Existe uma aparente contradição entre a negação kantiana do direito de resistência expressa na filosofia do direito e a sua apologia à Revolução Francesa abordada na história filosófica. No entanto, esta contradição se dissolve tão logo se compreende que Kant considerou que a Revolução Francesa não constitui precisamente uma revolução, uma vez que isto implicaria que o povo retornasse ao estado de natureza com relação ao soberano deposto, mas uma reforma constitucional empreendida involuntariamente pelo próprio rei Luis XVI que transferiu (...) a soberania aos representantes do povo ao convocar os Estados Gerais, os quais não tinham a obrigação de restituí-la ao soberano anterior, em lugar disso, preferiram se declarar em Assembleia Nacional e elaborar a constituição republicana, a única conforme a vontade unificada do povo.

Throughout the biological and biomedical sciences there is a growing need for, prescriptive ‘minimum information’ (MI) checklists specifying the key information to include when reporting experimental results are beginning to find favor with experimentalists, analysts, publishers and funders alike. Such checklists aim to ensure that methods, data, analyses and results are described to a level sufficient to support the unambiguous interpretation, sophisticated search, reanalysis and experimental corroboration and reuse of data sets, facilitating the extraction of maximum value from data sets (...) them. However, such ‘minimum information’ MI checklists are usually developed independently by groups working within representatives of particular biologically- or technologically-delineated domains. Consequently, an overview of the full range of checklists can be difficult to establish without intensive searching, and even tracking thetheir individual evolution of single checklists may be a non-trivial exercise. Checklists are also inevitably partially redundant when measured one against another, and where they overlap is far from straightforward. Furthermore, conflicts in scope and arbitrary decisions on wording and sub-structuring make integration difficult. This presents inhibit their use in combination. Overall, these issues present significant difficulties for the users of checklists, especially those in areas such as systems biology, who routinely combine information from multiple biological domains and technology platforms. To address all of the above, we present MIBBI (Minimum Information for Biological and Biomedical Investigations); a web-based communal resource for such checklists, designed to act as a ‘one-stop shop’ for those exploring the range of extant checklist projects, and to foster collaborative, integrative development and ultimately promote gradual integration of checklists.

Physiological responses in futsal have not been studied together with temporal information about the players’ stay on the court. The aim of this study was to compare heart rate and blood lactate concentration responses between 1-H and 2-H considering the time of permanency of the players on the court at each substitution in a futsal match. HR was recorded during entire match and [La−] was analyzed after each substitution of seven players. %HRmean and [La−] mean did not differ between 1-H (...) and 2-H. Time in intensity zones of 50–100 %HRmax differed only in 60–70 %HRmax. HR coefficient of variation throughout the match was low and among the four outfield players on the court. Substitutions, time of permanence on the court, ratio between time in- and out-ratio on the court also were similar between 1-H and 2-H. Balancing the number of substitutions, and the In:Outcourt ratio of players in both halves of the match, playing lower time at 1-H, ~8 min for each participation in the match, made it possible to maintain intensity of the match in 2-H similar to the 1H. These results are a good guidance to coaches and for application in future studies. (shrink)

The genetic code appeared on Earth with the first cells. The codes of cultural evolution arrived almost four billion years later. These are the only codes that are recognized by modern biology. In this book, however, Marcello Barbieri explains that there are many more organic codes in nature, and their appearance not only took place throughout the history of life but marked the major steps of that history. A code establishes a correspondence between two independent 'worlds', and the codemaker (...) is a third party between those 'worlds'. Therefore the cell can be thought of as a trinity of genotype, phenotype and ribotype. The ancestral ribotypes were the agents which gave rise to the first cells. The book goes on to explain how organic codes and organic memories can be used to shed new light on the problems encountered in cell signalling, epigenesis, embryonic development, and the evolution of language.

