Automated reasoning about uncertain knowledge has many applications. One difficulty when developing such systems is the lack of a completely satisfactory integration of logic and probability. We address this problem directly. Expressive languages like higher-order logic are ideally suited for representing and reasoning about structured knowledge. Uncertain knowledge can be modeled by using graded probabilities rather than binary truth-values. The main technical problem studied in this paper is the following: Given a set of sentences, each having some probability of being (...) true, what probability should be ascribed to other (query) sentences? A natural wish-list, among others, is that the probability distribution (i) is consistent with the knowledge base, (ii) allows for a consistent inference procedure and in particular (iii) reduces to deductive logic in the limit of probabilities being 0 and 1, (iv) allows (Bayesian) inductive reasoning and (v) learning in the limit and in particular (vi) allows confirmation of universally quantified hypotheses/sentences. We translate this wish-list into technical requirements for a prior probability and show that probabilities satisfying all our criteria exist. We also give explicit constructions and several general characterizations of probabilities that satisfy some or all of the criteria and various (counter) examples. We also derive necessary and sufficient conditions for extending beliefs about finitely many sentences to suitable probabilities over all sentences, and in particular least dogmatic or least biased ones. We conclude with a brief outlook on how the developed theory might be used and approximated in autonomous reasoning agents. Our theory is a step towards a globally consistent and empirically satisfactory unification of probability and logic. (shrink)

The Repugnant Conclusion served an important purpose in catalyzing and inspiring the pioneering stage of population ethics research. We believe, however, that the Repugnant Conclusion now receives too much focus. Avoiding the Repugnant Conclusion should no longer be the central goal driving population ethics research, despite its importance to the fundamental accomplishments of the existing literature.

We are developing the Neurological Disease Ontology (ND) to provide a framework to enable representation of aspects of neurological diseases that are relevant to their treatment and study. ND is a representational tool that addresses the need for unambiguous annotation, storage, and retrieval of data associated with the treatment and study of neurological diseases. ND is being developed in compliance with the Open Biomedical Ontology Foundry principles and builds upon the paradigm established by the Ontology for General Medical Science (OGMS) (...) for the representation of entities in the domain of disease and medical practice. Initial applications of ND will include the annotation and analysis of large data sets and patient records for Alzheimer’s disease, multiple sclerosis, and stroke. (shrink)

The Meditations of Marcus Aurelius are treasured today--as they have been over the centuries--as an inexhaustible source of wisdom. And as one of the three most important expressions of Stoicism, this is an essential text for everyone interested in ancient religion and philosophy. Yet the clarity and ease of the work's style are deceptive. Pierre Hadot, eminent historian of ancient thought, uncovers new levels of meaning and expands our understanding of its underlying philosophy. Written by the Roman emperor for (...) his own private guidance and self-admonition, the Meditations set forth principles for living a good and just life. Hadot probes Marcus Aurelius's guidelines and convictions and discerns the hitherto unperceived conceptual system that grounds them. Abundantly quoting the Meditations to illustrate his analysis, the author allows Marcus Aurelius to speak directly to the reader. And Hadot unfolds for us the philosophical context of the Meditations, commenting on the philosophers Marcus Aurelius read and giving special attention to the teachings of Epictetus, whose disciple he was. The soul, the guiding principle within us, is in Marcus Aurelius's Stoic philosophy an inviolable stronghold of freedom, the "inner citadel." This spirited and engaging study of his thought offers a fresh picture of the fascinating philosopher-emperor, a fuller understanding of the tradition and doctrines of Stoicism, and rich insight on the culture of the Roman empire in the second century. Pierre Hadot has been working on Marcus Aurelius for more than twenty years; in this book he distills his analysis and conclusions with extraordinary lucidity for the general reader. (shrink)

