A Richard Rorty se le considera hoy en día como uno de los filósofos más importantes de Norteamérica. Es posible que esta afirmación sea discutible; lo indiscutible es que, a juicio de los críticos, es el mejor escritor filosófico después de Bertrand Russell….

Los cimientos de una sociedad racional en Horkheimer parten de la premisa de hacer de la filosofía social una opción por la Teoría Crítica. Por ello [1] se desarrolla una interpretación dialéctica de lo social entre la filosofía y las teorías de las ciencias sociales, desde la categoría del materialismo interdisciplinario. [2] Caracterizar una época en estado de indigencia inicia definiendo la Ilustración como un proceso de desencantamiento del mundo que reduce la realidad humana en el signo del dominio . (...) El curso liberador de la Ilustración fue viciado desde el principio y terminó siendo un proceso de alienación y de cosificación. [3] Por tanto, se ponen en escena los sentimientos morales de la compasión y la solidaridad política para abordar una nueva perspectiva ética que define un imperativo existencial capaz de ver la miseria humana y la búsqueda de la felicidad, con el propósito de superar las condiciones y realidades de esta época en estado de indigencia.

La crítica horkheimeriana a la Ilustración muestra el proceso mediante el cual se desencadena la desmitificación del mundo por vía de un "acto de dominio" de la razón. Allí, el hombre perdió para la razón su posibilidad de autocrítica, haciendo que esta deviniera en razón instrumental. Desde sus comienzos, la Ilustración, en calidad de mito, mutiló la razón y, por encima de la búsqueda de la verdad -verdad teórica y verdad moral-, aconteció una "renuncia al sentido" donde el sueño de (...) la racionalidad ilustrada quedó reducido a la "instrumentalización". Esta dialéctica no solo devela la crisis irreversible de la razón, sino que deja vigente, en la discusión de la teoría crítica, la idea de una "patología social de la razón", a partir de la cual puede proponerse la reivindicación de un "horizonte normativo"; dejando entrever en el escenario de la discusión ética la falta de racionalidad de las sociedades. Horkheimerian's critique of the Enlightenment, shows the process whereby the demystification of the world is triggered by way of an "an act of sovereignty" of reason. There the man lost for reason his possibility of self-criticism, causing it to be in instrumental reason. Since its inception, the Enlightenment, as myth, mutilated reason, over the pursuit of truth -theoretical truth and moral truth-, there was a renounce to sense. The dream of Enlightenment rationality was reduced to the 'instrumentalization'. This dialectic not only reveals the irreversible crisis of reason, but leaves in place, in the discussion of critical theory, the idea of the 'social pathology of reason', from which a "normative horizon" can be proposed, hinting at the scene of the ethical discussion the lack of rationality of societies.

En los últimos 20 años el debate entre los Factores Comunes y los Tratamientos con Apoyo Empírico (TAE) ha sido uno de los más relevantes para la práctica clínica. El enfoque TAE con origen en la investigación sobre fármacos (Medicina Basada en la Evidencia), promueve el uso de técnicas específicas y protocolos de tratamiento. Los Factores Comunes, por el contrario, señalan la validez de múltiples psicoterapias, la cual estaría basada en dimensiones comunes a todo tratamiento, y no tanto en el (...) uso de técnicas específicas. El proceder médico y farmacológico encaja razonablemente dentro de un marco de acción instrumental, en el que el acto sanitario se ejerce a fin de modificar ciertos parámetros fisiológico-anatómicos. Pero la psicoterapia es mejor entendida como una relación entre sujetos, ya que el paciente, el objeto de la acción terapéutica, es también un sujeto, y no un parámetro. Por ello los protocolos como secuencias prefijadas de acciones del terapeuta (ideal para la investigación por su replicabilidad y pertinencia metodológica), implican una suerte de eliminación del sujeto. Cabe entonces entender el sentido de los protocolos de tratamiento como marcos de sentido, de problemas pertinentes, de soluciones indicadas. Como una forma de conocimiento flexible sobre el problema y su funcionamiento y manejo. (shrink)

