In this note, the problem of tracking random references and rejecting random perturbations in a quadrotor, both generated by an auxiliary system named exosystem, is solved by extending the deterministic tracking problem to the area of stochastic processes. Besides, it is considered that only a part of the state vector of the quadrotor is available through measurements. As a consequence, the state vector of the plant must be estimated in order to close the control loop. On this basis, a controller (...) to track random references and to reject random perturbations is developed by combining a Kalman filter to estimate the references and perturbations of an exosystem and an observer to estimate the states of a quadrotor. Besides, to obtain a more practical controller, the analysis is carried out in discrete time. Numerical simulations are used in a quadrotor to confirm the validity and effectiveness of the proposed control. (shrink)

We may succed in the fulfilment of our desires but still fail to properly own our practical life, perhaps because we acted as addicts, driven by desires that are alien to our will, or as “wantons,” satisfying the desires that we simply happen to have (Frankfurt, 1988 ). May we equally fail to own the outcomes of our epistemic life? If so, how may we attain epistemic ownership over it? This paper explores the structural parallellism between practical and epistemic rationality, (...) building on Williamson’s ( 2002 ) suggestion that we should commence with successful performances as the foundation for both domains, be it action or knowledge. By highlighting the limitations of higher-order regulative approaches in epistemology, exemplified by Sosa ( 2007, 2011, 2015, 2021 ), the paper introduces a form of teleological epistemic constitutivism inspired by Velleman ( 2000, 2009 ). The proposal is that epistemic ownership is not attained in the mere pursuit of truth or knowledge, but requires furthermore a struggle to understand what we know. (shrink)

There is a shared feeling among those familiar with pragmatism that, if applied in practice, the teachings of Peirce, James, Dewey, and their heirs could prove extraordinarily helpful in our current uncertain times—times of persistent moral disagreements and almost irreparable social conflicts. But to what extent is this feeling justified? What is the nature of these infelicitous circumstances? And, what makes pragmatism such a suitable approach? In this article, I claim that the main reason behind the ineffectiveness with which we (...) have traditionally addressed our differences is the uncritical acceptance and enactment of a pernicious dichotomy between objectivism and subjectivism. As I argue, it is pragmatist philosophers who most clearly understood the urgency to find an alternative to these extreme positions and who most successfully accomplished this task; it is to them, I claim, we must now turn if we are to more effectively address our disagreements and conflicts.

Jürgen Habermas’s discourse ethics is a method of intersubjective argumentation conceived to test the validity of moral norms on the basis of their universalizability. As some scholars have argued, Habermas’s proposal is problematic in that the process of argumentation is always affected by the circumstances of inequality and unfairness that pervade communal life and, therefore, it cannot be as inclusive and egalitarian as it needs to be in order to function effectively. In this paper, I argue that the solutions proposed (...) by these scholars, namely, the improvement of social conditions and the pluralization of the process of argumentation, cannot by themselves resolve the practical limitation Habermas’s method presents. As an alternative, I adopt Philip Kitcher’s approach to ethics according to which the establishment of moral norms is oriented not to the resolution of disagreements but to the restitution of healthy relationships among individuals. On the basis of this alternative conception, I propose the addition to Habermas’s principle of universalization of a supplemental criterion of moral justification—one that makes the validity of norms dependent upon their potential to foster altruism.

This paper analyses the metaliterary statements that pervade the oeuvre of Ennodius of Pavia (a.d. 474–521) in order to reconstruct his underlying conception of language: its nature, power, function, limitations, and dangers. This new perspective provides a more nuanced insight into the paradoxical poetics of the author as well as his final renunciation to literature after his appointment as bishop of Pavia.

