The building of a global model of carcinogenesis is one of modern biology’s greatest challenges. The traditional somatic mutation theory is now supplemented by a new approach, called the Tissue Organization Field Theory. According to TOFT, the original source of cancer is loss of tissue organization rather than genetic mutations. In this paper, we study the argumentative strategy used by the advocates of TOFT to impose their view. In particular, we criticize their claim of incompatibility used to justify the necessity (...) to definitively reject SMT. First, we note that since it is difficult to build a non-ambiguous experimental demonstration of the superiority of TOFT, its partisans add epistemological and metaphysical arguments to the debate. This argumentative strategy allows them to defend the necessity of a paradigm shift, with TOFT superseding SMT. To do so, they introduce a notion of incompatibility, which they actually use as the Kuhnian notion of incommensurability. To justify this so-called incompatibility between the two theories of cancer, they move the debate to a metaphysical ground by assimilating the controversy to a fundamental opposition between reductionism and organicism. We show here that this argumentative strategy is specious, because it does not demonstrate clearly that TOFT is an organicist theory. Since it shares with SMT its vocabulary, its ontology and its methodology, it appears that a claim of incompatibility based on this metaphysical plan is not fully justified in the present state of the debate. We conclude that it is more cogent to argue that the two theories are compatible, both biologically and metaphysically. We propose to consider that TOFT and SMT describe two distinct and compatible causal pathways to carcinogenesis. This view is coherent with the existence of integrative approaches, and suggests that they have a higher epistemic value than the two theories taken separately. (shrink)

This paper is devoted to computer modelling of the development and regeneration of multicellular biological structures. Some species are able to regenerate parts of their body after amputation damage, but the global rules governing cooperative cell behaviour during morphogenesis are not known. Here, we consider a simplified model organism, which consists of tissues formed around special cells that can be interpreted as stem cells. We assume that stem cells communicate with each other by a set of signals, and that the (...) values of these signals depend on the distance between cells. Thus the signal distribution characterizes location of stem cells. If the signal distribution is changed, then the difference between the initial and the current signal distribution affects the behaviour of stem cells—e.g. as a result of an amputation of a part of tissue the signal distribution changes which stimulates stem cells to migrate to new locations, appropriate for regeneration of the proper pattern. Moreover, as stem cells divide and form tissues around them, they control the form and the size of regenerating tissues. This two-level organization of the model organism, with global regulation of stem cells and local regulation of tissues, allows its reproducible development and regeneration. (shrink)

In this paper the language of first-order modal logic is enriched with an operator @ ('actually') such that, in any model, the evaluation of a formula @A at a possible world depends on the evaluation of A at the actual world. The models have world-variable domains. All the logics that are discussed extend the classical predicate calculus, with or without identity, and conform to the philosophical principle known as serious actualism. The basic logic relies on the system K, whereas others (...) correspond to various properties that the actual world may have. All the logics are axiomatized. (shrink)

In this article we present a new kind of computing device that uses biochemical reactions networks as building blocks to implement logic gates. The architecture of a computing machine relies on these generic and composable building blocks, computation units, that can be used in multiple instances to perform complex boolean functions. Standard logical operations are implemented by biochemical networks, encapsulated and insulated within synthetic vesicles called protocells. These protocells are capable of exchanging energy and information with each other through transmembrane (...) electron transfer. In the paradigm of computation we propose, protoputing, a machine can solve only one problem and therefore has to be built specifically. Thus, the programming phase in the standard computing paradigm is represented in our approach by the set of assembly instructions that directs the wiring of the protocells that constitute the machine itself. To demonstrate the computing power of protocellular machines, we apply it to solve a NP-complete problem, known to be very demanding in computing power, the 3-SAT problem. We show how to program the assembly of a machine that can verify the satisfiability of a given boolean formula. Then we show how to use the massive parallelism of these machines to verify in less than 20 min all the valuations of the input variables and output a fluorescent signal when the formula is satisfiable or no signal at all otherwise.

The Enzymatic control reactions model was presented within the scope of fractional calculus. In order to accommodate the usual initial conditions, the fractional derivative used is in Caputo sense. The methodologies of the three analytical methods were used to derive approximate solution of the fractional nonlinear system of differential equations. Two methods use integral operator and the other one uses just an integral. Numerical results obtained exhibit biological behavior of real world problem.