Logistics services involve a wide range of transport operations between distributors and clients. Currently, the large number of intermediaries are a challenge for this sector, as it makes all the processes more complicated. To face that problem, we propose a system that uses smart contracts to remove intermediaries and speed up logistics activities. Our new model combines smart contracts and a multi-agent system in a single platform to improve the current logistics system by increasing organization, security and getting rid of (...) several human intermediaries to automate its processes, making distribution times significantly faster. Also, with this kind of approach, it is possible to apply penalties to parties that do not comply with the terms of using this platform. (shrink)

The present investigation aims to elucidate the presence of myth in the work of Eduardo Nicol. This inquiry of course, is something not thought about, since the author in question from the beginning of his philosophy has recognized that the path of thought is beyond myth, that is, it is nuanced by reason and by conceptual rigor. In other words, for him philosophy is about what is phenomenologically accessible and about what is rationally intelligible. Precisely for this reason, one of (...) the names with which Nicol's philosophy is known is under the name of "Metaphysics of expression" by virtue of the fact that what is given is commonly acquired through an expressive or communicative act. However, and despite this conceptual position, the fact is that the presence of myth can be found at the very heart of this philosopher’s philosophy. It should be noted that there is a particular myth that prevails in the clearing of his work, namely the myth of the androgyne. Through this myth it is possible to elucidate the origin of man and the original idea about symbol. (shrink)

En el presente trabajo se desarrollan las bases para la enumeración de las reglas del método a partir del pensamiento filosófico de Eduardo Nicol. En la propuesta temática del autor, amanece la necesidad de repensar el método concediéndole dos funciones preeminentes, tales como son, por un lado, la de servir de cedazo a las diferentes impresiones, así como a los distintos intereses exógenos a la razón buscadora de la verdad.

En el presente artículo, se describen y analizan las características de la metáfora como herramienta retórica y epistemológica desde la perspectiva de Mariano Iberico (1892-1974) en su _Estudio sobre la metáfora_ (1965). Para el filósofo peruano, la metáfora es una instancia mediadora entre lo que sucede fuera del hombre y lo que sucede dentro de él. Es este rasgo mediador el que se revela como posibilidad epistemológica con consecuencias éticas, ya que el conocimiento metafórico se produce a través de mediaciones (...) y aproximaciones que “postulan la existencia de una comunidad espiritual y anímica” entre las diversas esferas de la realidad. Para el análisis, serán útiles la noción de Paul Ricoeur del ser humano como ente mediador y las propuestas sobre la imaginación poética de Gastón Bachelard. (shrink)

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)

Bourrat and Griffiths :33, 2018) have recently argued that most of the evidence presented by holobiont defenders to support the thesis that holobionts are evolutionary individuals is not to the point and is not even adequate to discriminate multispecies evolutionary individuals from other multispecies assemblages that would not be considered evolutionary individuals by most holobiont defenders. They further argue that an adequate criterion to distinguish the two categories is fitness alignment, presenting the notion of fitness boundedness as a criterion that (...) allows divorcing true multispecies evolutionary individuals from other multispecies assemblages and provides an adequate criterion to single out genuine evolutionary multispecies assemblages. A consequence of their criterion is that holobionts, as conventionally defined by hologenome defenders, are not evolutionary individuals except in very rare cases, and for very specific host-symbiont associations. This paper is a critical response to Bourrat and Griffiths’ arguments and a defence of the arguments presented by holobiont defenders. Drawing upon the case of the hologenomic basis of the evolution of sanguivory in vampire bats, I argue that Bourrat and Griffiths overlook some aspects of the biological nature of the microbiome that justifies the thesis that holobionts are evolutionarily different to other multispecies assemblages. I argue that the hologenome theory of evolution should not define the hologenome as a collection of genomes, but as the sum of the host genome plus some traits of the microbiome which together constitute an evolutionary individual, a conception I refer to as the stability of traits conception of the hologenome. Based on that conception I argue that the evidence presented by holobiont defenders is to the point, and supports the thesis that holobionts are evolutionary individuals. In this sense, the paper offers an account of the holobiont that aims to foster a dialogue between hologenome advocates and hologenome critics. (shrink)

