Continuous culture techniques were developed in the early twentieth century to replace cumbersome studies of cell growth in batch cultures. In contrast to batch cultures, they constituted an open concept, as cells are forced to proliferate by adding new medium while cell suspension is constantly removed. During the 1940s and 1950s new devices have been designed—called “automatic syringe mechanism,” “turbidostat,” “chemostat,” “bactogen,” and “microbial auxanometer”—which allowed increasingly accurate quantitative measurements of bacterial growth. With these devices cell growth came under the (...) external control of the experimenters and thus accessible for developing a mathematical theory of growth kinetics—developed mainly by Jacques Monod, Aron Novick and Leo Szilard in the early 1950s and still in use today. The paper explores the development of continuous culture devices and claims that these devices are simulators for standard cells following specific requirements, in particular involving mathematical constraints in the design and setting of the devices as well as experiments. These requirements have led to contemporary designs of continuous culture techniques realizing a specific event-based flow algorithm able to simulate directed evolution and produce artificial cells and microorganisms. This current development is seen as an alternative approach to today’s synthetic biology. (shrink)

SUMMARYHistorians of historiography have recently adopted the language of ‘epistemic virtues’ to refer to character traits believed to be conducive to good historical scholarship. While ‘epistemic virtues’ is a modern philosophical concept, virtues such as ‘objectivity’, ‘meticulousness’ and ‘carefulness’ historically also served as actors' categories. Especially in the late nineteenth and early twentieth centuries, historians frequently used virtue language to describe what it took to be a ‘good’, ‘reliable’ or ‘professional’ scholar. Based on three European case studies—the German historian Georg (...) Waitz, his French pupil Gabriel Monod and the Belgian historian Henri Pirenne —this article argues that such virtues cannot neatly be classified as ‘epistemic’ ones. For what is characteristic about virtue language in historical scholarship around 1900 is an overlap or entanglement of epistemic, moral and political connotations. The virtues embodied by, or attributed to, Waitz, Monod and Pirenne were almost invariably aimed at epistemic, moral and political goods at once, though not always to the same degrees. Consequently, if ‘epistemic virtues’ is going to be a helpful category, it must not be interpreted in a strong sense, but in a weak one. (shrink)

Marquée à juste titre par le mouvement des Annales, l’historiographie française a intériorisé lidée qu’avant 1929 dominait ce que Henri Berr avait stigmatisé sous le nom d’ « histoire traditionnelle » : une histoire politique et individualiste ne tenant pas compte des déterminations collectives, sociales ou mentales. La fameuse Introduction aux études historiques de Langlois et Seignobos (1898) serait l’expression de ce «positivisme» qu’aurait initié Gabriel Monod, fondateur de la Revue historique en 1876. Cette vision traditionnelle de l’histoire (...) de la discipline est globalement remise en cause dans cet article qui montre que les années 1870-1930 sont au contraire un moment central dans l’historiographie tant au plan institutionnel qu’au plan intellectuel, qui nous intéresse surtout ici. C’est en effet dès cette époque que s’est cristallisée laspiration à faire de l’histoire une science sociale, ce qui se comprend aisément dès lors qu’on contextualise cette histoire et que l’on replace cette discipline dans l’ensemble du champ des sciences sociales. Les années 1890–1914 voient même se développer fortement une histoire économique et une histoire sociale. 1929 apparaît alors moins comme une révolution que comme une accélération dans une direction déjà marquée.

When viewed as the most comprehensive theory of collections, set theory leaves no room for classes. But the vocabulary of classes, it is argued, provides us with compact and, sometimes, irreplaceable formulations of largecardinal hypotheses that are prominent in much very important and very interesting work in set theory. Fortunately, George Boolos has persuasively argued that plural quantification over the universe of all sets need not commit us to classes. This paper suggests that we retain the vocabulary of classes, but (...) explain that what appears to be singular reference to classes is, in fact, covert plural reference to sets. (shrink)

This paper interprets the relation between sovereignty and guilt in Nietzsche's Genealogy. I argue that, contrary to received opinion, Nietzsche was not opposed to the moral concept of guilt. I analyse Nietzsche's account of the emergence of the guilty conscience out of a pre-moral bad conscience. Drawing attention to Nietzsche's references to many different forms of conscience and analogizing to his account of punishment, I propose that we distinguish between the enduring and the fluid elements of a ‘conscience’, defining the (...) enduring element as the practice of forming self-conceptions. I show that for Nietzsche, the moralization of the bad conscience results from mixing it with the material concepts of guilt and duty, a process effected by prehistoric religious institutions by way of the concept of god. This moralization furnishes a new conception of oneself as a responsible agent and holds the promise of sovereignty by giving us a freedom unknown to other creatures, but at the price of our becoming subject to moral guilt. According to Nietzsche, however, the very forces that made it possible have spoiled this promise and, under the pressures of the ascetic ideal, a harmful notion of responsibility understood in terms of sin now dominates our lives. Thus, to fully realize our sovereignty, we must liberate ourselves from this sinful conscience. (shrink)

