Biological regulation is what allows an organism to handle the effects of a perturbation, modulating its own constitutive dynamics in response to particular changes in internal and external conditions. With the central focus of analysis on the case of minimal living systems, we argue that regulation consists in a specific form of second-order control, exerted over the core regime of production and maintenance of the components that actually put together the organism. The main argument is that regulation requires a distinctive (...) architecture of functional relationships, and specifically the action of a dedicated subsystem whose activity is dynamically decoupled from that of the constitutive regime. We distinguish between two major ways in which control mechanisms contribute to the maintenance of a biological organisation in response to internal and external perturbations: dynamic stability and regulation. Based on this distinction an explicit definition and a set of organisational requirements for regulation are provided, and thoroughly illustrated through the examples of bacterial chemotaxis and the lac-operon. The analysis enables us to mark out the differences between regulation and closely related concepts such as feedback, robustness and homeostasis. (shrink)

Our aim in the present paper is to approach the nature of life from the perspective of autonomy, showing that this perspective can be helpful for overcoming the traditional Cartesian gap between the physical and cognitive domains. We first argue that, although the phenomenon of life manifests itself as highly complex and multidimensional, requiring various levels of description, individual organisms constitute the core of this multifarious phenomenology. Thereafter, our discussion focuses on the nature of the organization of individual living entities, (...) proposing autonomy as the main concept to grasp it. In the second part of the article we show how autonomy is also fundamental to explaining major evolutionary transitions, in an attempt to rethink evolution from the point of view of the organizational structure of the entities/organisms involved. This gives further support to the idea of autonomy not only as a key to understanding life in general but also the complex expressions of it that we observe on our planet. Finally, we suggest a possible general principle that underlies those evolutionary transitions, which allow for the open-ended redefinition of autonomous systems: namely, the relative dynamic decoupling that must be articulated among distinct parts, modules or modes of operation in these systems.

Since Darwin it is widely accepted that natural selection (NS) is the most important mechanism to explain how biological organisms—in their amazing variety—evolve and, therefore, also how the complexity of certain natural systems can increase over time, creating ever new functions or functional structures/relationships. Nevertheless, the way in which NS is conceived within Darwinian Theory already requires an open, wide enough, functional domain where selective forces may act. And, as the present paper will try to show, this becomes even more (...) evident if one looks into the problem of origins. If there was a time when NS was not operating (as it is quite reasonable to assume), where did that initial functional diversity, necessary to trigger off the process, come from? Self-organization processes may be part of the answer, as many authors have claimed in recent years, but surely not the complete one. We will argue here that a special type of self-maintaining organization, arising from the interplay among a set of different endogenously produced constraints (pre-enzymatic catalysts and primitive compartments included), is required for the appearance of functional diversity in the first place. Starting from that point, NS can progressively lead to new (and, at times, also more complex) organizations that, in turn, provide wider functional variety to be selected for, enlarging in this way the range of action and consequences of the mechanism of NS, in a kind of mutually enhancing effect.

In this paper we explore the organizational conditions underlying the emergence of organisms at the multicellular level. More specifically, we shall propose a general theoretical scheme according to which a multicellular organism is an ensemble of cells that effectively regulates its own development through collective mechanisms of control of cell differentiation and cell division processes. This theoretical result derives from the detailed study of the ontogenetic development of three multicellular systems and, in particular, of their corresponding cell-to-cell signaling networks. The (...) case study supports our claim that a specific type of functional integration among the cells of a multicellular ensemble , is required for it to qualify as a proper organism. Finally, we argue why a multicellular system exhibiting this type of functionally differentiated and integrated developmental organization becomes a self-determining collective entity and, therefore, should be considered as a second-order autonomous system.

In this short contribution we explore the historical roots of recent synthetic approaches in biology and try to assess their real potential, as well as identify future hurdles or the reasons behind some of the main difficulties they currently face. We suggest that part of these difficulties might not be just the result of our present lack of adequate technical skills or understanding, but could spring directly from the nature of the biological phenomenon itself. In particular, if life is conceived (...) as autonomy in open-ended evolution, which would help to explain the highly complex and dynamic organization of the simplest known organisms (i.e., genetically-instructed cellular metabolisms), external synthetic implementations of such systems, or interventions on them, are bound to interfere with some of their characteristic transformation processes, both at the ontogenetic and phylogenetic scales. In any case, this will prove very revealing and productive, technologically and scientifically speaking, since the knowledge gathered from those implementations/interventions will be extremely valuable in establishing our capacities and limitations to fully comprehend, utilize, and expand the living domain as we know it today.