Adaptive optics are techniques used for processing the spatial resolution of astronomical images taken from large ground-based telescopes. In this work, computational results are presented for a modified curvature sensor, the tomographic pupil image wavefront sensor, which measures the turbulence of the atmosphere, expressed in terms of an expansion over Zernike polynomials. Convolutional neural networks are presented as an alternative to the TPI-WFS reconstruction. This technique is a machine learning model of the family of artificial neural networks, which are widely (...) known for its performance as modeling and prediction technique in complex systems. Results obtained from the reconstruction of the networks are compared with the TPI-WFS reconstruction by estimating errors and optical measurements. The reconstructed wavefronts from both techniques are compared for wavefronts of 153 Zernike modes. For this case, a detailed comparison and grid search to find the most suitable neural network is performed, searching between multi-layer perceptron, CNN and recurrent networks topologies. In general, the best network was a CNN trained for TPI-WFS reconstruction, achieving better performance than the reconstruction software from TPI-WFS in most of the turbulent profiles, but the most significant improvements were found for higher turbulent profiles that have the lowest r0 values.

The hologenome concept of evolution is a hypothesis about the evolution of animals and plants. It asserts that the evolution of animals and plants was partially triggered by their interactions with their symbiotic microbiomes. In that vein, the hologenome concept posits that the holobiont (animal host + symbionts of the microbiome) is a unit of selection. -/- The hologenome concept has been severely criticized on the basis that selection on holobionts would only be possible if there were a tight transgenerational (...) host-genotype-to-symbiont-genotype connection. As our current evidence suggests that this is not the case for most of the symbiont species that compose the microbiome of animals and plants, the opportunity for holobiont selection is very low in relation to the opportunity for selection on each of the species that compose the host microbiome. Therefore, holobiont selection will always be disrupted ‘from below’, by selection on each of the species that compose the microbiome. -/- This thesis constitutes a conceptual effort to defend philosophically the hologenome concept. I argue that the criticism according to which holobiont selection requires tight transgenerational host-genotype-to-symbiont-genotype connection is grounded on a metaphysical view of the world according to which the biological hierarchy needs to be nested, such that each new level of selection includes every entity from below. Applied to hologenomes, it entails that the hologenome is a collection of genomes, and selection of hologenomes is assumed to entail cospeciation of the host with the species that constitute its microbiome. -/- Against that interpretation, I propose the ‘stability of traits’ account, according to which hologenome evolution is the result of the action of natural selection in a non-nested hierarchical world. In that vein, hologenome evolution does not entail cospeciation, and thus it does not require tight transgenerational host-genotype-to-symbiont-genotype connection. By embracing a multilevel selection perspective, I argue that hologenome evolution results from the simultaneous action of natural selection on each of the lineages that compose the microbiome, and on the assemblage composed by the host genome plus the functional traits of its microbiome. Hologenome selection occurs when the evolution of the traits of the microbiome result from their effects on the fitness of the host, and it can take the form of multilevel selection 1, or multilevel selection 2. In both cases, hologenome selection entails the evolution of microbiome traits, as well as evolution of the host genome, rather than cospeciation of lineages. (shrink)

The search for mechanisms has been a common practice in scientific research. However, since the empiricist critique of causality, and especially during the second third of the twentieth century, other non-mechanistic perspectives—especially deductivism—gained predominance. But the sustained effort of authors such as Michael Scriven, Mario Bunge and especially Wesley Salmon contributed to restoring the respectability of causality and mechanisms in philosophy of science. Some members of the causal family, usually lumped under the name of “new mechanistic philosophy”, emphasize the description (...) of mechanisms, especially causal ones, as a central aspect of explanation and other research practices in several areas of science. This approach offers viable solutions to the various ontological and methodological objections that are opposed to the two traditional approaches. In this work the basic characteristics of three philosophies that highlight the description of mechanisms as a central element to explanation and their suitability for the science of ecology are discussed.