Groups are ubiquitous in our lives. But while some of them are highly structured and appear to support a shared intentionality and even a shared agency, others are much less cohesive and do not seem to demand much of their individual members. Queues, for example, seem to be, at a given time, nothing over and above some individuals as they exemplify a certain spatial arrangement. Indeed, the main aim of this paper is to develop the more general thought that at (...) a given time, a group is nothing over and above some individual members as they exemplify a certain complex condition. The general conception of groups that emerges is able to accommodate a variety of constraints on a reasonable answer to the question of what are groups. (shrink)

Part I of Frege’s Grundgesetze is devoted to the “exposition [Darlegung]” of his formal system.

In this paper, I first explore Hegel’s own distinctions between various types of idealism, most of which he explicitly rejects. I discuss his notions of subjective, transcendental and absolute idealism and present the outlines of his criticisms of the first two as well as the motivation behind his commitment to a version of absolute idealism. In particular, I argue that the latter does not share the defining features of what is now commonly called ‘idealism’, as Hegel neither denies the existence (...) of an external world nor even holds that we can only somehow indirectly infer the truth of propositions about the external world from the structure of some given mental material. I give a basic account of what Hegel’s concept of ‘the absolute idea’ is about, which lies behind his absolute idealism. In this context, I maintain that it is crucial for our understanding of Hegel and of his potential relevance for contemporary metaphysics and epistemology that the absolute idea is precisely not a mental or ‘spiritual’ (geistig) entity. Rather, it amounts to a set of methodological assumptions designed to guarantee the overall intelligibility of what there is, regardless of its actual natural, social or more broadly normative structure.

Philosophers often explain what could be the case in terms of what is, in fact, the case at one possible world or another. They may differ in what they take possible worlds to be or in their gloss of what is for something to be the case at a possible world. Still, they stand united by the threat of paradox. A family of paradoxes akin to the set-theoretic antinomies seem to allow one to derive a contradiction from apparently plausible principles. (...) Some of them concern the interaction between propositions and worlds, and they appear to afford the means to map classes of propositions into propositions – or, likewise, classes of worlds into worlds – in a one-to-one fashion that leads to contradiction. Yet another family of paradoxes threaten the view that whatever could exist does, in fact, exist, which is in line with modal realism, for example. This article aims to survey and identify the source of each family of paradoxes as well as to outline some responses to them. (shrink)

We present two studies investigating the impact of causal perceptions and the moral emotions of anger, shame, and guilt on the justification of deviant workplace behavior. Study 1 tests our conceptual framework using a sample of undergraduate business students; Study 2 examines a population of practicing physicians. Results varied significantly between the two samples, suggesting that individual and contextual factors play an important role in shaping the perceptual and emotional processes by which individuals form reactions to undesirable affective workplace events. (...) Implications of these findings for the study of ethics, emotions, and attributions, as well as for promoting ethical behavior, are discussed. (shrink)

I present a puzzle for absolutely unrestricted quantification. One important advantage of absolutely unrestricted quantification is that it allows us to entertain perfectly general theories. Whereas most of our theories restrict attention to one or another parcel of reality, other theories are genuinely comprehensive taking absolutely all objects into their domain. The puzzle arises when we notice that absolutely unrestricted theories sometimes impose incompatible constraints on the size of the universe.

This essay argues for a model of pictorial representation which aims to explain the relationship between pictorial content and pictorial accuracy. Focusing on cases where pictures are intended to convey accurate information, the model distinguishes between two fundamental representational relations: on one hand, a picture expresses a content; on the other, it aims at a target scene. Such a picture is accurate when the content it expresses fits the target scene it aims at. In addition, the model follows the traditional (...) division of content into two aspects: singular content specifies the particular individuals which a picture is of, and attributive content specifies the properties and relations which the picture ascribes to those individuals. For a picture to be accurate, both aspects must be matched in the target. I call this the Three-Part Model because it distinguishes between the triad of factors, singular content, attributive content, and target, which together determine pictorial accuracy. Though previous work on depiction has not recognized the distinctive role played by target, I will argue that it is essential in order to make sense of accuracy judgements across a range of central cases.

