When I moved into the Tenderloin district of San Francisco, I immediately noticed the epidemic of homelessness that seemed to blanket the entire neighborhood. Even more prevalent was the problem of drug abuse and alcoholism. It would truly be safe to say that 70-80% of the neighborhood's occupants fall into this category. In my experience, San Francisco has the largest number of homeless people as compared to other cities I have visited. I do realize there are locales such (...) as Detroit, Chicago, and New York that have equal if not larger problems with homelessness, but since San Francisco is where I call home, it will be the focus of this project. People in the Tenderloin were pushing everything from street drugs like heroin and cocaine, to prescription pills like Oxycontin and Vicodin. There was almost no reaction to these activities by the local police, except perhaps to unjustly harass individuals that didn’t necessarily deserve it. It was almost as if the city created a way to deal with the problem by sectioning off the Tenderloin for the outcasts of society to "thrive" in. As long as they stayed out of the wealthy areas, there would be no need for the local government to intervene or develop a long term solution. These are the premises that inspired me. So in the spring of 2006, I walked the streets of the Tenderloin day and night so as to capture the essence of the area in the most realistic way. All images were shot with a 35 mm film camera. My intention in creating this book is one of enlightenment so that people of all backgrounds can see the completely ignored deterioration of nearly a dozen city blocks… Streets entirely cluttered with despair placed conveniently within a stone's throw of the streets where wealthy tourists shop for thousand dollar handbags and five-dollar coffees.

We explore the intimate connection between spacetime geometry and electrodynamics. This link is already implicit in the constitutive relations between the field strengths and excitations, which are an essential part of the axiomatic structure of electromagnetism, clearly formulated via integration theory and differential forms. We review the foundations of classical electromagnetism based on charge and magnetic flux conservation, the Lorentz force and the constitutive relations. These relations introduce the conformal part of the metric and allow the study of electrodynamics for (...) specific spacetime geometries. At the foundational level, we discuss the possibility of generalizing the vacuum constitutive relations, by relaxing the fixed conditions of homogeneity and isotropy, and by assuming that the symmetry properties of the electro-vacuum follow the spacetime isometries. The implications of this extension are briefly discussed in the context of the intimate connection between electromagnetism and the geometry of spacetime. (shrink)

The Schwarzschild solution has played a fundamental conceptual role in general relativity, and beyond, for instance, regarding event horizons, spacetime singularities and aspects of quantum field theory in curved spacetimes. However, one still encounters the existence of misconceptions and a certain ambiguity inherent in the Schwarzschild solution in the literature. By taking into account the point of view of an observer in the interior of the event horizon, one verifies that new conceptual difficulties arise. In this work, besides providing a (...) very brief pedagogical review, we further analyze the interior Schwarzschild black hole solution. Firstly, by deducing the interior metric by considering time-dependent metric coefficients, the interior region is analyzed without the prejudices inherited from the exterior geometry. We also pay close attention to several respective cosmological interpretations, and briefly address some of the difficulties associated to spacetime singularities. Secondly, we deduce the conserved quantities of null and timelike geodesics, and discuss several particular cases in some detail. Thirdly, we examine the Eddington–Finkelstein and Kruskal coordinates directly from the interior solution. In concluding, it is important to emphasize that the interior structure of realistic black holes has not been satisfactorily determined, and is still open to considerable debate. (shrink)

If Justice Louis Brandeis were alive to witness San Francisco’s recent experiment with universal health care legislation, he might amend his famous characterization of the states as “laboratories of democracy” to include municipalities as well. In San Francisco, where ten percent of residents have no health insurance and where fifteen percent of businesses provide no health coverage for their employees, the Board of Supervisors recently passed the San Francisco Health Care Security Ordinance, which funds a network of (...) primary care services for uninsured residents. While the Ordinance has, in the main, met with general approval, its provision mandating contributions from local businesses that do not meet minimum health spending requirements is the subject of ongoing litigation. The Ninth Circuit Court of Appeals recently ruled in the city’s favor, thereby allowing the spending provision to go forward pending a full appeal on the merits of the case. (shrink)

This is the first German volume for more than one century, dealing with the two main subjects that have dominated the present reception of the Spanish philosopher and theologian Francisco Suárez (1548-1617): metaphysics and law theory. The contributors discuss both Suárez as an influential thinker of modern European school metaphysics and as a representant of a global law philosophy and ethics. They also debate on the combination of theory and praxis in the light of the question which commitment a (...) universal First Philosophy could have today. The volume is complimented by an introduction to Suárez's works and vita, an overview and guide to recent primary and secondary literature, as well as a name register.--publlisher's desciption.

A translation of the Third and Fourth Disputations of Francisco Suárez.

_Dialectic and Dialogue_ seeks to define the method and the aims of Plato's dialectic in both the "inconclusive" dialogues and the dialogues that describe and practice a method of hypothesis. Departing from most treatments of Plato, Gonzalez argues that the philosophical knowledge at which dialectic aims is nonpropositional, practical, and reflexive. The result is a reassessment of how Plato understood the nature of philosophy.