Biosemiotics is the synthesis of biology and semiotics, and its main purpose is to show that semiosis is a fundamental component of life, i.e., that signs and meaning exist in all living systems. This idea started circulating in the 1960s and was proposed independently from enquires taking place at both ends of the Scala Naturae. At the molecular end it was expressed by Howard Pattee’s analysis of the genetic code, whereas at the human end it took the form of Thomas (...) Sebeok’s investigation into the biological roots of culture. Other proposals appeared in the years that followed and gave origin to different theoretical frameworks, or different schools, of biosemiotics. They are: (1) the physical biosemiotics of Howard Pattee and its extension in Darwinian biosemiotics by Howard Pattee and by Terrence Deacon, (2) the zoosemiotics proposed by Thomas Sebeok and its extension in sign biosemiotics developed by Thomas Sebeok and by Jesper Hoffmeyer, (3) the code biosemiotics of Marcello Barbieri and (4) the hermeneutic biosemiotics of Anton Markoš. The differences that exist between the schools are a consequence of their different models of semiosis, but that is only the tip of the iceberg. In reality they go much deeper and concern the very nature of the new discipline. Is biosemiotics only a new way of looking at the known facts of biology or does it predict new facts? Does biosemiotics consist of testable hypotheses? Does it add anything to the history of life and to our understanding of evolution? These are the major issues of the young discipline, and the purpose of the present paper is to illustrate them by describing the origin and the historical development of its main schools. (shrink)

Who is to be included in a political community and on what terms? William A. Barbieri Jr. seeks answers to these questions in this exploration of the controversial concept of citizenship rights—a concept directly related to the nature of democracy, equality, and cultural identity. Through an examination of the case of Germany’s settled “guestworkers” and their families, _Ethics of Citizenship_ investigates the pressing problem of political membership in a world marked by increased migration, rising nationalist sentiment, and the ongoing (...) reorganization of states through both peaceful and violent means. Although some of Germany’s foreign workers have gradually attained a degree of social and economic legitimacy, Barbieri explains how they remain effectively excluded from true German citizenship. Describing how this exclusion has occurred and assessing current attitudes toward political membership in Germany, he argues for a just and democratic policy toward the tax-paying, migrant worker minority, one that would combine the extension of the individual rights of citizenship with the establishment of certain group rights. Through a dissection of ongoing public “membership debates” over issues such as suffrage, dual citizenship, and immigration and refugee policy, Barbieri identifies a range of competing responses to the question of who “belongs” in Germany. After critiquing these views, he proposes an alternative ethic of membership rooted in an account of domination and human rights that seeks to balance individual and group rights within the context of a commitment to democracy and equal citizenship. Indispensable for scholars of German studies, _Ethics of Citizenship_ also raises questions that will attract moral philosophers, constitutional scholars, and those interested in the continuing, global problems associated with migration.

Thomas Sebeok and Noam Chomsky are the acknowledged founding fathers of two research fields which are known respectively as Biosemiotics and Biolinguistics and which have been developed in parallel during the past 50 years. Both fields claim that language has biological roots and must be studied as a natural phenomenon, thus bringing to an end the old divide between nature and culture. In addition to this common goal, there are many other important similarities between them. Their definitions of language, for (...) example, have much in common, despite the use of different terminologies. They both regard language as a faculty, or a modelling system, that appeared rapidly in the history of life and probably evolved as an exaptation from previous animal systems. Both accept that the fundamental characteristic of language is recursion, the ability to generate an unlimited number of structures from a finite set of elements (the property of ‘discrete infinity’). Both accept that human beings are born with a predisposition to acquire language in a few years and without apparent efforts (the innate component of language). In addition to similarities, however, there are also substantial differences between the two fields, and it is an historical fact that Sebeok and Chomsky made no attempt at resolving them. Biosemiotics and Biolinguistics have become two separate disciplines, and yet in the case of language they are studying the same phenomenon, so it should be possible to bring them together. Here it is shown that this is indeed the case. A convergence of the two fields does require a few basic readjustments in each of them, but leads to a unified framework that keeps the best of both disciplines and is in agreement with the experimental evidence. What is particularly important is that such a framework suggests immediately a new approach to the origin of language. More precisely, it suggests that the brain wiring processes that take place in all phases of human ontogenesis (embryonic, foetal, infant and child development) are based on organic codes, and it is the step-by-step appearance of these brain-wiring codes, in a condition that is referred to as cerebra bifida, that holds the key to the origin of language.