Marcus Aurelius, philosopher-emperor, wrote the Meditations in periods of solitude during military campaigns. His ethical, religious, and existential reflections have endured as an expression of Stoicism, a text for students of that philosophy, and a guide to the moral life. Marcus Aurelius, Roman emperor and Stoic philosopher, born at Rome, received training under his guardian and uncle emperor Antoninus Pius, who adopted him. He was converted to Stoicism and henceforward studied and practised philosophy and law. A gentle man, (...) he lived in agreement and collaboration with Antoninus Pius. He married Pius's daughter and succeeded him as emperor in March 161, sharing some of the burdens with Lucius Verus. Marcus's reign soon saw fearful national disasters from flood, earthquakes, epidemics, threatened revolt, a Parthian war, and pressure of barbarians north of the Alps. From 169 onwards he had to struggle hard against the German Quadi, Marcomani, Vandals, and others until success came in 174. In 175 he pacified affairs in Asia after a revolt by Avidius. War with Germans was renewed during which he caught some disease and died by the Danube in March 180. The famous Meditations of Marcus Aurelius represents reflections written in periods of solitude during the emperor's military campaigns. Originally intended for his private guidance and self-admonition, the Meditations has endured as a potent expression of Stoic belief. It is a central text for students of Stoicism as well as a unique personal guide to the moral life. (shrink)

This book provides a new interpretation of Hegel's philosophy, arguing that his theory of reason and thinking revolve around the concept of organic life. Through a detailed analysis of Hegel's philosophy and Kant's influence, Karen Ng shows that Hegel's unique contribution is that cognitive capacities are indexed to species capacities, where embodiment and the relation to the environment are central in processes of mind.

All the notes to the Farquharson translation, amplifying the twelve books of the "Meditations," are included in this volume.

Published in 1891, Edmund Husserl’s first book, Philosophie der Arithmetik, aimed to “prepare the scientific foundations for a future construction of that discipline.” His goals should seem reasonable to contemporary philosophers of mathematics: . . . through patient investigation of details, to seek foundations, and to test noteworthy theories through painstaking criticism, separating the correct from the erroneous, in order, thus informed, to set in their place new ones which are, if possible, more adequately secured. [7, p. 5]2 But the (...) ensuing strategy for grounding mathematical knowledge sounds strange to the modern ear. For Husserl cast his work as a sequence of “psychological and logical investigations,” providing a psychological analysis.. (shrink)

Ng and singer derive the principle of utility from the fact of finite sensibility and another principle, weak majority preference: "for a community of n individuals choosing between two possibilities, x and y, if no individual prefers y to x, and at least n/2 individuals prefer x to y, then x increases social welfare and is preferable." this derivation is regarded as incorrect in a comment. this reply explains why the derivation is valid and shows that the comment is based (...) on confusing a general social ordering with a utilitarian one.

Marcus Aurelius was Emperor of Rome from 121 to 180. Thoughts of Marcus Aurelius was written for school age children. The author believed that children should be given the wisdom of great leaders from all eras. Marcus Aurelius believed that human happiness arises in part from man's acceptance of his duties and responsibilities. He believed that one should accept calmly what cannot be avoided and perform one's duties as well as possible. "It was the doctrine of (...) class='Hi'>Marcus Aurelius that most of the ills of life come to us from our own imagination, that it was not in the power of others seriously to interfere with the calm, temperate life of an individual, and that when a fellow being did anything to us that seemed unjust he was acting in ignorance, and that instead of stirring up anger within us it should stir our pity for him. Oftentimes by careful self-examination we should find that the fault was more our own than that of our fellow, and our sufferings were rather from our own opinions than from anything real.".

This new edition brings Farquharson's authoritative 1944 translation up to date and includes a helpful introduction and notes for the student and general reader. Rutherford includes a selection of letters from Marcus to his tutor Fronto--most of which date from his earlier years--that offer personal detail and help to fill out the somber portrait of the emperor that is found in the Meditations.

The Meditations are a set of personal reflections by Marcus Aurelius. He writes about the vicissitudes of his own life and explores how to live wisely and virtuously in an unpredictable world. Part of the Macmillan Collector’s Library; a series of stunning, clothbound, pocket sized classics with gold foiled edges and ribbon markers. These beautiful books make perfect gifts or a treat for any book lover. This edition is translated by A. S. L. Farquharson and features an introduction by (...) John Sellars. Marcus Aurelius was Roman emperor at the height of Rome’s power and prosperity. Under his rule the Mediterranean world was better governed than at any time since. He was also a follower of the Stoic tradition of philosophy, and one of its finest advocates, both in the clarity and simplicity of his writing, and in the uprightness of his life. Meditations was written during the decade or more Aurelius spent campaigning in the remote Danube region towards the end of his life. The aphorisms show how for him, as perhaps for us all, the answer to life lies in keeping a calm and rational mind and in refusing to be cast down or alarmed by things over which we have no control.

