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.

It is commonly held that there is no place for the 'now’ in physics, and also that the passing of time is something subjective, having to do with the way reality is experienced but not with the way reality is. Indeed, the majority of modern theoretical physicists and philosophers of physics contend that the passing of time is incompatible with modern physical theory, and excluded in a fundamental description of physical reality. This book provides a forceful rebuttal of such claims. (...) In successive chapters the author explains the historical precedents of the modern opposition to time flow, giving careful expositions of matters relevant to becoming in classical physics, the special and general theories of relativity, and quantum theory, without presupposing prior expertise in these subjects. Analysing the arguments of thinkers ranging from Aristotle, Russell, and Bergson to the proponents of quantum gravity, he contends that the passage of time, understood as a local becoming of events out of those in their past at varying rates, is not only compatible with the theories of modern physics, but implicit in them.

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.

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)

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. (shrink)

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).

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.

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 try to sort out a tangle of issues regarding time, inertia, proper time and the so-called “clock hypothesis” raised by Harvey Brown's discussion of them in his recent book, Physical Relativity. I attempt to clarify the connection between time and inertia, as well as the deficiencies in Newton's “derivation” of Corollary 5, by giving a group theoretic treatment original with J.-P. Provost. This shows how both the Galilei and Lorentz transformations may be derived from the relativity (...) principle on the basis of certain elementary assumptions regarding time. I then reflect on the implications of this derivation for understanding proper time and the clock hypothesis. (shrink)

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.

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)

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 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.

We start by surveying the different issues that fall under the umbrella of ‘multiculturalism’. We then sketch the trajectory of British multiculturalism since 1945, and examine its broader legal and philosophical contexts. This narrative highlights the empirical and theoretical connections between multiculturalism and decolonisation, and that the conceptualisation of multiculturalism in political theory is more wide-ranging than in law or policy. This helps foreground neglected aspects of British multiculturalism in policy and law, and suggests we should widen the philosophical scope (...) of multiculturalism even further. We then summarise the papers and draw out the connections between them. We argue that a deeper understanding of contemporary British multiculturalism inexorably leads us back to fundamental philosophical and practical questions regarding the structure and purpose of the British polity, and conclude that this indicates the need for greater polycentricity in governance.

William Hunter's anatomical inquiry employed all of his senses, but how did his personal experiences with the cadaver become generalized scientific knowledge teachable to students and understandable by fellow practitioners? Moving beyond a historiographical focus on Hunter's images and extending Lorraine Daston's (2008) concept of an ‘ontology of scientific observation’ to include non-visual senses, I argue that Hunter's work aimed to create a stabilized object of the cadaver that he and his students could perceive in common. Crucial to this stabilization (...) was the sense of touch and its interaction with other senses, creating intersensory knowledge of the cadaver. Through a close reading of his neglected posthumous publication An Anatomical Description of the Human Gravid Uterus (1794), I demonstrate that Hunter wrote extensively about touch and other sensory experiences, using comparative metaphors and other linguistic strategies to engender clear ideas of the cadaver in the mind of the reader. That these ideas could be consistent between practitioners was guaranteed by God, but required practitioners to appropriately reflect on their sensory experiences with cadavers. Hunter's experimental practice encompassed both simple and complex methods, all aimed at increasing the range of sensorial experiences he had with the gravid uterus. His preservations of these experiences in text, image and preparation could then be used to support further anatomical investigations. (shrink)

In line with the British Psychological Society's recent recommendations for teaching the history of psychology, this comprehensive undergraduate textbook emphasizes the philosophical, cultural and social elements that influenced psychology's development. The authors demonstrate that psychology is both a human (e.g. psychoanalytic or phenomenological) and natural (e.g. cognitive) science, exploring broad social-historical and philosophical themes such as the role of diverse cultures and women in psychology and the complex relationship between objectivity and subjectivity in the development of psychological knowledge. The result (...) is a fresh and balanced perspective on what has traditionally been viewed as the collected achievements of a few 'great men'. With a variety of learning features, including case studies, study questions, thought experiments and a glossary, this new textbook encourages students to critically engage with chapter material and analyze themes and topics within a social, historical and philosophical framework.

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.
