Among Benjamin Libet's experiments on the relationship between consciousness and neural activity, those pointing at a substantive difference between subjective timing of a sensory experience and the experimental measure of the time needed to produce that experience appear particularly interesting. From a subjective standpoint, one is immediately conscious of a sensory experience, whereas, as a result of objective measured time of reaction, unconscious neural activation in the presence of a sensory stimulus begins 500 msec before one being aware of the (...) stimulus. In order to compensate this discrepancy, Libet introduces the notion of antedating. However, there is no fully satisfactory answer to the question about the conditions of possibility for antedating. Therefore, the very notion of antedating is highly problematic, though not infertile: the paradoxes present in this conception foster a profound review of the meaning of our experience of time and of the relationships between objective and subjective time.

Politics is hugely complex. Some try to reduce its complexity by examining it through an ideological worldview, a one-size-fits-all prescriptive formula or a quantitative examination of as many 'facts' as possible. Yet politics cannot be adequately handled as if it were made of cells and particles: ideological views are oversimplifying and sometimes dangerous. Politics is not simply a moral matter, nor political philosophy a subdivision of moral philosophy. This book is devised as a basic conceptual lexicon for all those who (...) want to understand what politics is, how it works and how it changes or fails to change. Key concepts such as power, conflict, legitimacy and order are clearly defined and their interplay in the state, interstate and global level explored. Principles such as liberty, equality, justice and solidarity are discussed in the context of the political choices confronting us. This compact and systematic introduction to the categories needed to grasp the fundamentals of politics will appeal to readers who want to gain a firmer grasp on the workings of politics, as well as to scholars and students of philosophy, political science and history.

Se trata de una reseña bibliográfica del libro de Guerrero, Luis Juan Que es la belleza y otros ensayos, Buenos Aires, Biblos.

This paper breaks with the sociological notion of ‘risk society’ and argues in favour of a philosophical view that sees the two planetary threats of late modernity, nuclear weapons and global warming, as ultimate challenges to morality and politics rather than risks that we can take and manage. The paper also raises the question of why we should feel responsible for the effects of these two global challenges on future generations and in this sense elaborates on the transgenerational chain of (...) parenthood rather than on considerations of justice.

In this paper we ask whether approximation for abstract argumentation is useful in practice, and in particular whether reasoning with grounded semantics – which has polynomial runtime – is already an approximation approach sufficient for several practical purposes. While it is clear from theoretical results that reasoning with grounded semantics is different from, for example, skeptical reasoning with preferred semantics, we investigate how significant this difference is in actual argumentation frameworks. As it turns out, in many graphs models, reasoning with (...) grounded semantics actually approximates reasoning with other semantics almost perfectly. An algorithm for grounded reasoning is thus a conceptually simple approximation algorithm that not only does not need a learning phase – like recent approaches – but also approximates well – in practice – several decision problems associated to other semantics.

En este texto se hace una brevísima reflexión en torno al quehacer filosófico como labor temporal ceñida al presente, el filosofar en su estructura fundamental ha de ser cuestionado desde lo local en razón a su temporalidad actual. Lo presentado es más que una apuesta, un alto en el camino para examinar las fuentes de la eventualidad y sus estructuras fundamentales.

La aportación filosófica de Arturo Andrés Roig abrevó de múltiples fuentes; en este artículo se ahonda en los antecedentes del concepto acuñado por Roig: “giro lingüístico”. Según el autor de este artículo, en la construcción de éste término confluyen tres ejes: el lingüístico (Bachtin/Volochinov), ..
