In this paper we take a fresh look at the information retrieval problem of balancing recall with precision in electronic document extraction. We examine the IR constructs of uncertainty, context and relevance, proposing a new process model for context learning, and introducing a new IT artifact designed to support user driven learning by leveraging explicit knowledge to discover implicit knowledge within a corpus of documents. The IT artifact is a prototype designed to present a small set of extracted documents from (...) a targeted corpus based upon user inputted criteria. The prototype provides the user with the opportunity to balance exploration and exploitation, via iterative relevance feedback to address the problem of imprecision resulting from uncertainty. We model the problem as an exploration–exploitation dilemma and apply it to a specific case of IR called eDiscovery. We conduct a series of behavioral experiments to evaluate the model and the artifact. Our initial findings indicate that the proposed model and the artifact improve performance in the IR result.

This book examines central themes in the thought of Rabbi Hasdai Crescas (c. 1340-1410/11), the great Catalan Jewish philosopher who contributed to the revolution of modern science and profoundly influenced Spinoza. Part I treats of Crescas' radical critique of the Aristotelian concepts of space, time, and the vacuum, and analyzes his vision of an infinite universe; it discusses his criticisms of Maimonides' proofs of God, and expounds his own proof; and it concludes with a discussion of his concept of God (...) as infinite Love. Part II contains three essays on Crescas' strictly deterministic theory of human choice. (shrink)

Maimonides requires the multitude to observe many ceremonial commandments, while Spinoza makes no such demand. This chapter focuses on some of the main points of agreement between Maimonides and Spinoza on true religion, the religion of reason, or philosophic religion. True religion includes also piety, that is, moral conduct, which follows from the rational life. The piety of the philosopher and the non‐philosopher both consist in doing good to others. Maimonides’ approach to true religion adumbrates Spinoza's. Spinoza's concept of amor (...) Dei intellectualis echoes Maimonides’ concept of the passionate intellectual love of God. Spinoza's concept of piety is adumbrated in Maimonides. The Maimonidean thrust of Spinoza's concept of true religion is evident in his discussion of “the divine Law” or, more precisely, “the natural divine Law” and the summum bonum in TTP4. In Maimonides’ language, true religion is based on the intelligibilia and popular religion on generally accepted opinions. (shrink)

Martin Buber’s essay “False Prophets” was written in Hebrew in Jerusalem two years after he fled Nazi Germany and assumed a professorship at the Hebrew University of Jerusalem. The essay offers a political analysis of the dramatic confrontation between the prophets Jeremiah and Hananiah. It speaks about the dangers of nationalism in Jeremiah’s biblical Jerusalem and in Buber’s own modern Jerusalem, eight years before the proclamation of the State of Israel. Who is the real lover of the homeland, Buber asks, (...) the patriot who cares not about human beings, or the concerned individual who is willing to compromise in order to avoid destruction and save lives? When does nationalism become malignant? What is the difference between a true prophet and a false one? (shrink)

In the course of his studies on Kabbalah, Moshe Idel has written on the influence of Kabbalists on philosophy. He suggests that Spinoza was influenced by the Kabbalah regarding his expressions “Deus sive Natura“ and “amor Dei intellectualis.” The 13th-century ecstatic Kabbalist Rabbi Abraham Abulafia and many authors after him cited the numerical equivalence of the Hebrew words for God and Nature: elohim = ha-teba` = 86. This striking numerical equivalence may be one of the sources of Spinoza’s expression “Deus (...) sive Natura.” The same Kabbalist used the Hebrew expression “ahabah elohit sikhlit“ (“divine intellectual love”), which may underlie Spinoza’s expression “amor Dei intellectualis.” Abulafia’s expression “ahabah elohit sikhlit“ is repeated by the popular 15th-century Maimonidean philosopher, Rabbi Abraham Shalom.

In his “Spinoza’s TTP , Maimonides, and Kant” (1968), Pines compared Spinoza’s dogmas of universal faith ( TTP , 14) with Kant’s postulates of practical reason ( Critique of Practical Reason , part 1). According to him, Spinoza’s dogmas, like Maimonides’ “necessary beliefs” ( Guide 3:28), are postulates necessary for political welfare, and do not fall under the jurisdiction of theoretical reason. They define the faith of the common person, not that of the philosopher. Kant, in his remarks about Spinoza (...) as an “upright skeptic,” mistakenly thought his dogmas were true beliefs, not necessary ones; and his notion of postulates of practical reason seems to have been in part influenced by his mistaken view of Spinoza’s dogmas. The transformation of Maimonides’ “necessary beliefs” into Kant’s “postulates of practical reason,” as narrated by Pines, recalls the similar transformation of “Averroism” into “Christian Averroism” in the thirteenth century. In essays written from the late 1970s until his death in 1990, Pines returned to the theme of Maimonides and Kant, and argued convincingly that Maimonides’ epistemology was “critical” in the Kantian sense. However, his related argument that Maimonides’ religious sensibility was similar to Kant’s is less convincing. Unlike Kant, Maimonides did not think that critical epistemology made room for faith, but held that it caused one to tremble in awe. Like Spinoza, he identified true faith with intellectual knowledge, not something beyond it. His distinctiveness as a philosopher is that he was a God-intoxicated Knower like Spinoza, but a critical epistemologist like Kant. (shrink)

