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 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. The project would be financed from the lab's operating grant, and would interact strongly with, while being independent of, any Mars rover research initiated by Lynn Quam. 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)

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.

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.

Though the revised edition of A Theory of Justice, published in 1999, is the definitive statement of Rawls's view, so much of the extensive literature on Rawls's theory refers to the first edition. This reissue makes the first edition once again available for scholars and serious students of Rawls's work.

John MacFarlane explores how we might make sense of the idea that truth is relative. He provides new, satisfying accounts of parts of our thought and talk that have resisted traditional methods of analysis, including what we mean when we talk about what is tasty, what we know, what will happen, what might be the case, and what we ought to do.

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)

What psychological and philosophical significance should we attach to recent efforts at computer simulations of human cognitive capacities? In answering this question, I find it useful to distinguish what I will call "strong" AI from "weak" or "cautious" AI. According to weak AI, the principal value of the computer in the study of the mind is that it gives us a very powerful tool. For example, it enables us to formulate and test hypotheses in a more rigorous and precise fashion. (...) But according to strong AI, the computer is not merely a tool in the study of the mind; rather, the appropriately programmed computer really is a mind, in the sense that computers given the right programs can be literally said to.

Normative requirements are often overlooked, but they are central features of the normative world. Rationality is often thought to consist in acting for reasons, but following normative requirements is also a major part of rationality. In particular, correct reasoning – both theoretical and practical – is governed by normative requirements rather than by reasons. This article explains the nature of normative requirements, and gives examples of their importance. It also describes mistakes that philosophers have made as a result of confusing (...) normative requirements with reasons. (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)

This book is the one to put into the hands of those who have been over-impressed by Austin 's critics....[Warnock's] brilliant editing puts everybody who is concerned with philosophical problems in his debt.

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)

This new edition of the classic Contemporary Theories of Knowledge has been significantly updated to include analyses of the recent literature in epistemology.

This study provides a comprehensive reinterpretation of the meaning of Locke's political thought. John Dunn restores Locke's ideas to their exact context, and so stresses the historical question of what Locke in the Two Treatises of Government was intending to claim. By adopting this approach, he reveals the predominantly theological character of all Locke's thinking about politics and provides a convincing analysis of the development of Locke's thought. In a polemical concluding section, John Dunn argues that liberal and (...) Marxist interpretations of Locke's politics have failed to grasp his meaning. Locke emerges as not merely a contributor to the development of English constitutional thought, or as a reflector of socio-economic change in seventeenth-century England, but as essentially a Calvinist natural theologian.

This is a selection of essays on moral responsibility that represent the major components of John Martin Fischer's overall approach to freedom of the will and moral responsibility. The collection exhibits the overall structure of Fischer's view and shows how the various elements fit together to form a comprehensive framework for analyzing free will and moral responsibility. The topics include deliberation and practical reasoning, freedom of the will, freedom of action, various notions of control, and moral accountability. The essays (...) seek to provide a foundation for our practices of holding each other (and ourselves) morally and legally accountable for our behavior. A crucial move is the distinction between two kinds of control. According to Fischer, "regulative control" involves freedom to choose and do otherwise ("alternative possibilities"), whereas "guidance control" does not. Fischer contends that guidance control is all the freedom we need to be morally responsible agents. Further, he contends that such control is fully compatible with causal determinism. Additionally, Fischer argues that we do not need genuine access to alternative possibilities in order for there to be a legitimate point to practical reasoning. Fischer's overall framework contains an argument for the contention that guidance control, and not regulative control, is associated with moral responsibility, a sketch of a comprehensive theory of moral responsibility (that ties together responsibility for actions, omissions, consequences, and character), and an account of the value of moral responsibility. On this account, the value of exhibiting freedom (of the relevant sort) and thus being morally responsible for one's behavior is a species of the value of artistic self-expression. (shrink)

John Hyman explores central problems in philosophy of action and the theory of knowledge, and connects these areas of enquiry in a new way. His approach to the dimensions of human action culminates in an original analysis of the relation between knowledge and rational behaviour, which provides the foundation for a new theory of knowledge itself.

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 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)

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.