During the last decades the question of defining life has gained increased interest but, at the same time, the difficulty in reaching consensus on a possible answer has led many to skeptical positions. This, in turn, has raised a wider debate about why defining life is so hard and controversial. Such a debate introduces additional aspects to be considered, like the role and nature of a definition of life itself. In this paper, we will focus on those aspects, arguing that (...) progress can be made if we conceive definitions of life as open heuristic tools that contribute to develop specific research strategies in the biological sciences and, more generally, to increase our understanding of life’s complexity. In contrast with pragmatic or operationalist approaches, we will defend that definitions of life comprise a set of ontological assumptions, together with an inherent unifying vocation, so they should be subject to comparison and critical assessment, closely related to the success or failure of the corresponding research programs, but also to the success or failure in establishing well-grounded interconnections among the latter. We consider that the search for a more coherent, integrated and generalized theory of biology cannot be pursued without keeping an empirical standpoint, and the exercise of defining life should not be taken as an obstacle but as a valuable instrument to achieve that goal.

In this paper we review and argue for the relevance of the concept of open-ended evolution in biological theory. Defining it as a process in which a set of chemical systems bring about an unlimited variety of equivalent systems that are not subject to any pre-determined upper bound of organizational complexity, we explain why only a special type of self-constructing, autonomous systems can actually implement it. We further argue that this capacity derives from the ‘dynamic decoupling’ (in its minimal or (...) most basic sense: the phenotype–genotype decoupling) by means of which a radically new way of material organization (minimal living organization) is achieved, allowing for the long-term sustenance of systems whose individual-metabolic and collective-historical pathways become thereafter deeply intertwined.

We developed a survey to explore the association between misconduct and stress, potential stressors and other possible contributing f.

In this chapter we offer a critical analysis of organizational models about the process of origins of life and, thereby, a reflection about life itself (understood in a general, minimal sense). We begin by demarcating the idea of organization as an explanatory construct, linking it to the complex relationships and transformations that the material parts of (proto-)biological systems establish to maintain themselves under non-equilibrium dynamic conditions. The diverse ways in which this basic idea has been applied within the prebiotic field (...) are then reviewed in relative detail. We distinguish between “network” and “protocell” approaches, discussing their specific implications and explaining the greater relevance of the latter in the current state of affairs. Despite the key role that such organizational approaches play (and should keep playing) to advance on the problem of primordial biogenesis, the second half of our contribution is devoted to argue that they must be combined with other explanatory accounts, which go beyond the physiology of any single (proto-)organism. With that aim, we underline the fundamental differences between the autonomous, metabolic dynamics that individual (proto-)cells perform and the evolutionary and ecological dynamics that take place in a collective and trans-generational dimension. Apart from obvious gaps in the characteristic temporal and spatial scales involved, the corresponding causal and interactive regimes also reveal themselves as neatly distinct, what is reflected in the unpaired functional integration and the agent behavior displayed by biological individuals. Nevertheless, any living organism (and life in a wider, general sense) derives from the deep interweaving of those two phenomenological domains: namely, the “individual-metabolic” and the “collective-evolutionary” domains. At the end of the chapter, we propose the principle of dynamical decoupling as the core idea to develop a more comprehensive theoretical framework to understand how this intricate, causally asymmetric connection must be articulated during the actual process of biogenesis (as it happened here on Earth or anywhere else in the universe), so that life’s minimal complexity threshold is reached.

Este artículo analiza la dictadura del proletariado desde las revisiones en la coyuntura político-filosófica de los años setenta, marcada por la emergencia de la crisis del marxismo y la revisión antiestalinista de los principales conceptos bolcheviques, hasta la actualidad. Para ello, contrastamos las obras de Antoni Domènech y Étienne Balibar y sus tradiciones filosóficas respectivas destacando sus encuentros y problemas comunes. Por otro lado, hemos decidido acometer la dictadura del proletariado a partir de tres oposiciones: clase contra clase/alianza de clases, (...) dictadura comisaria/dictadura soberana, planificación/mercado.

