This book connects the philosophy of Henri Bergson to contemporary debates in metaphysics and analytic philosophy of religion. More specifically, the book demonstrates how Bergson’s philosophy of time can respond to the problem of foreknowledge and free will. The question of how humans can be free if God knows everything has been a perennial issue of debate in analytic philosophy of religion. The solution to this problem relies heavily on what one thinks about time. The problem of time is central (...) to Bergson’s philosophical system. In this book, the author offers a systematic application of Bergson’s thought to the freedom and foreknowledge problem. The first chapter presents a discussion of Bergson’s central concept of la durée (duration). The subsequent two chapters link la durée to the relation of time and space. Here the author provides a Bergsonian response to McTaggart’s argument for the unreality of time and develops a novel theory of time connected to Bergson’s analysis of temporal experience. The last three chapters explore the relation between free will, determinism, and divine foreknowledge. The author reconstructs Bergson’s theory of freedom and shows how it undermines the underlying dogmas of contemporary free-will theories. The author then argues that Bergson’s philosophy can be used to resolve the free will and foreknowledge problem in philosophy of religion. The monograph concludes by opening avenues for new research into Bergson and analytic philosophy of religion, such as the philosophy of religious language, the relation between God and modality, religious experience, and religious pluralism.

J. M. E. McTaggart’s (1866-1925) argument for the unreality of time, first published in 1908, set the decisive framework for discussions about time in 20th-century analytic philosophy. This chapter provides an outline of the argument and situates it within the wider context of McTaggart’s philosophical system. It then provides an overview of a critique of McTaggart’s philosophical views on time by Hilda Oakeley (1867-1950). Oakeley was McTaggart’s contemporary and her critiques—while firmly based within their shared commitment to idealism—prefigure many later (...) criticisms and problems faced by 20th-century philosophers of time.

Introduction to the first special issue of Bergsoniana, a new journal in Bergson studies.

This paper explores the influence of Henri Bergson’s (1859–1941) philosophy of time on three early twentieth-century British philosophers: Karin Costelloe-Stephen (1889–1953), Hilda Oakeley (1867–1950), and May Sinclair (1863–1946). I demonstrate that three central claims of Bergson’s account of temporal experience (novelty, memory, and indivisibility) were creatively incorporated into their accounts of time. All these philosophers place time at the centre of their philosophical systems, so this study of their views on time and temporality can deepen our understanding of their systems (...) more broadly. Further, this study helps us appreciate the reception of Bergson’s thought in British philosophy after it was ferociously attacked by Bertrand Russell in 1912, and can provide more detailed contours on the joint fortunes of temporal experience and Bergson's thought in the history of twentieth-century philosophy. I conclude by emphasizing reasons why contemporary philosophers should pay particular attention to the three figures’ treatment of Bergson. (shrink)

The aim of this paper is to demonstrate that adjusting Stump and Kretzmann’s “atemporal duration” with la durée, a key concept in the philosophy of Henri Bergson, can respond to the most significant objections aimed at Stump and Kretzmann’s re-interpretation of Boethian eternity. This paper deals with three of these objections: the incoherence of the notion of “atemporal duration,” the impossibility of this duration being time-like, and the problems involved in conceiving it as being related to temporal duration by a (...) relation of analogy. I conclude that “atemporal duration” — when combined with Bergson’s durée to become an “atemporal durée” — is a coherent understanding of divine eternity. (shrink)

This paper provides a Bergsonian response to J.M.E. McTaggart’s argument for the unreality of time. McTaggart’s argument has been used as the primary framework for analytic discussions about time for over a hundred years. McTaggart argued that all events in time can be categorised in two ways: either using the A-series (whereby all events are ‘past,’ ‘present,’ or ‘future’) or the B-series (whereby two events are linked by the relation of ‘earlier’ and ‘later’). He argued that the A-series is contradictory (...) and that the B-series does not capture the nature of time. So he famously concluded that time is unreal. I demonstrate that McTaggart’s argument does not pay sufficient attention to the time of consciousness captured by Bergson’s durée. I show that two distinct temporal realms can be extracted from Bergson’s philosophy: (i) la durée and (ii) a mathematical time-ordering generally classified by analytic philosophers as the B-series. The A-series is shown to be an attempt to ‘have it all’ – to retain the features that apply only to the mathematical ordering (e.g., divisibility into distinct segments), but that also somehow contain only those features that apply to subjective temporal experience (e.g., the ‘flow’ of time).

