This high-level study discusses Newtonian principles and 19th-century views on electrodynamics and the aether. Additional topics include Einstein's electrodynamics of moving bodies, Minkowski spacetime, gravitational geometry, time and causality, and other subjects. Highlights include a rich exposition of the elements of the special and general theories of relativity.

This paper is concerned with certain ontological issues in the foundations of geographic representation. It sets out what these basic issues are, describes the tools needed to deal with them, and draws some implications for a general theory of spatial representation. Our approach has ramifications in the domains of mereology, topology, and the theory of location, and the question of the interaction of these three domains within a unified spatial representation theory is addressed. In the final part we also consider (...) the idea of non-standard geographies, which may be associated with geography under a classical conception in the same sense in which non-standard logics are associated with classical logic.

Reasons-first theorists claim that facts about reasons for attitudes are normatively primitive, and that all other normative facts ultimately reduce to facts about reasons. According to their view, for example, the fact that something is good ultimately reduces to facts about reasons to favour it. I argue that these theories face a challenging dilemma due to the normativity of arational lifeforms, for instance the fact that water is good for plants. If all normative facts are, ultimately, facts about reasons for (...) attitudes, then reasons-first theorists must either (a) show that these facts do reduce to facts about reasons, or (b) concede that they do not and, instead, show that this is not a problem for their view. Both options, however, are riddled with difficulties—or so I will try to argue. (shrink)

El autor analiza algunos aspectos de los debates sobre la democracia en la llamada transición de los años ̓80, para advertir sobre la preeminencia que adquirieron las disposiciones procedimentales y representativas —elevadas a condición metanormativa— y la conceptualización de la política como producción de consensos. Esas orientaciones impidieron una recuperación de las experiencias democráticas que la dictadura intentó cancelar, y fueron incapaces de poner en foco las figuras de subjetividad que el terror estatal y el neoliberalismo produjeron en tanto intervenciones (...) sobre las tramas sociales. Finalmente, el autor se detiene brevemente en algunas experiencias políticas democratizadoras, en tanto formas de aparición de los pueblos en estos últimos 40 años. (shrink)

Husserl proceeds to show how a world-representation emerges from our world-experience, and how an idea of the world plays a role in the expansion of world-representations. He also draws our attention to the appropriation of other world-representations in a process of adjustment and compensation leading to intersubjective world-representations, and offers an analysis of the status of world-representations within transcendental phenomenology. In this article I will underline the relevance of Husserl’s concept of horizonedness to the characterization of the three levels of (...) world-experience, worldrepresentation, and the world as an idea. In getting clear on this relevance several points must be emphasized. (shrink)

Volume 1 of Politics, a work in constructive social theory. Newly available, the complete work of Politicsa program for a comprehensive progressive alternative to the dominant ideologies of social democracy and neo-liberalismfrom one of the worlds leading social and political thinkers. False necessity is the central theme in the three-volume series Politics. It presents both a way of explaining society and a program for changing it. The explanation develops a radical alternative to Marxism, showing how we can account for established (...) social arrangements without denying their contingency or our freedom. The program offers a progressive alternative to the now-dominant ideological conceptions of neoliberalism and social democracy: a set of institutional innovations that would democratize markets, deepen democracy and empower individuals. For this new edition, Unger has written a comprehensive introduction that explores the limits of our understanding of society and our practice of politics, and reconsiders proposals contained in the book as special cases of a larger family of untried political possibilities.

The present investigation aims to elucidate the presence of myth in the work of Eduardo Nicol. This inquiry of course, is something not thought about, since the author in question from the beginning of his philosophy has recognized that the path of thought is beyond myth, that is, it is nuanced by reason and by conceptual rigor. In other words, for him philosophy is about what is phenomenologically accessible and about what is rationally intelligible. Precisely for this reason, one of (...) the names with which Nicol's philosophy is known is under the name of "Metaphysics of expression" by virtue of the fact that what is given is commonly acquired through an expressive or communicative act. However, and despite this conceptual position, the fact is that the presence of myth can be found at the very heart of this philosopher’s philosophy. It should be noted that there is a particular myth that prevails in the clearing of his work, namely the myth of the androgyne. Through this myth it is possible to elucidate the origin of man and the original idea about symbol. (shrink)
