Tarski's theory of truth brings out the question of whether he intended his theory to be a correspondence theory of truth and whether, whatever his intentions, his theory is, in fact, a correspondence theory. The aim of this paper is to answer both questions. The answer to the first question depends on Tarski's relevant assertions on semantics and his conception of truth. In order to answer the second question Popper's and Davidson's interpretations of Tarski's truth theory are examined; to this (...) end both Tarski's definition of truth in terms of satisfaction and the T-sentences are taken into account.

The veil of ignorance has been used often as a tool for recommending what justice requires with respect to the distribution of wealth. We complete Harsanyi's model of the veil of ignorance by appending information permitting objective comparisons among persons. In order to do so, we introduce the concept of objective empathy. We show that the veil-of-ignorance conception of John Harsanyi, so completed, and Ronald Dworkin's, when modelled formally, recommend wealth allocations in conflict with the prominently espoused view that priority (...) should be given to the less able in wealth allocation. We finally argue that the veil of ignorance should be rejected as a tool for discovering what justice requires. (shrink)
Since Darwin, Biology has been framed on the idea of evolution by natural selection, which has profoundly influenced the scientific and philosophical comprehension of biological phenomena and of our place in Nature. This book argues that contemporary biology should progress towards and revolve around an even more fundamental idea, that of autonomy. Biological autonomy describes living organisms as organised systems, which are able to self-produce and self-maintain as integrated entities, to establish their own goals and norms, and to promote the (...) conditions of their existence through their interactions with the environment. Topics covered in this book include organisation and biological emergence, organisms, agency, levels of autonomy, cognition, and a look at the historical dimension of autonomy. The current development of scientific investigations on autonomous organisation calls for a theoretical and philosophical analysis. This can contribute to the elaboration of an original understanding of life - including human life - on Earth, opening new perspectives and enabling fecund interactions with other existing theories and approaches. This book takes up the challenge. (shrink)

Why scientists reach an agreement on new experimental methods when there are conflicts of interest about the evidence they yield? I argue that debiasing methods play a crucial role in this consensus, providing a warrant about the impartiality of the outcome regarding the preferences of different parties involved in the experiment. From a contractarian perspective, I contend that an epistemic pre-requisite for scientists to agree on an experimental method is that this latter is neutral regarding their competing interests. I present (...) two medical experiments (on smallpox inoculation and Mesmerism) in which debiasing procedures such as blinding and data tabulation provided warrants of impartiality that made people agree on the experimental design even if they disagreed on the outcome.

Most everyday tasks involve multiple modalities, which raises the question of how the processing of these modalities is coordinated by the cognitive system. In this paper, we focus on the coordination of visual attention and linguistic processing during speaking. Previous research has shown that objects in a visual scene are fixated before they are mentioned, leading us to hypothesize that the scan pattern of a participant can be used to predict what he or she will say. We test this hypothesis (...) using a data set of cued scene descriptions of photo-realistic scenes. We demonstrate that similar scan patterns are correlated with similar sentences, within and between visual scenes; and that this correlation holds for three phases of the language production process (target identification, sentence planning, and speaking). We also present a simple algorithm that uses scan patterns to accurately predict associated sentences by utilizing similarity-based retrieval. (shrink)
The first form of the inside-outside dichotomy appears as a self-encapsulated system with an active border. These systems are based on two complementary but asymmetric processes: constructive and interactive. The former physically constitute the system as a recursive network of component production, defining an inside. The maintenance of the constructive processes implies that the internal organization also constrains certain flows of matter and energy across the border of the system, generating interactive processes. These interactive processes ensure the maintenance of the (...) constructive processes thus specifying a meaningful outside. Upon this basic form of identity formation, the evolutionary and historical domain is open for the emergence of a whole hierarchy and ecology of insides and outsides. These which mutually subsume and collaborate in the maintenance of the essential inside-outside dichotomy that defines the conditions of possibility of the subjects and the worlds they generate.