Psychological flexibility is a key concept of acceptation and commitment therapy. This factor has been linked with psychological wellbeing and associated factors, such as quality of life, in cancer patients. These and other positive results of acceptation and commitment therapy in cancer patients found in previous research could be enhanced by using mhealth tools. A three-arm randomized superiority clinical trial, with a pre-post-follow-up repeated measures intergroup design with a 1:1:1 allocation ratio is proposed. A hundred and twenty cancer patients will (...) be randomly assigned to one of the following interventions: face-to-face ACT + mobile application, face-to-face ACT, and Waitlist control group. The primary expected outcome is to observe significant improvements in psychological flexibility acceptance and action questionnaire- II in the face-to-face ACT + app group, after comparing baseline and post-treatment scores, and the scores will remain stable in the two assessment points, 3 and 6 months after the intervention. Secondary expected outcomes are significant increasing scores in quality of life and post-traumatic-growth, and significant decreasing scores in anxiety and depression, insomnia and fatigue at the same assessment points. Also, it is expected that the scores of this group will be higher than the scores of the face-to-face ACT group and the waitlist control group. This study aims to assess the efficacy of a combined intervention for psychological flexibility and associated symptoms in cancer patients. The results of this protocol may help to consider the use of acceptation and commitment therapy and mhealth applications in cancer settings as a valid therapeutic choice.Clinical Trial Registration[www.ClinicalTrials.gov], identifier [NCT05126823].

Aims: Attentional bias, alcohol craving, and anxiety have important implications in the development and maintenance of alcohol use disorder. The current study aims to test the effectiveness of a Virtual Reality Cue-Exposure Therapy to reduce levels of alcohol craving and anxiety and prompt changes in AB toward alcohol content.Method: A 49-year-old male participated in this study, diagnosed with severe AUD, who also used tobacco and illicit substances on an occasional basis and who made several failed attempts to cease substance misuse. (...) The protocol consisted of six VR-CET booster sessions and two assessment sessions over the course of 5 weeks. The VR-CET program consisted of booster therapy sessions based on virtual reality exposure to preferred alcohol-related cues and contexts. The initial and final assessment sessions were focused on exploring AB, alcohol craving, and anxiety using paper-and-pencil instruments and the eye-tracking and VR technologies at different time points.Results: Pre and post assessment sessions indicated falls on the scores of all instruments assessing alcohol craving, anxiety, and AB.Conclusions: This case report, part of a larger project, demonstrates the effectiveness of the VR-CET booster sessions in AUD. In the post-treatment measurements, a variety of instruments showed a change in the AB pattern and an improvement in craving and anxiety responses. As a result of the systematic desensitization, virtual exposure gradually reduced the responses to significant alcohol-related cues and contexts. The implications for AB, anxiety and craving are discussed. (shrink)

We begin with a theory of thought as a biocognition not precisely situated in the individual, and still less in the brain alone, but deriving from a shared field of bioinformation. The structure of associations among elements of speech may reflect the structure of this field. Then we demonstrate that the analysis of the structure of the scientific discourse applied within this logic shows the fractal structure of the field of bioinformation. We also show that scientific culture can be interpreted (...) as a cultural model. So, scientific culture would be the elaboration of a cultural scenario in which each human being is another "myself" according to circumstances, an identification making a relationship of aid possible. This aid relationship is governed by an energy equilibrium defined by the cultural scenario, and may be calculated according to fractal theory. The result is a fractal model of consciousness and of the energies at work, whose equilibrium is necessary for the correct functioning of the human being. The consequences are determined concerning the reinsertion of the logic of the culture within the purely objective logic of medicine, in particular that of "giving-receiving" inherent in all cultures, even at the levels of giving birth in the context of modern medicine. We thank R. Ruiz-Banos for a long-time fruitful collaboration in the field of scientometrics. (shrink)

