)

Graham Priest has recently proposed a solution to the problem of the One and the Many which involves inconsistent objects and a non-transitive identity relation. We show that his solution entails either that the object everything is identical with the object nothing or that they are mutual parts; depending on whether Priest goes for an extensional or a non-extensional mereology.

The work of Michel Serres is often presented as a radical break with the work of Gaston Bachelard. The aim of this paper is to partly correct this image, by focusing on Serres’s early Hermes series (1969-1980). In these books Serres portrays himself as a follower of Bachelard, exemplarily shown in his neologism of the ‘new new scientific spirit’ (le nouveau nouvel esprit scientifique), updating Bachelard in the light of more recent scientific developments. This allows a reinterpretation of the relation (...) between both authors, one where there is room to acknowledge how the roots of Serres’s philosophy lie not in a radical break with Bachelard, but can be partly understood as a Bachelardian criticism of Bachelard himself. This Bachelardian criticism consists in what could be called his ‘surrationalism’: the sciences do not follow the categories imposed by philosophers, but are always more flexible and open than these categories allow. Specific critiques of Serres, such as those concerning the novelty of Bachelard’s thought, the role of epistemology and finally the political dimension of science will be evaluated through a reappraisal of this Bachelardian move that underlies Serres’s criticism.

Michel Serres’s proposal to extend the social contract to a natural contract has been met with criticism and misunderstanding. In this article, I would like to respond to common criticisms by reconsidering two central related concepts. It is claimed that we cannot represent nature’s interests and therefore cannot come to an agreement, and thus a contract, with nature. However, I will suggest a way out by reinterpreting representation and agreement. I will start with the problem of representation: nature cannot be (...) represented. Specifically, I will present two counterarguments. The first argument is that political representation is always difficult, even in the case of human beings. Representing nature only seems more difficult because we have forgotten the difficulties associated with representing humans. The second argument aims to rethink representation. Representing nature only seems so hard because we tend to follow a cognitive understanding of representation, as if representation is about representing the ideas of the represented party. Instead, following Michael Saward, I propose an alternative understanding of representation as a game of representative claims and counterclaims: political representation is about claiming to speak on behalf of a referent and then allowing that referent to respond to that claim. Then I turn to the problem of agreement. A natural contract seems difficult because it is hard to imagine what it would mean for nature to agree to a particular proposal. To counter this, I turn to the notion of symbiosis, found in the work of Serres. A natural contract, I will argue, need not be a contract of consensus or synthesis. The alternative is a contract of symbiosis, which does not require all parties to have a common understanding of the situation. Instead, it allows for an agreement in which all parties have their own interests and definition of the situation. In this sense, a natural contract can make sense if it is understood as a contract in which symbiosis is achieved through political representation based on a game of claims and counterclaims.

Synthetic biology aims to synthesize novel biological systems or redesign existing ones. The field has raised numerous philosophical questions, but most especially what is novel to this field. In this article I argue for a novel take, since the dominant ways to understand synthetic biology’s specificity each face problems. Inspired by the examination of the work of a number of chemists, I argue that synthetic biology differentiates itself by a new regime of articulation, i.e. a new way of articulating the (...) questions and phenomena it wants to address. Instead of describing actual existing biological systems, the field aims to describe biological possibilities. In the second part I corroborate this hypothesis through a comparison between early research in the field of the origins of life and contemporary synthetic biologists, who are not so much interested in the historical origin of life on Earth, but rather in a universal biology of the possible origins of any life whatsoever.

Ian Hacking’s Representing and Intervening is often credited as being one of the first works to focus on the role of experimentation in philosophy of science, catalyzing a movement which is sometimes called the “philosophy of experiment” or “new experimentalism”. In the 1980s, a number of other movements and scholars also began focusing on the role of experimentation and instruments in science. Philosophical study of experimentation has thus seemed to be an invention of the 1980s whose central figure is Hacking. (...) This article aims to assess this historical claim, made by Hacking himself as well as others. It does so first by highlighting how a broader perspective on the history of philosophy reveals this invention narrative to be incorrect, since experimentation was a topic of interest for earlier philosophers. Secondly, the article evaluates a revision of this historical claim also made by some philosophers of experiment: the rediscovery narrative, which frames Hacking and others as having rediscovered the work of these earlier authors. This second narratives faces problems as well. Therefore we develop a third narrative which we call the contextualist narrative. Rather than considering experimentation in an essentialist manner as a fixed research object that is either present or not in the work of specific authors, experimentation should be addressed through a narrative that asks in what way it becomes a philosophical problem for certain authors and for what purpose. Such contextualization enables a repositioning of Hacking’s philosophy of experiment in relation to the specific debates in which he intervened, such as the realism-antirealism debate, the Science Wars and the debate on incommensurability.

