The feasibility of reversing human aging within a matter of decades has traditionally been dismissed by all professional biogerontologists, on the grounds that not only is aging still poorly understood, but also many of those aspects that we do understand are not reversible by any current or foreseeable therapeutic regimen. This broad consensus has recently been challenged by the publication, by five respected experimentalists in diverse subfields of biogerontology together with three of the present authors, of an article (Ann NY (...) Acad Sci 959, 452–462) whose conclusion was that all the key components of mammalian aging are indeed amenable to substantial reversal (not merely retardation) in mice, with technology that has a reasonable prospect of being developed within about a decade. Translation of that panel of interventions to humans who are already alive, within a few decades thereafter, was deemed potentially feasible (though it was not claimed to be likely). If the prospect of controlling human aging within the foreseeable future cannot be categorically rejected, then it becomes a matter of personal significance to most people presently alive. Consequently, we suggest that serious public debate on this subject is now warranted, and we survey here several of the biological, social and political issues relating to it.

Recording and manipulating neuronal ensemble activity is a key requirement in advanced neuromodulatory and behavior studies. Devices capable of both recording and manipulating neuronal activity brain-computer interfaces should ideally operate un-tethered and allow chronic longitudinal manipulations in the freely moving animal. In this study, we designed a new intracortical BCI feasible of telemetric recording and stimulating local gray and white matter of visual neural circuit after irradiation exposure. To increase the translational reliance, we put forward a Göttingen minipig model. The (...) animal was stereotactically irradiated at the level of the visual cortex upon defining the target by a fused cerebral MRI and CT scan. A fully implantable neural telemetry system consisting of a 64 channel intracortical multielectrode array, a telemetry capsule, and an inductive rechargeable battery was then implanted into the visual cortex to record and manipulate local field potentials, and multi-unit activity. We achieved a 3-month stability of the functionality of the un-tethered BCI in terms of telemetric radio-communication, inductive battery charging, and device biocompatibility for 3 months. Finally, we could reliably record the local signature of sub- and suprathreshold neuronal activity in the visual cortex with high bandwidth without complications. The ability to wireless induction charging combined with the entirely implantable design, the rather high recording bandwidth, and the ability to record and stimulate simultaneously put forward a wireless BCI capable of long-term un-tethered real-time communication for causal preclinical circuit-based closed-loop interventions.

The paper shows that in the Art of Thinking (The Port Royal Logic) Arnauld and Nicole introduce a new way to state the truth-conditions for categorical propositions. The definition uses two new ideas: the notion of distributive or, as they call it, universal term, which they abstract from distributive supposition in medieval logic, and their own version of what is now called a conservative quantifier in general quantification theory. Contrary to the interpretation of Jean-Claude Parienté and others, the truth-conditions do (...) not require the introduction of a new concept of ‘indefinite’ term restriction because the notion of conservative quantifier is formulated in terms of the standard notion of term intersection. The discussion shows the following. Distributive supposition could not be used in an analysis of truth because it is explained in terms of entailment, and entailment in terms of truth. By abstracting from semantic identities that underlie distribution, the new concept of distributive term is definitionally prior to truth and can, therefore, be used in a non-circular way to state truth-conditions. Using only standard restriction, the Logic’s truth-conditions for the categorical propositions are stated solely in terms of (1) universal (distributive) term, (2) conservative quantifier, and (3) affirmative and negative proposition. It is explained why the Cartesian notion of extension as a set of ideas is in this context equivalent to medieval and modern notions of extension. (shrink)

The mediaeval logic of Aristotelian privation, represented by Ockham's expositionof All A is non-P as All S is of a type T that is naturally P and no S is P, iscritically evaluated as an account of privative negation. It is argued that there aretwo senses of privative negation: (1) an intensifier (as in subhuman), the dualof Neoplatonic hypernegation (superhuman), which is studied in linguistics asan operator on scalar adjectives, and (2) a (often lexicalized) Boolean complementrelative to the extension of (...) a privative negation in sense (1) (e.g., Brute). Thissecond sense, which is the privative negation discussed in modern linguistics, isshown to be Aristotle's. It is argued that Ockham's exposition fails to capture muchof the logic of Aristotelian privation due to limitations in the expressive power of thesyllogistic. (shrink)