This monograph presents new material on Francisco Suárez’s comprehensive theory of sense perception. The core theme is perceptual intentionality in Suárez’s theory of the senses, external and internal, as presented in his Commentaria una cum quaestionibus in libros Aristotelis De anima published in 1621. The author targets the question of the multistage genesis of perceptual acts by considering the ontological “items” involved in the procession of sensory information. However, the structural issue is not left aside, and the nature of (...) the relationship due to which our perceptions are mental representations of this or that object is also considered. The heuristic historiographical background includes not only the theories of classical authors, such as Aristotle and Aquinas, but also those of late medieval authors of the fourteenth century. These are headed by John Duns Scotus, John of Jandun, Peter Auriol and Peter John Olivi. Readers will discover the differences between Suárez’s and Aquinas’s views, as well as other sources that may have served as positive inspiration for the Jesuit’s theory. By considering the late medieval philosophy of the fourteenth century, this book helps, to a certain extent, to fill a gap in the historiography of philosophy regarding the link between late medieval and early modern scholasticism. In the first part of the book, the metaphysics of the soul and powers is considered. Chapters on the external senses follow, covering topics such as the sensible species, the causes of sensation, self-awareness, and the ordering of the external senses. A further chapter is devoted to the internal senses and the author argues that by reducing the number and functional scope of the interior senses Suárez deepens the gap between the external senses and the intellect, but he reduces it through emphasizing the unifying efficacy of the soul.This book brings a synthetic and unifying perspective to contemporary research and will particularly appeal to graduate students and researchers in theology and philosophy, especially philosophy of mind.

This book examines the human ability to participate in moments of joint feeling. It presents an answer to the question concerning the nature of our faculty to share in what might be called episodes of collective affective intentionality. The proposal develops the claim that our capacity to participate in such episodes is grounded in an ability central to our human condition: our capacity to care with one another about certain things. The author provides a phenomenologically adequate account of collective affective (...) intentionality that takes seriously the idea that feelings are at the core of our emotional relation to the world. He details a form of group emotional orientation that relies on the fact that the participating individuals have come to share a number of concerns. Readers will learn that at the heart of a collective affective intentional episode, one does not merely find a set of shared concerns, but also a particular mode of caring. In the end, the argument presented in this monograph makes plausible the idea that the emotions through which humans participate in moments of affective intentional community express our nature. In addition, it shows that the debate on collective affective intentionality also permits us to better understand the relationship between two conflicting philosophical pictures of ourselves: the idea that we are essentially social beings and the claim that we are creatures for whom our personal existence is an issue. Thus, aiming at an elucidation of the nature of our ability to feel together, the book offers a detailed account of what it is to situationally express our human nature by caring about something in a properly joint manner.

In this paper I draw on Einstein's distinction between “principle” and “constructive” theories to isolate two levels of physical theory that can be found in both classical and (special) relativistic physics. I then argue that when we focus on theoretical explanations in physics, i.e. explanations of physical laws, the two leading views on explanation, Salmon's “bottom-up” view and Kitcher's “top-down” view, accurately describe theoretical explanations for a given level of theory. I arrive at this conclusion through an analysis of explanations (...) of mass—energy equivalence in special relativity. (shrink)

Erick J. Ramirez, Miles Elliott and Per‑Erik Milam (2021) have recently claimed that using Virtual Reality (VR) as an educational nudge to promote empathy is unethical. These authors argue that the influence exerted on the participant through virtual simulation is based on the deception of making them believe that they are someone else when this is impossible. This makes the use of VR for empathy enhancement a manipulative strategy in itself. In this article, we show that Ramirez et al.’s ethical (...) rejection of empathy enhancement through VR is based on confusion. First, we show that this misunderstanding stems from the conception of empathy-enhancing simulations solely as failed attempts at “being someone else,” along with ignoring the crucial difference between the psychological perspective-taking processes of imagine-other and imagine-self. Then, having overcome that misconception, we argue that the ethical misgivings about the use of VR to promote empathy should disappear and that these projects have greater potential for behavioural change than purely sympathy-focused interventions.

This paper defends a ‘perspectivist’ reading of Plato’s dialogues. According to this reading, each dialogue presents a particular and limited perspective on the truth, conditioned by the specific context, aim and characters, where this perspective, not claiming to represent the whole truth on a topic, is not incompatible with the possibly very different perspectives found in other dialogues nor, on the other hand, can be subordinated or assimilated to one of these other perspectives. This model is contrasted to the other (...) models that have been proposed, i.e., Unitarianism, Developmentalism, and ‘Prolepticism’, and is shown to address and overcome the limitations of each. One major advantage of ‘perspectivism’ against the other interpretative models is that, unlike them, it can do full justice to the literary and dramatic character of the dialogues without falling into the opposite extreme of turning them into literary games with no positive philosophical content. To say that Plato’s dialogues are ‘perspectivist’ is not to say that they contain no ‘doctrines’ on the soul, for example, but, on the contrary, to stress the plurality of doctrines, with the observation that each is true within the limits of the argumentative function it is introduced to serve and of the specific dialogical context.

This essay explores Francisco Suárez’s account of the nature of human free will. To that end, Suárez’s engagement with John Calvin is considered so as to place the Jesuit’s account into greater relief. The conclusion of this study will reveal that, for Suárez, the human will’s freedom of self–determination is both caused by God and consists in its own indifference regarding the power to act and the power not to act.

Current mathematical models are notoriously unreliable in describing the time evolution of unexpected social phenomena, from financial crashes to revolution. Can such events be forecast? Can we compute probabilities about them? Can we model them? This book investigates and attempts to answer these questions through GOdel's two incompleteness theorems, and in doing so demonstrates how influential GOdel is in modern logical and mathematical thinking. Many mathematical models are applied to economics and social theory, while GOdel's theorems are able to predict (...) their limitations for more accurate analysis and understanding of national and international events. This unique discussion is written for graduate level mathematicians applying their research to the social sciences, including economics, social studies and philosophy, and also for formal logicians and philosophers of science.