How have human cultures engaged with and thought about animals, plants, rocks, clouds, and other elements in their natural surroundings? Do animals and other natural objects have a spirit or soul? What is their relationship to humans? In this new study, Graham Harvey explores current and past animistic beliefs and practices of Native Americans, Maori, Aboriginal Australians, and eco-pagans. He considers the varieties of animism found in these cultures as well as their shared desire to live respectfully within larger (...) natural communities. Drawing on his extensive casework, Harvey also considers the linguistic, performative, ecological, and activist implications of these different animisms. (shrink)

Liberty and freedom are frequently invoked to justify political action. Presidents as diverse as Woodrow Wilson, Franklin Delano Roosevelt, John F. Kennedy, Ronald Reagan, and George W. Bush have built their policies on some version of these noble values. Yet in practice, idealist agendas often turn sour as they confront specific circumstances on the ground. Demonstrated by incidents at Abu Ghraib and Guantánamo Bay, the pursuit of liberty and freedom can lead to violence and repression, undermining our trust in universal (...) theories of liberalism, neoliberalism, and cosmopolitanism. Combining his passions for politics and geography, David Harvey charts a cosmopolitan order more appropriate to an emancipatory form of global governance. Political agendas tend to fail, he argues, because they ignore the complexities of geography. Incorporating geographical knowledge into the formation of social and political policy is therefore a necessary condition for genuine democracy. Harvey begins with an insightful critique of the political uses of freedom and liberty, especially during the George W. Bush administration. Then, through an ontological investigation into geography's foundational concepts—space, place, and environment—he radically reframes geographical knowledge as a basis for social theory and political action. As Harvey makes clear, the cosmopolitanism that emerges is rooted in human experience rather than illusory ideals and brings us closer to achieving the liberation we seek. (shrink)

The Epicurean philosophical system has enjoyed much recent scrutiny, but the question of its philosophical ancestry remains largely neglected. It has often been thought that Epicurus owed only his physical theory of atomism to the fifth-century BC philosopher Democritus, but this study finds that there is much in his ethical thought which can be traced to Democritus. It also finds important influences on Epicurus in Democritus' fourth-century followers such as Anaxarchus and Pyrrho, and in Epicurus' disagreements with his own Democritean (...) teacher Nausiphanes. The result is not only a fascinating reconstruction of a lost tradition, but also an important contribution to the philosophical interpretation of Epicureanism, bearing especially on its ideal of tranquillity and on the relation of ethics to physics.

Cosmopsychism, the idea that the universe is conscious, is experiencing something of a revival as an explanation of consciousness in philosophy of mind and is also making inroads into philosophy of religion. In the latter field, it has been used to formulate models of certain forms of theism, such as pantheism and panentheism, and has also been proposed as a rival to the classical theism of the Abrahamic faiths. It has been claimed by Philip Goff that a certain form of (...) cosmopsychism, namely agentive cosmopsychism, poses a threat to classical theism because it can explain features of the universe like fine-tuning without having to deal with the problem of evil. This is because, unlike the classical theist, the cosmopsychist can deny at least one of the divine attributes motivating the problem of evil, namely omniscience, omnipotence, and omnibenevolence. In this paper, I shall consider which of the divine attributes the cosmopsychist should focus on when responding to the problem of evil and shall conclude that the rejection of omnibenevolence is the most satisfactory option.