Conflicts between our best philosophical theories (BPTs) and our common beliefs are widespread. For example, if eliminativism is our BPT, then our BPT conflicts with common beliefs about the existence of middle-sized composite artifacts. “Compatibilism” is the name usually given to a theoretical attitude, according to which, in the case of a conflict between BPT and a common belief P, we should try to find a reconciliation. The two major variants of compatibilism are “semantic compatibilism” (SC) and “cognitive compatibilism” (CC). (...) According to SC, to be reconciled with BPT is the “real” version of the content of our ordinary assertions; according to CC, to be reconciled with BPT is the mental state we are “really” in while thinking P. In this paper, we present a new kind of compatibilism, epistemic compatibilism (EC). According to EC, to be reconciled with BPT is the explanation of why we believe that P. After presenting EC, we will argue that it fares better than SC and CC for at least two related reasons: EC does not rely on any form of what we call semantic or cognitive “recarving”; thus, EC avoids some sceptical problems that aect the other two versions of compatibilism.

Often associated with themes in political philosophy and aesthetics, the work of Jean-François Lyotard is most known for his infamous definition of the postmodern in his best-known book, La condition postmoderne, as incredulity towards metanarratives. The claim of this article is that this famous claim of Lyotard is actually embedded in a philosophy of technology, one that is, moreover, still relevant for understanding present technoscience. The first part of the article therefore sketches Lyotard’s philosophy of technology, mainly by correcting three (...) common misconceptions: that La condition postmoderne would only be about metanarratives, whereas in fact, it is mainly about what replaces them, namely performativity; that performativity would be shorthand for capitalism, whereas in reality, capitalism is the latest instance of a longer history of performativity; and that Lyotard’s reflections on science and technology would be restricted to this book alone, whereas in reality, a well-articulated philosophy of technology, centered around the concept of technoscience, is found in his later work. The second part of the article then aims to highlight the contemporary relevance of this philosophy of technoscience through a brief examination of two contemporary technosciences: synthetic biology and data science.

In ethical reflections on new technologies, a specific type of argument often pops up, which criticizes scientists for “playing God” with these new technological possibilities. The first part of this article is an examination of how these arguments have been interpreted in the literature. Subsequently, this article aims to reinterpret these arguments as symbolic arguments: they are grounded not so much in a set of ontological or empirical claims, but concern symbolic classificatory schemes that ground our value judgments in the (...) first place. Invoking symbolic arguments thus refers to how certain new technologies risk undermining our fundamental symbolic distinctions by which we organize and evaluate our interactions with the world and in society. Such symbolic distinctions, moreover, tend to be resilient against logical argumentation, mainly because they themselves form the basis on which we argue in the cultural and ethical sphere in the first place. Therefore, effective strategies to evaluate and counter these arguments require another approach, showing that these technologies either do not challenge these classifications or, if they do, how they can be accompanied by the proper actions to integrate these technologies into our society.

This article argues that pseudoscience lacks an adequate philosophical analysis. Using conspiracy theories as a case study, it is claimed that such an analysis needs to go beyond a mere epistemological approach. In the first part, it is shown that the existing philosophical literature shares the assumption that conspiracy theories are primarily deficient scientific hypotheses. This claim is contested, because such an approach can only understand what conspiracy theories fail to be, but not what they are and why people tend (...) to endorse them. To develop an alternative, the second part starts from recent sociology of science, applied to conspiracy theories, that claims that both true and false theories are in need of a symmetrical social explanation. However, this opens the path to relativism because it does not allow for a significant distinction between scientific and conspiracy theories. In the third section an alternative analysis of conspiracy theories is offered, which does not abandon this distinction. Moreover, it is claimed that the most important element of conspiracy theories is not their truth value but rather their symbolic structures of meaning. The aim of conspiracy theories, and perhaps of pseudoscience in general, is then not to know facts about the world, but rather to offer a meaningful framework within which to live. (shrink)

