This book seeks to arrive at a better understanding of the relationships between the objective and subjective aspects of time. It discusses the existence of fluent time, a controversial concept in many areas, from philosophy to physics. Fluent time is understood as directional time with a past, a present and a future. We experience fluent time in our lives and we adopt a temporal perspective in our ways of knowing and acting. Nevertheless, the existence of fluent time has been debated (...) for both philosophical and scientific reasons, thus creating a rift between the subjective and objective aspects of time. Starting from the basic notion of points of view, or perspectives, this book explores the relationships between objective or external time, as it has been conceptualized by science, and subjective or internal time, which is involved in our lived experiences. It establishes a general framework encompassing the nature, structure and mode of existence of points of view, in which the objective and subjective aspects of time can be integrated. The book mainly addresses researchers and postgraduates in philosophy and logic. Additionally, it offers inspiration for physicists and computer scientists involved in the modeling and simulation of complex behaviors for which the representation of internal time should be considered together with the notion of objective, external time.

In contrast with the development of big theories in the context of social sciences, there is nowadays an increasing interest in the construction of simulation models for complex phenomena. Those simulation models suggest a certain image of social sciences as a kind of, let us say, "patchwork". In that image, an increase in understanding about the phenomena modeled is obtained through a certain sort of aggregation. There is not an application of sound, established theories to all the phenomena of a (...) certain kind, but an aggregation of the structures supposed, and of the results obtained, when particular systems are modeled. The recent case of the "El Farol Bar" problem, and the models built in order to face this problem, are a good example of this. We will analyze that case, trying to make clear what would be implied by the image above mentioned. Special attention will be paid to the need to take seriously the notion of a bounded rationality, linked to the special circumstances generating each decision problem, and to the existence of an irreducible pluralism of models.

Examinamos el marco de congruencia teórica del cambio de la fase sólida a la fase líquida de la modernidad sirviéndonos de una revisión de La rebelión de las masas interpretada desde el ilimitado entorno de relaciones comunicativas en la red. En su póstuma Retrotopía, Bauman propone la noción de vecindario indefinido como categoría explicativa de la aceleración en la red de las tendencias consumistas que caracterizaron el individualismo de la cultura de masas, estableciendo además una pauta de continuidad en la (...) reaparición de asociaciones tribales en el vecindario indefinido. Abordamos hermenéuticamente la interrelación entre vecindario indefinido y rebelión de masas. Si la apertura de la red a la comunicación cara a cara virtual exacerba las pautas consumistas y tribales del consumismo de la fase sólida, la rebelión orteguiana puede entenderse como fruto exacerbado del individualismo que nutre la propensión consumista del vecindario indefinido globalizado.

Nuestro principal objetivo en este trabajo es el de analizar si es posible construir sistemas lógicos temporales-epistémicos lo suficientemente satisfactorios. Sin embargo, las principales dificultades para lograr este propósito provienen del hecho de tener que combinar una perspectiva temporal absoluta con una perspectiva epistémica relativa a cada agente; es decir, por un lado, los instantes de tiempo vienen determinados desde el punto de vista de un observador situado fuera del mundo, y, por otro lado, las alternativas epistémicas de cada agente (...) son relativas a dicho agente. Pensamos que algunas de estas dificultades podrían ser superadas con la ayuda de las lógicas híbridas, puesto que este tipo de lógicas simplifica la combinación de sistemas temporales y epistémicos, y así podemos evitar tener que construir modelos excesivamente complicados. Our main goal in this paper is to analyse if it is possible to build some suitable Temporal-Epistemic Systems. However, the main difficulties in order to aim this goal come from the fact of having to combine an absolute temporal perspective with a relative epistemic perspective; that is, on one hand, temporal points are determined from the point of view of an observer placed outside the world, and, on the other hand, the epistemic alternatives of each agent are relative to that agent. We think that some of these difficulties could be solved with the help of hybrid logics, because this kind of logics simplifies the combination of temporal and epistemic systems, and so we can avoid building highly complicated models.