The existence of different types of semiosis has been recognized, so far, in two ways. It has been pointed out that different semiotic features exist in different taxa and this has led to the distinction between zoosemiosis, phytosemiosis, mycosemiosis, bacterial semiosis and the like. Another type of diversity is due to the existence of different types of signs and has led to the distinction between iconic, indexical and symbolic semiosis. In all these cases, however, semiosis has been defined by the (...) Peirce model, i.e., by the idea that the basic structure is a triad of ‘sign, object and interpretant’, and that interpretation is an essential component of semiosis. This model is undoubtedly applicable to animals, since it was precisely the discovery that animals are capable of interpretation that allowed Thomas Sebeok to conclude that they are also capable of semiosis. Unfortunately, however, it is not clear how far the Peirce model can be extended beyond the animal kingdom, and we already know that we cannot apply it to the cell. The rules of the genetic code have been virtually the same in all living systems and in all environments ever since the origin of life, which clearly shows that they do not depend on interpretation. Luckily, it has been pointed out that semiosis is not necessarily based on interpretation and can be defined exclusively in terms of coding. According to the ‘code model’, a semiotic system is made of signs, meanings and coding rules, all produced by the same codemaker, and in this form it is immediately applicable to the cell. The code model, furthermore, allows us to recognize the existence of many organic codes in living systems, and to divide them into two main types that here are referred to as manufacturing semiosis and signalling semiosis. The genetic code and the splicing codes, for example, take part in processes that actually manufacture biological objects, whereas signal transduction codes and compartment codes organize existing objects into functioning supramolecular structures. The organic codes of single cells appeared in the first three billion years of the history of life and were involved either in manufacturing semiosis or in signalling semiosis. With the origin of animals, however, a third type of semiosis came into being, a type that can be referred to as interpretive semiosis because it became closely involved with interpretation. We realize in this way that the contribution of semiosis to life was far greater than that predicted by the Peirce model, where semiosis is always a means of interpreting the world. Life is essentially about three things: (1) it is about manufacturing objects, (2) it is about organizing objects into functioning systems, and (3) it is about interpreting the world. The idea that these are all semiotic processes, tells us that life depends on semiosis much more deeply and extensively than we thought. We realize in this way that there are three distinct types of semiosis in Nature, and that they gave very different contributions to the origin and the evolution of life. (shrink)

Systems Biology and the Modern Synthesis are recent versions of two classical biological paradigms that are known as structuralism and functionalism, or internalism and externalism. According to functionalism (or externalism), living matter is a fundamentally passive entity that owes its organization to external forces (functions that shape organs) or to an external organizing agent (natural selection). Structuralism (or internalism), is the view that living matter is an intrinsically active entity that is capable of organizing itself from within, with purely internal (...) processes that are based on mathematical principles and physical laws. At the molecular level, the basic mechanism of the Modern Synthesis is molecular copying, the process that leads in the short run to heredity and in the long run to natural selection. The basic mechanism of Systems Biology, instead, is self-assembly, the process by which many supramolecular structures are formed by the spontaneous aggregation of their components. In addition to molecular copying and self-assembly, however, molecular biology has uncovered also a third great mechanism at the heart of life. The existence of the genetic code and of many other organic codes in Nature tells us that molecular coding is a biological reality and we need therefore a framework that accounts for it. This framework is Code biology, the study of the codes of life, a new field of research that brings to light an entirely new dimension of the living world and gives us a completely new understanding of the origin and the evolution of life.