RESUMEN Partiendo de algunas experiencias del presente, se retoma la interpretación nietzs cheana del resentimiento para explorar la complejidad y ambivalencia del fenómeno e iluminar cuestiones actuales. Así, se vinculan dos tendencias y sus implicaciones: cómo el resentimiento genera la fijación de una identidad amenazadora que lleva a la estigmatización de un otro, a la vez como una forma de rechazo de la contingencia histórica; y cómo el vínculo del resentimiento con la temporalidad, en particular con un tipo de memoria, (...) produce una incapacidad para asumirla creadoramente. Esta reflexión deja abiertas preguntas sobre cómo los cuerpos afectados por el resen timiento pueden revertirlo y dar lugar a formas más vitales de relación con el mundo. ABSTRACT On the basis of selected experiences from the present, the article revisits the Nietzschean interpretation of resentment in order to explore the complexity and ambivalence of the phenomenon and shed light on current issues. To that effect, it connects two tendencies and their implications: the manner in which resentment generates the fixation of a threatening identity that leads to the stigmatization of an other, which, at the same time, involves a rejection of historical contingency; and the manner in which the link between resentment and temporality, in particular with a type of memory, produces an incapacity to assume it creatively. This reflec tion leaves questions open regarding how bodies affected by resentment can twist it around and give rise to more vital forms of relating to the world. (shrink)

Brazilian educator, Paulo Freire, best known for his work Pedagogy of the Oppressed, challenged education plans that contributed to the marginalization of minorities and the poor. Freire believed that education should be used for liberation by helping learners reflect on their experiences historically, giving immediate reality to issues of racism, sexism, and the exploitation of workers. Known as one of the most influential theoretical innovators of the twentieth century, his views have left a significant mark on progressive thinkers about education (...) and liberation. Reinventing Paulo Freire is an homage to him by protégé Antonia Darder. Here, she explores the legacy of Freire, interviews eight former students who studied him-- now teachers themselves, and reflects on the teaching practice as demonstrated by Freire himself. The interviews take the form of first person narratives; the epilogue consists simply of a letter and a poem. (shrink)

Just as bodily actions are things you do with your body, mental actions are things you do with your mind. Both are different from things that merely happen to you. Where does the idea of mental action come from? What are mental actions? And why do they matter in philosophy? These are the three main questions answered in this paper. Section 1 introduces mental action through a brief history of the topic in philosophy. Section 2 explains what it is to (...) be a mental action in terms of intentional action. Section 3 argues that the fact that we can perform mental actions has some striking consequences concerning mental content. Section 4 shows how mental action helps to explain some important facts about self-knowledge and the normativity of thought. The conclusion mentions two further fruitful avenues for philosophical research on mental action. (shrink)

Background Informed consent is often cited as the “cornerstone” of research ethics. Its intent is that participants enter research voluntarily, with an understanding of what their participation entails. Despite agreement on the necessity to obtain informed consent in research, opinions vary on the threshold of disclosure necessary and the best method to obtain consent. We aimed to investigate Australian researchers’ views on, and their experiences with, obtaining informed consent. Methods Semi-structured interviews were conducted with 23 researchers from NSW institutions, working (...) in various fields of research. Interviews were analysed and coded to identify themes. Results Researchers reported that consent involved information disclosure, understanding and a voluntary decision. They emphasised the variability of consent interactions, which were dependent on potential participants’ abilities and interests, study complexity and context. All researchers reported providing written information to potential participants, yet questioned the readability and utility of this information. The majority reported using signed consent forms to ‘operationalise’ consent and reported little awareness of, and lack of support in implementing more dynamic informed consent procedures, such as verbal informed consent, that was fit for the purposes of their studies. Views on Human Research Ethics Committees varied. Some reported inconsistent, arduous inputs on the information form and consent process. Others expressed reliance on HRECs for guidance, viewing them as institutional safeguards. Conclusions This study highlights the importance of transparent relationships, both between researchers and participants, and between researchers and HRECs. Where the relationship with study participants was reported as more robust, researchers felt that they were better able to ensure participants made better, more informed decisions. Where the relationship with HRECs was reported as more robust, researchers were more likely to view them as institutional safeguards, rather than as bureaucratic hindrances. Conscientious and mindful researchers are paramount to ensuring the procedure accommodates individual requirements. This study advocates that when designing ethical informed consent practices, researchers should be integrated as autonomous players with a positive input on the process, rather than, in the worst case, predatory recruiters to be curtailed by information forms and oversight.

