In the transition to Einstein’s theory of Special Relativity (SR), certain concepts that had previously been thought to be univocal or absolute properties of systems turn out not to be. For instance, mass bifurcates into (i) the relativistically invariant proper mass m0, and (ii) the mass relative to an inertial frame in which it is moving at a speed v = βc, its relative mass m, whose quantity is a factor γ = (1 – β2) -1/2 times the proper mass, (...) m = γm0.

Philosophers have constituted business ethics as a field by providing a systematic overview that interrelates its problems and concepts and that supplies the basis for building on attained results. Is there a properly theological task in business ethics? The religious/theological literature on business ethics falls into four classes: (1) the application of religious morality to business practices; (2) the use of encyclical teachings about capitalism; (3) the interpretation of business relations in agapa-istic terms; and (4) the critique of business from (...) a liberation theological point of view. Theologians have not adequately addressed the questions of whether there are particular theological tasks in the field as they define it, and whether, if they define it, the theological definition is different from the philosophical.

In Minkowski spacetime, because of the relativity of simultaneity to the inertial frame chosen, there is no unique world-at-an-instant. Thus the classical view that there is a unique set of events existing now in a three dimensional space cannot be sustained. The two solutions most often advanced are that the four-dimensional structure of events and processes is alone real, and that becoming present is not an objective part of reality; and that present existence is not an absolute notion, but is (...) relative to inertial frame; the world-at-an-instant is a three dimensional, but relative, reality. According to a third view, advanced by Robb, Capek and Stein, what is present at a given spacetime point is, strictly speaking, constituted by that point alone. I argue here against the first of these views that the four-dimensional universe cannot be said to exist now, already, or indeed at any time at all; so that talk of its existence or reality as if that precludes the existence or reality of the present is a non sequitur. The second view assumes that in relativistic physics time lapse is measured by the time co-ordinate function; against this I maintain that it is in fact measured by the proper time, as I argue by reference to the Twin Paradox. The third view, although formally correct, is tarnished by its unrealistic assumption of point-events. This makes it susceptible to paradox, and also sets it at variance with our normal intuitions of the present. I argue that a defensible concept of the present is nonetheless obtainable when account is taken of the non-instantaneity of events, including that of conscious awareness, as that region of spacetime comprised between the forward lightcone of the beginning of a small interval of proper time t and the backward lightcone of the end of that interval. This gives a serviceable notion of what is present to a given event of short duration, as well as saving our intuition of the “reality” or robustness of present events. (shrink)

This set is a carefully balanced selection of writings representing some of the most important currents in the thought of city and regional planning during the period 1870-1940 when urban planning emerged as a serious disciplinary field. The set consists of eight key books from this period, handsomely illustrated and reproduced in their entirety, and a separate volume of fifteen seminal short selections - all by major figures of the time, such as Abercrombie, Geddes, and the Olmsteds. Soria y Mata's (...) writings on the linear city also appear in translation for the first time. In addition to seminal works on city planning, the set covers themes such as neighbourhood, Utopian and visionary planning; planning for parks; housing; transportation systems, and public health. A wide variety of cities feature including Paris, Vienna, Amsterdam, Berlin, London, Manchester, New York and San Francisco, showing a great diversity of cultural styles. Early Urban Planning 1870-1940 is of continued importance today, as it highlights ideals which remain strikingly relevant in development of the twentieth and twenty-first centuries. (shrink)

The aim of this paper is to explain the significance of Alfred A. Robb’s philosophy of time stemming from his interpretation of relativity theory; and at the same time, to investigate the reasons for the failure of his philosophical contemporaries to appreciate its significance, with special attention to its reception on Russell’s part. The study of Russell’s reaction to Robb exposes shortcomings in Russell’s own philosophy of time, which has been extremely influential through the years. It also highlights the philosophical (...) differences between Minkowski and Robb, the shared idealistic premises of Russell and McTaggart, and the confluences between the views of Russell, Eddington and McTaggart. The paper closes with an account of how Robb’s interpretation has been vindicated by its adoption in modern physics. (shrink)

In Century of Genius: European Thought 1600-1700, Richard T. Vann links selections from the writings of such thinkers as Galileo, Bacon, Hobbes, Pascal, and Newton with interpretative commentary to show how seventeenth-century discoveries in science and mathematics not only changed the way in which men viewed the sun and the fall of apples from a tree, but also influenced forever afterward men's view of themselves. In Vann's interpretation, the spirit of the age was one of confidence and quest, given (...) perhaps its most eloquent expression in Milton's serene assurance that "though all the winds of doctrine were let loose to play upon the earth, so Truth be in the field ... let her and falsehood grapple; who ever knew Truth put to the worse in a free and open encounter?".

It is well known that Leibniz advocated the actual infinite, but that he did not admit infinite collections or infinite numbers. But his assimilation of this account to the scholastic notion of the syncategorematic infinite has given rise to controversy. A common interpretation is that in mathematics Leibniz’s syncategorematic infinite is identical with the Aristotelian potential infinite, so that it applies only to ideal entities, and is therefore distinct from the actual infinite that applies to the actual world. Against this, (...) I argue in this paper that Leibniz’s actual infinite, understood syncategorematically, applies to any entities that are actually infinite in multitude, whether numbers, actual parts of matter, or monads. It signifies that there are more of them than can be assigned a number, but that there is no infinite number or collection of them, which notion involves a contradiction. Similarly, to say that a magnitude is actually infinitely small in the syncategorematic sense is to say that no matter how small a magnitude one takes, there is a smaller, but there are no actual infinitesimals. In geometry one may calculate with expressions apparently denoting such entities, on the understanding that they are fictions, standing for variable magnitudes that can be made arbitrarily small, so as to produce demonstrations that there is no error in the resulting expressions.