This article takes the scientific study of conspiracy theories itself as an object of inquiry. It looks at the three main frameworks to look at conspiracy theories: a psychological, epistemological and a sociological approach. These different approaches exist somewhat separately and often do not get along. The central claim that follows from a genealogy of these research programs is that the conflicts between these different approaches should be understood not merely as disagreements about how the world works, but as a (...) fundamental disagreement about the underlying diagnosis of what is at stake in conspiracy theories. In other words, the conflicts stem in part from political differences, not merely empirical ones. The purpose of this article is to bring these different diagnoses back into dialogue with each other and to point out that despite their differences, they also have something in common: a concern about the state of contemporary democratic institutions. Depending on which project one subscribes to, conspiracy thinking will appear either as the cause or the solution of these democratic concerns. (shrink)

In this paper we first develop a Dialetheic Logic with Exclusive Assumptions and Conclusions, DLEAC. We adopt the semantics of the logic of paradox (LP) extended with a notion of model suitable for DLEAC, and we modify its proof theory by refining the notions of assumption and conclusion, which are understood as speech acts. We introduce a new paradox – the rejectability paradox – first informally, then formally. We then provide its derivation in an extension of DLEAC contanining the rejectability (...) predicate.

The work of Gaston Bachelard is known for two crucial concepts, that of the epistemological rupture and that of phenomenotechnique. A crucial question is, however, how these two concepts relate to one another. Are they in fact essentially connected or must they be seen as two separate elements of Bachelard’s thinking? This paper aims to analyse the relation between these two Bachelardian moments and the significance of the concept of phenomenotechnique for today. This will be done by examining how the (...) concepts of Bachelard have been used from the 1960s on. From this historical perspective, one gets the impression that these two concepts are relatively independent from each other. The Althusserian school has exclusively focused on the concept of ‘epistemological break’, while scholars from Science & Technology Studies, such as Bruno Latour, seem to have only taken up the concept of phenomenotechnique. It in fact leads to two different models of how to think about science, namely the model of purification and the model of proliferation. The former starts from the idea that sciences are rational to the extent that they are purified and free from obstacles. Scientific objectivity, within this later model, is not achieved by eradicating all intermediaries, obstacles and distortions, but rather exactly by introducing as many relevant technical mediators as possible. Finally, such a strong distinction will be criticized and the argument will be made that both in Bachelard’s and Latour's thought both concepts are combined. This leads to a janus-headed view on science, where both the element of purification and the element of proliferation are combined. (shrink)

In his 2018 essay Down to Earth, the French philosopher Bruno Latour proposes a hypothesis that connects a number of contemporary issues, ranging from climate denialism to deregulation and growing inequality. While his hypothesis, namely that the elites act as if they live in another world and are leaving the rest of the world behind, might seem like a conspiracy theory, I will argue that there is a way to make sense of it. To do so, I will turn to (...) two other authors, Timothy Mitchell and Shoshana Zuboff, to highlight the kind of logic that Latour seems to have in mind. In the final section, I will propose to capture the commonalities of these authors through the concept of shifting reciprocities and will return to Latour’s political plea to define one’s territories, reinterpreted as reciprocities.

Following the speech act theory, we take hypotheses and assertions as linguistic acts with different illocutionary forces. We assume that a hypothesis is justified if there is at least a scintilla of evidence for the truth of its propositional content, while an assertion is justified when there is conclusive evidence that its propositional content is true. Here we extend the logical treatment for assertions given by Dalla Pozza and Garola by outlining a pragmatic logic for assertions and hypotheses. On the (...) basis of this extension we analyse the standard logical opposition relations for assertions and hypotheses. We formulate a pragmatic square of oppositions for assertions and a hexagon of oppositions for hypotheses. Finally, we give a mixed hexagon of oppositions to point out the opposition relations for assertions and hypotheses. (shrink)