In this paper I analyze the temporal structures that are appropriate to study the notion of point of view. When we analyze the points of view and their structure, it seems clear that we must take into account the time t in which a point of view is attributed to a subject. A two-dimensional temporal logic which combines a modal dimension for possibilities and a temporal one for the flow of time, offers a clear view of the temporary location of (...) a point of view. In this logic, we have histories, thanks to the temporal dimension, and evaluation is in two indices, time and history. These stories can be seen as different scenarios, providing a clear advantage when applying to the analysis of the notion of point of view. The conclusion is that, in order to give a proper approach for the notion of point of view, all these aspects should be combined. (shrink)

In this paper, I analyze the "surprise exam paradox". I think that the paradox can be avoided and I am going to focus on three points: 1) A conflict arises between reasoning and the confidence in the person that makes the original statement. If we examine the situation by reasoning we conclude that the statement is not going to come true, because we trust the person that states it. However, if it is not possible to happen, it happens, and the (...) person told the truth; 2) There is a disjunction among the days of the week: “or it is the first day or it is the second day or … it is the last day” (or Monday or Tuesday or Wednesday or Thursday or Friday). If I still have not been given the exam by Friday, the only possible conclusion is that the exam will be given on Friday. On Thursday, however, thesituation is completely different; 3) It seems that this paradox is a case of contingent futures, which branching time logics usually solve. The truth-value of the sentences is only relative to the branch that takes place in the end. (shrink)

Time has a highly unstable place between the objective and the subjective. On the one side, there are very well known philosophical arguments trying to show that time has only a subjective reality, even that it is merely a subjective epiphenomenon. On the other side, we are compelled to take points of view as non dispensable elements of reality, at least of a reality capable of containing beings like us. And points of view offer a world of temporal entities existing (...) in an objective way. Moreover, points of view themselves appear to be temporal entities among other temporal entities. We analyse both aspects of time. Our main focus will be McTaggart’s arguments against the reality of a fluent time, what he called temporal series of kind A. We will distinguish three very different arguments in McTaggart works. We analyse them in detail. And we reject their conclusive character. Our final target is to maintain that there is a room for fluent time in what is internal to points of view but external to the subjects adopting those points of view. (shrink)

There are very few analyses of the structure of points of view. However, we can identify two general approaches. One of them assumes as a paradigm the structure of propositional attitudes. Here, points of view are understood as having an internal structure similar to the one we can find in propositional attitudes. The other approach is based on the notions of location and access. Here, the internal structure of points of view is not directly addressed. The features that are emphasised (...) are related with the role that points of view are intended to have. Points of view would be ways of having access to the world, and to ourselves, from certain emplacements. The paper has three parts. In the first one, we present these two approaches and some interesting developments inside each one of them. In the second one, we examine more closely the relationships between the two approaches. In the third part of the paper, we defend the non-reducible relational nature and modal character of points of view obtaining some conclusions. (shrink)

Prior's approach to time has been neglected by semanticists for several reasons. The main one, we believe, is the inability of Priorean tense logic to refer to times. The second one, is the inability to account for some important features of natural language such as temporal anaphora and the role of temporal constructions in discourse. Priorean tense logic has, however, one important advantage over other accounts: the internal perspective of time (due to its modal nature). This paper examines extensions of (...) Priorean tense logic in which reference to times is possible, focusing on the so-called hybrid temporal logic. We will outline some of its main features and analyze some of its philosophical implications. (shrink)

We propose an analysis of the notion of model as crucially related to the notion of point of view. A model in this sense would always suggest a certain way of looking at a real system, a certain way of thinking about it and a certain way of acting upon it. We focus on System Dynamics as a paradigmatic case with respect to many of the features and problems we can find in the field of modelling and simulation. We analyse (...) in detail some of those features. All of them would be present in many other cases of construction and use of models. Furthermore, they would support the thesis that a model can be fruitfully understood as offering a point of view capable of improving our own points of view over a certain system. The point of view offered by the model could include both non-conceptual and conceptual contents, it would have a complex structure and behaviour, and it would have direct consequences on the decisions made by the subjects adopting that point of view.

Scholars in the humanities and social sciences have turned to ethics to theorize politics in what seems to be an increasingly depoliticized age. Yet the move toward ethics has obscured the ongoing value of political responsibility and the vibrant life it represents as an effective response to power. Sounding the alarm for those who care about robust forms of civic engagement, this book fights for a new conception of political responsibility that meets the challenges of today's democratic practice. Antonio Y. (...) Vázquez-Arroyo forcefully argues against the notion that modern predicaments of power can only be addressed ethically or philosophically through pristine concepts that operate outside of the political realm. By returning to the political, the individual is reintroduced to the binding principles of participatory democracy and the burdens of acting and thinking as a member of a collective. Vázquez-Arroyo historicizes the ethical turn to better understand its ascendence and reworks Adorno's dialectic of responsibility to reassert the political in contemporary thought and theory.