This paper examines the efficacy of a statelessness reduction plan implemented by the country of Chile. We evaluate the programmatic alignment of Chile’s statelessness reduction plan, #Chilereconoce, with policy enacted by the United Nations High Commissioner for Refugees in that office’s campaign to eradicate statelessness by the year 2024. In addition to evaluating the structure of Chile’s statelessness reduction plan, we explore the policy outcomes of this plan in achieving its desired goal of reducing statelessness in Chile. We use Chile (...) as a case study because it implemented the United Nations High Commissioner for Refugees’ 2014-2024 Action Plan and, therefore, can shed light on if such a plan can put a nation-state on the path to remedy the deleterious effects of statelessness. Our central argument is that Chile’s statelessness reduction plan can, in-fact, serve as a blueprint for governmental institutions to follow towards achieving the goal of reducing statelessness. The success of such a plan, however, is conditioned upon whether principle actors within governmental institutions confront, head on, structural challenges that otherwise tend to undermine the merging of a confluence of critical factors that must be aligned for success to occur. The Chilean project demonstrates that reducing statelessness requires community action, implementation of domestic legislative reform, and governmental accession to international treaties. (shrink)

In this age of interdisciplinary interaction, we probably owe one another disclosures of our qualifications for commenting on each other’s profession. And you might well wonder why a philosopher would be asked to address this distinguished society of professiona l geologists. So, let me give what information I can about my qualifications to talk this evening about, of all things, the ethics of water geology.

This is a reply to Samuel Levey's fine review of my Monads, Composition and Force (Oxford UP, 2018) in the same issue of the Leibniz Review. In it I take up various difficulties raised by Levey that may be thought to collapse Leibniz's position into idealism after all, and attempt to provide convincing responses to them.

At the turn of the century Bertrand Russell advocated an absolutist theory of space and time, and scornfully rejected Leibniz’s relational theory in his Critical Exposition of the Philosophy of Leibniz. But by the time of the second edition, he had proposed highly influential relational theories of space and time that had much in common with Leibniz’s own views. Ironically, he never acknowledges this. In trying to get to the bottom of this enigma, I looked further at contemporary texts by (...) Russell, and also those he might have relied on, especially that of Robert Latta. I found that, like Latta’s, Russell’s interpretation of Leibniz was heavily conditioned by his immersion in neo-Hegelian and neo-Kantian philosophy prior to 1898, and that the doctrine of internal relations he attributes to Leibniz was more nearly the view of Lotze.

This article responds to a common criticism of Aristotelian naturalism known as the Pollyanna Problem, the objection that Aristotelian naturalism, when combined with recent empirical research, generates morally unacceptable conclusions. In developing a reply to this objection, I draw upon the conception of human nature developed by the ancient Chinese philosopher Mencius, and build up an account of ethical naturalism that provides a satisfying response to the Pollyanna Problem while also preserving what is most attractive about Aristotelian naturalism.

This paper consists in a study of Leibniz’s argument for the infinite plurality of substances, versions of which recur throughout his mature corpus. It goes roughly as follows: since every body is actually divided into further bodies, it is therefore not a unity but an infinite aggregate; the reality of an aggregate, however, reduces to the reality of the unities it presupposes; the reality of body, therefore, entails an actual infinity of constituent unities everywhere in it. I argue that this (...) depends on a generalized notion of aggregation, according to which a thing may be an aggregate of its constituents if every one of its actual parts presupposes such constituents, but is not composed from them. One of the premises of this argument is the reality of bodies. If this premise is denied, Leibniz’s argument for the infinitude of substances, and even of their plurality, cannot go through.

Ariès's Centuries of Childhood initially was largely ignored by scholars and scholarly journals who could not locate the book within traditional disciplines. But the influence of the book grew steadily, and it has played a formative role in the history of the family and the histoire des mentalités. Ariès had three theses: that childhood was invented in the seventeenth century; that the invention of childhood arose from the dual impulses of parents to coddle their children and, along with schoolmasters, to (...) pay greater attention to forming the children's characters through education; and that the concept of childhood led to an intense and pri~,atized mode of parent-child relations. The first thesis is the most dubious, but in the light of new research none of them seems likely to endure. A new interpretative framework will be required. Nonetheless, Ariès's work will endure in the history of historiography because he established the history of childhood as a field. (shrink)

The rule that a patient should give a free, fully-informed consent to any therapeutic intervention is traditionally thought to express merely a right of the patient against the physician, and a duty of the physician towards the patient. On this view, the patient may waive that right with impugnity, a fact sometimes expressed in the notion of a right not to know. This paper argues that the rule also expresses a duty of the patient towards the physician and a right (...) of the physician against the patient. The argument turns, first, on the truism that a physician has no obligation to commit a battery, or unauthorized touching, and, second, on the thesis that a patient necessarily cannot consent to something that is unknown to him. The conclusion is drawn that a patient is not free to receive treatment voluntarily without knowledgeably authorizing it. CiteULike Connotea Del.icio.us What's this? (shrink)