Substantial efforts have recently been made to reform the physician-patient relationship, particularly toward replacing the `silent world of doctor and patient' with informed patient participation in medical decision-making. This 'new ethos of patient autonomy' has especially insisted on the routine provision of informed consent for all medical interventions. Stronly supported by most bioethicists and the law, as well as more popular writings and expectations, it still seems clear that informed consent has, at best, been received in a lukewarm fashion by (...) most clinicians, many simply rejecting what they commonly refer to as the `myth of informed consent'. The purpose of this book is to defuse this seemingly intractable controversy by offering an efficient and effective operational model of informed consent. This goal is pursued first by reviewing and evaluating, in detail, the agendas, arguments, and supporting materials of its proponents and detractors. A comprehensive review of empirical studies of informed consent is provided, as well as a detailed reflection on the common clinician experience with attempts at informed consent and the exercise of autonomy by patients. In the end, informed consent is recast as a management tool for pursuing clinically and ethically important goods and values that any clinician should see as meriting pursuit. Concurrently, the model incorporates a flexible, anticipatory approach that recognizes that no static, generic ritual can legitimately pursue the quite variable goods and values that may be at stake with different patients in different situations. Finally, efficiency of provision is addressed by not pursuing the unattainable and ancillary. Throughout, the traditional principle of beneficence is appealed to toward articulating an operational model of informed consent as an intervention that is likely to change outcomes at the bedside for the better.

When people communicate, they coordinate a wide range of linguistic and non-linguistic behaviors. This process of coordination is called alignment, and it is assumed to be fundamental to successful communication. In this paper, we question this assumption and investigate whether disalignment is a more successful strategy in some cases. More specifically, we hypothesize that alignment correlates with task success only when communication is interactive. We present results from a spot-the-difference task in which dyads of interlocutors have to decide whether they (...) are viewing the same scene or not. Interactivity was manipulated in three conditions by increasing the amount of information shared between interlocutors. We use recurrence quantification analysis to measure the alignment between the scan-patterns of the interlocutors. We found that interlocutors who could not exchange feedback aligned their gaze more, and that increased gaze alignment correlated with decreased task success in this case. When feedback was possible, in contrast, interlocutors utilized it to better organize their joint search strategy by diversifying visual attention. This is evidenced by reduced overall alignment in the minimal feedback and full dialogue conditions. However, only the dyads engaged in a full dialogue increased their gaze alignment over time to achieve successful performances. These results suggest that alignment per se does not imply communicative success, as most models of dialogue assume. Rather, the effect of alignment depends on the type of alignment, on the goals of the task, and on the presence of feedback. (shrink)
Affordable light detection and ranging sensors are becoming available for tasks such as simultaneous localization and mapping in robotics and autonomous driving; however, these sensors offer less quality data of lower resolution that hinders the performance of registration methods. The deep learning based approaches seem to be sensitive to these data flaws. Specifically, a state-of-the-art deep learning-based approach failed to produce meaningful results after several attempts to carry out transfer learning over a dataset collected indoors with one such affordable sensors. (...) The paper introduces a hybrid approach combining two well-established registration techniques, the iterative closest point algorithm and the normal distributions transform that achieves good performance on the SLAM task over the same dataset.