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 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)

Reissued here in its corrected second edition of 1864, this essay by John Stuart Mill argues for a utilitarian theory of morality. Originally printed as a series of three articles in Fraser's Magazine in 1861, the work sought to refine the 'greatest happiness' principle that had been championed by Jeremy Bentham, defending it from common criticisms, and offering a justification of its validity. Following Bentham, Mill holds that actions can be judged as right or wrong depending on whether they (...) promote happiness or 'the reverse of happiness'. Although attracted by Bentham's consequentialist framework based on empirical evidence rather than intuition, Mill separates happiness into 'higher' and 'lower' pleasures, arguing for a weighted system of measurement when making and judging decisions. Dissected and debated since its first appearance, the essay is Mill's key discussion on the topic and remains a fundamental text in the study of ethics. (shrink)

I argue against the orthodox view of the relationship between propositional and doxastic justification. The view under criticism is: if p is propositionally justified for S in virtue of S's having reason R, and S believes p on the basis of R, then S's belief that p is doxastically justified. I then propose and evaluate alternative accounts of the relationship between propositional and doxastic justification, and conclude that we should explain propositional justification in terms of doxastic justification. If correct, this (...) proposal would constitute a significant advance in our understanding of the sources of epistemic justification. (shrink)

Creative Intelligence: Essays in the Pragmatic Attitude represents an attempt at intellectual cooperation. No effort has been made, however, to attain unanimity of belief nor to proffer a platform of "planks" on which there is agreement. The consensus represented lies primarily in outlook, in conviction of what is most likely to be fruitful in method of approach. As the title page suggests, the volume presents a unity in attitude rather than a uniformity in results. Consequently each writer is definitively responsible (...) only for his own essay. The reader will note that the Essays endeavor to embody the common attitude in application to specific fields of inquiry which have been historically associated with philosophy rather than as a thing by itself. Beginning with philosophy itself, subsequent contributions discuss its application to logic, to mathematics, to physical science, to psychology, to ethics, to economics, and then again to philosophy itself in conjunction with esthetics and religion. The reader will probably find that the significant points of agreement have to do with the ideas of the genuineness of the future, of intelligence as the organ for determining the quality of that future so far as it can come within human control, and of a courageously inventive individual as the bearer of a creatively employed mind.

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.

Intuition is sometimes derided as an abstruse or esoteric phenomenon akin to crystal-ball gazing. Such derision appears to be fuelled primarily by the suggestion, evidently endorsed by traditional rationalists such as Plato and Descartes, that intuition is a kind of direct, immediate apprehension akin to perception. This paper suggests that although the perceptual analogy has often been dismissed as encouraging a theoretically useless metaphor, a quasi-perceptualist view of intuition may enable rationalists to begin to meet the challenge of supplying a (...) theoretically satisfying treatment of their favoured epistemic source. It is argued, first, that intuitions and perceptual experiences are at a certain level of abstraction the same type of mental state, presentations, which are distinct from beliefs, hunches, inclinations, attractions, and seemings. The notion of a presentation is given a positive explication, which identifies its characteristic features, accounts for several of its substantive psychological roles, and systematically locates it in a threefold division among types of contentful states. Subsequently, it is argued that presentations, intuitive no less than sensory, are by their nature poised to play a distinctive epistemic role. Specifically, in the case of intuition, we encounter an intellectual state that is so structured as to provide justification without requiring justification in turn—something which may, thus, be thought of as ‘given’.

John Henry Newman was a theologian and vicar at the university church in Oxford who became a leading thinker in the Oxford Movement, which sought to return Anglicanism to its Catholic roots. Newman converted to Catholicism in 1845 and became a cardinal in 1879. He published widely during his lifetime; his work included novels, poetry and the famous hymn 'Lead, Kindly Light', but he is most esteemed for his sermons and works of religious thought. This volume, first published in (...) 1870, is an ambitious examination of the logical processes that underpin religious faith. Newman discusses how it is possible to believe what cannot be proven empirically, and postulates that the mind has the facility to bridge the logic gap to allow for humans to believe in things that they do not fully comprehend. A lucid and masterful work which remains relevant to contemporary discussions of faith. (shrink)