The units or levels of selection debate concerns the question of what kind of biological systems are stable enough that part of their evolution is a result of the process of natural selection acting at their level. Traditionally, the debate has concerned at least two different, though related, questions: the question of the level at which interaction with the environment occurs, and the question of the level at which reproduction occurs. In recent years, biologists and philosophers have discussed a new (...) aspect of this debate, namely the possibility that certain multi-species consortia formed by a host and its microbiome may act as a unit of selection. This thesis, however, has not been without criticism, as it is doubtful that such consortia could meet the conditions required to achieve the degree of stability that would allow them to experience natural selection. The purpose of this paper is to systematically examine such criticisms and to defend the thesis that the holobiont/hologenome can act as a genuine level of selection both in the form of an interactor and in the form of a reproducer. To do so, it will be argued that the microbiome should be characterized in functional rather than taxonomic terms. (shrink)

Schools are an essential part of students’ lives and can promote and facilitate their well-being. Although research on well-being among school-aged children and adolescents has distinguished subjective well-being from social well-being, very few studies examined student’s social well-being at school. SWS is understood as students’ valuation of the circumstances and functioning of their school. This framework posits that the context of the schools can shape students’ perception of feeling integrated and making significant contributions to their schools. However, not much is (...) known regarding the joint contribution of individual, family, and school characteristics to students’ SWS. This study analyzed these joint contributions in a nationally representative sample of 6,389 children and adolescents enrolled in 5th–11th grades. Findings show that being female and younger were individual predictors of SWS. Students’ satisfaction with their family and fewer changes of schools were also significant contributors. When students’ perceptions of their schools were incorporated, the individual and family characteristics decreased or lost significance. In the full model, the highest contribution to SWS was explained by the school-level aggregated perception of school climate. These findings call for integrated policies and practices to foster students’ sense of belonging, feeling integrated, and contribution to their schools, with a focus on school-level interventions to improve SWS through positive and engaging school climates that foster students’ sense of agency.

It is widely held that there is a distinctive norm of assertion. A plausible idea is that there is an analogous, perhaps weaker, norm for indirect communication via implicatures. I argue against this type of proposal. My claim is that the norm of assertion is a social norm governing public updates to the conversational record. Off the record implicatures are not subject to social norms of this type. I grant that, as happens in general with intentional actions, off the record (...) communicative acts may be subject to normative assessments on different levels (for instance, regarding their moral or prudential appropriateness). However, such assessments do not generate distinctive norms that apply to all cases of implicature. (shrink)

The Coronavirus Disease 2019 pandemic, now a global health crisis, has surprised health authorities around the world. Recent studies suggest that the measures taken to curb the spread of the COVID-19 outbreak have generated issues throughout the population. Thus, it is necessary to establish and identify the possible risk factors related to the psychosocial and psychophysiological strain during the COVID-19 outbreak. The present extensive literature review assesses the social, psychological, and physiological consequences of COVID-19, reviewing the impact of quarantine measures, (...) isolation, vast human loss, social and financial consequences in the family’s economies, and its impact on the psychological health of the population. We also discussed the effect of psychophysiological factors, considering the impact of physical inactivity and modifications in nutritional habits, at psychological and physiological levels. The present review includes an actualized to date bibliography, articles for which were methodologically analyzed to verify they met the standards of quality and scientific accuracy. Authors understand the pandemic as a multifactorial event for which only a profound and extensive analysis would lead to better compression and efficient intervention in the near future. (shrink)

Symbiosis plays a fundamental role in contemporary biology, as well as in recent thinking in philosophy of biology. The discovery of the importance and universality of symbiotic associations has brought new light to old debates in the field, including issues about the concept of biological individuality. An important aspect of these debates has been the formulation of the hologenome concept of evolution, the notion that holobionts are units of natural selection in evolution. This review examines the philosophical assumptions that underlie (...) recent proposal of the hologenome concept of evolution, and traces those debates back in time to their historical origins, to the moment when the connection between the topics of symbiosis and biological individuality first caught the attention of biologists. The review is divided in two parts. The first part explores the historical origins of the connection between the notion of symbiosis and the concept of biological individuality, and emphasizes the role of A. de Bary, R. Pound, A. Schneider and C. Merezhkowsky in framing the debate. The second part examines the hologenome concept of evolution and explores four parallelisms between contemporary debates and the debates presented in the first part of the essay, arguing that the different debates raised by the hologenome concept were already present in the literature. I suggest that the novelty of the hologenome concept of evolution lies in the wider appreciation of the importance of symbiosis for maintaining life on Earth as we know it. Finally, I conclude by suggesting the importance of exploring the connections among contemporary biology, philosophy of biology and history of biology in order to gain a better understanding of contemporary biology.