Welfare biology is the study of living things and their environment with respect to their welfare. Despite difficulties of ascertaining and measuring welfare and relevancy to normative issues, welfare biology is a positive science. Evolutionary economics and population dynamics are used to help answer basic questions in welfare biology : Which species are affective sentients capable of welfare? Do they enjoy positive or negative welfare? Can their welfare be dramatically increased? Under plausible axioms, all conscious species are plastic and all (...) plastic species are conscious. More complex niches favour the evolution of more rational species. Evolutionary economics also supports the common-sense view that individual sentients failing to survive to mate suffer negative welfare. A kind of God-made fairness between species is also unexpectedly found. The contrast between growth maximization, average welfare, and total welfare maximization is discussed. It is shown that welfare could be increased without even sacrificing numbers. Since the long-term reduction in animal suffering depends on scientific advances, strict restrictions on animal experimentation may be counter-productive to animal welfare. (shrink)

In the Critique of Pure Reason, Kant famously criticizes traditional metaphysics and its proofs of immortality, free will and God's existence. What is often overlooked is that Kant also explains why rational beings must ask metaphysical questions about 'unconditioned' objects such as souls, uncaused causes or God, and why answers to these questions will appear rationally compelling to them. In this book, Marcus Willaschek reconstructs and defends Kant's account of the rational sources of metaphysics. After carefully explaining Kant's conceptions (...) of reason and metaphysics, he offers detailed interpretations of the relevant passages from the Critique of Pure Reason in which Kant explains why reason seeks 'the unconditioned'. Willaschek offers a novel interpretation of the Transcendental Dialectic, pointing up its 'positive' side, while at the same time it uncovers a highly original account of metaphysical thinking that will be relevant to contemporary philosophical debates.

Utilitarianism seems to be going out of fashion, amidst increasing concerns for issues of freedom, equality, and justice. At least, anti-utilitarian and non-utilitarian moral philosophers have been very active. This paper is a very modest attempt to defend utilitarianism in particular and welfarism in general. Section I provides an axiomatic defence of welfarism and utilitarianism. Section II discusses the divergences between individual preferences and individual welfares and argues in favour of welfare utilitarianism. Section III criticizes some non-utilitarian principles, including knowledge (...) as intrinsically good, rights-based ethics, and Rawls's second principle. Section IV argues that most objections to welfarism are probably based on the confusion of non-ultimate considerations with basic values. This is discussed with reference to some recent philosophical writings which abound with such confusion. Section V argues that the acceptance of utilitarianism may be facilitated by the distinction between ideal morality and self-interest which also resolves the dilemma of average versus total utility maximization in optimal population theory.

One of the most important texts of modern times, Herbert Marcuse's analysis and image of a one-dimensional man in a one-dimensional society has shaped many young radicals' way of seeing and experiencing life. Published in 1964, it fast became an ideological bible for the emergent New Left. As Douglas Kellner notes in his introduction, Marcuse's greatest work was a 'damning indictment of contemporary Western societies, capitalist and communist.' Yet it also expressed the hopes of a radical philosopher that human freedom (...) and happiness could be greatly expanded beyond the regimented thought and behaviour prevalent in established society. For those who held the reigns of power Marcuse's call to arms threatened civilization to its very core. For many others however, it represented a freedom hitherto unimaginable. (shrink)

Dewey’s book is the first systematic attempt at a pragmatistic logic (since the work of Peirce). Because of the ambiguity of the concept of pragmatism, the author rejects the concept in general. But, if one interprets pragmatism correctly, then this book is ‘through and through Pragmatistic’. What he understands as ‘correct’ will become clear in the following account. The book takes its subject matter far beyond the traditional works on logic. It is a material logic first in the sense that (...) the matter of logic (the ‘objects’, that with which logical thought has to do) is thoroughly included in the cycle of investigation, and logical ‘forms’ are discussed only in their constitutional connection with this ..