The aim of this article is to reassess the similarity between Kripke’s metaphysics and Aquinas’ thought on truth, a similarity affirmed in Schultz-Aldrich’s Heythrop Journal article from 2009 and denied by Klima and Kerr in their analysis of Kripkean and Thomist accounts of essence. My claim is that this similarity has been insufficiently understood and its misunderstanding has closed off ways by means of which Aquinas’ thought can provide Kripkean epistemology with a component that it lacks.

C. D. Broad developed three different accounts of time over the course of his career. Emily Thomas has recently argued that the shift from the first to the second of these was motivated by his engagement with the philosophy of Samuel Alexander. In this paper, I argue that the shift from the second to the third was instigated by Broad’s engagement with precognitive dreams and with the thought of John William Dunne. Furthermore, I argue that fully appreciating Broad’s interest in (...) psychic research in general, and precognitions in particular, is required for understanding the theory of time he defended in the second volume of Examination of McTaggart’s Philosophy. I also argue that interpreting the Examination in light of Broad’s engagement with Dunne can help remove the inconsistencies in Broad’s third account. (shrink)

This paper argues that idealism can offer a new solution to the problem of relating the “static” presence of things to eternity and the “dynamic” passage of reality in the temporal realm. I first offer a presentation of this problem using the dispute between Aquinas and Scotus, then describe “ontological idealism about time,” as a smaller–scale idealism, and show how it resolves the original problem. I conclude by demonstrating that this view is consonant with the recent emphasis on the ontological (...) dependence of things on God and that it offers a way of bringing together non–eternalist ontologies and the ontological conclusions posited by the special theory of relativity.

The thesis uses key insights from the philosophy of Henri Bergson (1859-1941) to propose a new model of God’s relation to time. Chapter 1 is an introduction to Bergson’s philosophy against the background of Russell’s “The Philosophy of Bergson.” It provides an exposition of two key themes from Bergson central to my argument: the relation between time and space (Chapters 2-4) and the relation between free will and determinism (Chapter 5). Chapter 2 has a twofold task. First, it provides a (...) Bergsonian response to McTaggart’s argument for the unreality of time. Second, it uses the underlying metaphysics of McTaggart’s argument to demonstrate that two distinct temporal realms can be extracted from Bergson’s philosophy: (i) la durée and (ii) a mathematical time-ordering generally classified by analytic philosophy as the B-series. Chapter 3 relates this double-tier framework to temporal ontologies in analytic philosophy. I argue that such a framework supports an “ontological idealism about time.” I argue for relativizing temporal existence to distinct points or sets of points of spacetime that leads to a radical mind-dependence of temporal extension of objects. Chapter 4 explores how the durée-based ontology argued for in Chapter 3 impacts the relation between God and time. I argue that analytic philosophy has failed to capture key ontological facets of the God-time relation and that a return to divine “causal knowledge” is required. I demonstrate that the existence of temporal objects comes from two sources: (i) their mind-dependent temporal aspect and (ii) timeless divinely-created esse. Chapter 5 applies this framework to the problem of divine foreknowledge and human free will. I demonstrate that although Bergson’s theory can defend the existence of human freedom, his thought needs to be supplanted with divine “causal knowledge” to guarantee divine omniscience. (shrink)

This paper argues that the possibility of revealing counterfactuals of creaturely freedom to agents in possible worlds forming part of God’s natural knowledge poses a new problem for Molinism. This problem best comes to light when considering the phenomenon of stubbornness, i.e., the conscious refusal of fulfilling the providential plan revealed to and intended for us by another agent. The reason why this problem has gone unnoticed is that the usual instances of prophecy dealt with by Molinists are highly specific (...) cases. These cases are special for three reasons: because the content of the revelations does not include the relevant counterfactuals of creaturely freedom, because the specific revelation plays no causal role in the immediate circumstances of the action that the agent is performing, and because the agent is not intent on consciously refusing the providential plan intended by the relevant counterfactual. I explore possible worlds where one or more of these three conditions do not obtain and demonstrate the consequences these possible worlds have for Molinists. (shrink)