Holobionts are symbiotic assemblages composed by a host plus its microbiome. The status of holobionts as individuals has recently been a subject of continuous controversy, which has given rise to two main positions: on the one hand, holobiont advocates argue that holobionts are biological individuals; on the other, holobiont detractors argue that they are just mere chimeras or ecological communities, but not individuals. Both parties in the dispute develop their arguments from the framework of the philosophy of biology, in terms (...) of what it takes for a “conglomerate” to be considered an interesting individual from a biological point of view. However, the debates about holobiont individuality have important ontological implications that have remained vaguely explored from a metaphysical framework. The purpose of this paper is to cover that gap by presenting a metaphysical approach to holobionts individuality. Drawing upon a conception of natural selection that puts the focus on the transgenerational recurrence of the traits and that supports the thesis that holobionts are units of selection, we argue that holobionts bear emergent traits and exert downward powers over the entities that compose them. In this vein, we argue, a reasonable argument can be made for conceiving holobionts as emergent biological individuals. (shrink)

Given one conception of biological individuality (evolutionary, physiological, etc.), can a holobiont – that is the host + its symbiotic (mutualistic, commensalist and parasitic) microbiome – be simultaneously a biological individual and an ecological community? Herein, we support this possibility by arguing that the notion of biological individuality is part‐dependent. In our account, the individuality of a biological ensemble should not only be determined by the conception of biological individuality in use, but also by the biological characteristics of the part (...) of the ensemble under investigation. In the specific case of holobionts, evaluations of their individuality should be made either host‐relative or microbe‐relative. We support the claim that biological individuality is part‐dependent by drawing upon recent empirical evidence regarding the physiology of hosts and microbes, and the recent characterization of the ‘demibiont’. Our account shows that contemporary disagreements about the individuality of the holobiont derive from an incorrect understanding of the ontology of biological individuality. We show that collaboration between philosophers and biologists can be very fruitful in attempts to solve some contemporary biological debates. (shrink)

Food choices are a key determinant of dietary intake, with brain regions, such as the mesolimbic and prefrontal cortex maturing at differential rates into adulthood. More needs to be understood about developmental changes in healthy and unhealthy food perceptions and preference. We investigated how food perceptions and preference vary as a function of age and how food attributes impact age-related changes. One hundred thirty-nine participants completed computerized tasks to rate high-calorie and low-calorie food cues for taste, health, and liking, followed (...) by 100 binary food choices based on each participant’s ratings. Dietary self-control was considered successful when the healthier food was chosen. Self-control success ratio was the proportion of success trials over total number of choices. Beta-weights for health and taste were calculated as each attribute’s influence on food preference. Adiposity measurements included BMI z-score and waist-to-height ratio. High-calorie foods were rated more tasty and less healthy with increasing age. Older participants liked high-calorie foods more, and β-taste was associated with age. Significant age-by-WHtR interactions were observed for health and taste ratings of high-calorie foods, β-taste, and marginally for preference of high-calorie foods. Stratifying by WHtR, we found age-related increases in taste and preference ratings of high-calorie foods in the high WHtR group alone. In contrast, age-related decreases in health ratings of high-calorie foods were significant in the low WHtR group alone. Age and β-taste were significantly associated in the high WHtR group and only marginally significant with low WHtR. Although participants rated low-calorie foods as less tasty and less healthy with increasing age, there was no association between age and preference for low-calorie foods. Participants made faster food choices with increasing age regardless of WHtR, with a significant age-by-WHtR interaction on reaction time. There were no age-related effects in self-control success ratio and β-health. These results suggest that individual differences in age and central adiposity play an important role in preference for high-calorie foods, and a higher importance of food tastiness in food choice may contribute to greater preference for high-calorie foods with increasing age.