The field of synthetic biology is looking forward engineering framework for safely designing reliable de-novo biological functions. In this undertaking, Computer-Aided-Design environments should play a central role for facilitating the design. Although, CAD environment is widely used to engineer artificial systems the application in synthetic biology is still in its infancy. In this article we address the problem of the design of a high level language which at the core of CAD environment. More specifically the Gubs language is a specification (...) language used to describe the observations of the expected behaviour. The compiler appropriately selects components such that the observation of the synthetic biological function resulting to their assembly complies to the programmed behaviour. (shrink)

The classic model of blood pressure regulation by Guyton et al. set a new standard for quantitative exploration of physiological function and led to important new insights, some of which still remain the focus of debate, such as whether the kidney plays the primary role in the genesis of hypertension. Key to the success of this model was the fact that the authors made the computer code freely available and eventually provided a convivial user interface for exploration of model behavior (...) on early microcomputers. Ikeda et al. developed an offshoot of the Guyton model targeting especially the regulation of body fluids and acid–base balance; their model provides extended renal and respiratory functions and would be a good basis for further extensions. In the interest of providing a simple, useable version of Ikeda et al.’s model and to facilitate further such extensions, we present a practical implementation of the model of Ikeda et al., using the ODE solver Berkeley Madonna.

In this paper, I investigate a system of quantified modal logic, due in many respects to Bressan (see [2]), from several perspectives -- both semantic and proof-theoretic. As Anderson and Belnap note in [1]: "It seems to be generally conceded that formal systems are natural or substantial if they can be looked at from several points of view. We tend to think of systems as artificial or ad hoc if most of their formal properties arise from some one notational system (...) in terms of which they are described." My efforts in this paper will be in part to lend substantiality to the system in question. Several formulation of the system are given and proved equivalent in appropriate senses. Also, some comments are made concerning possible alternative formulations. (shrink)

Providing a novel multi-disciplinary theorization of memory politics, this insightful Handbook brings varied literatures into a focused dialogue on the ways in which the past is remembered and how these influence transnational, interstate, and global politics in the present. With case studies from Africa, East and Southeast Asia, Europe, South America, and the United States, the Handbook focuses on the political features of historical memory in international relations. Chapters examine key concepts of memory politics, including accountability, commemoration and memorialization, the (...) Europeanization of memory, and the politics of trauma and victimhood, as well as analyzing different sites of memory, from the human body and memorial sites to media, film, and television. It also answers essential questions such as who and what determines the relevance of the past in the present; how does memory become a political question; and what are the political effects and ethical implications of its mobilization? Exploring the links between the politics of memory, international ethics, law, and diplomacy, this stimulating Handbook will be essential reading for students and scholars of politics and international relations, cultural studies, history, and transitional justice. Its discussion of notable agents and practices of memory politics will also be beneficial for practitioners working in human rights, politics, and public policy. (shrink)

The word 'actually' often refers to what is in fact the case, but it also often points to what would have been the case in a possible situation that is being envisaged. To capture such nuances, the formal languages discussed in the paper add subscripts to modal operators; in the model theory the subscripts allow an actuality operator to turn the evaluation of a formula to a world introduced by a preceding possibility or necessity operator having the same subscript. The (...) paper covers both propositional and predicate logic and proves the completeness of axiomatizations that extend standard modal systems beginning with K. (shrink)

Existentialism about propositions is the view that a proposition expressed in a sentence containing a nonempty name or indexical depends ontologically on the referent of the name or indexical: the proposition could not exist if the referent did not. The paper focuses on names. It discusses some arguments for existentialism and then presents a novel one. That argument does not presuppose that propositions have constituents, and it could be accepted by those who hold broadly Fregean views about names. It shows (...) that, for example, if Aristotle had not existed, no sentence could have meant that Aristotle is a philosopher. The paper also touches on the consequences of existentialism. (shrink)

This review of Turner’s “Computational Artifacts” focuses on one of the key novelties of the book, namely the proposal to understand the nature of computer programs as a “trinity” of specification, symbolic program, and physical process, replacing the traditional dualist views of programs as functional/structural or as symbolic/physical. This trinitarian view is found to be robust and helpful to solve typical issues of dualist views. Drawing comparisons with Simon’s view of the artifact as an interface, the author suggests that this (...) trinitarian view may characterize not only computational artifacts but also artifacts in general. One ambiguity is however noticed on the denotation of what Turner actually calls the “physical process.”. (shrink)

The paper is an investigation into the concept of actuality from the standpoint of the philosophy of language. It is argued that expressions such as 'actually' and 'in fact' are not indexicals like 'here' and 'now'; when e.g. 'Snow is actually white' is uttered in a world, what proposition is conveyed does not depend on the world. Nor are such expressions ambiguous. The paper makes a suggestion about the role that 'actually' and its cognates do play. It is also argued (...) that the sentence ⌜Actually S ⌝ expresses a necessary truth only if S itself expresses one. In order to capture the necessitation of the proposition expressed in ⌜Actually S ⌝, it is not sufficient to prefix the word 'necessarily'. (shrink)

