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.

This chapter argues for a notion of time that allows time travel. In order to time traveling to happen, in contrast to Presentism, the chapter demonstrates that we can change the past and we have some place where to travel. It shows the advantages of a non-presentist ontology that advocates for indeterminacy of future facts based not on its absence of truth-value, but on the overdetermination of future facts. The conclusion is that to break the causal chain is impossible in (...) we are placed in the same causal line. But if we rethink the time traveling as a trans-world traveling, it is possible to open a new causal line anytime that someone travel in time, to the past as well as to the future. (shrink)

ResumenPrimero, veremos el modo en que Dennett defiende su teoría de la conciencia frente a los ataques de destacados filósofos, logrando contrastar su anti-intuicionismo con las numerosas dificultades que se le presentan a todos aquellos que conciben la conciencia de modo realista. Segundo, afrontamos la explicación del uso de la evolución llevado a cabo por Dennett para explicar el nacimiento de la mente humana. Tercero, analizamos el importante papel que el lenguaje tiene en la aparición del pensamiento y el modo (...) en que ello permite el establecimiento de todo un entramado de simbología llamado cultura. Cuarto, nos detendremos en una matización y dos críticas al naturalismo dennettiano.Palabras clave:Daniel C. Dennett, conciencia, evolución, intencionalidadFirst, we show the Dennett’s theory of conciousness in a comparative and confrontative approach with the realistic conceptions of mind. Second, we confront the dennettian’s explanation of the human evolution. Third, we analyze the language’s rol in the appearance of thought and is implication in the culture. Fourth, we conclude with a elucidation and two critics of the dennettian naturalism.keywordsDaniel C. Dennett, conciousness, evolution, intentionality. (shrink)

According to Vázquez and Liz (Found Sci 16(4): 383–391, 2011), Points of View (PoV) can be considered in two different ways. On the one hand, they can be explained following the model of propositional attitudes. This model assumes that the internal structure of a PoV is constituted by a subject, a set of contents, and a set of relations between the subject and those contents. On the other hand, we can analyze points of view taking as a model the notions (...) of location and access. If we choose to follow the second approach, instead of the first one, the internal structure of a PoV is not directly addressed, and the emphasized features of PoV are related to the function that PoV are intended to have. That is, PoV are directly identified by their role and they can solely be understood as ways of accessing the world that bring some kind of perspective about it. Having this in mind, we would like to propose a notation that explains how to understand such access as a sort of models (that can allow the creation of concepts), independently of whether the precise PoV under consideration is impersonal or non-impersonal, its kind of content, and its subjective or objective character. First, we will present an account of some previous approaches to the study of points of view. Then, we will analyze what kind of structure the world is assumed to posses and how the access to it is possible. Third, we will develop a notation that explains PoV as qualitative dimensions by means of which it is possible to valuate objects and states of the world. (shrink)