The ‘black box’ in Stoic axiology refers to the mysterious connection between the input of Stoic deliberation (reasons generated by the value of indifferents) and the output (appropriate actions). In this paper, I peer into the black box by drawing an analogy between Stoic and Kantian axiology. The value and disvalue of indifferents is intrinsic, but conditional. An extrinsic condition on the value of a token indifferent is that one's selection of that indifferent is sanctioned by context-relative ethical principles. The (...) value of an indifferent that does not meet this condition is normatively silenced, such that it fails to constitute a reason for action. (shrink)

This thesis presents and criticizes Hilary Putnam's argument that mathematics is as empirical as science, in particular the argument that the switch from Euclidean geometry to Riemannian geometry as the approporiate geometry for physical space constituted an instance of revising mathematics as a result of observation. The thesis explains Putnam's views on mathematics as following from his theory of meaning and reference for natural kind terms. It is argued that Putnam's account of reference is unsuitable for mathematical terms and that (...) an "if-thenist" approach to mathematical knowledge is more fruitful. (shrink)

Cada uno de los capítulos que reúne este libro es una invitación a abrir la discusión sobre ética en el trabajo de campo etnográfico, en particular sobre el problema del «consentimiento informado». Algunas de las perspectivas son coincidentes con otras en cuanto a los temas y a la forma de abordarlos, pero otras veces están en franca contradicción. Sin embargo, los autores coinciden en que los dilemas éticos tienen que ver con la relación que en cada momento se establece y (...) que, por lo tanto, no hay soluciones universales, porque los intereses y los valores que orientan la relación entre las personas tampoco lo son. Pero el hecho de que los dilemas éticos sean contextuales y dependan de la relación que en cada caso se establece, no exime de la responsabilidad de plantearlos, sino al contrario: hay que señalarlos porque no se pueden anticipar y tampoco presuponer que están resueltos. Este ejercicio supone darle la vuelta a la tela del trabajo antropológico para ver las costuras, los remiendos y los errores, lo que implica una buena dosis de humildad y a veces un doloroso ejercicio de escarbar en la intimidad y dejar expuesto lo que normalmente se oculta.

This document describes the implementation of a conical tank control system using an adaptive neurofuzzy system. For implementation, an indirect approach is used where the controller is optimized using the model obtained during the plant identification carried out using data obtained during the system operation. Furthermore, implementation includes training of neuro fuzzy-systems and application to control a conical tank. Regarding plant identification, preliminary training takes place using data obtained for different input values. The controller configuration is established considering the analogy (...) with a discrete-time linear system. The simulation shows that the control system manages to approach the desired response given by the considered reference model. (shrink)

This Element offers a systematic outline of ancient conceptions and uses of suspension of belief (understood broadly) while engaging with contemporary philosophy. It discusses the notion of epochē ('suspension of judgement') and other related terms, like aporia, aphasia, paradox, hypothesis, agnosticism, and Socratic wisdom. It examines the Academic and Pyrrhonian sceptics and some of their arguments and strategies for suspension. It also includes the use and conditions for suspension of belief in other philosophers like Socrates, Plato, Aristotle, the Stoics, Plotinus, (...) Protagoras, and Democritus. The Element is divided into four thematic sections, each addressing one of the following questions: What is suspension of belief? When does it arise? What could its scope be? And what are its practical and moral implications? (shrink)

Advocates of interactionism in the ethical criticism of art argue that ethical value impacts aesthetic value. The debate is concerned with “the intrinsic question”: the question of whether ethical flaws/merits in artworks’ manifested attitudes affect their aesthetic value (Gaut 2007: 9). This paper argues that the assumption that artworks have intrinsic ethical value is problematic at least in regards to a significant subset of works: fictional artworks. I argue that, insofar as their ethical value emerges only from attitudes attributable to (...) actual agents, fictional artworks only have extrinsic ethical value. I show that what is at stake for interactionism is whether ethical judgements concerning artists’ attitudes in a context, rather than manifested attitudes, are ever aesthetically relevant. I conclude that, without buying into extreme actual intentionalism, a still controversial theory of interpretation that ties artworks’ meaning to actual artists, interactionism fails to show that ethical flaws/merits are aesthetic flaws/merits.