In lieu of an abstract, here is a brief excerpt of the content:The Phenomenology of Superstition or a Phenomenological Superstition?Elena Ibáñez-Guerra (bio)KeywordsBehaviorism, constructionism, intentionality, operant behaviorWhen the editors of Philosophy, Psychiatry, & Psychology asked me to make some brief comments on two articles for the special issue edited by Pérez-Álvarez and Sass, I was delighted to accept, thinking that the task would be a straightforward one, and that I could easily meet the agreed deadline. But nothing could be further from (...) the truth. The articles were of such density and their content of such profundity that it took months of interpretation and study, and of bringing my own knowledge up to date, before I was in a position to understand the concepts, adjust my beliefs, and make some comments. I could certainly have delivered some kind of eulogy about the brilliance of their content; I might have countered with my own article. However, what seemed most coherent to me was to meet their arguments head on and deal with what I consider to be their principal weaknesses, leaving the bouquets for the end.The articles set out, as I understand them and within the clinical context, to relate phenomenology, in its most traditional form, with the most current form of Skinnerian behaviorism, situating themselves in a contextualism that is, at the same time, close to and removed from the most radical type of social constructionism.But let us begin by looking more closely at “Phenomenology and Behaviorism.” It is novel for me, though Professor Pérez-Álvarez had already proposed it several years ago (Pérez-Álvarez 1992), to view operant behavior as intentionality, or at least as involving final causality according to the Aristotelian classification. It is a surprising contention, not least because, as I recall, Skinner lived in a time and a context (historical reason) in which the basic goal of psychology was to convert itself into a natural science, comparable in all respects to physics, which it took as a model, focusing therefore on efficient causality (also according to Aristotle’s terminology), so that behavior was considered as the immediate consequence of a stimulus, and the stimulus–response association became the cornerstone of the discipline. It is true that the operant behavior concept refers to the functional relationship between behavior and reinforcement, but it is no less true that Skinner’s definition of reinforcement is totally empirical—“all that which increases or decreases the probability”—meaning that reinforcement can be considered neither as a motive nor as a reason for behavior, unless it be in the eyes of the observer. [End Page 251]Furthermore, even though Yela (1987) refers to Ortega y Gasset’s formula “I am myself and my circumstances” as a Skinnerian approach, the truth is that Yela himself argues that it is precisely the self that constitutes personality, such that I have a personality because I am me, and not vice versa, as Skinner would appear to argue. In this regard, Ortega’s celebrated formula has generally been interpreted, from the most personalist perspectives, as “the circumstances are myself”—to highlight the denial of the psychological subject by radical behaviorism (Mischel’s [1968] criticism of the concept of personality is relevant here). On top of this, Skinner’s rejection of all that was not directly observable, or at least, that could not be operationalized, calls into question the admissibility of anything called final cause or intentionality of behavior. In his philosophy, all the indications are that contingencies are what determine behavior; and that there would be no room for a structural causality, as Althusser would argue, or of a reciprocal determinism, in Bandura’s terms, or even of an interaction between subject and environment, as modern interactionists would maintain. “I am myself and my circumstances” seems in Skinner to become “the circumstances are me”, and indeed, the reinforcement history – which in the article in question is considered as something akin to the Sartrian idea of “life project” – is for Skinner nothing more than a continuous association of events. In my view, Ortega’s perspectivism would perhaps be closer to the sociology of the American action theorists, Merton, Parsons, etc., than to Skinnerian behaviorism, since “action”—as the action theorists...

La información masiva sobre los casos Garzón se ha caracterizado por la confusión, no siempre desinteresada, de los tres supuestos objeto de las querellas. Esto, a juicio del autor, obliga a individualizarlos cuidadosamente y a hacer lo mismo con las vicisitudes de cada una de las causas.

Savulescu and Cameron supported selectively locking down the elderly during the COVID-19 pandemic on two grounds: first, that preserving total lockdown would entail levelling down and, second, that levelling down is wrong. Their first assumption has been thoroughly addressed, but more can be said about their wider antiegalitarian point that levelling down is simply wrong. Egalitarians are not defenceless against the levelling-down objection. Even though some consider it the most serious challenge to supporters of equality, egalitarianism possesses sound reasons to (...) assert, not only that something valuable is preserved when we level down, but also that preserving it may be, in certain circumstances, preferable to pursuing other fundamental moral goals. Although troublesome from a well-being maximising standpoint, levelling down ensures that healthcare policy reflects a commitment with the idea that people are equal in moral worth. That commitment is important enough to trump certain improvements in individual well-being. In the case of pandemic lockdowns, not all the interests protected by free movement are as fundamental as to pursue them at the cost of equality. Savulescu and Cameron’s framework is so reliant on the view that levelling down is wrong that it fails to account for the valuable loss that having the elderly suffer alone represents. (shrink)

La inteligencia artificial transforma el derecho. No es solo un modo de facilitar la actividad jurídica. Tiene implicaciones epistemológicas y sociales. El derecho se reduce a datos y a cálculos. Prospera un jurista maquinal. Se empobrece la racionalidad jurídica. Se olvida que la clave del derecho no es el procesamiento de datos sino la creación de sentido.