The central claim of this article is that post-truth requires a political and socio-economical perspective, rather than a moral or epistemological one. The article consists of two parts. The first part offers a critical examination of the dominant analyses of post-truth in terms of shifting standards of the origin and the evaluation of facts. Moreover, the claim that postmodernism is the cause of post-truth is examined and refuted. In the second part an alternative perspective is developed, centring around the notion (...) of gatekeepers. Rather than linking post-truth to bullshit and postmodernism, it should be understood as a symptom of a contemporary shift in the gatekeepers of truth and knowledge. Knowledge and truth are always mediated in society through the hands of gatekeeping institutions such as journalism or science. Post-truth is a symptom of a broader transformation of the gatekeeping institutions of our current society. It therefore requires a political philosophy of these institutional shifts and the new risks they involve. (shrink)

In this article, two different claims about nature are discussed. On the one hand, environmental philosophy has forced us to reflect on our position within nature. We are not the masters of nature as was claimed before. On the other hand there are the recent developments within synthetic biology. It claims that, now at last, we can be the masters of nature we have never been before. The question is then raised how these two claims must be related to one (...) another. Rather than stating that they are completely irreconcilable, I will argue for a dialogue aimed to discuss the differences and similarities. The claim is that we should not see it as two successive temporal phases of our relation to nature, but two tendencies that can coexist. (shrink)

According to strong composition as identity, the logical principles of one–one and plural identity can and should be extended to the relation between a whole and its parts. Otherwise, composition would not be legitimately regarded as an identity relation. In particular, several defenders of strong CAI have attempted to extend Leibniz’s Law to composition. However, much less attention has been paid to another, not less important feature of standard identity: a standard identity statement is true iff its terms are coreferential. (...) We contend that, if coreferentiality is dropped, indiscernibility is no help in making composition a genuine identity relation. To this aim, we analyse as a case study Cotnoir’s theory of general identity, in which indiscernibility is obtained thanks to a revisionary semantics and true identity statements are allowed to connect non-coreferential terms. We extend Cotnoir’s strategy for indiscernibility to the relation of comaternity, and we show that, neither in the case of composition nor in that of comaternity, indiscernibility contibutes to show that they are genuine identity relations. Finally, we compare Cotnoir’s approach with other versions of strong CAI endorsed by Wallace, Bøhn, and Hovda, and canvass the extent to which they violate coreferentiality. The comparative analysis shows that, in order to preserve coreferentiality, strong CAI is forced to adopt a non-standard semantic treatment of the singular/plural distinction. (shrink)

The aim of this chapter is to show how Francophone PS, or what is called French (historical) epistemology, embodies this interconnectedness. Moreover, a novel approach to what constitutes French epistemology will be developed here, going beyond a purely historical survey or a reevaluation of a range of concepts found in this tradition.7 The aim is instead to highlight two methodological principles at work in French epistemology that are often in tension with one another, but are not recognized as such in (...) the literature.

In Lewis reconstructs set theory using mereology and plural quantification (MPQ). In his recontruction he assumes from the beginning that there is an infinite plurality of atoms, whose size is equivalent to that of the set theoretical universe. Since this assumption is far beyond the basic axioms of mereology, it might seem that MPQ do not play any role in order to guarantee the existence of a large infinity of objects. However, we intend to demonstrate that mereology and plural quantification (...) are, in some ways, particularly relevant to a certain conception of the infinite. More precisely, though the principles of mereology and plural quantification do not guarantee the existence of an infinite number of objects, nevertheless, once the existence of any infinite object is admitted, they are able to assure the existence of an uncountable infinity of objects. So, ifMPQ were parts of logic, the implausible consequence would follow that, given a countable infinity of individuals, logic would be able to guarantee an uncountable infinity of objects. (shrink)