Functional language is ubiquitous in ecology, mainly in the researches about biodiversity and ecosystem function. However, it has not been adequately investigated by ecologists or philosophers of ecology. In the contemporary philosophy of ecology we can recognize a kind of implicit consensus about this issue: while the etiological approaches cannot offer a good concept of function in ecology, Cummins’ systemic approach can. Here we propose to go beyond this implicit consensus, because we think these approaches are not adequate for ecology. (...) We argue that a sound epistemological framework to function in ecology is to be found in organizational approaches. In this line, we define function in ecology as a precise effect of a given constraint on the ecosystem flow of matter and energy performed by a given item of biodiversity, within a closure of constraints. We elaborate on this definition by developing a case study of a bromeliad ecosystem. (shrink)
InCarm.4.1 Horace asks Venus to stop waging war against him, who is now over fifty, and suggests that she should set her aim instead on Paulus Maximus, a young and passionate nobleman who will be happy to obey Venus' orders.
The organizational account of biological functions interprets functions as contributions of a trait to the maintenance of the organization that, in turn, maintains the trait. As has been recently argued, however, the account seems unable to provide a unified grounding for both intra- and cross-generation functions, since the latter do not contribute to the maintenance of the same organization which produces them. To face this ‘ontological problem’, a splitting account has been proposed, according to which the two kinds of functions (...) require distinct organizational definitions. In this article, we propose a solution for the ontological problem, by arguing that intra- and cross-generation functions can be said to contribute in the same way to the maintenance of the biological organization, characterized in terms of organizational self-maintenance. As a consequence, we suggest maintaining a unified organizational account of biological functions. (shrink)
The human sentence processor is able to make rapid predictions about upcoming linguistic input. For example, upon hearing the verb eat, anticipatory eye-movements are launched toward edible objects in a visual scene. However, the cognitive mechanisms that underlie anticipation remain to be elucidated in ecologically valid contexts. Previous research has, in fact, mainly used clip-art scenes and object arrays, raising the possibility that anticipatory eye-movements are limited to displays containing a small number of objects in a visually impoverished context. In (...) Experiment 1, we confirm that anticipation effects occur in real-world scenes and investigate the mechanisms that underlie such anticipation. In particular, we demonstrate that real-world scenes provide contextual information that anticipation can draw on: When the target object is not present in the scene, participants infer and fixate regions that are contextually appropriate. Experiment 2 investigates whether such contextual inference requires the co-presence of the scene, or whether memory representations can be utilized instead. The same real-world scenes as in Experiment 1 are presented to participants, but the scene disappears before the sentence is heard. We find that anticipation occurs even when the screen is blank, including when contextual inference is required. We conclude that anticipatory language processing is able to draw upon global scene representations to make contextual inferences. These findings are compatible with theories assuming contextual guidance, but posit a challenge for theories assuming object-based visual indices. (shrink)
Dynamicism has provided cognitive science with important tools to understand some aspects of “how cognitive agents work” but the issue of “what makes something cognitive” has not been sufficiently addressed yet, and, we argue, the former will never be complete without the later. Behavioristic characterizations of cognitive properties are criticized in favor of an organizational approach focused on the internal dynamic relationships that constitute cognitive systems. A definition of cognition as adaptive-autonomy in the embodied and situated neurodynamic domain is provided: (...) the compensatory regulation of a web of stability dependencies between sensorimotor structures, is created and preserved during a historical/developmental process. We highlight the functional role of emotional embodiment: internal bioregulatory processes coupled to the formation and adaptive regulation of neurodynamic autonomy. Finally, we discuss a “minimally cognitive behavior program” in evolutionary simulation modelling suggesting that much is to be learned from a complementary “minimally cognitive organization program”.

Justifying his proposal for “health savings accounts,” which would allow individuals to set aside tax-free dollars against future healthcare needs, President Bush has said that “Health savings accounts all aim at empowering people to make decisions for themselves.” Who could disagree with such a sentiment? Although bioethicists may be among those who express skepticism that personal health savings accounts will be part of the needed “fix” of our healthcare financing system, self determination has long been part of their mantra. Indeed, (...) the field of bioethics played an important role in advancing this idea in the medical world when physician paternalism was regnant. Has its popularity caused it to become so vapid as to be ripe for misuse? (shrink)
There is consensus that children have questionable decisional capacity and, therefore, in general a parent or a guardian must give permission to enroll a child in a research study. Moreover, freedom from duress and coercion, the cardinal rule in research involving adults, is even more important for children. This principle is embodied prominently in the Nuremberg Code (1947) and is embodied in various federal human research protection regulations. In a program named "SATURN" (Student Athletic Testing Using Random Notification), each school (...) in the Oregon public-school system may implement a mandatory drug-testing program for high school student athletes. A prospective study to identify drug use among student-athletes, SATURN is designed both to evaluate the influence of random drug testing and to validate the survey data through identification of individuals who do not report drug use. The enrollment of students in the drug-testing study is a requirement for playing a school sport. In addition to the coercive nature of this study design, there were ethically questionable practices in recruitment, informed consent, and confidentiality. This article concerns the question of whether research can be conducted with high school students in conjunction with a mandatory drug-testing program, while adhering to prevailing ethical standards regarding human-subjects research and specifically the participation of children in research.