Today there are two major theoretical frameworks in biology. One is the ‘chemical paradigm’, the idea that life is an extremely complex form of chemistry. The other is the ‘information paradigm’, the view that life is not just ‘chemistry’ but ‘chemistry-plus-information’. This implies the existence of a fundamental difference between information and chemistry, a conclusion that is strongly supported by the fact that information and information-based-processes like heredity and natural selection simply do not exist in the world of chemistry. Against (...) this conclusion, the supporters of the chemical paradigm have pointed out that information processes are no different from chemical processes because they are both described by the same physical quantities. They may appear different, but this is only because they take place in extremely complex systems. According to the chemical paradigm, in other words, biological information is but a shortcut term that we use to avoid long descriptions of countless chemical reactions. It is intuitively appealing, but it does not represent a new ontological entity. It is merely a derived construct, a linguistic metaphor. The supporters of the information paradigm insist that information is a real and fundamental entity of Nature, but have not been able to prove this point. The result is that the chemical view has not been abandoned and the two paradigms are both coexisting today. Here it is shown that an alternative does exist and is a third theoretical framework that is referred to as the ‘code paradigm’. The key point is that we need to introduce in biology not only the concept of information but also that of meaning because any code is based on meaning and a genetic code does exist in every cell. The third paradigm is the view that organic information and organic meaning exist in every living system because they are the inevitable results of the processes of copying and coding that produce genes and proteins. Their true nature has eluded us for a long time because they are nominable entities, i.e., objective and reproducible observables that can be described only by naming their components in their natural order. They have also eluded us because nominable entities exist only in artifacts and biologists have not yet come to terms with the idea that life is artifact making. This is the idea that life arose from matter and yet it is fundamentally different from it because inanimate matter is made of spontaneous structures whereas life is made of manufactured objects. It will be shown, furthermore, that the existence of information and meaning in living systems is documented by the standard procedures of science. We do not have to abandon the scientific method in order to introduce meaning in biology. All we need is a science that becomes fully aware of the existence of organic codes in Nature. (shrink)

Biosemiotics asserts the idea that semiosis is fundamental to life, and that all living creatures are therefore semiotic systems. The idea itself is strongly supportedby the evidence of the genetic code — but thus far it has made little impact in the scientific world, and is largely regarded as the basis for a philosophy of meaning, rather than a basis for a science of meaning. This is regrettable, but perhaps understandable from the scientists’ point of view. Scientists know that the (...) cell is the necessary unit of all life. I will argue here, then, that Biosemiotics can become a science only if it can prove that the cell is, in fact, a semiotic system — i.e., that semiosis exists at the cellular level. To do this, we first need to define what is semiosis, so that we can be explicit about what exactly constitutes a semiotic system. So far, we have had two main answers to this question. One is the model proposed by Saussure, who defined a semiotic system as a duality of ‘signifier and signified’. The other is the model of Peirce, who pointed out that interpretation is an essential component of semiosis and defined a semiotic system as a triad of ‘sign, object and interpretant’. After the discovery of the genetic code, each of these two models have been applied to biology and have given rise to two distinct schools of biosemiotics. One is the school of Marcel Florkin, which is based on the model of Saussure, and the other is the school of Thomas Sebeok, which is based on the model of Peirce. Unfortunately, neither of them can be applied to the cell, and that is why most biologists continue to be skeptical about biosemiotics. There is however a third model of semiosis that is actually applicable to the cell. It is based on the theory that the cell is a trinity of genotype, phenotype and ribotype. Here, the ribotype is the ribonucleoprotein system of the cell and represents its ‘codemaker’, i.e., the seat of the genetic code. This model assumes that semiosis is defined by coding, not by interpretation, and is therefore referred to as the code model of semiosis. This paper is dedicated to illustrating this third model and, above all, to showing that the cell is a true semiotic system. (shrink)