This book outlines a unified theory of prudence and morality that merges a wide variety of findings in behavioral neuroscience with philosophically sophisticated normative theorizing. Chapter 1 lays out the emerging behavioral neuroscience of prudence and morality. Chapter 2 then outlines a new theory of prudence as fairness to oneself across time. Chapter 3 then derives a revised version of my 2016 moral theory--Rightness as Fairness--from this theory of prudence, showing how the theory of prudence defends Rightness as Fairness against (...) various critiques and unifies prudence, morality, and justice. Chapter 4 then argues that this theory explains a variety of normative philosophical and empirical neuroscientific phenomena better than alternatives. Finally, Chapter 5 responds to potential objections and explores future research avenues. (shrink)

My title may generate some perplexity. It is certainly not a familiar one. So I should make it plain at the outset that I shall not be talking about the ethics of organizations or associations or groups. I want to direct attention to the ethical and valuational questionsassociated with social institutions, and I distinguish institutions from associations and organizations. One question I am aiming at is whether the principles and standards applicable to moral judgments of actions and of persons—call them (...) individual principles—are also applicable, or applicable with only minor changes, to the judgment and critique and evaluation of institutions and practices. This is not the sole question of institutional ethics, but it is a main one. (shrink)

A person's values are what that person regards as or thinks important; a society's values are what that society regards as important. A society's values are expressed in laws and legislatively enacted policies, in its mores, social habits, and positive morality. Any body's values—an individual person's or a society's—are subject to change, and in our time especially. An individual manifests his or her values in expressions of approval or disapproval, of admiration or disdain, by seeking or avoidance behaviour, and by (...) his or her characteristic activities. What one values one seeks for or tries to maintain. Sometimes attaining it leads to unexpected enlightenment—that isn't what one wanted after all. But a person's values are discovered most significantly in a reflective way by becoming aware of what one is willing to give up to attain or maintain one's values. This is the price one is willing to pay for it, and values are occasionally, and in the money and stock markets always, expressed in terms of price. This can be significant or it can be misleading; it depends on how it is interpreted. Not everything has a monetary equivalent, despite the attempts of the law to provide recovery for damages in monetary terms, and despite the cynical maxim, ‘Everyone has his price’. (shrink)

It is impossible to hold patently contradictory beliefs in mind together at once. Why? Because we know that it is impossible for both to be true. This impossibility is a species of rational necessity, a phenomenon that uniquely characterizes the relation between one person's beliefs. Here, Eric Marcus argues that the unity of the rational mind--what makes it one mind--is what explains why, given what we already believe, we can't believe certain things and must believe certain others in this (...) special sense. What explains this is that beliefs, and the inferences by which we acquire them, are constituted by a particular kind of endorsement of those very states and acts. This, in turn, entails that belief and inference are essentially self-conscious: to hold a belief or to make an inference is at the same time to know that one does. An examination of the nature of belief and inference, in light of the phenomenon of rational necessity, reveals how the unity of the rational mind is a function of our knowledge of ourselves as bound to believe the true. Rational self-consciousness is the form of mental togetherness. (shrink)

Two leaders in the field offer a compelling analysis of the current state of the art and reveal the steps we must take to achieve a truly robust artificial intelligence. Despite the hype surrounding AI, creating an intelligence that rivals or exceeds human levels is far more complicated than we have been led to believe. Professors Gary Marcus and Ernest Davis have spent their careers at the forefront of AI research and have witnessed some of the greatest milestones in (...) the field, but they argue that a computer beating a human in Jeopardy! does not signal that we are on the doorstep of fully autonomous cars or superintelligent machines. The achievements in the field thus far have occurred in closed systems with fixed sets of rules, and these approaches are too narrow to achieve genuine intelligence. The real world, in contrast, is wildly complex and open-ended. How can we bridge this gap? What will the consequences be when we do? Taking inspiration from the human mind, Marcus and Davis explain what we need to advance AI to the next level, and suggest that if we are wise along the way, we won't need to worry about a future of machine overlords. If we focus on endowing machines with common sense and deep understanding, rather than simply focusing on statistical analysis and gatherine ever larger collections of data, we will be able to create an AI we can trust--in our homes, our cars, and our doctors' offices. Rebooting AI provides a lucid, clear-eyed assessment of the current science and offers an inspiring vision of how a new generation of AI can make our lives better. (shrink)