ABSTRACT Recently, the hypothesis that purely evaluative disputes are metalinguistic negotiations has gained traction. I resist a strong version of that hypothesis, and argue that some of those disputes are not metalinguistic negotiations. To defend that claim, I argue that metalinguistic negotiations have three linguistic properties that some purely evaluative disputes lack. First, in a metalinguistic negotiation it is felicitous to embed the dispute-initial statement under the subjective attitude verb consider; second, a speaker can reply to that initial statement by (...) using a metalinguistic comparative; and, third, such negotiations address metalinguistic questions under discussion. Some purely evaluative disputes lack these properties, which suggests that they are not metalinguistic negotiations. (shrink)

Aesthetic value empiricism claims that the aesthetic value of an object is grounded in the value of a certain kind of experience of it. The most popular version of value empiricism, and a dominant view in contemporary philosophical aesthetics more generally, is aesthetic hedonism. Hedonism restricts the grounds of aesthetic value to the pleasure enjoyed in the right kind of experience. But hedonism does not enjoy any clear advantage over a more permissive alternative version of value empiricism. This alternative is (...) aesthetic liberalism. On this view, an object’s aesthetic value is fully grounded in any value—not just the hedonic value—of a correct and complete experience of its sensory features. To demonstrate the advantages of liberalism over hedonism, I apply both views to analyze the aesthetic value of the Spring Temple Buddha and Anselm Kiefer’s Seraphim. I detail four advantages of liberalism over hedonism, and I conclude by defending liberalism from two kinds of objection. (shrink)

Basic actions are those intentional actions performed not by doing any other kind of thing intentionally. Complex actions involve doing one kind of thing intentionally by doing another kind of thing intentionally. There are both basic and complex mental actions. Some complex mental actions have a striking feature that has not been previously discussed: they have several distinct contents at once. This chapter introduces and explains this feature, here called “content plurality.” This chapter also argues for the philosophical significance of (...) this feature. The existence of content plurality offers a new explanation of transparent self-knowledge and suggests a new theory of inference. It also opens up a new conception of the relation between decisions to act and judgments about what ought to be done. (shrink)

I defend a metalinguistic account of Mates's puzzle: sentences where synonymous expressions cannot be substituted salva veritate. If Andrea thinks that attorneys are different from lawyers, and she thinks that Fiona is the former but not the latter, we may hesitate to substitute ‘lawyer’ for ‘attorney’ in ‘Andrea believes that Fiona is an attorney’, even though ‘lawyer’ and ‘attorney’ are synonymous. I argue that these sentences report de re beliefs about linguistic expressions, thereby blocking such substitutions, and I offer a (...) compositional derivation of their meaning. (shrink)

You can come to know that you believe that p partly by reflecting on whether p and then judging that p. Call this procedure “the transparency method for belief.” How exactly does the transparency method generate known self-attributions of belief? To answer that question, we cannot interpret the transparency method as involving a transition between the contents p and I believe that p. It is hard to see how some such transition could be warranted. Instead, in this context, one mental (...) action is both a judgment that p and a self-attribution of a belief that p. The notion of embedded mental action is introduced here to explain how this can be so and to provide a full epistemic explanation of the transparency method. That explanation makes sense of first-person authority and immediacy in transparent self-knowledge. In generalized form, it gives sufficient conditions on an attitude’s being known transparently.

I argue against the view that metalinguistic usage is a form of conversational implicature. That view, suggested by Thomasson (Anal Philos 57(4):1-28, 2016) and Belleri (Philos Stud 174(9):2211–2226, 2017), has been most recently fleshed out by Mankowitz (Synthese 199:5603–5622, 2021). I provide two types of criticism to the implicature view. From an empirical point of view, metalinguistic usage differs in key respects from standard cases of conversational implicature. From a conceptual standpoint, I argue that the calculation algorithm provided by the (...) implicature view makes undesirable predictions. Although my main objective is negative, I end the paper by sketching an alternative neo-Stalnakerian view of metalinguistic usage, that can be gathered from work by Barker (Linguist Philos 25(1):1–36, 2002; Inquiry 56(2–3):240–257, 2013) and others.
