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)

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.

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)

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.

In contrast with some recent theories of infinitesimals as non-Archimedean entities, Leibniz’s mature interpretation was fully in accord with the Archimedean Axiom: infinitesimals are fictions, whose treatment as entities incomparably smaller than finite quantities is justifiable wholly in terms of variable finite quantities that can be taken as small as desired, i.e. syncategorematically. In this paper I explain this syncategorematic interpretation, and how Leibniz used it to justify the calculus. I then compare it with the approach of Smooth Infinitesimal Analysis, (...) as propounded by John Bell. I find some salient differences, especially with regard to higher-order infinitesimals. I illustrate these differences by a consideration of how each approach might be applied to propositions of Newton’s Principia concerning the derivation of force laws for bodies orbiting in a circle and an ellipse. “If the Leibnizian calculus needs a rehabilitation because of too severe treatment by historians in the past half century, as Robinson suggests (1966, 250), I feel that the legitimate grounds for such a rehabilitation are to be found in the Leibnizian theory itself.”—(Bos 1974–1975, 82–83).

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 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.

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.

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)

This study develops a concept of “justificatory respect” and applies it to a recent theistic response to contemporary presentations ofatheism and agnosticism. The related concepts of reflexive justificatory respect (applying to one’s own positions) and of an associated epistemic virtue as necessary but not sufficient conditions for theists and unbelievers to engage one another in successful dialogical inquiry are also developed. Novak’s book signally fails to exercise both kinds of respect. His failures serve to partially delineate the condition for success (...) in the project he desiderates. They also highlight the special qualifications of agnostics for engaging in that project. (shrink)

Russell’s most important source for his book on Leibniz was C. I. Gerhardt’s seven-volume Die philosophischen Schriften von Gottfried Wilhelm Leibniz. Russell heavily annotated his copy of this important edition of Leibniz’s works. The present paper records all Russell’s marginalia, with the exception of passages marked merely by vertical lines in the margin, and provides explanatory commentary.

In this paper, I argue that the use of non-human animals in ritual sacrifices is not necessary for the Confucian tradition. I draw upon resources found within other religious traditions as well as Confucianism concerning carrying out even the most mundane, ordinary actions as expressions of reverence. I argue that this practice of manifesting deep reverence toward God through simple actions, which I call everyday reverence, reveals a way for Confucians to maintain the deep reverence that is essential for Confucianism, (...) while abandoning the use of non-human animal sacrifice.

In this interview, C. P. Goodman invites British Polanyi scholar Richard T. Allen to reflect on his interest in Polanyi’s philosophical ideas and share what he believes is valuable in his thought.

In preparation for his lectures on Leibniz delivered in Cambridge in Lent Term 1899, Russell started in the summer of 1898 to keep notes on writings by and about Leibniz in a large notebook of the type he commonly used for notetaking at this time. This article prints, with annotation, all the material on Leibniz in that notebook.

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)

This book gathers together for the first time an important body of texts written between 1672 and 1686 by the great German philosopher and polymath Gottfried Leibniz. These writings, most of them previously untranslated, represent Leibniz's sustained attempt on a problem whose solution was crucial to the development of his thought, that of the composition of the continuum. The volume begins with excerpts from Leibniz's Paris writings, in which he tackles such problems as whether the infinite division of matter entails (...) perfect points, whether matter and space can be regarded as true wholes, whether motion is truly continuous, and the nature of body and substance. Comprising the second section is Pacidius Philalethi, Leibniz's brilliant dialogue of late 1676 on the problem of the continuity of motion. In the selections of the final section, from his Hanover writings of 1677-1686, Leibniz abandons his earlier transcreationism and atomism in favor of the theory of corporeal substance, where the reality of body and motion is founded in substantial form or force.Leibniz's texts (one in French, the rest in Latin) are presented with facing-page English translations, together with an introduction, notes, appendixes containing related excerpts from earlier works by Leibniz and his predecessors, and a valuable glossary detailing important terms and their translations.

Only by distinguishing corporate, moral, social and legal responsibility can GM know how to weigh and respond to its various responsibilities. Corporate responsibility stems from the ends for which the corporation is formed. In addition the corporation is responsible for meeting the moral demands that come from the moral law. The corporation is responsible for meeting legitimate social demands proposed by society. If society uses the law to express its demands, the demands yield legal responsibilities. Those demands that are social (...) but neither moral nor legal may not be legitimate demands that GM must respond to at all. (shrink)

Pippin offers his reconstruction of Hegel's account of practical reason as a point of departure for contemporary social theory, yet he does not address the implications for us of Hegel's claim that social reflection can achieve its knowledge only on the basis of a world that has already become rational. After arguing that the unreasonableness of our world can be seen from the suffering it generates, I argue that an account of violence may be a way to retrieve the promise (...) of Hegelian insights so long as it draws in turn on existing challenges to violence and the suffering it causes. The argument discusses four kinds of violence (direct, formative, structural, and symbolic) and confronts these with a neo-Hegelian conception of social learning. (shrink)

This work is a publication of a manuscript left unfinished at his death by the author. From the time of their conversations in 1936, William Henry Werkmeister has studied the phenomenon of Martin Heidegger's thought and the critical literature commenting on it. During a period spanning 36 years, Werkmeister wrote some nine articles and reviews about his findings. He turned to other interests, but the Heidegger phenomenon continued to reside at the back of his mind. At age ninety, Werkmeister set (...) out once again to write a work that would unify Heidegger's thought, clarify a number of its essential features, place Heidegger's chief works in an order that corresponds to the time line of his thought, critically appraise the development of his thought against the work of other German philosophers, and assess the question of Heidegger's alleged Nazi sympathies.

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)