Once upon a time, logical conventionalism was the most popular philosophical theory of logic. It was heavily favored by empiricists, logical positivists, and naturalists. According to logical conventionalism, linguistic conventions explain logical truth, validity, and modality. And conventions themselves are merely syntactic rules of language use, including inference rules. Logical conventionalism promised to eliminate mystery from the philosophy of logic by showing that both the metaphysics and epistemology of logic fit into a scientific picture of reality. For naturalists of all (...) stripes, this was paradise. Alas, paradise was lost. By the end of the twentieth century, logical conventionalism had been almost universally abandoned. But more recently, it has been revitalized. This chapter provides an overview of logical conventionalism and its history, clears away misunderstandings, and briefly responds to both the canonical objections to conventionalism (from Quine, Dummett, Boghossian, and many others) as well as new objections (from Field and Golan). From paradise lost, to paradise regained: logical conventionalism is back. (shrink)

In this article, I show how Bruschi’s Le matérialisme politique de Louis Althusser offers, against all attempts conjure up a self-generating general theory of history, a reconstruction of Althusser’s work that shows how its systematicity relies upon the unfinished, incomplete and provisional character of scientific research, always subject to constant rectification. I then claim that, from the conceptualisa-tion of the reproduction of the mode of production as dependent upon the singularity of the con-juncture, to the theorisation of the encounter as (...) the source of historical necessity, this constant re-working is crucial to Althusser’s ability to grasp the reality of class struggle.

This book is the first extensive treatment of Husserl's phenomenology of time-consciousness. Nicolas de Warren uses detailed analysis of texts by Husserl, some only recently published in German, to examine Husserl's treatment of time-consciousness and its significance for his conception of subjectivity. He traces the development of Husserl's thinking on the problem of time from Franz Brentano's descriptive psychology, and situates it in the framework of his transcendental project as a whole. Particular discussions include the significance of time-consciousness for (...) other phenomenological themes: perceptual experience, the imagination, remembrance, self-consciousness, embodiment, and the consciousness of others. The result is an illuminating exploration of how and why Husserl considered the question of time-consciousness to be the most difficult, yet also the most central, of all the challenges facing his unique philosophical enterprise"--Provided by publisher.

The ancient philosophical school of Epicureanism tried to argue that death is "nothing to us." Were they right? James Warren provides a comprehensive study and articulation of the interlocking arguments against the fear of death found not only in the writings of Epicurus himself, but also in Lucretius' poem De rerum natura and in Philodemus' work De morte. These arguments are central to the Epicurean project of providing ataraxia (freedom from anxiety) and therefore central to an understanding of Epicureanism (...) as a whole. They also offer significant resources for modern discussions of the value of death--one which stands at the intersection of metaphysics and ethics. If death is the end of the subject, and the subject can not be benefited nor harmed after death, is it reasonable nevertheless to fear the ceasing-to-be? If the Epicureans are not right to claim that the dead can neither be benefited nor harmed, what alternative models might be offered for understanding the harm done by death and do these alternatives suffer from any further difficulties? The discussion involves consideration of both ethical and metaphysical topics since it requires analysis not only of the nature of a good life but also the nature of personal identity and time. A number of modern philosophers have offered criticisms or defences of the Epicureans' views. Warren explores and evaluates these in the light of a systematic and detailed study of the precise form and intention of the Epicureans' original arguments. Warren argues that the Epicureans also were interested in showing that mortality is not to be regretted and that premature death is not to be feared. Their arguments for these conclusions are to be found in their positive conception of the nature of a good and complete life, which divorce the completeness of a life as far as possible from considerations of its duration. Later chapters investigate the nature of a life lived without the fear of death and pose serious problems for the Epicureans being able to allow any concern for the post mortem future and being able to offer a positive reason for prolonging a life which is already complete in their terms.

Because of the “all-or-none” character of nervous activity, neural events and the relations among them can be treated by means of propositional logic. It is found that the behavior of every net can be described in these terms, with the addition of more complicated logical means for nets containing circles; and that for any logical expression satisfying certain conditions, one can find a net behaving in the fashion it describes. It is shown that many particular choices among possible neurophysiological assumptions (...) are equivalent, in the sense that for every net behaving under one assumption, there exists another net which behaves under the other and gives the same results, although perhaps not in the same time. Various applications of the calculus are discussed. (shrink)

Marxism's collapse in the twentieth century profoundly altered the style and substance of Western European radical thought. To build a more robust form of democratic theory and action, prominent theorists moved to reject revolution, abandon class for more fragmented models of social action, and elevate the political over the social. Acknowledging the constructedness of society and politics, they chose the "symbolic" as a concept powerful enough to reinvent leftist thought outside a Marxist framework. Following Maurice Merleau-Ponty's Adventures of the Dialectic, (...) which reassessed philosophical Marxism at mid century, Warren Breckman critically revisits these thrilling experiments in the aftermath of Marxism. The post-Marxist idea of the symbolic is dynamic and complex, uncannily echoing the early German Romantics, who first advanced a modern conception of symbolism and the symbolic. Hegel and Marx denounced the Romantics for their otherworldly and nebulous posture, yet post-Marxist thinkers appreciated the rich potential of the ambiguities and paradoxes the Romantics first recognized. Mapping different ideas of the symbolic among contemporary thinkers, Breckman traces a fascinating reflection of Romantic themes and resonances, and he explores in depth the effort to reconcile a radical and democratic political agenda with a politics that does not privilege materialist understandings of the social. Engaging with the work of Claude Lévi-Strauss, Cornelius Castoriadis, Claude Lefort, Marcel Gauchet, Ernesto Laclau, Chantal Mouffe, and Slavoj Žižek, Breckman uniquely situates these important theorists within two hundred years of European thought and extends their profound relevance to today's political activism.