An interpretation in modal and tense logic is proposed for Boethius's reconciliation of God's foreknowledge with human freedom from The consolation of philosophy, Book V. The interpretation incorporates a suggestion by Paul Spade that God's special status in time be explained as a restriction of God's knowledge to eternal sentences. The argument proves valid, and the seeming restriction on omnipotence is mitigated by the very strong expressive power of eternal sentences.

Isaiah Berlin was the greatest intellectual historian of the twentieth century. But his work also made an original and important contribution to moral and political philosophy and to liberal theory. In 1921, at the age of eleven, Isaiah Berlin arrived in England from Riga, Latvia. By the time he was thirty he was at the heart of British intellectual life. He has remained its commanding presence ever since, and few would dispute that he was one of Britain's greatest thinkers. His (...) reputation extends worldwide--as a great conversationalist, intellectual historian, and man of letters. He has been called the century's most inspired reader. Yet Berlin's contributions to thought--in particular to moral and political philosophy, and to liberal theory--are little understood, and surprisingly neglected by the academic world. In this book, they are shown to be animated by a single, powerful, subversive idea: value-pluralism which affirms the reality of a deep conflict between ultimate human values that reason cannot resolve. Though bracingly clear-headed, humane and realist, Berlin's value-pluralism runs against the dominant Western traditions, secular and religious, which avow an ultimate harmony of values. It supports a highly distinctive restatement of liberalism in Berlin's work--an agnostic liberalism, which is founded not on rational choice but on the radical choices we make when faced with intractable dilemmas. It is this new statement of liberalism, the central subject of John Gray's lively and lucid book, which gives the liberal intellectual tradition a new lease on life, a new source of life, and which comprises Berlin's central and enduring legacy. In a new introduction, Gray argues that, in a world in which human freedom has spread more slowly than democracy, Berlin's account of liberty and basic decency is more instructive and useful than ever.

A great philosopher will change the way you think about your life. For most of human history, religion provided a clear explanation of life and death. But in the late 19th and early 20th centuries new ideas -- from psychiatry to evolution to Communist -- seemed to suggest that our fate was now in our own hands. We would ourselves become God. This is the theme of a remarkable new book by one of the world's greatest lving philosophers. It is (...) a brilliant and frightening look at the problems and opportunities of a world coming to grips with humankind's now solitary, unaided place in the universe. Gray takes two major examples: the belief that the science-backed Communism of the new USSR could reshape the planet, and the belief among a group of Edwardian intellectuals -- popularized through mediums and automatic writing -- that there was a non-religious form of life after death. Gray presents an extraordinary cast of philosophers, journalists, politicians, charlatans and mass murderers, all of whom felt driven by a specifically scientific and modern world view. He raises a host of fascinating questions about what it means to be human. The implications of Gray's book will haunt its readers for the rest of their lives. (shrink)

_Liberalisms_, a work first published in 1989, provides a coherent and comprehensive analytical guide to liberal thinking over the past century and considers the dominance of liberal thought in Anglo-American political philosophy over the past 20 years. John Gray assesses the work of all the major liberal political philosophers including J. S. Mill, Herbert Spencer, Karl Popper, F. A Hayek, John Rawls and Robert Nozick, and explores their mutual connections and differences.

Philosophy is one of the most intimidating and difficult of disciplines, as any of its students can attest. This book is an important entry in a distinctive new series from Routledge: The Great Philosophers . Breaking down obstacles to understanding the ideas of history's greatest thinkers, these brief, accessible, and affordable volumes offer essential introductions to the great philosophers of the Western tradition from Plato to Wittgenstein. In just 64 pages, each author, a specialist on his subject, places the philosopher (...) and his ideas into historical perspective. Each volume explains, in simple terms, the basic concepts, enriching the narrative through the effective use of biographical detail. And instead of attempting to explain the philosopher's entire intellectual history, which can be daunting, this series takes one central theme in each philosopher's work, using it to unfold the philosopher's thoughts.