Systems biology is today such a widespread discipline that it becomes difficult to propose a clear definition of what it really is. For some, it remains restricted to the genomic field. For many, it designates the integrated approach or the corpus of computational methods employed to handle the vast amount of biological or medical data and investigate the complexity of the living. Although defining systems biology might be difficult, on the other hand its purpose is clear: systems biology, with its (...) emerging subfields systems medicine and systems pharmacology, clearly aims at making sense of complex observations/experimental and clinical datasets to improve our understanding of diseases and their treatments without putting aside the context in which they appear and develop. In this short review, we aim to specifically focus on these new subfields with the new theoretical tools and approaches that were developed in the context of cancer. Systems pharmacology and medicine now give hope for major improvements in cancer therapy, making personalized medicine closer to reality. As we will see, the current challenge is to be able to improve the clinical practice according to the paradigm shift of systems sciences. (shrink)

In this Chapter, Maria Kronfeldner discusses whether psychological essentialism is a necessary part of dehumanization. This involves different elements of essentialism, and a narrow and a broad way of conceptualizing psychological essentialism, the first akin to natural kind thinking, the second based on entitativity. She first presents authors that have connected essentialism with dehumanization. She then introduces the error theory of psychological essentialism regarding the category of the human, and distinguishes different elements of psychological essentialism. On that basis, Kronfeldner (...) connects historical, socio-psychological, and philosophical insights in order to show that although essentialism can act as a catalyst for dehumanization, it is not necessary for it. Examples relate to dehumanization in the context of colonialism and evolutionary thinking, to the history of dehumanizing women from Aristotle to 19th-century craniology, and to contemporary self-dehumanization and ‘lesser mind’ attribution.

Silence is reserved for what cannot be verbally expressed. The well-known Wittgensteinian quote summarizes an established understanding of the relationship between language and silence: because language is not enough to account for reality and thinking, it must be transcended by other means of expression, like music or silence. But what if the opposite is the case and silence is not the extension but the precondition of language, the ultimate source of meaning? This paper explores how this is the phenomenological and (...) Derridean philosophical framework of Coetzee’s novels, a literary universe created from the will to signify and build singular meanings. (shrink)

Conceptions of evil have changed dramatically over time, and though humans continue to commit acts of cruelty against one another, today we possess a clearer, more moral way of analyzing them. In _Narrating Evil_, María Pía Lara explores what has changed in our understanding of evil, why the transformation matters, and how we can learn from this specific historical development. Drawing on Immanuel Kant's and Hannah Arendt's ideas about reflective judgment, Lara argues that narrative plays a key role in helping (...) societies acknowledge their pasts. Particular stories haunt our consciousness and lead to a kind of examination and dialogue that shape notions of morality. A powerful description of a crime can act as a filter, helping us to draw conclusions about what constitutes a moral wrong, and public debates over these narratives allow us to construct a more accurate picture of historical truth, leading to a better understanding of why such actions are possible. In building her argument, Lara considers Greek tragedies, Shakespeare's depictions of evil, Joseph Conrad's literary metaphors, and movies that portray human cruelty. Turning to such philosophers and writers as Jürgen Habermas, Walter Benjamin, Primo Levi, Giorgio Agamben, and Ariel Dorfman, Lara defines a reflexive relationship between an event, the narrative of the event, and the public reception of the narrative, and she proves that the stories of perpetrators and sufferers are always intertwined. The process of disclosure, debate, and the public fashioning of collective judgment are vital methods through which we make sense not only of new forms of cruelty but of past crimes as well. _Narrating Evil_ describes the steps of this process and why they are a crucial part of our attempt to build a different, more just world.

Important empirically informed proposals of virtue cultivation invoke techniques of goal pursuit. This paper argues that these techniques are effective in changing behavior due to the attention narrowing they bring about, and further show that such attention narrowing can threaten the appropriate exercise of phronetic-related capacities. When these phronetic-related capacities are threatened, two derivative problems arise: (1) One can end up acting in morally inappropriate ways, and (2) Even in cases where one performs the morally appropriate action, one nonetheless can (...) fail to notice and appreciate features of moral value. In light of these concerns, such techniques of goal pursuit – at least, by themselves – serve the most good for those who are merely trying to avoid vice, rather than cultivate virtue. And so, I suggest that such accounts of virtue cultivation are incomplete. I then go on to argue that these undesirable effects of attention narrowing brought about by these goal pursuit techniques may be ameliorated by also engaging in certain indirect modifications of cognition, particularly those which broaden attention. The suggestion, then, is that attention narrowing techniques of goal pursuit, along with attention broadening modifications, might best facilitate virtue cultivation when employed together. While the particulars of how we might best go about this are currently unclear, this paper ends by looking at empirical research on Open Monitoring Meditation as providing a hopeful option that might be further investigated.