We face reality presented with the data of conscious experience and nothing else. The project of early modern philosophy was to build a complete theory of the world from this starting point, with no cheating. Crucial to this starting point is the data of conscious sensory experience – sense data. Attempts to avoid this project often argue that the very idea of sense data is confused. But the sense-data way of talking, the sense-data language, can be freed from every blemish (...) using ideas from contemporary metaontology. We can adopt a sense-data framework that vindicates the traditional claims of sense-data theories and leads to plausible theories of perception and color. We can, we should, and in a sense, we must. Yet when we do, we face the traditional problem of external world skepticism, head-on. The real challenge of skepticism is forced upon us; it cannot honestly be avoided using externalist tricks, burden of proof shifting, or other razzle dazzle. But the challenge can be met: we are rational to posit the external world as the best explanation of the many synchronic and diachronic patterns over our sense-data. This paper argues for all of these points and ends with a plea for analytic empiricism – a traditional sense-data version of empiricism that uses all of the tools of analytic philosophy while avoiding the more questionable doctrines of the Vienna Circle (phenomenalism, verificationism). Analytic empiricism is our last best hope for completing the great philosophical project of early modern philosophy. (shrink)

In his arguments that science itself can answer moral questions, Sam Harris often appeals to our intuitions about the badness of suffering. If we share these intuitions, Harris argues, we’ve taken a significant step in conceding to a basically utilitarian worldview. In this chapter, I critically assess Harris’ arguments and find them deeply wanting.

Writings by a thinker—a psychiatrist, a philosopher, a cybernetician, and a poet—whose ideas about mind and brain were far ahead of his time. Warren S. McCulloch was an original thinker, in many respects far ahead of his time. McCulloch, who was a psychiatrist, a philosopher, a teacher, a mathematician, and a poet, termed his work “experimental epistemology.” He said, “There is one answer, only one, toward which I've groped for thirty years: to find out how brains work.” Embodiments of (...) Mind, first published more than fifty years ago, teems with intriguing concepts about the mind/brain that are highly relevant to recent developments in neuroscience and neural networks. It includes two classic papers coauthored with Walter Pitts, one of which applies Boolean algebra to neurons considered as gates, and the other of which shows the kind of nervous circuitry that could be used in perceiving universals. These first models are part of the basis of artificial intelligence. Chapters range from “What Is a Number, that a Man May Know It, and a Man, that He May Know a Number,” and “Why the Mind Is in the Head,” to “What the Frog's Eye Tells the Frog's Brain” (with Jerome Lettvin, Humberto Maturana, and Walter Pitts), “Machines that Think and Want,” and “A Logical Calculus of the Ideas Immanent in Nervous Activity” (with Walter Pitts). Embodiments of Mind concludes with a selection of McCulloch's poems and sonnets. This reissued edition offers a new foreword and a biographical essay by McCulloch's one-time research assistant, the neuroscientist and computer scientist Michael Arbib. (shrink)

Warren Quinn was widely regarded as a moral philosopher of remarkable talent. This collection of his most important contributions to moral philosophy and the philosophy of action has been edited for publication by Philippa Foot. Quinn laid out the foundations for an anti-utilitarian moral philosophy that was critical of much contemporary work in ethics, such as the anti-realism of Gilbert Harman and the neo-subjectivism of Bernard Williams. Quinn's own distinctive moral theory is developed in the discussion of substantial, practical (...) moral issues. For example, there are important pieces here on the permissibility of abortion, the justification of punishing criminals when no particular good seems likely to result, and on the distinction between killing and allowing to die, a distinction crucial to the subject of euthanasia and other topics in medical ethics. The volume would be ideally suited to upper-level undergraduate courses and graduate seminars on the foundations of ethics. (shrink)

The recent philosophy of Quantum Bayesianism, or QBism, represents an attempt to solve the traditional puzzles in the foundations of quantum theory by denying the objective reality of the quantum state. Einstein had hoped to remove the spectre of nonlocality in the theory by also assigning an epistemic status to the quantum state, but his version of this doctrine was recently proved to be inconsistent with the predictions of quantum mechanics. In this essay, I present plausibility arguments, old and new, (...) for the reality of the quantum state, and expose what I think are weaknesses in QBism as a philosophy of science. (shrink)