In a series of important papers, G.A. Cohen has developed a forceful argument for the claim that workers are rendered unfree by capitalist institutions. His argument poses a powerful challenge to those who think that capitalist institutions best promote freedom. Yet, formidable as it is, Cohen's argument can be shown to be flawed at several crucial points. It is not one argument, but three at least, and one of the goals of my criticism of Cohen on this question is to (...) distinguish and assess the various separate lines of reasoning that together make up his case for the unfreedom under capitalism of workers as a class. Cohen argues of workers that they are rendered unfree by the institution of private property on which the capitalist system depends, that they suffer a form of collective unfreedom under capitalism, and that they are forced to sell their labor power under capitalism.

ABSTRACT The recent revival of interest in theory leads the writers to examine a particular moment when a curriculum and the institution in which it occurred was explained and justified. Max Horkheimer's inaugural address to the Institute for Social Research in 1931 is summarised. The points made by the new Director of the Institute are examined in relation not only to his proposal for an inter‐disciplinary curriculum, but also to the nature of the institution and to the general justification of (...) higher education. The article concludes with a number of comments on the relevance of these proposals to some modern higher education issues. (shrink)

Why is the human imagination to blame for the worst crimes of the twentieth century? Why is progress a pernicious myth? Why is contemporary atheism just a hangover from Christian faith? John Gray, author of Straw Dogsand Black Mass, is one of the most original and iconoclastic thinkers of our time. In this pugnacious and brilliantly readable collection of essays from across his career, he smashes through humanity's most cherished beliefs to overturn our view of the world, and our (...) place in it. 'If humans are different from other animals it is chiefly in being governed by myths, which are not creations of the will but creatures of the imagination.' 'No traditional myth is as untruthful as the modern myth of progress. All prevailing philosophies embody the fiction that human life can be altered at will. Better aim for the impossible, they say, than submit to fate. Invariably, the result is a cult of human self-assertion that soon ends in farce.'. (shrink)

Does Anne Conway (1631–79) hold that the created world consists of a single underlying substance? Some have argued that she does; others have argued that she is a priority monist and so holds that there are many created substances, but the whole created world is ontologically prior to each particular creature. Against both of these proposals, this article makes the case for a substance pluralist interpretation of Conway: individual creatures are distinct substances, and the whole created world is not ontologically (...) prior to the individual creatures that compose it. The basic argument for such a view draws on Conway's claims about the freedom and moral responsibility of individual creatures. The pluralist reading is straightforwardly compatible with these claims, while the monistic readings are not. (shrink)

The British bestseller Straw Dogs is an exciting, radical work of philosophy, which sets out to challenge our most cherished assumptions about what it means to be human. From Plato to Christianity, from the Enlightenment to Nietzsche and Marx, the Western tradition has been based on arrogant and erroneous beliefs about human beings and their place in the world. Philosophies such as liberalism and Marxism think of humankind as a species whose destiny is to transcend natural limits and conquer the (...) Earth. John Gray argues that this belief in human difference is a dangerous illusion and explores how the world and human life look once humanism has been finally abandoned. The result is an exhilarating, sometimes disturbing book that leads the reader to question our deepest-held beliefs. Will Self, in the New Statesman , called Straw Dogs his book of the year: “I read it once, I read it twice and took notes . . . I thought it that good.” “Nothing will get you thinking as much as this brilliant book” ( Sunday Telegraph ). (shrink)

Turning his back on neoliberalism, voicing 'the end of history' and the unstoppable spread of liberal values across the globe, Gray's was a lone voice of scepticism. The thinking he criticised would lead to the invasion of Iraq. Today, its folly might seem obvious, but Gray has been trying to warn us for years.

In this 2nd edition, John Gray adds an extensive postscript which defends the interpretation of Mill set out in the first edition, but develops radical criticisms of the substance of Millian and other liberalism.