It is of the very definition of any "classic" work that it will not only introduce a new depth and direction of thought, but that its original insights endure. When it first appeared in 1940, Reason and Revolution by Herbert Marcuse was acclaimed for its profound and undistorted reading of Hegel's social and political theory. Today, the appreciation of Marcuse's work has remained high, more relevant now than ever before. In the rapidly changing context of post-Cold War political realities, there (...) is no better guide than Marcuse to where we have been and to what we might expect. As he well understood, turbulent and spectacular political events always ran within channels earlier set by political theory; and he equally understood that it was Hegel's often unappreciated and misunderstood theory which actually set a fundamental path of modern political life. It is a fortunate combination to have a scholar of Marcuse's brilliance and lucid honesty addressing the sources and consequences of Hegel's social theory. (shrink)

This collection assembles some of Herbert Marcuse’s most important work and presents for the first time his responses to and development of classic Marxist approaches to revolution and utopia, as well as his own theoretical and political perspectives. This sixth and final volume of Marcuse's collected papers shows Marcuse’s rejection of the prevailing twentieth-century Marxist theory and socialist practice - which he saw as inadequate for a thorough critique of Western and Soviet bureaucracy - and the development of his revolutionary (...) thought towards a critique of the consumer society. Marcuse's later philosophical perspectives on technology, ecology, and human emancipation sat at odds with many of the classic tenets of Marx’s materialist dialectic which placed the working class as the central agent of change in capitalist societies. As the material from this volume shows, Marcuse was not only a theorist of Marxist thought and practice in the twentieth century, but also proves to be an essential thinker for understanding the neoliberal phase of capitalism and resistance in the twenty-first century. A comprehensive introduction by Douglas Kellner and Clayton Pierce places Marcuse’s philosophy in the context of his engagement with the main currents of twentieth century philosophy while also providing important analyses of his anticipatory theorization of capitalist development through a neoliberal restructuring of society. The volume concludes with an afterword by Peter Marcuse. (shrink)

At the beginning of one of his inimitable discourses William James once said, ‘I am only a philosopher, and there is only one thing that a philosopher can be relied on to do, and that is, to contradict other philosophers’. 1 In his succeeding discourse James himself departed from this theme. And so shall I. I shall not be contradicting other philosophers—at least not very often. What I aim to do is to take a fresh look at one of the (...) main traditions in American philosophy for insight and illumination on a way of dealing with some of the most serious issues of our time. But before I turn to that, my main theme, I want to pursue for a bit some variations on another, the cultural relevance of philosophy, for, as I view the matter, they are related. (shrink)

Chapter 1 of this book argued that moral philosophy should be based on seven principles of theory selection adapted from the sciences. Chapter 2 argued that these principles support basing normative moral philosophy on a particular problem of diachronic instrumental rationality: the ‘problem of possible future selves.’ Chapter 3 argued that a new moral principle, the Categorical-Instrumental Imperative, is the rational solution to this problem. Chapter 4 argued that the Categorical-Instrumental Imperative has three equivalent formulations akin to but superior to (...) Kant’s formulations of the Categorical Imperative. Chapter 5 argued that my principle’s three formulations make it rational to adopt a Moral Original Position to derive moral principles. The present chapter derives Four Principles of Fairness from the Moral Original Position--principles of coercion minimization, mutual assistance, fair negotiation, and virtue—and unifies them into a single principle of rightness: Rightness as Fairness. Finally, this chapter argues that Rightness as Fairness entails a novel approach to applied ethics called ‘principled fair negotiation’, illustrating how the theory provides a plausible new framework for addressing applied cases including lying, suicide, trolleys, torture, distribution of scarce resources, poverty, and the ethical treatment of animals.

This classic book is Marcuse's masterful interpretation of Hegel's philosophy and the influence it has had on European political thought from the French Revolution to the present day. Marcuse brilliantly illuminates the implications of Hegel's ideas with later developments in European thought, particularily with Marxist theory.

Eli Hirsch recently suggested the metaontological doctrine of so-called "quantifier variance", according to which ontological disputes—e.g. concerning the question whether arbitrary, possibly scattered, mereological fusions exist, in the sense that these are recognised as objects proper in our ontology—can be defused as insubstantial. His proposal is that the meaning of the quanti er `there exists' varies in such debates: according to one opponent in this dispute, some existential statement claiming the existence of, e.g., a scattered object is true, according to (...) the other it is not. This paper argues that Hirsch's proposal leads into inconsistency. (shrink)