The discovery of the genetic code has shown that the origin of life has also been the origin of semiosis, and the discovery of many other organic codes has indicated that organic semiosis has been the sole form of semiosis present on Earth in the first three thousand million years of evolution. With the origin of animals and the evolution of the brain, however, a new type of semiosis came into existence, a semiosis that is based on interpretation and is (...) commonly referred to as interpretive, or Peircean semiosis. This suggests that there are two distinct types of semiosis in Nature, one based on coding and one based on interpretation, and all the experimental evidence that we have does support this conclusion. Both in principle and in practice, therefore, there is no conflict between organic semiosis and Peircean semiosis, and yet they have been the object of a fierce controversy because it has been claimed that semiosis is always based on interpretation, even at the cellular level. Such a claim has recently been reproposed in a number of papers and it has become necessary therefore to reexamine it in the light of the proposed arguments. (shrink)

There are currently three major theories on the origin and evolution of the genetic code: the stereochemical theory, the coevolution theory, and the error-minimization theory. The first two assume that the genetic code originated respectively from chemical affinities and from metabolic relationships between codons and amino acids. The error-minimization theory maintains that in primitive systems the apparatus of protein synthesis was extremely prone to errors, and postulates that the genetic code evolved in order to minimize the deleterious effects of the (...) translation errors. This article describes a fourth theory which starts from the hypothesis that the ancestral genetic code was ambiguous and proposes that its evolution took place with a mechanism that systematically reduced its ambiguity and eventually removed it altogether. This proposal is distinct from the stereochemical and the coevolution theories because they do not contemplate any ambiguity in the genetic code, and it is distinct from the error-minimization theory because ambiguity-reduction is fundamentally different from error-minimization. The concept of ambiguity-reduction has been repeatedly mentioned in the scientific literature, but so far it has remained only an abstract possibility because no model has been proposed for its mechanism. Such a model is described in the present article and may be the first step in a new approach to the study of the evolution of the genetic code. (shrink)

Coding characteristics have been discovered not only in protein synthesis, but also in various other natural processes, thus showing that the genetic code is not an isolated case in the organic world. Other examples are the sequence codes, the adhesion code, the signal transduction codes, the splicing codes, the sugar code, the histone code, and probably more. These discoveries however have not had a significant impact because of the widespread belief that organic codes are not real but metaphorical entities. They (...) are supposed to lack arbitrariness and codemakers, the two qualifying features of real codes. Here it is shown that the arbitrariness issue can be solved on an experimental basis, while the codemaker issue is dependent on our theoretical description of the cell and can only be solved by a new concept. In order to appreciate the reality of the organic codes, in short, it is necessary to have not only a more critical evaluation of the experimental data but also a new theory of the living system.

Alternative agricultural systems, like organic and local agriculture, are becoming increasingly important in Europe to the detriment of conventional methods. As a matter of fact, sustainable agriculture, which started as a niche sector, has been able to conquer a significant share of the European agro-food market. Institutional promotion along with increasing consumer demand has allowed for the development of different agricultural models, from the farm to the fork, with an increasing focus on the ethical issues associated with the agro-food production (...) system. For instance, the organic agriculture agro-food chain is based on four principles, namely health, ecology, fairness and care with the goal of competing in the global agro-food market while respecting the environment, livestock, producers, and consumers. Within these themes, the seed market represents an extremely complex part of the whole picture. The present paper analyses the historical evolution of the seed sector by identifying the main issues related to sustainable agricultural systems and protection of biodiversity. It follows the identification of different seed markets based on different farm types. The two aspects are then discussed and matched in order to identify the main issues characterizing the sector. A review of possible solutions to those problems, taking into account their ethics, is also provided. (shrink)