For more than three decades judgements of schools' quality have been dominated by the frameworks, developed by members of Her Majesty's Inspectorate (HMI). This article reviews the approaches employed in the national survey conducted for the Plowden Committee, subsequent surveys undertaken by HMI during the seventies and eighties and the changes brought about by the advent of the Office for Standards in Education (OFSTED) in the early nineties. The frameworks employed appear to have changed from one decade to the next, (...) sometimes subtly, at other times more radically. Overall, such changes have been sufficiently major for it to be difficult, if not impossible, to make anything other than the broadest statements about changes in the state and quality of the nation's schooling over time.

A study of the political philosophy of the Russian born thinker explains how Isaiah Berlin came to reject ideological frameworks in favor of a pluralism that acknowledges the inevitable diversity of human values.

For virtually all the major schools of Western opinion, the collapse of the Communist regimes in Eastern Europe and in the Soviet Union, between 1989 and 1991, represents a triumph of Western values, ideas, and institutions. If, for triumphal conservatives, the events of late 1989 encompassed an endorsement of “democratic capitalism” that augured “the end of history,” for liberal and social democrats they could be understood as the repudiation by the peoples of the former Soviet bloc of Marxism-Leninism in all (...) its varieties, and the reemergence of a humanist socialism that was free of Bolshevik deformation. The structure of political and economic institutions appropriate to the transition from post-Communism in the Soviet bloc to genuine civil society was, accordingly, modeled on Western exemplars—the example of Anglo-American democratic capitalism, of Swedish social democracy, or of the German social market economy— or on various modish Western academic conceptions, long abandoned in the Soviet and post-Soviet worlds, such as market socialism. No prominent school of thought in the West doubted that the dissolution of Communist power was part of a process of Westernization in which contemporary Western ideas and institutions could and would successfully be exported to the former Communist societies. None questioned the idea that, somewhere in the repertoire of Western theory and practice, there was a model for conducting the transition from the bankrupt institutions of socialist central planning, incorporated into the structure of a totalitarian state, to market institutions and a liberal democratic state. Least of all did anyone question the desirability, or the possibility, of reconstituting economic and political institutions on Western models, in most parts of the former Soviet bloc. (shrink)

Value-pluralism is commonly held to support liberal political morality. This is argued by John Rawls and his school and, more instructively, by Isaiah Berlin and Joseph Raz. Against this common view it is argued that a strong version of value-pluralism and liberalism are incompatible doctrines. Some varieties of ethical pluralism are distinguished, and the claim of value-incommensurability made by strong pluralism is elucidated. The argument that liberal political morality consists of principles of right that are unaffected by the truth (...) of strong pluralism is examined and rejected. Strong pluralism is understood as the view that some goods and bads are rationally incommensurable. It is argued that if strong value-pluralism is true, then liberal political morality cannot be defended. Neither negative liberty nor individual autonomy can have general priority if it is true that the central goods specified by liberal political morality are incommensurables. This difficulty is not avoided by liberal theories that do not demand the maximization of a single value such as liberty. If strong pluralism is true, then liberal institutions are not a standard of legitimacy by reference to which all regimes are to be assessed. They are merely one variety of modus vivendi . Liberal institutions have no universal legitimacy. Yet liberal cultures are partly constituted by a belief in the universal authority of the principles which inform their practices and institutions. This belief strong pluralism subverts. Value-pluralism and liberalism are rival doctrines. The political implication of strong pluralism is not liberalism but modus vivendi . Sometimes modus vivendi is best fostered by liberal institutions. Sometimes it is best fostered by non-liberal institutions. Where the latter is true, liberals and pluralists part company. (shrink)