In this paper, we argue that the French philosopher Henri Bergson was a hidden interlocutor in Susan Stebbing’s critique of Arthur Eddington in her Philosophy and the Physicists. First, we outline Stebbing’s critique of Eddington’s philosophical- physical writings with a particular emphasis on her case against Eddington’s account of the passage of time. Second, we provide evidence that Eddington’s philosophy is, at its core, Bergsonian and make the case that Eddington was directly influenced by Bergson’s philosophy of la durée. Third, (...) we lay out Stebbing’s critique of Bergsonism in her Pragmatism and French Voluntarism and identify important similarities with her critique of Eddington over twenty years later. In doing so, we show that it is Eddington’s Bergsonism that she is attacking. Finally, we situate Stebbing’s criticisms of both Eddington and Bergson within two wider conflicts that emerged in early twentieth century British philosophy: one between an objectively describable time of physics and subjective temporal experience, and the other between science and intuition.

This paper explores a variety of perfect being theism that combines Yujin Nagasawa’s maximal God thesis with the view that God is not atemporal. We argue that the original maximal God thesis still implicitly relies on a “static” view of divine perfections. Instead, following the recent re-evaluation of divine immutability by analytic philosophers, we propose that thinking of divine great-making properties as fluctuating but nevertheless remaining maximal either for every time t or across all times strengthens the original maximal God (...) thesis. Furthermore, we show that “temporalising” Nagasawa’s maximal God and adopting what we call the fluctuating maximal God thesis provides more effective ways of responding to objections to perfect being theism, in particular, the argument from evil and some conceptual problems pertaining to the Incarnation. Finally, we demonstrate that our proposal is compatible with Christian Scriptures and coheres with numerous biblical passages better than Nagasawa’s original proposal does. (shrink)

Machines will attain human levels of intelligence by the year 2040, predicts robotics expert Hans Moravec. And by 2050, they will have far surpassed us. In this mind-bending new book, Hans Moravec takes the reader on a roller coaster ride packed with such startling predictions. He tells us, for instance, that in the not-too-distant future, an army of robots will displace workers, causing massive, unprecedented unemployment. But then, says Moravec, a period of very comfortable existence will follow, (...) as humans benefit from a fully automated economy. And eventually, as machines evolve far beyond humanity, robots will supplant us. But if Moravec predicts the end of the domination by human beings, his is not a bleak vision. Far from railing against a future in which machines rule the world, Moravec embraces it, taking the startling view that intelligent robots will actually be our evolutionary heirs. "Intelligent machines, which will grow from us, learn our skills, and share our goals and values, can be viewed as children of our minds." And since they are our children, we will want them to outdistance us. In fact, in a bid for immortality, many of our descendants will choose to transform into "ex humans," as they upload themselves into advanced computers. We will become our children and live forever. In his provocative new book, the highly anticipated follow-up to his bestselling volume Mind Children, Moravec charts the trajectory of robotics in breathtaking detail. A must read for artificial intelligence, technology, and computer enthusiasts, Moravec's freewheeling but informed speculations present a future far different than we ever dared imagine. (shrink)

In Quaestiones 1.3 and 2.14, Alexander presents a distinctly realist or essentialist view of the objects of definition, distinguished, on the one hand, from two types of realism rejected by Aristotle, and, on the other, from two types of conceptualism that probably belong within the Peripatetic tradition. The difference between Alexander’s view and essentialist abstractivism lies in his understanding of definienda not as the common concepts of things existing in the particulars, but as the common things conceived of as existing (...) in the particulars. This paper offers a close reading of Quaest. 1.3, whose aim is to flesh out Alexander’s position vis-à-vis the objects of definition against the backdrop of the four rejected alternatives. The distinction between Alexander’s essentialism and the essentialist abstractivist notion of definienda is further explained in light of Quaest. 2.14. The amended Greek text of Quaest. 1.3 is appended with an English translation. (shrink)

Este breve ensayo complementa en aspectos esenciales la argumentación de mi libro Introducción a la filosofía de la vocación en la medida en que se analiza la experiencia de la vocación desde el punto de vista de la estética. Me centro en cinco preguntas con respecto a la obra de Felice Casorati titulada Vocation. Primero, partiendo del título de la obra en relación con la desnudez de la figura ilumino la diferencia entre una interpretación santa y profana. En el segundo (...) capítulo intento captar y describir el sujeto de la vocación, uno de las protagonistas de este drama. El tercer capítulo está dedicado a caracterizar el contexto de la vocación con atención especial a la esperanza. El siguiente punto trata del análisis de la experiencia temporal de la vocación. El quinto paso es un nuevo acercamiento a la pregunta más esencial: ¿quién es el que llama en la vocación? El último punto es una recogida de los resultados, es decir, aquellos aspectos esenciales que nos sirven como puntos orientativos para vivir y expresar mejor la vocación como pleno sentido de la existencia.