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.

The author reminds us in his Introduction that a phenomenological examina- tion of intersubjectivity is guided by a "twofold critical design". Against sociologism, which stresses the primacy of the We-relationship, so that the irreducible sense-bestowing function of the ego is overlooked, and against psychologism, which ignores a "subjectual" dimension that stands open to objectivity, Moreno M~irquez attempts to throw light on "the essential nexus between egological subjectivity, transcendental intersubjectivity and dialogical praxis, and on the other hand the possibilities of (...) ontological openness and sense-bestowing" (p. 24). In view of various criticisms raised against Husserl's theory, he points out that its primary concern was the cooperation between subjects aimed at the emergence of objectivity, and delimits his subject matter so that the unifying thread among the diverse topics covered is the "ontological competence" of transcendental intersub- jectivity.

This paper aims to provide a philosophical and theoretical account of biological communication grounded in the notion of organisation. The organisational approach characterises living systems as organised in such a way that they are capable to self-produce and self-maintain while in constant interaction with the environment. To apply this theoretical framework to the study of biological communication, we focus on a specific approach, based on the notion of influence, according to which communication takes place when a signal emitted by a (...) sender triggers a change in the behaviour of the receiver that is functional for the sender itself. We critically analyse the current formulations of this account, that interpret what is functional for the sender in terms of evolutionary adaptations. Specifically, the adoption of this etiological functional framework may lead to the exclusion of several phenomena usually studied as instances of communication, and possibly even of entire fields of investigation such as synthetic biology. As an alternative, we reframe the influence approach in organisational terms, characterising functions in terms of contributions to the current organisation of a biological system. We develop a theoretical account of biological communication in which communicative functions are distinguished from other types of biological functions described by the organisational account (e.g. metabolic, ecological, etc.). The resulting organisational-influence approach allows to carry out causal analyses of current instances of phenomena of communication, without the need to provide etiological explanations. In such a way it makes it possible to understand in terms of communication those phenomena which realise interactive patterns typical of signalling interactions – and are usually studied as such in scientific practice – despite not being the result of evolutionary adaptations. Moreover, this approach provides operational tools to design and study communicative interactions in experimental fields such as synthetic biology. (shrink)
It has been a pleasure to read these papers and to contemplate their importance for what I believe to be a useful and provocative prism though which to view the field of bioethics: the nature of moral consensus. In my own most extended contribution to this literature, DecidingTogether, I did not attempt to prescribe so much as to understand the role of moral consensus in the practice of bioethics. At the end of the book, I expressed the hope that it (...) might help trigger an examination of bioethics and moral consensus. Though a few others shared my interest at that time (in particular Tris Engelhardt, for whose early encouragement I remain deeply grateful), with this set of stimulating papers the conversation has finally begun in earnest.