In this book John Gray argues that we live in a time of endings for the ideologies that governed the modern period. The Enlightenment projects of universal emancipation animates all the political doctrines and movements that are central in contemporary western societies. Yet it does not reflect the reality of the plural world in which we live. The western cultural hegemony which the Enlightenment embodied is coming to a close. Western liberal societies are not precursors of a universal civilization, (...) but only one form of life among many in the late modern world. Our inherited stock of political ideas no longer tracks that world. The crisis of New Right thought is as profound as that of the Left. Green theorists and communitarian thinkers have not understood the deep diversity and intractable conflicts of contemporary societies. And postmodernists, whose thought is ruled by the dated utopias of the modern period, do not engage with the real conditions of the world's emerging postmodern societies. Late modern thought occurs in an interregnum between modern projects that are no longer credible and postmodern realities that many find intolerable. John Gray suggests that some Enlightenment hopes of progress must be extinguished if we are to learn to respect cultural diversity and accept ecological limits. Respect for the Earth and for other species and cultures means abandoning the utopian and arcadian projects that haunt modern thought. We should aim to moderate the impact of human activity on the Earth while alleviating the unavoidable evils of human life. Yet the hubris which treats the Earth as an instrument of human purposes, and which regards other cultures as approximations to a universal civilization, embodies ancient and powerful traditions. John Gray's aim is to question these traditions and thereby to prepare our thinking for a time of beginnings. (shrink)

Steven Nadler has argued that Spinoza can, should, and does allow for the possibility of suicide committed as a free and rational action. Given that the conatus is a striving for perfection, Nadler argues, there are cases in which reason guides a person to end her life based on the principle of preferring the lesser evil. If so, Spinoza’s disparaging statements about suicide are intended to apply only to some cases, whereas in others he would grant that suicide is dictated (...) by reason. Here, I object to Nadler’s interpretation by showing that it conflicts with Spinoza’s metaphysical psychology. Even given Nadler’s interpretation of the conatus doctrine, the possibility that reason could guide a person to commit suicide is incompatible with the conatus of the mind. Spinoza holds that the mind cannot contain an adequate idea ‘that excludes the existence of our body’. Yet, as I argue, in order for reason to guide a person voluntarily to end her life, she would need to have an adequate idea representing her death – an idea that excludes the existence of her body. For this reason, Spinoza's system rules out the possibility of rational suicide. (shrink)

I supply an argument for Evans's principle that whatever justifies me in believing that p also justifies me in believing that I believe that p. I show how this principle helps explain how I come to know my own beliefs in a way that normally makes me the best authority on them. Then I show how the principle helps to solve Moore's paradoxes.

G. E. Moore famously observed that to assert ‘I went to the pictures last Tuesday but I do not believe that I did’ would be ‘absurd’. Moore calls it a ‘paradox’ that this absurdity persists despite the fact that what I say about myself might be true. Krista Lawlor and John Perry have proposed an explanation of the absurdity that confines itself to semantic notions while eschewing pragmatic ones. We argue that this explanation faces four objections. We give a (...) better explanation of the absurdity both in assertion and in belief that avoids our four objections. (shrink)

It is raining but you don’t believe that it is raining. Imagine accepting this claim. Then you are committed to saying ‘It is raining but I don’t believe that it is raining’. This would be an ‘absurd’ thing to claim or assert, yet what you say might be true. It might be raining, while at the same time, you are completely ignorant of the state of the weather. But how can it be absurd of you to assert something about yourself (...) that might be true of you? This is Moore’s paradox as it occurs in speech. What is the source of the absurdity? And why does it strike us that a contradiction is somehow at work when there is no contradiction in the content of what is asserted? In Section 2, I describe Moore’s formulation of the paradox and evaluate his own solutions. In Section 3, I discuss Wittgenstein’s inf luence in solving the paradox. In Section 4, I discuss Shoemaker’s priority thesis that once the absurdity in belief has been explained, then this will translate into an explanation of the absurdity in assertion. In Section 5, I discuss work on omissive and commissive Moore-paradoxical assertions, i.e. those of the forms p & I don’t believe that p and p & I believe that not-p. In Section 6, I discuss work on assertions of the form p & I don’t know that p. (shrink)