I investigate the complex relationship between politics and philosophy by focusing on the notion of testimony. I argue that there is a necessary and fruitful tension between sapiential and political life. Testimony is characterized here as a free value-response in an intersubjective relation that requires empathy on both sides of the communication. This act of affirming a truth or value goes beyond the limits of prudent self-realization and self-preservation: authentic testimony requires some kind of self-sacrifice. I contrast this general image (...) of testimony to Jan Patočka’s interpretation of «care for the soul». Patočka, by following the early Husserl’s renewal of philosophy, managed to establish and to preserve the harmony between theory and praxis even during persecution of the communist regime. His courageous acts come close to and illuminate the testimony of Edith Stein, who set the measure for philosophical authenticity and self-donation. The comparison of these two testimonies helps to elaborate the notion of exemplary sapiential life — a highly relevant notion for politics. (shrink)

Computers have far to go to match human strengths, and our estimates will depend on analogy and extrapolation. Fortunately, these are grounded in the first bit of the journey, now behind us. Thirty years of computer vision reveals that 1 MIPS can extract simple features from real-time imagery--tracking a white line or a white spot on a mottled background. 10 MIPS can follow complex gray-scale patches--as smart bombs, cruise missiles and early self-driving vans attest. 100 MIPS can follow moderately unpredictable (...) features like roads--as recent long NAVLAB trips demonstrate. 1,000 MIPS will be adequate for coarse-grained three-dimensional spatial awareness--illustrated by several mid-resolution stereoscopic vision programs, including my own. 10,000 MIPS can find three-dimensional objects in clutter--suggested by several "bin-picking" and high-resolution stereo-vision demonstrations, which accomplish the task in an hour or so at 10 MIPS. The data fades there--research careers are too short, and computer memories too small, for significantly more elaborate experiments. (shrink)

The article is an analysis of a chapter dealing with the Aristotelian categories in the so-called eighth book of Stromata by Clement of Alexandria, a collection of notes from a philosophical source (or sources) concerned with the theory of demonstration and related issues. Though seldom mentioned in contemporary scholarship, this short chapter is a valuable testimony of the reception of the Categories in the philosophy of the Imperial period and before the time of Alexander of Aphrodisias. After a brief survey (...) of its contents, the article investigates parallels in philosophical literature and explores the function of the chapter within the larger context of Stromata VIII. In the final section the question of Clement's source is addressed. Drawing on earlier research concerning other parts of the eighth book, the article argues that in this case, too, Galen's lost writing on demonstration is a likely candidate. (shrink)

Serious attempts to build thinking machines began after the second world war. One line of research, called Cybernetics, used electronic circuitry imitating nervous systems to make machines that learned to recognize simple patterns, and turtle-like robots that found their way to recharging plugs. A different approach, named Artificial Intelligence, harnessed the arithmetic power of post-war computers to abstract reasoning, and by the 1960s made computers prove theorems in logic and geometry, solve calculus problems and play good games of checkers. At (...) the end of the 1960s, research groups at MIT and Stanford attached television cameras and robot arms to their computers, so "thinking" programs could begin to collect information directly from the real world.