Maria Kronfeldner’s Preface and Introduction to the Routledge Handbook of Dehumanization maps the landscape of dehumanization studies. She starts with a brief portrayal of the history of the field. The systematically minded sections that follow guide the reader through the resulting rugged landscape represented in the Handbook’s contributions. Different realizations, levels, forms, and ontological contrasts of dehumanization are distinguished, followed by remarks on the variety of targets of dehumanization. A discussion on valence and emotional aspects is added. Causes, functions, (...) and consequences of dehumanization, and the prospects for reducing or undoing it, are introduced. The systematic overview closes with a discussion of some important theoretical complexities that arise in studying dehumanization. After these systematic sections, the scholarly work on dehumanization gets situated in the broader intellectual landscape of debates about the ‘human’ in the humanities and social sciences. The Introduction ends with some notes on scope, limitations, and intended readership of the Handbook. (shrink)

Postmodern political critiques speak of the death of ideology, the end of history, and the postsecular return of religious attitudes, yet radical conservative theorists such as Mark Lilla argue religion and politics are inextricably intertwined. Returning much-needed uncertainty to debates over the political while revitalizing the very terms in which they are defined, María Pía Lara explores the ambiguity of secularization and the theoretical potential of a structural break between politics and religion. For Lara, secularization means three things: the translation (...) of religious semantics into politics; a transformation of religious notions into political ideas; and the reoccupation of a space left void by changing political actors that gives rise to new conceptions of political interaction. Conceptual innovation redefines politics as a horizontal relationship between governments and the governed and better enables societies (and individual political actors) to articulate meaning through action--that is, through the emergence of new concepts. These actions, Lara proves, radically transform our understanding of politics and the role of political agents and are further enhanced by challenging the structural dependence of politics on religious phenomena.

The liar and kindred paradoxes show that we can derive contradictions if our language possesses sentences lending themselves to paradox and we reason classically from schema about truth: Sis true iffp, where the letter p is to be replaced with a sentence and the letter S with a name of that sentence. This article presents a theory of truth that keeps at the expense of classical logic. The theory is couched in a language that possesses paradoxical sentences. It incorporates all (...) the instances of the analogue of for that language and also includes other platitudes about truth. The theory avoids contradiction because its logical framework is an appropriately constructed nonclassical propositional logic. The logic and the theory are different from others that have been proposed for keeping, and the methods used in the main proofs are novel. (shrink)

The paradoxes about truth are the subject of extensive research. Developing an original approach, this book argues that we should diverge from classical logic and presents a number of formal theories of truth. Also included is a beginner-friendly introduction to semantic paradoxes, and a discussion of alternative non-classical theories.

The liar and kindred paradoxes show that we can derive contradictions when we reason in accordance with classical logic from the schema (T) about truth: S is true iff p, where ‘p’ is to be replaced with a sentence and ‘S’ with a name of that sentence. The paper presents two arguments to the effect that the blame lies not with (T) but with classical logic. The arguments derive contradictions using classical logic, but instead of appealing to (T), they invoke (...) semantic claims that seem even harder to reject. The first argument relies on two standard semantic principles that are not disquotational and on the claim that if there is such a thing as the property of being true, then ‘true’ expresses that property. The second argument relies on a schema about meaning: S means that p, where ‘S’ and ‘p’ are to be replaced as before. (shrink)

Take a formula of first-order logic which is a logical consequence of some other formulae according to model theory, and in all those formulae replace schematic letters with English expressions. Is the argument resulting from the replacement valid in the sense that the premisses could not have been true without the conclusion also being true? Can we reason from the model-theoretic concept of logical consequence to the modal concept of validity? Yes, if the model theory is the standard one for (...) sentential logic; no, if it is the standard one for the predicate calculus; and yes, if it is a certain model theory for free logic. These conclusions rely inter alia on some assumptions about possible worlds, which are mapped into the models of model theory. Plural quantification is used in the last section, while part of the reasoning is relegated to an appendix that includes a proof of completeness for a version of free logic. (shrink)