The so-called Trolley Problem was first discussed by Philippa Foot in 1967 as a way to test moral intuitions regarding the doctrine of double effect, Kantian principles and utilitarianism. Ever since, a great number of philosophers and psychologists have come up with alternative scenarios to further test intuitions and the relevance of conventional moral doctrines. Given that physicians routinely face moral decisions regarding life and death, the Trolley Problem should be considered of great importance in medical ethics. In this article, (...) five “classic” trolley scenarios are discussed: the driver diverting the trolley, a bystander pulling a lever to divert the trolley, a fat man being thrown from a bridge to stop the trolley, a bystander pulling a lever to divert a trolley so that a fat man may be run over, and a bystander pulling a lever so that a fat man falls off from a bridge to stop the trolley. As these scenarios are discussed, relevant moral differences amongst them are addressed, and some of the applications in medical ethics are discussed. The article concludes that Trolley scenarios are not the ultimate criterion to make ethical decisions in difficult ethical challenges in medicine cases but they do serve as an initial intuitive guide.

While the word “democracy” has proliferated in social and political discourse in recent decades, I suggest that the liberal democracy of the past, connected as it is (especially in the West) to the market economy, is insufficient for the challenges facing the contemporary Latin American context. I assess and criticize democratic ideas in order to suggest that the way forward is radical democracy based on socio-economic and political justice. These, however, have to be articulated at a variety of levels, from (...) that of local and indigenous peoples to that of national and international relations. (shrink)

There has recently been much debate about the idea of levying a tax on particular transactions on international financial markets. Economists have argued about how much revenue such an international financial transaction tax would raise and they disagree about what effects it would have on trade volumes, financial stability, and overall growth. Politicians have argued about the feasibility of introducing such a tax internationally and they disagree on its adequacy as a policy response to the current financial and economic crisis. (...) This article contributes to the debate about international financial transaction taxation by bringing the perspective of political philosophy to bear on the politicians’ and economists’ arguments about policy. I shall outline a framework for thinking about justice in finance, and defend the idea of an international financial transaction tax as an instrument for making the international financial system more just.

Resumo: Lopes dos Santos, ao colocar o Tractatus Logico-Philosophicus no que denomina “tradição crítica”, mostra que Wittgenstein delimita o alcance da filosofia ao eliminar sua pretensão de ser um tipo de conhecimento que, como a ciência, possa formular proposições verificáveis sobre objetos. E Wittgenstein faz isso de modo distinto da crítica moderna à metafísica, pois elimina o sujeito do problema: não é preciso recorrer a faculdades subjetivas para fazer essa delimitação, mas apenas à linguagem na qual o pensamento se expressa. (...) Por outro lado, na perspectiva da “tradição lógica”, há na mesma obra uma identificação entre a essência do “logos” que pode enunciar algo verdadeiro sobre o ser e do próprio ser do qual se fala nesse discurso. Nosso objetivo é destacar este vínculo com a “tradição lógica” para defender que, para além de uma “virada linguística”, há no Tractatus uma espécie de “metafísica silenciosa” que coloca problemas tais como o do sujeito e o da “essência” do mundo em seu correto lugar após passá-los pelo crivo da crítica.

The history of the field of business ethics in the U.S. remains understudied and misunderstood. In this article I begin to remedy this oversight about the past, and I suggest how it can be beneficial in the present. Using both published and unpublished primary sources, I argue that the business ethics field emerged in the early twentieth century, against the backdrop of the establishment of business schools in major universities. I bring to light four important developments: business ethics lectures at (...) the University of California and Yale University, Leon Marshall’s curriculum at the College of Commerce of the University of Chicago, and the William A. Vawter Foundation on Business Ethics at Northwestern University. Then, I consider the payoffs of my historical account for business ethics theory, pedagogy, and practice. Specifically, I present four implications of my account under these headings: business ethics as a public problem; the place of ethics in business schools; historicizing business ethics; and historical self-knowledge.

La publication de l'Avenir dure longtemps, puis de nombreux autres inédits, ont donné à la pensée de Louis Althusser un regain d'actualité, indissociable d'une profonde modification de la lecture qui peut être faite de son oeuvre. On ne peut pas lire Althusser aujourd'hui comme on le faisait de son vivant. A leur (...) manière, chacun de ces exposés tournent ainsi autour d'une même question : qu'est-ce que lire Althusser aujourd'hui? (shrink)