Following the cart meeting of June 13, in which it was agreed that McCarthy would buy the cart project a TV transmitter if I could demonstrate my ability to do work on vision by writing a program which extracted three dimensional information from a motion stereo sequence of pictures, I began work on this task. So that there would be no doubt as to who had done the work, and because I operate most comfortably and effectively in a programming environment (...) made to my own tastes, the first order of business was the writing of a set of graphics and picture utility routines. The resulting package provides more flexibility than Quam's III buffer based routines, and is more cohesive than Baumgart's set, which is spread out among several programs. Currently the package accesses Data Disc displays only, in future it will be extended to provide output to the XGP and maybe the III's. As an example of increased capabilities, it allows display of filled in polygons, and permits displays to be shrunk or expanded arbitrarily merely by changing the declared dimensions of the screen or the requested sizes of the individual parts. Also, selected areas of the display may be erased or complemented, as well as added to. The programs described below use no previously existing software other than the FAIL and SAIL compilers and the operating system. (shrink)

Chapter 7 of Robot was my first presentation of a surprising chain of reasoning. I wanted to rewrite it, but didn't have the energy in time for publication.

This is a proposal for the re-activation of the essentially stillborn automatic car project for which the cart was originally obtained, and presents a process through which this activation could be accomplished painlessly.

Since I seem to be the only one, apart from John McCarthy, with an active interest in this aspect of things, (...) the following is written entirely from my point of view. (shrink)

Exploration and colonization of the universe await, but Earth‐adapted biological humans are ill equipped to respond to the challenge. Machines have gone farther and seen more, limited though they presently are by insect‐like behavioral inflexibility.

The unprecedented opportunities for experiments in complexity presented by the first modern computers in the late 1940's raised hopes in early computer scientists (eg. John von Neumann and Alan Turing) that the ability to think, our greatest asset in our dealings with the world, might soon be understood well enough to be duplicated. Success in such an endeavor would extend mankind's mind in the same way that the development of energy machinery extended his muscles.

In recent years the mushrooming power, functionality and ubiquity of computers and the Internet have outstripped early forecasts about technology's rate of advancement and usefulness in everyday life. Alert pundits now foresee a world saturated with powerful computer chips, which will increasingly insinuate themselves into our gadgets, dwellings, apparel and even our bodies.

The last few years have been good for time machines. Kip Thorne's renowned general relativity group at Caltech invented a new quantum gravitational approach to building a time gate, and, in an international collaboration, gave a plausible rebuttal of "grandfather paradox" arguments against time travel. Another respected group suggested time machines that exploit quantum mechanical time uncertainty. The technical requirements for these suggestions exceed our present capabilities, but each new approach seems less onerous than the last. There is hope yet (...) that time travel will eventually become possible, even cheap. (shrink)

Folk psychology is under threat - that is to say - our everyday conception that human beings are agents who experience the world in terms of sights, sounds, tastes, smells and feelings and who deliberate, make plans, and generally execute actions on the basis of their beliefs, needs and wants - is under threat.

It is often thought that either folk psychology or modern cognitive science must go. It is in these terms that the battle lines of today's philosophy of mind are drawn. (shrink)

This paper describes some components of a working system which drives a vehicle through cluttered real world environments under computer control, guided by images perceived through an onboard television camera. The emphasis is on reliable and fast low level visual techniques which determine the existence and location of objects in the world, but do not identify them. They include an interest operator for choosing distinctive regions in images, a correlator for finding matching regions in similar images, a geometric camera solver (...) which determines camera displacement and distance to objects from motion stereo information and an automatic distortion corrector which compensates for camera imperfections.

Exploration and colonization of the universe awaits, but earth-adapted biological humans are ill-equipped to respond to the challenge. Machines have gone farther and seen more, limited though they presently are by insect-like behavioral inflexibility. As they become smarter over the coming decades, space will be theirs. Organizations of robots of ever increasing intelligence and sensory and motor ability will expand and transform what they occupy, working with matter, space and time. As they grow, a smaller and smaller fraction of their (...) territory will be undeveloped frontier. Competitive success will depend more and more on using already available matter and space in ever more refined and useful forms. The process, analogous to the miniaturization that makes today's computers a trillion times more powerful than the mechanical calculators of the past, will gradually transform all activity from grossly physical homesteading of raw nature, to minimum-energy quantum transactions of computation. The final frontier will be urbanized, ultimately into an arena where every bit of activity is a meaningful computation: the inhabited portion of the universe will transformed into a cyberspace.

Computers have invaded everyday life, and networked machines are worming their way into our gadgets, dwellings, clothes, even bodies. But if pervasive computing soon handles most of our information needs, it will still not clean the floors, take out the garbage, assemble kit furniture or do any of a thousand other other essential physical tasks. The old dream of mechanical servants will remain mostly unmet.