Within continental philosophy of biology the work of Michel Serres has not received a lot of attention. Nonetheless, this chapter wants to argue that Serres was part of a group of thinkers – together with Jacques Monod and Henri Atlan – that started to think about biology in terms of second-order cybernetics and information theory. Therefore, this chapter aims to do four things. First of all, it maps the relation between Serres and Canguilhem, one that was mediated by authors such (...) as Louis Althusser or Jacques Monod. Secondly, it fleshes out Serres’s own ‘biophilosophy’. I label this alternative tradition as a ‘biophilosophy without a subject’. Finally, this chapter explores the consequences of this alternative biophilosophy through a brief examination of two authors whose work lies in the line of this tradition: René Girard and Bruno Latour. Though at first sight different, they both draw inspiration from this biophilosophy to develop a framework that, paradoxically, ‘jumps over’ the subject. Hence, the reason why biology is neither a prominent theme in Girard’s nor in Latour’s work. This is not because of a lack of biophilosophy, but because of an implicit one: a biophilosophy without a subject. (shrink)

In the 1951 Gibbs lecture, Gödel asserted his famous dichotomy, where the notion of informal proof is at work. G. Priest developed an argument, grounded on the notion of naïve proof, to the effect that Gödel’s first incompleteness theorem suggests the presence of dialetheias. In this paper, we adopt a plausible ideal notion of naïve proof, in agreement with Gödel’s conception, superseding the criticisms against the usual notion of naïve proof used by real working mathematicians. We explore the connection between (...) Gödel’s theorem and naïve proof so understood, both from a classical and a dialetheic perspective. (shrink)

Commonsense ontology often conflicts with the ontology of our best scientific and philosophical theories. However, commonsense ontology, and commonsense belief systems in general, seems to be remarkably efficient and cognitively fundamental. In cases of contrast, it is better to find a way to reconcile commonsense and ”theoretical” ontologies. Given that commonsense ontologies are typically expressed within natural language, a classical procedure of reconciliation is semantical. The strategy is that of individuating the ”ontologically problematic” expressions of natural language and paraphrasing the (...) sentences in which they appear in a (formal) language whose commitments are compatible with those of our best theories. We believe that this strategy of reconciliation, though quite standard, especially in the philosophical literature, is problematic: for a start, it forces us to conclude that the ”real content” of our commonsense expressions and beliefs is different from what it appears. Commonsense ontology becomes just an illusion. We will thus propose an alternative approach: according to our view, a commonsense ontology is reconciled with a theoretical ontology in case it is shown that the explanation of why we believe in the existence of a problematic entity is compatible with our best theories. We will call this kind of reconciliation ”epistemic”. The advantage of an epistemic reconciliation is that commonsense ontology is treated in its own right and could be taken prima facie. Another advantage of the view is that epistemic reconciliation can be analysed through the notion of explaining away: a commonsense ontology is epistemically reconciled with a theoretical ontology if and only if the problematic entities of the commonsense ontology are explained away by ”respectable” entities of the theoretical ontology. In the final part of the paper, we sketch a formal analysis of explaining away. (shrink)

This article argues that historical epistemology offers the history of philosophy and science more than a mere tool to write the history of concepts. It does this, first of all, by rereading historical epistemology through Michel Foucault's “techniques of the self.” Second, it turns to the work of Léon Brunschvicg and Gaston Bachelard. In their work we see a proposal for what the subjectivity of scientists and philosophers should be. The article thus argues that their work is driven by a (...) normative psychology: a set of prescriptions for which mental constitution a scholarly self has to have. In the Conclusion, it returns to existing analyses of “open‐mindedness” as a virtue and explores in what way these cases challenge these analyses, as well as to what extent Foucault's “techniques of the self” can be applied to other cases in the history of French philosophy.

This special issue aims to redress the balance and to open up Gaston Bachelard's work beyond a small in-crowd of experts and aficionado’s in France. It aims to stimulate the discovery of new and understudied aspects of Bachelard’s work, including aspects of the intellectual milieu he was working in. Fortunately, for this purpose we were able to rely both on renowned Bachelard specialists, such as Hans-Jörg Rheinberg-er, Cristina Chimisso and Dominique Lecourt, as well as on a number of younger scholars (...) who are discovering their work in a different intellectual context. At the same time we also want to reassess the value of this oeuvre, which also entails examining the reasons and causes of the relative neglect of Bachelard’s work in recent times. Has it exhausted its possibilities? Does it have intrinsic limitations that have contributed to the eclipse, as some influential, mainly French, philoso-phers have more or less explicitly suggested?