In the Tractatus Theologico-Politicus (TTP), Spinoza argues that an individual’s natural right extends as far as their power. Subsequently, in the Tractatus Politicus (TP), he offers a revised argument for the same conclusion. Here I offer an account of the reasons for the revision. In both arguments, an individual’s natural right derives from God’s natural right. However, the TTP argument hinges on the claim that each individual is part of the whole of nature (totius naturae), and for this reason inherits (...) part of the natural right of that whole. Using several analogous cases from the Ethics, I show that this form of argument from division is not compatible with Spinoza’s considered metaphysical views. The revised argument, by contrast, avoids the pitfalls of his earlier efforts. It also better reveals the deep roots by which the monistic metaphysics of the Ethics feeds into Spinoza’s conception of natural right. (shrink)

Moore’s paradox is the fact that assertions or beliefs such asBangkok is the capital of Thailand but I do not believe that Bangkok is the capital of Thailand or Bangkok is the capital of Thailand but I believe that Bangkok is not the capital of Thailand are ‘absurd’ yet possibly true. The current orthodoxy is that an explanation of the absurdity should first start with belief, on the assumption that once the absurdity in belief has been explained then this will (...) translate into an explanation of the absurdity in assertion. This assumption gives explanatory priority to belief over assertion. I show that the translation involved is much trickier than might at first appear. It is simplistic to think that Moorean absurdity in assertion is always a subsidiary product of the absurdity in belief, even when the absurdity is conceived as irrationality. Instead we should aim for explanations of Moorean absurdity in assertion and in belief that are independent even if related, while bearing in mind that some forms of irrationality may be forms of absurdity even if not conversely.

It is raining but you don’t believe that it is raining. Imagine silently accepting this claim. Then you believe both that it is raining and that you don’t believe that it is raining. This would be an ‘absurd’ thing to believe,yet what you believe might be true. Itmight be raining, while at the same time, you are completely ignorant of the state of the weather. But how can it be absurd of you to believe something about yourself that might be (...) true of you? This is Moore’s paradox as it occurs in thought. Solving the paradox consists in explaining why such beliefs are absurd. I give a survey of some of the main explanations. I largely deal with explanations of the absurdity of ‘omissive’ beliefs with contents of the form p & I don’t believe that p and of ‘commissive beliefs’ with contents of the form p & I believe that not-p as well as beliefs with contents of the form p & I don’t know that p.

The account of natural kinds as stable property clusters is premised on the possibility of separating the epistemic value of natural kinds from their underlying metaphysics. On that account, the co-instantiation of any sub-cluster of the properties associated with a given natural kind raises the probability of the co-instantiation of the rest, and this clustering of property instantiation is invariant under all relevant counterfactual perturbations. We argue that it is not possible to evaluate the stability of a cluster of properties (...) without taking stock of the metaphysical picture used to account for that stability. Thus, even on the stable property cluster account, the epistemic value of natural kinds remains partly grounded in their metaphysical status. (shrink)

Collected here in a single volume for the first time, On Liberty, Utilitarianism, Considerations on Representative Government, and The Subjection of Women show Mill applying his liberal utilitarian philosophy to a range of issues that remain vital today - issues of the nature of ethics, the scope and limits of individual liberty, the merits of and costs of democratic government, and the place of women in society. In his Introduction John Gray describes these essays as applications of Mill's doctrine (...) of the Art of Life, as set out in A System of Logic. Using the resources of recent revisionist scholarship, he shows Mill's work to be far richer and subtler than traditional interpretations allow. (shrink)

Anne Conway rejects the view that creatures are essentially members of any natural kind more specific than the kind 'creature'. That is, she rejects essentialism about species membership. This chapter provides an analysis of one of Anne Conway's arguments against such essentialism, which (as I argue) is drawn from metaethical rather than metaphysical premises. In her view, if a creature's species or kind were inscribed in its essence, that essence would constitute a limit on the creature's potential to participate in (...) the divine good. It is this consideration that ultimately leads her to reject essentialism about species membership. The chapter concludes with an examination of some of the metaethical consequences of Conway's view as well as a lesson it can teach us about ideal adviser accounts of the good. (shrink)