Immortality is the indefinite continuation of a person’s existence, even after death. In common parlance, immortality is virtually indistinguishable from afterlife, but philosophically speaking, they are not identical. Afterlife is the continuation of existence after death, regardless of whether or not that continuation is indefinite. Immortality implies a never-ending existence, regardless of whether or not the body dies (as a matter of fact, some hypothetical medical technologies offer the prospect of a bodily immortality, but not an afterlife). Immortality has been (...) one of mankind’s major concerns, and even though it has been traditionally mainly confined to religious traditions, it is also important to philosophy. Although a wide variety of cultures have believed in some sort of immortality, such beliefs may be reduced to basically three non-exclusive models: (1) the survival of the astral body resembling the physical body; (2) the immortality of the immaterial soul (that is an incorporeal existence); (3) resurrection of the body (or re-embodiment, in case the resurrected person does not keep the same body as at the moment of death). This article examines philosophical arguments for and against the prospect of immortality. A substantial part of the discussion on immortality touches upon the fundamental question in the philosophy of mind: do souls exist? Dualists believe souls do exist and survive the death of the body; materialists believe mental activity is nothing but cerebral activity and thus death brings the total end of a person’s existence. However, some immortalists believe that, even if immortal souls do not exist, immortality may still be achieved through resurrection. Discussions on immortality are also intimately related to discussions of personal identity because any account of immortality must address how the dead person could be identical to the original person that once lived. Traditionally, philosophers have considered three main criteria for personal identity: the soul criterion , the body criterion and the psychological criterion. Although empirical science has little to offer here, the field of parapsychology has attempted to offer empirical evidence in favor of an afterlife. More recently, secular futurists envision technologies that may suspend death indefinitely (such as Strategies for Engineered Negligible Senescence, and mind uploading), thus offering a prospect for a sort of bodily immortality.

Can mathematics contribute to our understanding of physical phenomena? One way to try to answer this question is by getting involved in the recent philosophical dispute about the existence of mathematical explanations of physical phenomena. If there is such a thing, given the relation between explanation and understanding, we can say that there is an affirmative answer to our question. But what if we do not agree that mathematics can play an explanatory role in science? Can we still consider that (...) the above question can have an affirmative answer? My main aim here is to give an account that takes mathematics, in some of the cases discussed in the literature, as contributing to our understanding of physical phenomena despite not being explanatory.

This paper offers a new version of a historically influential, yet today unpopular, neglected, and on the whole insufficiently developed argument for socialism: socialism makes it possible for people to really act together. This idea of socialist action, combining the claims that there is a particularly valuable form of joint action and that socialism is about making such action possible, played an important role in the history of the labor movement, going back to the early Marx and running through various (...) strands of socialist thought. I shall argue that socialist action should be seen as central to the socialist project, its critique of capitalism, and the institutional alternatives envisaged by it. (shrink)

This paper presents a variable neighborhood descent algorithm for the service restoration problem (SRP) in electrical distribution systems. The restoration problem appears when a permanent fault occurs in the system. The fault must be localized and isolated from the rest of the system. As a consequence of the isolation, the downstream area is de-energized and requires restoration. The variable neighborhood descent algorithm features its ability to solve the SRP for radial distribution systems and introduces a strategy that helps to deal (...) with the system’s radiality. Tests are performed using a 53-node test system. The results show that the proposed algorithm can efficiently solve the SRP in a distribution system, and as a deterministic algorithm, the results can be used to help nondeterministic algorithms.

Employees play a critical role in materializing the company's purpose as they are the ones responsible for planning and executing all the organizational activities. Considering their vital role, we explored how employees, currently working full‐time from home, perceive their participation in the company's purpose. To do so, we performed online interviews with 23 employees from 14 companies. In addition to employees' perspectives, we collected textual data from the companies' websites where these employees were working, allowing us to compare both perspectives (...) and better understand employees' perspectives. Results revealed that employees do not directly recognize the organizational purpose concept and that the term purpose is barely found on the companies' websites. Therefore, we found that besides a problem of conceptual lack of clarity in the literature, organizational purpose is still on the way to being comprehended within companies. To help solve this problem, based on stakeholder theory, we discuss the meaning of organizational purpose and compare it to related concepts such as mission and vision. Finally, we offer managers orientation on how they should operationalize their companies' purpose and how they may externally communicate it online. (shrink)

Neste artigo buscamos investigar o papel da arte no pensamento e obra de Albert Camus. Para isso, avançamos em seus principais ensaios: O mito de Sísifo e O homem revoltado, na tentativa de sintetizar suas ideias acerca da criação absurda e da arte revoltada. Consideramos que a criação absurda, pensada n’O mito... sofrerá uma expansão explosiva no segundo ensaio do autor. Se, inicialmente, a arte para Camus devia expressar a fratura do homem e seu mundo, a consciência de nossa própria (...) absurdidade, a arte revoltada revela o movimento inicial de todas as subjetividades humanas: a estilização de um mundo sem sentido. Dessa forma, a criação artística deixa de ser unicamente uma escola de paciência, lucidez e multiplicação diante de uma experiência humana que carece de unidade e sentido, tornando-se a expressão mais proeminente dessa própria condição. O revoltado e o artista compartilham as mesmas exigências, éticas e estéticas, afinal, a própria revolta é, em parte, uma exigência estética. Desse modo, buscamos expor e elucidar os conceitos camusianos em torno da arte, absurda ou revoltada, e seus desdobramentos para uma ética estilizada. (shrink)