Recent research in philosophy of science has shown that scientists rely on a plurality of strategies to develop successful explanations of different types of phenomena. In the case of biology, most of these strategies go far beyond the traditional and reductionistic models of scientific explanation that have proven so successful in the fundamental sciences. Concretely, in the last two decades, philosophers of science have discovered the existence of at least two different types of scientific explanation at work in the biological (...) sciences, namely: mechanistic and structural explanations. Despite the growing evidence about the radically different nature of these two types of explanation, no inquiry has been conducted to date to determine the ontological reasons that might underlie these differences, nor the way in which these types of explanations can be systematically related with each other. Here, we aim to cover this gap by connecting this plurality of research strategies with the existence of emergent levels of reality. We argue that the existence of these different—and apparently incompatible—explanatory strategies to account for biological phenomena derives from the existence of “ontological jumps” in nature, which generate different regimes of causation that in turn demand the development of different explanatory frameworks. We identify two of these strategies—mechanistic modelling and network modelling—and connect them to the existence of two ontological regimes of causation. Finally, we relate them with each other in a systematic way. In this vein, our paper provides an ontological justification for the plurality of explanatory strategies that we see in the life sciences. (shrink)

The objective of this research is to develop accurate forecasting models for chlorophyll-α concentrations at various depths in El Mar Menor, Spain. Chlorophyll-α plays a crucial role in assessing eutrophication in this vulnerable ecosystem. To achieve this objective, various deep learning forecasting techniques, including long short-term memory, bidirectional long short-term memory and gated recurrent uni networks, were utilized. The models were designed to forecast the chlorophyll-α levels with a 2-week prediction horizon. To enhance the models’ accuracy, a sliding window method (...) combined with a blocked cross-validation procedure for time series was also applied to these techniques. Two input strategies were also tested in this approach: using only chlorophyll-α time series and incorporating exogenous variables. The proposed approach significantly improved the accuracy of the predictive models, no matter the forecasting technique employed. Results were remarkable, with |$\overline{\sigma}$| values reaching approximately 0.90 for the 0.5-m depth level and 0.80 for deeper levels. The proposed forecasting models and methodologies have great potential for predicting eutrophication episodes and acting as decision-making tools for environmental agencies. Accurate prediction of eutrophication episodes through these models could allow for proactive measures to be implemented, resulting in improved environmental management and the preservation of the ecosystem.

Philippe Huneman has recently questioned the widespread application of mechanistic models of scientific explanation based on the existence of structural explanations, i.e. explanations that account for the phenomenon to be explained in virtue of the mathematical properties of the system where the phenomenon obtains, rather than in terms of the mechanisms that causally produce the phenomenon. Structural explanations are very diverse, including cases like explanations in terms of bowtie structures, in terms of the topological properties of the system, or in (...) terms of equilibrium. The role of mathematics in bowtie structured systems and in topologically constrained systems has recently been examined in different papers. However, the specific role that mathematical properties play in equilibrium explanations requires further examination, as different authors defend different interpretations, some of them closer to the new-mechanistic approach than to the structural model advocated by Huneman. In this paper, we cover this gap by investigating the explanatory role that mathematics play in Blaser and Kirschner’s nested equilibrium model of the stability of persistent long-term human-microbe associations. We argue that their model is explanatory because: i) it provides a mathematical structure in the form of a set of differential equations that together satisfy an ESS; ii) that the nested nature of the ESSs makes the explanation of host-microbe persistent associations robust to any perturbation; iii) that this is so because the properties of the ESS directly mirror the properties of the biological system in a non-causal way. The combination of these three theses make equilibrium explanations look more similar to structural explanations than to causal-mechanistic explanation. (shrink)

I argue that if there are nondisabled reasons to believe p, then there cannot be nondisabled reasons to believe something incompatible with p. I first defend a restricted version of the view, which applies only to situations where the relevant agent has complete evidence. Then, I argue for a generalized version of the view, which holds regardless of the agent's evidence. As a related result, I show that, given plausible assumptions, there cannot be nondisabled reasons to believe something false.

This paper aims to offer a new argument in defence bacterial species pluralism. To do so, I shall first present the particular issues derived from the conflict between the non-theoretical understanding of species as units of classification and the theoretical comprehension of them as units of evolution.

Finally, I shall show how my argument provides a new source of defence for bacterial pluralism. (shrink)