The Kolmogorov-Sinai entropy is a fairly exotic mathematical concept which has recently aroused some interest on the philosophers’ part. The most salient trait of this concept is its working as a junction between such diverse ambits as statistical mechanics, information theory and algorithm theory. In this paper I argue that, in order to understand this very special feature of the Kolmogorov-Sinai entropy, is essential to reconstruct its genealogy. Somewhat surprisingly, this story takes us as far back as the beginning of (...) celestial mechanics and through some of the most exciting developments of mathematical physics of the 19th century.

In view of the publication of the DSM-V researchers were asked to discuss the theoretical implications of the definition of mental disorders. The reasons for the use, in the DSM-III, of the term disorder instead of disease are considered. The analysis of these reasons clarifies the distinction between the general definition of disorder and its implicit, technical meaning which arises from concrete use in DSM disorders. The characteristics and limits of this technical meaning are discussed and contrasted to alternative definitions, (...) like Wakefield’s harmful/dysfunction analysis. It is shown that Wakefield’s analysis faces internal theoretical problems in addition to practical limits for its acceptance in the DSM-V. In particular, it is shown that: a) the term dysfunction is not purely factual but intrinsically normative/evaluative; b) it is difficult to clarify what dysfunctions are in the psychiatric context (the dysfunctional mechanism involved being unknown in most cases and the use of evolutionary theory being even more problematic); c) the use of conceptual analysis and commonsense intuition to define dysfunctions leaves unsatisfied empiricists; d) it is unlikely that the authors of the DSM-V will accept Wakefield’s suggestion to revise the diagnostic criteria of any single DSM disorder in accordance with his analysis, because this is an excessively extensive change and also because this would probably reduce DSM reliability. In conclusion, it is pointed up in which sense DSM mental disorders have to be conceived as constructs, and that this undermines the realistic search for a clear-cut demarcation criterion between what is disorder and what is not.

The aim of this paper is twofold: First, we present and develop a system of logic for pragmatics including the act of denial. Second, we analyse in our framework the so-called paradox of assertability. We show that it is possible to yield sentences that are not assertable. Moreover, under certain conditions, a symmetric result can be obtained: There is a specular paradox of deniability. However, this paradox is based on the problematic principle of classical denial equivalence.

The philosophy of Louis Althusser is often contrasted with the ideas of Michel Foucault. At first sight, the disagreement seems to be about the concept of ideology: while Althusser seem to be huge advocate of the use of the concept, Foucault apparently dislikes and avoids the concept altogether. However, I argue in this article that this reading is only superficial and that it obscures the real debate between these two authors. Althusser, especially in his recently posthumously published Sur la reproduction (...) (1995), appears to agree on many points with Foucault. The real dispute lies not in the concept of ideology, but in its connection with its counterpart ‘science’. Both Althusser and Foucault were in a way epistemologists, focusing on the question on how sciences develop and how scientific practice works. Focussing on their shared background in the French epistemology, with authors such as Gaston Bachelard and Jean Cavaillès, the real discussion appears to be about whether science can really be opposed to ideology or not. Focusing on these aspects of their works can shed new lights on their oeuvre as well as on the nature of scientific practice. (shrink)

This paper presents a semantical analysis of the Weak Kleene Logics Kw3 and PWK from the tradition of Bochvar and Halldén. These are three-valued logics in which a formula takes the third value if at least one of its components does. The paper establishes two main results: a characterisation result for the relation of logical con- sequence in PWK – that is, we individuate necessary and sufficient conditions for a set.

The pragmatic notion of assertion has an important inferential role in logic. There are also many notational forms to express assertions in logical systems. This paper reviews, compares and analyses languages with signs for assertions, including explicit signs such as Frege’s and Dalla Pozza’s logical systems and implicit signs with no specific sign for assertion, such as Peirce’s algebraic and graphical logics and the recent modification of the latter termed Assertive Graphs. We identify and discuss the main ‘points’ of these (...) notations on the logical representation of assertions, and evaluate their systems from the perspective of the philosophy of logical notations. Pragmatic assertions turn out to be useful in providing intended interpretations of a variety of logical systems. (shrink)