Taking into account the difficulties that all attempts at a solution of the problem of causal-explanatory exclusion have experienced, we analyze in this paper the chances that mind-body causation is a case of overdetermination, a line of attack that has scarcely been explored. Our conclusion is that claiming that behaviors are causally overdetermined cannot solve the problem of causal-explanatory exclusion. The reason is the problem of massive coincidence, that can only be avoided by establishing a relation between mind and body; (...) that is, by denying overdetermination. The only way to defend that mind-body causation is a case of overdetermination would be by denying any modal force whatever to the principle of the causal closure of the physical, and this is a claim we would not like to reject.

In their recent book Radicalizing Enactivism. Basic minds without content, Dan Hutto and Erik Myin make two important criticisms of what they call autopoietic enactivism. These two criticisms are that AE harbours tacit representationalists commitments and that it has too liberal a conception of cognition. Taking the latter claim as its main focus, this paper explores the theoretical underpinnings of AE in order to tease out how it might respond to H&M. In so doing it uncovers some reasons which not (...) only appear to warrant H&M’s initial claims but also seem to point to further uneasy tensions within the AE framework. The paper goes beyond H&M by tracing the roots of these criticisms and apparent tensions to phenomenology and the role it plays in AE’s distinctive conception of strong life-mind continuity. It is highlighted that this phenomenological dimension of AE contains certain unexamined anthropomorphic and anthropogenic leanings which do not sit comfortably within its wider commitment to life-mind continuity. In light of this analysis it is suggested that AE will do well to rethink this role or ultimately run the risk of remaining theoretically unstable. The paper aims to contribute to the ongoing theoretical development of AE by highlighting potential internal tensions within its framework which need to be addressed in order for it to continue to evolve as a coherent paradigm.

Texto correspondiente a la defensa de la Tesis Doctoral del autor, que lleva por título La escuela jurídica kantiana y la ciencia del derecho en Alemania (1750-1804), en la que se examina el desenvolvimiento coherente del iusnaturalismo inmanentista alemán, a lo largo del periodo ilustrado, en su apelación a la ciencia jurídica (Rechtslehre), por medio de los conceptos a priori de naturaleza e historia.

AI systems are bringing an augmentation of human capabilities to shape the world. They may also drag a replacement of human conscience in large chunks of life. AI systems can be designed to leave moral control in human hands, to obstruct or diminish that moral control, or even to prevent it, replacing human morality with pre-packaged or developed ‘solutions’ by the ‘intelligent’ machine itself. Artificial Intelligent systems (AIS) are increasingly being used in multiple applications and receiving more attention from the (...) public and private organisations. The purpose of this article is to offer a mapping of the technological architectures that support AIS, under the specific focus of the moral agency. Through a literature research and reflection process, the following areas are covered: a brief introduction and review of the literature on the topic of moral agency; an analysis using the BDI logic model (Bratman 1987); an elemental review of artificial ‘reasoning’ architectures in AIS; the influence of the data input and the data quality; AI systems’ positioning in decision support and decision making scenarios; and finally, some conclusions are offered about regarding the potential loss of moral control by humans due to AIS. This article contributes to the field of Ethics and Artificial Intelligence by providing a discussion for developers and researchers to understand how and under what circumstances the ‘human subject’ may, totally or partially, lose moral control and ownership over AI technologies. The topic is relevant because AIS often are not single machines but complex networks of machines that feed information and decisions into each other and to human operators. The detailed traceability of input-process-output at each node of the network is essential for it to remain within the field of moral agency. Moral agency is then at the basis of our system of legal responsibility, and social approval is unlikely to be obtained for entrusting important functions to complex systems under which no moral agency can be identified.

Grit, which is originally conceptualized as passion and perseverance for long-term goals, has been associated with optimal performance. Although previous meta-analytic and systematic reviews summarized how grit relates to performance outcomes, they possess considerable shortcomings, such as (a) absence of summary on the association of grit with well-being outcomes; (b) absence of discussion on social, psychological, and emotional mechanisms linking grit to well-being; and (c) lack of elaboration on how alternative models can resolve fundamental problems in the grit construct. This (...) integrative review provides a comprehensive summary on the link of grit to performance and well-being outcomes. Importantly, it elaborates how alternative models can potentially address flaws in the existing grit theory. Future research directions are discussed on how to move forward the science of grit.

In this paper, an attempt is made to solve various problems posed to current theories of verisimilitude: the problem of linguistic variance; the problem of which are the best scientific methods for getting the most verisimilar theories; and the question of the ontological commitment in scientific theories. As a result of my solution to these problems, and with the help of other considerations of epistemological character, I conclude that the notion of 'Tarskian truth' is dispensable in a rational interpretation of (...) the scientific enterprise. As a logical result, however, falsificationism will be vindicated. (shrink)