Biosemiotics argues that “sign” and “meaning” are two essential concepts for the explanation of life. Peircean biosemiotics, founded by Tomas Sebeok from Peirce’s semiotics and Jacob von Uexkül’s studies on animal communication, today makes up the mainstream of this discipline. Marcello Barbieri has developed an alternative account of meaning in biology based on the concept of code. Barbieri rejects Peircean biosemiotics on the grounds that this discipline opens the door to nonscientific approaches to biology through its use of (...) the concept of “interpretation.” In this article, it is noted that Barbieri does not adequately distinguish among Peirce’s semiotics, Peircean biosemiotics, and “interpretation-based” biosemiotics. Two key arguments of Barbieri are criticized: his limited view of science and his rejection of “interpretation-based” biosemiotics. My argument is based on tools taken from a different approach: Robert Rosen’s relational biology. Instead of “signs” and “meanings,” the study begins in this case from the “components” and “functions” of the organism. Rosen pursues a new definition of a law of nature, introduces the anticipatory nature of organisms, and defines the living being as a system closed to efficient cause. It is shown that Code Biosemiotics and Peircean biosemiotics can share a common field of study. Additionally, some proposals are suggested to carry out a reading of Rosen’s biology as a biosemiotic theory. (shrink)

The New World of the Organic CodesThe genetic code appeared on Earth at the origin of life, and the codes of culture arrived almost 4 billion years later, at the end of life’s history. Today it is widely assumed that these are the only codes that exist in Nature, and if this were true we would have to conclude that codes are extraordinary exceptions because they appeared only at the beginning and at the end of evolution. In reality, various other (...) organic codes have been discovered in the past few decades.In 1975, the American biochemist Gordon Tomkins published a paper entitled The Metabolic Code. Biological symbolism and the origin of intercellular communication . That was the very first announcement of a new organic code after the discovery of the genetic code, but tragically Tomkins died that very year and his new world of organic symbolism remained unexplored. Some 10 years later, Edward Trifonov started a life-long campaign in favour .. (shrink)

It is shown that information and meaning can be defined by operative procedures, and that we need to recognize them as new types of natural entities. They are not quantities (neither fundamental nor derived) because they cannot be measured, and they are not qualities because they are not subjective features. Here it is proposed to call them nominable entities, i.e., entities which can be specified only by naming their components in their natural order.

One of the central methodological issues for contemporary practitioners of comparative ethics is how to conceptualize and relate to the "other" encountered in cross-cultural studies. A valuable resource for reflection on this problem is the work of the French historian and cultural theorist Michel de Certeau, whose diverse opus coheres around his notion of heterology--a "science of the other." In this article I explore perspectives on the cultural "other" emerging from Certeau's analyses of a series of "travel narratives" documenting the (...) European encounter with the peoples of the New World. Certeau's meditations on the metaphor of the voyage, the interplay of orality and literacy, the politics of ethnography, and the semiotics of the "return of the repressed" offer, I suggest, important insights for comparative ethicists.

Contemporary biological research has suggested that some host–microbiome multispecies systems (referred to as “holobionts”) can in certain circumstances evolve as unique biological individual, thus being a unit of selection in evolution. If this is so, then it is arguably the case that some biological adaptations have evolved at the level of the multispecies system, what we call hologenomic adaptations. However, no research has yet been devoted to investigating their nature, or how these adaptations can be distinguished from adaptations at the (...) species-level (genomic adaptations). In this paper, we cover this gap by investigating the nature of hologenomic adaptations. By drawing on the case of the evolution of sanguivory diet in vampire bats, we argue that a trait constitutes a hologenomic adaptation when its evolution can only be explained if the holobiont is considered the biological individual that manifests this adaptation, while the bacterial taxa that bear the trait are only opportunistic beneficiaries of it. We then use the philosophical notions of emergence and inter-identity to explain the nature of this form of individuality and argue why it is special of holobionts. Overall, our paper illustrates how the use of philosophical concepts can illuminate scientific discussions, in the trend of what has recently been called metaphysics of biology. (shrink)
