Whereas boson coherent states with complex parametrization provide an elegant, and intuitive representation, there is no counterpart for fermions using complex parametrization. However, a complex parametrization provides a valuable way to describe amplitude and phase of a coherent beam. Thus we pose the question of whether a fermionic beam can be described, even approximately, by a complex-parametrized coherent state and define, in a natural way, approximate complex-parametrized fermion coherent states. Then we identify four appealing properties of boson coherent states (eigenstate (...) of annihilation operator, displaced vacuum state, preservation of product states under linear coupling, and factorization of correlators) and show that these approximate complex fermion coherent states fail all four criteria. The inapplicability of complex parametrization supports the use of Grassman algebras as an appropriate alternative. (shrink)

Postdisciplinary Knowledge is the first book to articulate postdisciplinarity in philosophical, theoretical and methodological terms, helping to establish it as an important intellectual movement of the 21st century. It formulates what postdisciplinarity is, and how it can be implemented in research practice. The diverse chapters present a rich collection of highly creative thought-provoking essays and methodological insights. Written by a number of pioneering intellectuals with a range of backgrounds and research foci, these chapters cover a broad spectrum of areas demonstrating (...) alternative ways of producing knowledge. Essays are interspersed with dialogue, encouraging a comprehensive and engaging discussion on this emerging movement. Not limited to a specific field or discipline, this will be of great interest to upper level students and researchers in a wide range of subject areas, including: tourism, sociology, education, psychology, physiotherapy, fine arts, architecture and design, as well as those with a general interest in epistemology and methodology.

Explores and articulates Jean-Luc Nancy's profound impact on our understanding of artistic and literary modernism.

In Heraclitus’ time, thymos and psyche carried highly similar or even identical meanings, because both could refer to life, courage, personality, emotions, and reason. Heraclitus probably worked with all of these meanings. He may have been partly inspired by Homer and post-Homeric literature, where the two terms were likewise placed side by side and often used interchangeably. In Heraclitus, thymos and psyche are not opposites in terms of signification. Oftentimes, they can be “swapped,” and their meaning and “costs” exchanged. The (...) source and cause of this special exchange is desiring or wanting (thelein), which connects all these senses but is also the source of conflict and fighting. Desire—regardless of what it is and what is desired—is simultaneously the acquisition of the desired object or person and a way of paying for it. This struggle for the desired object is difficult not only because of its consequences (the price), but also because it is not possible to permanently stop desiring, which is why this struggle cannot be brought to an end.

Las 15 piezas que ahora lo conforman abrevan en la Historia, en confeciones personales y entrevistas, y mezclan la literatura y el periodismo de manera audaz y perfecta. Los protagonistas son hombres excepcionales y el momento que se ha elegido para contar son las visperas de sus muertes -tal vez el momento de mayor soledad y de mayor intimidad de un hombre. A traves de la magistral escritura de Tomas Eloy Martinez tenemos el privilegio de asistir a los ultimos minutos (...) de sus vidas, el momento previo a perderlo todo y cuando, resistiendo a la indiferencia del mundo, se suena con alguna inmortalidad.

The most prominent Czech philosopher, Karel Kosík, makes a few hints to the Vienna Circle, Otto Neurath and "positivism" in his important book, DIALECTICS OF THE CONCRETE (1963). I mine these few remarks for a better understanding of the conflicts, as well as connections, between the social progressivism of the Vienna Circle and the later Marxist humanism.

Modalists think that knowledge requires forming your belief in a “modally stable” way: using a method that wouldn't easily go wrong, or using a method that wouldn't have given you this belief had it been false. Recent Modalist projects from Justin Clarke-Doane and Dan Baras defend a principle they call “Modal Security,” roughly: if evidence undermines your belief, then it must give you a reason to doubt the safety or sensitivity of your belief. Another recent Modalist project from Carlotta Pavese (...) and Bob Beddor defends “Modal Virtue Epistemology”: knowledge is a belief that is maximally modally robust across “normal” worlds. We'll offer new objections to these recent Modalist projects. We will then argue for a rival view, Explanationism: knowing something is believing it because it's true. We will show how Explanationism offers a better account of undermining defeaters than Modalism, and a better account of knowledge. (shrink)

Many philosophers believe that our ordinary English words man and woman are “gender terms,” and gender is distinct from biological sex. That is, they believe womanhood and manhood are not defined even partly by biological sex. This sex/gender distinction is one of the most influential ideas of the twentieth century on the broader culture, both popular and academic. Less well known are the reasons to think it’s true. My interest in this paper is to show that, upon investigation, the arguments (...) for the sex/gender distinction have feet of clay. In fact, they all fail. We will survey the literature and tour arguments in favor of the sex/gender distinction, and then we’ll critically evaluate those arguments. We’ll consider the argument from resisting biological determinism, the argument from biologically intersex people and vagueness, the argument from the normativity of gender, and some arguments from thought experiments. We’ll see that these arguments are not up to the task of supporting the sex/gender distinction; they simply don’t work. So, philosophers should either develop stronger arguments for the sex/gender distinction, or cultivate a variety of feminism that’s consistent with the traditional, biologically-based definitions of woman and man.

Many contemporary epistemologists hold that a subject S’s true belief that p counts as knowledge only if S’s belief that p is also, in some important sense, safe. I describe accounts of this safety condition from John Hawthorne, Duncan Pritchard, and Ernest Sosa. There have been three counterexamples to safety proposed in the recent literature, from Comesaña, Neta and Rohrbaugh, and Kelp. I explain why all three proposals fail: each moves fallaciously from the fact that S was at epistemic risk (...) just before forming her belief to the conclusion that S’s belief was formed unsafely. In light of lessons from their failure, I provide a new and successful counterexample to the safety condition on knowledge. It follows, then, that knowledge need not be safe. Safety at a time depends counterfactually on what would likely happen at that time or soon after in a way that knowledge does not. I close by considering one objection concerning higher-order safety.

Do the facts of evolution generate an epistemic challenge to moral realism? Some think so, and many “evolutionary debunking arguments” have been discussed in the recent literature. But they are all murky right where it counts most: exactly which epistemic principle is meant to take us from evolutionary considerations to the skeptical conclusion? Here, I will identify several distinct species of evolutionary debunking argument in the literature, each one of which relies on a distinct epistemic principle. Drawing on recent work (...) in epistemology, I will show that most of these initially plausible principles are false, spoiling the arguments that rely on them. And we will see that each argument threatens only one popular view of moral psychology: a “Representationalist” view on which our moral judgments rely crucially on a mental intermediary—e.g. a sentiment, gut reaction, or affect-laden intuition—delivered by our evolved moral faculty. In the end, only one evolutionary debunking argument remains a menace: an “ Argument from Symmetry ” that I will introduce to the literature. But we will see that it should worry only all naturalists, pressuring them into a trilemma: give up moral realism, accept a rationalism that is incongruous with naturalism, or give up naturalism. Non-naturalists are free and clear. (shrink)