In this paper we address the question of minimal cognition by investigating the origin of some crucial cognitive properties from the very basic organisation of biological systems. More specifically, we propose a theoretical model of how a system can distinguish between specific features of its interaction with the environment, which is a fundamental requirement for the emergence of minimal forms of cognition. We argue that the appearance of this capacity is grounded in the molecular domain, and originates from basic mechanisms (...) of biological regulation. In doing so, our aim is to provide a theoretical account that can also work as a possible conceptual bridge between Synthetic Biology and Artificial Intelligence. In fact, we argue, Synthetic Biology can contribute to the study of minimal cognition, by providing a privileged approach to the study of these mechanisms by means of artificial systems. (shrink)
This paper aims to propose a version of the description theory of reference –for short, descriptivism– on natural kind terms. This version is grounded on some proposals of descriptivists, such as Searle and Strawson, about proper names, which will be extended to natural kind terms. According to Searle and Strawson the reference of a proper name is determined by a sufficient number of the descriptions that speakers associate with the name, but among the sorts of descriptions admitted by these authors (...) are those in which the average speaker defers the reference of a term to other speakers. In this regard, descriptivism can accept Putnam’s thesis of the division of linguistic labour and claim that some of the descriptions associated by non-experts have the function of deferring the reference of natural kind terms to their reference in the use by experts. Thus, descriptivism can maintain that the reference of a natural kind term is determined by a sufficient number of the descriptions that experts concerning a natural kind associate with the term. I will argue that this version of descriptivism, which grants more weight to social links than to historical links, can explain better than Kripke’s theory the reference of the use of natural kind terms by the average speaker.

In recent years, streaming music platforms have become very popular mainly due to the huge number of songs these systems make available to users. This enormous availability means that recommendation mechanisms that help users to select the music they like need to be incorporated. However, developing reliable recommender systems in the music field involves dealing with many problems, some of which are generic and widely studied in the literature while others are specific to this application domain and are therefore less (...) well-known. This work is focused on two important issues that have not received much attention: managing gray-sheep users and obtaining implicit ratings. The first one is usually addressed by resorting to content information that is often difficult to obtain. The other drawback is related to the sparsity problem that arises when there are obstacles to gather explicit ratings. In this work, the referred shortcomings are addressed by means of a recommendation approach based on the users’ streaming sessions. The method is aimed at managing the well-known power-law probability distribution representing the listening behavior of users. This proposal improves the recommendation reliability of collaborative filtering methods while reducing the complexity of the procedures used so far to deal with the gray-sheep problem. (shrink)
We argue that the transition from unicellular to multicellular systems raises important conceptual challenges for understanding agency. We compare several MC systems displaying different forms of collective behavior, and we analyze whether these actions can be considered organismically integrated and attributable to the whole. We distinguish between a ‘constitutive’ and an ‘interactive’ dimension of organizational complexity, and we argue that MC agency requires a radical entanglement between the related processes which we call “the constitutive-interactive closure principle”. We explain in detail (...) that this is not possible without a regulatory center functionally integrating the two dimensions, and we also argue that, in turn, this type of regulation would not be possible without a special type of organization between the cells required for the development and maintenance of systems capable of integrated behavior.

Western society today is less unified by a set of core values than ever before. Undoubtedly, the concept of moral consensus is a difficult one in a liberal, democratic and pluralistic society. But it is imperative to avoid a rigid majoritarianism where sensitive personal values are at stake, as in bioethics. Bioethics has become an influential part of public and professional discussions of health care. It has helped frame issues of moral values and medicine as part of a more general (...) effort to find consensus about some of the most perplexing questions of our time. But why is it thought that a moral consensus is important or that it deserves respect? How does moral consensus acquire legitimacy in a society that includes diverse value systems? How is moral consensus possible and how do small groups help create or distort consensus processes? Written by a medical school professor trained in philosophy, this timely work tackles these questions from philosophical, historical, and social scientific standpoints. It begins by describing the traditional ambivalence about consensus in Western culture as well as the uncertain relationship in modernity between consensus and expertise. After outlining the current bioethical consensus, the book gives philosophical and political analyses of the idea of consensus, then assesses the role of consensus in national ethics commissions and in the ethics committee movement. Moreno constructs an original, naturalistic philosophy of moral consensus, referred to as "bioethical naturalism", and then applies sociology and social psychology to actual consensus processes. The book concludes with an account of bioethics as a consensus-oriented social reform movement. This insightful volume will be essential reading for bioethicists, philosophers, physicians, members of ethics committees, and all those concerned with ethical and social issues in health care.