La distinction qu’Aristote propose de la connaissance pratique et de la connaissance théorique semble laisser le statut de la technique problématique : présentée comme une étape vers la science en Métaphysique A 1, la technique est rapprochée de la prudence en Éthique à Nicomaque VI 1, en ce qu’elles relèvent toutes deux de la même « raison délibérative ». Cette indétermination semble légitimer la critique célèbre adressée par Kant à la distinction aristotélicienne, ainsi que la conclusion radicale qu’il en tire (...) de rapatrier l’ensemble de la technique et des maximes de la prudence dans le domaine de la connaissance théorique. Le commentaire aristotélicien lui-même reste divisé sur cette question. Dans cet article, nous souhaitons proposer une interprétation nouvelle de la place qu’assigne Aristote à la technique dans le domaine du savoir, et notamment de son autonomie vis-à-vis des sciences théoriques. Cette interprétation se fonde sur l’analyse par Aristote de la délibération pratique comme d’une forme de recherche (ζήτησις), qui s’oppose fondamentalement à l’ἐπιστήμη comme savoir constitué et achevé dans sa présentation déductive. La technique apparaît alors comme le savoir positif qui permet de guider la délibération, et qui a donc trait aux méthodes. L’intérêt de cette lecture est de suggérer l’existence d’un lien profond entre la technique et la logique de l’ Organon, qui pointe vers notre concept moderne de « procédure », dont le rôle est central dans la théorie moderne de la calculabilité et en informatique.

Large sets of elements interacting locally and producing specific architectures reliably form a category that transcends the usual dividing line between biological and engineered systems. We propose to call them morphogenetically architected complex systems. While taking the emergence of properties seriously, the notion of MACS enables at the same time the design of operational means that allow controlling and even, paradoxically, programming this emergence. To demonstrate our claim, we first show that among all the self-organized systems studied in the field (...) of Artificial Life, the specificity of MACS essentially lies in the close relation between their emergent properties and functional properties. Second, we argue that to be a MACS a system does not need to display more than weak emergent properties. Third, since the notion of weak emergence is based on the possibility of simulation, whether computational or mechanistic via machines, we see MACS as good candidates to help design artificial self-architected systems but also harness and redesign living ones.

Philosophy in the 20th century witnessed a schism between so called ‘analytic’ and ‘continental’ schools of philosophy. One of the aims of the IJPS from its inception was to provide a space for articles attempting to overcome, or at least foreshorten, that divide. This paper critically examines the various understandings of the divide and takes a quick glance at some of the attempts to bridge it.

What is it about relativism that justifies, or at least explains, its continued appeal in the face of relentless attacks through the history of philosophy? This paper explores a new answer to this old question, casting the response in metaphilosophical terms. § i introduces the problem. § ii argues that one part of the answer is that some of the well-known defences of relativism take it to be a philosophical stance—that is, a broad perspective or orientation with normative consequences—rather than (...) a doctrine or a thesis. § iii draws attention to an assumption, not always explicitly stated by its proponents, that the relativist stance leads to the cultivation of some key intellectual virtues. Open-mindedness, tolerance, intellectual humility, and curiosity are examples of the intellectual virtues that relativism can foster. § iv argues that the defence of relativism on the basis of the virtues that are assumed to follow from it, at best, is only partially successful. Moreover, there is a range of epistemic vices, resulting from the stance, that undercuts the virtue-based defence presented in § iii. (shrink)

Abstract This paper discusses some recent work on the notion of possibility in Wittgenstein's Tractatus assessed by means of an interpretation of the notion put forward in Cerezo 2005. It argues that the proper way to understand the notion of possibility in the Tractatus must pay equal attention both to the picture theory and the truth-functions theory. From this perspective, through an examination of Peach's proposal (2007) it shows that the role played by the notion of logical space in the (...) determination of sense needs to be emphasized. In addition, the paper considers some consequences of the Tractarian notion of possibility, namely, the strong contingency of the world that it involves, which is revealed by the thinkability of logical space as empty envisaged by Wittgenstein in T 2.013, and also discusses the recent debate between Reinhardt (2005) and Geach (2006) on this issue.

As it emerged from philosophical analyses and cognitive research, most concepts exhibit typicality effects, and resist to the efforts of defining them in terms of necessary and sufficient conditions. This holds also in the case of many medical concepts. This is a problem for the design of computer science ontologies, since knowledge representation formalisms commonly adopted in this field do not allow for the representation of concepts in terms of typical traits. However, the need of representing concepts in terms of (...) typical traits concerns almost every domain of real world knowledge, including medical domains. In particular, in this article we take into account the domain of mental disorders, starting from the DSM-5 descriptions of some specific mental disorders. On this respect, we favor a hybrid approach to the representation of psychiatric concepts, in which ontology oriented formalisms are combined to a geometric representation of knowledge based on conceptual spaces.
